As these data indicate, the number of chemical spills reported is relatively constant over time.
The ENS data contains information on the incident as reported and with follow up investigative information when available, the material and amount involved in the incident, and the details for the vehicle involved in the incident (i.e., vessel, train and other mobile units).
These data have been used in a variety of studies assessing hazardous chemical releases, including case studies. Green criminologists (Lynch, Stretesky and Hammond, 2000) have used these data to examine the media coverage of these incidents, and the compare media coverage of chemical crimes to media coverage of street crime.
