Abstract Potential toxic metals (PTEs) accumulation in soil and water is one of the major sources of food crop contamination. PTEs remediation from soil can be enhanced by addition of organic matter to the growing media. An experiment was carried out to investigate the effect of different organic amendments on the accumulation of PTEs in pea plant grown on mine degraded soils. Mining soils from chromite mine (CM), soap stone mine (SSM), manganese mine (MM) and quartz mine (QM) were mixed with vermicompost (VC), leaf mould (LC) and spent mushroom compost (SMC) along with garden soil at 1:1:1 ratio. Various growth and yield related attributes of pea plant as well as PTEs concentrations in soil and plants were studied. The highest Cd (2.62 mg kg−1) and Cr (13.6 mg kg−1) concentration was reported in CM soil, while Pb (23.3 mg kg−1) and Mn (59.2 mg kg−1) concentration in SSM and MM soil, respectively. Mining soils significantly reduced the plant growth and yield, while organic amendments reduced the PTEs availability and increased pea plant growth. Comparing the various organic fertilizers used, it was observed that VC efficiently reduced Cd, Cr, Pb and Mn uptake by pea plant, subsequently, improved pea plant growth. In order to assess the effects of various amendments on PTEs health risk reduction various risk indices including, plant trafser factor, average daily intake, health risk, target hazard quotient and target cancer risk were also calculated and the results revealed that application of compost particularly VC significantly reduced the dietary intake and health risks of PTEs.

Important Pathway

Fish and marine mammal consumption are an important pathway for human exposure to mercury. The low mercury content in shellfish poses a low mercury health risk to people who consume shellfish. The objectives of this study are to detect mercury concentrations in different species of shellfish and to calculate the mercury health risk from shellfish consumption among traditional residents near northern Jiaozhou Bay. A total of 356 shellfish samples, which comprised 7 species from 5 different places in northern Jiaozhou Bay, were collected from April to June in 2012. The average mercury content in the collected shellfish ranged from 0.024 mg·kg−1to 0.452 mg·kg−1. A total of 44 shellfish samples (12.36%) had mercury levels exceeding the national pollution-free aquatic products limit (0.3 mg·kg−1). Generally, the viscus had the highest mercury content among all parts of the shellfish. A positive correlation between mercury content and total weight/edible part weight was found in most species of the collected shellfish. The results showed that shellfish consumption resulted in the lower risk of mercury exposure to residents based on the calculation of daily intake (DI) and target hazard quotient (THQ).

This study was conducted to determine the heavy metals concentration in Hibiscus leaves cultivated in Katsina State Nigeria. The objectives were mainly to detect the presence of heavy metals in the cultivated Hibiscus leaves in the study area, compare the concentration of heavy metals in samples in relation to the permissible limits specified by WHO/FAO/USEPA Standards. Samples of cultivated Hibiscus leaves were collected in the year 2017 from the selected area.  Analysis for the concentration of these heavy metals; Cr, Cd, Fe, Ni, Mn, Pb and Zn was conducted by the use of AAS (by Atomic Absorption Spectrophotometry) method. The health risks to the local inhabitants from the consumption of the samples were evaluated based on the Target Hazard Quotient (THQ). The possibility of cancer risks for the adult and children population through intake of carcinogenic heavy metals in the samples was estimated using the Incremental Lifetime Cancer Risk (ILCR). Results from this study shows that with the exception of Pb with mean concentration of (0.508-0.978), the mean concentration (mg/kg) range values of Cr (0.135-0.261), Cd (0.042-0.051), Fe (0.684-0.978) and Zn (1.048-1.208) in the samples were generally lower than the USEPA, WHO/FAO maximum permissive limits. The results have indicated that the estimated daily intake (EDI) of the heavy metals were lower than the tolerable daily intake limit set by the USEPA in both samples and the health risk index (HRI) for all the heavy metals were <1. The target hazard quotient (THQ) for the samples for both the adult and children population was in the decreasing order of Zn>Pb>Fe>Cr>Cd. ILCR for Cd is below the threshold risk limit (>10−5) and ILCR for Pb reached the moderate risk limit (>10−3) in all the studied samples in adults, While in children ILCR for both Pb and Cd in samples from Dabai, Daura, Funtua, Matazu and Zango for all samples have reached the moderate risk limit (>10−3), while the ILCR for Pb in samples from Birchi, Dutsinma, Kafur, Katsina and Malunfashi were beyond the moderate risk level (>10−2). The sampling area trend of risk for developing cancer as a result of consuming the studied samples showed: Funtua > Daura > Dutsinma > Katsina > Malunfashi > Matazu > Zango > Ingawa > Kafur > Dabai > Birchi for both adult and children, cumulative cancer risk (∑ILCR) of all the studied Hibiscus samples have reached the moderate risk limit (>10−3) in adult. While in children with the exception of the sample from Birchi, Dabai and Kafur which are within the moderate cancer risk (>10−3) limit, all other samples were beyond the moderate cancer risk (>10−2) limit. The study suggests that consumption of the studied samples in Katsina state is of public health concern as they may contribute to the population cancer burden.

