The use of plants for environmental monitoring and assessment.
This paper presents a critical review on phytotoxicity tests for environmental monitoring and assessment. Vascular macrophytes used in the laboratory testing are emphasized; algae are mentioned only for comparison. Several issues are discussed, including the rationale for and misconceptions about phytotoxicity tests, relation to regulation, status of phytotoxicity test protocols, advantages and disadvantages of phytotoxicity tests, and possible research directions. Aquatic and terrestrial macrophytes, along with algae, are essential components of ecosystems. Macrophytes are becoming more important for the monitoring and assessment of herbicides, effluents, and industrial chemicals. In the United States, Canada, and international organizations, phytotoxicity tests can be required for environmental monitoring and assessment in statutes such as Federal Insecticide, Fungicide, and Rodenticide Act; Toxic Substances Control Act; Water Quality Act; Canadian Pest Control Products Act; and Canadian Environmental Protection Act. Possible research directions for phytotoxicity tests are discussed relative to the role in regulations of industrial chemicals, effluents, hazardous waste sites, and pesticides.
