Impact assessment of magnesium in the ground soil and suspended particulate matter in the ambient air of Kumaun region of lesser Himalayas

A high concentration of magnesium, also known as a secondary soil nutrient, along with suspended particulate matter (SPM), can have adverse effects on soil quality. This study aims to assess the impact of magnesium in the soil and suspended particulate matter in the air around the hills of magnesite mining areas. Additionally, it seeks to determine how mining coupled with a manufacturing unit located in this area posed a challenge to the pristine environment of these hills. The Na₂CO₃ fusion method was employed to analyse ground samples of soil, rocks, and suspended solids. Laboratory findings revealed that the presence of magnesium and suspended particulate matter was primarily limited to immediate vicinity of the mine area.