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.

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.

This study assessed health risk assessment of heavy metals in cocoyam from three quarry sites in Akamkpa LGA, Cross River State, Nigeria. Cocoyam tubers were obtained from three quarry sites in Oban Okoroba, each 4.5 kilometers apart and 20 kilometers from the control site. Cocoyam tubers were obtained from 0km, 0.2km, 0.4km, and 0.6km. Atomic Absorption Spectrophotometry (AAS) was used to determine the content of Lead (Pb), Cadmium (Cd), Copper (Cu), Arsenic (As) and Manganese (Mn), showing relative abundance across all sites and samples in the sequence Mn > Cu > Pb > As > Cd. Quarry site D had highest levels of Mn, As and Cu (50.003 ± 5.478 mgkg-1, 0.207 ± 0.184 and 4.522 ± 1.204mgkg-1). Quarry site C and B respectively had the highest levels of Pb and Cd (1.136 ± 0.267 mgkg-1 and 0.041 ± 0.028 mgkg-1). Results of Estimated Daily Intake (EDI), Target Hazard Quotient (THQ) and Life Carcinogenic Risk (LCR) showed ingestion of cocoyam tubers from Old Netim is safe and devoid of non-carcinogenic and carcinogenic risks. THI on the other hand revealed non-carcinogenic threat may result from prolonged ingestion of cocoyam tubers cultivated within quarry sites in Old Netim.

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.

This study aimed to investigate the concentration of heavy metals (Cu, Zn, Pb, and Cd) in the seawater, sediment, and soft parts of the marine mussels (Perna viridis, Meretrix sp., and Anadara granosa), as well as to evaluate its health risk of consumption from Madura Strait, Indonesia. The seawater, sediment, and marine mussels were obtained from four sites and heavy metal concentrations were analyzed using Atomic Absorption Spectroscopy. In the seawater, heavy metals were in the order of Cu, Pb, Cd, and Zn from the highest to the lowest concentration respectively, while they went down in the order of Zn, Cu, Pb, and Cd in the sediment respectively. Excluding the Pb, higher Cu and Zn concentrations were observed in marine mussels than in seawater and sediments (BAF> 1). Furthermore, it was proven that Cu and Zn were considered as essential metals and required for metabolism, while Pb and Cd were non-essential metals which their biological functions were unknown. The Estimated Daily Intake (EDI) of the marine mussels was lower than the oral reference dose (ORD) and low values of target hazard quotient (THQ < 1) had shown that the consumption of mussels containing heavy metals would not cause significant health risks to humans. The health risk assessment indexes showed low values, which meant insignificant health hazard. However, long-term exposure and the impact of consuming mussels containing heavy metals may require additional investigation

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.

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.
