蔬菜设施内环境空气质量评价指标及标准值的探讨

Ambient air quality indexes and standards for vegetable growing in greenhouses

摘要: 该文探讨了设施蔬菜棚室内环境空气质量评价指标的筛选与定值原则，提出以可吸入颗粒物、二氧化硫、二氧化氮、铅、氟化物、一氧化碳、苯并［a］芘、氨气、氯气、乙烯10种污染物作为设施蔬菜棚室内环境空气质量的评价指标。参考国外相应标准，结合我国设施蔬菜生产的实际情况，提出了每种污染物的最高允许浓度。

Abstract: The key points of choosing the evaluation indexes and determining maximum limited values of the toxic substances in greenhouse ambient air for vegetable growing were discussed in this paper, PM₁₀, SO₂, NO₂, Pb, Fluoride, CO, BaP, NH₃, Cl₂, C₂H₂ were selected as the evaluation indexes, and their maximum limited values were given. Comparing with the correlative criteria of WHO, America, Canada, Australia and other countries, taking account of the status quo in China, the maximum limited values of each toxic substance were given by the author.
