为考察土壤理化性质的差异对土壤中污染物的风险控制值计算结果的影响,以上海为研究区采集296个土样进行土壤理化性质参数分析,参考《建设用地土壤污染风险评估技术导则》(HJ 25.3—2019)中的方法计算不同污染物的土壤风险控制值,并与《土壤环境质量建设用地土壤污染风险管控标准(试行)》(GB 36600—2018)中的风险筛选值进行比较。结果表明,研究区土壤为典型的黏性土壤特性,其土壤理化性质参数与HJ 25.3—2019推荐值有明显差异;土壤理化参数的取值主要影响挥发性有机污染物的风险计算结果;以研究区实测的土壤理化参数背景值来计算25种挥发性有机污染物在第一、二类用地的土壤风险控制值,结果与GB 36600—2018的风险筛选值相比存在不同程度的差异。采用Crystal Ball模型计算土壤容重(ρ_(b))、包气带土层孔隙水体积比(θ_(ws))、包气带土层孔隙空气体积比(θ_(as))和土壤有机碳质量分数(f_(oc))对土壤风险控制值的敏感性,4个参数敏感性排序为ρ_(b)>f_(oc)>θ_(ws)>θ_(as);污染物物理性质会影响土壤理化性质对土壤风险控制值计算的敏感性;研究区域土壤θ_(as)、θ_(ws)与HJ 25.3—2019推荐值差异较大,是造成土壤风险控制值计算结果与GB 36600—2018的风险筛选值存在差异的主要因素。

流行病学调查是疾病早预防、早干预以及相关政策制定重要的科学依据。疾病前期(predisease)常指在流行病学调查/筛查中发现的机体非正常状态,但还没有达到疾病的诊断标准,是机体由健康状态向疾病状态进展的过渡阶段,如果不干预就会发展为疾病。如大家熟知的癌症前期(癌前病变)、糖尿病前期以及高血压前期等,也包括近视前期、青光眼前期以及糖尿病前期眼部并发症等眼病前期。疾病前期由于处于疾病尚未出现临床表现或者极早期阶段,通过适当的干预可以阻止甚至逆转疾病的发生而广受重视。然而,目前眼科工作者尚未对开展眼病前期流行病学调查足够重视,对如何开展眼病前期的流行病学调查也不甚了解,本文根据以往开展眼病流行病学调查的经验,就目前患病率高、视觉损伤大的几种常见眼病前期流行病学调查的开展进行论述。

数字时代政府由实体型向平台型转变、行政关系由封闭向开放转变、智慧行政越来越普遍,数字治理促进政府内部纵向、横向协调,政府以整体形象出现。行政组织法规范的重点应从分权、赋权、确权向行政机关之间的协助、配合转变以促进整体型治理。行政行为格式化、在线化、智慧化,数字治理让政府更强大,让行政证明更容易,有效控制行政权力成为行政行为法的首要任务,技术规范、技术标准等软法规则成为行政法的重要内容。数字治理改变传统行政管辖关系、启动程序及协助关系,行政程序法需规定行政机关之间数据共享、协同调查取证、协助审查判断证据、协同决策、协助执行等规则,减少行政程序证明对象,可以适当提高证明标准,将原由申请人承担的部分证明责任转移至行政机关。
