Abstract
This study evaluates the environmental risks of quarrying activities in the Marksino Concession area, Akampka, with a focus on heavy metal contamination of the soil. Soil samples were collected at various distances from the quarry site and analyzed using atomic absorption spectrophotometry (FAAS; PG990) to determine concentrations of lead, chromium, copper, cadmium, cobalt, nickel, arsenic, and zinc. Pollution indices and ecological risk factors were calculated, along with hazard quotients and indices for non-carcinogenic impacts on children and adults. Results indicate that contamination values for all metals were below one, suggesting no significant impact at the sampling points. The geo-accumulation index values also indicated no significant impact for all metals. Furthermore, hazard quotient (HQ) and hazard index (HI) values for all metals were below the permissible value of 1, indicating non-carcinogenic risks for residents. However, children showed higher HI values compared to adults, emphasizing the need for targeted measures to protect this vulnerable group. Continuous monitoring and mitigation efforts are crucial for sustainable quarrying activities and prevention of environmental hazards in the Marksino Concession area.
