HighlightHeavy metals (Cu, Zn, Pb, and Cd) in the seawater, sediment, soft part of marine mussels were analyzedBioaccumulation Factor (BAF), Estimated Daily Intake Target Hazard Quotient (THQ) calculatedHeavy sediment found varying concentrationsHealth risk assessment indexes showed low values which means insignificant health hazardAbstractMarine are known as one biological indicators heavy pol...

Rare information on the seafood safety and coastal water-food-energy nexus sustainability in terms of is available. This study investigated distribution heavy metals 3 kinds (bivalve molluscs, fish, crustaceans) collected from areas along 18,000 km coastline China. Risk assessment source apportionment metals, metal pollution were also performed. The results showed that total concentrations 8 (C...

Dietary uptake is well known as the predominant pathway of heavy metal bioaccumulation in organisms. Our study used a typical tropical reservoir and fish modeling system to test hypothesis that feeding habits living habitats significantly affect fish. Specifically, Cr, Mn, Fe, Ni, Cu, Zn, Cd, Pb concentrations water, sediment, fish, δ13C δ15N 13 species were detected Songtao Reservoir Hainan Pr...

Background: Oily fish and their extracted oils may be a source of polychlorinated biphenyls (PCBs) which can induce toxic effects on the consumers. The main aim of this survey was estimation of PCBs intake through fish oil-derived dietary supplements and prescription drugs in the Japanese population. Methods: PCBs levels were determined in 20 fish oil-derived dietary supplements and 6 oil-deri...

The concentrations of total mercury, polychlorinated biphenyls (PCBs), and organochlorine pesticides (SigmaDDT, dieldrin, hexachlorobenzene [HCB], and SigmaHCH) were determined in 61 whale meat products (bacon, blubber, red meat, liver, intestine, and tongue) purchased from retail outlets across Japan. Mean (range) concentrations of contaminants in all samples were: total mercury 4.17 (0.01-204...

Human health risks associated with the consumption of three shellfish (<i>Penaeus monodon, Crassostrea rhizophorae</i>, and <i>Tympanostomus fuscatus</i>) harvested from Buguma, Krakrama, Bonny Rivers in Niger Delta region were evaluated this study. The bioaccumulation potential toxic elements (PTEs) [Arsenic (As), Cadmium (Cd), Chromium (Cr), Lead (Pb), Nickel (Ni)] was...

It is recognised as a nutritionally essential element with daily adequate intake (AI) of 25 μg for women and 35 μg for men and with serum levels in healthy humans from developed countries of 2.3 40.3 nmol/l. The US Environmental Protection Agency (EPA) has replaced acceptable daily intake with calculated reference dose (RfD). The RfD is calculated from the ‘no observed adverse effect level’ fro...

conclusions in all of the investigated imported rice samples, the level of afb1 and total afs were found to be lower than the iranian mtl, and no health risk for consumers were detected at these levels of contamination. results the results showed that the highest concentration of afb1 and total afs in the rice samples were 2.3500 and 2.7040 ng/g, respectively. the different mean concentration o...

materials and methods a total of 40 different bread types such as barbari, sangak, lavash, and baguette produced in 124 bakery shops in rasht city were analyzed for some heavy metals (as, cd, pb, cr, ni, and co) by inductive coupled plasma (icp) instrument (icp-qes). results the mean content of the as, cd, and pb in different breads were respectively as follows: barbari, 0, 0.73, and 0.07; sang...
