EPA's Pesticide Fact Sheet Database presents a comprehensive source of information on several hundred pesticides and pesticide formulations. Pesticides are quickly and easily located using keywords that describe criteria under which the pesticides can be found. On-line help screens facilitate your access of key features in the database. Reports automatically print to paper or disk files on command, putting critical information at your fingertips within seconds. The database is available on 3.5 and 5.25 diskettes and can be used on IBM or IBM-compatible equipment. DOS 2.0 or higher, 640k internal memory (RAM), and a hard drive with 5MB of available disk space are required to run the program. Twelve critical technical areas are covered in addition to the address and telephone number of an EPA contact for every chemical. These technical areas include the following: Chemical Descriptors, which include chemical name, CAS Number, synonyms and trade names, year of registration, and U.S. and foreign producers; Use Patterns and Formulations, which include application sites, methods, and rates of application; Chemical Characteristics, which includes molecular weight and formula, m.p., b. p., solubility, vapor pressure, and stability; Acute Toxicological Data, which includes LD-50 data for oral, dermal, and inhalation routes of exposure, skin and eye irritation, and sensitization; Chronic Toxicological Data, including oncogenicity, teratogenicity, mutagenicity, and reproductive effects; Physiological and Biochemical Characteristics, which includes mechanism of pesticide action, metabolism, and foliar absorption; Environmental Characteristics, which includes hydrolysis, photodegradation, aerobic and anaerobic metabolism, mobility, volatility, and bioaccumulation; Ecological Characteristics, including avian, fish, freshwater invertebrate toxicology, and honey bee acute contact toxicology; Tolerance Assessments for Agricultural Crops, including corn, wheat, and nuts; Regulatory Position and Rational Summaries; Required Labeling Regulations and Restrictions; and Major Data Gap Summaries. EPA's Pesticide Fact Sheet Database will be invaluable to environmental consultants, agriculture specialists, toxicologists, industrial hygienists, pesticide worker unions, lawyers and regulators, entomologists, ecologists, and pesticide chemists.
