text: Concentrations of 100 to 200 parts per million for one to eight hours may cause sleeplessness, blurred vision, haemorrhage and death.
text: For example, small amounts of hydrogen sulfide can be metabolized, but higher concentrations can quickly cause death from respiratory paralysis.
text: Higher concentrations will cause severe breathing difficulty, conjunctivitis, pulmonary edema, and even death.
text: Nevertheless, the overall magnitude of this effect was relatively small, resulting in an approximately 2-fold decrease of LC 50 values (i.e., concentration expected to cause death in 50% of test animals) over the pH range of 7.5 to 8.5.
