城郊农业对许多发展中国家的城市人口至关重要。工业化和城市化的加剧以及相关的空气污染威胁着城市粮食生产和质量。监测了SO2、NO2和O-3的6小时平均浓度，并测量了植物的生理特性、色素、生物量和产量。种植在印度瓦拉纳西城市边缘的绿豆(Vigna Radiata)、绿豆(Palak)、小麦(Triticum Aestivum)和芥菜(Brassica Compestris)的参数减少与气体污染物水平直接相关。反应的大小涉及所有三种气态污染物在禁令周围的地点；O-3在农村地点的影响更大。研究得出结论，瓦拉纳西的空气污染可能会对作物产量产生负面影响。(C)2003爱思唯尔有限公司。保留所有权利。
Peri-urban agriculture is vital for the urban populations of many developing countries. Increases in both industrialization and urbanization, and associated air pollution threaten urban food production and its quality. Six hour mean concentrations were monitored for SO2, NO2 and O-3 and plant responses were measured in terms of physiological characteristics, pigment, biomass and yield. Parameter reductions in mung bean (Vigna radiata), palak (Beta vulgaris), wheat (Triticum aestivum) and mustard (Brassica compestris) grown within the urban fringes of Varanasi, India correlated directly with the gaseous pollutants levels. The magnitude of response involved all three gaseous pollutants at peri-m-ban sites; O-3 had more influence at a rural site. The study concluded that air pollution in Varanasi could negatively influence crop yield. (C) 2003 Elsevier Ltd. All rights reserved.
