AbstractToxic metal phytoextraction potential of some higher plants, the white mustard (Sinapis alba L.), perennial rye grass (Lolium perenne L.) and also two cultivated plants, as green pea (Pisum sativum L. var. Rajnai törpe), radish (Raphanus sativus L. var. Szentesi óriás vaj), was studied in a field experiment, along the river Danube in close vicinity of an industrial town, Dunaújváros, Hungary. Soil/sediment and the various plant organs (leaves, stems and roots) were assessed for the contamination with some potentially toxic elements (PTE), such as the cadmium (Cd), nickel (Ni), copper (Cu), and zinc (Zn). It was found that Cd and Ni concentration was below, while the Cu and Zn elements were above the Hungarian permissible limits in each of the studied soil/sediment samples. Bioconcentration factor (BAF) was less than 1 in the shoot biomass of test plant samples and followed the order of Cu > Zn > Cd and Ni. Phytoremediation potential of selected test plants was found to be rather limited. The translocation factor (TF) was more than 1 for Cu and Zn elements, at each test plants. Cadmium was translocated into the leaves in case of the radish, only. Considering of the potential human daily intake of metals (DIM), it was less than 1 both for the adults and for the children. Health risk index (HRI) values of children, however, were higher than 1 for the Cd in case of radish, and for Zn and Cu in case of the pea. Results suggest that consumption of these plants grown in gardens of contaminated sediments can result in some risks for citizens in the industrial town of Dunaújváros. Further studies are required to identify appropriate plants with greater toxic metal phytoextraction potential.

Objective. Street-vended foods offer numerous advantages to food security; nevertheless, the safety of street food should be considered. This study has investigated the level of potential toxic metal (Pb, Cd, Hg, Sb, Mn, and Al) contamination among street-vended foods in Benin City and Umunede. Methods. Twenty street food samples were purchased from vendors at bus stops. Metals were analyzed with atomic absorption spectrophotometry. The methods developed by the US EPA were employed to evaluate the potential health risk of toxic metals. Results. The concentrations of the toxic metals in mg/kg were in the range of Pb (0.014–1.37), Cd (0.00–0.00017), Hg (0.00–0.00014), Sb (0.00–0.021), Mn (0.00–0.012), and Al (0.00–0.22). All the toxic metals except Pb were below permissible limit set by WHO, EU, and USEPA. The daily intake, hazard quotient, and hazard index of all toxic metals except for Pb in some street foods were below the tolerable daily intake and threshold value of 1, indicating an insignificant health risk. Total cancer risk was within the priority risk level of 1.0E-04 but higher than the acceptable risk level of 1E-06. Conclusion. Consumption of some of these street foods is of public health concern.

The increasing pollution in most industrialized area is a really attention seeking issue now a days. Air pollution caused by vehicular smoke contains handsome percentages of heavy metals like cadmium. Cadmium like other heavy metals accumulated in the bodies of living systems found around roads. Among the living system cadmium accumulate up to alarming rate like in soil, plants and animals. Therefore, this study was conducted in order to evaluate the possible risk of the Cadmium on the soil, forage and buffalos. The study was done in the area of Sargodha district, Punjab, Pakistan. There were six sites selected for study on accumulation of Cd in the forages, soil and the Buffalo blood. The Cd content in soil samples was highest in sample collected from site III. The Cd content was highest in the forage sample collected from site IV and in the blood samples, and the bioaccumulation factor was highest in the samples collected from site V. The positive and non-significant correlation was found when soil and forage was correlated, unlike the correlation found between blood and forage which was found negative non-significant. The samples from site III showed high daily intake of metals, health risk index, and pollution load index. This study will bring attention towards the development of the strategies in order to be safe from the toxic effects of cadmium.

AbstractThe study aims to assess the trace metals and physicochemical properties of water in the adjacent to the Sylhet gas blowout area. Trace metals were analyzed using atomic absorption spectrophotometer, whereas physicochemical parameters were evaluated in-situ state using portable instruments and also in the laboratory. Trace metals Pb, Cd, and Ni were found in the water samples higher than the acceptable limit by WHO standards, whereas the concentration of Cu and Zn were within acceptable limit, respectively. The correlation coefficient matrix and factor loading analysis spectacle that the interrelationship among the physicochemical parameters, trace elements, as well as other ions are moderate to strongly corellated which reflecting the homogeneous source of origin. According to contamination factor, Nemerow multi-factor index, pollution load index, and also, potential ecological risk index, the water of the region is quite polluted in case of Pb, Cd, and Ni but unpolluted for Cu and Zn. The water quality index indicates that treatment of water is required before using it for domestic purposes. The health quotient and hazard index results are less than standard value 1 suggesting that there is no noncarcinogenic risk in the area. The carcinogenic analysis shows that the lifetime incremental cancer risk mean value of Cd and Ni are fairly insignificant and Pb is more significant for children to cause health problem. The ILCR value of Cd and Ni are insignificant whereas Pb is significant to pose health risk for adults. Physicochemical parameters revealed that the water was slightly acidic and soft in nature implying to avoid the water from this area for drinking purposes. At the end, it can be concluded that this study will be useful for the residence as well as the policymaker to take the protective surveillance measures around the areas.

