    摘要:

    目的:调查北京和河北地区生鲜乳和牧场投入品中重金属污染情况。方法:针对北京和河北地区养殖场分布情况,采集这两个地区35家牧场的生鲜乳样和北京地区3家规模牧场中饲料、生产用水等投入品样,开展铅污染状况的风险监测。结果:北京地区3家牧场的52份饲料样品铅的含量未超出标准限量要求,6份用水样品未检出铅的含量,饲料和用水合格率均为100%;北京和河北地区奶牛养殖场35份生鲜乳合格率为100%。结论:北京地区牧场投入品的安全性较好,北京和河北地区的生鲜乳无明显受重金属铅的污染,通过本文不仅了解北京和河北地区生鲜乳中铅污染水平,同时也为制修订标准、风险预警和风险评估提供了参考数据。

    Abstract:

    Objective: To investigate the fresh milk and farm inputs of Beijing and Hebei districts of heavy metal pollution condition. Methods: The fresh milk samples of 35 farms in Beijing and Hebei districts, as well as the feed and production water as inputs from 3 large-scale farms in Beijing were collected to carry out risk monitoring of lead pollution based on the distribution of farms in these two districts. Results: There were no exceeding the standard limit requirements of lead contents in 52 feed samples and no lead detected in 6 water samples from 3 farms in Beijing district. The qualification rate of feed and water samples was 100%. The qualification rate of 35 fresh milk samples from farms in Beijing and Hebei regions was 100%. Conclusion: The farm inputs of Beijing district was safe, and there was no significant lead pollution in fresh milk from farms in Beijing and Hebei districts. This paper not only summarized the lead pollution level of fresh milk in Beijing and Hebei districts, but also provided reference data for formulating standards, risk early warning and risk assessment.
