Air quality deterioration is a major environmental problem in Indonesia. This study evaluated the levels and health risks of potentially toxic elements (PTEs) in Maros Regency, Indonesia. Total suspended particulate matter was collected from industrial areas for PTE (Al, Pb, Cr, Cu, Ni, As and Zn) analysis using inductively coupled plasma optical emission spectrometry (ICP-OES). Samples were collected from six critical areas in the Bantimurung region as that is where marble, cement and limestone industries are located. A calculation of the non-carcinogenic and cancer risks was performed to determine the potential health exposures in adults and children. A Monte Carlo simulation with 10,000 iterations and a sensitivity analysis was carried out to identify the risk probability and the most sensitive variable contributing to cancer risk from PTE exposure in humans. The results showed that the concentration of PTEs decreased in the order of Zn > Al > Cr > Pb > Cu > Ni > As in the wet season, and Zn > Al > Pb > As > Cr > Cu > Ni in the dry season. The hazard index (HI) value for children was 2.12, indicating a high non-carcinogenic risk for children. The total cancer risk (TCR) values in adults and children were 3.11 × 10−5 and 1.32 × 10−4, respectively, implying that both are at risk for developing cancer. The variables with the most contribution to cancer risk from As, Cr and Pb exposure in adults and children were As concentration (33.9% and 41.0%); exposure duration (ED) (34.3%) and SA (40.7%); and SA (98.7 % and 45.4%), respectively. These findings could be used as the scientific basis for public health intervention and to raise awareness of the harmful health effects of particulate bound PTEs

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.

The content of macro- and microelements in dry samples of mushrooms of the species Macrolepiota procera, Boletus edulis and Cantharellus cibarius, collected at different areas in Bosnia and Herzegovina, was determined using the ICP-OES method (inductively coupled plasma optical emission spectrometry). Of the macroelements, K is the most represented, followed by S, P, Mg, and the least represented Ca and Na. Zn is the most represented of the essential microelements, followed by Fe, Se, Cu, Mn and Co. Al is the most abundant of the other trace elements followed by Ni and Cr. Of the toxic metals, the most represented is Cd, followed by Pb and As. There are differences in the concentration of micro- and macroelements in the mushrooms analysed, depending on the area from which they were collected because natural geology and geochemistry influence the content of macro- and microelements in wild edible mushrooms. The results show that the analysed mushrooms can be considered a good source of essential elements. The study also assessed potential health risks of heavy metals and the target hazard quotient (THQ) for As, Cd, Pb, Cu, Zn, Ni and Cr in the analysed mushrooms was lower than the safe level. The carcinogenic risk index revealed that Cd and Ni are the most prevalent pollutants in the mushrooms studied.

This study evaluated chromium (Cr), arsenic (As), cadmium (Cd), and lead (Pb) contamination in raw milk from industrial areas in China, identified the possible pathways of heavy metals from the environment to raw milk, and made a risk assessment of the consumption of heavy metals from milk consumption. The Cr, As, Cd, and Pb concentrations in raw milk, water and silage were analyzed using inductively coupled plasma mass spectrometry. The Cr and As in soil were analyzed by flame atomic absorption spectrometry and atomic fluorescence spectrometry, respectively. Cd and Pb in soil were determined by a Graphite furnace atomic absorption spectrophotometer. The Cr and As concentrations in milk from industrial areas were 2.41 ± 2.12 and 0.44 ± 0.31 μg/kg, respectively, which were significantly higher (p < 0.01) than those from non-industrial areas, which had levels of 1.10 ± 0.15 and 0.25 ± 0.09 μg/kg, respectively. Chromium was mainly transferred through the soil-silage-milk pathway, As was transferred through the water-silage-milk pathway, while Cd was mainly transferred through the soil (water)-silage-milk pathway. The contributions of each metal to the overall hazard index (HI) followed a descending order of As, Cr, Pb, and Cd, with values of 46.64%, 25.54%, 24.30%, and 3.52%, respectively. Children were at higher risk than adults.

