Environmental tobacco smoke (ETS), also known as second-hand smoke, is a major contributor to indoor air pollution. ETS is a mixture of exhaled mainstream smoke and sidestream smoke released from smouldering tobacco products. It contains many toxic chemicals, including benzene, 1,3-butadiene, polycyclic aromatic hydrocarbons, N-nitrosamines, nicotine, and particulate matter. Exposure to ETS has been linked to adverse health effects, including respiratory issues, an increased risk of cancer, and developmental problems in children. ETS is a significant public health concern, causing illness and premature death in both smokers and nonsmokers.

What You'll Learn
Air pollution sources: human-made and natural
Air pollution is a pressing environmental health hazard. It can be seen when a brown haze settles over a city, or when exhaust billows across a busy highway. Some air pollution is invisible, but its pungent smell can be detected.
There are two main categories of air pollution sources: human-made and natural. Mobile sources, such as automobiles, account for more than half of all air pollution in the United States, according to the Environmental Protection Agency. These tailpipe emissions from cars and trucks contribute to elevated ozone concentrations. Stationary sources, like power plants, are also significant contributors, emitting large amounts of pollution from a single location. Industrial processes, such as oil and gas development, iron and steel manufacturing, and the combustion of fossil fuels, release harmful pollutants into the atmosphere.
Another human-made source of indoor air pollution is Environmental Tobacco Smoke (ETS), also known as second-hand smoke. ETS is a mixture of exhaled mainstream smoke and sidestream smoke released from smouldering tobacco products. It contains many hazardous chemicals and is a well-documented cause of illness and premature death. Research has identified around 5000 individual compounds in cigarette smoke, including 69 carcinogens.
Natural sources of air pollution, such as wildfires, can also have a significant impact. Summertime wildfires can reduce visibility and contribute to air quality issues. Wind can carry pollutants over long distances, affecting areas far from the source. Additionally, chemical reactions in the atmosphere can modify pollutants before they are deposited, creating haze and causing biological harm.
The effects of air pollution are not limited to respiratory problems but also include neurological disorders. Studies have linked air pollution to an increased risk of Alzheimer's disease, Parkinson's disease, and other dementias. The implementation of air pollution regulations and the retirement of coal-powered plants have been shown to decrease mortality rates associated with air pollution.

Health risks: respiratory issues, cancer, and more
Environmental Tobacco Smoke (ETS), or "passive smoking", has been extensively studied for its potential health effects, especially on respiratory health. ETS contains volatile substances in greater quantities than those found in mainstream smoke. These substances include benzene, 1,3-butadiene, polycyclic aromatic hydrocarbons, N-nitrosamines, nicotine, and particulate matter. These toxins are known or suspected human carcinogens and toxic agents.
ETS exposure has been linked to a range of respiratory issues, particularly the incidence, prevalence, and exacerbation of asthma. Research has focused on the association between ETS and childhood asthma, but investigations into adult-onset asthma have also been conducted. The risk of asthma prevalence is higher when both parents smoke compared to when only one parent smokes. This suggests a dose-response relationship between tobacco smoke exposure and asthma prevalence, as well as symptoms like wheezing, coughing, phlegm, and breathlessness.
ETS exposure can also lead to eye and nasal irritation in adults and may alter lung development in children, increasing the risk of various respiratory illnesses. In addition, there is a potential link between ETS exposure and lung cancer, nasal sinus cancer, and breast cancer in younger (primarily pre-menopausal) women. Cardiovascular effects of ETS exposure include heart disease mortality, acute and chronic coronary heart disease, and altered vascular properties.
Air pollution, in general, poses serious health risks, with fine particulate matter (PM2.5) being the leading cause of health problems and premature mortality. Both short- and long-term exposure to air pollution can lead to a range of diseases, including respiratory infections, stroke, heart disease, chronic obstructive pulmonary disease, and various cancers. The World Health Organization (WHO) has found links between air pollution and type 2 diabetes, obesity, systemic inflammation, Alzheimer's disease, and dementia.

