Rainwater is considered a dependable source for domestic purposes within rural areas in Palestine. Harvested rainwater stored in cisterns is used to leverage deficits from municipal water supplies. Harvested rainwater in areas surrounded with industrial and agricultural activities is usually contaminated with heavy and trace metals. To study the effects of human exposure to heavy and trace metals, 74 harvested rainwater samples of rain-fed cisterns were collected from different localities in the Yatta area of Palestine in the months of January and February of 2016. The water samples were analysed for Ca, Mg, Al, Fe, K, Na, Ag, Li, Co, Ba, Bi, Sr, Ga, V, Rb, Mo, Beand Tl elements utilizing ICP-MS (inductively coupled plasma mass spectrometry). The selected trace metals were found within the concentration limits of the acceptable values, in accordance with WHO and Palestinian standards, except for K and Al, which were found above the allowed limits. The potential risks of the selected trace metals on the health of the local residents, as well as the possible sources of such heavy metals, were also studied. The Chronic daily intake (CDI) of each metal and health risk indexes (HRI) were calculated for both adults and children residents. The oral ingestion pathway was studied, including exposure via drinking water. The values for CDI were found in the descending order of: Ca > Mg > Na > K > Sr > Fe > Al > Ba > Li > V > Rb > Ag > Mo > Ga > Co > Bi > TI > Be. The values of HRI were below 1 for most of the selected heavy metals, expect for Li for children, indicating potential health risk. The study also predicted that the local residents have a higher chance of developing cancer in their lifetime, especially children, with respect to the carcinogenic risk (CRing) values for Na, Mg, Al, Ba, K, Ca, Fe and Sr, which were greater than standardized limits (>10−6). The rest of the selected elements were within the acceptable limit in the five different studied locations. Furthermore, univariate, multivariate and statistical analysis depending on one-way ANOVA, inter-metal correlation, cluster analysis (CA) and principal component analysis (PCA) results revealed that geogenic and anthropogenic activities were major sources of drinking water contamination by heavy metals in the Yatta area.

Background. Heavy metals contamination of food is a serious threat. Long term exposure may lead to human health risks. Poultry and eggs are a major source of protein, but if contaminated by heavy metals, have the potential to lead to detrimental effects on human health. Objectives. The objective of this study is to determine chromium concentrations in poultry meat (flesh and liver) and eggs collected from poultry farms in Dhaka, Bangladesh, to calculate the daily intake of chromium from the consumption of poultry meat and eggs for adults, and to evaluate their potential health risk by calculating the target hazard quotients (THQ). Methods. All samples of poultry feed, meat (flesh and liver) and eggs were analyzed by a graphite furnace atomic absorption spectrometer (AAS) (GFA- EX- 7i Shimadju, Japan). Results. Chromium concentrations were recorded in the range of not detected (ND) to 1.3926±0.0010 mg kg−1 and 0.0678±0.0001 mg kg−1 to 1.3764±0.0009 mg kg−1 in the liver of broiler and layer chickens, respectively. Chromium concentrations were determined in the range of 0.069±1.0004 mgkg−1 to 2.0746±0.0021 mg kg−1 and 0.0362±0.0002 mg kg−1 to 1.2752±0.0014 mg kg−1 in the flesh of broiler and layer chicken, respectively. The mean concentration of chromium in eggs was 0.2174−1.08 mg kg.−1 The highest concentration of chromium 2.4196±0.0019 mg kg−1 was found in egg yolk. Target hazard quotients values in all poultry flesh, liver and eggs samples were less than one, indicating no potential health risks to consumers. Conclusions. The estimated daily intake values of chromium were below the threshold limit. Thus, our results indicate that no adverse health effects are expected as a resultof ingestion of chicken fed with tannery waste. Competing Interests.

Background. Most traditional medicines were prepared from plant origins. These plants could be contaminated by heavy metals, pesticides, and/or toxins. Therefore, the aim of the present study was to determine the level of heavy metals such as lead (Pb), cadmium (Cd), chromium (Cr), and copper (Cu) in frequently used traditional herbal preparations sold in Northeast Ethiopia and to estimate their health risks associated with their daily intake. Methods. A total of 6 traditional herbal preparations were randomly collected from local herbal shops of Dessie and Kombolcha town, Northeast Ethiopia. The samples were prepared for analysis by wet digestion method using nitric acid and hydrochloric acid treatment. The accuracy of the method was analyzed by the spike recovery test. Determination of Pb, Cd, Cr, and Cu by microwave plasma atomic emission spectroscopy was made in herbal preparations traditionally used in Dessie and Kombolcha town, Northeast Ethiopia. By calculating estimated daily intake (EDI), hazard quotients (HQ), and Hazard Index (HI) of metals, the health risk associated with the consumption of the analyzed herbal preparations was also evaluated. Results. The levels of heavy metals were in the range of 3.0–3.92 mg/kg for Pb, 5.35–10.7 mg/kg for Cr, and 0.815–12.3 mg/kg for Cu. However, cadmium was not detected in any of the traditional herbal preparations. This study revealed that the level of Pb and Cu in all analyzed samples was within the WHO maximum permissible limit of 10 mg/kg and 40 mg/kg, respectively. The level of Cr in all traditional herbal preparations was beyond the WHO maximum permissible limit (2 mg/kg). From the health point of view, the HQ value of Cr for KD-03 and KD-04 is greater than 1, suggesting potential health risk. Furthermore, the HI value had revealed that the consumption of KD-02, KD-03, and KD-04 samples had the potential of posing health risks to consumers over long-term consumption of herbal preparations. Conclusion. This study showed that most of the metal concentration levels in the herbal products were within the WHO maximum permissible limits. However, all samples had Cr levels above the WHO maximum permissible limit. Based on the results of this study, there would be a noncarcinogenic health risk to the consumer associated with the consumption of some herbal preparations marketed in Northeast Ethiopia.

