WEB resources for pesticide toxicology, environmental chemistry, and policy: a utilitarian perspective.

Information about pesticides has grown exponentially over the last four decades and is marked by a diversity of sources including government, universities, environmental advocates, and industry. The internet has made access to this unprecedented amount of information faster than ever, but judging the validity and usefulness of the information is problematic. To avoid turning this discussion of web resources for pesticide information into a narrative about a personal 'top ten' list, a utilitarian perspective of resources useful to a research, educator, and risk communicator is elucidated. Useful web sites are fit into the context of information needed for risk assessment, which includes hazard identification, dose-response relationships, exposure assessment, and risk characterization. In addition resources for pesticide policy and regulations are considered. Specific ways in which the sites are useful are discussed along with information about site updating and validation of information.
