Abstract The aim of study was access the cobalt and lead contamination in soil, forages and animals. Heavy metal pollution is a matter of prime significance in natural environment. Through food chain toxicity of heavy metals and their bioaccumulation potential are transferred into humans .Higher concentrations of metallic compounds are toxic to living organisms but these are essential to maintain body metabolism. Intake of food crops polluted with heavy metals is chief food chain channel for human exposure. Animals are exposed to heavy metal stress by the intake of richly contaminated food crops those are chief part of food chain. We collected samples of soil, plant, animal blood, hair and faeces to find contamination through wet digestion process in lab and metal analysis. Different forages were collected to study Zn amount in forages whilst soil and animals in Mianwali Pakistan. The health risk index (HRI) calculation was our major concern in this study. Our present findings also emphasized on the assessment of bio-concentration factor (BCF). We also calculated other significant indices i.e. Pollution load index (PLI), daily intake of metal (DIM), Health Risk Index (HRI) and Enrichment factor (EF). While the experimentation result showed different concentrations of metal in different seasons. When the Zn concentration in forages was (32.59-42.17mg/kg) and in soil (21.82-35.09 mg/kg). Soil samples showed higher level of (PLI) Pollution load index. Bio-concentration of zinc was (1.03-1.57mg/kg). It can be concluded as regular monitoring of the level metal is essential evaluate the contamination status.

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.

Seven varieties of sugarcane were grown on soil polluted with heavy metals, including Pb, Cd, and As. Sugarcane growth, the heavy metal contents in different sugarcane tissues, and the subcellular distributions of the heavy metals in the roots and leaves were analyzed. The purpose of this investigation was to study sugarcane growth tolerance, the accumulation of heavy metals and the mechanism of sugarcane tolerance to heavy metals at the subcellular level. Health risk assessments were performed according to the models recommended by the United States Environmental Protection Agency (US EPA). The patterns of heavy metal storage were demonstrated to differ among different tissues in all sugarcane varieties investigated. Most of the heavy metals that were absorbed accumulated in the roots of the sugarcane, and the heavy metals in the root cells were mostly located in the cell wall. The health risk index was used to analyze the juice and indicated that the consumption of sugarcane juice by adults and children posed no significant health risks. This study shows that sugarcane grown on heavy metal-contaminated farmland is safe for consumption. The results of this study revealed an important and positive implication regarding the cultivation of sugarcane on farmland that is polluted by heavy metals and the potential to simultaneously achieve sustainable economic output and potential environmental restoration.

Topsoils, mainly from crop fields, orchards, forests, and barns around the Pyeongchang River, were collected to investigate their heavy metal concentrations. Pollution load index, ecological risk index, and enrichment factor were applied to assess levels of heavy metal contamination for topsoils. The concentrations of cadmium (Cd) (1.7 mg/kg) and chromium (Cr) (4.1 mg/kg) exceeded the troublesome level in one site, whereas zinc (Zn) (396.7 to 711.1 mg/kg) and nickel (Ni) (40.1 to 95.3 mg/kg) in several topsoils exceeded the troublesome to countermeasure levels, according to soil contamination standards for the study areas. A significant risk of contamination was observed for mercury (Hg) by all indices, although the concentration in most of the topsoils was below the guideline. As expected, a positive linear correlation was observed for the values of pollution load index and ecological risk index, demonstrating lower heavy metal contamination in upstream areas compared to those downstream. High to extremely high ecological risk was observed in several samples for Zn and Ni, while all of the soils were unpolluted to slightly polluted, according to the pollution load index. A baseline study was not performed earlier for these sites, so these assessed values of heavy metals should be used as reference values for further assessment.

Abstract Soil heavy metal contaminated sites with multiple sources of pollution have caused worldwide public concern. However, the lack of correlation of risk assessment between source identification of heavy metal led to unclear direction of source governance. A methodology was established by combining source apportionment of human health risks with ecological enrichment to characterize source-identified risks of heavy metals based on Ordinary kriging interplotation. Principal component analysis (PCA) and positive matrix factorization (PMF) model were used to identify and classify potential sources of heavy metals synthetically. The integrated results were incorporated into the health risk model to evaluate potential non-carcinogenic and carcinogenic risk of soil heavy metals. A case study was conducted in Suzhou city of China. The results showed that concentrations of Cd and Hg were highly above the background values, accounting for percentages of 239.6% and 415.9% above background values, respectively. The source contributed human health risk index of As contributed 76.9% to non-carcinogenic risk by pollutant sources of agriculture activities. The Non-cancer health risk index for children and adults was 1.08 and 1.00 respectively. The cancer health risk was 3.67E-03 for children and 3.97E-04 for adults. Cr originated from indutriy activities, accounting for 29.5% of total heavy metals, and constituted the largest carcinogenic impact on the population. This study provided a new insight for the treatment of mutil-sources of soil heavy metal pollution and also some reference value for the improvement of the risk assessment system.

