“…OCPs enter water bodies through dry and wet deposition from the air, accumulating in rivers, lakes, and global oceans [13], causing negative impacts on aquatic organisms. The LC 50 value recorded on D. magna after 48 h exposure to DDT in this study was 4.8 µg/L, which was higher than the value in the study by Kuo et al, (2012) 1.4 µg/L [14] but lower than the value recorded in the study by Mejía-Saavedra et al, (2005) 5.2 µg/L [15], by Ivorra et al, (2019) 260 µg/L [16]. After 48 h of exposure to DDT, the LC 50 value in this study with M. macrocopa was 1.7 µg/L, much lower than the result recorded by Liu et al, (2008) 324 µg/L [6].…”

DDT (Dichloro-diphenyl-trichloroethane) and chlordane are the organochlorine pesticides (OCPs) in which dangerous to human health and easily accumulate in biological tissues, using to control insects in crops, livestock and house protection. The aim of this study was to evaluate the toxicity of DDT, Cis (alpha - chlordane) and Trans (gamma - chlordane) on the growth of two crustaceans species Daphnia magna (D. magna) and Moina macrocopa (M. macrocopa) after 24 h and 48 h. Each test concentration selected 9 individuals of each species and repeated 4 experimental times, the study results showed that the 50% lethal concentration (LC50) of D. magna and M. macrocopa when exposed to DDT for 24 h were 20.8 μg.L-1 and 13.5 μg.L-1, respectively; after 48 h the value decreased to only 4.8 μg.L-1 and 1.7 μg.L-1. Similarly, LC50 values of Cis (alpha - chlordane) on 2 species after 24 h of exposure were 12.4 μg.L-1 and 11.8 μg.L-1, respectively; after 48h are 4.6 μg.L-1 and 4.9 μg.L-1. The calculation results of LC50 when exposed to Trans (gamma - chlordane) of D. magna and M. macrocopa after 24 h are 17.6 μg.L-1 and 12.4 μg.L-1, respectively; after 48 hours, it decreased to 3.8 μg.L-1 and 3.7 μg.L-1 (p < 0.05). The results of the acute toxicity assessment also indicated that M. macrocopa was more sensitive to toxicity than D. magna with the same test conditions.

“…This feeding strategy is common in zooplankton organisms. This and other features make A. salina an excellent model organism for the study of MPs pollution influence on zooplanktonic trophic webs, as already suggested by other authors [79,80]. Moreover, these organisms are involved in biomagnification phenomena [29,48].…”

In the present study, it has been evaluated how 10 µm of polyethylene microspheres can be ingested by Artemia salina (Linnaeus, 1758) larvae within the first 7 days of the life cycle, and the impact on their health. Twelve A. salina larvae (instar I) groups were exposed to different microplastics (MPs) concentrations (0-1-10-102-103-104 MPs/mL), with and without Dunaliella salina as a food source. The results highlighted that A. salina larvae ingest MPs in relation to the exposure times in a dose-dependent manner and are significantly influenced by food availability. The highest contamination found was 306.2 MPs/individual at 104 MPs/mL exposure without a food source. No MPs were found in the presence of the food source from 1 to 102 MPs/mL, while contamination was detected at all concentrations of MPs without a food source. The worst effect on the developmental stages was evaluated at 168 h with a food source, with a delay compared to the control of I and II instars at 103 and 104 MPs/mL, respectively. Furthermore, microalgal feeding was significantly reduced for about 50% in the presence of 104 MPs/mL. These results highlight that aquatic microplastics pollution could affect the A. salina’s feeding behavior and life cycle.

“…sis at 20°C and pH 7)-4,4′-dichlorobenzophenone (DCBP) is the main metabolite and probably the most available form in surface waters (Fujii et al, 2011;Thiel et al, 2011;Yin et al, 2017;FOOT-PRINT PPDB). In fact, 4,4′-DCBP, was quantified in surface waters (2.79-29.87 ng/L) from the mouth of the Pearl River Delta in a previous study (Ivorra et al, 2019). Some metabolites are often more persistent than their corresponding parent compounds and exhibit similar or even greater toxicity, e.g.…”

“…The compound was extracted by solid-phase extraction (SPE) using the OASIS HLB cartridges (200 mg, 6 cc; Waters, Ireland) following Ivorra et al (2019) protocol. Briefly, fortified water samples were loaded into pre-conditioned cartridges (5 mL CH 3 OH followed by 5 mL ultrapure water), allowed to dry, and eluted (2.5 mL C 4 H 8 O 2 followed by 2.5 mL of CH 2 Cl 2 and 2.5 mL more of a 1:1 mix of CH 2 Cl 2 and C 4 H 8 O 2 (v/v)).…”

Uptake and depuration kinetics of 4,4′-dichlorobenzophenone (main metabolite of dicofol) in the edible clam Meretrix meretrix were evaluated through a mesocosm experiment. M. meretrix was exposed to different dicofol concentrations (environmental concentration, D1 = 50 ng/L; supra-environmental concentration, D2 = 500 ng/L) for 15 days, followed by the same depuration period. To accomplish this goal, an analytical method was successfully optimized for 4,4′-DCBP using QuEChERS as extraction method with a range of concentrations 0.3-76.8 ng/g ww quantified by gas chromatography coupled to tandem mass spectrometry. Our results demonstrated different kinetics of accumulation depending on the two dicofol treatments. For D1, the uptake kinetic was best fitted using a plateau followed by one phase association kinetic model, while for D2 a one phase association kinetic model suited better.Similar bioconcentration factors were obtained for both concentrations but only animals exposed to D2, showed 4,4′-DCBP levels above the limits of quantification after 24 h exposure. These animals also showed lower uptake rate (k u ) than organisms exposed to D1.During the depuration period, only organisms exposed to D1 successfully depurated after 24 h. On the other hand, although animals exposed to D2 presented higher elimination factor, they did not reach the original levels after depuration. Moreover, values detected in these clams were higher than the Maximum Residue Level (10 ng/g) established by the European legislation. This indicates that longer periods of depuration time than the ones used in this study, may be needed in order to reach safe levels for human consumption. This work also demonstrated that studies on metabolite kinetics during uptake/depuration experiments, could be a new alternative to understand the impact and metabolism of pesticides in the marine environment.
