Reference Dose and Reference Concentration Rounding in IRIS: Risk Assessment Ramifications

Lawrence V Tannenbaum

Article Type: Original Article | First Published: April 10, 2020

Commonly, reference doses and reference concentrations, toxicity factors supporting non-cancer assessments for the chemical exposures of humans, are rounded values. While the U.S. EPA's Integrated Risk Information System rather evidently employs this rounding practice so as to arrive at toxicity values that are uniform and simple in appearance, the particulars of the rounding approach are only loosely discussed. The analysis provided here found that reference dose and reference concentration rou...

Article Type: Research Article | First Published: April 09, 2020

Related some recent example of human virus diffusion and epidemiology is interesting to observe some facts related latitude, climate, air pollutants and other. In this work only few images are used to submit and hypothesis of work to better understand some process. Is interesting to observe that WUHAN is a region characterized by a specific air pollutants status and near two big river in a determinate latitude. Obviously, the human transmission and the relationship with animal transmission can n...
