抽象的:
巴基斯坦是居住在神话和围城地区大多数人口的发展中国家之一。虽然工业化进程缓慢,服务业不断发展,但农业仍然是经济的支柱。主要农作物、水果和蔬菜是最重要的生产系统。蔬菜生产基本上是次要的,主要作物是灌溉用水的主要用户。蔬菜生产主要集中在该国的城市周边地区。在其他挑战中,蔬菜生产也受到了清洁灌溉用水短缺的影响,导致蔬菜生产使用污水。污水可作为经处理(再生水)或未经处理(原废水)的灌溉水源。污水要么直接用于灌溉农作物,要么从水处理厂排放出来。在巴基斯坦经处理和未经处理的污水中,各种有毒化学品和工业废水的浓度很高。城市和城市周边地区的污水也含有大量的金属,如锌、锰、镍、铬、镉和铅。 The proposed study was conducted in peri-urban areas of Faisalabad. Initially four towns were selected through random stratified sampling and each comprising of 30 respondents. A sample of 120 respondents was selected. Information was gathered through semi structured interviews, scheduled either at the farms or the houses of respondents. The information gathered was analyzed using SPSS.
