摘要
为科学评估有机枸杞产地环境是否符合有机生产标准,本研究基于监测数据,依据GB/T 19630—2019等国家标准,对甘肃省瓜州县有机枸杞产地土壤环境污染物、农田灌溉用水污染物、环境空气污染物和缓冲带设置合理性进行了全面评价。结果表明,研究区土壤中汞、砷、铅、铬、铜、镍、锌含量均小于风险筛选值,滴滴涕(总量)、苯并[α]芘、六六六(总量)未检出;pH、水温等16项农田灌溉水质基本控制项目与大肠埃希氏菌、砷等37项生产用水补充分析项目均检测合格;研究区2022年和2023年PM_(10)、PM_(2.5)等6项环境空气污染物浓度均低于项目限值;研究区缓冲带设置30~50 m,未检出周边农作物的化学药剂和化肥投入物,检出砷、汞、铬含量微小。综合表明,有机枸杞试验示范园的选址位置、土壤污染物、农田灌溉水质基本控制项目、环境空气质量、缓冲带设置等指标整体良好,为开展有机枸杞生产提供可靠的产地环境保障。
To scientifically assess whether the environmental conditions of organic wolfberry production areas meet the organic production standards,this study conducted a comprehensive evaluation of soil environmental pollutants,farmland irrigation water pollutants,ambient air pollutants,and the rationality of buffer zone settings in the organic wolfberry production area of Guazhou County,Gansu Province,based on monitoring data and in accordance with national standards such as GB/T 19630-2019.The results showed that the contents of Hg,As,Pb,Cr,Cu,Ni,and Zn in the soil of the study area were all lower than the risk screening values,while total DDT,benzo[α]pyrene,and total HCH were not detected.16 basic control items for farmland irrigation water quality(including pH and water temperature)and 37 supplementary test items for production water(including Escherichia coli and As)all passed the detection.The concentrations of 6 ambient air pollutants(including PM_(10)and PM_(2.5))in the study area in 2022 and 2023 were all below the specified limits.The buffer zones in the study area were set at 30–50 m,no chemical agents or chemical fertilizer inputs from surrounding crops were detected,and only trace amounts of As,Hg,and Cr were found.Overall,the indicators such as the site selection of the organic wolfberry experimental and demonstration garden,soil pollutant levels,basic control items for farmland irrigation water quality,ambient air quality,and buffer zone settings are generally favorable,providing a reliable environmental guarantee for the production area to carry out organic wolfberry cultivation.
