“…Heavy metals and metalloids, when occurring at higher concentrations, become severe poisons for all living organisms including human. For example, an excessive amount of Hg, As, Pb, and Cd elements could be detrimental to the living cells, and a prolonged exposure to the body can lead to illness or death [15]. Among the metals, Hg is the most toxic metal in our environment.…”

The Karnaphuli River estuary, located in southeast coast of Bangladesh, is largely exposed to heavy metal contamination as it receives a huge amount of untreated industrial effluents from the Chottagram City. This study aimed to assess the concentrations of five heavy metals (As, Pb, Cd, Cr and Cu) and their bioaccumulation status in six commercially important fishes, and also to evaluate the potential human health risk for local consumers. The hierarchy of the measured concentration level (mg/kg) of the metals was as follows: Pb (13.88) > Cu (12.10) > As (4.89) > Cr (3.36) > Cd (0.39). The Fulton’s condition factor denoted that fishes were in better ‘condition’ and most of the species were in positive allometric growth. The bioaccumulation factors (BAFs) of the contaminants observed in the species were in the following orders: Cu (1971.42) > As (1042.93) > Pb (913.66) > Cr (864.99) > Cd (252.03), and among the specimens, demersal fish, Apocryptes bato appeared to be the most bioaccumulative organism. Estimated daily intake (EDI), target hazard quotient (THQ), hazard index (HI) and carcinogenic risk (CR) assessed for potential human health risk implications suggest that the values were within the acceptable threshold for both adults and children. However, calculated CR values indicated that both age groups were not far from the risk, and HI values demonstrated that children were nearly 6 times more susceptible to non-carcinogenic and carcinogenic health effects than adults.

“…Being the top consumers, fishes can have heavy metals in four routes via food consumption, water uptake (gills), consumption of nonedible particles and through skin absorption. The absorbed heavy metals accumulate in the different body organs especially in the liver, kidney and gills prior to being eliminated or stored (Azaman et al 2015). Accumulation of heavy metals may reduce fish appetite and metabolic activities that leads to hamper growth and development (Javid and Saeed, 2010) and can be serious hazard when transferred to humans by fish consumption (Rahman et al 2014).…”

Labeo rohita was sampled to determine the contamination levels of chromium, lead, nickel, copper and manganese from wild (Trimmu and Balloki Headworks) and controlled fish ponds at Ravi Campus (UVAS) from September to December, 2013. Sampled fish were blotted dry, weighed and liver and intestine were removed to study histology and metals concentration. Chromium seems ubiquitous and was detected in all the water samples as well as liver and intestinal tissues of experimental fish. Its level was lowest in water samples and fish organs in samples collected from UVAS fish ponds while the highest in samples collected from Balloki Headworks, the main recipients of waste from Lahore city. Fish liver depicted Chromium (Cr) only but the intestine revealed the presence of Nickel (Ni), Lead (Pb), Manganese (Mn) and copper (Cu) too. Cadmium was below the detectable limit in all water and tissues (liver, intestine) of sampled fish. Heavy metals load and their range induced pathological alterations, infiltration and necrosis in liver and intestinal tissues. Canonical discriminate analysis of Cr, Cu, Mn, Ni, Pb and Cd and the extent of histopathological changes differed significantly among localities establishing an appropriate link with living media and their vertical flow in fish.

defined the concentration of metals in Kerteh and Paka River water and their potential health risk towards human. 54 water samples were collected and analyzed using ICP esults revealed that most of the stations in Kerteh River gave the higher concentration Pb compared to Paka River. However As, Cr and Malaysia standard for all stations in both rivers. Cd, Cu, Zn, Co and Ni were standard permissible levels during the sampling component analysis (PCA) revealed that both geogenic and anthropogenic sources were metals contamination in both rivers. Moreover, risk assessments for all safe limits, except for As in the Kerteh River for both adult and child for both genders.
