Assessment of health risks associated with heavy metal contamination in selected fish and crustacean species from Temsah Lake, Suez Canal

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Marine pollution caused by heavy metals has emerged as a significant environmental concern, garnering increased attention in recent years. The accumulation of the tissues marine organisms poses substantial threats to both ecosystems and human populations that rely on seafood primary food source. Fish crustaceans are effective biomonitors for assessing metal contamination aquatic environments. In this study, we determined concentrations several metals, including cadmium (Cd), lead (Pb), nickel (Ni), mercury (Hg), tin (Sn), four fish species (Mugil cephalus, Mugil capito, L. aurata, Morone labrax) five crustacean (S. rivulatus, Cerastoderma glaucum, Paratapes undulatus, R. decussatus, Callinectes sapidus, Metapenaeus Stebbingi) from Temsah Lake during winter summer seasons. To evaluate potential ecological health risks associated with consuming these species, calculated index (MPI), weekly intake (EWI), target hazard quotient (THQ), carcinogenic risk (CR) values. results revealed noticeable increase levels compared studied samples. Moreover, concentration muscles generally exceeded those liver gills. MPI values indicated labrax exhibited highest winter, while aurata showed summer. cephalus demonstrated lowest EWI were found be lower than corresponding tolerable (TWI) Additionally, under average exposure conditions, THQ HI data below one most study area. CR investigated acceptable levels. Therefore, suggests within lake does not present any hazards consumers.

Source apportionment, ecological and health risk assessment of potentially toxic elements in water, sediment and blackchin tilapia {Sarotherodon melanotheron (Rüppell 1852)} from Lagos and Ologe Lagoons, Lagos State, Nigeria

Journal of Trace Elements and Minerals, Journal Year: 2024, Volume and Issue: 9, P. 100173 - 100173

Published: June 7, 2024

Lagos and Ologe Lagoons are parts of the Lagoon Complex, which provide fish as an animal protein source to locals. However, these species have a high propensity accumulate pollutants including Potentially Toxic Elements (PTEs) from their environment. This potentially constitutes health risk consumers. Therefore, this study investigated concentrations some PTEs (As, Cd, Cr, Cu, Fe, Pb, Ni, Zn) in water, sediment, (Sarotherodon melanotheron) Lagoons, ecological risks associated with consumption well likely sources PTEs. Water, (S. samples were collected monthly for ten months (June 2022 - March 2023) three sites: Badore Baiyeku Lagoon. The concentration was determined environmental matrices {water, organs (gill, muscle, liver)}. range values method detection limits (MDL), (LOD), quantitation (LOQ), recovery rates 0.01 – 0.025 mg kg−1, 0.00002 0.002 L−1, 0.0001 0.0067 L−1 97.19±2.45 99.85±1.16% respectively.
