It is also a highly vulnerable component of the environment. Over the past few decades, rapid industrialization and population growth have substantially increased the demand for freshwater (Med Crave, 2017). Access to safe drinking water is not only a fundamental human right but also vital for maintaining good health. In order to achieve optimal health and development, a continuous supply of safe drinking water is imperative for any country's population (Miner et al., 2016; Fatima et al., 2020). Unfortunately, a large part of the world's population does not have adequate access to safe water, and approximately 884 million people are faced with this problem. Over one third of this population lives in Sub-Saharan Africa (Kassie and Hayelom, 2017; Fatima and Kollegen, 2020). Physical, chemical, and biological parameters in the water and sediments typically determine surface and groundwater quality (Cherotich und Kollegen, 2023). These parameters show significant variation according to seasonal changes and the type of pollution (Kithiia, 2012;

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.

This study was carried out to compare the potentials of Aspergillus terreus, Bacillus species and Chlorella vulgaris in bioremediation and adsorption of reactive red 198 (RR198) dye used in fabric re-dyeing. This was achieved through inoculation of pure cultures of the organisms in the dye solution. The highest percentage adsorption for all the test organisms was recorded after 48 hours of inoculation, with Chlorella vulgaris displaying 86.4%, Bacillus species, 84.4% and Aspergillus terreus, 69.8% of dye adsorption. The results showed statistically significant difference in dye adsorption among the three species with Chlorella vulgaris having the highest adsorption potential compared to the Bacillus species and Aspergillus terreus. The adsorption process fitted with the Freundlich's isotherm, revealing a multilayer adsor...

The mean concentration of heavy metals in the surface soils (0-15 cm) indicated that Zn (0.10 mg/ kg), Pb (1.03, mg/kg), Cd (0.007 mg/kg), Cr (0.15 mg/kg) and Ni (0.17 mg/kg) while the mean value of heavy metals in the sub surface soils (15-30) were Zn (0. 11 mg/ kg), Pb (0.26mg/kg), Cd (0.008 mg/kg), Cr (0.15 mg/kg) and Ni (0.17 mg/kg). The mean concentrations of the five studied heavy metals (Zn, Pb, Cd, Cr and Ni) were below WHO (2007) and DPR (2002) standard. Results of heavy metal spatial variability showed that concentration of Zn and Pb in soils were significantly different (P < 0.05) between the dumpsites and for Cd, Cr and Ni concentration in soils were not significantly different (P> 0.05) among the dumpsites. Pearson's correlation coefficient showed moderate positive and significant associations between Zn and Cd (r = 0.580, P <0.05) while negative and significant association existed between Pb and Ni (r =-0.314, P <0.01). Based on recommendation, there is need of the ministry of Health and Sanitation Agency like Refuse management and Sanitation Agency (REMASAB) and NESREA to come up with health education programmes for the general population on the dangers of illegal growing of dumpsites around Zone settlement in the cities of Kano Metropolis.

Soils samples were collected from the soil at the depths of 0-15cm and 15-30cm representing top and sub-soils respectively and also from control site 100m away from the point of impact. Soil samples were taken to the laboratory for analysis of heavy metals such as Cd, Cr, Pb and Mn using Atomic Absorption Spectrophotometer (AAS) technique. The heavy metal levels had the mean values of (mgkg-1) 1.49 mg/kg for Cd, 2.453 for Pb, 1.890 for Mn and 0.108 for Cr. The result of single pollution index indicated that soil in the vicinity of asbestos factory was practically un polluted with Mn, Cr but slightly polluted with cadmium. Pearson's correlation showed positive and significant associations between Cd and Mn (r = 0.87, p<0.05), Pb and Mn (r = 0.490, p<0.05) while negative and significant association existed between Pb and Cr (r =-0.689*, p<0.05). The result indicates that heavy metals such as Pb, Mn and Cr were in the class of unpolluted while Cd at asbestos factory were found at level of heavy polluted grading classification.

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.
