“…The condition of the mothers has a significant influence on the frequency of resting egg production, and influences the phenotypic response of their subsequent neonates to adapt to their environmental conditions. [ 33,34 ] Identified morphological deformations, especially deformation of the carapace morphology, production of males and ephippia (or dormant haploid egg), as well as changes in the eggs' color and eggs abortion was observed in Daphnia chronically exposed to lead as an environmental pollutant. It should be noted that the effects observed by [ 34 ] were different to ours with the incidence of bubbling in the abdominal carapace, whereas we observed shortening and losses of tails.…”

Engineered nanoparticles (NPs) undergo physical, chemical, and biological transformation after environmental release, resulting in different properties of the "aged" versus "pristine" forms. While many studies have investigated the ecotoxicological effects of silver (Ag) NPs, the majority focus on "pristine" Ag NPs in simple exposure media, rather than investigating realistic environmental exposure scenarios with transformed NPs. Here, the effects of "pristine" and "aged" Ag NPs are systematically evaluated with different surface coatings on Daphnia magna over four generations, comparing continuous exposure versus parental only exposure to assess recovery potential for three generations. Biological endpoints including survival, growth and reproduction and genetic effects associated with Ag NP exposure are investigated. Parental exposure to "pristine" Ag NPs has an inhibitory effect on reproduction, inducing expression of antioxidant stress related genes and reducing survival. Pristine Ag NPs also induce morphological changes including tail losses and lipid accumulation associated with aging phenotypes in the heart, abdomen, and abdominal claw. These effects are epigenetic remaining two generations post-maternal exposure (F2 and F3). Exposure to identical Ag NPs (same concentrations) aged for 6 months in environmentally realistic water containing natural organic matter shows considerably reduced toxicological effects in continuously exposed generations and to the recovery generations.

“…Exposure to petroleum hydrocarbons causes several toxicological responses to exposed organisms, including carcinogenicity, genotoxicity and mutagenicity, among others (Logeshwaran et al 2018;Braun et al 2019;Ossai et al 2020;Akinola et al 2020;Kuppusamy et al 2020). In addition to petroleum hydrocarbon contamination, the presence of metals and trace elements, even at low concentrations in the environment, can cause toxic effects to human and environmental health, as reported by several previous studies (Wu et al 2016;Araujo et al 2019;Vardhan et al 2019).…”

“…Tested concentrations of Pb at 0.05 mg L -1 have demonstrated its bioaccumulation potential and associated chronic effects on several generations D. similis (i.e., carapace malformations, production of males, ephippia, aggregation in neonates' dorsal region, reddish extremities, aborted eggs and changes in the eggs' colour) (Araujo et al 2019). Moreover, the toxicity results found in groundwater wells without detectable concentrations of gasoline or Pb could be related to natural differences in water hardness, since the pH of the samples were within the recommend standard range 5-9 (ABNT 2016).…”

To assess the ecological risk resulting from an accidental gasoline spill upstream from a wetland, groundwater and sediment sampling was carried out during two campaigns at the 48th and 52nd months after the spill had occurred. In total, 21 groundwater monitoring wells in the affected area were sampled plus an additional reference well located upstream from the accident location. Seven sediment sampling points were selected inside the wetland, plus a reference point upstream from the accident. Physicochemical parameters, BTEX (benzene, toluene, ethylbenzene, m-xylene, p-xylene and o-xylene) and metal concentrations were analysed to estimate the chemical risk. Acute (Allivibrio fischeri, Daphnia similis, Hyalella azteca) and chronic (Artemia salina and Desmodesmus subspicatus) toxicity assays were performed with groundwater and sediments elutriate to determine the ecotoxicological risk. Results from groundwater indicated an extreme chemical level of risk in14 out of 21 monitoring wells. These 14 wells also exhibited free-phase gasoline and lead (Pb) concentrations above the threshold values adopted by this study. The presence of Pb, however, could not be associated with the gasoline accident. High acute and chronic toxicities were reported for the majority of wells. Conversely, the risks associated with the sediments were considered low in most sampling points, and the ecotoxicity found could not be related to the presence of gasoline. Groundwater flow modelling results have evidenced the migration of the contamination plume towards the wetland. Thus, to prevent contamination from reaching the protected area, more effective groundwater clean-up techniques are still required.

In this study, the life trait responses of a model toxicity zooplankton, Daphnia magna, to single di‐2‐ethylhexyl phthalate (DEHP) and its mixture with Pb and Cd at environmentally relevant concentrations (50 µg L–1 for DEHP, 4.2 µg L–1 for Pb, and 5.4 µg L–1 for Cd) were investigated. The DEHP did not impact the survival rate, maturation and reproduction of D. magna. However, in the binary exposures of D. magna to DEHP and the metals, the organisms severely suffered from high mortality proportion, from 70% to 100%. The mixtures of DEHP, Pb, and DEHP with the two metals caused the significant maturation postponement of the D. magna. Besides, mother D. magna exposed to the mixtures of DEHP and metals produced much lower relatives of the accumulative offspring number, from 3.7% to 77.7%, compared to the control. Energy cost would be the root of the impairment. The combined effects of DEHP and metals in the present study help provide more environmentally realistic toxicity of the pollutants than a single one to the freshwater cladoceran D. magna which have been understudied. The results suggest that DEHP should be included in the Vietnam safety guidelines (QCVN) for water monitoring.
