摘要
呼市蔬菜区长期受工业“三废”排放的影响,农业生态系统已经受到一定程度的污染。本文通过对呼市蔬菜区土壤和蔬菜中B(a)P污染物的分析和研究,结果表明土壤中B(a)P的含量范围在5.5—63.13PPb之间,蔬菜中B(a)P含量范围在0.25—5.00PPb内,不同的蔬菜对B(a)P的吸收能力不同,土壤有一半受到B(a)P污染影响;对蔬菜的综合评价认为,除个别地方外,蔬菜大部分没有受到B(a)P污染。其污染源主要是大气污染所致,并提出了防治B(a)P污染的对策。
The agro-ecosystem in the suburb of Huhhot has been polluted to someextent with industrial 'Three Wastes'. The paper measures and analyzes thepollutant (B(a)P) in vegetables and soils, and discusses the data. The re-sults are as follows: The contents of B(a)P in the soils range from 5.5 to63.13, 0.25 to 5.00 ppb in the vegetables; Different vegetable has differentabsorbent power to B(a)P, i. e. greenbean>earat>cabbage>green pepper>potato; Half of the soils have been polluted with B(a)P, and most vegetab-les have not been polluted with B (a) p with some exceptions. The authorthinks the air pollution is main way, and gives the countermeasures againstB(a)P pollution.
