Abstract– Various types of heavy metals are introduced into the soil by wastes produced as a result of opencast coal mining. Around the world, problems with metal toxicity and contamination are growing more prevalent. The plants only require a little amount of a few elements as nutrients, but if they are present in large quantities, they can be poisonous to the plants. In this investigation, soil samples were taken and tested for a number of common toxic heavy metals, including Cu, Cd, Cr, Fe, Hg, As, Pb, and Sn, from the coal overburden dump area and a nearby agriculture site, both located 5 kilometres apart. Through the use of Atomic Absorption Spectrophotometry, the soil’s organic carbon content and cation exchange capability were also evaluated. This was used to report the amount of soil toxicity.

Key words: Heavy metals, Spectrophotometry, organic carbon, Coal mining activities
