What animal is most affected by air pollution?
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.
How does matter affect the environment?
Environmental Impacts Of Particulate Pollution Particulate matter pollution contributes to acid rain and climate change. In addition to the worsening of acid rain, particulate pollution can also change weather patterns, cause drought, contribute to global warming, and cause the ocean to acidify.
How is human health affected by air pollution?
The health effects of air pollution are serious – one third of deaths from stroke, lung cancer and heart disease are due to air pollution. Microscopic pollutants in the air can slip past our body’s defences, penetrating deep into our respiratory and circulatory system, damaging our lungs, heart and brain.
