Pollution of natural environment due to release of heavy metals from various sources is a widespread problem throughout the world. This study explains the effect of heavy metal contaminants in Roadside soil of Morena district. Twelve air dried surface soil samples were collected from 50cm – 1m (point A) and twelve from 30m (point B) away from the roadside along a road with a distance of 50 km. Heavy metals were found in both points with highest concentration at 50cm – 1m (point A). Roadside soil is a definite indicator of vehicular pollution from where the high degree of contamination, is expected. The presence of heavy metals like Cu, Cr, Fe, Pb, Zn and Mn in the roadside soil was also considerable.

Monitoring and assessment of heavy metal concentrations in shallot fields are needed to evaluate the potential risk of contamination due to heavy metals. This study aims to define the status of heavy metal contamination in shallot fields using contamination indices. A total of 184 soil samples (0-20 cm) were taken from shallot fields in Brebes Regency, Central Java. The soil samples were analyzed for the concentration of five heavy metals (Cd, Pb, Ni, Cr, and Co) with HNO3 and HClO4 extracts and measured using AAS. Assessment of the status of heavy metals contamination in the soil using contaminant factor (CF), geo-accumulation index (I-geo), and pollution load index (PLI). The mean concentration in shallot fields showed the following order Cr > Ni > Pb > Co > Cd and the concentration were still below critical limit values. Four metals are Pb, Cr, Co, and Ni are low contamination (CF<1), while Cd is considerable until very high contamination factor. Based on I-geo values, shallot fields are practically uncontaminated of Pb, Co, Ni, and Cr (I-geo<1), meanwhile the status of Cd is uncontaminated to moderately contaminated (0<I-geo<1). Generally, the shallot fields in Brebes Regency, Central Java is unpolluted with five metals (PLI<1).

Heavy Metal Concentrations

Venezuelan oil exploration and exploitation activities have been taking place since the 18th century. These long-term activities are closely related to heavy metal contamination because of the increasing input of toxic pollutants. Variations in heavy metal concentrations can cause, among other things, changes in metal distribution patterns, alterations in biogeochemical cycles, and increments in environmental and biological risks. The need for a complete baseline on heavy metal concentrations along the Venezuelan coast is critical. For this reason, we present the concentrations, distribution, and degree of contamination of 9 heavy metals (barium, mercury, copper, nickel, chromium, cadmium, zinc, lead, and vanadium) in marine sediments along the Venezuelan coast. We used the enrichment factor, the geoaccumulation index, and the mean effects range median quotients to evaluate the degree of contamination, comparing areas with and without intervention. Our results indicate that higher concentrations of these heavy metals are associated with places with greater anthropic activity, especially on the central and eastern coasts of Venezuela. Only cadmium showed extremely severe enrichment and a high degree of contamination. The biohazard potential was between 12% and 30% and was primarily associated with locations having high oil activity, which suggests that these places must be monitored, given the potential hazard they represent. This work encompasses the distribution and concentration of 9 heavy metals along the Venezuelan coast and takes relevance as a baseline for heavy metal concentrations and pollution indicators in marine sediments for Venezuela and the Caribbean.

The paper presents data on the content of gross and mobile forms of zinc, cadmium, lead and copper in the soils of Chita and its surroundings. The paper contains a comparative analysis of the accumulation (Kn) and movement (KP) coefficients of these microelements in organs ( Potentilla tanacetifolia Willd. ex Schlecht.), relative to their gross content and mobile forms in soils. The authors have revealed that soil samples of the studied sites contain unequal gross amount of heavy metals. In some points (6 and 3) the content of cadmium and zinc exceeded the Mac, that is why such soils have been attributed to heavily polluted. The index of biological activity on mobile forms of heavy metals in all sites significantly exceeded the same index on gross forms. It was found that Potentilla tanacetifolia are accumulators of heavy metal ions. Aboveground bodies accumulate and absorb cadmium and copper especially intensively, thus the content of mobile forms of these metals in the soil is insignificant. Excessive adsorption of trace elements in the phytomass of plants can be connected with surface contamination. According to the content of zinc and lead, the accumulation values in the organs of P. tanacetifolia were characterized by small coefficient values, against the background of their high concentration in the soil.

