Environmental Pollution of the Soil by Heavy Metals at a Dumpsite Located at Esuk Utan, Calabar, CRS, Nigeria

The rate at which heavy metals are polluting the soil at a dumpsite and at the residential area at Esuk Utan, Calabar Municipal Government Area was investigated. This was carried out by the method of digestion using UV visible Hach 500DC spectrophotometer. Analysis of the soil samples was done for ten heavy metals. The result showed that eight of the heavy metals analyzed for had values below the World Health Organization (WHO) limit for their presence in the soil and therefore were not harmful to the environment as at the time that the samples were collected. Iron and chromium however were present at levels greater than the minimum values recommended by the WHO. These two metals were found to be present at levels that could be dangerous to human health. Some of these heavy metals can find themselves into our food chain if we eat vegetables and other crops grown in and around the dumpsite. These heavy metals have very serious health implications if allowed into our body.

Mujahid Ajah Matazu, 2021

The study aimed to assess the level of metals contamination around municipal solid waste dumpsites in Kano metropolis, Nigeria. Forty-two soil samples were collected from seven municipal solid waste dumpsites (Durumin Zungura, Murtala Muhammad Specialist Hospital, Sharada, Kaura Goje, Tudun wada, Dorayi and Gwale). Analysis for the concentration of these heavy metals; Zn, Pb, Cd, Cr and Ni was conducted by the use of Flame atomic absorption spectrophotometer (FAAS).The mean concentration of heavy metals in the soils sample were Zn (0.009 mg/kg), Pb (1.02 mg/kg), Cd (0.007 mg/kg), Cr (0.15 mg/kg) and Ni (0.15 mg/kg) for surface soils (0-15cm) while the mean values for sub-surface soils (15-30cm) were Zn (0.10 mg/kg), Pb (0.27 mg/kg), Cd(0.008 mg/kg), Cr (0.15 mg/kg) and Ni (0.17 mg/kg). The maximum concentrations of the five heavy metals in both sample and control sites were below WHO (2007) and DPR (2002) standard. Based on the result of soil contamination around the dumpsites in Kano metropolis, it indicated that, all the seven dumpsites were in the class of low contamination. The contamination/Pollution Index values of all the studied heavy metals (Zn, Pb, Cr, Cd and Ni) were in the class of slightly contaminated by heavy metals. It is recommended that the government should consider a basement treatment for dumpsites before use. This will provide sorption surfaces for pollutant and prevent groundwater contamination.

Assessment of Heavy Metal Concentration in the Soil of Ugwuaji Solid Waste Dump Environs, Enugu Nigeria

2020

Solid waste is a major environmental threat globally, and Nigeria is not an exception. The problem of improper disposal of solid waste is further compounded by population growth and economic development, which leads to the generation of an enormous amount of solid waste. The resultant effects are environmental pollution with various pollutants such as toxic heavy metals. This research determined the heavy metal concentration in the soil of Ugwuaji solid waste dump environs in Enugu, Nigeria. The oil samples were collected and transported to the laboratory for analysis. The soil samples were analyzed for heavy metal using Atomic absorption spectrophotometer (AAS). The study concludes that poor waste management and accumulation of tons of solid waste in the dumpsite negatively affects the soil quality in the area. Further, the open solid waste dumping exposed the soil to serious contamination with heavy metals (Cd, Pb, Cu, Zn, and Fe). This implies to serious human and animal health d...

The soil samples were airdried, ground, sieved, digested and subjected to heavy metal analysis using atomic absorption spectroscopy. The analyzed metal profiles in the dumpsite soil samples are as follows:

Determination of Physicochemical and Some Heavy Metal of Soil around Dana Steel Industry Limited Katsina, Katsina State, Nigeria

The aim of this study was to investigate the physicochemical parameters and level of some Heavy metal concentrations in dumpsites soil around Dana steel limited dumpsite located in latitude 12º 57¹ 43¹¹N to 12º 58¹ 7¹¹N, Longitude 7º 37¹11¹¹E to 7º 37¹ 16¹¹E and altitude 522.5m to 616.6m in Katsina state of Nigeria were investigated in this research. Soil samples were collected from the dumpsite and control site at depths ranges 0-<10cm, 10-<20cm, 20-<30cm and 30-<40cm. The result of physicochemical parameters within the samples A, B, C,D and the control shows that there is a significant difference between contaminated and control soil. This is a clear indication of low moisture and organic matter content observed in the entire sampling site. For the heavy metals contents, Atomic Absorption spectroscopy (AAS) was used to obtain the composition and concentration of the six studied heavy metals (Zn, Cu, Cr, Co, Ni, and Pb). The Result obtained in this research showed that Pb had the highest concentration with the ranged average of 16.464-11.741mg/kg and Fe which has the lowest concentration with 0.219-0.379mg/kg. Statistical significant difference was observed between the mean of toxic metal concentration in the dumpsite and control area which suggested the effect of anthropogenic inputs, Therefore, the results indicated that the area under investigation was polluted with Cr, Fe and Cu withrespect to heavy metals content in contaminated soil and low Fe content with respect to the control soil. Somemetals content investigated were above the US EPAstandard of heavy metals in soils that requires cleanup

