| Abstract: | Two cases of fatal hydrogen sulfide poisoning are described which occurred during cleaning of a tank that had transported polysulfides. The most characteristic findings of the autopsy were: a blackish-green pigmentation at macroscopic examination; pulmonary edema, steatosis, intrahepatic cholestasis and renal tubular necrosis at microscopic examination. The blood concentration of sulfide ions exceeded 3.5 mg/l. These cases are compared to others described in the literature. The preventive measures that should be adopted to avoid this type of poisoning are stressed. |
