abstract: The production of synthetic rubber, one of the varieties of petro-chemical branch in our country, is new and very prospective. The Bulgarian synthetic rubber is synthesized from petroleum products divinyl and styrene. After the hygienic assessment of the technological processes, a complete characteristic of labour conditions was made and the character of the working process was studied of the main occupations of the workers, attending the installations of Synthetic Rubber Plant. The exposure to occupational noxae was determined and the existing occupational risk was evaluated. The toxico-chemical substances, benzene, styrene and divenyl, are with the highest significance among the factors of the working environment. The data on the health state of the workers are reported and recommendations are proposed for the restriction of the effect of the occupational factors.
