Abstract

ABSTRACT

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.

空气污染环境中遗传毒性检测的高等植物试验

【摘要】自古以来，污染就是人类活动造成的。然而，各种污染的强度和严重程度只是在最近几十年才显现出来，许多错综复杂的方面已经显露出来。人们逐渐认识到，我们的健康和生态系统正受到进入大气的环境化学物质的严重影响。植物占我们生物圈的很大一部分，是食物链中的重要一环。本文综述了室内和室外发现的诱变化学物质的类型，并讨论了几种用于筛选和监测环境诱变物质的高等植物生物测定方法。一个理想的监测和测试空气污染的工厂是Tradescantia。在切尔诺贝利核事故发生后，该物种已被用于放射性同位素污染空气的致突变性测试和核电站周围的监测。植物生物测定的最大贡献之一将是它们继续用于环境空气监测和遗传毒性测试，这可以在全球范围内进行。
