The development of welding fumes health risk assessment tool for automotive component related industries
… limited. Currently, the welding fume exposure risk assessments are largely focused on a single welding fume constituent approach because the regulatory standard for compliance only caters for a single constituent. However, in reality, welders are simultaneously exposed to multiple welding fume …

Theoretical Considerations in the Estimation of the Signal-to-Noise Crossover Dose
A goal of health risk assessment is the determination of the reference dose. The estimation of the point of departure plays an important role in the derivation of the reference dose. The method of benchmark dose has been widely employed in the determination of the point of departure. However, due …
