Abstract

In the present study individual effect of Pb, Ni and Cd respectively was studied on protein and fat content of the moss Thuidium cymbifolium. A decrease in protein content was noticed in moss treated with Ni and Cd for 3 days, whereas for Pb an increase of 18 % was noticed at 0.1 M conc. However following an exposure period of 6 days, a significant increase in protein content was noticed for all metals, which again declined after 15 days of treatment. A significant increase in fat content of the moss (136 % and 269 % at 0.1 and 0.2 M Pb) was noted after 3 days. Conversely the increase in Cd ranged between 1-27 % during 72 hrs treatment that further increased to 77 % at 0.2 M Cd concentration following 6 days of exposure. After 15 days of Pb, Ni and Cd treatment a more or less decreasing trend was noticed with increasing concentration. Results revealed that T. cymbifolium shows heavy metal sensitivity as evidenced by change in protein and fat content.
