Blood parameters are important indicators for assessing the health status of living organisms subject to changing environment. Blood parameters (Hb%, TEC, TLC, ESR, PCV, MCH, and MCV) of Heteropneustes fossilis exposed to lead were investigated at different time intervals. Acclimatized specimens were divided into four groups: Group-A (Control), Group-B (2.25 ppm), Group-C (2.65 ppm), Group-D (2.85 ppm) of Pb and examined at 7, 14, 21 and 28 days' time intervals. The maximum impact of the treated metal was observed on ESR (Erythrocyte Sedimentation Rate) [1.80 mm/h (Control) to 2.90 mm/h at 2.85 ppm of lead] during maximum time exposure (28 Days) whereas PCV (Packed Cell Volume) showed a fall [44.00 % (control) to 28.00% (2.85 ppm] at 28 Days pe (post-exposure). The other parameters also showed changes in their values when exposed to lead being highest at 2.85 ppm doses during maximum time exposure (28 Days). The above findings indicate that lead adversely affects the blood physiology as reflected in hematological values. INTRODUCTION: Water is an integral constituent of all living things, and it is the universal biological solvent. Modern industrial and agricultural techniques require the use of many million tons of fertilizers, heavy metals and pesticides. These effluents find their way into aquatic systems through surface runoff from industries or as a result of the discharge of these wastes into streams and rivers. They pose a constant threat to non-target organisms such as fish and insects and tend to bio-concentrate the inorganic and industrial wastes 1, 2 .

“…The calculation of the hematocrit value and hemoglobin level reflects the oxygen that carries the blood's carrying power. A low concentration of hematocrit can cause damage or defects in the osmoregulation process, while a high value indicates an increased demand for oxygen or hypo-osmotic conditions (Oğuz, 2015;Zainuddin et al, 2017). The contamination of the water by detergent residues affects the local ecosystem with stable properties in the sediments, ease of absorption, and accumulation in the body tissue of fish, relevant to human health implication.…”

The high concentration of detergent in the aquatic ecosystem potentially affects the physiological condition of the fish by disrupting the respiration process and changing the concentration of blood components and chemistry. The purpose of this study was to determine the condition of the hematological parameters of tilapia (Oreochromis niloticus) exposed to wastewater from the laundry industry. Each treatment was stocked with five fish per aquarium (50 x 30 x 30 cm). This study used a completely randomized design (CRD) technique with six treatments and three replications: P0 (0%) as a control, P1 (1%), P2 (2%), P3 (3%), P4 (4%) and P5 (5%) with each treatment exposed to a specific concentration of wastewater and residues. The results showed that the hemoglobin levels of treatments were decreasing, with the lowest mean of hemoglobin level found in the P2 (7.05 gr%), and the lowest concentration on the 30th day was 7.71 gr%. There were no significant effects of wastewater to the number of erythrocytes and leucocytes among treatments (P>0.05). While there were increasing levels of hematocrit, the largest mean level was found in the P4 treatment with a value of 24.11%, and the largest mean on the 20th day of observation showed a value of 23.51%. Wastewater from the laundry industry can affect the hematological condition of tilapia by decreasing the hemoglobin concentration and increasing the hematocrit levels above the normal condition.

“…In general, heavy metals have a strong in uence on the regulation of monovalent ions, causing net ion drop in hyperosmoregulating freshwater sh (Wilson and Taylor 1993;Adhim et al 2017;Handayani et al 2020) and net ion uptake in hypoosmoregulating marine sh (Stagg and Shuttleworth 1982).

“…Fish exposed to waterborne Cd may experience a variety of deleterious effects, including changes in respiration (Sha et al 2001), decreased growth (Okorie et al 2014), alteration in plasma ion regulation (McGeer et al 2000), hematological abnormalities (Adhim et al 2017;Handayani et al 2020), and enzyme activity (Nursanti et al 2017;Ma'rifah et al 2019).

Tilapia exposed to two different Cd concentrations in freshwater had varying levels of Cd in their gills, with fish exposed to 2 mg/L of Cd having a higher Cd level than fish exposed to 1 mg/L of Cd. The higher Cd level exposure caused considerable metabolic acidosis (lower pH and higher pCO2) and inhibited gill carbonic anhydrase. Fish exposed to higher Cd levels had lower osmolality, levels of plasma Cl− and K+ but constant levels of Na+. All hematological parameters tested in this study, including red blood cells, hemoglobin, hematocrit, and mean cellular hemoglobin concentration hematocrit, decreased as a result of increased Cd exposure. This is consistent with the pO2 measurement, which indicates that fish exposed to greater levels of Cd had a considerable reduction in pO2.
