Explanation of novelty and usefulness: 

In this article, a discovery was made: a new type of environmental hazard, new type of toxicity of a synthetic chemical (a cationic surfactant), water pollutant. At a low concentration in water, this chemical was toxic to a common species of zooplankton, namely, a rotifer. 

The chemical decreased the feeding rate of the rotifers. The result of this is a damage to aquatic ecosystem health.

In short, discovery of negative effects of the cationic surfactant tetradecyltrimethylammonium bromide (TDTMA) on filtration rate and feeding rate of the rotifer, Brachionus calyciflorus;
