Every year, millions of pounds of toxic chemicals thought to be linked to developmental problems in fetuses and young children are released into the air. In this paper we estimate the effect of these releases on the health of newborns. Using data from the Toxic Release Inventory Program and Vital Statistics Natality and Mortality files, we find significant negative effects of prenatal exposure ...
In the field of aquatic toxicology, quantitative structure–activity relationships (QSARs) have developed as scientifically credible models for predicting the toxicity of chemicals when little or no empirical data are available. In recent years, there has been an evolution of QSAR development and application from that of a chemical-class perspective to one that is more consistent with assumption...
critical area of intervention for obstetricians, gynecologists, and other reproductive health care professionals. Patient exposure to toxic environmental chemicals and other stressors is ubiquitous, and preconception and prenatal exposure to toxic environmental agents can have a profound and lasting effect on reproductive health across the life course. Although exposure to toxic environmental c...
The purpose of this paper is to present some of the more carefully studied aspects of the preclinical toxicology of antineo-plastic agents, and apply these findings (with certain obvious cautions) to the area of environmental toxicology. Most of the studies to be described here are the result of applied toxicologic studies performed in support of the clinical introduction of new chemicals in th...
