Effects of soil pollution and its control
Short answer
Soil pollution reduces agricultural fertility and crop yields, while toxic metals enter crops. In living beings, it causes biomagnification, cancer, kidney damage, and nitrate-induced blue-baby syndrome. Controls include judicial use of fertilizers and pesticides with organic manure, and segregating, recycling waste and treating industrial effluents.
What are the effects of soil pollution on an agriculture and living beings? Write any two controls of soil pollution.
Effects of soil pollution
On agriculture: loss of fertility, reduced yield, acidic or saline soil, death of useful organisms such as earthworms and nitrogen-fixing bacteria, toxic metals taken up by crops.
On living beings: pollutants enter the food chain and are biomagnified, causing cancer, kidney and nerve damage; groundwater becomes unsafe (nitrate causes blue-baby syndrome); garbage dumps spread diseases.
Two controls
- Use fertilisers and pesticides in controlled amounts and prefer organic manure, compost and integrated pest management.
- Segregate and recycle solid waste, ban polythene, and treat industrial wastes before disposal.
