“…THQ values similar to this study were obtained in a research analysing the arsenic concentration in fish bought from markets in Bangladesh (Saha & Zaman 2013). Moreover, the inorganic arsenic THQ value from consumption of marine cultured fish in China (0.05) was found to be the critical level (Onsanit et al, 2010).…”

The aim of the present study was to determine the amount of arsenic in the muscular tissues of wild sea breams, sea breams cultured in soil ponds and sea breams cultured in off-shore marine cage systems in the Aegean Region of Turkey. Then an estimated daily intake (EDI) and target hazard quotient (THQ) based risk assessment by sea bream consumption in terms of arsenic was performed for both children and adults. The arsenic concentrations in the muscular tissues of fish were detected by inductively coupled plasma-mass spectrometry method after digestion by microwave wet burning. According to the results obtained, the highest average arsenic concentration was found in sea bream cultured in soil pond while the lowest was determined in off shore marine cultured sea bream. The arsenic concentrations determined in all fish groups were found out to be below 1 mg.kg -1 wet weight which is the international legal limit. Also the EDI values determined for children and adults were lower than 0.30 µg/kg/day, the oral reference doses (RfDo) value for arsenic and THQ value was found out to be lower than the value assessed as potentially carcinogenic. Summarising, the results of this study do not underline any potential risk in term of arsenic deriving from consumption of sea bream cultured and caught in Aegean Sea.

This review paper highlighted possible ways of heavy metal contamination of food chain in a developing country like Bangladesh as it is considered an emerging threat for food safety. The review paper was prepared over a period of six months by searching and collecting data of various studies done in Bangladesh from original articles of many national and international journals. Also, data were taken from related review articles of many journals and websites. The review showed that arsenic, cadmium, chromium and lead are the four major threats for heavy metal contamination of food chain in Bangladesh. Pollution of surface water, agricultural soil by unscientific industrial effluent disposal and application of chemical fertilizers, pesticides are the major ways of heavy metal contamination. Consumption of these heavy metals with food above safe limit causes various organ dysfunctions including cancer.

Health risks due to consumption of pesticides in ready-to-eat vegetables (salads) in Kumasi, Ghana

Background: Pesticide residue levels were determined in ready-to-eat vegetables collected from 16 sites along the food chain; which is, farms, markets, cafeterias and street food vending sites in Kumasi, Ghana. The aim of the study was to determine the concentrations of pesticides residues in two ready-to-eat vegetables and assess the health risks due to consumption of these contaminated vegetables. Methods: Pesticide residues in ready-to-eat vegetables or salads were extracted by means of the QuEChERS method. Synthetic pyrethroid and organophosphorus pesticides residues in samples were determined using Gas Chromatography with Electron Capture Detector and Pulsed Flame Photometric Detector respectively. Consumption data of ready-to-eat vegetables were obtained from a questionnaire-based dietary survey in the study area. The hazard index and the relative potency factor (RPFs) approaches were used to assess the health risk from chronic cumulative dietary exposure to pesticides. Results: There were six synthetic pyrethroid residues detected in the ready-to-eat samples at varying concentrations. They were bifenthrin, permethrin, cypermethrin, deltamethrin, lambda-cyhalothrin and fenvalerate. Also, two organophosphates were detected in the samples; which were chlorpyrifos and diazinon. Lambda-cyhalothrin residues was present in all the samples in the study, with the mean concentration of 4.5 × 10 −2 mgkg −1 . The mean concentration of diazinon in all the samples (0.040 mgkg −1 ) exceeded the EU MRLs (0.01 mgkg −1 ), chlopyrifos exceeded its MRL in one sample from the street food vending site and cafeteria each. Deltamethrin, Fenvalerate and Permethrin exceeded their respective MRL in samples from Asafo (Street food vending sites) and Adum (Cafeteria) and KNUST (Farm) respectively. However, the health index of all pesticides residues detected were below the permissible limit. The cumulative intake from the RPF approach for the pesticides were relatively lower than the ADI of the index chemicals. Conclusion: The concentrations of chlorpyrifos, deltamethrin, fenvalerate, diazinon and permethrin exceeded their respective EU MRLs in some ready-to-eat vegetable samples in the study. The health index and comparison of cumulative intake from RPF with ADI of the index chemicals suggest that pesticide residues in ready-to-eat vegetables could not be considered a major public health problem.
