Why this matters now
Noise and soil pollution — their sources, effects, standards and control — round out the pollution syllabus and feature in prelims and GS-3.
Noise pollution
Noise pollution is unwanted/excessive sound. Sources: traffic, industry, construction, loudspeakers and firecrackers. Effects: hearing loss, stress, sleep disturbance, cardiovascular and cognitive impacts, and harm to wildlife. The Noise Pollution (Regulation and Control) Rules, 2000 set ambient decibel limits for industrial, commercial, residential and silence zones (lower at night).
Soil pollution
Soil pollution is the contamination of soil with harmful substances. Sources: industrial waste, agrochemicals (pesticides/fertilisers), heavy metals, plastics, e-waste and improper waste disposal. Effects: reduced fertility, contamination of food and groundwater, and harm to soil biota and human health.
Control measures
Control of noise: standards enforcement, silence zones, sound barriers, vehicle/horn norms and awareness. Control of soil pollution: sustainable agriculture (organic/INM), proper waste management, remediation (bioremediation, phytoremediation), and afforestation to restore degraded soils.
UPSC angle
Know noise pollution sources/effects + the Noise Rules 2000 (zone-wise decibel limits, day/night), and soil pollution sources (agrochemicals, heavy metals, e-waste) and remediation (bio/phytoremediation).
