Indoor Air Quality

Posted on October 28, 2019October 28, 2019 by Helen

Indoor Air Quality

Poor air quality can cause negative effects towards your health such as allergies, respiratory illnesses, and skin problems. Considering that we spend more than 90% of our time indoors, it’s important that indoor air is clean and pollutant-free to protect our health and wellbeing.

Indoor air quality statistics

According to the EPA, indoor air pollution is among the top 5 environmental risks to public health. In fact, indoor air quality can be up to 5 times worse than outdoor air quality!

Effects of indoor air pollutants towards your health may range from symptoms such as eye and throat irritation, to respiratory diseases that may arise from long term exposure to indoor pollution.

What is in indoor air

Indoor air could harbour a range of pollutants unseen to the naked eye. Airborne particles such as diesel exhaust, carbon, dust, smoke, fibres, and pollen easily enter the home through opened doors and windows.

Cooking odours, pet odours, chemicals, sink or drain smells contribute to an unhealthy variety of unpleasant and toxic household odours and gases.

Around the home, furniture, office equipment, cleaning supplies, paint, glue and varnishes are just some of the unhealthy Volatile Organic Compounds (VOCs) that are harmful to our long term health.

Not to mention, there could be a range of microorganisms such as bacteria, mould, and viruses, floating around our home!

Sources of indoor air pollutants

You may think your home air quality is perfectly fine, but these pollutants are well hidden from the naked eye. Some don’t emit a distinct smell or show obvious physical signs, so you barely notice them around your home.

However, the sources of these indoor air pollutants are everywhere in our home. Pollutants such as mould and mildew could be lingering in our bathroom and laundry room. We could also be exposed to Volatile Organic Compounds (VOCs) from paint, varnishes, upholstery, furnishing and carpets.

That’s why having an air purifier is so important at home. Air purifiers help to clean the air of unwanted pollutants. They are especially useful for those suffering from asthma or allergies.

Air purifier benefits

Air purifiers are appliances that filter out pollutants such as dust, pollen, viruses, bacteria, and odours from indoor air. With the help of air purifiers, we can improve indoor air quality and protect the health of ourselves and our families.Cleaner air provides long term benefits by reducing respiratory diseases and airborne infections caused by indoor air pollutants. Moreover, air purifiers also help to improve air circulation and eliminate mould spore buildup.Indoor air pollutants are harmful to long term health, so consider investing in an air purifier to improve indoor air quality at home.

2019 indoor air pollution status

Posted on October 22, 2019October 22, 2019 by Helen

2019 indoor air pollution status

The degree of indoor air pollution decreases as the number of renovations is completed! The office is the hardest hit by air pollution, with a failure rate of up to 90%. In the measurement of scenes such as homes, offices, schools, government and financial institutions, the proportion of office air quality is the highest, reaching 90%. The pass rate of the family is 35%; the pass rate of the government and financial institutions is 20%; the pass rate of the school is 23%.

The higher the temperature, the more harmful gases are released.

The indoor air quality is related to the ambient temperature. It can be seen from the qualification rate and the ambient temperature that the pass rate has a negative correlation with the temperature increase.

Choose environmentally friendly decorative materials

The selection of materials that meet national standards and low pollution is fundamental to reducing the amount of pollutants in indoor air. Use paints, glues and coatings produced by regular manufacturers; use non-polluting or less polluting water-based materials.

Choose a reasonable decoration design and construction process

Selecting a reasonable decoration design can maximize the use of space and indoor ventilation; choosing a reasonable construction process can also effectively prevent indoor pollution sources.

Effective ventilation is a more effective technical measure to control indoor pollution

It is a key measure to reduce pollution by using indoor air purifiers and new fans that have effective effects, increasing the frequency of indoor ventilation, always maintaining good ventilation conditions, and opening windows when outdoor air is good.

At present, indoor environmental pollution is also becoming more and more serious. About 300 kinds of pollutants can be detected indoors, and about 60% of human diseases are related to air pollution.

