sietorajoja

Sietorajoja, a Finnish term, translates to "tolerance limits" or "tolerance levels." It is primarily used in environmental and occupational health contexts to describe the maximum acceptable levels of a substance or condition that an organism can withstand without experiencing adverse effects. These limits are established based on scientific research and aim to protect public health and the environment.

In environmental science, sietorajoja can refer to maximum permissible concentrations of pollutants in air, water, or soil. These limits are set by regulatory bodies to prevent pollution from causing harm to ecosystems or human health. For example, limits might be set for heavy metals in drinking water or for particulate matter in ambient air.

Within occupational health, sietorajoja denote the maximum exposure levels to hazardous substances or physical agents that workers can be exposed to during their working lifetime without suffering adverse health consequences. These are often referred to as occupational exposure limits (OELs). They are determined by considering the toxicity of the substance, the duration and frequency of exposure, and the susceptibility of the exposed population. Adherence to sietorajoja in the workplace is crucial for ensuring worker safety and preventing occupational diseases. The scientific basis for setting these limits involves extensive toxicological studies and risk assessments.
