Gadani shipbreaking area, located on the coastline of Pakistan, is an important fish production area. In this study, levels of four metals (Ni, Pb, Cd, and Mn) in 148 muscle and gill samples of seven fish species (Small-scale terapon, Torpedo scade, Sicklefish, Saddle grunt, Gold silk seabream, Indian mackerel, Spotted sickle fish) and seawater samples, taken from 9 sampling sites in the shipbreaking area, were determined. In addition, multiple approaches were used to assess human health risks from fish consumption. Trace metal concentration in seawater ranged from 0.05 to 1.96 mg/L in shipbreaking vicinity and 0.03 to 0.97 mg/L in the reference site (Miani Hor). However, metal accumulations in fish species ranged from 1.33 to 5.26 μg/g. Among trace metals, the level of Pb in all fish species was highest, followed by Ni, Mn, and Cd. The bioaccumulation factors (BAFs) for both gills and muscles displayed the order: Mn > Cd > Ni > Pb. Estimated daily intake (EDI) values were below the tolerable daily intake (TDI). Based on target hazard quotient (THQ), the investigated fish species were safe regarding Pb and Mn (THQ < 1), while they may cause potential risk regarding Cd and Ni (THQ > 1). After comparison with maximum permissible limits, heavy metal concentration in the edible muscle tissues of all the analyzed fish species from the Gadani coast were found safe for human consumption.

Consuming contaminated seafood can be potentially harmful for human health, especially for coastal communities. For this reason, a health risk assessment is very important to determine the safe limit for consuming seafood. Several stages in this assessment are; (i) direct comparison with the standard/maximum limit of heavy metal concentration determined by each country or international organization, (ii) determination of the maximum amount of seafood that can be consumed by adults per week, (iii) determination of the Estimated Daily Intake (EDI), and (iv) determination of the Target Hazard Quotient (THQ) of each metal and the Total Hazard Index (HI) for the combined metals.

Abstract: Introduction : Heavy metals are known to cause deleterious effects on human health through food chain. Aims: The study is aimed at assessing heavy metal concentrations in the tissues of four highly consumed fish species and to evaluate the potential health risks associated with their consumption. Materials and Methods: The concentrations of Cu, Cd and Pb were analyzed in the tissues of Titus (Scomber Japonicus), Croaker (Pseudolithus Elongatus), Scumbia (Ilisha Africana) and Shrimps (Pipeus Notialis) by atomic absorption spectrophotometry (AAS) after digestion of the samples. Results: The results showed that Cd was not detected in the tissues of all fish species. There were variations among Cu and Pb concentrations in the tissues of the fish species. Cu had the highest concentrations (1.00 µg/g) in the tissues of croaker and shrimps respectively while Pb had the lowest concentrations (0.25 µg/g) in the tissues of Scumbia . The levels of all metals in the present study were lower than the limits permitted by Food and Agriculture Organization of the United Nations/World Health Organization (FAO/WHO), European Community Regulation (EU) and European Commission (EC). Assessment of noncarcinogenic health hazard using Target hazard quotient (THQ) and hazard index (HI) indicated no concern from consumption of these fish species. The estimated daily intake (EDI) of the studied metals through fish consumption was below the permissible tolerable daily intake. Conclusion: It can be concluded that there is no potential human health risk from consumption of the selected fish species. Keywords: Heavy metals, Hazard index, Target hazard quotient.

In this study, heavy metal concentrations including cadmium, lead, zinc, copper and arsenic concentrations were determined in five fish species (Capoeta sieboldii, Capoeta tinca, Scardinius erythrophthalmus, Squalius pursakensis and Barbus escherichii) obtained from the Sakarya River. The metal concentrations of fish supplied in four different seasons (winter, spring, summer and autumn) were determined by using atomic absorption spectrophotometry. Although the metal concentrations showed seasonal variations in some fish species and also varied with respect to particular fish species, the concentrations of these metals were found to be within the permissible limits. In addition, it was concluded that the concentration of metal contamination in the evaluated fish species would not pose a risk for human consuming fish species obtained from Sakarya River by considering estimated daily intake (EDI), target hazard quotient (THQ), hazard index (HI), and target cancer risk (TCR) values.

