Six locations, which are Wellington Industrial Estate Area 1 (WIEA 1), (WIEA 2), (WIEA 3), (WIEA 4), (WIEA 5), (WIEA 6), were used to collect samples with the aid of scoop and gravel free auger (at varying depths of 0 - 5 cm and 5 - 10 cm);the samples were given laboratory treatment. The Hesse model and Walkley Black technique were used in the determination of moisture content and organic carbon content respectively in samples collected. The results indicated that organic matter content in most of the soil samples collected are high which implies samples have high levels of metal deposition (heavy metals) and can be hazardous to the environment because of their toxic effect;it is also indicative of high level of microbial activities, these activities can also release nutrients to the environment.展开更多
