选择3种类型茶场进行大气氟污染与茶叶氟富集的现场监测与研究,对苏南茶区11个茶场的土壤总氟、水溶性氟和茶叶氟富集量进行了测定。结果表明:茶叶氟富集量与来自砖瓦窑厂的大气氟污染浓度呈现高度的正相关,与土壤含氟量不呈现相关;茶树是高富集氟的植物,富集能力远高于一般植物,氟富集量可达每千克数十至数百毫克。茶叶的氟富集与氟污染应引起重视
Three kinds of tea farms were selected to carry out on-the-spot monitoring and research on fluoride pollution in the atmosphere and fluorine enrichment in tea. The total fluorine, water-soluble fluorine and tea fluoride content in 11 tea farms in the southern Jiangsu tea area were determined. The results showed that there was a positive correlation between fluoride enrichment in tea and atmospheric fluoride pollution from brick-tile kiln plant, and no correlation with fluorine content in soil. Tea plant was a high fluorine-enriched plant, and its enrichment capacity was much higher than normal Plants, fluoride enrichment up to tens to hundreds of milligrams per kilogram. Fluorine enrichment and fluorine pollution should pay attention to tea