Heavy metal concentration in sewage water irrigation of fodders, milk, and soil was studied. It was a serious issue because excess of sewage water is used for irrigating crops and due to excessive use of waste-water heavy metals build up in plants and when animals consume these plants metals transfer to their bodies and milk causes different problems. Six samples were collected Trifolium alexandrinum, Avena sativa, Zea mays, Pennisetum glaucum, Sorghum bicolor, Brassica campestris from five sites. All the samples were digested by wet digestion method. After digestion a clear transparent solution of all samples was obtained which was analyzed in atomic absorption spectrophotometer. Different indices were applied including bio concentration factor, daily intake of metals, health risk index, enrichment factor, pollution lad index, correlations of fodders, soil and milk was done. Pollution load index of current study was less than 1 which indicates that soil was less polluted. Health risk for Cd was present higher than 1 which was an indication of risk to health of animals in eating Cd contaminated fodders. Daily intake of metal was lower than 1 it showed there was no risk in consuming fodders to health of animals. In water samples level of Cd was higher above permissible limit. Cd mean concentration was higher in milk than permissible limit which showed that animals graze more contaminated fodder in open areas and drink waste-water that�s why metals accumulate in their tissues and milk causing toxicity.

The present study was carried out to assess heavy metals Cadmium (Cd), Lead (Pb), copper (Cu), zinc (Zn), Chromium (Cr) and Nickel (Ni) levels in vegetables like Cauliflower (Brassica oleracea var. botrytis), Cabbage (Brassica oleracea), Carrot (Daucus carota), Brinjal (Solanum melongena), Spinach (Spinacia oleracea) and Radish (Raphanus sativus) irrigated with domestic wastewater. The vegetable samples were randomly collected from the farmlands irrigated with domestic wastewater around the Hisar district. Spinach, cabbage, brinjal and carrot accumulated higher Cd (1.30±0.31 mg kg-1), Pb (4.23±0.32 mg kg-1), Cu (1.42±0.25 mg kg-1), Zn (3.4±0.28 mg kg-1), Cr (1.16±0.11 mg kg-1) and Ni (2.45±0.86 mg kg-1) respectively. Transfer Factor (TF) of Cd, Pb, Cu, Zn, Cr and Ni are more in spinach (0.0306), cabbage (0.4448), spinach (0.2642), cauliflower (0.2494), carrot (0.0764) and spinach (0.7469) respectively. The health risk assessment has been calculated followed by Estimated Daily Intake Metal (EDIM) and Estimated Health Risk Index (EHRI). The present study highlights that both adults and children consuming vegetables grown in wastewater irrigated soils accumulate significant amount of these metals. However, the values of these metals were lesser than recommended maximum tolerable levelsproposed by the FAO/WHO (1999).

Air pollution is very important issue now-a-days. This has affected the components of environment to a great extent. Organisms like animals, plants and human beings are forced to live in such polluted environments. One of the pollution sources to the environment is vehicular traffic which has toxic effect on the roadside plants. In this study, roadside forages, soil and buffalo blood were studied to estimate the level of heavy metal pollution, iron in particular, in Sargodha from six chosen sites at perimeter of major roads. Collected samples were processed and digested for quantification of iron by atomic absorption spectrophotometer. Soil and buffalo samples from the site V showed high concentration of iron, whereas in forage, samples collected from site IV had greatest iron concentration. The bio concentration factor found for forage-soil was highest in the samples collected from site IV. On the other hand, bio-concentration factor for blood-forage and pollution load index was found highest in the samples collected from site V. Correlation for soil-forage and blood-forage was found negatively non-significant. The daily intake of metals for iron was found highest for site IV. The Health risk index was highest for the samples collected from site VI.

