生产性毒物的理化性质,往往对毒物进入人体的机会及其在体内的代谢转化等产生重要的影响,因此,要做好职业中毒的防治工作,就应该重视和掌握生产性毒物的理化性质。现简介它们之间的关系,以供交流。一、理化性质与毒性和危害性关系所谓理化性质,通常是指物质的溶解度、分散度、挥发度和比重等。某些化学物质的溶解度与其毒性有密切关系,如吡霜(A_(S2)O_3)与雌黄(AS_2S_3)相比,前者的溶解度大,毒性比后者也大得多。分散度高的毒物,化学活性大,如氧化
The physical and chemical properties of productive poisons often have an important influence on the chances of poison entering the human body and their metabolic transformation in the body. Therefore, in order to prevent and control occupational poisoning, the physicochemical properties of the poisons should be emphasized and mastered. Now introduce the relationship between them, for exchange. First, the physical and chemical properties and toxicity and harmful relationship The so-called physical and chemical properties, usually refers to the solubility of substances, dispersion, volatility and specific gravity. The solubility of some chemical substances is closely related to their toxicity. For example, the solubility of pyridoxine (A_ (S2) O_3) is much higher than that of estrogen (AS_2S_3), and its toxicity is much greater than the latter. High degree of dispersion of poisons, chemical activity, such as oxidation