The pollution caused by indoor air mainly comes from the following five aspects

Posted on October 21, 2019October 21, 2019 by Helen

The pollution caused by indoor air mainly comes from the following five aspects

First, the human body breathing, smoke;

Second, decoration materials, daily necessities;

Third, microorganisms, viruses, bacteria;

Fourth, kitchen fumes;

Fifth, air conditioning syndrome.

These pollutants enter the human body with breathing and accumulate for a long time, which seriously endangers people’s health.

Human breathing, smoke

The research results show that the human body will produce about 500 kinds of chemical substances in the metabolism process, and 149 kinds of pollutants discharged through the respiratory tract, the pathogens emitted by the human body and a variety of odors, among which a variety of toxic components are mixed, and must not be ignored. There are as many as 171 kinds of body waste discharged by the human body through the sweat glands of the skin, such as urea and ammonia. In addition, the cells of the human skin are about 90% of the air dust. If the concentration is too high, it will form indoor biological pollution, affect human health, and even induce a variety of diseases.

Smoking is one of the main sources of indoor air pollution. The composition of the smoke is complex, with solid and gas phases. Approved by the International Cancer Institute expert group and through animal carcinogenic experiments, there are more than 40 ‘carcinogens’ in tobacco smoke. Smoking can significantly increase the incidence of cardiovascular disease and is the ‘number one killer’ of human health.

Decoration materials, daily necessities

Interior decoration using a variety of paints, paints, wall coverings, adhesives, artificial boards, marble floors and newly purchased furniture, etc., will emit phenol, formaldehyde, asbestos dust, radioactive materials, etc., which can cause headaches, insomnia, dermatitis and Allergies and other reactions reduce the body’s immune function, so the International Cancer Institute lists it as a suspected carcinogen.

Microbes, viruses, bacteria

Indoor air pollution 21% caused by microorganisms. Microorganisms and fine dust are often found in warm, humid and unclean environments. They are dispersed in the air along with dust particles, becoming a source of allergens and disease transmission. Dust mites, in particular, are an allergen to human bronchial asthma. Dust mites like to live in the dust of the room, the spring and autumn are the most vigorous period of dust mites growth and reproduction.

Kitchen fume

In the past, the pollution of indoor air by kitchen fumes was rarely taken seriously. According to research, the number of lung cancer patients in urban women has increased. Most patients diagnosed with adenocarcinoma by hospital are a case of lung cancer that has little connection with smoking. Further investigations have found that the carcinogenic pathway is associated with the mutagenicity of kitchen fumes and the oxidative decomposition of high-temperature edible oils. Another major source of pollution in the kitchen is the burning of fuel. In the case of poor ventilation, the concentration of carbon monoxide and nitrogen oxides produced by the burning appliance far exceeds the limits set by the air quality standard, and such concentration will inevitably cause harm to the human body.

Air conditioning syndrome

People who work in an air-conditioned environment for a long time often feel bored, fatigued, lethargic, muscle pain, have a high incidence of colds, and have a marked decline in work efficiency and health. These symptoms are collectively referred to as “air conditioning syndrome.” The main cause of these adverse reactions is that it stays in a confined space for too long, and the accumulation of CO2, CO, respirable particulate matter, volatile organic compounds, and some pathogenic microorganisms increases the pollution. The above various reasons have caused poor indoor air quality, causing many diseases, which in turn affects work efficiency.

Air pollution types and sources

Posted on October 21, 2019October 21, 2019 by Helen

Air pollution types and sources

First, the types of air pollutants

Air pollution is a product that has not been prevented in advance in the progress of modern civilization. It is the consequence of one or several pollutants stored in the atmosphere. The quantity and delay may damage human health.

