Evaluating the Contamination Degree and Risk Assessment of Heavy Metals Around Active Dumpsite Environment: A Case Study of Ozoro Community, Delta State, Nigeria

The use of lowlands for refuse collection point (dumpsite) is a very common practice in Nigeria. However, people cultivated the areas within vicinity dumpsites, without knowledge risk these heavy metals. Therefore, this study was done to evaluate metals pollution soils an active dumpsite. Four (4) soil samples (from 4 locations) at depth 0–20 cm were collected from (e.g. iron lead, nickel and cadmium) concentration analyzed according American Society Testing Materials (ASTM) International methods. Pollution indices (contamination factor, enrichment load index geoaccumulation index) used ascertain level contamination dumpsite area. Results obtained tests revealed that, area had high concentrations. concentrations ranged: 3420 mg kg-1 4323 kg-1, lead 28.92 58.84 2.89 6.91 cadmium 1.04 2.05 kg-1. ranked as Fe > Pb Ni Cd. results showed that highest values, which portrayed heavily contaminated with cadmium. correlation strong (r = 0.87) between nickel, indicating two got their source(s). will further help government environmental regulators plan carried out suitable remediation strategies, clean environment.
