California’s Office of Environmental Health Hazard Assessment (OEHHA) has requested information and data on the reproductive toxicity hazards posed by four chemicals.
The information request will enable the agency to prepare hazard identification materials. These materials will be used to determine whether the chemicals meet the criteria to be listed under Proposition 65.
The chemicals are:
perfluorooctanoic acid (PFOA) and its salts;
perfluorooctane sulfonate (PFOS) and its salts; and
nickel and nickel compounds.
The selection of the chemicals was made at the November 2015 meeting of the state’s Developmental and Reproductive Toxicant Identification Committee (DART-IC). The committee established a “high” prioritization level for PFOA and PFOS and a “medium/low” priority for nickel.
The DART-IC –advises the OEHHA on determining the reproductive toxicity of chemicals and substances. The committee also suggested that n-hexane be considered as a candidate for future listing.
The prioritization of nickel, PFOA and PFOS was opposed by several industry groups.
In comments submitted to DART-IC prior to its November meeting a coalition of 15 trade groups, the Nickel Producers Environmental Research Association (NiPERA) said that current epidemiological data does not support metallic nickel’s prioritization. Consumer exposure via inhalation or oral exposure is “negligible or non-existent,” the coalition added.
3M Company, a manufacturer of perfluorooctanyl based chemicals said that PFOA and PFOS are being voluntarily phased out and therefore do “not warrant the extensive resources necessary for the preparation of hazard identification materials”.
Pentachlorophenol (PCP) and tetrachloroethylene (TCE) – designated “medium/high” priorities by DART-IC – were not included in the OEHHA’s information request.
The hazard identification materials prepared by the agency will be presented to the DART-IC at a future meeting for possible listing under Prop 65.
OEHHA is soliciting submissions for its information request until April 4, 2016. Submissions transmitted by e-mail should be addressed to: P65Public.Comments@oehha.ca.gov (link sends e-mail). Please include the chemical name in the subject line. Comments submitted in paper form may be mailed, faxed, or delivered in person to the addresses below.
