Freshwater mollusks are employed as bioindicators for the assessment of water quality in biomonitoring studies since the water quality of natural resources is crucial for humans. The freshwater snail species known as Viviparus contectus (Viviparidae: Gastropoda) is one that people eat. Here, the levels of heavy metals (Cd, Cr, Pb, As, Zn, and Cu) in water and V. contectus samples were determined. An Inductively Coupled Plasma Atomic Emission Spectrometer (ICP-AES, Spectro Arcos, vertical plasma) was used for the analysing the heavy metal concentrations in water and freshwater snail samples. The results of the current investigation demonstrated that freshwater snails accumulated metals in their water and soft tissues in the following orders: Pb > Cr = Zn = Cu = Cd = As and Zn > Cu > Pb > Cd > As = Cr. Autumn was the time of year when higher amounts of heavy metals (As, Cr, Cu, Zn, and Hg) were found. Pb content in the freshwater snail samples was strongly impacted by seasonal fluctuations (P 0.05). For adults, the EDI (estimated daily intake) values were lower than the TDI (tolerable daily intake) values, and the HI (hazard index) values were below 1. Freshwater snail samples had Zn and Pb levels that were over the FAO/WHO, Turkish Food Codex, JECFA, and EC limit values. Except for Pb, the water study shows mean metal concentrations below the USEPA, Turkish Pollution Control Regulation, and World Health Organisation maximum allowed levels. Aquatic ecosystems were negatively impacted by anthropogenic activities overall, and this study can provide a helpful data set for investigations on metallic contamination in water bodies and biomonitoring in freshwater ecosystems.

Fishes are largly used for the assessment of aquatic environment quality and are accepted as bioindicators of environmental pollution. This study evaluated haematological and biochemical responses of Capoeta trutta captured in Munzur River, Tunceli, Turkey. Blood and biochemical parameters (Sodium (Na), Potassium (K), Calcium (Ca), Phosphorus (P), Chlorine (Cl) and Iron (Fe)) were determined. The values of Red Blood Cell (RBC) Haemoglobin (Hb), Haemotocrit (Ht), Haemoglobin Concentration (MCHC), Platelet Count (PLT), Mean Platelet Volume (MPV), Plateletcrit (PCT), Platelet Distribution Width (PDW) from examined haematological parameters were found as 0.67+/-0.09 10(12) L(-1), 13.5+/-0.90 g dL(-1), 14.78+/-0.19%, 218.40+/-4.29 fL, 194.75+/-15.36 pg 108.52+/-1.09 g dL(-1), 34.12+/-5.89 10(9)L(-1), 11.92+/-1.65 fL, 0.061+/-0.01% and 19.77+/-1.71 fL, respectively. The values of Fe, Cl, P, Ca, K and Na from examined biochemical parameters were determined as 91.75+/-28.27 g dL(-1), 92.00+/-4.02 mmol L(-1), 13.20+/-1.26mg dL(-1), 11.65+/-0.74 mmol L(-1), 1.30+/-0.21 mmol L(-1) and 132.5+/-3.90 mg dL(-1) respectively. Observation of blood parameters allows the most rapid detection of changes in fish after the exposure to xenobiotics. It can conclude that hematological and biochemical parameters could be ranked as possible biomarkers of pollution.
