What is the primary use of PECQs in environmental science?

The primary use of PECQs in environmental science is to assess the potential ecological risk of substances in the environment. PECQs are valuable tools that help evaluate the concentration of chemicals and their likely effects on ecosystems. By comparing the concentration of a substance in the environment to a threshold value, PECQs can indicate whether the substance is likely to pose a risk to ecological health. This method enables scientists and regulators to make informed decisions regarding environmental safety and the management of chemical substances to protect wildlife and natural habitats.
