Heavy metal is a general technical term that applies to the group of metals and metalloids with density greater than 4±1 g cm-3 or elements having atomic weight more than 20. Heavy metals are considered toxic to living organisms and even trace metals that are considered essential for life can be toxic when present at excessive level, impair important biochemical process and also pose threat to human health, plant growth and animal life. The heavy metals, As, Cd, Cr, Ni and Pb were found accumulated in seeds collected from various sites. Higher concentrations of Pb were found in seeds of L. leucocephala collected from National Highway 21-A (2.650 mg/Kg), Baddi Barotiwala link road (1.35 mg/Kg) and Kalka Charnia link road (1.195 mg/Kg) against control (0.960 mg/Kg). Ni was recorded in higher quantities in seeds of T. ciliata and D. sissoo collected from roadside sites as compared to control.
