To stop ozone layer depletion it should be done:
Carbons
Loss of ozone has serious effects in people because ultra-violet radiation can cause: Aging, wrinkling of the skin, and even skin cancer, eye damage (cloudy vision, cataracts).
The chemical compounds that can cause acid rain: Sulfur dioxide (802), Nitrogen oxide (NOX) and polycyclic aromatic hydrocarbons (PAH).
Acid rain occur as: Mist, fog, sleet, snow, gas and dry dust particles.
The pH of acid rain is:
Less 5 %
Acid rain is harmful because it can: Damage and kill trees, fish and other wildlife, affect human health and corroded building stone, soil and water. It dissolves nutrients and toxic heavy metals in the soil, and these are then washed into water of rivers and lakes.
The primary reason of acid rain is: Pollution in the air, which comes from burning fossil fuels such as oil and coal.
The major component of photochemical smog is: Ozone
The main physical reason of the photochemical smog is:
Temperature inverce
To prevent or reduce waste it should be done: Recycling?
Biological magnification is the process of:
Nararduus waste
