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.

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.

Crustaceans are known for their trace element bioaccumulation abilities. Muscle tissues of lagoon crab, marine crab, pink shrimp and mantis shrimp marketed for consumption in Nigeria were analyzed for Mn, Fe, Cu, Zn, Hg and Cr levels using standard methods. Muscle levels in mg kg-1 of Mn (0.03±0.00 in lagoon crab), Fe (0.072±0.01 in mantis shrimp), Cu (0.344±0.01 in lagoon crab) and Zn (0.073±0.00 in mantis shrimp) were significantly different (p<0.05) from their corresponding values in other examined crustaceans. The mean values of Cr and Hg were not significantly different across samples. The estimated daily intake of trace element (mg person-1day-1) revealed that Hg (0.000001) in marine crab contributed the lowest daily intake while Zn (0.000226) in lagoon crab contributed the highest daily intake. Total hazard quotient (THQ) values for the trace elements followed descending order of Hg > Cu > Zn > Fe > Mn > Cr. Lagoon crab showed the highest total hazard index among the organisms with 44.80 %, while the least was observed in mantis shrimp with 13.30 %. It is concluded that, as far as human health is concerned, the mean elemental levels in the muscle tissues of the organisms examined pose no danger (THQ < 1).

In the present study, a risk assessment of pesticides, phthalates and heavy metals in strawberries (n = 335) in recent years was conducted by determining the out estimate dietary intake (EDI), target hazard quotient (THQ) and hazard index (HI) . 128 Pesticides, 18 phthalates and 3 heavy metals were determined in this determination. 51 pesticide residues were detected in the strawberry samples, and 97.91% samples had levels of at least one of the 51 pesticides above the LOD (limit of detection). 2.39% of samples had pesticides higher than the Chinese MRL. Multiple pesticides residues were detected in most samples. Bis-2-ethylhexyl phthalate (DEHP), diisobutyl phthalate (DIBP) and dibutyl phthalate (DBP) were detected in the strawberry samples with high frequency of detection. Their detectable rates were 100, 100 and 89.9%, respectively. Most of the samples were detected lead (Pb), cadmium (Cd) and nickel (Ni) with the detectable rates 75.76, 92.93 and 92.93%, respectively. Estimated daily intake of analyzed pesticide, phthalate and heavy metal residues appear to be relatively low compared to the ADI. The average THQs and HI were less than one. That means the customers who are exposed to the average contaminants levels may not pose significant health risk. Our results show that the strawberries may be polluted by many kinds of contaminants. Therefore, monitoring of pesticides, phthalates and heavy metal residues in strawberries should be increasingly developed in order to fully protect the health of the consumer.

The objective of this study was to evaluate the chronic-toxic risks posed by individual metals via food supplements consumption by computing the hazard quotient (HQ), considering the average daily metal intake ADD (mg/kg�day), daily intake reference dose RfD (mg/kg� day) suggested by the European Food Safety Authority (EFSA), heavy metal concentration C in food supplements (mg/kg), food supplements rate IR (kg/person�day), and the average body weight BW (kg). For this study we took into consideration that the food supplements analyzed are consumed daily at maximum dose. Samples were digested with concentrated nitric and hydrochloric acid and analysed for their inorganic elemental compositions by ICP/MS. The hazard index (HI) was used to estimate total chronic-toxic risks of multiple metals on the assumption of dose additivity. Cd hazard index is over one and it can be considered a great issue due to its chemical toxicology. The Cd hazard index is much greater in the case of animal and mineral food supplements than vegetal supplements. In the case of the other heavy metals analyzed (Cr, Cu, Zn, As, Hg and Pb) the hazard index is very low so their toxicological potential is negligible.

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.

