The present work aims at giving a complete characteristic of the toxic chemical factor in the working environment of a pit "Kremikovtsi", for evaluating the occupational risk for the engaged workers. The basic pollution sources of the pit are the eliminating toxic gases during work from different types of machines and heavy-freight vans. The already measured concentrations of carbon monoxide, carbon dioxide, nitric oxides, hydrocarbons, aldehydes and lead, manganese, ferrous and mercury aerosols in all working places of the pit are under MAC. The calculated total index of toxicity for all working places surpasses up to 3 times the unit and is rated. 1st degree--unfavourable conditions of work concerning the toxic chemical factor.
本研究旨在全面描述“克雷米科夫齐”矿坑工作环境中的有毒化学因素，以评估从业工人的职业风险。该矿坑的主要污染源是作业期间各类机器和重型货车排放的有毒气体。该矿坑所有工作场所一氧化碳、二氧化碳、氮氧化物、碳氢化合物、醛类以及铅、锰、铁和汞气溶胶的已测浓度均低于最高容许浓度。所有工作场所计算得出的总毒性指数超过单位值达3倍之多，并被评定为1级——就有毒化学因素而言工作条件不利。
