Air pollution is all around us. Air pollution causes both short-term and long-term effects on the respiratory tract. 2. The UNECE Convention on Long-range Transboundary Air Pollution has also provided threshold (critical) levels for ozone (O3), above which, impacts on crops and other vegetation can occur. One of the most common sources of air pollution in rural and peri-urban areas of low-income countries, comes from households burning biomass, other solid fuels (e.g. Some crops are very sensitive to O3, especially beans. Air Pollution Perception (1/2) Question Title * 1. A: "Acid rain" is a broad term used to describe several ways that acids fall out of the atmosphere. 4.
