TOXICS USE REDUCTION ACT (TURA)
Categorization of the Toxics Use ReductionList of Toxic and Hazardous Substances
Toxics Use Reduction Science Advisory Board has performed this project to categorize the 258 chemicals which have ever been reported under the Massachusetts Toxics Use Reduction Act (TURA). The resulting lists of more hazardous’, less hazardous and uncategorized chemicals will be used by the Toxics Use Reduction Program to aid in setting priorities and will serve as guidance for companies making chemical substitution decisions. The lists of more hazardous (Category 1) and less hazardous (Category 2) substances follow. The specific chemicals in the categories may change based on new data becoming available or new chemicals being used above TUR reportable threshold quantities in the Commonwealth.
Quaternary Ammonium Compounds (QACs)
The TURA Science Advisory Board (SAB) has recommended that certain Didecyl Dimethyl Ammonium Chloride (DDAC) and Alkyl Dimethyl Benzyl Ammonium Chloride (ADBAC) chemicals be added to the TURA list of Toxic or Hazardous Substances. In reviewing the science about DDAC and ADBAC, the SAB had concerns related to these substances, including 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 had additional concerns for reproductive effects and neural tube development. This policy analysis summarizes key scientific information on DDAC and ADBAC; estimates the number of facilities that are likely to enter the program as a result of the proposed listing; analyzes opportunities and challenges new filers are likely to face; and discusses the implications of this policy measure for the TURA program. Based on this analysis, the Toxics Use Reduction Institute supports the SAB’s recommendation that DDAC and ADBAC be added to the TURA list of Toxic or Hazardous Substances.

Environmental Justice through Toxics Use Reduction
Toxics Use Reduction is a best practice for advancing the pursuit of environmental justice for all. Our 2025 Environmental Justice report draws upon TURA Data, aiming to help government agencies, businesses, and communities identify opportunities to advance environmental justice by reducing the use of Toxics in Massachusetts.

Competitiveness Impacts for Massachusetts Businesses
Summarizes the successes of 12 companies, documenting costs and savings as a direct result of toxics use reduction or resource conservation efforts. In addition to financial benefits, some companies improved employee health and morale and increased recognition for their products and services.
EMS Planning Guidance
The Toxics Use Reduction Act (TURA, MGL c.21I) and its regulations at 310 CMR 50.00 establish toxics use reduction as a central component in the Commonwealth’s efforts to protect public health and the environment and to promote the competitive advantage of Massachusetts businesses through efficient materials use and management.
