A. PREPARATION OF THE DATA ADEQUACY ASSESSMENTS

A-1. Source material used for assessment

For this unsponsored chemical, a comprehensive literature search was performed to 

identify available toxicity data for the following SIDS endpoints:

Acute toxicity to fish

Acute toxicity to Daphnia

Toxicity to aquatic plants

Acute (oral, dermal, inhalation) toxicity

Repeated-dose toxicity

Reproductive toxicity

Developmental toxicity

Gene mutation

Chromosomal aberrations

Studies relevant to non-SIDS endpoints (e.g., eye and skin irritation; neurotoxicity) conducted 

via oral, inhalation, or dermal routes were also identified through literature searching.

The following sources were searched for toxicity data:

PubMed - Bibliographic database that contains references to journal articles in the life 

sciences with a concentration on biomedicine

TOXNET -National Library of Medicine databases on toxicology, hazardous chemicals, 

environmental health, and toxic releases; includes: 

• TOXLINE with BIOSIS and NTIS;

• Development and Reproductive Toxicology File (DART);

• Chemical Carcinogenesis Research Information System (CCRIS) -

Carcinogenicity and mutagenicity test results for over 8000 

• chemicals);

• Hazardous Substances Data Bank (HSDB) - Comprehensive, peerreviewed toxicology data for about 5000 chemicals;

• Genetic Toxicology Data Bank (GENE-TOX) - Peer-reviewed genetic 

toxicology test data for over 3000 chemicals.

TSCATS - Unpublished technical reports submitted by industry to the EPA under the 

Toxic Substances Control Act]

Registry of toxic effects of chemical substances (RTECs)

Environmental Fate Database (EFDB)

ECOTOX -EPA’s peer-reviewed ecotoxicology database

EPA’s Integrated Risk Information System (IRIS) website

Agency for Toxic Substances and Disease Registry (ATSDR) website

National Toxicology Program (NTP) website

International Program on Chemical Safety Concise International Chemical Assessment 

Documents (IPCS INCHEM or CICADs)

European Chemical Substances Information System (ESIS) - source of IUCLID Datasets

Any available IUCLID Datasets found through the ESIS website and robust summaries 

submitted to EPA by former sponsors on the assigned chemicals were retrieved. Original 

sources were obtained for any relevant toxicity data found for the assigned chemicals. 

While IUCLID Datasets sometimes contained studies of interest, certain study 

descriptions contained insufficient detail to assess adequacy. In these cases, the primary source 

of the study, if available and accessible, was obtained and reviewed.

A-2. Evaluating data adequacy

Using standard OECD testing guidelines and professional judgment as guides, available 

toxicity studies for the unsponsored chemical were reviewed for adequacy. Summaries were 

prepared for all relevant data found, even if little or no study detail was available. Each study 

was summarized according to a standard format and assigned a Klimisch reliability code; all 

study summaries for the chemical were combined into a single summary document. For studies 

already assigned Klimisch codes (e.g., studies summarized in IUCLID datasets), an explanation 

was provided if the reviewer’s assessment of data adequacy differed from the pre-assigned 

Klimisch code. A table summarizing data availability/adequacy for each SIDS endpoint is 

included at the end of the summary document. 

B. SPECIFIC INFORMATION ON THE AVAILABLE TOXICITY DATA

The available data for each of the SIDS toxicity endpoints are evaluated on the following 

pages. Studies for a common endpoint are grouped together in the document and an endpoint 

adequacy assessment is provided near the top of the first page of the summaries for that 

endpoint. If the data available for the endpoint is determined to be inadequate, a basis for that 

conclusion is supplied. NOTE: If no relevant studies were identified for the chemical, only the 

data availability/adequacy summary table was completed for the report.
