The regulatory level for benzene under the RCRA Toxicity Characteristic rule is?

The regulatory level for benzene under the Resource Conservation and Recovery Act (RCRA) Toxicity Characteristic rule is established at 0.5 mg/L. This means that if the concentration of benzene in a waste sample is at or above this level, the waste is considered hazardous under RCRA regulations.

This standard is based on benzene's known toxic properties and potential to pose significant health risks, including carcinogenic effects. The Toxicity Characteristic rule is designed to ensure that hazardous wastes do not pose a risk to human health and the environment when they are disposed of.

The other concentrations listed do not meet the established regulatory level for benzene according to the RCRA standards, as they either fall below the threshold or represent different types of measurements. Understanding these regulatory levels is crucial for environmental health specialists and sanitarians when assessing waste management practices and ensuring compliance with environmental regulations.
