Why pollution is dangerous?
Pollution may muddy landscapes, poison soils and waterways, or kill plants and animals. Long-term exposure to air pollution, for example, can lead to chronic respiratory disease, lung cancer and other diseases. Toxic chemicals that accumulate in top predators can make some species unsafe to eat.
What are good air quality numbers?
Think of the AQI as a yardstick that runs from 0 to 500. The higher the AQI value, the greater the level of air pollution and the greater the health concern. For example, an AQI value of 50 or below represents good air quality, while an AQI value over 300 represents hazardous air quality.
Which of the following is most harmful pollutant?
Sulphur dioxide
