树脂砂的二恶英和呋喃污染

Dioxin and Furan Pollution of Resin Sands

二恶英和呋喃被称为“环境激素”，是被联合国2001斯德哥摩公约禁止或限止的12种持久性有机污染物中的2种，它们能严重损害人类和高级动物的内分泌和生殖系统，并具有致癌性。铸造业中一切树脂砂在浇注中不但释出具有强刺激性有害物质，而且由于不完全燃烧和热解，易于释出二恶英、呋喃和苯并芘。铸造工作者应该对它们的危害性给予充分的重视。

Abstrac Dioxin and furan ,the so-called environment hormones,are the two of the 12permanent organic pollutants forbidden or limited by 2001Stockholm Agreement of UN. They can seriously injure the human and highclass animal glandular excretion system and genitals system. In foundry, all resin sands liberate out a lot of irritant and harmful odours and gases,and also the environmental hormones of a-benzopyrene dioxin and furan because of the inadequate combustion and thermal decompose of organic compounds. The foundry men ought to give great attention to the troubles of these organic pollutants.
