陕西白水县无公害苹果园环境质量评价

监测了陕西白水县无公害苹果生产示范区大气、土壤、灌溉水的质量,并对其进行了评价。监测结果表明,无公害苹果生产的4项大气质量指标、6项土壤质量指标和6项灌溉水质量指标均未超过国家《无公害食品苹果产地环境条件》限制,产地环境条件完全能够满足无公害苹果生产的要求。评价结果还表明,可悬浮颗粒物、As和Cd有可能成为无公害苹果生产示范区大气、土壤和灌溉水未来的主要污染物,并提出提倡果园种草,增加植被覆盖,降低大气可悬浮物,减少苹果果面污染,禁止果园使用福美砷等砷制剂,以避免土壤砷污染的增加等措施。

Environmental quality evaluation of environmental friendly apple production base of Baishui County

Environmental quality evaluation of atmosphere,soil and irrigation water in environmental friendly apple production base of Baishui County is monitored in this paper.The monitoring result showed that 4 atmosphere polluters,6 soil polluters and 6 irrigation water polluters are all in the range of "environmental friendly apple producing environmental condition",the demonstrating area can be used as environmental friendly apple production base.The evaluating results demonstrate that the suspending polluter in atmosphere,arsenic in soil and cadmium in irrigating water may become the main polluters in atmosphere,soil and irrigating water respectively in the following years,we proposed to seed grass,increase matted vegetation,decrease suspending polluters in the atmosphere,thus to decrease the pollution of apple surface,and to forbidding asomate and other arsenic pesticides to pollute soil continuously.
