Chemistry of the environment: Fertilizers, Air and Air pollution, WRP_Avantika 13.5.22
Fertilizers:
-
-
-
E.g. Nitrogen: Ammonium Nitrate (Nitram)/ Phosphate/ Sulfate, Urea.

Eutrophication:
As we saw earlier, nitrate ions can end up in enclosed lakes and ponds. Because the concentration of nitrate ions increases, the algal life blooms. They multiply rapidly and turn the water green. As the algae die and decay, they prevent sunlight from entering the water. Oxygen is removed from the water, leaving insufficient amounts. Due to this aquatic plants and animals are destroyed, and the ecosystem is ruined.
Air:
-
First comes the troposphere, then stratosphere, mesosphere and ionosphere.
Troposphere is almost as long as 20 to 30 km and contains the maximum concentration of main gases. 75% of the mass of atmosphere comes from troposphere.
-
Air:
The air basically contains 78% of nitrogen, 21% of oxygen and other gases (pollutants, noble gases, carbon dioxide). The % composition of air depends on the place.
-
-
Atmospheric pollution:
Major pollutants:
Sulfur dioxide: Sources- Volcanic eruptions, rotting vegetation. industries, industries where sulfuric acid is produced. It is an irritant. It is toxic and used in packaging as a drying agent. It is very pungent and affects the eyes and throat. It also causes acid rains.
-
Nitrogen monoxide: Source: Industries, Causes respiratory problems and acid rains.
Carbon monoxide: It is produced when duels are burned. It affects haemoglobin; it prevents it from carrying oxygen around the body.
Lead compounds: Added to improve the efficiency of petrol. It affects your brain, nervous system and kidneys.
