Abstract:
Objective To study the acute inhalation toxicity of 50% Luowei,a plant molluscacide,in rats. Methods Twenty adult Wistar rats,half male and half female,were given of 5000 mg/m3 of 50% Luowei through a dynamic inhalation de?vice and the death and recovery of the rats were observed within 14 days,and LC50 was drawn. Results After exposure,the ac?tivities of the rats decreased and a few individual animals had scratching symptom,but the symptom disappeared after the expo?sure. No animals died during the whole observation period. Therefore,the acute inhalation LC50 was greater than 5000 mg/m3 for rats,and Luowei belonged to low toxicity level. Conclusions 50% Luowei will not cause animal death if it is inhaled into ani?mal body. However,people still need to wear protective equipment in production and use.
