Negative Impacts

One of the negative impacts of the landfill as solid waste disposal is soil contamination by heavy metals. This study assessed heavy metals impact, especially Pb, Cu, Zn, and Cd, in the soil in Piyungan landfill, Bantul, Yogyakarta, Indonesia. The assessment was conducted by analyzing 15 soil samples from 25 cm depth in the study area, which was divided into three-zone. The study results showed that generally, the highest content of metals was found in zone II, which is located near or directly situated in a landfill site. The pollution index (PI) calculated showed in order Cd>Cu>Pb>Zn. The result also indicates that Cd has the highest pollution index and even the highest risk compared to Pb, Cu, and Zn. The eco-risk index (RI) calculation showed that the value was 29 to 70 demonstrating a low class. The result also indicates that the accumulation of heavy metals investigated in this study was normal, and that the ecological risk was relatively low.

Absorption of heavy metals through swampy agricultural soils may have serious consequences on human health. Present study determined the levels of Chromium (Cr), Nickel (Ni), Copper (Cu), Zinc (Zn), Arsenic (As), Cadmium (Cd) and Lead (Pb) using X- Ray Spectrometry in 10 swampy agricultural soils. The result of this study revealed that, the heavy metals with their respective concentrations (Cr (278.1), Ni (462.1), Cu (314.1), Zn (502.8), As (13.5), Cd (524.5) and Pb (295.5)) were found in the soil samples in mg/kg. It also pointed out that the concentration of the heavy metals in the all soil samples for all locations in decreasing order was Cd > Zn >Ni > Cu >Pb > Cr >As. The concentration in swampy agricultural soils from Kokona was obviously higher than the safe limit set by the regulatory bodies which may be because of the geological activities in the studied area. Hence, heavy metals accumulation in swampy agricultural soils is a big concern in Kokona where people’s daily meal largely contains rice or rice based products which are mostly cultivated in swampy agricultural soils.

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.

Samples of surface (0–3 cm) bottom sediments of the Lithuanian aquatic area of the Curonian Lagoon and Nemunas River delta were taken from 41 sites in 2013 and 2014. Sediment parameters, such as the percentage of particles, concentration of organic carbon and heavy metals (Cu, Zn, Ni, Pb, Cr, Cd, and Hg), were determined. The heavy metal contamination of the surface layer of bottom sediments was determined using the Nemerov’s pollution index applied to soil. The spatial distribution of contamination indices and the dependence of contamination dynamics on sedimentation factors were analysed. It was determined that heavy metal concentrations had a tendency to increase as sediment particles became finer and as Corg concentration increased. A greater amount of pollutants got into the aquatic area of the Curonian Lagoon that was closer to the Klaipėda harbour than into other lagoon zones. The heavy metals for the integral pollution index for the Curonian Lagoon and Nemunas River delta surface bottom sediments could be arranged in the following order: Cd>Pb>Cu>Ni>Hg>Cr>Zn.

The current work accomplished a comprehensive evaluation of heavy metals pollution in soil of agricultural areas from Tanjaro sub-district, Sulaimaniyah province, Kurdistan Region, NE Iraq. Ninety soil samples were collected from thirty different locations. Concentrations of 16 heavy metals were measured by inductively coupled plasma optical emission spectrometry ICP-OES. The pollution index (PI), potential ecological risk index (Er), enrichment factor (EF), and ecological risk index (RI) were used to assess the pollution in soil samples. High levels of Li and Ni, and moderate Ba, Cd, Hg, and Pb according to the results of concentration analysis, pollution index (PI), and potential ecological risk (ERI). High levels of Cd and Hg according to the results of Er. Agglomerative hierarchical clustering (AHC) and principal component analysis (PCA) suggested that heavy metals were generated from different natural and anthropogenic sources like natural weathering, fertilizer application, and transportation. Origins of Hg, Cd, Ni, and Pb are probably from activities like overuse of pesticides and fertilizers, whereas Pb could be exhausted from vehicle exhausts as well. Furthermore, spatial distributions revealed nonpoint source pollution for the studied heavy metals. The obtained results help in the remediation techniques of contaminated soils such as dilution with decontaminated soil or extraction or separation of heavy metals.

The concentration of heavy metals (Cr, Cu, Ni, Zn, Mn and Fe) were studied around coal mine spoil piles in Shiguai district of Baotou located in Inner Mongolia grassland and desert transition zone. Aim of the study is to control soil heavy metal pollution of coal mining area and provide the basic data information. The results indicated that concentrations of Cu, Cr, Ni and Zn in the soil along the roadsides were higher than other sampling areas. The pollution characteristic and the elements of heavy metal contamination were corresponding with the concentrations of the different types of coal mine spoils. According to the single factor pollution index, soils from different regions were contaminated by Cr, Cu, Ni, Zn, Mn and Fe in varying degree. The pollution degree was in order: Cu > Cr > Fe > Zn > Ni > Mn. Nemerow’s synthetical pollution index indicated that soils from the roadsides had the most serious heavy metal contamination, the index was 3.11. The order of pollution level in different regions was: roadsides > flood land > farmland > woodland. The health and stabilization of environmental quality are being threatened by soil heavy metals.

Study Results

The study attempted to assess the impacts of the brick kilns emissions on the farm soil in and around the kiln areas. A total of 72 representative farm soil samples were collected from 12 selected brick kiln clusters in Rajshahi and Gazipur Districts of Bangladesh, covering two years (September 2015 to August 2017). The collected samples were analyzed using standard methods. The pH and organic matter content in the farm soil samples were found to be very low. The farm soil parameters such as pH, organic matter, and soil texture were found in critical conditions. Among all of the heavy metals, only Cr exceeded the permissible standard of some soil samples. The concentration of Cr ion varied from 9.50 to 52.77 and 16.54 to 70.13 ppm in Rajshahi and Gazipur Districts, respectively indicated the chance of metal contamination in plants. The study results showed that the values of contamination factor (Cif) and ecological risk factor (Eir) in the selected farm soil of Rajshahi and Gazipur Districts existed in the order of Cd > As > Cr > Pb > Zn and Cd > As > Pb > Cr > Zn, respectively. The study results also showed that the pollution load index and risk index values were lower than 1 and 150, respectively, at all sampling locations indicating lower pollution and risk from heavy metals in the areas. The study observed that continuous brick production over the periods degraded topsoil fertility and reduced agricultural productivity.

Agricultural soil should be periodically tested for the improvement of crops. Soil physicochemical properties indicates the soil nutrient content and characteristics. The physicochemical parameters and heavy metal contamination in different agricultural soils of Coimbatore were analyzed. Soil samples were collected at the depth of 15 cm from five agricultural field. Soil samples were analyzed for physicochemical parameters and heavy metal contamination in the laboratory using standard protocols. Different agricultural soil samples were analyzed for parameters like pH, electrical conductivity (EC), TDS and salinity. Macronutrients nitrogen, phosphorus and potassium were estimated. Micronutrients like sodium and potassium also estimated for all the samples. Heavy metals like nickel, cadmium, lead, zinc, copper and manganese were estimated to check contamination status. The results stated that, all the soil samples were acidic in nature. Paddy cultivated soil was slightly alkaline in nature. All the soil samples were non-saline. Micro and macro nutrients were present in optimum level in all the soil samples. Heavy metals were present within their threshold limit and permissible limit. The study concluded that soil physicochemical parameters and heavy metal concentrations varied in five agricultural soils. Soils are good in their physicochemical parameters. This study indicates the quality of agricultural soil and it is useful to farmers regarding the nutritional and contamination status.