The residue level, dissipation behavior, and dietary intake risk of chlorpyrifos-methyl, dimethoate, permethrin, iprodione, metalaxyl, and propargite in parsley (Petroselinum crispum) were investigated under field conditions. Extraction and determination of pesticide residues were carried out by a quick, easy, cheap, effective, rugged, and safe (QuEChERS) method and a gas chromatography/tandem mass spectrometry (GC/MS/MS) system, respec-tively. Dissipation of chlorpyrifos-methyl, dimethoate, permethrin, iprodione, metalaxyl, and propargite in pars-ley followed the first-order kinetics with a half-life (t1/2) of 3.33, 3.30, 2.94, 3.52, 4.10, and 3.38 days, respectively. Based on the dissipation pattern and the maximum residue limits (MRL), preharvest intervals (PHI) of 25, 13, 18, 24, 1, and 16 days are suggested for chlorpyrifos-methyl, dimethoate, permethrin, iprodione, metalaxyl, and propargite in parsley, respectively. The estimated daily intake (EDI) of pesticides ranged from 7.37E-05 (dimeth-oate) to 8.00E-04 (metalaxyl) mg/kg. The chronic risk assessment showed that the hazard quotient (HQ) was <1 and Hazard Index (HI, indicating the cumulative exposure to pesticide residues) was <100%, demonstrating that an intake of pesticide residues from parsley was safe for humans.

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.

Marine Environmental

Marine environmental pollution is a longstanding global problem and has a particular impact on the Bay of Bengal. Effluent from different sources directly enters rivers of the region and eventually flows into the Bay of Bengal. This effluent may contain radioactive materials and trace metals and pose a serious threat to the coastal environment, in addition to aquatic ecosystems. Using gamma spectrometry and atomic absorption spectrometry, a comprehensive study was carried out on the radioactivity (226Ra, 232Th, 40K, and 137Cs) and trace metal (Cd, Pb, Zn, Cu, Ni, Fe, Mn, and Cr) concentrations, respectively, in fish and crustacean species collected from the coastal belt of the Bay of Bengal (Chattogram, Bangladesh). The analysis showed a noticeable increment in the levels of different radioactive pollutants in the marine samples, although the consumption of the studied fish and crustacean species should be considered safe for human health. Anthropogenic radionuclide (137Cs) was not detected in any sample. Furthermore, the metal concentrations of a small number of trace elements (Pb, Cd, Cr) were found to be higher in most of the samples, which indicates aquatic fauna are subject to pollution. The estimated daily intake (EDI), target hazard quotient (THQ), hazard index (HI), and target cancer risk (TR) were calculated and compared with the permissible safety limits. It was found that consuming the seafood from the Bay of Bengal may cause adverse health impacts if consumption and/or means of pollution are not controlled.

Aim: The present study was aimed to determine the concentration of heavy metals (Pb, Cr, Mn, Cu and Cd) in waterleaf (Talinum triangulare), lettuce (Lectuca sativa) and spinach (Amaranthus hybridus) from three farmlands. Study Design and Place of Study: The research was carried out at Kwadon in Yamaltu Deba local Government of Gombe State, Kwadon is located between latitude 10.270ºN and longitude 11.28ºE. Methodology: The heavy metal concentration in the vegetables was determined by atomic absorption spectrophotometry. Results: The result showed that the heavy metals concentration in the vegetables across the farms ranges from 2.0–34.4 mg/kg for Mn, 0.025 mg/kg for Cd, 1.7–23.7 mg/kg for Cr, 0.2–1.0% for Cu. The concentration of Mn and Cr are higher than the permissible limit of FAO/WHO in vegetables. To assess the health risk associated with the heavy metals concentration from these vegetables, daily intake of metal (DIM), health risk index (HRI), and target hazard quotient (THQ) were calculated. The daily intake of metals in vegetable species for Mn (0.17–2.81), Cd (2.1), Cu (0.02–0.08), Cr (0.1–2.0) are significantly higher than the recommended daily intake of metals and the upper tolerable daily levels. Conclusion: This result reflects the risk associated with exposure for the period of life expectancy considered and the inhabitant, are highly exposed to the health risk associated with these metals.
