This standard is a revision of NY5010—2001 "Environmental conditions for vegetable production areas for pollution-free food" issued on September 3, 2001. This revision deleted the terms and definitions of pollution-free vegetable production areas and environments, deleted the nitrogen dioxide index in the ambient air quality requirements, the fluoride index in the irrigation water quality requirements, and the copper index in the soil environmental quality requirements, and modified the sulfur dioxide and fluoride indexes in the ambient air quality requirements, the total cadmium, total lead, and fecal coliform group indexes in the irrigation water quality requirements, and the concentration (content) limits and applicable scopes of cadmium, mercury, lead, and arsenic indexes in the soil environmental quality requirements. NY5010-2001 "Environmental Conditions for Pollution-free Food Vegetable Production Areas" will be abolished as of the date of publication of this standard. This standard was proposed by the Ministry of Agriculture of the People's Republic of China. This standard was revised by the Ministry of Agriculture Environmental Quality Supervision, Inspection and Testing Center (Tianjin). The main revisers of this standard are: Gao Huaiyou, Liu Fengzhi, Li Yujin, Liu Xiaowei, and Zheng Xiangqun. The previous versions replaced by this standard are: NY5010—2001.98
