This study was carried out to determine the possible heavy metal accumulation in fruits and leaves of Zivzik pomegranate (Punica granatum L.) grown in two different roadside orchards located in Pirinçli and Kapılı villages of Siirt province, Turkey. Leaf and fruit samples were collected from trees located at 0, 50, 100 m distances from the main roads. Plant samples were analyzed for cobalt (Co), nickel (Ni), cadmium (Cd), lead (Pb) and chromium (Cr) concentrations. The Co, Ni, Cd, Pb and Cr concentrations of fruit samples collected from Pirinçli village were ranged from 0.082 to 0.238 mg kg−1, from 1.160 to 1.559 mg kg−1, from 0.087 to 0.179 mg kg−1, 0.326 to 0.449 mg kg−1 and 0.606 to 1.054 mg kg−1, respectively. The Co, Ni, Cd, Pb and Cr concentrations of fruit samples from Kapılı village were between 0.085 and 0.137 mg kg−1, 1.042 and 1.123 mg kg−1, 0.037 and 0.076 mg kg−1, 0.277 and 0.520 mg kg−1 and 0.762 and 0.932 mg kg−1, respectively. Heavy metal concentrations of leaf samples from Pirinçli village varied from 0.191 to 0.227 mg Co kg−1, 2.201 to 3.547 mg Ni kg−1, 0.051 to 0.098 mg Cd kg−1, 0.535 to 0.749 mg Pb kg−1 and from 1.444 to 2.017 mg Cr kg−1. Similarly, the heavy metal concentration of leaf samples from Kapılı villages were between 0.213 and 0.217 mg Co kg−1, 2.160 and 2.511 mg Ni kg−1, 0.058 and 0.114 mg Cd kg−1, 0.579 and 0.676 mg Pb kg−1 and 1.688 and 1.518 mg Cr kg−1. The Co, Ni and Cr concentrations in fruit samples collected from 0, 50 and 100 meters to the main road in Pirinçli village were at statistically significant level, while only Ni concentration in leaf samples collected from 0, 50 and 100 meters to the main road was at significant level. In contrast, heavy metal concentrations in fruit and leaf samples collected from 0, 50 and 100 m to the main road in Kapılı village were not statistically significant level.

Abstract Heavy metal accumulation in vegetable tissues often poses a great risk for human health. In the present study, accumulation of heavy metal in green leafy vegetable crops of coriander, garden cress, lettuce and spinach were evaluated under waste water irrigation in fields located in Kahrizak, on the southern edge of the metropolitan city of Tehran, Iran. Atomic absorption spectrophotometery was used for determination of heavy metal concentrations in leaf tissue. The results showed that heavy metal concentrations in soil and irrigation water were significantly high than allowable levels. Analysis of plant leaf tissue showed that spinach and garden cress accumulated higher concentrations of heavy metals compared to coriander and lettuce plants. Central leaves of lettuce showed the lowest heavy metal concentration compared to outer leaves or leaves of other vegetable crops, and can be the safer product for fresh consumption. The results indicate that the vegetables produced in the region are not suitable for fresh consumption and the agricultural activities should change towards ornamental or industrial crops production.

Studies were conducted to determine: (a) the heavy metal concentrations in Halton Region agricultural soils; and (b) whether a 1984 estimate of at least 39 yr for practicing land application of sludge in the Region was valid. Soil samples were taken on a regular grid pattern from the agricultural area of the Region. In a very large proportion of the samples, heavy metal concentrations were less than the maximum permissible values for sludge application to land in Ontario and in most of the samples, they were less than or approximately equal to the mean values for uncontaminated soils in Ontario. In a small proportion of the samples, heavy metal concentrations exceeded the maximum permissible values for sludge application to land in Ontario. These samples were obtained mainly west of the Niagara Escarpment in the southwest corner of the Region and the offending metals were primarily Pb and Zn. High Pb and Zn concentrations in these soils were not related to sludge application but were naturally occurring and probably were derived from Pb and Zn sulfides in the soil parent material. It was concluded that sludge may be applied on a very large proportion of the agricultural land in Halton Region and that the 1984 estimate of at least 39 yr for continuing this practice was valid. Moreover, in view of recent reductions in annual sludge quantity for land application in the Region and in sludge Cd concentration, the 39-yr estimate was considered to be conservative.

