Pollution's Harmful Impact: A Toxic Cigarette-Like Threat

Smoking and air pollution are both detrimental to human health, causing and exacerbating cardiovascular diseases and respiratory issues.

According to the World Health Organization (WHO), air pollution is the leading environmental risk factor for deaths worldwide, accounting for approximately one-ninth of all fatalities. Fine particulate matter (PM2.5) in the air has been linked to vascular effects that contribute to myocardial infarction, ischemia, strokes, and other cardiovascular diseases.

Cigarette smoke contains over 7,000 chemicals, including toxic substances like nicotine, tar, and heavy metals, as well as carcinogens. It is a major source of indoor air pollution, with secondhand smoke posing health risks to non-smokers.

Additionally, cigarette butts, which often contain plastic filters, are the most littered item globally, contributing to plastic waste and leaching toxic chemicals into the environment.

Both smoking and air pollution have short-term and long-term health effects, with vulnerable populations, including children, the elderly, and those with pre-existing health conditions, being at higher risk.

Cigarette smoke is ten times more polluting to the air than diesel emissions

The experiment involved a turbo diesel 2-litre engine being left idling for 30 minutes in the garage, with the doors closed, after which the doors were left open for four hours. The car was fuelled with low-sulphur fuel. Three filter cigarettes were then lit up sequentially, and left smouldering for a further 30 minutes. The nicotine and tar content of each cigarette was 1 mg and 11.2 mg, respectively. A portable analyser took readings every two minutes during the experiments.

The combined particulate levels in the first hour after the engine had been started measured 88 ug/m3. Those recorded in the first hour after the cigarettes had been lit measured 830 ug/m3: ten times greater. The diesel engine exhaust doubled the particulate matter levels found outdoors at its peak; the environmental tobacco smoke particulate matter reached levels 15 times those measured outdoors.

The health risks of cigarette smoke are well-known: smoking can lead to a host of diseases that affect every organ of the body, including cancer, heart disease, stroke, diabetes, lung disease and lung cancer, COPD, and more. Smoking can even be dangerous to non-smokers who experience both second-hand and third-hand smoking.

According to the World Health Organization (WHO), tobacco production’s price tag consists of ‘600,000 million trees, 200,000 hectares of land, 22 billion tonnes of water, and 84 million tonnes of CO2’.

The effects of breathing air pollution may be cumulative

Air pollution is a familiar environmental health hazard. We know what we’re looking at when brown haze settles over a city, exhaust billows across a busy highway, or a plume rises from a smokestack. Some air pollution is not seen, but its pungent smell alerts you. It is a major threat to global health and prosperity. Air pollution, in all forms, is responsible for more than 6.5 million deaths each year globally, a number that has increased over the past two decades.

Air pollution can affect lung development and is implicated in the development of emphysema, asthma, and other respiratory diseases, such as chronic obstructive pulmonary disease (COPD). Increases in asthma prevalence and severity are linked to urbanization and outdoor air pollution. Children living in low-income urban areas tend to have more asthma cases than others.

A study found that cigarette smoke is ten times more polluting to our air than diesel emissions. The constituents of cigarette smoke may be classified into two stages: tar and gas. The substance, the tar or particle phase, contains >1017 free radicals/puff that are generated from the ash of the tobacco (stream of smoke) and passed by the cigarette filter (Cambridge-fiber filter) that contains all of the suspended particulate matter (99.9%) having a particle size range > 0.1 μm. On the other hand, the gas phase is the substance that contains >1015 free radicals/puff that passes through the filter and remains active for a shorter time than the tar phase free radical. Mainstream smoke is known as cigarette smoke, which is produced from tobacco through an active smoker’s mouth. Side-stream cigarette smoke is made from the burning end of a cigarette. 8% of tar and 92% of gaseous elements are composed of mainstream cigarette smoke. Environmental tobacco smoke is primarily made up of 85 percent side-stream smoke and a small percentage of aspirated mainstream smoke from consumers. A rise in the intensity of the noxious gaseous constituent is found in side-stream cigarette smoke compared to mainstream cigarette smoke. Nicotine, which is a component of the tar phase, is the most dangerous of all the identified elements of cigarette smoke.

According to the National Toxicology Program (NTP) report, traffic-related air pollution (TRAP) exposure also increases a pregnant woman’s risk for dangerous changes in blood pressure, known as hypertensive disorders, which are a leading cause of pre-term birth, low birth weight, and maternal and fetal illness and death.

A study found that exposure to PM2.5 from coal was associated with a mortality risk that was twice as high as the risk from exposure to PM2.5 from all sources. PM2.5 from coal is high in sulfur dioxide, black carbon, and metals.

