A '''Screeningscreening Informationinformation Datasetdataset''' (SIDSSID) is a study of the [[Chemical safety|hazards]] associated with a particular [[chemical substance]] or group of related substances, prepared under the auspices of the [[Organisation for Economic Co-operation and Development]] (OECD).<ref>Organisation for Economic Co-operation and Development [http://webdomino1.oecd.org/horizontal/oecdacts.nsf/linkto/C%2890%29163 Decision-Recommendation of the Council on the Co-operative Investigation and Risk Reduction of Existing Chemicals] C(90)163/Final, 31 January 1991.</ref> The substances studied are [[High Production Volume Chemicals|Highhigh Productionproduction Volumevolume (HPV) chemicals]], that is chemicals which are manufactured or imported in quantities of more than 1000 tonnes per year for any single OECD market.
The list of HPV chemicals is prepared by the OECD Secretariat and updated regularly. As of 2004, there were 48434,843 chemicals were on the list.<ref>{{citation | author = OECD Secretariat | title = The 2004 OECD List of High Production Volume Chemicals | url = http://www.oecd.org/dataoecd/55/38/33883530.pdf | publisher = Organisation for Economic Co-operation and Development | ___location = Paris | date = 2004}}.</ref> Of these, roughly 1000 have been prioritised for special attention, and itSIDs isare prepared for these chemicals that SIDS are prepared,<ref name="descrip">{{citation | title = Description of OECD Work on Investigation of High Production Volume Chemicals | url = http://www.oecd.org/document/21/0,3343,en_2649_34379_1939669_1_1_1_1,00.html | publisher = Organisation for Economic Co-operation and Development | date = December 2005 | accessdate = 2009-08-26}}.</ref> usually by an official agency in one of the OECD member countries with the collaboration of the [[United Nations|UN]] [[International Programme on Chemical Safety]] (IPCS).
The procedures for investigating the risks of an HPV chemical are described in the OECD ''Manual for Investigation of HPV Chemicals''.<ref>{{citation | author = OECD Secretariat | title = Manual for Investigation of HPV Chemicals | url = http://www.oecd.org/document/7/0,3343,en_2649_34379_1947463_1_1_1_1,00.html | publisher = Organisation for Economic Co-operation and Development | ___location = Paris | date = July 2007}}.</ref> The initial stage is the collection of existing information (either published or supplied by manufacturers) on the chemical. If the existing information is insufficient to make an assessment of the risks, the chemical may be tested at this stage to collect more data. The initial report of the investigation is discussed at a SIDSSID Initialinitial Assessmentassessment Meetingmeeting (SIAM), which includes:<ref name="descrip"/>
*representatives of OECD member countries;
*experts nominated by the IPCS, the OECD Business and Industry Advisory Committee (BIAC), Trade Union Advisory Committee (TUAC), and environmental organizations;
* representatives of companies which produce the chemical;
* secretariat staff from OECD, IPCS, and UNEP Chemicals.chemicals
The SIAM can either accept the draft report or call for revisions (including further testing). Once the comments and discussion of the SIAM have been taken into account, the report is published by the [[United Nations Environment Programme]] (UNEP).
The possibility of new testing to complete the study is what distinguishes SIDSSID reports from similar studies such as [[Concise International Chemical Assessment Document]]s (CICADs). In this sense, SIDSSIDs are similar to [[European Union Risk Assessment Report]]s (RARs). The distinction is that the SIDSSIS programme is specifically aimed at HPV chemicals, while the chemicals selected for EU RARs are chosen more on the basis of a hazard profile and, so include chemicals with much lower production volumes.
