Abstract

The acute and subacute inhalation toxicity of a new Bulgarian antibiotic preparation "Bactericin" for plant protection is examined. It is meant for the treatment of seeds from tomatoes before sowing. The inhalational toxicity is evaluated by a complex of toxicometric, integral, behavioural, clinic-laboratory, biochemical and histological methods. The maximum concentration reached by dispersing is 40 mg.m-3. In the condition of acute (unrepeated exposure) and subacute (60 exposure) the concentration of 40 mg.m-3 causes no lethality, symptoms of intoxication and toxic effects in the organism of white rats therefore it could be accepted as not operative. The preparation conceals no danger of acute and chronic inhalational poisonings when working with the latter. On the basis of the performed investigations and bearing in mind, that the preparation is in the group of the antibiotics, a proposal is made for the purpose of orientation MAG in the air of the working zone -0.5 mg.m-3.

[植物保护用抗生素制剂Bactericin的吸入毒性研究]。
研究了保加利亚一种用于植物保护的新型抗生素制剂“细菌素”的急性和亚急性吸入毒性。它是用来在播种前处理番茄种子的。吸入毒性是通过综合毒性测量、积分、行为、临床实验室、生化和组织学方法来评估的。分散达到的最大浓度为40 mg.m-3。在急性(不重复暴露)和亚急性(60次暴露)条件下,浓度为40 mg。M-3对大鼠机体没有致死性、中毒症状和毒性作用,因此可以接受为无效。当使用后者时,该制剂不会隐藏急性和慢性吸入性中毒的危险。在进行调查的基础上,考虑到该制剂属于抗生素组,建议在工作区空气中定向MAG -0.5 mg.m-3。
