“…As the result showed, the HQ dermal contact of Cr determined for more than 63% of HI dermal contact for children. This was consistent with the previous studies; they reported that dermal contact with Cr contributed to higher non-carcinogenic risk compared to other exposure routes [17, 40].…”

Background Arsenic and heavy metals are the main cause of water pollution and impact human health worldwide. Therefore, this study aims to assess the probable health risk (non-carcinogenic and carcinogenic risk) for adults and children that are exposed to arsenic and toxic heavy metals (Pb, Ni, Cr, and Hg) through ingestion and dermal contact with drinking water. Method In this study, chemical analysis and testing were conducted on 140 water samples taken from treated drinking water in Mashhad, Iran. The health risk assessments were evaluated using hazard quotient (HQ), hazard index (HI), and lifetime cancer risk (CR). Results The results of the HQ values of arsenic and heavy metals for combined pathways were below the safety level (HQ < 1) for adults, while the HI for children were higher than the safety limit in some stations. Likewise, Cr showed the highest average contribution of HItotal elements (55 to 71.2%) for adult and children population. The average values of total carcinogenic risk (TCR) through exposure to drinking water for children and adults were 1.33 × 10−4 and 7.38 × 10−5, respectively. Conclusion Overall, the CRtotal through exposure to drinking water for children and adults was borderline or higher than the safety level of US EPA risk, suggesting the probability of carcinogenic risk for the children and adults to the carcinogenic elements via ingestion and dermal routes. Therefore, appropriate purification improvement programs and control measures should be implemented to protect the health of the residents in this metropolitan city.

“…The mean Ni content in chicken in the present study (0.035–0.940 mg/kg) was lower than the values reported in Dareta, Northern Nigeria (1.012 mg/kg) 25.

Background.Bangladesh is a densely populated country with a high demand for non-vegetable protein. Poultry meat is an important source of protein due to its affordability. Trace metals are persistent in the environment and are subject to bioaccumulation in the food chain. Contaminated poultry feed can pose a risk to human health as it biomagnifies and bioconcentrates toxic metals up the food chain, which can enter the human body and cause adverse and toxic health effects.Objectives.The aim of the current study was to assess the concentration and distribution of metals such as arsenic (As), cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu) and nickel (Ni) in different types and parts of poultry in markets in Dhaka, Bangladesh.Methods.A total of 15 chickens were collected from five commercial markets of Dhaka city. Three types of poultry were selected, broiler, layer and cock. Altogether, 45 chicken samples were analyzed for toxic metals concentrations using inductively coupled plasma optical emission spectroscopy.Results.The concentrations of As, Cd, Co, Cr, Cu and Ni obtained in the broiler, layer and cock chickens were 0.728, 0.232, 0.392; 0.595, 0.245, 0.271; 0.058, 0.016, 0.096; 5.275, 1.562, 22.180; 3.571, 2.269, 4.241, and 0.332, 0.211, 0.433 mg/kg (wet weight), respectively. The results indicate that the concentrations of As, Cr, and Cu in the analyzed samples exceeded the maximum permissible levels, whereas the concentrations of Cd and Ni were within acceptable limits. Metal concentrations decreased in the order of Cr > Cu > As > Cd > Ni > Co. The target hazard quotient and cancer risk values were estimated for each metal due to consumption of the different types of chicken.Conclusions.The estimated metal concentrations of As, Cr and Cu were higher than the permissible levels of international standards, indicating a health risk. Groundwater in many parts of the country is contaminated with As and is a probable source of As contamination in poultry. High concentrations of Cr and Cu in chicken may be caused by contaminated poultry feed. In the present study, layer chickens were comparatively less contaminated with metals than other types of chicken. The estimated target hazard quotient and cancer risk values of the analyzed chicken samples were lower than acceptable limits for all individual trace metals in the three types of chicken, indicating no non-carcinogenic and cancer health risk from ingestion of a single trace metal through consumption of these chickens.Ethical Approval.This study was approved by the Academic Committee of the Institute of Leather Engineering and Technology, University of Dhaka, Bangladesh.Competing Interests.The authors declare no competing financial interests.

“…Similarly, higher levels of Cu, Zn, Pb, and Cd were found in poultry meat retailed in Sharkia Governorate, Egypt (El-Bayomi et al, 2019). Also, substantially higher ranges of Pb, Cd, Ni, Cu and Cr in chicken meat were reported from Bangladesh (Mottalib et al, 2018), China (Wang et al, 2018), Algeria, (Benouadah et al, 2015).…”

Chicken meat is classed among one of the major sources of animal proteins and still enjoys global acceptance to date without recourse to their heavy metal residues. Hence, this study investigated the heavy metal residues in raw chicken meat and the associated health risk via consumption within major markets in southern Nigeria. A total of 240 raw chicken meat samples (muscle tissues) were purchased randomly from Warri, Akure, Ado-Ekiti and Benin City markets. After ashing, digestion and heavy metals analysis for Pb, Cr, Cd, Mn, Ni, Zn and Cu using standard atomic adsorption spectrophotometer, the target hazard quotient (THQ), health risk index (HI) and daily intake index (non-carcinogenic risk) and incremental cancer risk in children and adults were determined. The mean heavy metals ranged from 0.001 ± 0.001 mg/kg (Cr) to 2.094 ± 0.001 mg/kg (Zn) and varied significantly (P<0.05) with Warri samples (58.9 %) yielding the highest level, followed by Benin City (26.8 %), Ado-Ekiti (10.2 %) and Akure (4.2 %) samples. The non-carcinogenic risks (HR/HI) were substantially low for the metals studied in all the locations except for Cd, which could pose serious health risk among children in Warri location. However, the incremental cancer risk ranged from 10-4 to 10-3 in all the locations, suggesting at least a cancer case per 1,000 exposed people (both in children and adults). Considering the impending public health risks, critical hazards points of heavy metals contaminations along meat production chains should be properly identified to drastically reduce their potential risks to exposed consumers.
