Abstract:
Aquatic environment of Jakarta Bay have already been highlighted due to its heavy metals contamination which may lead into food safety concern of fisheries products derived from this region. This research aimed to investigate bioaccumulation level of heavy metals (Pb, Cd, and As) in fish and mussels from Jakarta Bay, as a human risk assessment of seafood consumption. Samples of mussels and fish were taken from Penjaringan, Tarumanegara, Cilincing, and Tanjung Pasir district. Bioaccumulation of heavy metals was analyzed by Inductively Coupled Plasma -Mass Spectrometry technique. Results of the

Abstract:
The bioaccumulation of trace elements and heavy metals in aquatic organisms is a critical environmental concern due to its potential impact on ecosystem health and human safety. This study investigated the level of trace elements and heavy metals bioaccumulation in Labeo rohita and Mystus seenghala from the River Jhelum in the district Khushab, Punjab, Pakistan. The concentration of calcium, magnesium, iron, nickel, copper, arsenic, cadmium, zinc, chromium, manganese, cobalt, and lead in the gills, liver, and muscle tissues of these fish was measured using inductively coupled plasma-mass spect

Abstract:
This study was conducted to assess the health risk of heavy metals from some fruits and vegetables sold in the Dutse Ultra-modern market, Jigawa State. Two fruits (watermelon and orange) and two vegetables (okra and spinach) were selected randomly from two vendors for two consecutive periods within one week. The samples were transported to the laboratory for acid digestion. Atomic Absorption Spectrophotometer (AAS) was used for the determination of heavy metal (Cd, Pb, Zn, Fe, Mg, Cr and Ni) concentration in the various samples.

Abstract:
Dieldrin is legacy organochlorine insecticide, which was listed in the Stockholm Convention because of its persistence, bioaccumulation and toxicity. However, it is still present in the environment and in organisms two decades after its ban. The current criteria used for risk assessment in China are based on acute toxicity data in water columns without considering the bioavailability and bioaccumulation, which accordingly lead to the under-protection of aquatic organisms and wildlife. In this study, the water quality criteria (WQC) for dieldrin were derived from a combination of tissue-based t

Abstract:
Field surveys on persistent organic pollutant (POP) bioaccumulation were conducted with oysters, clams and scallops whose consumption amount accounted for large shares in the total consumption of shellfish in Japan. There was no numerical difference in bioaccumulation characteristics between oysters, clams, scallops, Corbicula and Mytilus galloprovincialis. Therefore, it was clear that the bioaccumulation characteristics in oysters, clams and scallops, which are important for food, could be ascertained by using the monitoring results with Corbicula and M. galloprovincialis which are easily sam

Abstract:
Mercury (Hg) is globally recognized as a persistent chemical contaminant that accumulates in marine biota, thus constituting an ecological hazard, as well as a health risk to seafood consumers. Climate change-related stressors may influence the bioaccumulation, detoxification, and toxicity of chemical contaminants, such as Hg. Yet, the potential interactions between environmental stressors and contaminants, as well as their impacts on marine organisms and seafood safety, are still unclear. Hence, the aim of this work was to assess the bioaccumulation of Hg and neuro-oxidative responses on the

The objective of this study was to evaluate the impact of biochar application on the reduction of heavy metal contamination in soils and their bioaccumulation in lettuce. The study was carried out in Bobo-Dioulasso, Burkina Faso. Lettuce was grown in pots containing contaminated soil amended with three different types of biochar at three different doses. At maturity, the lettuce was harvested and the concentration of heavy metals in various organs was determined. The results showed that in terms of bioaccumulation in lettuce, the roots showed the highest accumulation of heavy metals, especiall

Abstract This study investigates trace metal concentrations in water, sediment, and fish from the Epe Lagoon, Nigeria. Sediments showed the highest levels, with iron being the most abundant, followed by zinc, manganese, copper, nickel, chromium, and lead. Significant differences in zinc accumulation factors were observed between Clarias gariepinus and Tilapia mariae. Biosediment accumulation factors (BSAF) for all metals were below one, with copper and iron showing the highest bioaccumulation in both fish species. The estimated daily intake of metals was below reference doses, with the highest

A research project was conducted to investigate the cadmium bioaccumulation in chickens fed. In this direction, cadmium concentration was determined in maize plant parts and in seven tissues of chickens to study the potential human risk of consumption of these chickens by finding out the cadmium target hazard quotient - THQ ([1). In addition, the pollution load index for soil was also determined. The concentration of cadmium in maize and chicken body parts was determined by atomic absorption spectrophotometer.

Abstract:
The study assessed human health risk and accumulation of heavy metals (Cd, Cu, Pb, Ni, Cr and Zn) in periwinkles (Tympanotonus fuscatus) obtained from the Niger Delta region of Nigeria. Samples were collected for six months on a monthly basis. The samples were digested according to the method described by Association of official analytical chemists and analyzed using atomic absorption spectrophotometer (AAS). Temporal variations in metal concentrations were observed with values (mgkg−1) ranging as follows Pb (2.34–6.7), Ni (0.55–2.28), Zn (0.55–11.66), Cr (0.74–3.65), Cu (1.15–3.91) and Cd (0.
