“…Among the various aquatic ecosystems, ponds are neglected. Several reports have documented the phthalate contamination in zooplankton, wastewater, sediments, river water, wetlands, and estuaries (Li et al, 2017;Wang et al, 2017;Ramzi et al, 2018;Abtahi et al, 2019;Lee et al, 2020;Schmidt et al, 2021;Jönander et al, 2022) but few studies have been reported on phthalate contamination in ponds. Ponds are exceptional freshwater resources that exhibit self-sufficient and self-regulating ecosystems.…”

Phthalates are endocrine disruptors, reported to cause deformities and reproductive damages in animals. Numerous studies reported the presence of phthalates in water samples of rivers, wetlands, and estuaries, while the scenario in case of ponds is different, however they are reported as an integral part of biosphere. In this study, the level of phthalates’ contamination in the water samples collected from the different ponds of Amritsar district for four consecutive seasons in two years was analysed. The maximal level of phthalate contamination was found in samples collected during the monsoon season (July 2015) of first year of sampling followed by post-monsoon (October 2015) and winter season (January 2016). S8 sampling site was found to be the most phthalate contaminated site followed by S1=S11>S2=S9=S4=S5=S7>S6=S3>S10. Benzyl butyl phthalate was most abundant (found in 32% water samples) followed by di-n-butyl and dimethyl phthalate, while diallyl phthalate and diethyl phthalate were not detected. The two main drivers for these seasonal variations were observed to be temperature and precipitation. Hence, this data will be useful to explain the temporal and spatial distributions of phthalates in aquatic ecosystem, as well as to devise cost-effective ways to reduce their ecological footprints.

“…Although most surfactants are degradable, their continuous use and excessive emissions have caused pollution to the water environment ( Bhattacharya et al, 2022 ; Lechuga et al, 2016 ; Mustapha & Bawa-Allah, 2020 ; Rosety-Rodríguez et al, 2002 ). The discharge of cleaning products containing SDS into the water environment through domestic wastewater had toxic effects on aquatic organisms ( Bondi et al, 2015 ; Cruzde Carvalho et al, 2022 ; Jönander, Backhaus & Dahllöf, 2022 ; Messina et al, 2014 ). SDS in the water entered the fish body through gills, skin, or intestinal epithelial cells, circulated to various parts of the body, interrupted the normal steroidogenesis process, and reduced the production of sex hormone ( Moniruzzaman & Saha, 2021 ; Rosety-Rodríguez et al, 2002 ).…”

Sodium dodecyl sulfate (SDS) is an anionic surfactant, which is widely used in various fields in human life. However, SDS discharged into the water environment has a certain impact on aquatic organisms. In this study, planarian Dugesia japonica (D. japonica) was used to identify the toxic effects of SDS. A series of SDS solutions with different concentrations were used to treat planarians for the acute toxicity test , and the results showed that the semi-lethal concentration (LC50) of SDS to D. japonica at 24 h, 48 h, 72 h, and 96 h were 4.29 mg/L, 3.76 mg/L, 3.45 mg/L, and 3.20 mg/L respectively. After the planarians were exposed to 0.5 mg/L and 1.0 mg/L SDS solutions for 1, 3, and 5 days, the activities of superoxide dismutase (SOD), catalase (CAT), and malondialdehyde (MDA) content were measured to detect the oxidative stress and lipid peroxidation in planarians. Random amplified polymorphic DNA (RAPD) analysis was performed to detect the genotoxicity caused by SDS to planarians. The results showed that the activities of SOD, CAT, and MDA content increased after the treatment, indicating that SDS induced oxidative stress in planarians. RAPD analysis showed that the genomic template stability (GTS) values of planarians treated by 0.5 mg/L and 1.0 mg/L SDS for 1, 3, and 5 days were 67.86%, 64.29%, 58.93%, and 64.29%, 60.71%, 48.21%, respectively. GTS values decreased with the increasing of SDS concentration and exposure time, indicating that SDS had genotoxicity to planarians in a time and dose-related manner. Fluorescent quantitative PCR (qPCR) was used to investigate the effects of SDS on gene expression of planarians. After the planarians were exposed to 1.0 mg/L SDS solution for 1, 3, and 5 days, the expression of caspase3 was upregulated, and that of piwiA, piwiB, PCNA, cyclinB, and RAD51 were downregulated. These results suggested that SDS might induce apoptosis, affect cell proliferation, differentiation, and DNA repair ability of planarian cells and cause toxic effects on planarian D. japonica.
