The concentration of six heavy metals such as Cu, Cr, Ni, Cd, Zn and Mn were studied in the soils around Perlis. The aim of the study is to assess the heavy metals contamination distribution due to industrialisation and agricultural activities. Soil samples were collected at depth of 0 – 15 cm in five stations around Perlis. The soil samples are subjected to soil extraction and the concentration of heavy metals was determined via ICP - OES. Overall concentrations of Cr, Cu, Zn, Ni, Cd and Mn in the soil samples ranged from 0.003 - 0.235 mg/L, 0.08 - 41.187 mg/L, 0.065 - 45.395 mg/L, 0.031 - 2.198 mg/L, 0.01 - 0.174 mg/L and 0.165 - 63.789 mg/L respectively. The concentration of heavy metals in the soil showed the following decreasing trend, Mn > Zn > Cu > Ni > Cr > Cd. From the result, the level of heavy metals in the soil near centralised Chuping industrial areas gives maximum value compared to other locations in Perlis. As a conclusion, increasing anthropogenic activities have influenced the environment, especially in increasing the pollution loading.

Anthropogenic activities are the major cause of environmental pollution. Industrialization, urbanization and agriculture activities are also causing huge troubles linked to human health in Pakistan. Heavy metals contamination has increased in drinking water because of urbanization and agricultural activities. Being one of the urbanized Cities, Dera Ghazi Khan has also been subjected to the hastily increasing harms of contamination. The respective study was planned to evaluate the heavy metals concentrations and identification of high risk areas for the inhabitants living in the city. Total ninety-six samples of drinking water were collected. TDS and EC were in the range of 1.48 to 8.412 mg/L and1.41 to 9.4µS/cm respectively. TSS was from 40 to 599 mg/L which were exceeding WHO guidelines in eight samples. Heavy metals such as Ni, Cr, Zn, Pb and Cd were measured through atomic absorption spectrophotometer. Zn average value was well within WHO standard while Pb was exceeded in thirty-nine samples. Cd was exceeded in fifteen samples; Cr and Ni were exceeded in eighteen samples. Sources of heavy metals identified as agricultural activities, domestic and commercial effluent. Ground water samples were found potable at some locations but at the same time pose serious threat to human health due to heavy metals above permissible limits.

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.

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).

Abstract The present study was conducted to assess heavy metals contamination in agricultural soils in the National Capital Region, Delhi. A total of 84 soil samples were collected from selected agricultural areas located near industries, national highways, state highways, Yamuna floodplain, residential complexes, and wastewater irrigated soils. Heavy metal concentrations (Al, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn), pH, and organic carbon (%) were analyzed in the collected soil samples. The average value of pH and organic carbon in the soil samples collected were 7.79±0.49 and 0.53±0.17 percent. Average concentrations of heavy metals in soils were found to be in the order of Fe> Al>Mn> Zn> Ni>Cr> Cu>Pb> Co> Cd with value as 14916.92 mg kg -1 , 13538.87 mg kg -1 , 277.16 mg kg -1 , 74.53 mg kg -1 , 35.34 mg kg -1 , 33.68 mg kg -1 , 22.94 mg kg -1 , 18.45 mg kg -1 , 1.88 mg kg -1 , and 0.92 mg kg -1 . A very high concentration of Fe (6640.09-32650.23 mg kg -1 ), Al (5631-27209.99 mg kg -1 ), Mn (73.8-735.72 mg kg -1 ), Zn (16.45-221.88 mg kg -1 ), Ni (7.63-192.63 mg kg -1 ), and Cr (9.65-127.21 mg kg -1 ) were recorded in agricultural soil samples. The average concentrations of Mn, Ni, and Zn in the soil samples were several times higher than their concentration in Indian natural background soils. A significant potential ecological risk has been noticed in nearly all the agricultural soil samples except for the samples collected nearby residential areas. The contamination factor has shown that most of the soil samples were moderately contaminated with Mn, Ni, Fe, and Cr and some soil samples were considerably to strongly contaminated with Cd, Zn, Pb, and Ni. Wastewater irrigated soils showed a moderate to a strong degree of accumulation of heavy metals (Cd, Ni, and Zn).

