This research report examines heavy metal contamination from a gold mining plant in Oman. Samples were collected from soils, stream waters, and crop plants near the mining site. The samples were analyzed for 13 heavy metals. Water from an acid evaporation pond showed high iron concentrations and trace amounts of other metals. Surface water samples exceeded WHO standards for several metals. Soil and plant samples near the gold pit contained elevated levels of manganese, aluminum, nickel, iron, and zinc. The mining and ore processing activities, which use cyanide leaching to extract gold, introduce heavy metals into the environment that can accumulate in the food chain and pose health risks to humans and other organisms.
