Abstract The aim of this study was to assess the risk of human exposure to lead (Pb), cadmium (Cd), and mercury (Hg) through agricultural soil by considering both uncertainty and variability in key exposure parameters. For this reason we collected soil samples from 29 locations in the Tuzla Canton (Bosnia and Herzegovina) and measured their metal levels with inductively coupled plasma atomic emission or absorption spectrometry (ICP-AES and ICP-AAS, respectively). The levels of Pb ranged from 13.33 to 1692.33 mg/kg, of Cd from 0.05 to 3.67 mg/kg, and of Hg from 0.02 to 2.73 mg/kg. To estimate cancer and non-cancer risks we used deterministic and semi-probabilistic methods. Lead was found to involve higher health risk than the other two heavy metals. Its hazard index (HI) decreased between population groups (children>women>men) and exposure routes (ingestion>skin contact>inhalation). Our Monte Carlo simulations indicated that Pb HIs for both adult populations had a 0.6 % probability to exceed the threshold value of 1, while in children this probability was 14.2 %. Cd and Hg showed no probability to exceed the threshold in any scenario. Our simulation results raise concern about possible adverse health effects of heavy metals from soil, especially in children. It is very important to continue monitoring environmental pollution and assess human health risk, not only with respect to soil, but also with other important environmental compartments, such as air and water.

Indoor Dust

AbstractIndoor dust acts as a media for heavy metal deposition. Past studies have shown that heavy metal concentration in indoor dust is affected by local human activities and atmospheric transport can have harmful effects on human health. Additionally, children are more sensitive to heavy metals due to their hand-to-mouth behaviour and rapid body development. However, limited information on health risks were found in past dust studies as these studies aimed to identify heavy metal concentrations and sources of indoor dust. The objective of this review is to discuss heavy metal concentration and sources influencing its concentration in indoor dust. Accordingly, high lead (Pb) concentration (639.10 μg/g) has been reported in heavy traffic areas. In addition, this review paper aims to estimate the health risk to children from heavy metals in indoor dust via multiple exposure pathways using the health-risk assessment (HRA). Urban areas and industrial sites have revealed high heavy metal concentration in comparison to rural areas. Hazard index (HI) values found in arsenic (As), chromium (Cr) and Pb were 21.30, 1.10 and 2.40, respectively, indicate that non-carcinogenic elements are found in children. Furthermore, most of the past studies have found that carcinogenic risks for As, cadmium (Cd), Cr and Pb were below the acceptable total lifetime cancer risk (TLCR) range (1×10

AbstractThe study assessed the level of heavy metals in surface water across Ndawuse River near the dumpsite at Phase 1 District of the Federal Capital Territory (FCT), Abuja, Nigeria. The results indicated that oxygen demand, turbidity and heavy metals were above the standard limits set for drinking water. Multivariate analysis using principal component analysis and hierarchical cluster analysis revealed natural and anthropogenic activities as sources of heavy metal contamination. The estimated non-carcinogenic effects using hazard quotient toxicity potential, cumulative hazard index and daily human exposure dose of surface water through ingestion pathway were less than a unity. The estimated carcinogenic risks (CRing) exceeded the suggested potential risk limits, with lead (Pb) having the highest CRing value for all age groups. However, children were found to be more susceptible to heavy metals over a period of time according to the estimated values. The concentration of heavy metals in the investigated river could pose an adverse health risk to several communities that rely on this receiving water bodies for domestic purposes. Therefore, there is need for strict enforcement of environmental laws to protect aquatic ecosystem and to avoid long term cumulative exposure risk that heavy metals may pose on human health.

