不同蔬菜对潮褐土镉铅锌复合污染的吸收效应研究

在潮褐土Cd、Pb、Zn污染区，采集不同蔬菜和土壤样品，对其中所含的Cd、Pb、Zn的含量进行了测定。结果表明，胡萝卜、茄子、芥菜、丝瓜、番茄、辣椒属低度累积型；白萝卜、菜花、莴苣、大葱、小白菜、韭菜为中度累积型；芹菜、茴香、香菜、圆白菜、蓬蒿属重度累积型；白菜、油菜可归为极重度累积型。

Effects of Complex Contamination of Cadmium, Lead and Zinc on Vegetables Grown in Meadow Cinnamon Soil

A survey was done to evaluate the pollution of heavy metals on vegetables in an agricultural region. According to the characteristics of Cd, Pb, and Zn, and accumulation in edible parts of the vegetables grown in the area of meadow cinnamon soil contaminated with Cd, Pb, and Zn, the vegetables were roughly divided into four classes: light, middle, heavy and extremely heavy. Carrot, eggplant, rutabaga, towel gourd, tomato and hot pepper belonged to light degree of accumulation class; white radish, cauliflower, lettuce, onion, little Chinese cabbage, and fragrant- flowered garlic belonged to middle degree of accumulation class; while celery, fennel, coriander, ball Chinese cabbage, and fleabane belonged to heavy degree of accumulation class; Chinese cabbage and rape belonged to extremely heavy degree of accumulation class.
