介绍电子束辐照处理邻苯二甲酸酯类和甾体雌激素类环境内分泌干扰物、氯霉素类和左旋苯甘氨酸抗生素类药物及其中间体、农药中的二氯吡啶酸，以及卤代芳香化合物的辐照降解特性和机理.结果表明，电子束辐照是处理这些有机物污染物的一种十分有效的方法，羟基自由基和水合电子在有机污染物的降解过程中起到十分重要的作用.羟基自由基可以使有机污染物的苯环打开生成小分子物质，而水合电子可使有机污染物有效地脱卤，并且在剂量足够大的情况下，使其最终被完全矿化为二氧化碳和水.

This article introduces degradation characteristics and mechanisms of electron beam irradiation in the treatment of organic pollutants. These include phthalate esters and steroid estrogens, antibiotics drugs and its intermediate such as choramphenicols and Dphenylglycin, and clopyralid in pesticides and halobenzenes. The results indicate that electron beam irradiation is an effective method to degrade these kinds of persistent organic pollutants. Hydroxyl radicals and hydrated electrons have great importance in the process of radiolytic degradation. Hydroxyl radicals attack aromatic ring of these organic pollutants leading to the fracture of benzene ring, and form a series of micromolecular byproducts, while hydrated electrons can effectively remove halogen of organic pollutants. Organic pollutants are then completely mineralized when absorbed dose is high enough.
