[Progress in the Study of Occurrence, Distribution, Material Flows, and Environmental Release of Substances of Very High Concern （SVHCs） in Plastics].

Plastic additives provide plastics with excellent functions such as plasticizing, flame retardant, and antioxidant properties and are widely used in various plastics. Of these, 189 plastic additives have been included in the European Union's Candidate List of substances of very high concern （SVHCs） due to their potential environmental and health risks. These SVHCs are mainly used in PVC, PUR, and PE plastics and in the packaging, automotive, construction, electronic and electrical equipment, and textile sectors.

Exploring long-term global environmental impacts of chlorinated paraffins (CPs) in waste: Implications for the Stockholm and Basel Conventions and the global plastic treaty.

Chlorinated paraffins (CPs), mainly short-chain CPs (SCCPs) and medium-chain CPs (MCCPs), are currently the most produced and used industrial chemicals related to persistent organic pollutants (POPs) globally. These chemicals are widely detected in the environment and in the human body. As the release of SCCPs and MCCPs from products represents only a small fraction of their stock in products, the potential long-term release of CPs from a large variety of products at the waste stage has become an issue of great concern.

Short and medium-chain chlorinated paraffins in indoor dust from a multistory residential building in Beijing, China: Vertical distribution and potential health risks.

In this study, we conducted a preliminary investigation of the vertical distribution and potential health risks of short and medium-chain chlorinated paraffins (SCCPs and MCCPs) in indoor dust from a multistory residential building in Beijing, China. Forty-eight SCCP and MCCP congener groups in dust from different floors of the multistory residential building were determined by two-dimensional gas chromatography coupled with electron capture negative ionization mass spectrometry. The concentration ranges for SCCPs and MCCPs in the dust samples were 0.

Resolving mass fractions and congener group patterns of C-C chlorinated paraffins in commercial products: Associations with source characterization.

Commercial chlorinated paraffins (CPs) are a source of CPs in the environment, and clarification of the different CP groups present in commercial products is important for source characterization. Resolving CP congener groups is hindered by the complex CP compositions of commercial products. We used comprehensive two-dimensional gas chromatography coupled with electron capture negative ionization high-resolution time-of-flight mass spectrometry to profile 57 C - C CP congener groups in 18 CP-42, CP-52, and CP-70 commercial products.
