AbstractThe objective of the study was to determine the content of cadmium (Cd), lead (Pb), arsenic (As), aluminium (Al), thallium (Tl), antimony (Sb) and uranium (U) in the apple and orange juices and black currant nectar in relation to the kind of packaging. Also, probabilistic risk assessment (non-carcinogenic) was estimated by models including target hazard quotient (THQ and THQ*). Aluminium (Al) was present at the highest concentration in the analysed juices and nectars, with average concentration ranging from 1.34 mg/kg in orange juices (glass) to 4.26 mg/kg in black currant nectar (glass). Fruit juices and nectars kept in tetra pack packaging were characterised by elevated concentrations of Al and Sb, while the products in glass packaging contained significantly higher concentrations of As compared with the products in tetra pack packaging. Although the average concentrations of trace elements were lower than the standard limit, exposure to non-carcinogenic factors was demonstrated.

The objective of the study was to determine the content of cobalt, silver, tin, antimony, lead, mercury, cadmium, arsenic, vanadium, chromium, manganese, nickel, and uranium in canned meat and canned fish by means of ICP-MS apparatus and mercury analyzer. Also, probabilistic risk assessment (non carcinogenic) was estimated by models including target hazard quotient (THQ). It was found that Mn was the element with the highest concentration in the analyzed products, with average concentration of 0.216 mg·kg−1 in canned meat and 1.196 mg·kg−1 in canned fish. The average contents of other elements were as follows (respectively, for canned meat and fish): Co 0.018 and 0.028 mg·kg−1, Ag 0.0386 and 0.0053 mg·kg−1, Sn 0.059 and 0.200 mg·kg−1, Sb 0.0268 and 0.0377 mg·kg−1, Pb 0.202 and 0.068 mg·kg−1, Hg 0.00003 and 0.02676 mg·kg−1, Cd 0.00496 and 0.0202 mg·kg−1, As 0.002 and 0.857 mg·kg−1, V 0.0003 and 0.095 mg·kg−1, Cr 0.244 and 0.590 mg·kg−1, Mn 0.216 and 1.196 mg·kg−1, Ni 0.004 and 0.088 mg·kg−1, and U < LOQ and 0.047 mg·kg−1. The concentration of As was the highest among other toxic elements in canned fish; therefore, the THQ value of this element revealed the highest level amounting up to 0.77576 (THQmax).

The presented study was aimed at the determination of the level of contamination with heavy metals (Cd, Pb, As, and Hg) in 240 samples of plant materials, i.e., herbal raw materials, spices, tea, and coffee. Moreover, a probabilistic risk assessment (noncarcinogenic and carcinogenic risks) was estimated by models including target hazard quotient (THQ) and cancer risk (CR). The samples were subjected to microwave mineralisation with the use of HNO3 (65%), while the determination of the content of the elements was performed with the use of inductively coupled plasma mass spectrometer (ICP–MS) and a mercury analyser. The element which was characterised by the highest level of accumulation in the analysed samples was lead (from 0.010 to 5.680 mg/kg). Among the heavy metals under analysis, the lowest concentration was noted in the case of mercury (from 0.005 to 0.030 mg/kg). A notably higher level of contamination with heavy metals was noted in the analysed samples of herbs and spices (0.005–5.680 mg/kg), compared to samples of tea and coffee (0.005–0.791 mg/kg). According to the guidelines of the World Health Organisation (WHO) concerning the limits of contamination of samples of herbal raw materials with heavy metals, lead levels exceeding the limits were only noted in 24 samples of herbs (18%). In all of the analysed samples of spices, tea, and coffee, no instances of exceeded limits were noted for any of the analysed heavy metals. The values of TTHQmax (in relation to the consumption of the analysed products) were as follows: up to 4.23 × 10−2 for spices, up to 2.51 × 10−1 for herbs, up to 4.03 × 10−2 for China tea, and up to 1.25 × 10−1 for roasted coffee beans. As the value of THQ ≤1, there is no probability of the appearance of undesirable effects related to the consumption of the analysed group of raw materials and products of plant origin. The CR value for As (max. value) was 1.29 × 10−5, which is lower than the maximum acceptable level of 1 × 10−4 suggested by United States Environmental Protection Agency (USEPA).

