Heavy metal mediated toxicity is associated with several health risks. In this research, heavy metal contents in selected dairy products such as Cheese, Ghee (Local processed dairy product) and Butter were determined and studied their effects on human health. From the results, it was determined that, Cu had the highest concentration and daily intake rate in Cheese, Ghee and Butter samples; while Pb had the lowest concentration and daily intake rate in Cheese and Butter samples. The estimated daily intake (EDI) values of all these metals were less than the permissible value. Also the results of THQ (Target hazard quotient), TTHQ (Total target hazard quotient) and TCR (Target Carcinogenic risk)suggested that, all of these values of these dairy product samples were less than the risk value. Our current study indicated that there is no chance of any kind of health risk through the consumption of these dairy products.

Human Risk

Heavy metals pose a threat to human health and their presence in specific matrices is anthropogenic. The work focuses on the penetration of the food chain through the ingestion of mollusk proteins. This study evaluated the composition of heavy metals (Cd, Cr, Mn, Pb and Zn) in three species of mollusks (Limicolaria flammea, Viviparus contectus, Egeria radiata) from Yenagoa, Bayelsa State, Nigeria and the health risk associated with their consumption. Heavy metals concentration was determined by Atomic Absorption Spectrophotometer (AAS). Health risk associated with consumption of the samples were assessed by Estimated Daily Intake (EDI), target Hazard Quotient (THQ) and Carcinogenic Risk (CR). EDI, THQ and CR were done by calculation following standards. Heavy metals concentration range in the samples were: Cd (0.289±0.00 mg/kg - 0.667±0.00 mg/kg), Mn (0.816±0.00 mg/kg - 0.934±0.00 mg/kg), Pb (0.082±0.00 mg/kg - 0.092±0.00 mg/kg) and Zn (4.114±0.00 mg/kg - 8.534±0.00 mg/kg); Cr was not detected in neither of the samples.  EDI of heavy metals through consumption of these samples were within acceptable limits for all heavy metals detected. THQ ranges were as follows: Cd (0.4949-1.1420), Mn (0.000017-0.000019), Pb (0.0401 - 0.0450) and Zn (0.0016 - 0.0066).  THQ values indicate that there is no human risk concern of risk for humans except Cd (in E. radiata). CR values for Cd were as follows: L. flammea (3.8×10-3), E. radiata (4.34×10-4) and V. contectus (1.88×10-4). CR values were within acceptable limits with the exception of Cd in L. flammea. The present study shows that the samples contained detectable levels of heavy metals however their consumption do not pose any form of health risk with the except for Cd in L. flammea, hence the carcinogenic role of L. flammea stands out for its high content of Cd.

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.

Pesticides Residues

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.

This study aimed to analyse ten trace metal concentrations in the edible part of the freshwater clam Corbicula javanica and to provide a critical assessment of the potential risks to human health through consumption of this clam as food based on well-established indices and food safety guidelines. The clams were captured from a pristine original site and transplanted to other sites with different environmental qualities. The trace metal levels in the edible total soft tissue (TST) of the clam were below those of the food safety guidelines referred to except for Pb, which exceeded the permissible limit set by the European Commission (2006) and the US Food and Drug Administration/ Center for Food Safety and Applied Nutrition); Interstate Shellfish Sanitation Conference. (USFDA/CFSAN; ISSC) (2007). The estimated daily intake (EDI) values of the clam were found to be lower than the oral reference dose and the calculated target hazard quotient (THQ) and total THQ were found to be less than 1. Therefore, in conclusion, the human health risk for consumption of TST of C. javanica at both average and high-level were insignificant regardless of the environment it was exposed to.

This study aimed to investigate the concentrations of copper (Cu), zinc (Zn), nickel (Ni), lead (Pb) and iron (Fe) in different parts of guava (pulps, peels and seeds) and its topsoil collected from Kluang, Malaysia, and to assess their effects on human health. The level of metals was determined using acid digestion method and atomic absorption spectrometry. The result showed that the concentrations of Cu, Zn and Pb in all parts of guava were above the World Health Organization (WHO) permissible limits. However, the value of heavy metals in the topsoil were below the WHO limit. The concentration order of the metals in the guava's pulps was Fe > Cu > Zn > Pb > Ni. The contamination factor (Cf ) calculated from the topsoil were low for Cu, Zn and Ni and moderate for Pb. However, potential ecological risk (Er) of individual metal ranged from 0.25-7.58 for Cu, Zn, Pb and Ni was low. The potential non-carcinogenic health risk for consumers was assessed using estimated daily intake (EDI) and target hazard quotient (THQ). The contribution of heavy metals to the EDI for all consumers followed the order of Fe > Cu > Zn > Pb > Ni. The THQ values are all below 1 for all five metals tested, indicating no potential risk to the consumers. We suggest that the Kluang's guava is safe to consume. However, regular monitoring and human health risk assessment of heavy metals in the guava is recommended to be carried out.

