Dr. Anders Abelmann will be presenting on research related to formaldehyde emissions from laminate flooring during a roundtable session at the American Home Furnishings Alliance's (AHFA) Regulatory Summit in Hickory, NC, on September 15th. His presentation will be based on the findings recently published in Regulatory Toxicology and Pharmacology, titled  An Assessment of Formaldehyde Emissions From Laminate Flooring Manufactured in China.  For more information, please visit either the AHFA website, or contact Dr. Anders Abelmann.

Scientists at Cardno ChemRisk recently published a study titled “Anthophyllite asbestos: state of the science review” in the Journal of Applied Toxicology. The purpose of this research was to provide a comprehensive review of the toxicological, epidemiological and regulatory knowledge regarding anthophyllite and to understand how it compares to other types of asbestos. It also serves to give an overview of the available published literature on anthophyllite, including the occurrence of anthophyllite in talc and related health effects.

The authors reviewed publicly available documents on anthophyllite discussing its use, mining, properties, toxicity, exposure, and any potential health hazards. Based on their research, the authors found that:

·         Anthophyllite has been less researched than other asbestos types.

·         Anthophyllite can be found as a trace element or contaminant of other asbestos or talc deposits.

·         In studies from the 1970s and onward, it was reported that significant anthophyllite exposure in animal studies can cause asbestosis, lung cancer, and mesothelioma.

·         A study of Finnish Anthophyllite miners in the 1970s found exposure to anthophyllite caused asbestosis and lung cancer, but not mesothelioma, which was not linked with human exposure to anthophyllite until the mid-1990s.

·         Because of the lack of research on anthophyllite specifically, characterizing the health risks associated with exposure is difficult.

Overall, the authors concluded that anthophyllite may be more potent than other types of asbestos in causing asbestosis, but less potent in causing mesothelioma. However, further research is needed to fully understand the toxicity of pure anthophyllite.

The abstract of the article is available here. If you would like a full copy of the paper, or if you have any questions regarding its content, please contact Dr. Shannon Gaffney.

TSCA Stakeholder Meeting for Risk Assessment and Risk Prioritization- Will Your Business be Ready?

The U.S. Environmental Protection Agency (EPA) held two public meetings to gather input that will inform a proposed rule to establish a risk-based process for chemical prioritization (August 10), in addition to its process for conducting risk evaluations to determine whether a chemical presents an unreasonable risk of injury to health or the environment under TSCA section 6(b) (August 9).

By June 2017, EPA must decide on a risk-based screening process for evaluating new and existing chemicals. The previous “unreasonable risk” standard will be replaced by the “safety standard” for regulating chemicals, which will consider both hazard and exposure in a risk-based approach that is protective of human health and the environment.

During these meetings, stakeholders from government, private industry, academia, non-governmental organizations, as well as medical professionals, offered feedback regarding their suggestions and concerns. Cardno ChemRisk scientists, Dr. Denise Hill and Ms. Claire McMenamy, attended the meetings, and offer the following observations, as well as the selected comments, repeatedly offered by multiple stakeholders:

California's Office of Environmental Health Hazard Assessment (OEHHA) adopted a temporary emergency regulation on April 18, 2016, which implemented warning label method and content provisions specifically for exposures to BPA from canned and bottled foods and beverages sold at retail level. Effective May 11, 2016, BPA exposure warnings must be affixed to the product container or, alternatively, posted on a sign at each point-of-sale (cash register, check-out line) in the retail location; in addition, the emergency regulation stipulates strict warning language requirements that specify the chemical of interest and its health endpoint of concern ("harm to the female reproductive system"). The provisions in the emergency regulation are in effect until October 17, 2016.

On July 29, 2016, OEHHA issued a notice of proposed rulemaking to continue the emergency BPA warning regulation provisions until December 30, 2017. However, this new regulation limits the scope of the point-of-sale warning provisions. To utilize point-of-sale warning signs rather than individual product labels, food and beverage companies that intentionally use BPA must submit the following product identifying information in a "searchable, electronic format" to OEHHA:

• Brand name

• Product description, including FDA product category

• Universal Product Code or other identifying designation

• Where applicable, the last expiration or 'use by' date for the product(s) where BPA was intentionally used

Once submitted, OEHHA will publish the above information on its website, so that consumers can learn where BPA is intentionally used in food and beverage containers. A public hearing on the proposed regulatory amendment is scheduled for 10:00 a.m. on September 12, 2016 in the Sierra Hearing Room at the CalEPA Headquarters building 1001 I Street in Sacramento. The hearing will also be webcast.
