Pollution indicators

Pollution indicators are measurements used to assess the level and impact of pollutants in the environment, such as air, water, and soil. They include specific substances like carbon dioxide, particulate matter, or heavy metals, which signal the presence and intensity of pollution. These indicators help scientists and policymakers understand pollution sources, track changes over time, and evaluate the effectiveness of regulations. Essentially, they are tools that quantify environmental contamination, guiding efforts to protect ecosystems and public health by providing a clear picture of pollution conditions.
