Assessment of Selected Heavy Metals Concentration In Different Brands of Fish Feed Available In Bangladesh

Abstract

The paper reports the findings on the concentrations of heavy metals in ten different fish feed by using Atomic Absorption Spectrometer. The level of heavy metal concentrations (dry weight) in the fish feed ranged from 1.17 to 2.0, 2.33 to 4.67, 5.17 to 21.67, 106.67 to 363.3, 3.5 to 7.16, 3.83 to 21.2, 56.7 to 141.6 and 2.1 to 16.49 mg/kg of Cd, Co, Cu, Fe, Ni, Pb, Zn and Cr respectively. The concentrations of Fe, Pb, Co, Cr in different brands of fish feed exceeded the maximum permissible limits recommended by FAO/WHO and EU whereas the concentrations of Cd, Cu, Ni, Zn were within acceptable limits.

Assessment of Human Health Risks Associated with Heavy Metals Accumulation in the Freshwater Fish Pangasianodon hypophthalmus in Bangladesh

“…Other metal loads positioned below the acceptable limits of FAO/WHO(1984),WHO (1985). The Cd and Cu concentrations of the tested feed found to show similar patterns as described bySaha et al (2018) (listed in table 8). Lower values of Pb and Cr in the studied fish feeds supported by Mo et al (2019), Anhwange et al (2012), Fallah et al (2011).…”

“…In this study, Ni contents of feed samples in the studied locations exceed used as feed additives, which could be the cause of higher accumulation of copper in pangas (Burridge et al, 1999). The extreme contamination of nickel in the fish feed samples was observed in the present study where this high value may enter the fish feed through the raw materials (Saha et al, 2018). Figure 4 (i-iv) demonstrates the estimated daily intake (EDI) (mg/day) of heavy metals due to their intake by pangas.…”

“…Different works have been done on heavy metals contamination in fish feed samples (Fallah et al, 2011;Anhwange et al, 2012;Saha et al, 2018, Sabbir et al, 2018Mo et al, 2019. In this study, Ni contents of feed samples in the studied locations exceed used as feed additives, which could be the cause of higher accumulation of copper in pangas (Burridge et al, 1999).…”

“…Different works have been done on heavy metals contamination in fish feed samples (Fallah et al, 2011;Anhwange et al, 2012;Saha et al, 2018, Sabbir et al, 2018Mo et al, 2019. In this study, Ni contents of feed samples in the studied locations exceed the permissible levels of EC ( 2003).…”

Assessment of toxic and essential metals in fish feed ingredients available in different areas of Bangladesh

“…Bangladesh is widely recognized for producing leather from raw hides and skins and the tanning industries are highly reliable to chrome tanning method which is liable for chromium pollution both in liquid and solid waste. Moreover, groundwater is polluted severely due to arsenic contamination in many regions of this land [4,5]. Industrial disposals and mining extraction can be a potential source of heavy metal exposure in the aquatic ambiance [6].…”