Aim: The study evaluated the heavy metals and contamination status of soil around active and abandoned waste dumpsites in Port Harcourt Metropolis, Nigeria. Methodology: Five soil samples were collected at the topsoil (0-15cm depth) in a regular distance of 20m, 40m, 60m, 80m and 100m from the center of the dumpsites and control plot. The soil samples were analysed for heavy metals (Cu, Cr, Cd, Fe, Pb and Zn), pH and total Organic C (TOC) using standard laboratory analyses and contamination indices to determine the soil contamination status. Descriptive statistics involving mean and standard deviation were used for the data analysis. Results: The mean concentrations of Cu, Cr, Cd, Fe, Pb and Zn in active dumpsite was 3.2616mg/kg, 0.3983 mg/kg, 0.2027 mg/kg, 6.5785 mg/kg, 2.6991mg/kg and 12.4111mg/kg respectively while that of the abandoned dumpsite are 1.3913mg/kg, 0.3693mg/kg, 0.0882mg/kg, 3.6235mg/kg, 0.4158mg/kg and 4.0140mg/kg respectively. Hence, the soil samples in both dumpsites exceeded the allowable limit of World Health Organisation (WHO). The order of heavy metal concentrations in the dumpsites was Zn>Fe>Cu>Pb>Cr>Cd. The contamination factor of the heavy metals follows order: Pb > Cu > Cr > Zn > Fe for both dumpsites. The degree of contamination ranged from (1612.51 to 2286.83 for active dumpsite and 26.14 to 641.46 for abandoned dumpsite) indicating very high degree of contamination. Modified degree of contamination ranged from 46.09 to 381.14 for active dumpsite indicating “ultra-high degree of contamination” and 4.36 to 106.91 for abandoned dumpsite indicating high degree of contamination to ultra-high degree of contamination. Pollution Load Index ranged from (5.08 to 8.12 for active and 1.63 to 4.16 for abandoned dumpsite) indicating polluted soil with various heavy metals.   Conclusion: the concentration of heavy metals combined with the contamination indices revealed that the soils around the dumpsites are contaminated/polluted; hence, pose ecological and health-related risk.

The study involves evaluation of quality of groundwater and soil near the Thermal power plant located in Udupi District, Karnataka, India based on seasonal variation. 24 samples of ground water and soil were collected during Pre-Monsoon, Post- Monsoon and Monsoon Seasons from the places which are surrounding the Thermal Power plant. Collected Ground water samples were tested for detection of various heavy metal concentrations such as Ni, Fe, Mn, Cr, and Pb and soil samples were detected for Ni, Fe, Mn, Cr, Pb, Cd and Co. Collected soil samples were sieved according to different Standard sieve size. After sieving, soil samples were digested using tri-acids (Nitric Acid, Hydrogen peroxide and Concentrated Hydrochloric acid). Both Ground water and Soil samples were analysed for heavy metal contamination by using Atomic Absorptive Spectrometry. From the results obtained for Pre-Monsoon, Post-Monsoon and Monsoon Season it showed that concentration of heavy metals in the samples were exceeding the permissible limit prescribed by WHO and BIS. Hence preliminary treatment should be done before discharging in to Ash ponds.

Sequential extraction or chemical fractionation of heavy metals allows inferences to be made about their origin, occurrence, bioavailability, toxic potential and environmental contamination. Thus, the present study aimed to assess the distribution of Cu, Mn, Ni, Pb and Zn among the different soil fractions and landscape compartments of a yellow latosol cultivated with vegetables. Soil samples were collected from five areas cultivated with tomato (Lycopersicon esculentum, Mill.), lettuce (Lactuca sativa), chili pepper (Capsicum annuum L.) and chard (Beta vulgaris L.) in different slope positions (upper, middle, lower), and four reference areas (native forest), at a depth of 0.00 - 0.20 m. Heavy metal levels were also assessed in water used to irrigate the crops and for human consumption by collecting 200 ml of water samples from reservoirs. The soil samples were sequentially fractionated to quantify the concentrations of adsorbed Cu, Mn, Ni, Pb and Zn in the exchangeable (EF), organic matter (OF), amorphous and crystalline iron oxide fractions (AFeOx and CFeOx). Landscape position only interfered significantly in heavy metal adsorption in the soil for Cu and Ni associated with CFeOx and Zn bound to the EF in the farming areas. The highest Cu, Ni, Pb and Zn levels were found in the fractions with less stable chemical bonds (bound to organic matter), in addition to a strong affinity between Cu, Zn and Mn and the oxide fractions (AFeOx + CFeOx). The low affinity of Pb and Ni for the AFeOx and CFeOx fractions indicates greater contamination potential for the water reservoirs. In the short term, organic matter is the main source of remediation for heavy metal contamination in soil, making it important to adopt conservation practices aimed at reducing OM losses.

