Abstract

The concern that quarry activities threaten the sustainability of total environment in many developing countries is on the increase. To address this issue with affordable solution, Iyuku community of Auchi, Nigeria, has been investigated. Field study found micro to mega cracks on the wall of structures, often causing collapse. Abandoned pits turn pond, causing groundwater pollution, and breed disease vectors. Noise from rock blasting and other quarry operations are responsible for loss of biodiversity particularly birds. Soil samples were collected at depths 0-15 and 15-30 cm from the three quarry sites and from a control, 1 km off the quarry sites, against the direction of drainage. Water sample was also collected from an abandoned quarry pit turned pond. These samples were analyzed for heavy metals and physico-chemical properties. Atomic Absorption Spectrophometer (VGP 210 Bulk scientific) was used for heavy metal analysis and Flame photometer (M410 SHERWOOD) was used to measure sodium and potassium. All physico-chemical properties and heavy metals tested of the soil showed positive anomaly with the control (background values), confirming total degradation and unsustainable mining practice. Future study will focus on the chemistry and level of dust in ambient air, and how to minimize blasting vibrations and noise level in the area.
