Industrial activity is one of the significant sources of environmental contamination with heavy metals, especially in developing countries. Flood can also lead to the distribution of toxic substances into the environment, regarding the Thailand flood in 2011 as some industrial estates are affected, leading to concern about heavy metals from industrial wastewater contamination. We aimed to measure the levels of Cd, Cr, Cu, Ni, Mn, Pb, and Zn in river and stream water, sediment, and fish collected from the area around the industrial estates in Uthai District and Bangpa-in District of Phra Nakhon Si Ayutthaya Province, following the floods of 2011. The results revealed that heavy metal levels in water did not exceed Thailand surface water quality standards, except for Mn levels at one sampling site. Metal levels in sediment and fish samples also did not exceed published standards. The hazard quotient for fish consumption was highest for Ni (0.2178) in Trichopodus trichopterus collected from the area near the industrial estate in Bangpa-in District, while the hazard index from Cd, Cr, and Cu exposure were 0.86966, which was lower than 1, indicating that the health risks for these seven metals were within acceptable ranges.

Fish is a major source of food in many parts of the world because they contribute to solving the global food problem and provide the well-known proteins, minerals, vitamin and trace elements content. Concentrations of iron (Fe), zinc (Zn), copper (Cu), nickel (Ni), lead (Pb) and cadmium (Cd) were determined in various parts of the fish (liver, gill, bone and muscle) of Mackerel (Scomber scombrus), Sardine (Sardinella longiceps), Hake (Merluccius merluccius) and Express (Platax scalaris) which were purchased from two major markets in Abeokuta, Ogun State, Nigeria. Heavy metal levels in the fish samples were analyzed by Atomic Absorption Spectrophotometer (AAS Buck 211). Health risks related to Fe, Zn, Cu, Ni, Pb and Cd were assessed based on target hazard quotient (THQ). Results obtained showed variations in the levels of heavy metals across the various tissues in the fish samples. The concentration of Fe was highest in all the tissues in the fish samples with the gill recording the highest level. There were higher concentrations of heavy metals in the gills than in other tissues of the fish samples. The trend of heavy metal levels in the tissues was found to be Fe > Zn > Cu > Ni > Pb > Cd. Highest levels of Pb and Cd in the muscle were 1.92 ± 0.04 and 0.64 ± 0.04 mg/kg in Merlucciusmerloccius and Scomberscombrus respectively. The concentrations of Pb and Cd were higher in the muscles of all the samples than European Community and Food and Agriculture Organization maximum permissible levels. The health risks from Ni and Pb were found highest among all the heavy metals in the fish samples. THQ values of Cu and Cd in Sardinellalongiceps and Cu in Merlucciusmerloccius were higher than 1. Health risk assessment of Ni and Pb in all the fish studied and Cd in Sardinellalongiceps indicates that their consumption may be unsafe.

Keban Dam Lake is the second largest dam lake in Turkey. In addition, it has the feature of being one of the most important dam lakes in our country in terms of both aquaculture potential and electricity generation. In this study, fish samples belong to Capoeta trutta caught from Örencik region of Keban Dam Lake were used. The concentrations of some heavy metals (copper, iron, zinc, chromium, nickel, cadmium, arsenic and mercury) in muscle of Capoeta trutta and the potential health risk from consumption of this fish species were examined. In addidion, the relationship between the heavy metal levels and some biological aspects of fish (weight, length and sex) were determined. As a result of the study, it was determined that the most and the least accumulated heavy metals in the muscle tissue of Capoeta trutta were zinc and cadmium respectively. The concentration of heavy metals showed differences according to weight, length and sex of fish. The results were found indicated that heavy metal levels in the muscle tissue of Capoeta trutta are below the tolerable values recommended by EPA, WHO and FAO. Therefore, there is not any risk for human consumption of this fish species.

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

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.

Background: Fish is a source of nutrition; however, toxic substances and heavy metals may enter human body due to consuming contaminated fish. The aim of this study was to investigate the levels of heavy metals and DDTs in Liza parsia, a fish species, and assess the health risk of the contaminants in the fish samples. Methods: The extracted fish lipid was added with n-hexane and H2SO4 and was kept for long time. The upper organic part was collected for the analysis of DDTs by gas chromatography equipped with electron capture detector. The fish samples were homogenized by wet digestion method, and the heavy metal contents were analyzed, using an atomic absorption spectrophotometer. The health risks of the fish samples were assessed based on target hazard quotient and target cancer risk. Results: The pesticide contents of DDT, DDD, DDE and DDTs in the fish samples were 0.0414, 0.000253, 0.015 and 0.0567ng/g, respectively. Also, the mean concentrations of Mn, Fe, Cu and Zn were 35.42±10.05, 318.75±242.45, 41.67±4.78 and 281.25±5.42 mg/kg, respectively. Of note, the Cd and Pb contents were below the detection limits. The concentrations of other heavy metals were above the reference limits, which can cause various disease processes. Conclusion: The contents of four heavy metals and DDTs in the samples were above the limits. The main sources of these substances are likely due to human anthropogenic activities. Fish and other edible aquatic animals should be monitored regularly and the heavy metal levels be determined and declared to the public.

