Edema those of a history of pulmonary problems or poor circulation also being intensified if arthritis is already present in that particular woman. Women that already have arthritic problems most often have to seek medical help for pain caused from over-reactive swelling. Edemas that occur during pregnancy are usually found in the lower part of the leg, usually from the calf down. An edema will occur in specific organs as part of inflammations, tendonitis or pancreatitis, for instance. Certain organs develop edema through tissue specific mechanisms. Examples of edema in specific organs: Six factors can contribute to the formation of edema:
Tissue residue the exposure media. In general, tissue residue approaches are used for chemicals that bioaccumulate or for bioaccumulative chemicals. The majority of these substances are organic compounds that are not easily metabolized by organisms and have long environmental persistence. Examples of these chemicals include: polychlorinated dibenzodioxins, furans, biphenyls, DDT and its metabolites, and dieldrin. The use of tissue residues in assessing toxicity and bioaccumulation may also be referred to as the tissue residue-effects approach (TRA), critical body residue (CBR) or tissue residue-based toxicity tests. Historically, aquatic toxicology toxicity tests have focused on water-based approaches where concentration of a toxicant is determined
