Abstract


The study of metals as atmospheric pollutant has been done in Bandung. Particularly observation was done at thallus of lichens of Parmelia wallichiana and metals accumulated by lichens. The metal contents of the lichen thallus from 6 stations observation have been measured by neutron activation analysis. The result of researches showed that Parmelia wallichina can accumulate metals such as Al, Co, Cr, Mn, Na, V, Cl, Fe, Hg, Rb, Sb, Sc, Th, Sm, Zn, dan Zr. The concentration of Al, Cr, Fe, Mn, Na, and V was high in thallus from Jamika area (West of Bandung). While the concentration of Sb and Zn was high in thallus from Alun-alun area (Central of Bandung ). The effect of metals contaminants to P. wallichiana have caused the colour of thallus changing from green (Dago Pakar area) to become pale green in polluted area. The metal pollution in atmospheric of Bandung have accured and was probably as followed: 1)High polluted areas: Jamika (West of Bandung). 2) Moderate polluted area: Alun-alun (Central of Bandung), Antapani (East of Bandung), and Mohamad Toha (South of Bandung). 3) Slight polluted area: Taman Sari (North of Bandung). 4)Clean air area: Dago Pakar .
