How does car exhaust affect the air?
A car’s exhaust emits hydrocarbons, a toxic compound of hydrogen and carbon. When fuel burns, nitrogen and oxygen react with each other and form nitrogen oxides (NOx). Particulate matter — small particles of foreign substances — in the air contribute to atmospheric haze and can damage people’s lungs.
What are the harmful effects of vehicle emission?
Motor vehicle emissions contribute to ambient levels of air toxics known or suspected as human or animal carcinogens. Exposures to air toxics can also cause noncancerous health effects, such as neurological, cardiovascular, respiratory, reproductive and/or immune system damage.
What are the effects of emissions?
Abstract: Air pollutants are responsible for a number of adverse environmental effects, such as photochemical smog, acid rain, death of forests, or reduced atmospheric visibility. Emissions of greenhouse gases from combustion of fossil fuels are associated with the global warming of Earth’s climate.
What is the effect of such emission to the human health?
Exposure to high levels of air pollution can cause a variety of adverse health outcomes. It increases the risk of respiratory infections, heart disease and lung cancer. Both short and long term exposure to air pollutants have been associated with health impacts. More severe impacts affect people who are already ill.
What are the major effects of particulate matter on environment and human health?
Health Effects Exposure to such particles can affect both your lungs and your heart. Numerous scientific studies have linked particle pollution exposure to a variety of problems, including: premature death in people with heart or lung disease. nonfatal heart attacks.
What are the effects of particulate matter on the environment?
When particulate pollution is heavy in an area, it can have a huge impact on forests, wildlife and coastal regions. It’s common to find large patches of dying trees in forests affected by PM. The groundwater becomes too acidic, and vital nutrients are leached out of the soil, which prevents the trees from growing.
What are the effects of lead on the environment?
Lead released into the environment makes its way into the air, soils, and water. Lead can remain in the environment as dust indefinitely. The lead in fuels contribute to air pollution, especially in urban areas.
What is the biggest water pollutant?
Every year, over 2 billion pounds of pollutants are dumped into our waterways by power plants – the largest source of toxic water pollution in our country. This wastewater contains heavy metals and chemicals known to harm human health, like lead, mercury and arsenic.
