The components of the uncertainty of verification result were evaluated and calculated.

The expanded uncertainty of the verification result was 3.

It concludes that water content in ligroin's extract is more and more covariant with water polluted and Na_2SO_4 mat- ting thickness,but the testing result is still suitable for environment monitoring.
