“…Since the 1970s, higher plant bioassays have been recommended for use in mutation screening and monitoring for the detection of genotoxins in emissions, effluents, or ambient environmental media by the Royal Swedish Academy of Sciences (1973), Committee 17 of the Environmental Mutagen Society (1975), the World Health Organization (1985) and the National Swedish Environmental Protection Board in 1989 (Fiskesjö 1993a). For some years cytogeneticists working with higher plant genotoxic assays have suggested that these assays be accepted as an alternate first-tier assay system in safety evaluation programs as they are easy to handle, inexpensive, require minimum space (Baburek et al 1997) and are ideal for use by scientists in developing countries (Grant 1994). Higher plants can be exposed for periods of a few minutes to days or weeks, thus simulating acute workplace exposures as well as chronic exposure to ambient atmospheres.…”

“…Recently, Baburek et al (1997) have developed a cotyledon assay for testing for mutagenicity. Nicotiana tabacum plants heterozygous for the sulphur gene (Su), a nuclear gene that affects chlorphyll content in leaves, gives a codominant phenotype (genotype Su/Su, dark green; Su/su, light green; su/su, albino).…”

Since the beginning of time pollution has been created by human activities. However, the intensity and the severity of the different kinds of pollution have emerged only in the last few decades and many intricate facets have been revealed. It is gradually being recognized that our health and the ecosystem are being severely affected by environmental chemicals that enter the atmosphere. Plants comprise a large portion of our biosphere and constitute a vital link in the food chain. In this review, types of mutagenic chemicals found both indoor and outdoor are given and several higher plant bioassays for screening and monitoring environmental mutagens are discussed. One plant ideal for monitoring and testing for air pollution is Tradescantia. This species has been used to test for mutagenicity of radioisotope‐contaminated air following the Chernobyl nuclear accident and monitoring around nuclear power plants. One of the greatest contributions of plant bioassays will be their continued use for ambient air monitoring and testing for genotoxicity which can be carried out on a global scale.
