Determination of chlorinated paraffins (CPs): Analytical conundrums and the pressing need for reliable and relevant standards

Alwyn R. Fernandes et al.

Summary: The determination of chlorinated paraffins (CPs) has been a challenging issue in analytical chemistry due to the complex mixture of congeners and steric interactions. However, recent advances in instrumentation and interlaboratory studies have provided a better understanding of these challenges, including variability in results, instrumentation limitations, and the need for a more extensive set of standards to improve accuracy in CP determination.

Revisiting pesticide pollution: The case of fluorinated pesticides

Diogo A. M. Alexzandrino et al.

Summary: Fluorinated pesticides have gained significant market share in the agrochemical sector due to the approval of new fluoroorganic ingredients in the past two decades. However, there is lack of a comprehensive scientific and regulatory framework to address their potential negative impacts. Further research and discussion are needed to differentiate between the safety and hazards associated with fluorinated pesticides.

Identifying emerging environmental concerns from long-chain chlorinated paraffins towards German ecosystems

Bo Yuan et al.

Summary: The study revealed the presence of various types of chlorinated paraffins in different ecosystems across Germany, with long-chain products showing higher concentrations. Data from bream samples collected downstream of a CP-manufacturing factory indicated a significant increase in concentrations of LCCPs over time, reflecting the impact of chemical regulation policies on CP production. The findings serve as an early warning of environmental concerns related to the increasing global production and use of LCCPs.

Biomagnification and Temporal Trends of New and Emerging Dechloranes and Related Transformation Products in Baltic Sea Biota

Peter Haglund et al.

Summary: In this study, suspect screening was performed to evaluate the presence of dechloranes and their transformation products in Baltic Sea biota. A total of 31 compounds were identified, including dechloranes and their transformation products. Some transformation products had higher concentrations than the parent compounds, with Dechlorane 603 TPs being more than 10 times more abundant. The concentrations of contaminants in the most contaminated species showed little change over a period of 52 years. Most compounds exhibited a slow declining trend in concentrations, while DP and DP-TPs showed an increasing trend. The transformation products showed biomagnification, with similar or higher trophic magnification factors compared to the parent compounds.

Per- and polyfluoroalkyl substances (PFAS) in sludge from wastewater treatment plants in Sweden - First findings of novel fluorinated copolymers in Europe including temporal analysis

Felicia Fredriksson et al.

Summary: This study analyzed 81 PFAS in sludge samples collected from wastewater treatment plants in Sweden to understand their usage in society. The results showed detectable levels of C8 and C4-FASA-based copolymers in all sludge samples. There was an overall declining trend in the concentration of PFAS, and a shift from C8-based chemistry toward shorter chain lengths was observed.

Comparison of extraction methods for per- and polyfluoroalkyl substances (PFAS) in human serum and placenta samples-insights into extractable organic fluorine (EOF)

Andreas-Marius Kaiser et al.

Summary: Since the detection of PFAS in humans and the environment, attention and concerns have increased. The fluorine mass balance approach revealed unidentified organofluorine in environmental samples, with LC-MS/MS showing potential for analysis of PFAS. Different extraction methods resulted in varying recovery rates and EOF concentrations, highlighting the importance of method choice for target PFAS and EOF analysis.

Human Exposure to Chlorinated Paraffins via Inhalation and Dust Ingestion in a Norwegian Cohort

Bo Yuan et al.

Summary: Different chain lengths of chlorinated paraffins were found in indoor air and dust collected from living rooms of adults in a Norwegian cohort. Relatively volatile chlorinated paraffins showed a greater tendency to transfer from settled dust to indoor air, with inhalation being the predominant exposure pathway.

Kota Mukai et al.

Summary: This study utilized gel permeation chromatography to fractionate extracts from liver samples of high-trophic marine and terrestrial mammals, revealing significant differences among species in both concentrations and contributions of chlorine and bromine compounds. The results suggest the need for further analysis of unidentified chlorinated compounds in terrestrial mammals and unidentified brominated compounds in marine mammals.

Combustion ion chromatography for extractable organofluorine analysis

Rudolf Aro et al.

Summary: Combustion ion chromatography is utilized in environmental analytical chemistry to assess PFASs and other organofluorine burden. Experimental results showed that CIC combustion efficiencies ranged from 66-110%, and calibrating CIC with different fluorine sources can lead to discrepancies in results.
