Assessment of heavy metals contamination and human health risk in shrimp collected from different farms and rivers at Khulna-Satkhira region, Bangladesh

Abstract

This study is aimed to assess the heavy metals contamination and health risk in Shrimp (Macrobrachium rosenbergii and Penaeus monodon) collected from Khulna-Satkhira region in Bangladesh. The results showed that the Pb concentrations (0.52–1.16 mg/kg) in all shrimp samples of farms were higher than the recommended limit. The Cd levels (0.05–0.13 mg/kg) in all samples and Cr levels in all farms except tissue content at Satkhira farm were higher than the permissible limits. The individual concentration of Pb, Cd, and Cr between shrimp tissue and shell in all rivers and farms were not statistically significant (P > 0.05). Target hazard quotient (THQ) and hazard index (HI) were estimated to assess the non-carcinogenic health risks. Shrimp samples from all locations under the current study were found to be safe for consumption, the possibility of health risk associated with non-carcinogenic effect is very low for continuous consumption for 30 years.

Patterns of trace metal bioaccumulation and trophic transfer in a phytoplankton-zooplankton-small pelagic fish marine food web

“…The slight increase in Zn BAF in fish is also consistent with the biomagnifying potential of Zn in marine fish food chains (Wang, 2002). Conversely, the higher Cd bioaccumulation we observed in zooplankton fractions (mainly composed of copepods and crustacean larvae) versus fish may be linked to efficient copepod Cd assimilation (Twining and Fisher, 2004) and the ability of crustaceans to accumulate high quantities of Cd in their exoskeleton (Sarkar et al, 2016).…”

Bioaccumulation of Some Heavy Metals on Silver-Cheeked Toadfish (Lagocephalus sceleratus) from Antalya Bay, Turkey

“…So the sediments could be the major sources of Pb contamination and the bottom feeders may directly affects with this deposited element in consequence to their feeding habitat (Garcia et al, 2010). Zn is the essential element for both human and aquatic organisms and they showed productive activity against Cd and Pb toxicity in biological organisms (Sarkar et al, 2016).…”

Analysis of Environmental Health Risk Exposure to Heavy Metals in Communities that Consume the BatissaViolaceacelebensis from Konaweha River, Indonesia

“…Another research showed that there were 29 fish species in South China Sea, they are ; 51-115.81 ng/g (Cd), 0.54-27.31 ng/g (Pb), 0.02-1.26 μg/g (Cr), 8.32-57.48 ng/g (Ni), 0.12-1.13 μg/g (Cu), 2.34-6.88 μg/g (Zn), 2.51-22.99 μg/g (Fe), and 0.04-0.81 μg/g (Mn) [7]. Moreover, heavy metals are also identified in river,Pb, Cr and Zn consentration in many fish samples exceed consumption limits [19], and it is contaminated by heavy metals in shrimp (Macrobrachiumrosenbergii and Penaeusmonodon) that are collected from Khulna-Satkhira area in Bangladesh with concentration; Pbthat is (0.52-1.16 mg/kg) and Cd that is (0.05-0.13 mg/kg) [20].…”