AbstractDue to urbanization and industrialization, there has been an increase in solid waste generation and has become a global concern and leakage of leachate from landfills contaminate the soil and groundwater and hence can have a severe impact on human health. The present study aimed to determine the composition of toxic metals (Cr, Mn, Cu, As) and heavy metals (Cd, Ba, Hg, Pb) in soil and water by an inductively coupled plasma optical emission spectrometer (ICP-OES). To ensure accuracy during the analysis of Cr, Mn, Cu, As, Cd, Ba, Hg, and Pb in real samples, certified reference material (CRM, SRM 2709a) of San Joaquin soil and water (SRM 1640a) were analyzed and results were presented in terms of % recovery studies. The mean concentration of all the metals in soil and water did not exceed the limit set by the European Community (EU), WHO, and US EPA except Cu where the permissible limit defined by the EU is 50–140 mg/kg in soil. The soil is uncontaminated to moderately contaminated with respect to all metals except the Cu and Pb. Among the average daily dose (ADD) of soil, ADDing and ADDinh for children had the maximum dose for all metals than adults while ADDderm was higher in adults. Hazard quotient (HQ) trend in both adults and children was found in order HQing > HQderm > HQinh of soil for all metals except Ba which followed HQing > HQinh > HQderm. Hazard index (HI) values of soil for Cr and Pb in children were 7 and 7.5 times higher than adults respectively. Lifetime cancer risk (LCR) value for Cr by different exposure pathways of soil was 5.361 × 10−4 for children which are at the lower borderline of risk for cancer.

Significant Difference

The levels of Fe, Zn, Mn, Cu, Pb, Cd and Hg in the edible tissues of Mytilus galloprovincialis Lamarck, 1819 (Mediterranean mussel) picked up from the Black Sea coasts of Turkey have been determined by Inductively Coupled Plasma – Mass Spectrometer (ICP/MS) with a view to biomonitoring metal contamination in 2015. In this work, a statistically significant difference in the amounts of all studied heavy metals analyzed was noticed amidst sampling areas namely Igneada, Sinop, Samsun and Trabzon so that appraise welfare threat for mussel consumers, utilization M. galloprovincialis as biomonitors. The outcomes of this study were contrasted with the outlines stated by the Ministry of Agriculture, Fisheries and Food (MAFF), the Turkish Food Codex and Commission Regulation (EC) for the harmless consumption restrictions of Bivalves as seafood. Moreover, former works with mussels in the Black Sea countries were reviewed and a summary of heavy metal amounts in mussels from whole the Black Sea waters were presented. In general these available measurements clearly indicated a low level heavy metal in M. galloprovincialis in coastal waters of the Black Sea. In this study the concentrations (mg metal kg-1 wet wt.) of metals ranged from 18-35 for Fe, 8-27 for Zn, 2.8-4.5 for Mn, 0.5-1.8 for Cu, 0.06-0.31 for Pb, 0.04-0.10 for Cd and 0.03-0.07 for Hg. Considering human health with respect to the investigated heavy metals, the estimated daily intakes (EDIs) did not exceed the permissible intakes. No chronic systemic risk was found since total hazard index (0.521) were quite below critical value 1, and the carcinogenic risk for heavy metals did not exceed the tolerable values. Although there was no health risk to consumed mussels from the Black Sea riparian countries, the amount of mussels consumed is mainly unknown in countries; thus, consumption of about 1 serving of mussels from clean coastal waters per week is enough.

Heavy metal contamination of agricultural soils can instigate risk to human health via oral ingestion, particle inhalation, and dermal contact. The study evaluates the concentrations, distribution, and human health risk of various heavy metals in soil samples from crude oil polluted agricultural soil of Ogoniland, Nigeria. Soil samples were collected and analyzed for cadmium, lead, chromium, copper, iron, manganese, zinc, arsenic and mercury using AAS (SensAA). Measured concentrations of these heavy metals were employed to calculate the health risk for children and adults using Hazard Index (HI). For the children and adult population, the HI value for oral ingestion to lead in the polluted site was greater than one (HI > 1), and hence non-carcinogenic effects is considered as significant for human health. It is therefore of the essence to consider taking risk management measures in order to reduce the risk of human health from lead.

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.

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.

