随着档案数据化趋势的日益增强,档案馆数据服务创新对于档案事业的持续发展愈发重要。档案数据故事化的发展可为大数据时代档案馆数据服务的改革创新提供新思路。在剖析档案数据故事化应用前景的基础上,结合档案馆用户的现实需求,进行档案数据故事化工作流设计,将档案馆数据故事化服务框架分为数据层、组织层、描述层和应用层并进行详细的业务流程分析,明确责任分工。现阶段档案馆开展数据故事化服务可能存在的问题和挑战有:数据处理失范、过分注重感官体验、缺乏专业技术支撑、媒介商业化扭曲数据本质等。档案数据故事化工作的开展应从以下几方面入手:规范化设计档案数据故事内容,合理选择档案数据故事呈现方式,多途径探索档案数据故事化相关技术,坚持档案数据社会效益的最大化。

高氯酸盐作为一种持久性新污染物,在环境和食品中存在,可能会对人体健康造成威胁.但目前中国粮食样品中高氯酸盐污染的研究有限,本研究从我国粮食主产区13个省份采集了271份粮食样品,包括稻谷样品88份,小麦样品83份,玉米样品100份,分析了这些样本中的高氯酸盐污染水平.结果表明稻谷中高氯酸盐浓度范围从未检出到66.41 ng·^g(−1),小麦中浓度范围为1.90—108.71 ng·^g(−1),玉米中浓度范围为0.31—45.52 ng·^g(−1).根据测得的高氯酸盐浓度,计算估计每日摄入量(EDI)和危害商(HQ),以评估人体通过食用大米、小麦和玉米接触高氯酸盐的潜在健康风险.大米、小麦和玉米的HQ值均小于1,说明食用这3种主食不会造成潜在的健康风险.然而,考虑到高氯酸盐的多种暴露途径,外加粮食的加工过程也可能会增加高氯酸盐污染,因此通过粮食摄入高氯酸盐对人体造成的暴露风险仍应当引起关注.

The exposure to perfluorinated compounds (PFCs) through the diet for humans is of great concern. Among the diet, dairy products are in great demand. This paper reports the study on the levels of 9 perfluorinated acids and 2 fluorotelomer acids in milk, milk powder and yoghurt purchased from Chinese markets from 2008 to 2009. The analytes were quantitated by high performance liquid chromatography/electrospray tandem mass spectrometry (HPLC-ESI-MS/MS). In milk samples, perfluoroheptanoic acid (PFHpA) and perfluorononanoic acid (PFNA) were detected frequently, both in 68% of samples. In milk powder samples, perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA) and PFNA were the only detected PFCs and none of them was observed in more than 35% of samples. In yoghurt, PFOA was the most frequently detected compound, found in 69% of samples. None of fluorotelomer acids was observed in any samples. The mean concentrations of total PFCs were 178 pg/g (wet weight) in milk, 98 pg/g (dry weight) in milk powder and 42 pg/g in yoghurt (wet weight). It is notable that the data of this study indicate significant differences (P<0.001) among three kinds of packaging of milk in the concentration of total PFCs. A preliminary human health risk assessment of milk and dairy products consumption was conducted in this study. For adults, the mean daily intake of PFOS and total PFCs was equal to or lower than 23 and 167 pg kg-1 d-1 (body weight), respectively.

Eleven perfluorinated compounds(PFCs) were determined in tissue samples from farmed pigs and chickens(n=143) that were purchased in Beijing in March *** total PFCs mean concentration was the highest in pig liver(3.438 ng g-1 wet weight(ww)),followed by pig kidney(0.508 ng g-1(ww)),pig heart(0.167 ng g-1(ww)),chicken liver(0.098 ng g-1(ww)),chicken heart(0.050 ng g-1(ww)),pork loin(0.018 ng g-1(ww)),and chicken breast(0.012 ng g-1(ww)).Among the PFCs analyzed,perfluorooctane sulfonate(PFOS) was the predominant compound in viscera and muscle of farmed pigs and *** addition,a strong linear correlation(r = 0.932) was observed between the concentrations of PFOS and perfluoroundecanoic acid(PFUnDA) in pig *** preliminary conclusion is that there is little potential risk of exposure to PFCs via the consumption of these products in Beijing.
