“…As a result, the increasing demand of food safety has accelerated research regarding the risk associated with food consumption contaminated by heavy metals [7]. Excess amounts of heavy metals from anthropogenic sources that enter into the ecosystem may lead to geo-accumulation [8][9][10][11][12][13][14] and bio accumulation [4], which in turn pollute the environment and also affect the food chain and ultimately pose serious human health risks [15][16][17][18][19].…”

An experiment was conducted to study heavy metals bioaccumulation pattern in edible tissues of different farmed fishes and to assess human health risk through their dietary intake. Total 3 different species viz. grass carp (Ctenopharyngodon idella), silver carp (Hypophthalmichthys molitrix) and mrigel (Cirrhinus cirrhosis), and 3 dissimilar sizes of fish samples were collected from Muktagacha and Trishal area of Mymensingh district, Bangladesh during January 2018 and analysed for this study. Among the fish species, mean concentrations of Ca, Na and K were higher in mrigel; Mg and S contents were higher in silver carp and P content was higher in grass carp. As regards to heavy metals, mean concentrations of Pb (18.98 µg g-1), Ni (0.688 µg g-1) and Cu (15.197 µg g-1) were higher in mrigel; Cd (1.127 µg g-1), Cr (15.097 µg g-1) and Zn (36.023 µg g-1) contents were higher in grass carp, while contents of all metals were lower in silver carp. In context of size, both mineral nutrients and heavy metals bioaccumulation pattern in all species were higher in large size fishes. Similarly, metal pollution index values for all species of fish samples showed a sequence- large size> medium size> small size, which indicates that heavy metal bioaccumulation pattern was directly related to the size and age of fishes. The study results revealed that the daily intakes of Pb and Cd for all species and sizes of fish samples were higher than that of upper tolerable intake level. Target hazard quotients (THQ) values for Pb and Cr surpassed 1.0 for both male and female, which indicate that the exposed populations are in a level of concern interval. But in context of other heavy metals, these farmed fishes can assume as safe for human consumption.

“…There is a progressive increase in industrial as well as urban wastes and effluents due to the rapid industrialization and urbanization. Such waste products and effluents are discharged into the rivers without any kinds of treatment, which have a significant contribution to the heavy metal content of river water and sediments [8][9][10][11][12][13]. These heavy metals and other toxic substances, which often lead to decrease in number of fish species in rivers and canals of Bangladesh.…”

Fifteen (15) fish species were collected from three (3) locations of the Brahmaputra River to determine heavy metals content in fish flesh, and to assess potential human health risk through consumption of those fishes. The contents of heavy metals in aqueous extract of different fish species were determined by an atomic absorption spectrophotometer (AAS) at the Department of Agricultural Chemistry, Bangladesh Agricultural University, during the period from March to June, 2018. The concentrations of Mn, Zn, Cu, Pb, Cd and Cr in different fish species ranged from 41.70-376.62, 38.98-279.08, 3.19-47.91, 2.20-3.73, 0.19-1.20 and 0.59-2.40 mg kg-1, respectively. The study results revealed that the edible portion of fish species of the river contained reasonably higher amount of Mn, Zn, Pb, Cr and Cu compared to some other previous studies carried out elsewhere with freshwater fishes. Among the fish species, mola (Amblypharyngodon mola) showed the highest metal pollution index (20.12) followed by chela (Salmophasia bacaila) (17.72), chanda (Chanda nama) (16.78) and chingri (Macrobrachium sp.) (15.83), while baim (Macrognathus aculeatus) exhibited the lowest (6.79). The calculated daily metal intake for Pb, Mn and Cd for both male and female were higher than that of upper tolerable intake level, which indicates consumption of common fishes of this river, is not safe. Similarly, target hazard quotient (THQ) values for Mn surpassed 5.0 for both male and female, and the same value for Pb also surpassed 5.0 for female indicate that the exposed population are unsafe. The study results also revealed that all individual THQ values of other metals for both male and female surpassed 1, which means exposed population are in level of concern interval. In Bangladesh freshwater river fishes are more popular than farm fishes. However, the study results recommend to aware people about heavy metal contents before consuming fish species of a polluted river system.

“…Heavy metal contamination in the soil-water-plant ecosystem is of great concern because of its possible influence on the food chain (Mmolawa et al, 2010;Zakir et al, 2012). In the soil system, pollution by toxic metals is due to both natural processes, such as weathering of minerals, and anthropogenic activities related to industry, agriculture, burning of fossil fuels, vehicular emissions, mining and metallurgical processes and their waste disposal, as is the case in Nigeria (Human Rights Watch Staff, 2013).…”

A pot experiment was conducted to study the potentials of Kenaf (Hibiscus cannabinus L.) as a Copper (Cu) phytoaccumulator at different levels of artificial contamination. Copper was applied as cupric sulphate (CuSO4.5H2O) and the treatments were 0, 50, 100 and 150 mg kg -1 of Cu. Kenaf was grown in each of the treated pots for 10 weeks, following which, leaf, stem and root samples were collected and analysed for Cu contents. The soil was analysed for physicochemical properties [viz. pH, electrical conductivity (EC), organic carbon (OC), exchangeable acidity (EA), exchangeable cations (Ca 2+ , Mg 2+ , Na + , K + ) and extractable and total Cu contents) before treatments/contamination and after harvesting. Kenaf showed symptoms of toxicity at 100 and 150 mg kg -1 treatments of Cu. It was observed that, compared with the levels of contamination of Cu, the concentration in kenaf was generally insignificant; thus, the concentration reduction in the soil at one cycle of cropping may not berealistic. Copper treatments at different levels significantly changed soil pH and EC. Therefore, more cycles of growth are needed to effectively remediate Cucontaminated soils using Kenaf as Cu phytoaccumulator.
