Public Access to Screening Information Data Sets (SIDS)
The Organization for Economic Cooperation and Development (OECD) is jointly investigating international high production volume (HPV) chemicals. The criteria for the selection of these HPV chemicals are production in one OECD Member country in quantities above 10,000 metric tons (22 million lbs) per annum or above 1,000 metric tons (2.2 million lbs) in two or more OECD countries. Screening Information Data Sets (SIDS) is the OECD program under which data on HPV chemicals is collected and shared. OECD member countries are working cooperatively to:
- select the chemicals to be investigated,
- collect information from government and industry files,
- complete the agreed upon Screening Information Data Set (SIDS) testing,
- make an initial assessment of the potential hazards and risks of each chemical, and
- identify the priority for additional international efforts (e.g., post-SIDS testing or exposure information gathering.
The SIDS Program involves the collection of existing test data for HPV chemicals including information on the chemical identity, physical characteristics, sources and levels of exposure, environmental fate and pathways, and ecotoxicological and toxicological data. Once the chemicals have been selected, the sponsor country collects the available data and determines whether or not additional testing is needed to complete the SIDS data set. Needed SIDS testing is conducted and the results incorporated in the SIDS dossier. A SIDS Initial Assessment Report (SIAR) is then prepared and discussed at an OECD meeting. The conclusions for this meeting represent the initial assessment conclusions of the OECD member countries concerning the chemical and the priority for additional work. Following the completion of the OECD's assessment, the chemical is referred to the U.S. Environmental Protection Agency's (EPA) risk management process to integrate the assessment into the U.S. domestic program on chemicals.
EPA's Office of Pollution Prevention and Toxics (OPPT) plays an integral role with the SIDS Program as the representative of the United States Government. OPPT is committed to making non-confidential chemical information available to the public and promoting information sharing with industry and the scientific community. As sponsoring countries complete the SIDS process for HPV chemicals, OPPT's Information Management Division (IMD) is converting the documents into electronic formats under a pilot image processing technology project to augment information sharing and provide greater accessibility to the final version of the SIDS documents. The chemical industry in the U.S. and other OECD member countries fully supports the OECD HPV work and sharing of the results because the SIDS Program avoids duplicate testing among chemical companies for fulfilling requirements of various countries.
