目前在苏联以及全世界都对环境保护,给予很大的注意。为了保存生物群落,清洁环境和保护人类健康,科学工作者要不断努力进行研究,尽可能降低和完垒排除在农业中应用各种化学药剂所带来的不良影响。由于除草剂对作物具有高度的生物活性和毒性,必须系统的研究其化学物质在环境中和生物有机体内的转化规律。通过采用微量分析方法(光谱法、薄层法、气相色谱法等)就有可能测定除草剂在植物
At present, great attention is paid to environmental protection in the Soviet Union as well as the rest of the world. In order to preserve biological communities, clean the environment and protect human health, scientists must make continuous efforts to study and minimize or eliminate as far as possible the adverse effects of using various chemicals in agriculture. Due to their high biological activity and toxicity to crops, herbicides must systematically study the transformation rules of their chemicals in the environment and in the living organism. By using microanalysis methods (spectroscopy, thin-layer methods, gas chromatography, etc.) it is possible to determine the effect of herbicides on plants
