Air, water, soil, and food are all possible exposure sources or mediums in which people can come in contact with chemicals. The Sapphire Group’s consultants possess the special skills required to determine the doses relevant to health. We are able to integrate doses for multiple exposure sources (media) to ascertain any possible health significance. To illustrate, a person might be exposed to a substance in water while consuming soup, bathing, inhaling vapors while making coffee, and then again at the workplace. Critical as this matter is, it is not the source of exposure but the nature and magnitude of the exposure to humans and other biota.
