("广东近海污染超标，不少海鲜重金属严重超标，其中生蚝中铜和镉分别超标740倍和90倍")
Note:
(a) The report is based on old news:
苏稻香, 2010广东海洋环境质量公报:近4成入海排污口超标排放.南方日报, July 29, 2011

("昨日，由广东省海洋与渔业局发布的《2010年广东省海洋环境质量公报》透露")
The above sounds innocuous. HOWEVER, apparently 羊城晚报 recently got its hand on 海洋公报 itself and reports today about heavy metals in oyster, which BBC further disseminates.