Estuaries worldwide have been severely degraded and become reservoirs for many types of pollutants, such as heavy metals. This study investigated the levels of Cd, Cu, Mn, Ni, Pb, and Zn in water and whole fish. We sampled 40 juvenile silversides Odontesthes regia and 41 juvenile puye Galaxias maculatus from the Valdivia River estuary, adjacent to the urban area in southern South America (Chile). Samples were analyzed using a flame atomic absorption spectrophotometer. In water samples, metals except Zn were mostly below the detection limits and all metals were below the maximum levels established by local guidelines in this estuary. In whole fish samples, concentrations of Cu, Zn, Pb, Mn, and Cd were significantly higher in puyes than in silversides. Additionally, Zn, Pb, and Mn were correlated to body length and weight in puyes, whereas Cd was correlated to body length in silversides. The mean concentration of heavy metals in silverside and puyes were higher than those reported in the literature. In silversides, all heavy metal levels were below the limits permitted by current legislation (FAO), whereas in puyes Pb and Cd levels were above the recommended maximum level established by international guidelines, therefore putting the human population at risk.

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 pollution and its resultant accumulation to toxic levels in the Barekese reservoir may threaten human health through the consumption of fish from the Reservoir. The presence and concentrations of arsenic and some other heavy metals (Hg, Pb, Ni, Cr, and Cd) were determined in muscle tissues of widely distributed and highly consumed fish species from the Barekese reservoir using Atomic Absorption Spectrophotometry. A total of 45 fish samples comprising three species (Oreochromis niloticus, Tilapia zilli and Heterotis niloticus) were analyzed for their metal levels. Heavy metals concentrations (mg/kg, w.w) showed varying trends of detection among muscle tissues of selected fish species. However, Hg, Ni, Cr and Cd were detected in muscle tissues of all fish species examined in the study. Indices for non-carcinogenic and carcinogenic risks were estimated for child and adult upon their consumption of fish from the Reservoir. Results of the study indicate a significant level of exposure to Hg, Ni, Cr and Cd through the consumption of fish species from the Reservoir. Health risk assessment also revealed that children are at a relatively higher non-carcinogenic risk through the consumption of metals in Heterotis niloticus (HQ = 2.95 × 10-1). Also, the consumption of all examined fish species from the Reservoir pose no significant cancer risk effects to humans. The present study, therefore, concludes that anthropogenic activities along the Offin River and within the Barekese reservoir’s catchments could lead to deteriorating the quality of fish from the Reservoir hence regular monitoring of such activities is needed.

This study was conducted to estimate the concentration of selected heavy metals such as chromium (Cr), manganese (Mn), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), cadmium (Cd), and lead (Pb) as well as the possible risk to consumer health from the flesh of three wild and cultured fishes (Labeo rohita, Mystus cavasius, and Heteropneustes fossilis) collected from the Meghna river, Narayangonj and Rajoir fish farm, Madaripur district respectively. Heavy metal concentrations were determined using Atomic Absorption Spectrometric method. The average concentration of heavy metals were found in the wild fish samples in the range as Cr (0.295-1.647), Mn (0.900-1.294), Ni (0.063-0.198), Cu (0.179-0.529), Zn (5.487-8.343), Cd (0.004-0.009) and Pb (0.193-0.290) mg/kg dry weight while in the cultured fish samples in the range as Cr (0.043-0.315), Mn (0.975-2.36), Co (BDL), Ni (0.005-0.095), Cu (0.238-0.978), Zn (5.487-8.305), Cd (0.004-0.009), and Pb (0.238-0.286) mg/kg dry weight respectively. The hierarchy of mean concentration of heavy metals in wild fishes was Zn> Mn> Cu> Pb> Cr> Ni > Cd and in the cultured fishes, the order was found Zn> Mn> Cr> Pb> Cu> Ni > Cd. The present study showed that the wild fish accumulated higher concentration of heavy metals in their muscles than the cultured fish. The analyzed Ni, Cu, Zn, Cd, and Pb were below the allowable level specified by international agencies (FAO, WHO, EU, CE, USEP). In order to assess the human health risk, the Target Hazard Quotient (THQ), Hazard Index (HI), and Target carcinogenic Risk (TR) were calculated. The TR values suggested that the fishes posed low to moderate carcinogenic risk from Cr, Ni and Cd. Consequently, continuous and excessive consumption of these fish species over a lifetime will increase the possibility of causing cancer. Bangladesh J. Zool. 49 (2): 189-203, 2021

Heavy metals pollution of the environment is a serious concern because of the hazardous effects they pose to human health, ecosystems and other biological receptors. The aim of this study was to assess the ecological risk of exposure to heavy metals and physicochemical parameters around Otamiri and Imo rivers in Etche and Oyibo Local Government Areas of Rivers State. Water, sediment, arrow head plant (Sagittaria latifolia) and christmas bush Plant (Ceratopetalum gummiferum), tilapia fish samples (Oreochromis niloticus) and cat fish (Clarias gariepinus) were collected at different points from five sample stations for wet and dry seasons. These samples were analyzed quantitatively to assess the levels of contamination in the samples using the ecological risk assessment models associated with exposure to these contaminants. The results of the heavy metal analysis show that the Estimated Daily Intake (EDI) for biota samples ranged from 0.000 – 1.254 mg/kg/day while water ranged from 0.000 -0.322 mg/kg/day. The target hazard quotient (THQ) ranged from 0.000 – 69.228 for both biota and river water samples for Otamiri and Imo rivers The hazard index values indicated significant public health risk with values of 1.42 was recorded for Tilapia and 33.14 for Christmas bush plant. Cancer risk due to heavy metals exposure had a peak value of 1.04 x10-1 for wet season. The bioaccumulation of the metals showed that the pollution load index values ranged from 2.467- 5.822 in wet season and 9.708 – 99.853 in dry season. The presence of these heavy metals above threshold values suggest that the aquatic life that inhabit such rivers risk bioaccumulation which may affect the human population that depends on Otamiri/Imo rivers for fishing, drinking or irrigation. These poses a danger if bioaccumulation was to take place over a long period of time.
