title: Relationship between dose and health effects.
abstract: The health effects produced by chemicals depend on the inherent toxicity of the chemical and the dose received by the exposed individual. Health effects are modified by genetic make-up, life style, nutrition, and interaction with other chemicals. In some situations it may be difficult to impossible to determine through epidemiologic studies whether exposure to chemicals (naturally occurring or synthetic) has caused harm. For all practical purposes, the risk associated with minuscule doses of most chemicals is negligible.