‘Air pollutants’ are ‘materials in the air that are sufficient to directly or indirectly impair public health, or odorous substances that are sufficient to cause public dislike’. Air pollutants can be divided into two types: granular pollutants and gaseous pollutants depending on their nature:

Granular pollutants:

(1) Suspended particles: particles with a particle size below 10 microns, also known as floating dust;

(2) Metal fumigation: solid particles containing metal oxides;

(3) Dark gray to black smoke with carbon particles as the main component;

(4) Acid mist: smoke containing droplets such as sulfuric acid, nitric acid, hydrochloric acid;

(5) Dust-collecting: substances with a particle size of more than 10 microns, which can be gradually dissipated by gravity and cause public dislike;

(6) Photochemical smog: A particulate matter produced by photochemical reactions that is suspended in the air and causes visual pathological obstacles.

Gas pollutants:

(1) sulfur oxides;

(2) carbon monoxide;

(3) Nitrogen oxides;

(4) hydrocarbons;

(5) chlorine gas;

(6) Hydrogen chloride;

(7) fluoride gas;

(8) Chlorinated hydrocarbons;

(9) ammonia gas;

(10) Hydrogen sulfide;

(11) methyl sulfide;

(12) Mercaptans;

(13) methylamines;

(14) High-light chemical oxides;

(15) Formaldehyde;

(16) hydrogen cyanide;

(17) Other gaseous pollutants.

Second, the source of air pollutants

There are quite a lot of sources of air pollutants. The air pollutants produced by natural phenomena such as forest fires, swamps, plant decay, dust and volcanic eruptions are called ‘natural air pollutants’. Air pollutants produced by human activities are called ‘artificial air pollutants.’

Natural air pollutants:

(1) Forest fires produce large amounts of pollutants such as soot, unburned hydrocarbons, carbon monoxide, nitrogen oxides and ash;

(2) Produce pollutants such as methane and hydrogen sulfide in the marshes;

(3) The decay of animals and plants produces nitrogen-containing pollutants;

(4) Volcanic eruptions produce many particulate matter and gaseous pollutants such as sulfur dioxide, hydrogen sulfide, and methane.

Artificial air pollutants

(1) Industrial pollution: Contaminants that may be produced by the manufacturing process of raw materials, such as hydrogen chloride, ammonia, chlorine, lead, cadmium, particulate pollutants, etc.; burning with coal, gasoline, heavy oil, firewood, etc. Produces sulfur dioxide, nitrogen oxides, carbon monoxide, carbon dioxide, and particulate pollutants.

(2) Public facilities: such as power plants, garbage and sewage treatment facilities may also be accompanied by pollutants such as sulfur dioxide, nitrogen oxides, hydrogen chloride and odors.

(3) Personal behavior: If you use cars, household stoves, smoking, open burning of garbage branches, etc., carbon monoxide, hydrocarbons, nitrogen oxides, and particulate pollutants will be produced.

The number of premature deaths due to air pollution is 7 million per year

Posted on October 19, 2019October 19, 2019 by Helen

The number of premature deaths due to air pollution is 7 million per year

According to Futurism, air pollution is like a ‘stealth killer.’ The World Health Organization (WHO) estimates that premature deaths of 7 million people each year are related to air pollution. In the United States alone, between 7,500 and 52,000 people die each year due to exposure to tiny particulates emitted by power plants.

In fact, the latest release of the 2019 Environmental Performance Index (EPI) shows that air pollution has become the biggest environmental threat to public health.

The report was written by researchers at Yale University and Columbia University in collaboration with the World Economic Forum. It ranks 180 countries and territories using 24 performance indicators in 10 different categories, all of which are related to environmental health and ecosystem vitality. At the top of the list is Switzerland, followed by France, Denmark, Malta and Sweden. At the bottom are India, Bangladesh, Burundi, the Democratic Republic of the Congo and Nepal. The United States ranks 27th, and it scores high on sanitation and air quality, but it is very bad in deforestation and greenhouse gas emissions.

EPI shows that air pollution is the number one threat to public health. The purpose of this report is not to scare the public, but to influence the relevant policies. Daniel C. Esty, director of Yale University’s Center for Environmental Law and Policy and Professor of Yale University’s Hillhouse, said: ‘As the international community begins to pursue new sustainable development goals, policymakers need to know: in energy and the environment. Who is in the lead and who is behind.’

