environmental effects; environmental fate; physical-chemical properties if performed as described in 40 CFR
716.50; and occupational both users and non-users, general population, consumer, bystander, and environmental exposure must be submitted. Studies showing any measurable content of the High-Priority Substance in the tested substance single substances or mixture must be reported. The composition and purity of test substances must be reported if included as part of the study. Studies previously submitted to EPA pursuant to a requirement under TSCA or of the submitters own accord and studies conducted or to be conducted pursuant to a TSCA section 4 action are exempt from the submission of lists of health and safety studies required under 40
CFR 716.35 and the submission of studies required under this rule.
10 For purposes of this paragraph, the term organohalogen flame retardant includes any substances listed in paragraphd of this section under the category Organohalogen flame retardants. For any organohalogen flame retardant, all unpublished studies on health effects including toxicity studies in vivo and in vitro on carcinogenicity, reproductive and developmental effects, genotoxicity, neurotoxicity, immunotoxicity, endocrine effects, and other systemic toxicity; toxicokinetics absorption, distribution, metabolism, or elimination, including modelling studies, in humans or animals;
environmental fate; physical-chemical properties if performed as described in 40 CFR 716.50; and occupational both users and non-users, general
population, consumer, bystander, and environmental exposure must be submitted. Studies showing any measurable content of the organohalogen flame retardant in the tested substance single substances or mixture must be reported. The composition and purity of test substances must be reported if included as part of the study. Studies previously submitted to EPA pursuant to a requirement under TSCA or of the submitters own accord and studies conducted or to be conducted pursuant to a TSCA section 4 action are exempt from the submission of lists of health and safety studies requirements under 40 CFR 716.35 and the submission of studies requirements under this rule.
