“…The occurrence of testicular normal architecture disruption (Das, 1988;Kumari and Dutt, 1991), lobular degeneration (ElEbiary et al, 2013;Sangalang and O'Halloran, 1972), proliferation of interstitial tissue (El-Ebiary et al, 2013), blood cell infiltration (ElEbiary et al, 2013), reduction of germ cells (Kumari and Dutt, 1991) and disappearance of spermatozoa inside the cysts (Kumari and Dutt, 1991) agrees with that observed for other fish species exposed to Cd through water or diet. Moreover, the use of increasing doses in Fig.…”

“…The decreases in sperm motility (Chyb et al, 2001;Dietrich et al, 2010;El-Ebiary et al, 2013) and count (El-Ebiary et al, 2013) that were documented after Cd exposure indicate the vulnerability of sperm to metal exposure.…”

“…The use of Cd in batteries, pigment and plating industries can be the source of Cd in the Buriganga River water. A study (El-Ebiary et al, 2013) found the highest mortality relation as a consequence of high dose of Cd on red tilapia which also affects on the decrease of sperm number.…”

The hydrochemistry and pollution status of tannery effluent as well as the Buriganga River were studied. The water quality parameters namely temperature, pH, salinity, TDS, EC, DO, COD, Cr, Cd, Ni, Cu and Zn of tannery effluent were 22.8-31.5 o C, 7.4-10.6, 3920-6280 mg/l, 4680-7220 mg/l, 7070-10810 µs, 0.3-1.1 mg/l, 1020-3800 mg/l, 7.7656 mg/l, 0.0198 mg/l, 0.2070 mg/l, 0.0304 mg/l and 0.3021 mg/l, respectively whereas in water of the Buriganga River were 22.0-31.6 o C, 6.2-7.8, 69-642 mg/l, 97-871 mg/l, 146-1309 µs, 1.1-4.1 mg/l, 140-800 mg/l, 0.0306-0.2163 mg/l, 0.0018-0.0162 mg/l, 0.0663-0.2486 mg/l, 0.0112-0.0238 mg/l and 0.0878-0.2948 mg/l, respectively. According to the statistical analysis Salinity, EC, TDS, COD, Cr, Cd, Cu and Zn show positive correlations with each other and negative correlations with Temp. and DO. Ecological risk factor shows that Cr is the highest risk metal for ecosystem. The hydrochemistry has been revealed that the water is not safe for aquatic lives.

“…The observed concentrations of Cd are above the danger level in Khiru river [89]; Balu river (0.003-3.30 mg/l) [92] Meghna river [91] Buriganga river [96] Turag river [12] as well as in groundwater from Noakhali [32] and Mohammadpur [70]. Intense mortality rate of red tilapia has been observed due to the higher intake of Cd and it also has an effect on the decreasing of sperm number [115]. The intake of Cd over the permissible level through water or food causes acute and chronic illness for human and also treats as a carcinogenic agent [116].…”

Environmental analysis does not become properly meaningful unless follow the standard procedure in sampling, preserving and also in analysis. This study investigates different studies on surface and groundwater pollution and discusses their findings along with impacts on environment, human health and aquatic ecosystem demolition. Fresh water is a vital need for drinking, household, agricultural and industrial use. Fresh water availability is shrinking worldwide due to imprudent use. Abound availability of fresh water in Bangladesh is now polluting due to unwise dumping of industrial, household, agricultural and municipal wastes. Water body in urban arena is severely polluted rather than rural part. The over concentration of DO, BOD, COD, EC, TDS, Cr, Cd, Pb was observed in Dhaka region. The highest arsenic concentration was found in the ground water of Lakshimpur. The main sources of pollution in industrial cities are anthropogenic sources like untreated industrial effluent and municipal wastes whereas in rural part the main sources of pollution are agricultural and naturogenic. Transboundary impact also intensifies some river water pollution. Government approved the policies, ordinance, acts and laws however, due to lack of proper implementation and monitoring water pollution problem increasing day by day.
