Summary: Although multielement isotope fractionation studies have been well-established for point-source pollution, they are only emerging for diffuse pollution by micropollutants like pesticides. This study found that chlorine isotope fractionation can be a robust indicator of chloroacetanilide degradation, with distinct patterns observed for different degradation pathways. The 3D isotope approach allows for differentiation of transformations that may not be distinguishable based on C and N isotope data alone.

Summary: This study comprehensively investigated the anaerobic microbial degradation of a novel brominate flame retardant, 1,2-bis(2,4,6-tribromophenoxy)ethane (BTBPE), in wetland soils. The results showed that BTBPE degradation mainly occurred through stepwise reductive debromination, while maintaining the stability of the 2,4,6-tribromophenoxy group. Additionally, significant carbon isotope fractionation was observed during BTBPE microbial degradation, indicating cleavage of the C-Br bond as the rate-limiting step. This study demonstrated that anaerobic microbes in wetland soils can degrade BTBPE, and compound-specific stable isotope analysis is a robust method for discovering underlying reaction mechanisms.

Summary: This study investigates the carbon and nitrogen isotope fractionation characteristics during the degradation of atrazine in a constructed wetland. The observed isotope parameters are consistent with those observed in the cultivation of specific strains, indicating similarities in the biodegradation pathway and mechanism. However, variations in carbon and nitrogen isotope fractionation across different phases may lead to over- or underestimation of atrazine biodegradation extent. The accuracy of estimation improves when using the enrichment factor derived from batch cultivation of pore water. This study advances the application of compound-specific stable isotope analysis in tracking atrazine biodegradation in ecosystems, emphasizing the importance of carefully selecting and applying the enrichment factor for quantifying intrinsic biodegradation.

Summary: In this study, multi-element compound-specific stable isotope analysis was used to evaluate the α-HCH and γ-HCH transformations catalyzed by LinA1 and LinA2 enzymes. The results showed slight differences in the isotopic fractionation patterns of different enantiomers, but both enzymes exhibited similar reaction mechanisms during γ-HCH transformation.

Summary: The microbial degradation of n-hexadecane (n-C16) and n-heneicosane (n-C21) in soil during natural attenuation (NA) and bioaugmentation (BA) was investigated using compound-specific stable isotope analysis (CSIA), microbial community analysis, and key enzyme gene analysis. Both NA and BA treatments resulted in over 95% degradation of n-C16 and n-C21 within 3 and 6 days, respectively, with slightly faster degradation in BA. CSIA showed that n-C16 exhibited a reverse hydrogen isotope fractionation effect, while n-C21 showed a normal hydrogen isotope fractionation effect, and the degree of fractionation was higher in BA than in NA. The dominant microbial genera involved in degradation differed between BA and NA, and certain added strains during BA, such as Rhodococcus and Brevundimonas, showed high potential for alkane contamination remediation. The alkB and almA genes played key roles in the biodegradation of n-C16 and n-C21, with alkB being more promoted by n-C16 and almA being more motivated by n-C21. The different types of alkane-degrading bacteria with different enzyme reaction kinetics may explain the opposite hydrogen isotope fractionation observed during the biodegradation of n-C16 and n-C21. Overall, CSIA is a suitable technique for quantitatively evaluating the biodegradation of different alkanes during NA and BA bioremediation processes in contaminated sites.

Summary: This study used compound-specific isotope analysis to investigate the variation of delta N-15 associated with microbial processes in marine sediment samples. The results showed that the decrease in amino acid concentrations in sediment was accompanied by an increase in delta N-15 values. Phenylalanine displayed a depth-dependent variation in microbial utilization, while glycine showed the highest relative molar contribution and delta N-15 increase in deep sediment. These findings provide an important basis for interpreting the delta N-15 values of amino acids in sediment.

Summary: Compound-Specific Isotope Analysis (CSIA) is a useful tool for studying the biodegradation of metalaxyl in soil and plants. Microbial degradation was found to have the most significant impact on the degradation of metalaxyl in soil. CSIA was used to investigate the biodegradation and isotope fractionation of metalaxyl in water spinach, showing that both absorption and degradation processes can cause shifts in delta C-13 values. Additionally, the relationship between carbon isotope ratios and residual concentration of metalaxyl was described by the Rayleigh equation, allowing for the calculation of the biodegradation rate of metalaxyl using CSIA.

BB-80 causes pathological changes in the thyroid, while OH-BB-80 increases thyroid hormone content. After discontinued exposure, both BB-80 and OH-BB-80 downregulate thyroid-related genes, but the whole-body thyroid hormone levels fail to fully recover.

Summary: Pesticides can have long-term effects on aquatic ecosystems through transgenerational toxicity, particularly for chiral pesticides. This study evaluated the maternal transfer risk of the chiral triazole fungicide tebuconazole (TEB) in zebrafish models and found that exposure to the R-enantiomer of TEB had greater impacts on offspring malformation and swimming speed compared to the S-enantiomer. Enantioselective effects on thyroid hormones and related genes were also observed, highlighting the importance of enantioselectivity in the ecological risk assessment of chiral pesticides through maternal transfer.

The concentrations did not vary significantly over the past decade for PBDEs, but lower-brominated congeners increased with time. The concentrations of NBFRs also increased over time, with higher concentrations in 2021, 2016, and 2013 compared to 2011. The health risks of PBDEs and NBFRs were found to be low, but long-term health risks of BFRs should be considered.

Summary: The nitration levels of important house dust mite (HDM) allergens Der f 1 and Der p 1 in indoor dust samples were investigated using liquid chromatography coupled to tandem mass spectrometry. All ten tyrosine residues in Der f 1 and Der p 1 were found to be nitrated to different degrees in indoor dusts. Y56 in Der f 1 and Y37 in Der p 1 were the preferred nitration sites with nitration degrees ranging from 7.6% to 84% and from 17% to 96%, respectively. Further research is needed to determine if nitration aggravates the health effects of HDM allergens and if it is site-dependent on tyrosine residues.
