Abstract: | In this article are reported the results of a study on the concentration of ascorbic acid (AA) in Mangifera indica as passive monitor and in Phaseolus vulgaris as active monitor with the intention to study the e4ects of industrial emissions from the Petrochemical Complex of Camayari (PCC), Bahia, Brazil, on the vegetation. Leaves from M. indica were collected in two sites in the region under direct in6uence of industrial emissions and in one presumed nonpolluted reference (background) site. Pots with P. vulgaris were exposed in the same sites. The AA increase in the leaves of M. indica from PCC sites indicates a stress situation. The small AA increase in the P. vulgaris exposed in the more polluted site indicates that the active monitor is a sensitive one. The decrease of its leaf area indicates the inability of this specie to activate physiological protection mechanisms like an increase in AA production. |
