Lake pollution

Inland seas pollution

Nature

Lake pollution is the contamination of lake water by harmful substances, including chemicals, waste, and microorganisms. This environmental problem results from human activities such as industrial discharge, agricultural runoff, sewage disposal, and littering. Pollutants degrade water quality, disrupt aquatic ecosystems, and threaten the health of plants, animals, and humans. Lake pollution can cause algal blooms, oxygen depletion, and loss of biodiversity. It also reduces the recreational and economic value of lakes. Addressing lake pollution requires effective waste management, pollution control measures, and public awareness to protect these vital freshwater resources for current and future generations.

Incidence

During the Soviet period, two main rivers feeding the Aral Sea, Amu Darya and the Syr Darya, became contaminated with the pesticides and other chemicals that were being sprayed on cotton and rice fields they irrigated. These chemicals settled on the Aral seabed, and now that much of the sea has evaporated, windstorms carry the chemicals to the cities and villages hundreds of kilometers beyond. Dust storms pollute the air people breathe and the water they drink. Very high incidence of anemia, especially among children, was reported in 1997. Cancers increased. Stomach and intestinal diseases became very common.
