The 2010-2011 wet season was one of extreme weather for the State of Queensland, Australia. Major rivers adjacent to the Great Barrier Reef (GBR) were discharging at rates 1.5 to >3 times higher than their long term median. Exposure to photosystem II herbicides has been routinely monitored over a period of up to 5 years at 12 inshore GBR sites. The influence of this wet season on exposure to photosystem II herbicides was examined in the context of this long-term monitoring record and during flood plume events in specific regions. Median exposures expressed as diuron equivalent concentration were an average factor of 2.3 times higher but mostly not significantly different (p<0.05) to the median for the long-term monitoring record. The herbicides metolachlor and tebuthiuron were frequently detected in flood plume waters at concentrations that reached or exceeded relevant water quality guidelines (by up to 4.5 times).
2010-2011 年的湿季是澳大利亚昆士兰州极端天气的一年。与大堡礁（GBR）相邻的主要河流的排放量是其长期中值的 1.5 至> 3 倍。在长达 5 年的时间里，在 12 个近岸 GBR 地点定期监测到对光合作用 II 除草剂的暴露。在长期监测记录的背景下以及在特定地区的洪水羽流事件中，研究了这个湿季对光合作用 II 除草剂暴露的影响。以敌草隆当量浓度表示的中位数暴露值平均高出 2.3 倍，但大多数情况下与长期监测记录的中位数没有显著差异（p<0.05）。在洪水羽流水中，经常检测到除草剂甲草胺和噻草隆，其浓度达到或超过相关水质指南（高达 4.5 倍）。
