今天，人民网科技频道再次伙同农官为转基因商业利益散布虚假信息，还搞上了造谣诽谤活动。如下：
人民网科技：(网上的说法)，今年1月，美国官方发布公告，二次确认转基因作物商业化使美国主要水源河流发生足够严重的污染，其中转基因作物种植使用区域的污染尤其足够严重。公告说，自转基因作物商业化以来，化工农草甘膦用量增加数倍。不知道几位专家是否认同这一观点?[14:08]。
彭于发(中国农业科学院植物保护研究所研究员)：根本就没有看到这样的公告，不存在这样的公告。所谓转基因作物能污染周边的环境也是一个谣言，仔细查一下这个说法的来源是某一个人的博客在网络上断章取义、编造的一个谣言。转基因作物发展17年的历史，事实上看来，与种植常规作物防止病虫害相比，种植转基因作物不仅减少了农药用量和危害，而且对生态环境是有益的。[14:10]
事实：所谓该官方公告“来源是某一个人的博客”，那就是本人的日志空间。那官媒官员的说法，是滥用职权对本人搞诽谤活动。请看事实，下面就是美国的官方公告原文：
Technical Announcement: Widely Used Herbicide Commonly Found in Rain and Streams in the Mississippi River Basin。
Released: 8/29/2011 8:19:35 AM。
URL：http://www.usgs.gov/newsroom/article.asp?ID=2909 。
Glyphosate, also known by its tradename Roundup, is commonly found in rain and rivers in agricultural areas in the Mississippi River watershed, according to two new USGS studies released this month.
Glyphosate is used in almost all agricultural and urban areas of the United States. The greatest glyphosate use is in the Mississippi River basin,where most applications are for weed control on genetically-modified corn, soybeans and cotton. Overall, agricultural use of glyphosate has increased from less than 11,000 tons in 1992 to more than 88,000 tons in 2007.
"Though glyphosate is the mostly widely used herbicide in the world, we know very little about its long term effects to the environment," says Paul Capel, USGS chemist and an author on this study. "This study is one of the first to document the consistent occurrence of this chemical in streams, rain and air throughout the growing season. This is crucial information for understanding where management efforts for this chemical would best be focused."
In these studies, Glyphosate was frequently detected in surface waters, rain and air in areas where it is heavily used in the basin. The consistent occurrence of glyphosate in streams and air indicates its transport from its point of use into the broader environment. (摘录完)。
那公告是美国联邦官方机构发布的。它清楚说明：转基因作物种植，[1] 给美国农区水系带来了污染; [2] 使农药用量大幅增加，譬如，草甘磷用量，从1992年的少于11,000吨、增加到2007年的多于88,000吨(15年里，转基因作物种植使仅仅草甘磷农药用量的增加幅度就达到了800%)。
对比事实，人民网科技频道和农官彭于发自己才是搞了造谣活动。他们说本人“编造谣言”，那是滥用官权而对本人搞公开的诽谤活动。
若中国相关国家部门还有起码自尊，就请对你们的官媒和官员为转基因商业利益而不择手段的造谣诽谤行为，做做起码的管制吧。
