大宗化学品在美国排放情况排名Chemical Scorecard



     Environmental Defense and GetActive Software

     Scorecard provides detailed information on more than 11,200 chemicals, including all the chemicals used in large amounts in the United States and all the chemicals regulated under major environmental laws.

For the 650 chemicals covered by the Toxics Release Inventory (TRI) in the United States, Scorecard lets you identify which are released or managed in the greatest quantity in your area. Scorecard tracks TRI chemicals using forty different ranking criteria, allowing you to select for chemicals in a specific TRI category (e.g, air releases), health effects category (e.g., air releases of recognized carcinogens), or risk-weighted category (e.g., ozone depleting potential).

Scorecard's universe of over 6,900 chemicals includes chemicals that are produced in large volumes in the U.S., chemicals that are covered by major federal or California regulatory programs, and chemicals that have been subject to either toxicity evaluations or exposure monitoring by federal or California agencies.
Scorecard relies on the U.S. EPA's list of High Production Volume chemicals to identify the chemicals that have annual production and/or importation volumes above 1 million pounds.

Scorecard includes the chemicals that are covered by twelve federal environmental laws and five California laws.

Scorecard includes all chemicals with human health risk assessment values and most chemicals that are subject to federal or California environmental monitoring programs.

Scorecard integrates over 400 scientific and governmental databases to generate its customized profiles of local environmental quality and toxic chemicals. Since Scorecard draws all its data from authoritative sources and combines them using state-of-the-art informatics, users can be confident they are receiving credible information that reflects the best available science. All data sources are clearly cited on Scorecard, with hyperlinks back to online references whenever available. Scorecard is committed to publishing the most current environmental data available, and is regularly revised as its data sources are updated.
Currently, Scorecard's major sections acquire data from the following sources:

Scorecard's emissions and exposure information for criteria air pollutants is derived from two U.S. EPA sources: the National Emissions Trend database and the Aerometric Information Retrieval System database. The most current data available covers criteria air pollutant releases in 1999 and exposures in 2000. Scorecard will be updated to 2001 exposure data in mid 2002.

Scorecard combines exposure data from U.S. EPA's National-Scale Air Toxics Assessment with toxicity data to estimate the health risks posed by chemical pollutants in ambient air. Current data provide estimates of ambient air concentrations based on 1996 emissions data, which are generally consistent with more current monitoring data (2000). EPA's next comprehensive national-scale assessment will be based on 1999 emissions data.

Scorecard's profiles of Clean Water Act status and watershed health are derived from three U.S. EPA sources: the 1998 TMDL Tracking System, the 1999 Index of Watershed Indicators, and the 1998 National Water Quality Inventory: 1998 Report to Congress. States submitted updated information on Clean Water Act compliance status to EPA in 2000, and the National Water Quality Inventory is updated biennially for Congress (2000 update expected in 2002). EPA watershed indicator data utilize information compliled over the period 1990-1999.

Scorecard uses uses housing and demographic measures from the 1990 Census as indicators of potential lead hazards. In the absence of local data on blood lead levels in children, these indicators are generally considered by scientists and regulators to be useful for identifying potential problem areas. Other sources used to characterize lead hazards include the Centers for Disease Control's Morbidity and Mortality Weekly Report, the National Health and Nutrition Examination Survey (NHANES), and a 1998 survey of blood lead levels conducted by the Alliance to End Childhood Lead Poisoning. The updated 2000 Census data required to derive Scorecard's lead hazard indicators will become available in 2002.

Scorecard's profiles of Superfund sites are derived from multiple sources dating from 1993 to 2002. Primary sources include: NPL Fact Sheets maintained by EPA regions, and four EPA databases: the Superfund National Assessment Program (SNAP), the Comprehensive Environmental Response, Compensation, and Liability Information System (CERCLIS) database in Envirofacts; the Potentially Responsible Party (PRP) database; and the Remedial Program Managers (RPM) database. New Superfund site listings and factsheets are added to Scorecard as they are announced; EPA has not indicated when it plans to update its PRP and RPM datasets.

Scorecard combines data from the U.S. Environmental Protection Agency's Toxics Release Inventory with information on the potential health hazards of toxic chemicals. The data available on Scorecard covers chemical releases in 2000. EPA is expected to publicly release TRI data for 2001 in May 2003.

Scorecard combines livestock population data from the U.S. Department of Agriculture with waste factors developed by the agricultural community to estimate the amount of animal waste that livestock operations produce. The most current data available covers animal waste production in 1997. USDA is scheduled to update its census of agriculture in 2002.

Scorecard publishes the results of comparative risk projects that have been undertaken by local, state or federal regulatory agencies over the last decade. The dates of these priority-setting projects range from 1990 - 1999.

Scorecard integrates data from a large number of scientific and regulatory sources in its chemical profiles. Human health hazard information is compiled from over 100 separate data sources to identify recognized and suspected toxicants. Hazard rankings of chemicals are collected from five scoring systems. Chemical use information is drawn from EPA databases covering industrial uses, consumer products and pesticides. Environmental release information is drawn from the toxic chemical and criteria air pollutant sections of Scorecard. Regulatory coverage data is complied from major American environmental statutes. Information about the availablity of basic toxicity testing is derived from a 1998 EPA study of high production volume chemicals. Risk assessment values are derived from a variety of state and federal references. Scorecard's chemical profile information is updated quarterly.
