Problem Facing Environmental Health Scientist

An important problem facing environmental health scientists is arrangement the role environmental agents play in the etiology of human being disease. Assessing and predicting the actions of environmental contaminants on human health is a laborious and controversial problem. The current risk estimation persona is a four step process that involves identification of hazards, defining a dose response in animals, a mathematical judgement of risk and exposure judgment and some means of managing the risk. This paradigm has come under criticism recently because of shortcomings that relate to the overlook of consideration of human biology in the risk respectment process. The criticisms, in part, relate to inaccurate exposure assessment, lack of biologic markers, unresolved molecular mechanisms, and animal to human extrapolation. Developing sound, vicenary methods for predicting human risks requires ontogenesis accurate methods and models for assessing exposure, understanding molecular mechanisms of toxicity, and developing risk assessment models that incorporate information on mechanisms of toxicity.
The learn of chemicly induced human disease is usually undertaken in the various disciplines of industrial hygiene, toxicology, epidemiology, and risk assessment.



Scientists in these fields seldom communicate with one another, let alone with the risk assessment community. They rarely read the same journals; they usually attend diverse conferences, and are often unaware of research outside their compress field. Health professionals must deal with information from these fields to assess whether an illness is chemically induced. Because of the lack of communication between basic scientists and regulators, risk assessors are usually uninformed about the up-to-the-minute diagnostic strategies to determine whether diseases they observe are related to chemical exposures. There is a need for doctoral level scientists with throw and education in exposure assessment, epidemiology,...If you want to get a full essay, order it on our website: Orderessay