Abstract Introduction: Geophagia although pleasurable and somewhat a necessity among pregnant women, also comes along with its own attendant problems such as exposure to potentially hazardous substances like bacteria, fungi, helminthes and ova, radioactive materials, and toxic elemental minerals in the soil depending on the geographical location.Methodology: This study evaluated the potential health risk involved during the exposure of pregnant women to toxic elemental minerals via the consumption of clay as pica (geophagia). Elemental mineral analysis was carried out using Buck Scientific 210VGP Flame Atomic Absorption Spectrophotometer (Buck Scientific, Inc. East Norwalk, USA). Risk assessment methods were also used to ascertain the various risks factors and the overall risk level.Results: Concentrations of the macro elements investigated were 1.38 ± 1.5, 2.40± 1.5, 7.74± 1.5, 4.01± 1.0, 13.24± 2.2 and 13.76± 2.1 mg/Kg for iron (Fe), copper (Cu), zinc (Zn), potassium (K), magnesium (Mg) and sodium (Na) respectively. While that for the micro elements were 1.63± 0.03 µg/Kg, 4.72±0.8, 0.53±0.02 and 1.85±0.3 mg/kg respectively for arsenic (As), manganese (Mn), lead (Pb) and nickel (Ni). Estimated Daily Intake (EDI), Hazard Quotient (HQ), Target Hazard Quotient (THQ) and Total Target Hazard Quotient (TTHQ) values ranged 0.611- 5.44 (mg/kg Bw/day), 6.26x10-4 – 106.5, 0.067-10.34 and 15 respectively.Conclusion: There is the likelihood of posing adverse health problems when clay samples obtained from Anfoega which is sited in the Volta region of Ghana is consumed due to the fact that the HQ’s of these elemental minerals were >1 which points to high content of Manganese (Mn) and Nickel (Ni). It is also likely to cause adverse health problems in an individual’s life time since THQ for Arsenic, Lead and Nickel were above 1. Ultimately, the cumulative effect of these toxicants were exceedingly great (≤ 15) which implied a high level of unsafety associated with this clay. Per the results from this study, it is not safe for pregnant women to consume clay as pica since these toxic elements may cause detrimental effects on the foetus of the unborn child.

A risk assessment, related to the consumption of farmed sea bass, was carried out by meta-analysis, taking into account the concentration of trace metals (Cd, Pb, Hg) reported in the literature, the estimated weekly intake (EWI), the provisional tolerable weekly intake (PTWI), and the target hazard quotient (THQ). The concentrations of Cd, Pb, and Hg in farmed sea bass marketed in Sicily (Southern Italy) were also assessed by inductively coupled plasma mass spectrometry (ICP-MS) and atomic absorption spectroscopy (AAS) to have screening data for the comparison with literature results. In any case, the results obtained by meta-analysis and by screening were lower than the pre-established legal limits for each metal. The meta-analysis results showed very low levels of Cd (0.031 μg g–1 w.w.), Pb (0.110 μg g–1 w.w.), and Hg (0.023 μg g–1 w.w.). The EWI estimation confirmed safety limits for human health (0.004, 0.015, and 0.003 μg kg–1 for Cd, Pb, and Hg, respectively). Even the THQ demonstrated that farmed sea bass represent a secure food for humans (0.0006, 0.0005, and 0.0048 for Cd, Pb, and Hg, respectively). The comparison with our screening data showed a significant difference only for the Pb levels (p &lt; 0.05). The results obtained were compared with the same indexes relative to other food types (meat, cereals, vegetables, etc.). The EWI and THQ calculated were always lower than same indexes relative to other food types considered.