Esti added: ‘The EPI in 2019 confirmed that sustainable development requires economic development, generating sufficient resources to invest in environmental infrastructure, carefully managing the industrialization and urbanization processes that lead to pollution, and industrialization and urbanization threaten public health and ecology. system.’

The 2019 EPI outlines the positions of countries in terms of pollution and environmental sustainability. However, it can also reveal trends within and across countries. The lowest-ranking countries lack support for a range of sustainable development issues, and the level of air pollution is the most terrible.

These large-scale studies and reports contain a lot of things. In addition to influencing policies and assessing sustainability efforts, they also reveal efforts to address pollution. For example, a recent study showed an improvement in air pollution in the United States between 1990 and 2012. The decline in pollution is very large and it is estimated that some 180,000 deaths have been prevented.

Air pollution is directly related to early brain development, which can have serious and terrible health effects on humans. As the world’s population continues to grow, develop and build, the situation may only get worse if more intense measures are not taken. Perhaps these reports will provide the government with better tools to better protect citizens from threats.

University of Texas at Austin: Research shows that air pollution can reduce life expectancy by two years

Posted on October 19, 2019October 19, 2019 by Helen

University of Texas at Austin: Research shows that air pollution can reduce life expectancy by two years

A shocking new study finds that air pollution is reducing life expectancy worldwide. The United Kingdom and the United States have only been reduced by an average of four months, but in other countries, the situation is much more serious. For example, in the two major air pollution areas in India and Egypt, life expectancy has decreased by 1.5 years and 2 years respectively. In May of this year, WHO listed India’s capital New Delhi and the Egyptian capital Cairo as the two most polluted cities in the world.

The University of Texas Austin team responsible for the study said that the focus of previous research was on the number of deaths due to air pollution. This is the first time scientists have investigated the impact of air pollution on overall life expectancy.

The team’s main indicator is PM2.5. PM2.5 is a kind of tiny particles, mainly produced from power plants, exhaust systems, aircraft, forest fires, sandstorms and so on. Because it is too small, PM2.5 particles can be suspended in the air for a long time and are more easily inhaled by the human body. Also because of their small size, they can penetrate deep into the lungs and may even enter the human circulatory system. Studies have shown that exposure to particulate environments increases the risk of heart disease, even severe chronic diseases such as asthma and bronchitis.

According to WHO statistics, there are currently 7 million people killed worldwide due to such pollution, and most of them are distributed in low- and middle-income countries, mainly in Africa and Asia.

Using data from the Global Burden of Disease Study, the researchers examined the severity and consequences of PM2.5 air pollution in 185 countries, and then analyzed the average life expectancy of each country and the impact on global life expectancy. The results showed that the life expectancy of the United Kingdom and the United States was reduced by four months due to air pollution, but the situation in other countries was much more serious. Russia has been reduced for nine months, India for one and a half years, and Egypt has been reduced for nearly two years.

The Egyptian capital Cairo and its surrounding cities are shrouded in thick smog all year round. According to statistics from the Egyptian Ministry of the Environment, the “black cloud” accounts for about 42% of the country’s air pollution. There are many reasons for these pollutions, including automobile exhaust, burning straw, and the low greening rate in Cairo.

The picture above shows the global life expectancy reduction. The picture below shows the increase in life expectancy of the air pollution problem.

In 2017, UNEP issued a report that more than 40,000 Egyptians have died from pollution. But to calculate the number of people who die from pollution on a global scale, it takes a year to count.

‘We have long known that air pollution can kill people.’ Dr Joshua Apte, assistant professor of population health at the University of Texas at Austin, said, ‘The impact of air pollution is huge. What we are doing now is Public health is also taken into account when addressing air pollution problems. If this problem can be solved, the impact on global life expectancy may be greater than the cure for cancer and breast cancer.’

He added that scientists have studied cancer therapy more because it is easier to quantify.

