Certain complex biological contaminants, such as lipopolysaccharide (LPS), can interfere with metabolic pathways during toxicity assays. The standard 15-minute Vibrio fischeri bioluminescence assay has limitations when evaluating and screening water toxicity against complex and emerging chemicals like LPS. To accurately determine the effects of such substances, it is crucial to use a bioassay that encompasses a sufficient cell cycle period. This study tested LPS at varying incubation times (ranging from 60 s to 60 min) and concentrations (1-1*10- 12 mg/ml) to identify the appropriate incubation time for bioluminescence inhibition and toxicity testing. The results indicated that bioluminescence inhibition begins within 60 s and reaches maximum inhibition at 60 min. However, at 30 and 45 min, the bacterial response to different concentrations of LPS varied, with some concentrations causing increased bioluminescence. The EC50 values at different times (60 s, 15, 30, 45, and 60 min) were found to be 0.0012, 0.0063, 4.07e + 54, 3.85e-8, and 3.34e-9 mg/ml respectively. This study highlights the importance of considering incubation time when using bioluminescence inhibition to detect acute toxicity in aquatic ecosystems. A longer incubation time may enhance the method's sensitivity and improve its ability to detect low levels of toxins, such as LPS, in water resources.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"113 5","pages":"61"},"PeriodicalIF":2.7,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142520649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

TCS concentrations of 3 mg/L (T1) and 6 mg/L (T2) were applied in a microcosm setup for 28 days to sediment collected from Versova Creek, Mumbai. Among sediment enzymes, dehydrogenase activity exhibited the greatest degree of variability in 3 mg/L exposed sediment.

Total heterotrophic bacteria exhibited an increase in count in T1 and a decrease in T2. Metagenomics data showed a higher relative abundance of bacteria in T1 compared to T2 on the 28th day of sampling. Proteobacteria was found to be the most abundant phylum in all samples, and their relative abundance was reduced by 0.14% in T1 and 5.48% in T2.

At varying concentrations, it was efficient and did not present a significant difference in the removal kinetics. The treatment with the greatest amount of inoculum removed close to 87% of total nitrogen, approximately 70% of orthophosphate, and 77% of chemical oxygen demand. Removals of 84% iron, 44% copper, and 48% manganese were also obtained.

Iron-bound P (≥ 105.56 ± 0.05 mg/kg) was found highest among the P fractions. The bioavailability of P was recorded at peak value during the post-harvest period, contributed by organic P, Iron bound P, and loosely bound P. Principal component analysis inferred that loosely bound P was pH-dependent and significantly influenced by cation exchange, particle density, soil aggregate stability, and total organic carbon (TOC) in the post-harvest soil, whereas TOC, aluminium-bound P, and calcium-bound P in the pre-cultivation soils. Additionally, physico-chemical parameters like electrical conductivity, bulk density, specific gravity, TOC, and soil aggregate stability have a significant impact on the composition of P fractions in the soil. Bioavailable phosphorus (BAP) ranged from 642.78 ± 0.49 to 594.20 ± 1.23 mg/kg during the post-harvest period. Moreover, the contribution of BAP to total P ranged from 99.45 to 99.54%, indicating the fact that soil is sufficient in BAP. Pollution indices revealed that the paddy soils are at risk of eutrophication. Phosphorus Pollution Index (PPI) > 1 exhibited moderate pollution (1.06 to 1.07) at the topsoil (0-15 cm) and PPI < 1, mild pollution (0.92 to 0.99) at 15-30 cm depths.

The results revealed a significant reduction in chlorophyll a content in both algal species upon exposure to PE-MPs, indicating a disruption of photosynthesis. Furthermore, Superoxide Dismutase (SOD) activity decreased in O. princeps, while Catalase (CAT) activity increased in both species, indicating complex physiological responses to microplastic stress. Notably, phycotoxin levels in O. princeps decreased with PE-MP exposure, while those in C. pyrenoidosa increased, particularly with 6.5 μm PE-MPs. These findings underscore the potential toxic effects of PE-MPs on freshwater algal growth and metabolism, as well as their influence on toxin production.