Ogunpa River receives municipal and industrial waste discharge from its catchments and these have depleted the quality of the water. Hence, this research examines the preliminary environmental impacts and health implications of some trace elements in the water using Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) laboratory technique. Average values of Al, Ba, Fe, Mn, Ni and Pb are above the recommended limits of WHO. The CF showed that the trace elements varied from considerable contamination factor to very high contamination factor and the degree of contamination varied from 1023 to 11640. The hazard quotient computed for the adults is generally less than unity except Pb that has average value of 1.27. In children, the computed hazard quotient on the average ranges from 0.000572 to 4.04. Al, As, Ba, Cr, Cu, Ni, Zn and Cd have their average values less than unity respectively, while Fe, Mn and Pb has their average values greater than one. The Hazard Index (HI) in adults and children are greater than one. Carcinogenic risk assessment was computed for Cr, Pb and Cd which was greater than 10-6 in children and adult. Only Cd in adult was less than the prescribed limit of 10-6. Effort should be made to checkmate indiscriminate dumping of refuse and sewages into the water body as these could serve as pollutants to other adjourning rivers and main water bodies. In conclusion, the water is not fit for domestic, agricultural and probably industrial uses because of its health implications on consumption

Water is an important asset for the maintenance of life and socioeconomic development. Aquatic environments have been anthropized, receiving a large polluting load, mainly from trace elements.This study investigates the occurrence of health risks caused by 15 trace elements in the surface water of João Leite stream. Health risk indices were evaluated as average daily dose (ADD), hazard quotient (HQ), hazard index and carcinogenic risk. The risk analysis to human health of the stream João Leite water, indicated that the ADDingestion for the adults had the highest for Fe 1.86E-00 µg/kg/day and lower value for Be 8.0E-05 µg/kg/day. On the other hand, of ADDdermal the highest value was for Fe 5.02E-02 µg/kg/day and, the smallest for Sb 1.54E-05 µg/kg/day. For children to ADDingestion obtained was obtained the highest Fe value 2.60E-00 µg/kg/day and smaller for Be 1.12E-04 µg/kg/day. For ADDdermal the highest value was for Fe 8.58E-02 µg/kg/day and smaller for Sb 2.64E-05 µg/kg/day. HQ for adults ranged from 1.61E-05 to 2.97E-01 for HQingestion and 7.71E-06 to 1.01E-01 for HQdermal. For children 2.25E-05 to 3.74E-01 for HQingestion and 1.32E-05 to 1.73E-01 for HQdermal. The health risk assessment showed that for children, the trace elements present in water have a potentially adverse effect on non-carcinogenic health. The carcinogenic risks were unacceptable for both children and adults. Thus, it is recommended that the use of these waters be limited and that measures be taken to minimize pollution by trace elements.

Crustaceans are known for their trace element bioaccumulation abilities. Muscle tissues of lagoon crab, marine crab, pink shrimp and mantis shrimp marketed for consumption in Nigeria were analyzed for Mn, Fe, Cu, Zn, Hg and Cr levels using standard methods. Muscle levels in mg kg-1 of Mn (0.03±0.00 in lagoon crab), Fe (0.072±0.01 in mantis shrimp), Cu (0.344±0.01 in lagoon crab) and Zn (0.073±0.00 in mantis shrimp) were significantly different (p<0.05) from their corresponding values in other examined crustaceans. The mean values of Cr and Hg were not significantly different across samples. The estimated daily intake of trace element (mg person-1day-1) revealed that Hg (0.000001) in marine crab contributed the lowest daily intake while Zn (0.000226) in lagoon crab contributed the highest daily intake. Total hazard quotient (THQ) values for the trace elements followed descending order of Hg > Cu > Zn > Fe > Mn > Cr. Lagoon crab showed the highest total hazard index among the organisms with 44.80 %, while the least was observed in mantis shrimp with 13.30 %. It is concluded that, as far as human health is concerned, the mean elemental levels in the muscle tissues of the organisms examined pose no danger (THQ < 1).

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.
