põlevuslimiidid

Põlevasujaid is a significant issue in Estonia, particularly in the coastal regions. In Estonian, põlevasujad are known as põlevasujad or simply põlemistingid, meaning "burning fires" or " combustion substances".

Põlevasujad refer to certain types of inorganic combustion residues found in the soil and marine environment. These residues consist of a variety of long-lived and highly toxic particles that originate from the combustion of fossil fuels, primarily oil shale. Oil shale is a combustible sedimentary rock that has been mined and burned in Estonia for many decades, leading to the accumulation of these residues.

The prolonged presence of põlevasujad in the environment has been linked to a range of ecological and health problems. These include reduced plant growth and increased biodiversity, cancers, and reproductive issues among local wildlife. Studies have also detected the presence of these residues in marine organisms, demonstrating the risks to human health through the food chain.

Estonian authorities have implemented measures to mitigate the effects of these residues. Strategies include the generation of methods to reduce the emissions, the establish of soil contamination hotspots, and soil remediation. Government and scientific institutions collaborate to monitor the levels of põlevasujad and to develop early warning systems.

Information from various science organizations and research papers indicates that the extent of the environmental problems is widespread. Approximately 27% of Estonia's territory, including swamp and bog areas, is polluted by põlevasujad. These have transboundary implications for the shelf and aquatic ecosystem of the surrounding waters of other European and Scandinavian countries. Those contaminated with põlevasujad have linked to long-term environmental degradation and climate change, necessitating thorough remediation efforts.
