Absorbed Dose: In exposure assessment, the amount of a substance that penetrates an exposed organism's absorption barriers (e.g.,, skin, lung tissue, gastrointestinal tract) through physical or biological processes. The term is synonymous with internal dose. Absorption Barrier: Any of the exchange sites of the body that permit uptake of various substances at different rates (e.g., skin, lung tissue, and gastrointestinal-tract wall).

  • Social determinants of health have a strong influence on a wide diversity of health endpoints. The same is valid for the field of environmental health, as the exposure to environmental risk factors is also unequally distributed, and this unequal distribution is often related to social characteristics such as income, social status, employment and education, but also non-economic aspects such as gender, age or ethnicity. However, depending on the environmental risk and the “risk group” considered, the magnitude of inequality varies largely.

  • This is a frightening development. There are traces within you – or, depending on your circumstances and exposures, more than traces – of several hundred man-made chemicals. Many are harmless (or at least are so far thought to be). Others, however, may cause cancer and damage the nervous systems, reproductive systems, immune systems, or livers of animals. Mounting scientific evidence is confirming long-term suspicions that they do the same to human beings.
