The Poisons Information Centre at the Department of Toxicology gives toxicological information every day for full 24 hours. The information is based on the file of chemical compounds and substances. Each telephone enquiry is recorded and then analysed by the staff of Poisons Information Centre. The toxicological information covers children, adults and mass-poisonings cases, Most of the enquires concern consultation, then information and last consultation and information. During the regular telephone service most enquires are made about drug poisonings, ethanol, pesticides and mushrooms. Most of the enquiries are made by physicians. Private persons come next. Further activity of Poisons Information Centre depends on the access to the world literature and popularisation of toxicological knowledge among the people. This will contribute to higher rate toxicological enquires from private persons.
