EPA Begins Process to Prioritize Five Chemicals for Risk Evaluation Under Toxic Substances Control Act

 Environmental Protection Agency (EPA) announced that it is beginning the process to prioritize five additional toxic chemicals for risk evaluation under the nation’s premier chemical safety law. If, during the 12-month long statutory process, EPA designates these five chemicals as High Priority Substances, EPA will then begin risk evaluations for these chemicals.


EPA plans to prioritize the following chemicals for risk evaluation under the Toxic Substances Control Act (TSCA):

Acetaldehyde (CASRN 75-07-0),

Acrylonitrile (CASRN 107-13-1),

Benzenamine (CASRN 62-53-3),

4,4’-Methylene bis(2-chloroaniline) (MBOCA) (CASRN 101-14-4), and

Vinyl Chloride (CASRN 75-01-4).


“Under the Biden-Harris Administration, EPA has made significant progress implementing the 2016 amendments to strengthen our nation’s chemical safety laws after years of mismanagement and delay. Today marks an important step forward,” said Assistant Administrator for the Office of Chemical Safety and Pollution Prevention Michal Freedhoff. “Moving forward to comprehensively study the safety these five chemicals that have been in use for decades is key to better protecting people from toxic exposure.”


“Most vinyl chloride is used to make polyvinyl chloride (PVC) plastic, which poses significant health and environmental problems that have been known for over 50 years. This is one of the most important chemical review processes ever undertaken by the EPA. I applaud the EPA for launching this review,” said Judith Enck, President of Beyond Plastics and former EPA Regional Administrator.

This step is consistent with a commitment from the Biden-Harris Administration to understand and address environmental and toxic exposures as part of the Cancer Moonshot’s mission to end cancer as we know it, and as progress on delivering environmental justice.


Going forward, EPA expects to initiate prioritization on five chemicals every year, which will create a sustainable and effective pace for risk evaluations. Prioritization is the first step under EPA’s authority to regulate existing chemicals currently on the market and in use – to evaluate whether health and environmental protections are needed.

Today's KNOWLEDGE Share : Researchers Create Deployable Silk Fibers for Adhering and Lifting Objects

Today's KNOWLEDGE Share The stream of liquid silk quickly turns to a strong fiber that sticks to and lifts objects These sticky fibers, created at the Tufts University Silklab, come from silk moth cocoons, which are boiled in solution and broken down into their building block proteins called fibroin.The silk fibroin solution can be extruded through narrow bore needles to form a stream that, with the right additives, solidifies into a fiber when exposed to air.  Nature is the original inspiration for deploying fibers of silk into tethers, webs, and cocoons. Spiders, ants, wasps, bees, butterflies, moths, beetles, and even flies can produce silk at some point in their lifecycle.Nature also inspired the Silklab to pioneer the use of silk fibroin to make powerful glues that can work underwater, printable sensors that can be applied to virtually any surface, edible coatings that can extend the shelf life of produce,a light collecting material...

Today's KNOWLEDGE Share : biobased content of polycarbonate diols

Today's KNOWLEDGE Share MCG increases biomass content of polycarbonate diols Mitsubishi Chemical Group (MCG) has introduced grades of its Benebiol biomass-based polycarbonate diols that have a higher biomass content. The product is primarily used in the manufacture of polyurethane resins for coatings in sectors such as automotive, furniture and outdoor products. It is also used in the production of artificial leather. Existing Benebiol grades had a bio-based content of 20-50%, but the new HSS and NLDS grades have a biomass content in excess of 80%. Some of its previous petroleum-derived grades have also been converted to biomass, as the NLS grades. This, the company said, allows it to offer bio-based grades of all its Benebiol products. The shift to biomass-based raw materials while maintaining high-quality functions will contribute to our customers’ efforts to achieve sustainable manufacturing. source:MCG/www.utech-polyurethane.com
