Objetivo: Avaliar os teores de mercurio na urina dos graduandos de Odontologia do Centro de Ensino Superior do Estado do Para (CESUPA) em 2002. Metodo: Avaliados os teores de mercurio na urina de 20 alunos, atraves da espectofotometria de absorcao atomica. Resultados: Analise estatistica constatou que nao houve indicios de exposicao ocupacional; 80% dos alunos estavam com teores de mercurio dentro dos limites de normalidade (10µg/L) e apenas 4 encontravam-se acima do limite de normalidade, porem, dentro do limite maximo tolerado (50µg/L). Conclusao: Os teores de mercurio na urina de 80% dos graduandos de Odontologia encontram-se dentro do limite de normalidade (10µg/L) e, 20% dentro do limite biologico maximo tolerado (50µg/L) preconizado pela OMS, de acordo com a NR7.
