Accumulation of lead in the muscle of brackish water fish (Boleopthalmus dussumieri)

Abstract

Lead is highly toxic, impairing biological functions of aquatic animals. In vitro, static test was performed to find out the accumulation of lead in the muscle of brackish water fish (Boleopthalmus dussumieri). Fish were maintained in experimental aquaria with lead nitrate solution having known lead concentration of 1.48 and 14.8 mg/l, respectively. The experiments were performed in triplicate. Two fishes from each exposed aquarium were sampled on zero hour, 96 hours and 192 hours. Muscle was removed and processed prior to analysis of lead concentration by Atomic Absorption Spectroscopy. The amount of lead accumulated in muscle of experimental fish increased steadily with the period of exposure. The lead accumulated in fish muscle was 29.60±6.62 μg/g at 96 hours of exposure and accumulated up to 72.48±14.18 μg/g in 192 hours of exposure period at the highest concentration. Significant relationship between accumulation and exposure period as well as exposed concentration (p < 0.05) at the significance level of 95 % was recorded. The present study indicated that the fishes living in mudflats of brackish water bodies receiving industrial as well as anthropogenic waste water containing an assortment of heavy metals can accumulate them in considerable concentrations.

“…This decline may be related to the negative impact of Pb toxicity on the various metabolic processes. According to Bengani et al (2015), Pb is a toxic element that impairs biological functions. Ikeogu et al (2016) hypothesized that fish exposed to Pb toxicity experienced slow growth and high mortality rates.…”

“…The relationship between lead concentrations in the water and sediment can provide information about potential sources and transport mechanisms of lead in the study area. However, the absorption and accumulation of lead in fish can be influenced by various factors, such as species, feeding habits, and exposure routes [ 70 ], with the food pathway being more significant in some cases [ 71 , 72 ]. For factors such as transfer and bioaccumulation, elements like Zn and Cu had the highest proportions and interactions with rainbow trout in the study area.…”

“…The reduction in growth may also be attributed to the effect of the heavy metal on enzyme activities and metabolic processes. Bengani et al, (2015) reported that Pb is highly toxic, impairing the biological functions of aquatic animals. Rani and Gupta (2015) reported that water pollution with heavy metals affects various physiological processes in fish including poor food utilization and reduced fish metabolic rate.…”