Abstract Chicken meat and hen egg are very popular foodstuffs around the world and highly consumed as curry, fast food, processed food, etc. assuming a promising source of protein. In the present study, the concentrations of Pb, Cd, Cr, As, Hg, Mn, Fe, and Zn in nationally representative samples of chicken meat and hen egg were determined and found in the range of 0.03–2.73, 0.01–0.015, 0.025–0.67, 0.04–0.06, 0.01–0.015, 0.15–0.63, 2.50–38.6, and 1.02–19.4 mg/kg-fw, respectively. The results demonstrated that only Pb exceeded the maximum allowable concentration (MAC) for dietary food. Multivariate statistical analyses depicted that anthropogenic activities were the major source of heavy metals in the investigated foodstuffs. Human health risks associated with the dietary intake of these metals through the consumption of chicken meat and hen egg were evaluated in terms of estimated daily intake (EDI), non-carcinogenic risk of individual heavy metal by target hazard quotient (THQ), total target hazard quotient (TTHQ) for combined metals and carcinogenic risk (CR) for lifetime exposure. The calculated values of EDI, THQ, TTHQ, and CR were below their respective permissible benchmarks indicating the safe consumption of the investigated foodstuffs with respect to heavy metal contamination.

Heavy metals are of serious concern for human health and food security. The risk to human health is directly related to soil and water pollution, which enter the food chain (vegetables and fruits). The current study was designed to investigate the heavy metals (Cr, Pb, Ni, Cd, and Zn) concentrations in five vegetables (Potato, Tomato, Turnip, Onion & Taro) and five fruits (Banana, Apple, Grapes, Pomegranate, and Guava) samples. We also estimated metal concentrations in water and soil samples. Torkham, a border region between Afghanistan and Pakistan, was selected for the purpose. The analysis was performed on Atomic Absorption Spectroscopy (AAS, Perkin- Elmer 700). In vegetables, the highest Pb and Ni were recorded in Potatoes (0.34 ± 0.066) and Onions (0.278 ± 0.021). While in tomatoes, the highest concentrations of Cd (0.90± 0.115), Zn (0.726 ± 0.008), and Cr (1.761 ± 0.028) were noted. While, in fruits the highest levels of Pb (0.32± 0.03), Cd (0.61 ± 0.0119), Zn (0.357 ± 0.0047) and Ni (0.111 ± 0.0128), while in apples we noted the highest Cr levels (0.789 ± 0.0452). We compared the metal concentrations with permissible limits set by World Health Organization/Food and Agricultural Organization (WHO/FAO). In the majority of the samples, the metal levels exceeded the permissible limits, while few were found within the safe limits. Based on heavy metals concentrations in soil, water, vegetables, and fruit samples. We calculated the health risk assessment, i.e., daily intake of metals (DIM) estimated daily intake (EDI), target hazard quotient (THQ), total target hazard quotient (TTHQ), carcinogenic risk (CR), health risk index (HRI) and contamination factor (CF). The EDI for Ni and Zn was in the safest region. While for Cd and Pb, the highest EDI was recorded in tomatoes (0.394) and guava (0.303), respectively. Similarly, Cr poses’ serious risk with the highest EDI in tomatoes (0.771), apples (0.563), turnip (0.393), guava (0.282), and banana (0.263). If HRI, THQ THQ, and TTHQ are less than one (< 1), it means the exposed populations are not at risk. In the present HRI, THQ and TTHQ were found to be less than one. The contamination factor for Ni and Zn was found to be considerable (CF<6), while Pb, Cd, and Cr presented the highest contamination degree (CF>6). This study suggested that some samples may impose a certain degree of potential health risk. It is required that proper action should be taken to avoid chronic exposure and consequent adverse health effects.

Three edible mushroom species (Imlera badia, Boletus subtomentosus, Xerocomellus chrysenteron) sampled in 60 different localities of Slovakia were evaluated to determine health risks (associated with mercury content) arising from their consumption. Total content of mercury in soil and mushroom samples was determined by an AMA-254 analyzer. Soil pollution by mercury was evaluated by contamination factor (Cf), pollution load index (PLI), and geoaccumulation index (Igeo). Bioaccumulation factor (BAF), translocation factor (Qc/s), provisional tolerably weekly intake (%PTWI), estimated daily intake (EDI), and target hazard quotient (THQ) were used to describe and compare uptake and transition abilities of mushrooms, and the health risk arising from mushroom consumption. Mercury content in soil significantly influences the content of mercury in mushroom fruiting body parts. Caps and stipes of Boletus subtomentosus were found to be the best mercury accumulator. According to the EDI, consumption of the evaluated mushroom species represents a serious threat for adults and children. The lowest values of THQ were found for Xerocomellus chysenteron.

The present study was conducted to determine daily intake of cadmium (Cd), copper (Cu), and lead (Pb) and to assess noncarcinogenic human health risk caused by these trace metals in the commonly consumed fish species ( Oreochromis niloticus, Rastrineobola argentea, Lates niloticus, and Protopterus aethiopicus) in Nakuru town, Kenya. Trace metal determination in the composite samples of the commonly consumed fish species was done using flame atomic absorption spectrophotometer. Cd, Cu, and Pb content in the muscle tissues of the commonly consumed fish species ranged from 0.11 ± 0.045 to 1.11 ± 0.931 mg kg−1 for Cd, 0.48 ± 0.013 to 3.00 ± 0.009 mg kg−1 for Cu, and 3.42 ± 0.045 to 12.78 ± 0.108 mg kg−1 for Pb. Cu concentrations were within Food and Agriculture Organization (FAO) recommended limits for this trace metal in fish. In contrast, Cd and Pb had values above their respective permissible limits in fish. The assessment of human exposure to trace metals indicated that exposure doses of Cd and Cu were safe for fish consumers. Conversely, target hazard quotient (THQ) values of Pb suggested possible health risks for consumers of the commonly consumed fish species in Nakuru town, Kenya.
