“…The biomonitoring wild aquatic organisms such as fishes, is fundamental to indicate quality and stability of the environment Moyson et al, 2016;Ramsdorf, Vicari, De Almeida, Ferreira Artoni, & Cestari, 2012;Savorelli et al, 2017;Vajargah, Yalsuyi, & Faggio, 2018). In this aspect, fishes are appropriate as bioindicators of environmental conditions due to their position in the trophic chain and their sensitivity to low concentrations of genotoxic substances (Van Der Oost, Beyer, & Vermeulen, 2003).…”

Fish erythrocytes are very sensitive to environmental pollution because they exhibit pathological alterations before appearance of other external symptoms, may be used as reliable toxicity bioindicators. Microscopic analysis can be a useful tool in early detection of alterations in erythrocyte morphology due to different environmental stressors, and in predicting organism's possible response ways. This study aims to evaluate the toxicity of a polluted freshwater lake on the erythrocytes of crucian carp fish, Carassius carassius, using digital light microscopy (DLM). Scanning DLM micrographs revealed the presence of nuclear and cytoplasmic abnormalities like micronucleus, nuclear buds, lobed nucleus, deformed nucleus, vacuolated cytoplasm, and echinocyte in the erythrocytes of crucian carp fish from a polluted lake. The obtained results substantiate that computation of erythrocyte morphological damages as biomarkers of exposure, through digital light microscopy software, can be effectively used as a toxicological tool.

“…Certain metals, such as Cu, Zn, Mn and Cr, play important roles in different physiological processes and are essential for living organisms; however, these metals become toxic at higher concentrations [8][9][10]. Other metals, such as Hg, Cd, Pb and Ni, exert toxic effects even when found in trace amounts [11][12][13][14].…”

Metal pollution of the aquatic environment is of global concern because metals are ubiquitous and can be accumulated in natural habitats as well as in organisms through the food chain. Accumulated metals are capable of inducing toxicity in living organisms, altering their reproductive success, behavior, immune response and biochemical processes. We examined the correlation between the concentrations of 9 metals (As, Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn) in the whole body of the river snail Viviparus acerosus, river water and sediment from three Serbian rivers with different levels of metal pollution, the Danube, Tisa and Velika Morava. Data about water quality showed that the concentrations of As, Cr, Fe and Ni were highest in the water of the Danube and of Cu, Mn and Zn in the water of the Velika Morava River. The concentrations of As and Mn were highest in the Danube River sediment, of Cd, Cu, Fe, Pb and Zn in the Tisa and of Cr and Ni in the sediment of the Velika Morava. The concentrations of all of the examined metals, except for Cu, were highest in snails from the Velika Morava. Correspondence analysis showed stronger correlations between metal concentrations in snails and the river sediment than between snails and river water. Several correlations between metal concentrations in snails and river sediment and water were established by Pearson's correlation test. The concentrations of metals in snail bodies were affected to a greater extent by the river sediment than by the river-water metal content. We conclude that V. acerosus has great potential as a bioindicator species of metal pollution in freshwater basins.

“…Unfortunately, HM are non-biodegradable and could deteriorate fish growth and health (Fazio et al 2014;Savorelli et al 2016;Abdel-Tawwab et al 2013. Thus, scientific methods for HM removal and/or detoxification are essential to improve the health of the fish inhabiting HM-stressed environment.…”

Heavy metal (HM) pollution is one of the major problems that adversely affect the aquatic ecosystem and inhabiting biota. Heavy metals adsorption by low-cost adsorbents is one of the techniques used for HM removing from polluted water. In the present study, agricultural wastes (AW), i.e., rice straw, sugarcane bagasse, and maize stalks, were washed with distilled water, dried in a dry-oven, cut into small pieces (\0.5 cm long), and immersed at 1.0 g/L in aquaria containing synthetic mixture of lead (Pb), cadmium (Cd), copper (Cu), and zinc (Zn). Nile tilapia, Oreochromis niloticus (L.), fingerlings (25.2 ± 0.88 g) were stocked at a density of ten fish per 100-L aquarium for 72 h, during which fish were fed on a fish diet containing 25% crude protein ad libitum twice daily. Samples of water, AW, and fish were collected at different times to determine HM concentrations. The HM removal from polluted water was depending on the type of the metal ions, AW, and the contact time. However, HM concentrations in aquaria waters of all AW treatments decreased significantly by increasing contact time up to 24 h after which their concentrations were almost the same. Concentrations of waterborne Pb, Cd, Cu, and Zn in AW-containing aquaria were significantly lower than those of AW-free aquaria. The presence of any AW reduced significantly HM concentrations. In AW-free aquaria, HM-exposed fish accumulated more HM in their body than those reared in AWcontaining aquaria. The results of this experiment showed that all AW had the capability to remove HM levels from the polluted water and reduce their bioaccumulation in fish body. However, rice straw was the more efficient adsorbent for all metals.
