Endocrine Disrupter
http://www.greenfacts.org/endocrine-disruptors/endocrine-disrupter.htm
Endocrine Disrupter (EDC) refers to a chemicals, either natural and man-made, which can interfere with the endocrine system, its hormones or where the hormones act. In many cases, it is not yet clear exactly how an Endocrine Disrupters acts, even in some cases where a link has been shown between Endocrine Disrupter exposure and an adverse effect.
Ecotoxicology
The ECOTOX (ECOTOXicology) database provides single chemical toxicity information for aquatic and terrestrial life. ECOTOX is a useful tool for examining impacts of chemicals on the environment. Peer-reviewed literature is the primary source of information encoded in the database. Pertinent information on the species, chemical, test methods, and results presented by the author(s) are abstracted and entered into the database.
Ecological Risk Assessment
http://www.epa.gov/pesticides/ecosystem/ecorisk.htm
EPA conducts ecological risk assessments to determine what risks are posed by a pesticide and whether changes to the use or proposed use are necessary to protect the environment.
Bioaccumulation
http://www.ccny.cuny.edu/social_science/Kfoster/eep/people/bioaccum.htm
Bioaccumulation is a process by which the concentration of a chemical increase over time in a biological organism compared to the chemical's concentration in the environment. Compounds accumulate in living things any time they are taken up and stored faster than they are broken down (metabolized) or excreted.
Emerging Disease

Emerging Infectious diseases that may be transmitted between animals and humans are a concern for all people, no matter what their age, gender, lifestyle, ethnic background, or economic status.
Pollution
http://www.worldbank.org/nipr/
A site for researchers, government officials, and citizens interested in understanding and improving control of industrial pollution, especially in developing countries. NIPR is the primary source for materials produced by the World Bank's Economics of Industrial Pollution Control Research Project.
Biological Magnificaiton
http://www.mhhe.com/biosci/esp/2001_gbio/folder_structure/ec/m3/s4/
Biological magnification (or biomagnification) is the buildup of certain substances, such as DDT, in the bodies of organisms at higher trophic levels of food webs. DDT was once used extensively as an insecticide. DDT builds up in the fatty tissues of organisms. Organisms at lower trophic levels accumulate small amounts. Organisms at the next higher level eat many of these lower-level organisms and hence accumulate larger amounts. At the highest trophic levels the increased concentrations in tissues may become toxic.
Carcinogen
http://en.wikipedia.org/wiki/Carcinogen
In pathology, a carcinogen is any substance or agent that promotes cancer. Carcinogens are also often, but not necessarily, mutagens or teratogens.
Red Tides

Red tides can often have a devastating effect on fisheries is some coastal areas. Red tides are caused by several species of microscopic plants called phytoplankton. These species produce strong chemical toxins poisons called toxins.
