前言我院继对珠江口海区砷污染调查后,于1979—1980年曾对韶关市、曲江县、连南县等地土法炼砷对环境污染情况进行了调查。鉴于日本于1973年将报废炼砷矿场污染环境引起的慢性砷中毒症定为第四公害病,以及世界癌症研究所于1979年宣布无机砷化合物为人类皮肤癌与肺癌的致癌物质。我们曾提出禁止土法炼砷等建议。环保部门曾发出禁止土法炼砷的通知。但自1981年以来,由于砷价上涨,该地带顿时兴建了许多新炼砷窑炉。计有39个炼砷点和91条炼砷窑。分布在阳山、连南、连县、乳源、始兴、曲江、乐
Foreword Following the investigation of arsenic contamination in the Pearl River Estuary, our hospital investigated the environmental pollution caused by arsenic in Shaoguan, Qujiang and Liannan counties from 1979 to 1980. In view of the fact that chronic arsenicosis caused by environmental pollution from scrapped arsenic mines in Japan was classified as the fourth public hazard in Japan in 1973, and the World Cancer Institute announced in 1979 that inorganic arsenic compounds are carcinogenic to human skin and lung cancer. We have put forward a proposal to ban the indigenous method of arsenic refining. The environmental protection department has issued a notice banning native arsenic. However, since 1981, due to the rise in arsenic prices, many new smelting furnaces were immediately constructed in the zone. There are 39 refining arsenic points and 91 refining arsenic kiln.
