Demands on an early detection method for lead (Pb), found as a pollutant in soil, are urgently needed to improve awareness on the continuing usage of waste water and industrial effluent for the agricultural practices especially in East Java, Indonesia. Ma rsilea crenata plant grown in a glasshouse under various concentration of Pb to indicate its tolerance to Pb stress is measured by its weekly biolectrical responses. The result shows that increasing Pb concentration tends to inhibit the plant’s growth. It i s concluded that the method is viable as an early detection remediatio n process to protect agricultural economy and human security.
