Effects of Car Pollutants on the Environment

Effects of Car Pollutants

Cars, trucks, buses using fossil fuels are the largest air pollutants, it is widely known that complete traffic emits more than half of nitrogen oxides in the air. And the main reason for global warming in the World. As well as the cause of many serious illnesses.

Pollutants from cars contribute to various types of air pollution. When hydrocarbons and NOx combine with sunlight, they produce ozone. High in the atmosphere, ozone protects us from the sun’s ultraviolet rays. When holes in the ozone layer allow the ozone to approach the Earth, it contributes to the smog and causes respiratory problems.

Air pollution from cars, trucks and buses is divided into primary and secondary pollution. Primary pollution is emitted directly into the atmosphere; Secondary pollution is the result of chemical reactions between pollutants in the atmosphere. What directly affects people with chronic illnesses and newborns. The main pollutants from motor vehicles are:

  1. Particles (PM). One type of particles is soot visible in the exhaust systems of the car. Fine particles – less than one tenth of the diameter of human hair – pose a serious threat to human health, as they can penetrate deeply into the lungs. PM may be a primary pollutant or a secondary pollutant from hydrocarbons, nitrogen oxides and sulfur dioxides. Exhaust gas from diesel engines is the main contributor to PM pollution.
  2. Volatile Organic Compounds (VOCs). These pollutants react with nitrogen oxide in the presence of sunlight to form the ozone layer, the main ingredient of smog. Although useful in the upper atmosphere, this gas irritates the respiratory system at the country level, causing cough, choking and decreased lung capacity. VOCs emitted from cars, trucks and buses – which include toxic air pollutants, benzene, acetaldehyde and 1,3-butadiene – are associated with different types of cancer.
  3. Nitrogen oxides (NOx). These pollutants form the ozone layer and particles (secondary). Also, harmful as the primary pollutant, NOx can cause lung irritation and weaken body defenses against respiratory infections such as pneumonia and influenza.
  4. Carbon monoxide (CO). This odorless, colorless and toxic gas is formed by combustion of fossil fuels such as gasoline and is emitted primarily from cars and trucks. In inhalation, CO blocks oxygen from the brain, heart, and other vital organs.
  5. Sulfur dioxide (SO2). Power plants and motor vehicles create this pollutant by combustion of fuels containing sulfur, especially diesel and coal. Sulfur dioxide can react in the atmosphere to form small particles and, like other air pollutants, is the greatest health risk for young children and asthmatics.
  6. Greenhouse gases. Motor vehicles also emit pollutants, predominantly carbon dioxide, which contribute to global climate change. In fact, emissions of exhaust gases from cars, trucks and buses account for more than one fifth of the global pollution of the United States; Transport, which includes planes, trains and ships, makes up about thirty percent of all emissions of heat for heating.

Although our planet Earth suffers everyday and feels the effects of air pollutants, there are several ways in which car and truck owners can reduce the effects of car polluters on the environment. Old and badly maintained vehicles cause the greatest air pollution, but electric, hybrid and other “clean” efficient cars have a reduced impact. In addition to these well-known “clean” engines, the technology of hydrogen gas cleaning (a link to our page explaining the technology) has also greatly impacted the reduction of harmful exhaust gases, both for old and new combustion engines.

Some tips when buying a new car: check fuel economy and environmental labeling. High rating indicates low pollution levels. Increase fuel economy by driving moderately, avoiding quick acceleration and sudden braking. Keep the vehicle well maintained, with regular tire checks, and if possible, leave your car home whenever you can. Walk, use a bike or public transport whenever possible.
