Could the fluoride-tolerant species Panicum maximum replace sensitive plants in fluoride biomonitoring?

Fluoride (F) is the most phytotoxic atmospheric pollutant. The use of plants for passive or active biomonitoring has been a common strategy to detect abnormal atmospheric F concentrations. Tree species are mostly used, although the high sensitivities of some, associated with costly processes of plan...
