AVALIAÇÃO SANITÁRIA DE RESÍDUOS SÓLIDOS ORGÂNICOS DOMICILIARES EM MUNICÍPIOS DO SEMIÁRIDO PARAIBANO

Abstract

The goals of this work consisted of identifying the prevalence of helminth eggs in household organic wastes generated in the urban zone of cities of the semiarid of the Paraíba. The work was accomplished from June to December of 2006 in 30 homes in the urban center of Cabaceiras, 30 in Caraúbas and 50 in Queimadas. Organic solid residues were collected during in three consecutive weeks and alternate days (Monday, Wednesday and Friday) in the generating source. For quantification of the helminth eggs three composed samples were picked up by city, resultants of ten fractions of organic solid residues collected in the homes. The amount of helminth eggs varied from 12.82 to 14.39 eggs/gST, with viability of 95.42%. In prevalence order, they enrolled Ancylostoma sp., Enterobius vermiculares, Fasciola hepatica and Ascaris lumbricoides. The eggs of Ancylostoma sp. were identified in 100% of the examined samples. The terrible sanitary quality verified for the household organic waste solid in three cities, located geographically in the area of the paraiban semiarid they suggest that these residues constitute important source of contamination to the environment and the human being, requesting the appropriate management.
