Types of Environmental Pollution - JSS2 Physical and health education Lesson Note

Environmental pollution is the contamination of the natural environment, which causes adverse changes. Here are the main types:

 

Air Pollution

Sources: Emissions from vehicles, factories, and burning of fossil fuels.

Effects: Respiratory problems, global warming, acid rain, and smog.

Water Pollution

Sources: Industrial waste, sewage, oil spills, and agricultural runoff.

Effects: Contaminated drinking water, destruction of aquatic ecosystems, and health hazards for humans and animals.

Soil Pollution

Sources: Use of pesticides and fertilizers, industrial waste, and deforestation.

Effects: Loss of soil fertility, contamination of food crops, and health risks from consuming polluted produce.

Noise Pollution

Sources: Traffic, industrial activities, construction, and loud music.

Effects: Hearing loss, stress, sleep disturbances, and wildlife disruption.

Light Pollution

Sources: Excessive or misdirected artificial light from streetlights, buildings, and billboards.

Effects: Disruption of ecosystems, interference with astronomical observations, and health problems like sleep disorders.

Radioactive Pollution

Sources: Nuclear power plants, improper disposal of radioactive waste, and accidents like Chernobyl.

Effects: Cancer, genetic mutations, and environmental contamination for thousands of years.

Thermal Pollution

Sources: Industrial processes and power plants discharging hot water or chemicals into water bodies.

Effects: Disruption of aquatic life, reduced oxygen levels in water, and alteration of ecosystems.
