C. Waste gases:
- CO is the product not completely burned, carbon (C), 80% Co is from motor cars, motorcycles, activities of other explosive devices, flue tiles, fireplace stoves, volcanic eruptions ... CO on animal body, endangering people by CO combines with hemoglobin oxygen do not absorb blood, obstructing breathing. In soil carbon absorbed part of the soil colloids, partially oxidized to CO2.
- Enters the atmosphere SO2 SO4 transformed into acid pollutants spread in the soil environment
- Lead dust in waste gases from industrial activities (mainly transport), settled down and contaminate soil accumulation.
- nitrogen oxides generated from the nitrogen in the air due to the operation of transportation, due to the microorganisms in the soil, composting activity straw man. Large amounts of nitrogen oxides accumulate in plants affect humans
So CO2, SO2, NO2 in air pollution that causes acid rain, increased soil acidification process.
D. Waste and organic chemistry:
The waste can cause soil pollution to a large extent, such as detergents, fertilizers, plant protection agents, dyes, paints, industrial production of batteries, under leather, industrial chemical production.
Many organic wastes also leads to soil contamination. Many juices from city sewers often used as irrigation water for agricultural production. In such wastewater often including waste water and industrial, should usually contain heavy metals.