This study was carried out to establish health impacts of some trace elements (Al, As, Ba, Cr, Cu, Fe, Mn, Ni, Pb and Zn) in Asa-river, using Inductively Coupled Plasma-Mass Spectrometer technique for the chemical analysis. Laboratory results show that Al, Fe and Mn average concentrations are higher than prescribed limits unlike others. The Contamination Indexes reveal that the elements are heavily loaded in the water. The exposure dose in both adults and children ranges from 0.021 in As to 181 in Fe (in adults) and from 0.068 in As to 576 in Fe (in children). The average Hazard Quotient (HQ) values for adults and children are generally lower than one except Mn that has average value greater than one in both age groups. However, for children, individual HQ in Fe in some of the locations are >1. The Hazard Index (HI)for adults and children ranged from low to high. The average values of Chronic Daily Intake (CDI) are generally <1. However, in children, values for Fe in some locations are >1. The average Carcinogenic Risk (CR) of Cr and Pb computed for adults and children indicated that the values are greater than the risk limit of 10-6 and 10-4. This could result in potential health risk to the consumers. The sources of these trace elements are largely from various anthropogenic activities and slightly from weathering of rocks in the study area. It is recommended that adequate and well monitored precautions need to be taken to safeguard the health of the consumers especially the children with low immunity.

Heavy metal pollution of soils is a major concern today because contamination of food chain considered as one of the major environmental pathways of human exposure leading to potential health risk.A pot experiment was carried out to investigate the transfer of Zn, Cu, Ni, Fe, Cd, Cr, Pb and Mn from non-contaminated and contaminated soils to jute leaves vegetable plant and to evaluate their associated health risk in the local population.The mean concentration of the heavy metals in jute leaves vegetable plants followed a decreasing order of Fe>Zn>Mn>Cu>Cr>Pb>Cd>Ni. Among the all heavy metals the highest transfer factor (TF) values was found for Cu (77.50-34.95) and the lowest TF value was observed for Ni(0-0.001) in jute leaves vegetables plant. The daily intake of metals (DIM) for a person through ingestion of jute leaves were in order of Fe>Mn>Zn>Cu>Cr>Pb>Ni>Cd. The values of health risk index (HRI) for the heavy metals were less than 1, therefore, no significant health risk is anticipated for the local consumers through ingestion of jute leaves.

Vegetable Samples

Ingestion of vegetables containing heavy metal is one of the main ways in which these elements enter the human body. Once entered, heavy metals are deposited in bone and fat tissues, overlapping noble minerals. Slowly released into the body, heavy metals can cause an array of diseases. This study aimed to assess the heavy metals residues in some vegetables and potential health risk among consumers within Katsina Metropolis. Six different vegetable samples comprising of cucumber (Cucumis sativus), cabbage (Brassica oleracea), lettuce (Lactuca sativa), spinach (Spinacia oleracea), red pepper (Piper nigrum) and tomato (Lycopersicum esculentus) were randomly collected from two main irrigation farmland located in Katsina Metropolis (Kofar sauri and Kofar marusa). Their level of toxic metals namely (Copper, Zinc, Cadmium, Chromium and Lead) were assessed using standard materials and methods. Results obtained were used to estimate the health risk of these heavy metals via consumption of the vegetable samples. The results from the study showed that the mean heavy metal concentration ranged between 1.10±0.00 mg/kg to 4.45±0.16 mg/kg, 1.78±0.07 mg/kg to 4.9±0.11 mg/kg, 0.02±0.00 mg/kg to 1.28±0.02 mg/kg, 1.51±0.02 mg/kg to 4.34±0.02 mg/kg and 1.05±0.01 mg/kg to 2.86±0.02 mg/kg for Cu, Zn, Cd, Cr, and Pb respectively. The concentration of Cu and Zn were found to be below permissible limit while Cd, Cr and Pb concentration exceeded the permissible limit recommended by WHO/FAO. Health risks associated with the intake of these metals were evaluated in terms of estimated daily intake (EDI), hazard quotient (HQ) and hazard index (HI). EDI value of Cu and Zn were found to be below the maximum tolerable daily intake (MTDI). The HQ of all the metals were >1, suggesting health hazards risk for the population. Moreover, HQ of Cd and Pb were greatly higher through consumption of cucumber, cabbage, lettuce and red pepper indicating significant health risks. HI was found to be higher >1 (3.32 mg/kg and 3.91 mg/kg) in adult and children respectively for consumption of spinach; however, it was much higher >1 (10.49 mg/kg and 12.4 mg/kg) in adult and children respectively for consumption of cabbage, suggesting more adverse health effects from cabbage consumption than spinach. The findings of this study shows the health risks associated with the consumption of heavy metals through the intake of some the selected vegetables within Katsina Metropolis, therefore, there is need for biomonitoring of these heavy metals in the vegetable because these are some of the main sources of food for humans in many parts of the world.

