摘要
通过对比典型剖面上的石煤及其风化发育的土壤的氟含量、流经石煤层的水与不经过石煤层的水的氟含量,研究石煤风化、淋溶时氟对土壤、地表水和农作物的影响。采集居民家中石煤、石煤燃后底灰、室内降尘、玉米、辣椒、水缸水和开水,分析其含氟量,研究石煤燃烧时氟的迁移富集机制。结果表明石煤的风化、淋溶虽导致土壤含氟量大幅升高但对地表水和新鲜粮食的含氟量无显著影响;石煤燃烧后释放出的氟污染室内玉米、辣椒和饮水,导致氟中毒流行。
Contrasting stone coal to the soil developed from it and water to water leached from stone coal shows that slight fluorine pollution of surface water and plant resulted from weathering of stone coal and leaching. Stone coal and its ash, dust, corn, chili, water in vat and boiled water were sampled from the inhabitants' houses, and fluorine in these media was determined. It is shown that fluorine released from stone coal combustion is an important factor leading to serious fluorosis.