Abstract Potential toxic metals (PTEs) accumulation in soil and water is one of the major sources of food crop contamination. PTEs remediation from soil can be enhanced by addition of organic matter to the growing media. An experiment was carried out to investigate the effect of different organic amendments on the accumulation of PTEs in pea plant grown on mine degraded soils. Mining soils from chromite mine (CM), soap stone mine (SSM), manganese mine (MM) and quartz mine (QM) were mixed with vermicompost (VC), leaf mould (LC) and spent mushroom compost (SMC) along with garden soil at 1:1:1 ratio. Various growth and yield related attributes of pea plant as well as PTEs concentrations in soil and plants were studied. The highest Cd (2.62 mg kg−1) and Cr (13.6 mg kg−1) concentration was reported in CM soil, while Pb (23.3 mg kg−1) and Mn (59.2 mg kg−1) concentration in SSM and MM soil, respectively. Mining soils significantly reduced the plant growth and yield, while organic amendments reduced the PTEs availability and increased pea plant growth. Comparing the various organic fertilizers used, it was observed that VC efficiently reduced Cd, Cr, Pb and Mn uptake by pea plant, subsequently, improved pea plant growth. In order to assess the effects of various amendments on PTEs health risk reduction various risk indices including, plant trafser factor, average daily intake, health risk, target hazard quotient and target cancer risk were also calculated and the results revealed that application of compost particularly VC significantly reduced the dietary intake and health risks of PTEs.

Fish and marine mammal consumption are an important pathway for human exposure to mercury. The low mercury content in shellfish poses a low mercury health risk to people who consume shellfish. The objectives of this study are to detect mercury concentrations in different species of shellfish and to calculate the mercury health risk from shellfish consumption among traditional residents near northern Jiaozhou Bay. A total of 356 shellfish samples, which comprised 7 species from 5 different places in northern Jiaozhou Bay, were collected from April to June in 2012. The average mercury content in the collected shellfish ranged from 0.024 mg·kg−1to 0.452 mg·kg−1. A total of 44 shellfish samples (12.36%) had mercury levels exceeding the national pollution-free aquatic products limit (0.3 mg·kg−1). Generally, the viscus had the highest mercury content among all parts of the shellfish. A positive correlation between mercury content and total weight/edible part weight was found in most species of the collected shellfish. The results showed that shellfish consumption resulted in the lower risk of mercury exposure to residents based on the calculation of daily intake (DI) and target hazard quotient (THQ).

Heavy metals and some pathogenic bacteria tend to contaminate food substances commonly consumed and this pose as health risks to the populace. The study was therefore conducted to assess the level of metal and bacteria contamination of meat barbecue (SUYA) commonly consumed in Anambra State, Nigeria. Thirty six sample were evenly collected from the sensational Zones and analyzed using Atomic Absorption Spectrophotometer. Metal values obtained range as follows: Cadmium(4.17-7.93mg/kg), Lead(0.24-3.39mg/kg),Zinc(2.6-28.3mg/kg) and Arsenic(0.19-2.3mg/kg). Samples from Anambra North had the highest Zinc, Lead, and Arsenic levels 14.02, 0.94, and 0.96mg/kg rewspectively, while Anambra South recorded the highest cadmium level 6.16mg/kg. The Estimated daily intake(EDI) of Cadmium alone was found to be greater than the recommended value in the 3 senatorial zones. Again only Cadmium had a target hazard quotient(THQ) of greater than one in all the senatorial zones. All the zones had hazard index (HI) greater than one. North(5.95+00). South,(8.1E+00) and Central(4.8+00). Cancer risk for cadmium recorded in all the zones were above accepted limits. While for Arsenic the North zone recorded levels above acceptable limits. The following bacteria species were isolated from analyze soya samples. Staphyloccocus cereus, Bacillus aureus, Salmonella species, Pseudomonas aeruginosa, Klebsiella pneumonia,however bacillus cereus was most commonly isolated and Pseudomonas aeruginosa least commonly isolated. The results indicated an appreciable level of contamination and a possible public health risk.
