Combining Hazard Information from Multiple Dose-Response Experiments for Benchmark Dose Estimation in Risk Assessment

Lucy Kerns

Article Type: Research Article | First Published: 2024/06/19

An important goal of risk assessment is the determination of the minimum dose levels (benchmark doses or BMDs) of a hazardous chemical at which a specified bench mark risk (BMR) is attained. In practice, more than one experiment is often conducted for a hazard to determine the BMD values. In such cases, synthesizing all available hazard information to produce an average BMD value becomes an important task for risk analysts, which can be challenging when there is significant between-experiment he...

Article Type: Research Article | First Published: December 03, 2022

Oreochromis niloticus were subjected to 30 days of α-Olefin Sulfonate sublethal toxicity test after which samples of brain, liver, and blood were collected for biochemicals evaluations. The brain under control treatment showed higher specific acetyl cholinesterase activity than the blood. Nonetheless, AChE activities in the brain and erythrocytes of O. niloticus exposed to sublethal concentration of α-OS revealed that the toxicant decreases the activities of the enzyme in both tissues, and the...
