Abstract

With the aim to obtain information about atmospheric deposition of metals all over the western Himalayas (Kumaon region) using moss as bioaccumulator, a biomonitoring program was setup by financial aid of the Department of Biotechnology, Ministry of Science and Technology, Govt. of India. Present study is a part of the same monitoring program. The moss Racomitrium crispulum was sampled from 24 localities of Nainital of the Kumaon Hills to indicate relative level of four metals: Pb, Zn, Cu and Cd. In summation of undertaken metals the highest 70% concentration of metals was observed in centre of the city. A gradient of decrease in metal was recorded while projecting away from city centre (zero km). A trend of metal precipitation was observed amongst seasons, viz. summer > winter > monsoon. The accumulation level of metals in the moss also varies amongst themselves, i.e. Zn > Pb > Cu > Cd. The moss metal-metal regression analysis correlation (R) exhibits that it gives significance for Pb-Zn (0.8088), Cu-Zn (0.6186) and Cu-Pb (0.5611).