Abstract Heavy metal pollution has thoroughly worldwide apprehensions due to the instantaneous growth of industries. Farming regions are irrigated mainly with wastewater which contains both municipal and industrial emancipations. Therefore, three sites irrigated with ground, canal and municipal-wastewater in the District Jhang were selected to determine the zinc accumulation and its transfer in the soil, plant and animal food-chain. Soil, forage and animal samples of cow, buffalo and sheep were selected from each site. Various pollution indices were also measured to assess the zinc exposure to grazing animals. Zinc concentration was ranged as 18.85-35.59mg/kg in the soil, 26.42-42.67 mg/kg in the forage and 0.982-2.85mg/kg in the animal samples. Investigated zinc concentration in soil and forages was found to be within the recommended WHO/FAO limits but blood samples exceeding the standards of NRC (2007). Maximum level of pollution load index (0.427-0.805mg/kg) and enrichment factor (0.373-0.894 mg/kg) for zinc was noticed upon waste water irrigation. Daily intake (0.039 to 0.082 mg/kg/day) and health risk index (0.130 to 0.275 mg/kg/day) of zinc metal was higher in the buffaloes that feed on waste water irrigated forages. Bio-concentration factor (0.840 to 2.01mg/kg) for soil-forage was >1 represented that these plants accumulated the zinc concentration into their tissues and raised health issues in grazing animals on consumption of waste water contaminated forages. Overall findings of this study, suggested that animal herds should be monitored periodically to devise preventive measures regarding the toxic level of heavy metals availability to livestock.

Water pollution is a major threat to public health worldwide. The health risks of ingesting trace elements in drinking water were assessed in the provinces of Punjab and Khyber Pakhtunkhwa, Pakistan. Eight trace elements were measured in drinking water, using Inductively Coupled Plasma Mass Spectrometry (ICP-MS), and compared with permissible limits established by the World Health Organization (WHO) and the Pakistan Environmental Protection Agency (Pak EPA). In addition, health risk indicators such as the chronic daily intake (CDI) and the health risk index (HRI) were calculated. Our results showed that the concentrations of chromium (Cr), nickel (Ni), and manganese (Mn) were 2593, 1306, and 695 ng/g, respectively, in Lahore and Jhang, while the concentrations of arsenic (As) in Lahore, Vehari, Multan, and Jhang were 51, 50.4, 24, and 22 ng/g, respectively, which were higher than the permissible limits suggested by the WHO. The values of CDI were found to be in the order of Cr > Ni > Mn > Cu > As > Pb > Co > Cd. Similarly, the health risk index (HRI) values exceeded the safe limits (>1) in many cities (eg, Cr and Ni in Lahore and As in Vehari, Jhang, Lahore, and Multan). The aforementioned analysis shows that consumption of trace element-contaminated water poses an emerging health danger to the populations of these localities. Furthermore, inter-metal correlation and principal component analysis (PCA) showed that both anthropogenic and geologic activities were primary sources of drinking water contamination in the investigated areas.

Abstract Objectives There is a growing public health concern on the indiscriminate use of pesticides in agriculture among farmers from developing countries including Nigeria. The presence of pesticide residues in food samples may pose a deleterious effect on food safety and consequently compromise the health of consumers especially children, elderly, and pregnant women. The estimation of pesticides residues via dietary intake constitutes a vital integral part of regulatory processes that seeks to preserve public health. This study is therefore focused on the estimation of some pesticide residues in samples of Irish potatoes collected from Jos Nigeria. Methods The samples were collected from five different markets in Jos Plateau State Nigeria. All the samples were transported to the Central Research Laboratory, Ilorin, Nigeria. The pesticide residue analysis was carried out using GC/MS after sample extraction, filtration and Concentration. After the analysis was carried out, the result obtained were subjected to statistical analysis using SPSS (Statistical Package for Social Sciences) statistical software (version 21) after which the Mean, Standard deviations and ANOVA (Analysis of variance) were calculated. Results The result shows that 17 different pesticide residues were identified with ten (10) organochlorines, two (2) organophosphates, one (1) thiocarbamate, one (1) benzamide and two (2) of them were unclassified. The concentration of these pesticides were determined which was then used to determine the estimated daily intake. The ADI and MRL for each pesticide was sought for and the health risk was also evaluated. With the results obtained, it was noticed that most of these pesticides usually exceed their ADI and MRL which then makes them hazardous to the human health. Considering the health risk index of consumers Aldrin, Heptachlor, Mecarbem and Dieldrin proved to be very hazardous (P &gt; 1). Conclusions These pesticides can cause harmful effects on the food commodities which ultimately cause a damaging impact on the health of human. To guarantee food safety, continuous monitoring is recommended for pesticide residues in Irish potatoes. Funding Sources Self-sponsored.