‘Analying the impact of air pollution is very difficult, because you have to look at a large population, and the scale of the research is too large. But it is easy for doctors to diagnose cancer. To say that ‘this person has cancer’ is comparable to saying that this person is sick because of air pollution. ‘It’s much easier.’

Dr. Apt also added that in countries with serious pollution such as China and India, solving air dust and haze will have even greater benefits.

‘In India and China, if there is no air pollution at present, the elderly in their 60s will have greater hopes to live above 85 years old, and 15% to 20% of the opportunities will live longer. The per capita life of countries with serious pollution is even more Low, and improving air pollution will help solve this problem.’

In June, two Harvard scientists published a paper saying that Trump’s changes to environmental policy would cause the United States to die 80,000 more every 10 years.

Public health economist David Cutler and biostatistician Francesca Dominici say the ban on the Clean Power Plan (developed by the Obama administration) It is expected to cause 36,000 deaths, and the abolition of emissions from specific vehicles will result in the death of approximately 14,000 people. They pointed out that changing environmental policies will also cause more than 1 million people to suffer from respiratory diseases in the next 10 years, many of them children.

In the spring and summer seasons to deal with smog, is there any use of air purifiers?

Posted on October 16, 2019October 16, 2019 by Helen

In the spring and summer seasons to deal with smog, is there any use of air purifiers?

In the spring and summer seasons, the increasing pollution of air and respiratory health problems, such as smog, PM2.5, formaldehyde and other substances continue to emerge, and it is impossible to prevent. Wearing a mask and opening the door to open the air purifier has become a weapon for many citizens to deal with the “inside and outside repair” of the haze. However, many people still have confusion: Is there any use of air purifiers?

Questions about the use of air purifiers:

In April 2015, Tsinghua University released the “Data Analysis Report on Indoor Air Quality Survey”, saying that modern people have 80% of the time to stay indoors, and the per capita indoor PM2.5 intake is four times that of outdoor. The haze is even more serious. Studies have shown that even if the doors and windows are fully closed, if the purification method is not adopted, the indoor PM2.5 concentration is at least 1/3 of the outdoor. Proper use of air purifiers is necessary to improve indoor air quality.

How long does the purifier have to work to function?

After the purifier is turned on, there is an indoor air exchange process, which causes the larger polluted particles that originally settled on the ground to rise into the air. Indoor air pollution does not fall and rises, and this process lasts for 20-30 minutes. The contaminant concentration then decreases as the purifier’s working time increases.

Misunderstandings affecting the use of air purifiers:

Myth 1: Air purifiers are placed everywhere, not paying attention to safety

It is also undesirable for most users to place or place the air purifier directly against the wall. The placement of the wall limits air circulation and reduces work efficiency; since the air purifier first absorbs harmful substances in the air and then filters through the filter element, the filtered air is discharged.

Myth 2: Unreasonable window ventilation

I bought an air purifier, and we don’t recommend closing the doors and windows all day long. This is unscientific and not good for your health. While using the air purifier, we also need to choose the appropriate time period to open the window for air exchange. The air purifier plays the role of purification without oxygen. Especially in the newly renovated house, the air is tight and the fresh air cannot be injected.

Myth 3: I have never bought an air purifier before I bought it.

When the air purifier is used for a long time, it will absorb some substances such as dust and fluff in the air, so it should be cleaned at the air inlet, fan, etc.

Myth 4: A pair of filter cartridges took a long time

For some users, buying a purifier may be once and for all, no longer paying attention to the operation of the air purifier, which is obviously wrong. Especially for the filter element, it is necessary to pay attention to it at all times, otherwise it will not only have no effect, but also damage the purifier. Generally, the filter element is replaced once a year.

Although most of the mainstream air purifier products on the market are multi-functional, the purification technology has its own advantages. Consumers can choose different purifiers according to the purification needs of different homes, and choose the basic principle of air purifiers. Non-toxic and harmless, the second is safety, and the third is effective.
