农莉在农产品中的残留,关系到广大农产品消费者的健康。在目前广泛使用农药情况下,已成为国际上重大卫生问题之一。许多国家设有专门研究和管理机构,联合国也成立了专门调查研究组织。 三、农药在农产品中的残留 无机农药的毒性是由于某一元素本身的特性而发生作用,在动、植物体内(外)不进行降解解毒过程(见后)。例如,苹果表面上沾附的砷酸铅,非常牢固,虽然可经雨水的淋洗或若干金属离子影响而进行分子变化,但只要有砷离子存在就仍能维持其毒性。据报导苹果表面每平方厘米至少沾附有12 56微克的(?)
Peasants in the residual agricultural products, related to the general health of consumers of agricultural products. Under the current widespread use of pesticides, it has become one of the major international health problems. Many countries have specialized research and management agencies and the United Nations also set up special investigation and research organizations. Third, the pesticide residues in agricultural products The toxicity of inorganic pesticides is due to the characteristics of a particular element and play a role in the animals and plants (outside) without detoxification process (see below). For example, the lead arsenate attached to the surface of apple is very firm. Although it can undergo molecular change under the influence of rainwater leaching or metal ions, its toxicity can be maintained as long as arsenic ions are present. It is reported that apple surface with at least 12 56 micrograms per square centimeter (?
