SCIENCE ADVISORY BOARD

TURI supports the work of the TURA Science Advisory Board (SAB) which consists of eleven members appointed by the Governor.  Nominations are as follows: Executive Office of Environmental Affairs (3), TURI (3), Economic Development (3), Labor and Workforce Development (1) and Executive Office of Health and Human Services (1). Scroll down to meet our current members.

The primary role of the SAB is to consider petitions to add or delete chemicals from the TURA chemical list and make recommendations accordingly.  TURI supports the work of the SAB as described in Chapter 211, Section 6, line 496 of the TURA statute and otherwise requested by the legislature. The governing body of TURA may call on the SAB for scientific or technical advice concerning other TURA-related issues, including the designation of substances as higher hazard or lower hazard.

Recent Topics

Aryl Phosphate Esters

Aryl Phosphate Ester Category Consideration – At their December 2024 meeting, the SAB began discussing adding the ‘aryl phosphate esters’ category to the TURA chemical list.  That discussion is on-going and TURI welcomes scientific information contributed by stakeholders.  Please send information to Heather Tenney.

While researching flame retardants for the MA Flame Retardants (FR) Law of 2020, a group of nonhalogenated phosphate esters, specifically aryl organophosphate esters and derivatives, came into focus as an important potential chemical category for listing under TURA due to human and environmental hazard characteristics. None of these chemicals are currently covered by the MA FR Law or MA TURA. In addition to their use as flame retardants, chemicals in this category are also used as plasticizers and lubricants in hydraulic fluids, rubber, paints, textile coatings, food packaging, and PVC. The more widely studied members of this category are triphenyl phosphate, isopropyl triphenyl phosphate and tricresyl phosphate.

TransDCE (trans-1,2-dichloroethylene)

During their October 2024 meeting, the SAB discussed the potential designation of trans-1,2-dichloroethylene (TransDCE) as a “higher hazard” substance. TransDCE is already included on the TURA list with standard reporting thresholds of 25,000 lbs. manufactured or processed and 10,000 lbs. used otherwise. If it were to be classified as a higher hazard substance, the threshold would be lowered to 1,000 lbs. Due to the fact that transDCE serves as the easiest and fastest drop-in replacement for TCE currently, TURI has provided guidance outlining the hazards associated with transDCE, along with its similarities to trichloroethylene (TCE) and its frequent pairing with HFEs, which fulfill the TURA definition of PFAS. The SAB concluded the meeting with a ‘wait and see’ approach, anticipating more data in the near future.

Flame Retardants

Between March 2023 and June 2024, the TURA Science Advisory Board held eight meetings to discuss flame retardant chemicals and provide guidance to MassDEP as mandated by the 2020 Law: AN ACT TO PROTECT CHILDREN, FAMILIES, AND FIREFIGHTERS FROM HARMFUL FLAME RETARDANTS. A summary of this work is provided here, and the collection of advice and summary statements given to MassDEP is available here.

Quaternary Ammonium Compounds (Quats or QACs)

From September 2020 to June 2021, the SAB discussed the listing of Quaternary ammonium compounds (“QACs” or “quats”). QACs represent a broad class of several hundred chemicals. They were first discovered in the early 1940s and are primarily used as active ingredients in antimicrobials, disinfectants, sanitizers, and surfactants. In addition to disinfection, QACs have many other applications, including wood preservatives, herbicides, eye drops, mouthwashes, nasal sprays, detergents, shampoos, dryer sheets, and fabric softeners.

In reviewing the science about two groups of QACs with the following representative chemicals, didecyl dimethyl ammonium chloride (DDAC) and alkyl dimethyl benzyl ammonium chloride (ADBAC), the SAB had concerns related to these substances. These included respiratory system irritation and inflammation, including outcomes consistent with occupational asthma and work-exacerbated asthma; corrosive effects; hazard for aquatic life; and environmental fate and persistence. The SAB also had additional concerns about reproductive effects and neural tube development.

After reviewing the science and hazards associated with QACs, the TURA Science Advisory Board recommended in May 2021 that certain DDAC and ADBAC chemicals be included on the TURA list of Toxic or Hazardous Substances. The TURA Administrative Council subsequently voted to include these specific DDAC and ADBAC chemicals on the list.

Carbon Nanotubes and Nanofibers

From June 2021 to September 2023 the SAB discussed a petition to list carbon nanotubes (both single-walled and multi-walled) and carbon nanofibers to the TURA chemical list.  Carbon nanotubes (CNTs) are tiny tubes formed from one or several hexagonal graphene sheets consisting of carbon atoms. Carbon nanotubes can be single-walled or double-walled and can vary significantly in physical characteristics. Single-walled carbon nanotubes (SWCNTs) often have diameters ranging anywhere from 1 to 3 nm, multi-walled carbon nanotubes (MWCNTs) range from 10-100 nm, and carbon nanofibers (CNFs) range from 40 to 200 nm. Their lengths can vary more widely, ranging from tens of micrometers to several centimeters.1 The defining feature distinguishing CNF from CNT resides in graphene plane alignment. If the graphene plane and fiber axis do not align, the structure is characterized as CNF, but when parallel, the structure is considered a CNT.2

The SAB recommended that multi-walled carbon nanotubes (MWCNTs), single-walled carbon nanotubes (SWCNTs), and carbon nanofibers (CNFs) be added as three distinct categories to the TURA list of Toxic or Hazardous Substances.

The SAB recommended that multi-walled carbon nanotubes (MWCNTs), single-walled carbon nanotubes (SWCNTs) and carbon nanofiber (CNFs) be added as three separate categories to the TURA list of Toxic or Hazardous Substances.

PFAS (per- and polyfluoroalkyl substances)

From 2016 to 2020, the SAB reviewed PFAS. These substances are often referred to as “forever chemicals” because they do not fully break down in the environment and have been detected in drinking water around the world. PFAS encompass a category of thousands of chemicals that are widely used in manufacturing and consumer products, leading to broad exposure. They are linked to various adverse health outcomes, including cancer and negative effects on the endocrine and metabolic systems, particularly concerning the liver and thyroid.

Ryan M. Bouldin holds a Ph.D. in Chemical Engineering with an emphasis in Green Chemistry. He believes strongly that his work reflects more than just mixing chemicals to make new materials. While the goal of creating new materials is to incorporate them into new products, he believes those products should be nourishing to the communities that both create and use them. They must be safe and effective for both workers and consumers. This creates demand up supply chains for materials and processes that are ethical, economically viable, and beneficial for people and the planet. This belief is the philosophy of his work at Bentley.