Total heavy metal concentrations [cobalt (Co), chromium (Cr), copper(Cu), iron (Fe), mangnese (Mn), nickel (Ni), lead (Pb), and zinc (Zn)]were determined in surface soil samples from Port Macquarie, New South Wales,Australia. Composite topsoil samples (0–10 cm depth) had mean values(per kg) of 13 mg Co, 1020 mg Cr, 59 mg Cu, 136·7 g Fe, 719 mg Mn, 149mg Ni, 20 mg Pb, and 47 mg Zn. The topsoils were generally characterised by alow pH (3·8–5·2) and a mineralogy dominated by haematite,magnetite, quartz, and kaolinite. Chromium was predominantly present in thetopsoils as Cr3+ in microcrystalline chromite(FeCr2O4) and, to a lesser degree,in kaolinite and haematite. Differences in Cr soil concentrations with depthwere due to variations in the relative abundance of the various soilcomponents, rather than Cr3+ mobility within the soilprofile. The elevated heavy metal concentrations are the result of soildevelopment over metal-rich bedrock (serpentinite matrix melange) andassociated enrichment of relatively immobile elements (Cr, Fe, Ni) in theresidual soil profile. The ANZECC and NH&MRC (Australian and New ZealandEnvironment and Conservation Council and National Health & MedicalResearch Council) environmental investigation limits were exceeded for100% of the sample sites for Cr, 47% for Cu, 61% for Mn,and 58% for Ni.

The existence of these activities has an impact on the concentration of heavy metals in basic sediments in these waters. The purpose of this study was to determine the concentration of heavy metals in basic sediments and determine the correlation between the concentration of heavy metals with grain size on the base sediment in the liquid and the correlation between the concentration of heavy metals with organic matter. Analysis of heavy metal concentrations was carried out using the acid destruction method, then the concentration was read using the Atomic Absorption Spectrophotometer (AAS), and processed into a heavy metal concentration map using Arcgis 10.3. Based on these studies the value of heavy metal concentrations obtained in the range of 20.19 - 55.681 ppm. Heavy metal concentrations have a positive correlation with the mud and organic matter fractions with r values of 0.68 and 0.10, respectively. The distribution of heavy metals in this study is strongly associated with the fine grain size fraction and organic matter, through the adsorption process

Objective : The purpose of this study is to propose the concept of the human toxicity (human cancer and non-cancer) footprint (µg 1,4 DCB (Dichlorobenzene) eqv./m3) using heavy metal concentration data in the air in Provincial and Metropolitan City governments. In addition, the final goal is to assess and compare the human carcinogenic toxicity footprint in Provincial and Metropolitan City Governments from 1991 to 2019.Method : To calculate the human carcinogenic toxicity footprint using heavy metal concentration in Provincial and Metropolitan City Governments, the ReCiPe 2016 life cycle impact assessment method in life cycle assessment (LCA) was used. For the human carcinogenic toxicity footprint calculation, the heavy metal concentration data in Provincial and Metropolitan City Governments are multiplied by the characterization factors of each heavy metal such as Pb, Cd, Cr, Ni, and As (Cu, Mn, Fe, Al, Ca, and Mg are not included in the air monitoring data) data (µg/m3). The unit of human carcinogenic toxicity footprint is shown in µg 1,4 DCB eqv. value.Results and Discussion : The results show that the heavy metal concentrations in Provincial and Metropolitan City governments were decreased significantly from 1991 to 2019. In the case of Pb, Incheon was decreased by about 2,124% (from 0.427 µg/m3 to 0.0192 µg/m3), and Busan was decreased by about 1,250% (from 0.2471 µg/m3 to 0.0183 µg/m3). In addition, in Cd’s case, Gwangju decreased by about 1,550% (from 0.0033 µg/m3 to 0.0002 µg/m3), and Incheon was decreased by about 1,071% (from 0.0082 µg/m3 to 0.0007 µg/m3). The results of human carcinogenic toxicity footprint in 1991 (early stage), 2005 (middle-stage), and 2019 (current) show that the average of human carcinogenic toxicity footprint was 8,478 µg 1,4 DCB eqv. in 1991, 5,545 µg 1,4 DCB eqv. in 2005 (about 53% decreased from 1991), and 1,997 µg 1,4 DCB eqv. in 2019 (about 178% decreased from 2005). In 2019, the human carcinogenic toxicity footprint results showed that Gyeongbuk had the highest value of 5,184 µg 1,4 DCB eqv. followed by Busan 3,929 µg 1,4 DCB eqv., Gyeongi 3,305 µg 1,4 DCB eqv., Seoul 2,184 µg 1,4 DCB eqv., Gwangwon 2,011 µg 1,4 DCB eqv. One of the reasons for the highest human carcinogenic toxicity footprint is the concentration of Cr and As, which have very high characterization factors.Conclusions : In this study, the human carcinogenic toxicity footprint using a heavy metal concentration in Provincial and Metropolitan City governments was proposed and calculated. Even though the heavy metal concentrations were decreasing, the number of measuring stations should be increased in each Provincial and Metropolitan City Government to improve the data quality and reduce the human carcinogenic toxicity impact by heavy metals.