Mujahid Ajah Matazu and MZ Karkarna, 2021

The research was conducted to assess the level of heavy metals contamination using single and integrated pollution indices in soils around municipal solid waste dumpsites of Kano Metropolis, Kano State, Nigeria. Forty two soil samples were collected from seven municipal solid waste dumpsites of Kano metropolis using circular plot method. A stainless hand auger at a depth of (0 to 15) top soils and sub-surface soils (15-30cm) depth were collected and analyzed with Flame atomic absorption spectrophotometer to determine the heavy metal concentration. The mean concentration (mg/kg) of heavy metals from the depth of (15-30 cm) were observed to follow a decreasing order Pb (7.71)>Zn (0.50) > Ni (0.45) > Cr (0.31) > Cd (0.025) while for surface soils (0-15cm) the mean concentration were in the following order: Pb (1.77) > Ni (0.49) > Zn (0.30) > Cr (0.27) > Cd (0.012).The results showed that calculated CF and Er recorded that investigated soil samples are uncontaminated with Zn, Pb, Cd, Cr and Pb and Ni. The pollution load index (PLI) was less than unity showing that there was minimum pollution in the studied dumpsite. The potential ecological risk showed that soil samples were in the class of low contaminated with the studied heavy metals. The results showed that concentrations of heavy metals of soil samples from dumpsites location at waste dumpsites of Kano Metropolis were within limits of European Union (2002) standards.

International Journal of Research in Chemical, Metallurgical and Civil Engineering

Soil samples collected from the dumpsite located in Kuyi village, Minna, Niger State were analyzed for copper (Cu), iron (Fe 2+) and manganese (Mn) using Atomic Absorption Spectrometer. Twenty-one (21) sample points both horizontally and vertically (depth) were studied. The results revealed that Mn had the highest concentration (11.6mg/kg) compared to Cu and Fe 2+. However, it was observed that a minimal reduction in concentration of each metal along the surface of the dumpsite occurred. Interestingly, the concentration of Fe at all points was relatively high (5.54mg/kg, 4.67mg/kg, 3.99mg/kg and 3.78mg/kg). Based on the Federal Environmental Protection Agency and Land Disposal Restriction Standard Regulation, this metal could have adverse effect on human health, stream and agricultural activities of villagers around the dumpsite.

Assessment of Heavy Metal Contamination on Soil around E-Waste Dumpsite in Onitsha, Nigeria

Environmental Review, Volume 9, No 1., 2023

Electronic waste (e-waste) has become an issue of major importance as production technology rapidly develops and changes, and more unknown components of the waste enter the municipal waste stream. The absence of a structured management system and laxity in environmental laws and regulations in Anambra State have led to an increased influx of e-waste into the state. It has created an avenue for uncontrolled and crude methods of recovering valuable metals from waste. These ewastes are dismantled, some are burnt without prior knowledge of their composition and noxious matters are released into the environment. This study aimed to establish an understanding of the extent of heavy metals contamination on the soil around e-waste dumpsite in Ochanja in Onitsha, Anambra State with a view to generating baseline data on the extent of contamination of heavy metals from e-waste. Experimental research design was adopted and primary data were obtained through the collection of four different soil samples at varying distances within Ochanja e-waste dumpsite , the study Area. The collected soil samples were analyzed using Atomic Absorption SpectrophotometerAAS(GBC932AA) for the following heavy metals; Lead(Pb), Cadmium(Cd) Hexavalent chromium(Cr),Copper(Cu), Aluminium(Al) and Nickel(Ni). The result of the analysis showed that Al and Cr had maximium average value of 393.65mg/kg and 161.70mg/kg,followed by Pb(111.4mg/kg),Cu(102.37mg/kg),Cd(11.79mg/kg) and Ni(6.43mg/kg).The heavy metal concentrations in the soil were generally above 100mg/kg with exception of Cadmium (11.79mg/kg) and Nickel(6.43mg/kg),while the average concentrations of Al,Cu and Cd are above USEPA standard of 300mg/kg,50mg/kg and 3mg/kg respectively. The significant heavy metals found in soil samples in and around the dumpsites in the study area likely resulted from poor management of e-waste in the dumpsite in the study area. This is an indicator that the negative health impact of these heavy metals should be further investigated to avert any health and environmental consequences in the study area.
