[Occupational medicine in Desio: the hygiene and industrial toxicology laboratory--evolution of the activities in the last 10 years].

During last decade the analytical work of industrial toxicology and hygiene laboratory of the occupational medicine department of Desio Hospital (UOOML) developed towards more sophisticated and specialized techniques. This change required an updating and an increase of the analytical instruments and a continuous training of the laboratory staff, usually achieved by the incomes of the department. With this consideration in mind, we recognize the need for evaluating the laboratory activity by "indices" more susceptible of the qualitative aspect of the activity rather than the quantitative aspect.
