Caracterização microbiológica de lixiviados gerados por resíduos sólidos domiciliares e de services de saúde da cidade do rio de janeiro

Abstract

The present paper consisted on the microbiological characterization of leachate generated from solid waste from health services and municipal solid waste. This study aimed to support the discussion about the need for differentiated treatment and disposal for the health services solid waste. The following parameters were selected: total coliforms, thermotolerant coliforms, Escherichia coli, Enterococci, trials for Pseudomonas aeruginosa, and Salmonella and other Enterobacteria, analysis of susceptibility to antimicrobials and research on antimicrobial activity of the leachate. Expressive densities were observed in microbial populations in health services and municipal solid waste, with values ranging from 108 to 109. In both wastes, resistant and susceptible strains to antimicrobials occurred and none were resistant to all antibiotics tested. Results showed similarities for both types of waste and reinforce the recommendation for health services and municipal solid waste co-disposal in sanitary landfills.
