Hajapäästölähteille

Hajapäästölähteille refers to diffuse sources of pollution, meaning pollution that does not originate from a single identifiable point. Unlike point sources such as a factory smokestack or a sewage pipe, diffuse sources release pollutants over a wide area. This makes them more challenging to monitor and control.

Examples of diffuse sources include agricultural runoff, which carries fertilizers, pesticides, and animal waste into water bodies. Urban stormwater runoff is another significant diffuse source, washing oil, grease, sediment, and other pollutants from roads and surfaces into rivers and lakes. Atmospheric deposition, where airborne pollutants settle onto land and water, also falls under this category.

The impact of hajapäästölähteille can be substantial. They contribute to eutrophication of water bodies, harm aquatic life, and can affect drinking water quality. Addressing these sources often requires strategies that focus on land management practices, urban planning, and public awareness campaigns rather than direct regulation of individual emitters. Efforts to mitigate diffuse pollution typically involve improving land use practices, managing urban development to reduce runoff, and implementing best management practices in agriculture and other industries.
