So, fewer cod and an explosion of zooplankton-eating sprats means more algae and less oxygen.

所以，鳕鱼数量减少，就造成了西鲱鱼增多，相应的就会消耗掉浮游动物，于是海藻增多，氧气减少。

To rapidly determine the pollution extent of wastewater, the potential of near infrared(NIR) spectroscopy for measurement of chemical oxygen demand(COD) in wastewater was investigated.

为快速确定废水的污染程度，研究了运用近红外光谱法测量废水化学需氧量（COD）的可行性。
