Explanation:
Effects of air pollution (Pollutants) on living organisms
Air pollution is harmful to human beings and other living things. About 22 million people die from air pollution each year. Breathing polluted air increases the risk of developing lung diseases such as asthma and lung cancer. Breathing bad air also increases the chances of dying from other diseases. Children are most likely to be affected by air pollution. That’s because their lungs are still developing and growing. Children also take in more air for their size than adults do. Some air pollutants damage the environment as well as the health of living things. The type of damage depends on the pollutant. Air pollution can also harm the environment.
Types of Pollutants
The effects of different pollutants on the environment and human health. The pollutants include particulates, ozone, nitrogen oxides, sulfur oxides, carbon monoxide, heavy metals, and VOCs(Volatile Organic compounds).
Particulates
Particulates cause lung diseases. They can also increase the risk of heart disease and the number of asthma attacks. Particulates block sunlight from reaching Earth’s surface. This means there is less energy for photosynthesis. Less photosynthesis means that plants and phytoplankton produce less food. This affects whole ecosystems.
Ozone
The ozone in smog may damage plants. The effects of ozone add up over time. Plants such as trees, which normally live a long time, are most affected. Entire forests may die out if ozone levels are very high. Other plants, including crop plants, may also be damaged by ozone. Below, you can see evidence of ozone damage
Nitrogen and Sulfur Oxides
Both nitrogen and sulfur oxides are toxic to humans. These compounds can cause lung diseases or make them worse. Nitrogen and sulfur oxides form acid rain, which is described in the next concept.
Carbon Monoxide
Carbon monoxide (CO) is toxic to both plants and animals. CO is deadly to people in a confined space, such as a closed home. Carbon monoxide is odorless and colorless, so people can’t tell when they are breathing it. That’s why homes should have carbon monoxide detectors.
Heavy Metals
Heavy metals, such as mercury and lead, are toxic to living things. They can enter food chains from the atmosphere. The metals build up in the tissues of organisms by bioaccumulation. Heavy metals accumulate as they are passed up a food chain. Imagine a low-level consumer eating a producer. That consumer takes in all of the heavy metals from all of the producers that it eats. Then a higher-level consumer eats the low-level consumer.
VOCs
VOCs are toxic to humans and other living things. In people, they can cause a wide range of problems. These can range from eye and nose irritation to brain damage and cancer. Levels of VOCs are often higher indoors than out. That’s because they are released by products such as paints, cleaning solutions, and building materials.
Summary
An increase in particulates may have these effects. It may reduce photosynthesis, increase precipitation, and reduce temperatures.
Ozone may damage native plants and some crop plants. Ozone may slow plant growth or damage leaves.
Pollutants emitted into the air cause lung and other diseases in humans.
