“…Expectedly, toxicological effects of Na-pCp on aquatic organism H. holandrii increased with the concentration and the duration of exposure, which was confirmed in other studies on aquatic organism, such as, molluscs: Mytilus galloprovincialis [19], Crassostrea gigas, Mytilus edulis, Ruditapes philippinarum and Chlamys farreri [16], crustaceans Palaemonetes pugio [18], and fish: Mystus vittatus [12] and Aristichthys nobilis [16].…”

“…pCp can be metabolized by numerous aquatic and soil microorganisms, but environmental conditions are usually unfavourable for biodegradation [7]. The histopathological research has shown high degree of pathological lesions observed in various organs, e.g., gills, liver, intestine and kidney of the fish Mystus vittatus caused due to excessive accumulation of phenolic compounds [12]. Furthermore, pCp also act both directly or indirectly on the metabolism of lipids as shown on coelomocytes earthworm Eisenia fetida [13], carbohydrates and proteins, as well as on the ion transport across the cell membrane [14].…”

The pollution of aquatic ecosystems by sodium pentachlorophenolate (Na-pCp) has assumed serious proportions due to their toxicity and accumulative effect in organisms and environment. The objective of this experimental study was to examine and quantify the histopatological effects of Na-pCp on the structure of hepatopancreas and gill, as two most important organs targeted by phenol entries, in the freshwater snail, Holandriana holandrii. Results indicate serious structural changes in tissue and epithelial cells of both organs and were accelerated with increase of Na-pCp concentrations and more pronounced related to exposed period. In hepatopancreas, tubular lumen, vacuole surface and number per tubule, exudate area in the tubular lumen, all increased with increase in concentration. Opposite trend of decreased height was observed for digestive and basophil cells. Significant gill structural changes appeared as a progressive necrosis at epithelial cells and the epithelial lining was interrupted, while connective tissue exhibited vacuolization, formation of large irregular spaces and damaged chitinous rods. Histomorphometrical approach in quantification of toxicant effects on the organism tissue could be used in legislative prevention of hazardous effects in freshwater ecosystems and H. holandrii may serve as a reliable and sentinel indicator of freshwater deterioration.

“…Blood allows the body to mobilize defenses as soon as an injury or disease occurs (Adewumi et al, 2018). Research in the field and in the laboratory has clearly demonstrated that aquatic contaminants alter hematological parameters in animals involved in the study, including fish (Adewumi et al, 2018;Amaeze et al, 2020;Muthukumaravel et al, 2021a;Muthukumaravel et al, 2021b;Morshedi et al, 2022;Naguib et al, 2022). In the current study, a reduction in RBCs, hematocrit, hemoglobin, and thrombocytes may be caused by a disturbed hematopoiesis process as black sand concentrations rise.…”

Trace elements such as titanium, zirconium, thorium, and uranium, are found in black sand (BS) after weathering and corrosion. Precious metals are not the only valuable elements in black sand, rare earth elements are also found. The aquatic life in lakes and reservoirs is negatively affected by lithophilic elements such as lithium, uranium, and tin. Accordingly, intensive experiments were conducted on Nile tilapia (Oreochromis niloticus) after exposure to isolated black sand. Blood biomarkers, antioxidant balance, morpho-nuclear erythrocyte’s alterations, and histopathological signs have been investigated after fish exposure for 15 days to a 6.4 g BS/kg diet, 9.6 g BS/kg diet, and 2.4 g BS/kg diet. The blood profile, including platelets and white blood cells, was pronouncedly decreased as a result. Functions of the liver and kidneys were impaired. An increase in serum-antioxidant enzymes such as catalase activities and superoxide dismutase was recorded. Also, exposure to black sand induced cellular and nuclear abnormalities in the erythrocytes. In conclusion, the black sand isolated from the Red sea beach influenced Oreochromis niloticus’s hematology, biochemistry, and antioxidant parameters. Poikilocytosis and RBC nuclear abnormalities were also associated with exposure to black sand. The resulting erosion of rocks and rocks’ access to water forces us to consider the seriousness of climatic change on the aquatic ecosystem.

“…Fish gills contribute to the key function of respiration and osmoregulation. Proximal contact of this organ with the external environment harboring various contaminants [ 23 , 24 ] make it a target organ for the reported uptake of toxicants and subsequent pathological manifestations. Since the rate of oxygen consumption has been considered as a true index of the overall metabolic state of animals, the change in respiratory activity can be used as an indicator of stress in animals exposed to toxicants [ 25 ].…”

Background: The current study was performed aiming to evaluate possible changes in the effect on oxygen consumption, hematology and gill histopathological parameters in fish (Chanos chanos) upon exposure to sublethal concentration of the metalloid arsenic. Methods: Bioassay tests were conducted for determining the LC50 values of arsenic for 96 h. Oxygen consumption in control and arsenic-exposed fish was estimated using Winkler’s method. Red blood corpuscular (RBC) count was examined with a Neubauer counting chamber under a phase contrast microscope. Hemoglobin (Hb) was estimated following the acid hematin method. Histopathological studies were carried by processing and staining the gill tissues with hematoxylin and eosin in accordance with standard histological techniques. They were then subjected to examination under a scanning electron microscope. Results: Chanos chanos exposed to 1/10th of LC50 (24.61%) for a period of 30 days exhibited a maximum decline in the rate of respiration, followed by a decline in RBC and Hb above 45.59% and 51.60%, respectively. Significant toxic lesions encompassing fused gill lamellae, detached gill epithelium, hyperplasia and hypertrophy of respiratory epithelium became heavy handed on the 30th day. Conclusion: Information synthesized from our study serves to be useful in monitoring and managing (As) contamination in the aquatic environment.
