1 A. PREPARATION OF THE DATA ADEQUACY ASSESSMENTS

A

- 1. Source material used for assessment

For this unsponso red 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

Repea ted

- 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 identifie d through literature searching.

The following sources were searched for toxicity data:

PubMed

- B ibliographic database that contains references to journal articles in the life

sciences with a concentration on biomedicine

T OXNET

- N ational L ibrary of M edi cine 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)

-

Carci nogenicity and mutagenicity test results for over 8000

**•** Hazardous Substances Data Bank (HSDB)

- Comprehensive, peer

reviewed toxicology data for about 5000 chemicals ;

**•** Genetic Toxicology Data Bank (GENE

toxicology test data for over 3000 chemicals.

- source of IUCLID Datasets

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

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

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

While IUCLID D ataset s 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 obtain ed and review ed.

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 assign ed 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 ass essment 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 comp leted for the report
