“…Soil contamination by heavy metals from waste disposal sites is a serious problem in industrial and urban areas (Mandal and Sengupta 2006). Soils are regarded as the ultimate sink for heavy metals discharged into the environment, as many heavy metals are bound to soils (Obiajunwa et al 2002). Furthermore, when screening for pollutants in soil and leachate at contaminated sites, the results are often required directly, since classification of the soil is needed before determination of remediation techniques (Banar et al 2007).…”

The concentration of heavy metals was studied in the soil samples collected around the municipal solid waste (MSW) open dumpsite, Ariyamangalam, Tiruchirappalli, Tamilnadu to understand the heavy metal contamination due to leachate migration from an open dumping site. The dump site receives approximately 400-470 tonnes of municipal solid waste. Solid waste characterization was carried out for the fresh and old municipal solid waste to know the basic composition of solid waste which is dumped in the dumping site. The heavy metal concentration in the municipal solid waste fine fraction and soil samples were analyzed. The heavy metal concentration in the collected soil sample was found in the following order:The presence of heavy metals in soil sample indicates that there is appreciable contamination of the soil by leachate migration from an open dumping site. However, these pollutants species will continuously migrated and attenuated through the soil strata and after certain period of time they might contaminate the groundwater system if there is no action to be taken to prevent this phenomenon.

“…These sites are poorly and most often never investigated to know the extent of petroleum hydrocarbon contamination and as a result there is high possibility of accumulation of these pollutants in the food chain by their consumption in drinking water, fish and crops, which could pose a risk to human and other terrestrial and aquatic life [6][7][8]. Crude oil pollution from spills and poor waste disposal affect the physicochemical properties of soils with sometimes also the build-up of high concentrations of heavy metals in the affected sites [9]. Overall, the sources of livelihood in impacted areas which include farmlands, rivers and forests have been negatively affected [10].…”

Co-contamination by petrochemicals and heavy metals emanating from refinery operations was investigated from sludge, soil and water samples immediately around WRPC refinery, Delta State, Nigeria. Collection and assessment of environmental samples from 5 different points across the refinery and groundwater for which the pH, Electrical Conductivity, Temperature, Turbidity, TDS, TSS, Total hardness, Alkalinity, DO, BOD, Cl¯, PO 4 3¯ and bacteriological analysis were measured. The total petroleum hydrocarbon and polycyclic aromatic hydrocarbon concentrations were 755.291 and 22.746 mg L -1 in the water samples, 8756.148 and 311.569 mg kg -1 for the soil samples, 65346.8 and 4190.598 mg kg -1 for the sludge samples via GC-MS analysis. The effects of the release of the industrial effluents caused the increase in pH, 5.2-5.3 across the studied samples. Conductivity measurements for the sludge, soil and water samples gave readings of 0.27, 0.25 and 0.48 µs cm -1 respectively. The presence and distribution of different heavy metals varied whereby the presence of cadmium (0.139 mg/l), cobalt (0.34 mg/l) and nickel (0.606 mg/l) in the water samples were above the WHO permissible limits. The highest concentrations of iron (108.77 mg/kg) and zinc (11.072 mg/kg) where observed in the soil samples while chromium (24.25 mg/kg), lead (3.902 mg/kg), mercury (0.21 mg/kg), arsenic (0.417 mg/kg), copper (2.015 mg/kg) and manganese (82.695 mg/kg) where highest in the sludge samples. Total bacterial enumeration revealed a count of 7.29 x 10 3 (cfu/g), 1.84 x 10 3 (cfu/g) and 1.32 x 10 3 (cfu/ml) in the soil, sludge and water samples respectively. The presence and concentrations of these mixed pollutants via the activities of the refinery resulted in change of known physicochemical properties which in turn affects the vegetative and microbial flora within the area.

Environmental pollution due to discharges of heavy metal containing sludge from textile industries is a common nuisance in Bangladesh, where no treatment of sludge is carried out before final disposals. Energy Dispersive X-ray Fluorescence (EDXRF) was employed in the present study to analyze the heavy metal content of Electrocoagulated Metal Hydroxide Sludge (EMHS) collected from a composite textile industry. Thirteen heavy metals, viz., Mn, Ti, Cu, Zn, Ni, Sr, V, Cr, Zr, Hg, Cd, Nb and Ga, were detected. Mn, Ni, Cu, Zn and Cd exceeded the permissible limit to apply the EMHS in agricultural land. Cr, Ni, Cu and Zn were compared to the values of the European legislation to evaluate the environmental risk and to classify the wastes as inert wastes or as wastes that have to be control landfilled. EMHS was categorized as class I and needs to be deposited in controlled landfills.
