• endrcrine disrupter

http://www.epa.gov/endocrine/ This is a research initiative site. The EPA is previewing a number of classes of chemicals suspected of causing endocrine disruption. Even thuogh there is a lot of information reguarding endocrine disruptors, many scientific uncertainties still remain. In 1996 the EPA Office of Research and Development [ORD] identified endocrine disruptors as one of its top six research properties and developed a risked based research approach to adress some of these uncertainties.

• ecotoxicology

http://www.imprc.com/expert/ecotox/index.shtml This resource is an overview of Ecotoxicology in Pest Management. It is both a basic guide to the subject and an information resource for scientists, policy makers and commercial companies on who is doing what, and where in Ecotoxicology.

• ecological risk assessment

http://www.environment-agengy.gov.uk/yourenv/consultations/607183/?version=1&lang=_e

This web site explains what an Ecological Risk Assesment is a framework and methods for assesing harm to ecosystems from contaminants in soil. The EPA invited anyone with expertise in performing Environmental Risk Assesments [ERA's] to take part in a public consultation on a proposed framework and methods for assesing how chemical contaminants in the siol pose rishs to ecosystems.

• bioaccumulation

http://toxics.usgs.gov/definitions/bioaccumulation.htm This is a Toxic Substances Hydrology Program site. This site explains that bioaccumulations is a general term for the accumulation og substances, such as pesticides [an example is methylmercury or other organic chemicals in in an organism or part of an organism. The accumulation process involves biological sequestering of substances that enter the organism through respiration, food intake, epidermal [skin] contact with the substance, and/or other means.

• emerging disease

http://www.medicalcenter.osu.edu/patientcare/healthinformation/otherhealthtopics/Travelmedicine/EmergingInfectiousDisease5082/ This web site is The Ohio State University Medical Center. This site states according to the National Institute of Allergy and Infectious Diseases, emerging infectious diseases are commonly defined as: diseases that have newly appeared in a population and diseases that have existed in the past but are rapidly increasing in incidence of geographic range. It goes on to explain in detail more about emerging diseases and what the risks are, and travel-related infectious diseases on the rise and how travelers can minimize their risks from these diseases.

• pollution

http://www.epa.gov/air/ This is the Office of Air and Radiation. It tells what the EPA plans to do or has done to prevent pollution. Examples are that the EPA removed Methyl Ethyl Ketone from the list of Toxic Air Pollutants after extensive Analysis, Proposing to reduce air toxics risks from Dry Cleaners. The EPA also celebrates the Nation's Cleaner Environment on its 35th anniversary.
