Abstract The effect of urbanization and industrialization in the urban city is soil contamination by heavy metals. This study was conducted to assess Pb, Cu, Zn, and Cd, in the soil of Yogyakarta city and its surrounding, Indonesia. The assessment was done by analyzing 45 surface soil samples in the study area, divided into three-zone. They are divided based on the distance of each zone to the center of the city. The zone III is located in the outermost of the study area, and zone I is inside the city. The results of the study showed that generally, the highest concentration of metals was located in zone I, which is located near or directly situated in a city center. The result indicated that Pb and Cd had the highest pollution index compared to Cu and Zn. The pollition load indeks (PLI) and geoaccumulation indeks (Igeo) calculations in the whole study area showed that the values demonstrated a moderate class in average. Special attention was needed to be given to the zone I, which has a higher PLI and Igeo index to reduce the source of emission for Pb and Cd.

The study assessed the concentration of heavy metals in three oil spill sites in Emohua local government area in Rivers State, Nigeria. Soil samples were collected at depth 0-30cm for surface soil samples and up to 10m for sub-surface soil samples depending on the depth of borehole. Groundwater samples were collected from drilled boreholes while the surface water samples were collected from fishponds or water bodies (rivers) close to the oil spill sites. The samples taken from the oil spill sites were analysed to determine the level of concentration of 10 Department of Petroleum Resource (DPR) specified heavy metals (Cd, Zn, Cu, Pb, Cr, Ba, Ni, Hg, As, and Co). BUCK Scientific Atomic Absorption Spectrophotometer (AAS) was used in detecting the concentration of the heavy metals. For the surface soil, Pb concentration in site A and B were significantly higher than what was obtained at site C, with a mean concentration of 219.70, 130.01 and 3.41mg/kg respectively for the three sites. The mean lead (Pb) concentration obtained in the surface soil was within DPR and United State Environmental Protection Agency (USEPA) acceptable limits. Barium also has significant concentration in both the surface soil and sub-surface soil. Kruskal Wallis test indicated significant difference in the Pb, Cd, Zn, Cu, Cr and Ba concentration in surface/topsoil among the three sites and also indicated significant difference in the concentrations of Pb, Cd, Cr, Ni, Ba and As in sub-surface soil among the sites. Little heavy metal concentration was found in both the groundwater and surface water. The study showed that even if some heavy metals were detected at the oil spill sites, they do not pose any serious health risk, as all the heavy metals in the four environmental media at the three sampling sites were below the national limit stipulated by the Department of Petroleum Resource (DPR), Nigeria.

Knowledge of variation in metal concentrations of playground soil in dry and rainy season could assist in controlling metal accumulation in children if playtime is regulated according to seasons. The present investigation was designed to find out the existence and trend of such variation. Thirty six surface soil samples from nine playgrounds of Owerri metropolis were collected during the dry season and rainy seasons of 2012 and 2013 and were digested in Pyrex glassware using nitric acid. Total heavy metal concentration was determined by AANALYST 400 Perkin Elmer absorption spectrophotometer and coefficient of variation was used to categorize variability. Results demonstrated significant seasonality for all five heavy metals with major variability observed between dry and the rainy season. Metal concentrations showed zinc as highest metal in both seasons whereas cobalt was lowest metal with Ni occasionally being lowest in the rainy season. The variation of metals concentrations in playground soil especially in the rainy season may add to the body burden of the children, and therefore reduced hours of play during this season is recommended.

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.

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.

Heavy Metals In Soils

<p>A method is proposed for the assessment of the interactive accumulation of heavy metals in soils. Sixty surface soil samples were collected from fifteen sites, at a depth of 0-30cm, evenly distributed, within the 30,700ha comprising the study area.</p> <p>It was found that at least&nbsp; some of these metals were significantly contributed to soil, i.e. Mn 9.53, Fe 8.06, Zn 0.86, Pb 0.29, Cd 0.033, Co 0.112 and Ni 0.125 kg/ha, respectively.</p> <p>Similarly considerable levels of plant nutrients were accumulated in the studied soil such as P<sub>2</sub>O<sub>5</sub> 8.6, or 3.75 kg P/ha, K<sub>2</sub>O 52.92 or 43.94 kg K/ha, and Ca 78.98 kg/ha. As expected, the heavy metals accumulated in lower concentrations than those of plant nutrients and in non toxic levels. Nevertheless, the toxicity of these metals must be considered in relation to long term accumulation.</p> <div> <p>It was shown that the proposed method, based on the quantification of the elemental interactions contribution in heavy metals, could be used as a tool for the quantitative assessment of their accumulation and for the prediction of the &laquo;silent&nbsp; pollution&raquo; that gradually occurs in soils with these metals.</p> </div> <p>&nbsp;</p>

In this study, the geochemical properties of heavy metal-contaminated soils from a Korean military shooting range were analyzed. The chemical behavior of heavy metals was determined by analyzing the soil pH, heavy metal concentration, mineral composition, and Pb isotopes. In total, 24 soil samples were collected from a Korean military shooting range. The soil samples consist of quartz, albite, microcline, muscovite/illite, kaolinite, chlorite, and calcite. Lead minerals, such as hydrocerussite and anglesite, which are indicative of a transformation into secondary mineral phases, were not observed. All soils were strongly contaminated with Pb with minor concentrations of Cu, Ni, Cd, and Zn. Arsenic was rarely detected. The obtained results are indicated that the soils from the shooting range are contaminated with heavy metals and have evidences of different degree of anthropogenic Pb sources. This study is crucial for the evaluation of heavy metal-contaminated soils in shooting ranges and their environmental effect as well as for the establishment of management strategies for the mitigation of environmental risks.
