And also, the deterrence has enhanced by this modification. But, the criminal law amendment has not only given the criteria of the serious pollution of the environment, but also explicitly given the range of “hazardous substances”. Besides, the sentencing of the crime is also unreasonable. Therefore, there are still many missings in this modification. It is necessary to remedy of the missings by the way of judicial interpretation.
