Nevertheless, the meaning of observed effects of exposures in experimental systems to human public health remains elusive.
Cohort studies designed to estimate human health effects of exposures to urban pollutants require accurate determination of ambient concentrations in order to minimize exposure misclassification errors.
Underlying these fears, he believes, are uncertainty about the effects of exposures to certain substances, a tendency to overreact and seek scapegoats in stressful situations, guilt about our affluence and an unspoken wish to return to a simpler and purer world.
Observational studies, particularly those taking advantage of resources to examine effects of exposures over several decades, remain important to study long-term exposures such as early-life influences, diet, physical, cognitive and social activities.
Scientists do not yet have a clear understanding of the health effects of exposures to these pesticide residues, although evidence suggests that children may be particularly susceptible to adverse effects.
Given concern for public health implications for potential effects of exposures transmitted to subsequent generations, it is critical to determine how widespread and robust this phenomenon is and to identify the range of exposures and possible outcomes.
The combined effects of exposures to multiple chemicals have been the subject of discussion, research, and regulation by a number of organizations for more than 50 years.
For example, our own work has demonstrated adverse effects of exposures to endocrine disruptors, particularly when exposure occurs during development -- in the fetus or child -- when our bodies are most vulnerable to environmental insults.
Rowland managed the work of scientists who assessed human health effects of exposures to pesticides like glyphosate and he chaired the EPA's Cancer Assessment Review Committee (CARC) that determined glyphosate was "not likely to be carcinogenic to humans".
Timing and intergenerational effects of exposures.
What are the effects of exposures to combinations of chemicals?
