While the storage facilities were emptied of pesticide stocks, the state of these storehouses remained a problem. The environment within these premises was contaminated and some of them are partially damaged. Until its closure in 1990 the plant produced sodium dichromate for leather tanning, pesticides such as lindane (gamma-HCH) and thiram. Pollution from these processes heavily contaminated an area that includes the former plant, a nearby dumpsite and abandoned chemical storage facilities.
