- 15. Indirect or unintentionalImpacts • Experienced after long time when they become cumulative • Not reversible • Related to pollution and environmental degradation • Use of chemicals such as DDT, BHC, etc., • Excessive use of pesticides, fertilizers and a number of other chemicals • Example: toxic materials are transported across the placenta and reach the developing foetus of women and cause abortions and delivery of premature child
- 16. • Photochemical smog– eye irritation, respiratory problems and cancer • Acid rain – Depletes the nutrients in soil and destroy plants. Chlorosis and necrosis in plants. Irritation in the eyes and skin of human beings Affects aquatic life • Airbrone fluoride and arsenic pollution – injuries to agricultural livestocks • Green house effect – skin cancer • Ozone layer depletion – cancer • Air pollution affects weather and climate at global level