Groundwater is the most important natural source for supplying of drinking water around the world, especially in rural areas. The 14th khoroo (sub-district) of Khan-Uul district of Ulaanbaatar is only one khoroos where its inhabitants engage in animal husbandry and agriculture, which play an important role in the district’s economic growth, faces an increasing shortage of groundwater due to population and economic growth in the agriculture sector in the sub-district. In this study, we present the hydro-chemical characteristics and spatial distribution of aquifer using GIS and multivariate statistical approaches. During the sampling periods, a total of 51 groundwater samples were collected from 46 deep wells and 5 shallow wells in the area between October and November 2019. Samples included parameters of anions and cations (Na+, K+, Ca2+, Mg2+, Cl-, SO42-, NO3-, HCO3-) and EC. Data from all the samples were subject to cluster and component analysis. As a result, three clusters were defined and it was established that the dominant groundwater type is HCO3-Ca2+-Na+.  The parameter of Mg2+ and Ca2+ were not set in the permissible limits of the second and third clusters. Principal component analysis (PCA) illustrated that the northern part of the study area is greater affected to anthropogenic activities and aquifer mineralogy. Moreover, it found that Ca2+ and Mg2+ correlated with each other, which could be helpful in site specific monitoring of groundwater quality. The results of the study will contribute to management and quality control of the groundwater in the city.

Consumption of fish is a primary route of exposure to heavy metals that could be detrimental to human health due to the tendency of bioaccumulation and biomagnification along the food chain. The aim of this study was to evaluate the accumulation of heavy metals (Ni, Zn, Pb, Fe, and Cr) in two commercially available fishes, Clarias gariepinus and Parachanna obscura, and to estimate the health risks they pose to humans through consumption. Twenty-four (24) fish samples (triplicates for each month for the two species) were collected between July and October 2017. Heavy metals were identified using the atomic absorption spectrophotometer and the health risk to consumers was evaluated using Estimated Daily Intake (EDI), the Target Hazard Quotient (THQ), and the Hazard Index (HI). The THQ for the individual metals in C. gariepinus and P. obscura occurred in the decreasing order of Cr > Pb > Ni and Cr > Pb > Ni > Fe with risk values of 0.015, 0.004, and 0.001, and 0.014, 0.010, 0.002, and 0.001, respectively. The hazard index for C. gariepinus and P. obscura were 0.021 and 0.027, respectively. The values of the hazard index values of the two fish species were below the threshold value of 1, an indication of no potential health risk to consumers of the fishes. However, with the occurrence of bioaccumulation of metals in the studied fishes, regular monitoring of the river is recommended.

AbstractThis study provides valuable information on the levels of various trace metals (Pb, Cd, Hg, Zn, Cu, Cr) in meat products (baked ham, raw ham, mortadella, cured sausage, würstel, salami) from South Italy and calculates potential health risk toxicity associated with their consumption for the total population and for children. In the samples studied metal concentrations are within the permissible legal limits (Cd: 0.01–0.03 μg g−1 w.w., Hg: 0.01–0.02 μg g−1 w.w., Zn: 5.71–7.32 μg g−1 w.w., Cu: 1.08–1.21 μg g−1 w.w., Cr: 0.15–0.23 μg g−1 w.w.), except for Pb (Pb: 0.22–0.38 μg g−1 w.w.). The estimated intake values are within the provisional tolerable daily intake limits for toxic metals and recommended daily intake values for essential metals in both tested groups. The noncarcinogenic risk values of the individual metals indicate that there is no health risk, but their combined effects might constitute a potential risk for children. Furthermore, the cumulative cancer risk of all samples studied exceeds the recommended threshold risk limit (> 10−4) in both total population and children, indicating a risk of potential health problems for consumers especially for children, who are more vulnerable to toxic metal exposure.
