雅安地震中媒体的热报道与冷思考

雅安地震发生后,传统媒体进行了集中报道。报道在内容、时效性等方面都逐渐成熟。社交媒体也参与其中,并"异军突起"。但其中也存在部分媒体人专业素养较低、报道媚俗,以及微博中的混乱等问题。对此,应注重社交媒体的运用,加强媒体人素养的提高,并学习发达国家的灾难新闻报道方式。

Spatial variation of health risk of groundwater for drinking water supply in Mingshan County, Ya'an City, China

Rural drinking water safety is a growing concern in China. This study investigated the health risk of pollution of groundwater for the drinking water supply in Mingshan County, Ya'an City, in Sichuan Province, China, using 46 samples from the years 1991 to 2010. Carcinogenic, non-carcinogenic, and total risks were assessed by the model recommended by the United States Environmental Protection Agency (U.S. EPA). Thematic maps of the risks caused by single and multiple factors were generated from inverse distance weighting interpolation (IDW) and the geostatistical analysis functions of ArcGIS. The results show that the carcinogenic risks caused by chemicals in groundwater for drinking water supply are low, within the acceptable interval for risk management. However, non-carcinogenic risks are high and the number of sampling sites with risk values exceeding the standards amounted to 29. Non-carcinogenic risks of Cr6+, nitrate, fluoride, and Fe at sites 43, 46, 50, 64, 67, and 74 were the sources that caused high total health risk. This study reveals the risk level of groundwater quality and orders of treatment of pollutants, and provides a scientific basis for groundwater management in this area.
