Purpose: analyze the impact of temporal auditory processing in writing and phonology of children with lead poisoning. Method: this study included 24 children, both genders, with a blood lead level equal or higher than 10pg/dL, without hearing impairment. Were assessments the spontaneous writing, immediate auditory memory, auditory discrimination, phonological awareness and auditory processing screening. Were assessments the spontaneous writing, immediate auditory memory, auditory discrimination, phonological awareness and auditory processing screening. Children were divided in two groups (GE--children with exchange of the consonant surd by sound in writing, GC--children without alterations in writing). Results: in GE, eight children (67%) had results abnormal in auditory discrimination and in PCF, the not expected performance in the AFT-R (subtest 1). In GC, only one child (8%) had results abnormal in auditory discrimination, and in PCF; the not expected performance in AFT-R (subtest 1). Fisher's Exact Test indicated significant difference between groups in the skills of auditory memory and auditory discrimination. Conclusion: there was no significant difference between performances in screening of temporal auditory processing in the groups. Children contaminated by lead and alterations in writing had worst performance in tests of phonological awareness, auditory discrimination, auditory memory. KEYWORDS: Lead; Hearing; Child; Memory; Speech, Language and Hearing Sciences Objetivos: analisar o impacto das habilidades do processamento auditivo temporal e da fonologia na escrita de criancas contaminadas por chumbo. Metodo: participaram deste estudo 24 criancas de ambos os generos, com nivel de plumbemia igual ou superior a 10 [micro]g/dL, sem alteracoes auditivas. Foram avaliados escrita espontanea, memoria auditiva imediata, discriminacao auditiva, consciencia fonologica e feita triagem do processamento auditivo temporal. As criancas foram divididas em dois grupos (GE--criancas com trocas de consoante surda por sonora na escrita; GC-- criancas sem alteracoes na escrita). Resultados: no GE, 8 criancas (67%) apresentaram alteracao de discriminacao auditiva, na PCF e desempenho nao esperado no AFT-R (Subteste 1). No GC, apenas 1 crianca (8%) apresentou alteracao de discriminacao auditiva e na PCF e desempenho nao esperado no AFT-R (Subteste 1). O Teste Exato de Fisher indicou diferenca significante entre os grupos nas habilidades de memoria auditiva e discriminacao auditiva. Conclusao: nao houve diferenca significante entre o desempenho na triagem do processamento auditivo temporal nos grupos avaliados. As criancas contaminadas pelo chumbo que apresentaram alteracao de escrita obtiveram pior desempenho nas provas de consciencia fonologica, discriminacao auditiva, memoria auditiva imediata.