Air pollution and climate change
Environmental tobacco smoke (ETS) is a major contributor to indoor air pollution. ETS, or second-hand smoke, is a mixture of exhaled mainstream smoke and sidestream smoke released from smouldering tobacco products. Research has shown that exposure to ETS can be harmful to human health, causing illness and premature death. In the United States, it is estimated that 31 million nonsmokers, including 16 million juveniles, are regularly exposed to ETS.
ETS contains many chemical species that are regulated by the US federal government as hazardous air pollutants (HAPs). These include acrolein, acetaldehyde, 1,3-butadiene, and formaldehyde. Exposure to ETS has been linked to an increased risk of respiratory tract infections, asthma, and other adverse health effects in both children and adults.
In addition to the health impacts, ETS has also been associated with developmental effects such as low birth weight, Sudden Infant Death Syndrome (SIDS), and pre-term delivery. Due to these impacts on children, ETS has been listed as an SB25 compound, which are air pollutants known to have detrimental effects on children's health.
While efforts have been made to reduce ETS exposure, such as California's comprehensive approach to smoking prevention, the indoor air pollution caused by ETS continues to pose a substantial public health threat.
To address air pollution and mitigate its effects on climate change, regulations and standards for air quality have been established. For example, the European Union (EU) has set minimum standards for air quality and national objectives to reduce overall emissions. However, as highlighted in a briefing by the European Environmental Bureau (EEB), many EU member states are failing to comply with these laws, resulting in a lack of protection for people and nature from harmful air pollution.
In conclusion, air pollution, including ETS, has significant impacts on human health and the environment. Addressing air pollution through effective regulations and policies is crucial for mitigating climate change and protecting public health.

Air quality laws and regulations
The Clean Air Act (CAA) is a comprehensive federal law that regulates all sources of air emissions, including stationary and mobile sources. The Act authorises the US Environmental Protection Agency (EPA) to establish National Ambient Air Quality Standards (NAAQS) to protect public health, the environment, and public welfare. The NAAQS specify levels of pollution deemed safe over different periods, with the six major pollutants regulated being ozone (O3), particulate matter (PM), carbon monoxide (CO), sulfur dioxide (SO2), nitrogen dioxide (NO2), and lead (Pb).
The CAA also gives the EPA the authority to limit emissions of air pollutants from sources like chemical plants, utilities, and steel mills, as well as to regulate the composition of fuels and emission-control components on motor vehicles, non-road engines, and marine engines. The EPA sets standards for "the emission of any air pollutant... which in his judgment causes, or contributes to, air pollution which may reasonably be anticipated to endanger public health or welfare". The Act also established the Prevention of Significant Deterioration (PSD) regulations, designed to prevent any significant deterioration in air quality above an established baseline level.
The Clean Air Act was first passed in 1970 and has since been amended in 1977, 1990, and 2005 (or later). The 1990 amendments were particularly focused on addressing issues such as acid rain, ground-level ozone, and stratospheric ozone depletion. The Act has been instrumental in reducing the country's air pollution, with significant reductions seen over the past few decades.
In addition to the federal Clean Air Act, individual states may have their own air pollution laws and regulations. For example, California has the California Air Pollution Control Laws (also known as the "bluebook"), which includes all relevant Health and Safety Code sections of law, as well as air pollution-related statutes from other California code books. California's 35 local air districts are responsible for creating and enforcing rules and regulations for stationary sources of air pollution.

Air pollution solutions and strategies
Air pollution is one of the most pressing environmental issues facing the world today, contributing to the climate crisis and global warming, as well as causing seven million premature deaths annually worldwide. It is therefore crucial that governments and organisations adopt strategies to reduce air pollution and improve air quality.
One strategy that has been implemented in various jurisdictions is the Emissions Trading System (ETS). ETS is a market-based mechanism that aims to reduce carbon emissions and curb air pollution. It has been shown to be effective in reducing carbon emissions per capita and can be used by policymakers to design carbon neutrality policies. The EU ETS, for example, covers the aviation sector in Europe, and the EU has also established an Innovation Fund, financed by revenues generated from the ETS, to support the aviation sector in reducing its climate impact. China has also implemented ETS pilots, which have had a significant 'reduction effect' on haze pollution concentration levels. ETS has been shown to be effective for both post-industrial and pre-industrial economies and can be used as a benchmark policy shock.
In addition to ETS, there are other strategies that can be employed to reduce air pollution. One crucial step is to adopt policies that regulate polluting industries, such as energy production, transportation, and agriculture. This includes phasing out fossil fuels, shifting to renewable energy sources, and promoting sustainable agriculture. For example, Israel has reduced water overconsumption through drip irrigation, and Australia has modified the diets of livestock to reduce agricultural methane emissions. Carbon tax systems can also be implemented as a strategy to reduce emissions and internalise environmental costs.
Furthermore, technological solutions can play a significant role in reducing air pollution. ETS Air Systems, for example, offers innovative air purification systems that remove pollutants, VOCs, and particulate matter from exhaust air, contributing to improved air quality and environmental protection.
By implementing a combination of policies, regulations, and technological solutions, significant progress can be made in reducing air pollution and improving the health and well-being of people worldwide.
