a. Infectious diseases

b. Oversupply of plant nutrient

c. Accumulation of toxic chemicals

d. Increased dissolved oxygen for marine life

Answer 2

The following are consequences of water pollution EXCEPT. d. Increased dissolved oxygen for marine life

• Water pollution may lead to many waterborne diseases like typhoid, amoebiasis, Cholera, Hepatitis A etc. Many of them prove to be life-threatening if not diagnosed early.
• Oversupply of plant nutrients in fields leads to water pollution. During the rainy season, these chemical fertilizers seep down in water bodies and cause eutrophication which leads to algal bloom.
• Accumulation of toxic chemicals takes place when effluents are discharged from industries.
• Increased dissolved oxygen for marine life is not a consequence of water pollution. Hence, option d is the correct answer.