<div> <p>This paper present migration of some selected heavy metal (zinc, lead, copper, chromium and nickel) of roadside soil samples from along Ilesa-Akure highway with a view to assess the degree of contamination such soils contain and the likelihood that this contamination can be remobilized. Soil samples were collected from 5 locations (Ilesa, Ipetu-ijesa, JABU, Ilara-mokin and FUTA north gate) at depths of 0-5, 15-20, 35-40 and 55-60cm and analysed for the five selected heavy metals in the bulk sample and clay fraction. Their concentrations and distributions in four different road verge zones (5m, 30m, 60m and 110m) were determined. The 5m zone had the highest mean concentration of the five metals whereas the 110m zone exhibited the lowest mean concentration. Zinc and lead exhibited a significant decrease in the roadside soils with the increasing distance from the road while chromium and nickel showed significant increase, copper on the other hand showed no significant difference. Quantitative assessment of the heavy metal contamination using the I<sub>geo </sub>and <em>PI</em> indexes showed that the selected heavy metals were in the order of Cu &lt; Pb &lt; Zn &lt; Ni &lt;Cr for both Indexes. Soil characteristics (which include pH, Cation exchange capacity {CEC}, organic matter and other basic geotechnical tests) responsible for the mobility and vertical distributions of these heavy metals from the road side soil were also assessed.</p> </div> <p>&nbsp;</p>

Background: Heavy metals like chromium compounds can be carcinogenic usually used in the tanning process during leather production. Chromium is an important health risk factor for the tannery workers which may enter the body by inhalation, ingestion and by direct cutaneous contact and cause several health problems of skin and respiratory tract. With the increase of unplanned industries, Bangladesh poses a new challenge to combat health hazards associated with heavy metal toxicity in soil.Objective: The present study was designed to find out possible toxic effects of heavy metals in soil and health hazards among the people residing at tannery industries area.Materials and Methods: This is a descriptive cross-sectional study and was carried out in two phases during the period of 1st November 2009 to 30 June 2010. In first phase the soil samples were taken from lagoons of Hazaribagh Thana of Dhaka city for laboratory test of heavy metals. In second phase, a total 190 respondents were interviewed using a semi-structured questionnaire to ascertain the common health problem around the tannery industries.Results: All the eight soil samples contained Cr, Mn, Ni, Fe, Pb, Cu, where as Cd was nil. Mean distributor of Cr, Mn, Ni, Fe, Pb and Cu was 43.1325, 354.2217, 28.6633, 22420.1867, 97.5833 and 53.4633 ppm respectively. 75.26% respondents stayed in the study area for six to ten years. Most of the respondents (75) were tannery workers. Total 52.85% households had toxicity related sickness in last six months. Among tannery workers most prevalent sickness were conjunctivitis (7.7%) and Dermatitis (6.7%). Regarding occurrence of clinical manifestations similar to Chromium toxicity in relation to staying in the study area, most of the households complained about allergy (39.2%) and abdominal discomfort (24.4%).Conclusion: Elevated levels of urinary and blood Chromium is associated with high morbidity among the tannery workers. Therefore bio-monitoring of the heavy metals in the exposed workers is considered as a useful tool.Anwer Khan Modern Medical College Journal Vol. 9, No. 1: Jan 2018, P 39-43

Heavy metals (including As, Cd, Pb, Ti, V, Cr, Mn, Ni, Cu and Zn) concentration analysis for soil samples from Westhill (near Huoshaogou) and source assessment of heavy metals in sludge from Huoshaogou wetland park in Xining city (China) have been carried out. Results show that Cd, Pb, Cr and Zn concentrations in the surface soil are much higher than that in the unpolluted soil from Westhill, and Cr concentration in the sludge from Huoshaogou wetland reaches 12 times and 6 times more than that in the unpolluted and in the surface soils from Westhill, respectively. The results reveal that descent of dust contributed Cd, Pb, Cr and Zn to the wetland, and wastewater mainly contributed Cr to the wetland. In order to protect the environment, human activities and heavy metal discharge should be limited effectively.
