Risk Assessment and Industrial Chemical.

General information:

Canada’s Existing Substances Assessment Repository (CESAR) contains risk and other regulatory assessment reports on existing chemicals which include individual substances, groups or classes of chemicals, or effluents or wastes that are produced or imported in Canada or released into the Canadian environment. Under Canada’s Canadian Environmental Protection Act (CEPA), these assessments are aimed at determining whether or not these substances present or may present a risk to the environment and/or human health in a Canadian context. The assessments thus address common environmental and human health endpoints under four main themes: 1) the substance identity 2) the entry, fate and exposure characterization, 3) the effects characterization and 4) the risk characterization. A weight-of-evidence approach and precaution are applied throughout the assessment process. The risk assessment program under CEPA is conducted in collaboration by both Environment Canada and Health Canada. Assessments found within this repository are generally from two major initiatives from Canada: the Chemicals Management Plan, including the Challenge, as well as the Priority Substances List (PSL) Assessment Program. For more details about these two initiatives, please visit: https://www.canada.ca/en/health-canada/services/chemical-substances.html.

The risk and other regulatory assessments of existing chemicals in CESAR are useful to a diversity of audiences, including hazard assessors (in governments, industry or health organisations), educators, health and medical professionals, and the general public.

General information:

The Joint Substance Data Pool of the German Federal Government and Federal States (GSBL) is now called ChemInfo.

The Information System on Chemicals of the German Federal Government and the German Federal States (ChemInfo), formerly known as the Joint Substance Data Pool of the German Federal Government and Federal States (GSBL) is a continuously maintained, uniform collection of validated information on chemical substances. The mission of the cooperation is to provide public authorities (e.g., police, fire brigades, governmental authorities, etc.) and the general public with reliable, topical chemicals information in support of all activities to prevent and avert danger and to protect humans and the environment.

ChemInfo comprises a wide range of features of chemical substances. Records contain information on physical and chemical properties, on ecotoxicological and toxicological parameters and on environmental fate. They provide descriptions of environmental hazards, health dangers, fire and other technical hazards and give information on relevant chemicals-related legislation.

The information contained is partly elaborated directly for the ChemInfo database by utilising the cooperation’s own resources and partly obtained from numerous external suppliers (BAuA, BAM, RESY, BIG, GDL, ETOX, RIGOLETTO, et al.). The current version contains information on some 51,000 pure substances, 26,000 component substances (mixtures and preparations) and substance-related information on 226 relevant German and European legislation.

Hazard assessments.

General information:

The database includes a variety of studies where chemicals are grouped together for a risk assessment that is usually limited to one or a few human health or environmental endpoint(s). The risk assessment may be very succinct (e.g. including threshold of toxicological concerns only for the hazard part of the assessment) or fully detailed (e.g. including robust study summaries). The database does not contain the studies itself but will point users to links where the studies are available. These links may be from regulatory agencies or other intergovernmental. The database should be useful for the dissemination of studies of combined exposures to multiple chemicals as this is an emerging regulatory issue.

The list of studies and chemicals included can be found on this page.

General information:

The aquatic life benchmarks (for freshwater species) provided are based on toxicity values reviewed by the U.S. Environmental Protection Agency (EPA) and used in the Agency's most recent risk assessments developed as part of the decision-making process for pesticide registration. Each Aquatic Life Benchmark is based on the most sensitive, scientifically acceptable toxicity endpoint available to EPA for a given taxon (for example, freshwater fish) of all scientifically acceptable toxicity data available to EPA.  Acute and chronic benchmarks are developed for freshwater fish and invertebrates and for aquatic vascular and nonvascular plants.  Each of the chemical benchmarks is linked to the EPA ecological risk assessment chapter from which they were used.  These aquatic benchmarks are extracted from the most recent publically available OPP risk assessment for the pesticide and are based on the most sensitive aquatic toxicity data of the distribution for each taxa. Benchmarks, developed for baseline risk assessments, are estimates of the concentrations below which pesticides are not expected to harm aquatic life. Comparing a measured concentration of a pesticide in water with an aquatic life benchmark can be helpful in interpreting monitoring data, and to identify and prioritize sites and pesticides that may require further investigation.

IPCheM is a single access point for locating and accessing chemical monitoring data across all media in the European Union. Operated by the European Commission in collaboration with some European Union Agencies, it is developed to address the lack of information on the chemical exposure and burden on the humans and the environment, recognised as the major gap in the knowledge base for chemical policies in several policy documents in the past 15 years. IPCheM is not a database but a decentralised system providing remote access to existing chemical monitoring data and information systems: while providers maintain the structure of their databases, the provision of data therein is harmonised in order to be accessible, retrievable and comparable through a unique interface. This creates greater visibility and promotes a wider use of valuable chemical monitoring data, thus increasing the knowledge base for sound risk assessment, management and communication. Combining information and chemical data from different sources on a variety of environmental media, consumer products and food, and ultimately from human beings themselves, provides the basis for better understanding the effects of exposure to chemical mixtures.

General information:

EPA’s Integrated Risk Information System (IRIS) is a human health assessment program that evaluates quantitative and qualitative risk information on effects that may result from exposure to environmental contaminants. IRIS was initially developed for EPA staff in response to a growing demand for consistent information on substances for use in risk assessments, decision-making, and regulatory activities. The information in IRIS is intended for those without extensive training in toxicology, but with some knowledge of health sciences. Please see: https://www.epa.gov/iris/basic-information-about-integrated-risk-information-system for more information.

General information:

The Substance Registry Services (SRS) is the Environmental Protection Agency's (EPA) central system for information about regulated and monitored substances. It is the portal for discovering chemical information at EPA. The system provides a common basis for identification of chemicals, biological organisms, and other substances listed in EPA regulations and data systems, as well as substances of interest from other sources, such as publications.

For each chemical, the SRS provides basic core metadata, including Chemical Abstract Service (CAS) names and CAS numbers. SRS identifies an EPA standardized name for each chemical (e.g., “Toluene” for the chemical with CAS name “Benzene, methyl-”). SRS also includes the molecular weights, molecular formulae, former CAS numbers and descriptions (when available).

A second section of each SRS substance record provides statutory or list information on each chemical. For each US environmental statute, the SRS identifies the list of chemicals named on that statute and the synonym used. For each US EPA data system, the SRS identifies the list of chemicals in that data system and the synonym used. The SRS also has chemical lists for external organizations, such as lists maintained by other US federal agencies or lists maintained by international organizations.

A third section provides links, if available, from the SRS to other sites for additional information. These links might be to other substance registry systems, such as those managed by other federal agencies or international organizations, or to fact sheets about the chemical.