Aims: Man-made activities such as excessive oil exploration, automobile emissions, gas flaring and agricultural activities tend to elevate the concentrations of heavy metals in the surrounding. Heavy metals have the tendency to accumulate in plant roots, which may result to heavy metal contamination. Objectives: This study aimed at evaluating the concentration of heavy metals such as Lead (Pb), Cadmium (Cd), Nickel and Zinc (Zn) in Pawpaw fruits, seeds, leaf and Scent leaf from Amosoma community in Bayelsa State, Nigeria. The concentrations of these metals were used to assess the human health risk melted to the consumers of the vegetables and fruits. Materials and Methods: Sixteen different vegetables and fruit samples comprising of Pawpaw and Scent leaves were digested and analyzed for heavy metals using Flame Atomic Absorption Spectrophotometer (F-AAS). Results: The result of the present study reviewed that Pb, Cd, Ni, and Zn ranged from 1.090 ± 0.01 - 5.990 ± 0.06; 0.213 ± 0.03 - 1.317 ± 0.02; 2.810 ± 0.04 - 4.767 ± 0.09; and 0.793 ± 0.01 -5.303 ± 0.02 mg/kg, respectively. The concentrations of Pb, Cd, and Ni in some of the analyzed pawpaw and scent leaf samples exceeded the permissible limit as recommended by WHO/FAO, EC/CODEX and NAFDAC respectively. The concentrations of Zn were below the permissible limit as recommended by WHO/FAO. The Estimated Daily Intake (EDI) of Pb and Cd exceeded the oral reference dose (RfDo) however; Ni and Zn fall within the oral RfDo. The Target Hazard Quotient (THQ) and Hazard Index (HI) values of Pb, Cd, Ni and Zn were less than 1. The Carcinogenic Risk (CR) of Cd and Ni exceeded the range of permissible predicted lifetime risks for carcinogens as recommended by US EPA, meanwhile, the carcinogenic risk of Pb was within the permissible predicted lifetime risks as recommended by USEPA. Conclusion: The result from the present study indicate that the fruits and leaves from pawpaw and scent leaf may be contaminated with Pb, Cd, and Ni and the exposed population may be at risk of developing cancer due to carcinogenic ingestion of Cd and Ni over time.

Abstract From the last month of 2020, sudden outbreak of novel corona virus caused socio-economic lockdown in many countries. Many studies proved that temporary shutdown of economic sectors helped to recover river water quality. Perhaps, for the first time, this present study is conducted in an industrially and agriculturally influenced catchment of river Damodar, India. This research was fixed some relevant objectives like (i) to evaluate the changes of heavy metals (Zn, Cd, Pb, Ni, Cr and Fe) and microbial contamination (TVC, TC and FC) of river water (ii) to identify the magnitude of human health hazard during lockdown compared to pre lockdown and unlock phase. Total 33 water samples were collected in three periods. During lockdown, TVC, TC and FC showed the gradual decreasing trend in this stretch. All samples exceed the concentration of microbes compared to recommended standard in three periods. Among all heavy metals, Zinc, iron, chromium found their abandoned presence in the river water. Heavy Metal Pollution Index (HPI) showed 100% sample water of highly polluted (HPI > 150) type for drinking and other purpose. During lockdown, HPI showed around 54.54% sample changed to lower pollution and 45.45% changed to medium pollution level. During unlock phase, 45.45% samples again changed to high pollution. Pearson’s correlation coefficient and hierarchical cluster analysis indicated strong relation among heavy metals with fecal coliform in this river. This suggests high possibilities of common source of contamination (wastes of iron and steel plant, chemical plant, cement factories, agricultural runoff, municipal sewages etc) in river bed. No carcinogenic Hazard Index (HI) values of ingestion by children indicated higher potentiality to health risk (HI > 1) in all samples of three periods and during lockdown, 36.36% samples showed no possible health risk for adults (HI < 1). HI of dermal contact showed no possible health risk for children and adults in three periods. This assessment strongly recommended scientific and cheep management techniques to control water pollution and related health hazard in the study area.

Corbicula fluminea serves as traditional food to the local people in Kelantan, Malaysia. Concerns regarding river contamination, smoking method, and associated adverse effects on public health had been increasing. Hence, this study aims to measure the level of heavy metals (Cd, Cu, Mn, Pb, and Zn) and assess human health risk in C. fluminea consumption at Kelantan. Heavy-metal analysis was done using flame atomic absorption spectrophotometry, while human health risk was assessed using provisional tolerable weekly intake (PTWI), target hazard quotient (THQ), and hazard index (HI). The estimated weekly intake (EWI) for all metals was found within PTWI, while THQ for Cd, Cu, Mn, Pb, and Zn was 0.12, 0.06, 0.04, 0.41, and 0.03, respectively. The HI was calculated at 0.61 which is less than 1, considered as the safe consumption level. Therefore, C. fluminea consumption in this study was found safe from the health risk of noncarcinogenic effect over a lifetime.
