土法炼磺是我国农村的新型产业,但是土法炼磺工艺落后,设备简陋,给农村的环境和农民的健康带来了一定危害。山西省吕梁地区1986年曾对交口县一乡办硫磺厂调查测试发现,每立方米大气中平均二氧化硫浓度高达89.5mg,超过国家规定标准的42倍,每立方米空气中平均含硫化氢65mg,超过国家标准12.5倍,还有二硫化碳,一氧化碳,氮氧化物等。由于长期吸收有害气体,慢性咽炎、慢性鼻炎等患者高达45.23%,全厂194名工人,建厂后几年时间就有14人患不同程度的矽肺病,同时污染了环境、河流和水库,当地寸草不生,大部分梨、核桃和枣树枯死。
Soil refining sulfur is a new type of industry in rural areas, but the indigenous method of refining sulfur lagging behind, poorly equipped, to the rural environment and the health of farmers brought some harm. In 1986, Lvliang Prefecture, Shanxi Province, conducted a survey on the sulfur plant in Jiaokou County, a township. It found that the average concentration of sulfur dioxide per cubic meter of the atmosphere reached as high as 89.5mg, which exceeded the national standard by 42 times and the average amount of hydrogen sulfide per cubic meter of air was 65mg. More than 12.5 times the national standard, as well as carbon disulfide, carbon monoxide, nitrogen oxides. As a result of long-term absorption of harmful gases, chronic pharyngitis, chronic rhinitis and other patients as high as 45.23%, the whole plant 194 workers, a few years after the construction of 14 people suffering from varying degrees of silicosis, polluting the environment, rivers and reservoirs, local Incombustible, most pears, walnuts and dates dead.
