“…Eleven heavy metals were monitored in the pre-to-post lockdown including the four critically categorized four heavy metals such as arsenic (As), cadmium (Cd), chromium (Cr), and lead (Pb) (Kaur et al 2011 ; Han et al 2019 ; Rahman and Singh 2019 ). The lead concentration decreased significantly in the recent assessments when compared with pre-lockdown.…”

Environmental impact of COVID-19 imposed lockdown (2020) and the new normal condition (2021) on two different beaches of India (Ghoghla beach, Diu and Somnath beach, Veraval) were compared with the pre-lockdown era, 2013. The lockdown phase favored the natural restoration of the beaches and showed infinitesimal values of the parameters tested when compared with the pre-lockdown regime. However, the new normal situation in 2021 opened up the accessibility of these beaches to the tourists and pilgrims resulting in significant changes of water quality. The release of diluted sewage mixed with freshwater from the Somnath town to the sea has led to the drastic change in beach water quality. The mean cadmium concentration increased drastically in beach waters (Ghoghla: 1.35, 0.28 and 7.09 μg/L; Somnath: 0.45, 0.28 and 0.58 μg/L) during pre-to-post lockdown, respectively. However, post-lockdown resulted in the rise of toxic heavy metals in the sediments of Somnath beach but Ghoghla beach remained to be pristine which may be due to the Blue Flagship status. The total number of marine bacteria was higher during 2013 and 2021 when compared during lockdown describing greater human interventions. For instance, Vibrio spp. count in Ghoghla beach water during pre-lockdown phase was 7733 CFU/mL and this value reduced to 70 and 5 CFU/mL in the lockdown and post-lockdown phases. Interestingly, the diversity of planktonic and benthic components showed a different trend from pre-to-post lockdown due to significant change in the inorganic nutrients and metal bioaccumulation. To our knowledge, this will be the first comprehensive assessment to report the environmental and ecological health of Ghoghla beach and Somnath beach during the pre-to-post lockdown.

“…In addition to this, Oluwatosin et al [15] reported that the sub-lethal exposure showed reduction in growth with an increase in PbCl 2 concentration and the specific growth rate in the control was higher than other treatments with PbCl 2 . In another development, Han et al [16] found that growth and hematological parameters determined decreased with increasing arsenic concentration, while the concentration of plasma components measured increased. Also, fish exposed to 10, 50 and 100µgHg/L showed a significant decrease in growth rates as from days 14 to 35 [17] .…”

Persistent environmental pollutants over the years have had deleterious effects on aquatic biota and by extension other living organisms on earth. The present study attempted to determine the roles of some vitamins in reducing the effects of Lead (Pb) in terms of some observed differences in the growth parameters of Clarias gariepinus. C. gariepinus fingerlings (whose initial weight ranged from 3 to 11g) were subjected to sub-lethal concentrations of Pb (00, 26mg/L, 44mg/L, 61mg/L and 79mg/L). Vitamins A, C and E at 26mg/L in each case were administered across all bud, respectively. The growth parameters measured every 7 th day for a period of 12 weeks were standard lengths (SL), total lengths (TL) and weight. The following treatment groups were used: Pb (Pb only), PbVA (Pb+vitamin A), PbVC ((Pb+vitamin C) and PbVE (Pb+vitamin E) with four treatments (T1-T4) and replicates in each case. The specific growth rate (SGR), weight gain (WG) and percentage weight gain (% WG) were calculated from the weight. From the results: The highest SL in the Pb only, PbVA, PbVC and PbVE treatments were 14.90cm, 12.60cm, 12.30cm and 19.40cm, respectively. The highest TL in Pb only, PbVA, PbVC and PbVE, respectively were 17.60cm, 14.10cm, 13.90cm and 22.30cm. The highest weight value in the Pb only, PbVA, PbVC and PbVE were 36.09g, 21.64g, 23.48g and 83.26g, respectively. T1 and T3 had the highest%WG and SGR in comparison to the control in both Pb only and PbVE treatment groups. In the PbVE there was general improvement in weight values in all treatments. The outcome of this research suggests that vitamin E can attenuate the effects of Pb toxicant and out-perform the un-exposed samples; hence, optimized concentration of the vitamin can serve as remedy in heavy Pb intoxication.

“…Continuous exposure of less than one-week-old guppy (Poecilia reticulata) to phthalate for 14-91 days reduced body weight and body length (131). In juvenile starry flounder (Platichthys stellatus), daily length and weight gain, and condition factor decreased following 2 and 4 weeks of aqueous exposure to arsenic (159).…”

Experimental Approaches for Characterizing the Endocrine-Disrupting Effects of Environmental Chemicals in Fish

Increasing industrial and agricultural activities have led to a disturbing increase of pollutant discharges into the environment. Most of these pollutants can induce short-term, sustained or delayed impacts on developmental, physiological, and behavioral processes that are often regulated by the endocrine system in vertebrates, including fish, thus they are termed endocrine-disrupting chemicals (EDCs). Physiological impacts resulting from the exposure of these vertebrates to EDCs include abnormalities in growth and reproductive development, as many of the prevalent chemicals are capable of binding the receptors to sex steroid hormones. The approaches employed to investigate the action and impact of EDCs is largely dependent on the specific life history and habitat of each species, and the type of chemical that organisms are exposed to. Aquatic vertebrates, such as fish, are among the first organisms to be affected by waterborne EDCs, an attribute that has justified their wide-spread use as sentinel species. Many fish species are exposed to these chemicals in the wild, for either short or prolonged periods as larvae, adults, or both, thus, studies are typically designed to focus on either acute or chronic exposure at distinct developmental stages. The aim of this review is to provide an overview of the approaches and experimental methods commonly used to characterize the effects of some of the environmentally prevalent and emerging EDCs, including 17 α-ethinylestradiol, nonylphenol, BPA, phthalates, and arsenic; and the pervasive and potential carriers of EDCs, microplastics, on reproduction and growth. In vivo and in vitro studies are designed and employed to elucidate the direct effects of EDCs at the organismal and cellular levels, respectively. In silico approaches, on the other hand, comprise computational methods that have been more recently applied with the potential to replace extensive in vitro screening of EDCs. These approaches are discussed in light of model species, age and duration of EDC exposure.
