[ citation needed ] Formalin when applied repeatedly (30–50 mg/L) kills infective theronts and tomonts but, due to its carcinogenicity, other chemotherapeutants should be used.
The symptoms suffered by Patterson’s guests are consistent with poisoning by death cap mushrooms, Thomas said, though toxicology reports are yet to show exactly what they consumed. ...
