韩媒称,韩国国内研究团队开发出了能实时掌握细颗粒物的构成成分的新监测系统。该监测系统能够一次掌握细颗粒物是否是从中国吹来的、并立即知道因成分不同而带来的细颗粒物的危险程度。今后更加精密的雾霾预报也有望实现。
据韩国《东亚日报》网站5月3日报道,光州科学技术院2日表示,地球?环境工学部的朴基洪教授组在国内首次成功开发出了能实时监测细颗粒物的构成成分的“浮质(空气中的悬浮微粒,如烟、雾等)质量分析系统”。
研究团队把激光控制技术与在实验室测定细微质量时利用的“离子质量分析技术”相结合,开发出了可以掌握空气中漂浮的微细粒子(烟雾剂)的成分的装置。从5年前开始研究烟雾剂成分分析的过程结束后,此次成功开发出了分析装备。研究团队计划将此次开发的装备小型化、产品化,并最终推进商用化。
为了查明细颗粒物的发生地区和原因、研究应对方法和环境影响评价等,很有必要知道细颗粒物的精确成分。能实时监测细颗粒物成分的装备虽然目前已被开发出来,但主要从海外进口。但其价格比较昂贵每台定价在5亿~6亿韩元左右,国内只昂引进了6台。如果除去研究用装备的话,用该设备进行实时测定的地方仅有两处而已。
朴教授说,“不仅是进口装备替代效果,连包括细颗粒物在内的、与国内浮质相关的研究的先进化也值得期待。”
此前韩国媒体曾报道称,中国的雾霾几乎不会对朝鲜半岛产生影响,北京的大气呈现停滞状况,雾霾不扩散。韩国环境部国立环境科学院预报员申东浩(音)表示,北京几乎没有风或吹些许东风,因此雾霾不太可能吹到朝鲜半岛,受中国雾霾的影响而在韩国出现可吸入颗粒物的概率非常小。
