Environmental exposure scenario for reagents used in in-vitro diagnostics.

In-vitro diagnostic assays involve various substances that may be released into the environment via a sewage treatment plant if the effluent from diagnostic instruments is discharged into the drains. Because the release of liquid waste into the public sewer system is regulated at national and/or local levels, a risk assessment per site should be performed to determine whether the release of the effluent from in-vitro diagnostic equipment is compliant with applicable regulations. To facilitate the assessment, we developed a screening tool to generate exposure scenarios for chemical substances used in in-vitro diagnostic assays.
