In this study, the elemental analysis of soils and effluents collected from selected manufacturing industries in Kano metropolis of Nigeria West Africa for the wet season of 2020 has been carried out using standard analytical methods, Analar grade reagents and approved calibrated equipment. All samples were analyzed in triplicates and the outcome values are presented as mean concentration in mg/kg. The mean concentration of heavy metals evaluated such as Co, Cd, Cr, Zn, Mn, Fe, Ni and Pb show mixed levels (excessive, moderate and normal levels) when compared to the recommended levels by NESREA. Contamination factor (CF) and contamination degree (Cd) was determined for investigated elements in all 58 samples. CF for Ni, Pb, Fe, Mn and Zn were all ˂ 1, implying no potential ecological risk contamination. Enrichment factor (EF) was calculated to determine anthropogenic input of metals in all the samples investigated. High enrichment factor for samples MW, MS, ADS, FS, PPS, MW, DW, PPW, MyW, DFS, DS, AS, LZS, 7upW, and DFW (67.2 % of the samples), The mean concentration of the metals is an indication of pollution was tested with a high implication outcome most likely, when samples are continuously emptied into the environment untreated. Safe to remind us that heavy metals are toxic with excessive human health risks.

The state of art analysis of available published data allowed to determine the features of the roadside ecosystems formation and the possibility of further development of biodiversity conservation measures. In Ukraine and around the world, road infrastructure is an important economic and social object that has a negative impact on the environment. This takes place due to environmental pollution, fragmentation of habitats, biodiversity loss, etc. At the same time, on the roadsides the stations (microhabitats) are being formed. They can be a barrier to motor vehicle pollution and provide available shelters for living organisms. Road operation usually affects the structure of roadside vegetation. There is an increase in the number of of annual plant species and a decrease in perennials. Favourable conditions are also created for the spread of heliophytes and xerophytes. Roads are a source of chemical pollution that affects all components of roadside ecosystems. The amount of pollutants is mainly dependent on the traffic intensity and road width. The creation of roadside forest plantations significantly reduces the negative impact of vehicles. Wood plantations contribute to better carbon deposition, which is an integral part of many vehicle pollutants, and create a barrier for pollutants coming far from roads. Forest belt can also be a refuge for many species of animals and combine fragmented habitats around. Because plants and small animals at roadside stations are bound to their localities, they are able to accumulate much amount of ecotoxicants, especially heavy metals, which should be taken into account when conducting local business. For the living of animals in roadside stations, the characteristics of specific confined plant community, microclimate and landform are quite important. Due to the linearity and long distances, roadsides provide migration ways for many species. The developed roadside habitats may be the refugia for not only common, but for rare animals. We should conclude that further research of the environmental benefits of roadside ecosystems in the Steppe zone of Ukraine would allow developing effective measures for roadside management in the frames of nature conservation.

“…Indeed, the importance of trace elements in soil chemistry is becoming a global concern, particularly because soil is such an important component of both rural and urban environments. High levels of heavy metals in soils may not be due to anthropogenic effects, but rather to diagenetic causes 14 , 15 . Since metals from both natural and anthropogenic sources accumulate in soils, determining what fraction of the metal load comes from which source can be difficult.…”

The indiscriminate disposal of spent engine oils and other hazardous waste at auto mechanic workshops clusters in Nsukka, Enugu State, Nigeria is an environmental concern. This study examines the concentration of heavy metals in the soil inside the workshop cluster and in the unpolluted soil outside the workshop cluster at approximately 100 m. Ten sampling points were randomly selected from within the cluster and another ten from outside the cluster. Using a hand-held Global Positioning System, the coordinates of the selected points were established and used to create a digital map. Soil samples at depths of 0–30 cm and 30–60 cm, were analyzed for Cu, Fe, Zn, Pb, As and Cd using Spectrophotometer. Moisture content determination and particle size analysis were also done on the samples. Spatial variability of heavy metals concentrations of the studied site was also mapped with ArcGIS 10.2.2 using interpolation methods. Results showed that the soil ranged from sandy loam to sandy clay loam. Cadmium and Zinc had the lowest and highest concentration, respectively, in the studied area. Comparing the concentrations of heavy metals in soils within and outside the auto mechanic cluster revealed notable differences across various depths (0–30 cm and 30–60 cm). The analysis results for soil samples within the cluster exhibited concentration levels (mg/kg) ranging from 0.716–0.751 (Cu), 2.981–3.327 (Fe), 23.464–30.113 (Zn), 1.115–1.21 (Pb), 2.6–2.912 (As), and 0.133–0.365 (Cd) demonstrating a variation pattern in the order of Zn > Fe > As > Pb > Cu > Cd. Conversely, for soil samples outside the cluster, concentration levels (mg/kg) ranged from 0.611–0.618 (Cu), 2.233–2.516 (Fe), 12.841–15.736 (Zn), 0.887–0.903 (Pb), 1.669–1.911 (As), and 0.091–0.091 (Cd). To assess the disparity in heavy metal concentration levels between samples collected within and outside the clusters, ANOVA test was performed. The test showed significant difference in heavy metal concentrations between samples within and outside the auto mechanic cluster (p < 0.05), implying auto mechanic activities significantly impact heavy metal levels within the cluster compared to outside areas. The assessment of soil pollution utilized indices including the Geo-accumulation Index (Igeo), Contamination factor (Cf), and anthropogenic metal concentration (QoC). Zinc, Cadmium, and Arsenic showed the highest contamination factors, indicating significant soil contamination likely due to anthropogenic activities. The concentrations of the metals analyzed were within WHO permissible limits while the metals concentrations were also observed to decrease as depth was increased. Using ArcGIS 10.2.2, spatial maps showing heavy metal distribution were developed, with the Kriging method proving superior. This study suggests that heavy metal levels in the soil at the area be monitored on a regular basis.
