| Abstract: | The lichen Ramalina stenospora was collected from 16 location in Calcasieu Parish and from 2 locations in Cameron Parish in Southwestern Louisiana. The metals V, Mn, and Al were measured in lichen specimens collected during three seasons — fall 1983, winter and spring 1984. The metals were determined using thermal neutron activation analysis. Vanadium was found to range in concentration from 2.1 to 10 mg kg?1; and Al from 900 to 4500 mg kg?1. Metal concentration was found to decrease exponentially with distance outward from the industrial corridor. The major industries included were an Al plant, two refineries and five chemical plants mostly related to plastics production. |
