[Acute poisoning of pigs with hydrogen sulfide as a result of acidification of slurry on a pig farm].
On a fattening pig farm all 582 animals died of peracute intoxication with hydrogen sulphide (H2S). The accident took place after 6000 litres of lactic acid (41.5 mass %) was dumped in the slurry pit. The volume of released gas was about 575 m3. This resulted in sudden spreading by high pressure of a lethal concentration of hydrogen sulphide to all compartments of the pig house. Analysis of the situation indicated that the level of hydrogen sulphide was 7870 ppm.