Long-term exposure to high levels of air pollution may be as harmful to the lungs as smoking

Air pollution is the leading environmental risk factor for deaths worldwide, according to the World Health Organization (WHO). Particulate matter (PM) in the air, especially PM2.5 (particulate matter with a diameter of 2.5 μm or less), has been linked to vascular effects that contribute to myocardial infarction, ischemia, strokes, and other cardiovascular diseases (CVDs). Epidemiological studies have also confirmed that cigarette smoking is the leading cause of fatal coronary artery disease and myocardial infarction.

Cigarette smoke contains over 4,000 chemical compounds, including carbon monoxide, benzene, formaldehyde, nicotine, phenol, hydrogen cyanide, polycyclic aromatic hydrocarbons (PAHs), and tobacco-specific nitrosamines (TSNAs). These compounds can be inhaled directly by the smoker (mainstream smoke) or by non-smokers (second-hand smoke).

Similarly, air pollution contains a mix of hazardous substances from human-made and natural sources, including vehicle emissions, fuel oils, natural gas, by-products of manufacturing and power generation, fumes from chemical production, smoke from wildfires, and gases from volcanic eruptions.

Both cigarette smoke and air pollution can cause serious health issues, especially to the lungs and heart. Long-term exposure to high levels of air pollution may lead to fatal coronary artery disease, just like cigarette smoking. In addition, air pollution can also increase the risk of lung cancer, asthma, chronic obstructive pulmonary disease (COPD), and other respiratory diseases.

People with heart or lung diseases such as coronary artery disease, congestive heart failure, and asthma or chronic obstructive pulmonary disease (COPD) are at increased risk

People with heart or lung diseases such as coronary artery disease, congestive heart failure, and asthma or chronic obstructive pulmonary disease (COPD) are at an increased risk of experiencing health problems due to air pollution.

Air pollution is a major threat to global health and prosperity, and it is responsible for more than 6.5 million deaths each year. It is a mix of hazardous substances from both human-made and natural sources. Vehicle emissions, fuel oils, and natural gas used to heat homes, by-products of manufacturing and power generation, and fumes from chemical production are the primary sources of human-made air pollution. Nature also releases hazardous substances into the air, such as smoke from wildfires, ash and gases from volcanic eruptions, and gases like methane.

Air pollution can affect people with heart or lung diseases in several ways. Fine particulate matter (PM 2.5) can be inhaled deeply into the lungs and cause serious health effects, such as aggravated asthma, nose and throat irritation, bronchitis, and lung damage. It can also enter the bloodstream and affect the heart. People with diabetes may also be at increased risk, as they are more likely to have underlying cardiovascular disease.

According to the National Institute of Environmental Health Sciences, air pollution exposure is associated with oxidative stress and inflammation in human cells, which may lay a foundation for chronic diseases and cancer. Exposure to air pollution has been linked to an increased risk of mortality, with exposure to the air pollutant PM2.5 being associated with an increased risk of death.

People with heart or lung diseases are particularly vulnerable to the effects of air pollution, as particles can aggravate these diseases. Exposure to air pollution has been linked to an increased risk of lung function, asthma, cardiac problems, emergency department visits, and hospital admissions. It is important to note that almost 9 out of 10 people who live in urban areas worldwide are affected by air pollution.

To protect themselves from the harmful effects of air pollution, people with heart or lung diseases should stay indoors when particulate levels are high or wear a N-95 respirator mask. They should also reduce their physical activity and limit their exposure to smoke and ash. Upgrading to a gas fireplace or installing a fireplace insert can help reduce smoke production. Additionally, it is important to keep indoor air clean by avoiding burning wood, gas logs, or even candles or incense.

Children have increased risk for several reasons: their lungs are still developing; they spend more time at high activity levels; and they are more likely to have asthma or acute respiratory diseases, which can be aggravated when particle levels are high

Children's lungs are still developing, and their exposure to air pollution can have long-term effects on their respiratory health. According to the National Institute of Environmental Health Sciences, air pollution is a mix of hazardous substances from both human-made and natural sources. Vehicle emissions, fuel oils, and natural gases used to heat homes are some examples of human-made air pollution. Wildfires and volcanic eruptions are examples of natural sources of air pollution.

Children spend more time at high activity levels, which means they breathe faster and deeper, taking more particles into their lungs. This increases their risk of inhaling harmful pollutants and developing respiratory issues. According to the World Health Organization, air pollution is the foremost environmental risk factor, accounting for roughly one-ninth of all fatalities worldwide.

Children are also more likely to have asthma or acute respiratory diseases, which can be aggravated when particle levels are high. Asthma is a condition where the airways become inflamed, narrow, and swell, making it difficult to breathe. Acute respiratory diseases are short-term infections that affect the respiratory system, such as bronchitis and pneumonia. When particle levels are high, children with these conditions may experience more severe symptoms and health issues.

Overall, children are a vulnerable group when it comes to air pollution due to their developing lungs, increased physical activity, and higher likelihood of respiratory issues. It is important to take steps to reduce their exposure to air pollution and protect their respiratory health.
