Abstract The results of a study on occupational risks of a group of sewage workers in Genoa, Italy, are reported. The subjects were divided into three subgroups according to job characteristics. A questionnaire on individual symptoms, clinical examinations, blood and respiratory tests were administered. The relative risk of alterations in respiratory function (both instrumental and clinical findings) was increased among water treatment workers. Average platelet count in workers exposed to sewage appeared to be significantly reduced compared to non-exposed subjects although both were within normal limits. There was no evidence of an increased prevalence of positive A hepatitis markers in the exposed workers. Topics: case-control study; epidemiologic study; functional respiratory disorders; haematological changes; health hazards; risk factors; sanitation services; sewage treatment; symptoms; water treatment; work in sewers.