Accumulation and risk assessment of metals in sediments and zoobenthos (Bellamya aeruginosa and Corbicula fluminea) from Lake Taihu were studied. Results showed that metal (Cr, Cd, Cu, Zn, Pb and Ni) concentrations in Lake Taihu varied greatly, and Cd in the Zhushan Bay showed higher bioavailability compared to the other metals studied. The spatial distribution of metals in B. aeruginosa and C. fluminea was similar to that in sediments. Zn and Cu exhibited the higher mean concentration in B. aeruginosa and C. fluminea, which was in good accordance with its higher content in surrounding sediment. Labile fractions (i.e., acid-soluble (F1), reducible (F2) and F1 + F2) of Cu and Zn in sediments showed a significant positive correlation with them in B. aeruginosa (P &lt; 0.01); no correlation relationship was found for metals (Cd, Cr, Cu, Zn, Pb and Ni) between in the tissue of C. fluminea and in sediments. The results of ecological risk assessment showed that Zhushan Bay was seriously contaminated by metal Cd, as it made the main contribution of all the metals. Total target hazard quotients indicated that adults and children both had potential health risk through consuming C. fluminea. Hazard index values suggested that adults and children might experience adverse health effects through consuming B. aeruginosa and C. fluminea.

Vegetable fields in Katsina State are increasingly being loaded with heavy metals through various pollution sources such as agricultural activities mining and traffic. Onion bulb samples from the three senatorial zones that constitute to make up Katsina state in the North West of Nigeria were collected and the concentrations of seven heavy metals (Pb, Cd, Cr, Fe, Zn, Mn and Ni) in all the samples were determined by atomic absorption spectrometry. The health risk assessment methods developed by the United States Environmental Protection Agency (US EPA) were employed to explore the potential health hazards of heavy metals in the samples on the children and adult population. The highest mean concentration (mg/kg) was observed for Fe, followed by Pb, Zn and Mn. While Cd has the lowest concentration with the heavy metals Cr and Ni being below detection level (BDL). Overall hazard index (Hi) for the heavy metals were within the safety limit. The overall cancer risk to the adults based on pseudo-total metal concentrations exceeded the target value, mainly contributed by Pb.  Mn and Zn were the primary heavy metals posing non-cancer risks while Pb caused the greatest cancer risk. It was concluded that consumption of the onion samples from Katsina State may contribute to the population cancer burden.

Arsenic is a carcinogenic and toxic element that possesses a high health risk from its presence in crops, water, and soil. The present study has been conducted by fenugreek (Trigonella foenum-granecum) seeds which is a very common spice used for cooking, especially in India. An equal number of seeds have been germinated in laboratory conditions. Three concentrations e.g. 1, 2, and, 3 mg/L of arsenite (As+3) and arsenate (As+5) salt solutions were used throughout the experiments for the treatment of plants. After 10 days of germination, the concentration of the arsenic accumulated into the plant edible parts was estimated and health risk was assessed. Effects of arsenic concentration were observed through estimating the total chlorophyll (a, b, c), carotenoid content, and taking the fresh weight and dry weight of both the control and treatment plants. The results of the biochemical analysis revealed that chlorophyll and carotenoid contents were decreased than that of control plants. Moreover, fresh weight and dry weight results also showed lower values in treatments than in controls. The bioaccumulation factor results demonstrated that an increased level of soil arsenic doesn’t certainly result in high arsenic uptake by the Fenugreek plants. From the concentration estimated in the plant body, the health risk was assessed in adults and children and found that both adults and children having a potential health risk upon consumption of fenugreek. Moreover, Incremental Life Time Cancer Risk was found high (< 10-4) which indicates the presence of potential cancer risk. Hence, it is possible to conclude from the present study that fenugreek can bio-accumulate arsenic and it may be used as an indicator plant for arsenic-contaminated areas.

