Chemical pollution poses a grave threat to human health and the environment in India. Discuss the key sources contributing to pervasive chemical contamination and evaluate the effectiveness of existing environmental laws in curbing this problem.

1. Vehicular emissions → major contributors of VOCs, NOx, SOx, responsible for Delhi pollution.

2. Factory emissions and effluents → pollute the air, compromise the soil, leach into the groundwater.

3. Microplastics from single use bottles, detergents, tooth pastes etc.

4. Burning of fossil fuels to produce energy → e.g. coal based power plant → CO2, NOx, SOx etc.

5. Manufacturing processes - E.g. highly polluting leather industry of Kanpur.

→ Efficacy of Existing Regulation

1.> The Air Act, Water Act etc. establish the CPCB and SPCB to set - (i) effluent standards (ii) inspect industries etc.

2.> Regarding vehicular pollution, the governmt has brought in requirements of engines like B.S. VI and also ethanol blending of petrol.
