***General Introduction*** 
This dataset contains data collected from a 39-day experiment in which a set of macrophyte- dominated freshwater indoor systems were employed: doi:10.4121/uuid:804cbaa6-95ec-4c28-829f-87ba0344a554 
The experiment was conducted in Institute of Pesticides and Environmental Toxicology, College of Agriculture and Biotechnology, Huajiachi Campus, Zhejiang UniversityThis research project was made possible by a grant from the China Scholarship Council (CSC). 
***Purpose of the test campaign*** 
The purpose of the experiment was to quantify relationship between state of biomarker (inherent activity of ChE, apparent activity of ChE, immuno-reactive content of NAGase, and activity of NAGase) and that of population 
***Test equipment*** 
Shimadzu GC-2010 Plus (equipped with a ECD)
GEMINI XPS fluorescence microplate reader
VERSA max microplate reader, etc.
***Description of the data in this data set*** 
Figure 3: Change in population of Daphnia magna in chlorpyrifos expoxure.
Figure 6: Change in somatic ChE (inherent activity and apparent activity) in D. magna in chlorpyrifos exposure.
Figure 9: Change in immuno-reactive content and activity of NAGase in media.
