Seasonal Variations and Health Risk Assessments of Heavy Metals in Soils around Metal Scrap Recycling Industrial Areas of Ogijo, Ogun State, SW Nigeria | Chapter 5 | Novel Aspects on Chemistry and Biochemistry Vol. 5

 This division aimed to evaluate the levels of heavy metals in soils from ingot recycling conveniences that converts scrap materials into gird products in Ogijo, Ogun State, Nigeria. Shortage of iron mineral in Nigeria has led to the conception of metal reusing in urban centres and suburbs, place waste and scavenged metals are rolled to brace. This constitutes a bigger source of loud noises that contaminates the country's atmosphere. The soil samples were randomly composed in dry and wet seasons (5th to 7th March and 24th to 25th September 2020 respectively) inside the industries and societies in the vicinity of the scrap alloy recycling labors (SMRI). The physico-chemical characteristics of the soil revealed that the soils range from lightly acidic to somewhat alkaline, generally sandy and earth and of moderate fertility. The concentrations of the resolved heavy metals in the soils were establish to exceed the WHO legal limits of heavy metals. Pollution estimate models are indicators used to determine the presence and intensity of anthropogenic contaminator deposition on soils. In this study, the following contamination assessment models were working: Contamination Index (CI), Pollution Load Index (PLI), Contamination Degree (CD), Geo-accumulation Index (Igeo), environmental factors, risk index and Nemerow Index.Heavy metal advancement during two together dry and wet seasons ranged from practice rank (EF ≤ 1) to moderate enrichment. Eri principles ranged from depressed (Eri) <40) to moderate ecological risk (Eri > 80) accompanying all the risk indices of the locales low (RI < 150). The accruing non-carcinogenic, the energy index (HI) for ingestion and dermal for soil all along the dry season were all above 1 indicating non - malignant health concern for the citizens of the study areas as they written higher principles. The CRI was far above the acceptable limit displaying that residents in S3 all along wet season and S2 and S9 during the dry season have chance of contracting tumor through ingestion inside the life period of 70 years. Scrapyards  are  casually  sited  in  the districts  where  all  types  of  scraps  from  deserted automobiles,  machineries,  and  electrical  machines  are disassembled and recycled for further uses. Many of these scrap  fabrics  are  made  up  of  fabrics that  are toxic and  unfavorably  affect  the surroundings  after wrong management.  According to the contamination index data, the soil character in the study completely lessened as compared to the DPR culture. This suggests that the soil cannot be utilised for home or land purposes.