Polycyclic Aromatic Hydrocarbons (PAHs) were assessed in shellfishes (whelk, oyster and periwinkle) from Kula, Rivers State, Nigeria. The PAHs determination was done using gas chromatography (GC) coupled with flame ionization detector (FID) (Hewlett Packard, Wilmington, DE, USA), powered with HP chemstation Rev. A09:01 (10206) software. Human health risk assessment models based on United States Environmental Protection Agency (USEPA) was used to characterize risks of PAHs exposure to non cancer (Hazard Index) while and excess cancer risk (ECR). From the results, Benzo [a] Anthrancene (BaA) had highest concentrations in whelk (0.689±0.003) and Periwinkle (0.930±0.001) while Naphthalene had highest concentration in oyster (2.000±0.000). The Total concentration of PAHs in µ g/kg for whelk, oyster and periwinkle were 1.797±0.013, 3.977 ±0.024 and 1.564±0.017 while the estimated daily intake (EDI) of PAHs (mg/kg/day) via consumption of shell fish ranged from 2.00x10-4 to 6.40x10-2, 7.0x10-4 to 1.86 x10-1 and 0 to 8.64x10-2 far above oral reference dose (RFD) respectively. The toxic equivalents (TEQs) values were 1.276x10-4, 1.252x10-4 and 4.034x10-4 for whelk, oyster and periwinkle respectively, were significantly (p<0.05) higher than the screening value (SV) for shellfish 1.81x10-5mg/kg. The estimated excess cancer risk (ECR) obtained for whelk was (3.0x10-4), oyster (2.00x10-4) and periwinkle (3.24x10-4). These values were far above the USEPA acceptable (1x10-4). From this study, it can be deduced that bioaccumulation of PAHs in the shellfish is a potential health hazard to consumers. Carcinogenic indices indicated that daily Intake of contaminated shellfishes exposures the local populace to cancer risks.

ABSTRACT This study investigated the levels of lead, selenium, arsenic, iron, manganese, copper, zinc, chromium, cadmium, and nickel in honey and their potential health risks to consumers, using standard protocols. The honey samples were obtained from apiary farms at nine different locations in southeast Nigeria. They were digested at optimal conditions and analyzed using a flame atomic absorption spectrophotometer. Levels of the studied elements in the honey were found to vary relative to the sample source; however, all were below European Commission maximum permissible limits, with the exception of lead, whose level in some samples exceeded the recommended set limit. Estimated daily intakes of the elements via ingestion of the honey were all below the maximum permissible limit set by the European Food Safety Authority, with the exception of arsenic, whose values in some samples slightly exceeded the set limit. For all samples, estimated health risk values for the elements quantified were higher in children than in adults. The hazard quotient for arsenic, hence, the hazard index for the elements, indicated a significant risk (&gt;1) for children for some of the honey samples studied. Arsenic was the major contributor to incremental lifetime cancer risk; its estimated value for children in all the honey samples exceeded the U.S. Environmental Protection Agency (EPA) threshold limit (&gt;1.0 × 10−4); hence, the total cancer risk values for the carcinogenic elements indicated an absolute unacceptable risk level for children based on EPA threshold limit.

The determination of Cd, Co, Cr, Cu, Fe, Na, Zn, and Pb by inductively coupled plasma-optical emission spectrometry (ICP OES) was performed on dry matter and decoctions of the medicinal plants Cordia salicifolia, Chiococca alba (L.) Hitchc., and Echites peltata used as an appetite suppressant and diuretic in Brazil. The accuracy of the measurements was analyzed by the spike recovery test. Results showed that the concentration of these seven metals (Cd, Co, Cr, Cu, Fe, Na, and Zn) in dry plant samples is below the oral concentration of elemental impurities established by the United States Pharmacopoeia Convention (USP). However, there are no concentration limits for Fe, Na, and Zn established by the USP in drug substances and excipients. Levels higher than the recommended value by the USP were observed for Pb and the lowest for Cd, Co, Cr, and Cu, both in dried plant samples and their decoctions. In the decoctions prepared from these plants were found elements such as Cd, Co, Cr, Cu, Fe, Na, Zn, and Pb. In the decoction prepared from 40 g C. salicifolia leaves and 40 g C. alba wood, the content of Cd is above the oral daily exposure value set by the USP. Hazard index (HI) for decoctions prepared from these plants exceeded the threshold (1). Given the uncertainties associated with the estimates of toxicity values and exposure factors, futures researches should address the possible toxicity in humans. Uncontrolled selling and long-term ingestion of medicinal plants can cause toxicity and interfere with the effect of drugs. Limited knowledge on the interaction potential of medicinal plants poses a challenge and public health problem in Brazil and other countries.