This research was carried out to evaluate the impact of dumpsite and farming methods (anthropogenic Activities) on wetland soil qualities. Soil samples were collected from three strategic locations in Irri and Uzere communities at Delta State of Nigeria, and a reference station (control) about 5 km away from the study site. The sampling was done at the end of the rainy season (September, 2020), when the flood water had started rescinding, at two soil depths (5 to 10 cm and 45 to 50 cm). The concentration of iron, nickel, copper and cadmium concentration of the soil samples were determined with the Atomic Absorption Spectrophotometer (AAS), according to procedures approved by ASTM International. Results obtained from the chemical analysis revealed irregular concentration and distribution of the heavy metals within the studied area. Regardless of the sampling depth, the highest heavy metal concentrations were observed around the active dumpsite. Ranking order of the heavy metals’ concentrations in all the sampling locations was Fe ˃ Cu ˃ Ni ˃ Cd. It was observed from the results that the profile concentrations of the heavy metals increased with an increase in the soil depth. Using the contamination factor to assess the heavy metals contamination of the wetland, the results showed that the area ranged from moderate to considerable level of contamination, while pollution load index reveled that wetland soils were moderately polluted with the heavy metals. In terms of the soil pollution, the overall results revealed that area closed to the wastes dumpsite (site 1) was heavy polluted with the heavy metals

Bottom sediment samples from six stations were sampled in pre monsoon 2016, from the Govindampalli – Durgarajupatnam (GP-DP) coast. Heavy metals viz., Fe, Mn, Cr, Cu, Ni, Pb, Zn and Cd analysis was carried out by using ICP-OES, and the average concentrations are as follows Fe > Mn > Zn > Cr > Pb > Ni > Cu > Cd. Various environmental indices like Factor Analysis (FA), Geo-accumulation Index (Igeo), Enrichment Factor (EF) and Pollution Load Index (PLI) were applied to the chemical data in order to know the levels of contamination and factors contributing to the pollution. Correlation coefficient results exhibits significant positive and negative relationships among Fe, Mn, Pb, Zn, Cd. All the environmental indices suggest that heavy metals were present at higher concentrations and the impacts of anthropogenic activities are crucial that serves as source of heavy metals in the zone. Relatively, maximum number of heavy metals viz., Fe, Ni and Pb were accumulated at the brackish environment i.e., at confluence of Swarnamukhi river (GP-S Station).

Heavy metals (HM) have been a global concern for its toxic and detrimental effect on the environment especially when it exceeds the permissible limit through anthropogenic activities like kaolin mining. Kaolin mining has improved the economic wellbeing of the local people through employment and otherwise; and at the same time attached with environmental consequences that threatens the livelihood of the community members. This study was carried out to ascertain the concentrations of selected heavy metals in kaolin mined soils and water body and its pollution density using single pollution indices such as contamination factor (CF), geo-accumulation (Igeo) and ecological risk factor (Er ). Soil sample were collected from three different kaolin mined sites labelled (A,B and C) also surface water samples were collected from upper and down streams of Iyi-ugbohoroAmaudara, both samples were digested and elemental analysis was carried out using Atomic Absorption Spectrophotometer (AAS UNICAM 919 model). The concentration of the metals in three different kaolin mined soil samples ranges from Pb(40.00, 52.00 and 55.09 mg/kg) Cr(45.01, 70.00 and 71.00 mg/kg) Ni( 32.10, 50.50 and 51.00 mg/kg) Cd( 2.16, 6.25 and 6.15 mg/kg) Co( 19.68, 57.06 and 56.00 mg/kg) Se(1.06, 0.50, and 1.00 mg/kg) Mn(0.001, 0.01 and 0.01 mg/kg) Hg( 2.01, 2.00 and 2.50 mg/kg) As( 1.07, 1.10 and 1.05 mg/kg) and Cu(33.01, 60.00 and 57.5 mg/kg). Results from single pollution indices used for the selected heavy metals from kaolin mined soil, samples (A,B and C) showed that Mn, As, Cr, Ni and Cu indicated low to moderate contamination factor while Cd, Se, Co and Hg indicated high to very high contamination factor in all the samples. The distribution trend of heavy metals concentrations in the upper and down streams of the river body during wet season, showed that there were significant difference between upper and down streams while dry season showed variations in significant differences between the upper and down streams of some of the heavy metals. The study therefore concludes that kaolin soils are contaminated with heavy metals as a result of kaolin deposit and its mining activities. The single pollution indices used for the study pointed out that Cd, Se, Co and Hg are very high in the kaolin soils. The surface waters of Iyi-ugbohoroAmaudara River at the study area are polluted with heavy metals as a result of kaolin mining activities in the area; more especially during wet season of the study. Consequently, these outcomes would pose a toxic effect to both fauna and flora and possibly threatens the aquatic lives and the local populace.
