( 2 )由于受纳污染物类型和总量上的差异，香花桥镇水网中小河流氮磷污染程度还存在明显的空间分异：居民区附近的小河流受nh _ 4 ~ +和p的污染很重；主要受纳农田径流的小河流， nh _ 4 ~ +和p的污染较轻，但受no _ 3 ~ -污染的风险加大；养殖场附近的小河流， nh _ 4 ~ +和p常有突发性暴增的现象。 - Taking the lab to the river dr baker adds : " traditionally tests are lab - based and take up to five days . it is crucial that water samples dont degrade in the time that it takes to transport them from the river to the lab , so we wanted to develop a device that can be taken to the river bank so that water samples can be examined immediately we can now take a sample , measure the fluorescence and identify the pollutants
至关重要的是，要确保水样在从河边送到实验室的过程中，水质不会发生变化。所以我们希望能够开发出一种可以放置在河边，并能够立即对水样进行检测的设备。现在我们能够抽取水样、检测荧光并鉴别污染物类型。
