目的了解内蒙古地区市售蔬菜中农药残留状况,为蔬菜监管、标准制修订及风险评估提供科学依据。方法2019—2020年春季(3-4月)和秋季(9-10月),在内蒙古自治区12个盟市采集市售蔬菜样品各20份,按照《国家食品中化学污染物及有害因素监测工作手册》中的方法对9种杀虫剂、13种杀菌剂及二硫代氨基甲酸酯类(以CS2计)农药残留含量进行检测;依据《食品安全国家标准食品中农药最大残留限量GB 2763—2019》对蔬菜中农药残留情况进行评判价。结果480份蔬菜中,9种杀虫剂、13种杀菌剂、二硫代氨基甲酸酯类(以CS2计)检出率分别为11.04%(53/480)、34.79%(167/480)、27.71%(133/480),超标率分别为3.33%(16/480)、1.46%(7/480)、2.29%(11/480),农药残留超标的蔬菜主要为芹菜、韭菜、白菜、菠菜。结论内蒙古地区12盟市市售蔬菜中存在农药残留及超标现象,有高毒与剧毒农药检出;且存在单种蔬菜中杀菌剂农药共残留情况,建议相关部门加强农药生产与使用的监管。

目的分析2018年我国蔬菜的食品安全形势。方法汇总2018年蔬菜国家食品安全监督抽检结果,对不合格项目等信息进行分析。结果 2018年共抽检蔬菜2077批次,检出不合格样品68批次,总体合格率为96.7%。抽检的16种蔬菜中,菠菜的合格率仅为85.2%,芹菜、韭菜、普通白菜、豇豆的合格率分别为87.3%、89.8%、90.8%和94.4%,姜和黄瓜的合格率分别为98.8%和99.4%,其余9种蔬菜未检出不合格。菠菜、芹菜、普通白菜的不合格原因主要是毒死蜱超标,韭菜的不合格原因主要是腐霉利超标。结论菠菜、芹菜、韭菜、普通白菜的合格率偏低,毒死蜱、腐霉利等农药超标是主要的食品安全问题。

现有的瑞雷波数据处理方法通常只能计算得到地震排列下方岩土体平均相速度,造成探测结果的水平分辨率较低。为了解决这一问题,利用choi-Williams分布得到瑞雷波时间、频率和幅度之间的关系,通过相邻两道不同频率瑞雷波波形的整体时间差,计算瑞雷波频散曲线。结合各道之间瑞雷波频散曲线,得到地震排列下方岩土体瑞雷波相速度-深度剖面。此方法应用于近地表老窑探测,得到了老窑空间分布情况。

目的研发一种可使用较少减影影像生成高精确度、高稳定性的动脉自旋标记(ASL)灌注影像的深度学习算法。材料与方法使用卷积神经网络(CNN)作为深度学习算法,以使ASL影像生成来自于成对减法(pair-wise subtraction)。真实的灌注影像来自于6或7个成对相减的影像的平均值。该成对影像来自于(1)7名正常受试者常规的、假性连续的ASL图,(2)114例不同疾病病人的Hadamard编码假性连续ASL图。CNN经过训练可以从较小的(2或3个)减法影像中生成灌注影像,并通过交叉验证来评估。来自于病人数据库的CNN也在26例独立的卒中病人数据集中进行了验证。通过配对t检验和/或Wilcoxon秩检验,将CNN与传统的平均方法学进行比较,包括:均方误差、放射评分。结果对于交叉试验健康受试者、病人和单独测试曾经历了一次卒中的病人(Pmin)∶(43.2±29.8)m L/(100 g·min),P<0.001]。通过放射评分证实CNN噪声和运动抑制和/或分割伪影优于传统的平均法。结论与传统的平均法生成ASL影像相比,CNN法获得的灌注影像质量更好,灌注测量更准确。