Contamination of the ecosystem is a highly concerning issue as various types of pollutants get released into the environment which ultimately enter the food chain and create disturbance there. This study reported the chromium concentrations in the buffalo blood, soil and forages. The heavy metals from the toxic smoke get accumulated in the forage and the buffalos consuming this contaminated forage. This study was carried out in Sargodha during December 2015 to January 2016 (winter) and May 2016 to June 2016 (summer). Five road sites (Mateela, Faisalabad roadside, Shaheenabad roadside, Bhalwal roadside and 50 chak were selected from sampling of forages, soil and buffalo blood sample. In order to find out chromium in the soil, forages and blood samples, the atomic absorption spectrophotometer was used. The values of chromium in soil and forage samples were found highest at Site-II, while the amount of chromium in buffalo blood samples was highest collected from Site- III. The bio-concentration factor for forage and soil was found highest at Site-III. The bio-concentration factor for blood and forage was highest at Site-VI. The correlation was found positive and significant when soil-forage was correlated. On the other hand, negative significant was found for chromium when blood-forage was correlated. The pollution load index, daily intake and health risk index was highest in the samples collected from Site-IV.

The intense mineral extraction in mining areas during the last several decades has produced a large amount of waste material and tailings, which release toxic elements to the environment. The aim of the study was to determine in two vertical profiles/sections (1 and 2) the heavy metal contents of samples derived from six samples, three from each section located in the porphyry copper mine Buchim area, Republic North Macedonia. The results have been compared to new Dutchlist (DL) and Kabata-Pendias (KP) standards and the following was concluded: As values ranged 14.985÷60.131 mg kg-1 with 4 samples above the target value of the DL (29 mg kg-1 As) and 6 above standard values given in KP value (5 mg kg-1 As), in that context Co values ranged 11 ÷57 mg kg-1 with 6 values above the target value of the DL (9 mg kg-1 Co) and 5 above standard values given in KP value (12 mg kg-1 Co), Cr with range 29.32÷75.76 mg kg-1 with 6 over KP value (10 mg kg-1 Cr) and none above the target value of the DL (100 mg kg-1 Cr), Cu with range 2694÷6749 mg kg-1 with 6 samples above the target value of the DL (36 mg kg-1 Cu) and 6 above standard values given in KP value (20 mg kg-1 Cu), Ni with range 59.57÷105.98 mg kg-1 with 6 samples above the target value of the DL (35 mg kg-1 Ni) and 6 above standard values given in KP value (20 mg kg-1 Ni), Pb with range 27.06 ÷96.08 mg kg-1 with 1 sample above the target value of the DL (85 mg kg-1Pb) and 6 above standard values given in KP value (25 mg kg-1Pb), Zn with range 147÷273 mg kg-1 with 6 over target value of the DL (140 mg kg-1 Zn) and 6 above standard KP value (64 mg kg-1 Zn), V with range 34.44÷92.57 mg kg-1 with 5 over target value of the DL (42 mg kg-1 V) and one above KP value (90 mg kg-1 V).In order to compare the level of contamination, the contamination factor (𝐶𝑓 𝑖 ), degree of contamination (Cd), and pollution load index (PLI) were computed. Serious numbers were found for Cu, as, Zn, Co and Ni, which exceeded standard values at almost all samples from both vertical sections. Compared from section 1 and section 2, pollution load index increased by 13.43%, which in almost all samples was classified as heavily polluted to extremely polluted. The fact that mining activities at the Buchim Mine last for almost 40 years, the presence of heavy metals in soils at a serious level is understandable. The high level of contamination is a result of heavy metal persistence and non-biodegradability.

Abstract In the present study, the effects of untreated wastewater and associated health risks were assessed in an abundantly consumed vegetable, Luffa cylindrica. In this direction, trace metal accumulations in L. cylindrica samples irrigated with three different water regimes (municipal wastewater, groundwater, and canal water) were determined. The metal levels were defined by atomic absorption spectrophotometer equipped with a graphite furnace and D2 corrector. Trace metal concentrations in L. cylindrica samples were in the range of 7.91–9.01, 3.78–4.22, 0.54–0.63, 39.18–43.27, 15.76–20.82, 29.04–42.49, 6.96–8.24, 5.85–7.72, 4.06–4.39 and 0.18–0.42 mg/kg for Mo, As, Se, Fe, Cu, Zn, Ni, Pb, Cd and Co, respectively. The health risk index values of As, Cd, Pb, Mo, Ni, Se and Co; and pollution load index values of As, Mo, Ni, Cu, Cd and Pb were high, indicating possible phytotoxicity. As had the highest value for the pollution load index suggesting high-risk levels. High levels of some metals could be an alarm call for consumers as the vegetable is irrigated with untreated wastewater.

In current work, we examined the absorption of metal Copper in generally grown food crops (Maize & Millet), cultivated in the waste water irrigated different Districts of Punjab, Pakistan. Analyzed samples of Water, Soil, shoot and grain were processed through atomic absorption spectrometric method. Our findings of Copper in water and Shoot were highest for Millet of Sargodha, irrigated with wastewater (1.69 mg/kg and 1.43 mg/kg respectively). In soil and grain samples maximum absorption of Cu was obtained in the waste water irrigated Maize (Sargodha) and Millet (Sheikhupura). Overall, Cu level was within the acceptable parameters set by FAO/WHO (2001). In this study, we also find out different indices such as Enrichment factor, Translocation factor, Pollution Load Index, Bio-concentration factor, Daily intake of metal and Health Risk Index. The study determined that frequently intake of waste watered forages in experimenting zone may carry possible health uncertainties in inhabitants.
