Download or read book Human Variability in Response to Chemical Exposures written by David A. Neumann and published by International Life Science Inst. This book was released on 1998 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: and for those interested in toxic effects of chemicals on humans, Human Variability in Response to Chemical Exposures: Measures, Modeling, & Risk Assessment recognizes & addresses the increasing awareness that individual biological differences be reflected when assessing human health risks associated with exposure to chemicals. Eight original manuscripts, commissioned by the ILSI Risk Science Institute, address the evidence for variability in human response to chemicals associated with reproductive & developmental effects, effects on the nervous system & lungs, & cancer. Their reports convey both the current state of scientific understanding of response variability & the genetic basis for such observations. This book recognizes that understanding of variability in response is critical in accounting for interindividual variability in susceptibility and, hence, risk, if the regulatory community & others are expected to characterize human health risks associated with exposure to chemicals. Models for incorporating measures of response variability in the risk assessment process are critically reviewed & illustrated with published data. This authoritative work indicates that, in the case of certain chemicals & in the context of certain specific toxic effects, we have considerable ability to predictively & quantitatively characterize human variability, but, in the majority of cases, our ability to do so is limited. If we improve both quantity & quality of information available on response variability & increase our understanding of target tissue dosimetry, we should be better able to account for variability in human susceptibility to the toxic effects of chemicals.
