5 other workers were also exposed and suffered from similar effects like
nausea, vomiting and dizziness; burning sensation of the nose,
irritation of the eyes, diminished vision, numbness of hand and fingers;
reduced blood pressure;
recovery within hours or weeks.
Exposure: in experiments using a closed chamber comparable to the
conditions in the shed (but reduced to 5 m³) in the firm above potatoes
were exposed and concentration measured: peak after ca. 4 h at 3300 ppm,
rapid drop to ca. 400 ppm (constant for 140 h).
In agricultural firms the test substance was used to accelerate
sprouting of potatoes. Workers were repeatedly exposed via the dermal
and inhaltion route. Clinical signs and the data on a fatality
(presumably after acute exposure to high dose levels) indicated effects
on nervous, hepatic, renal and vascular system. Experimental data
suggested inhalation exposure levels up to 3300 ppm but in most cases
workers might be exposed to 400 ppm.
Conclusion: Death of one and the illness of five workers exposed via
inhalation and/or dermal route; effects on nervous, hepatic, renal and
