| description | Objective: This study aims to identify the scientific evidence on the risks and effects of exposure to environmental contaminants in children during sensitive developmental periods. Data source: The search was performed in the Bireme database, using the terms: children's health, environmental exposure, health vulnerability, toxicity pathways and developmental disabilities in the LILACS, MEDLINE and SciELO systems. Data synthesis: Children differ from adults in their unique physiological and behavioral characteristics and the potential exposure to risks caused by several threats in the environment. Exposure to toxic agents is analyzed through toxicokinetic processes in the several systems and organs during the sensitive phases of child development. The caused effects are reflected in the increased prevalence of congenital malformations, diarrhea, asthma, cancer, endocrine and neurological disorders, among others, with negative impacts throughout adult life. Conclusion: To identify the causes and understand the mechanisms involved in the genesis of these diseases is a challenge for science, as there is still a lack of knowledge on children's susceptibility to many environmental contaminants. Prevention policies and more research on child environmental health, improving the recording and surveillance of environmental risks to children's health, should be an ongoing priority in the public health field. Resumo: Objetivo: O presente estudo busca identificar as evidências científicas sobre os riscos e efeitos da exposição de contaminantes ambientais no organismo infantil durante os períodos sensíveis de seu desenvolvimento. Fonte de dados: As pesquisas foram realizadas pelo banco de dados da Bireme, com os termos children's health, environmental exposure, health vulnerability, toxicity pathways and developmental disabilities nos sistemas LILACS, MEDLINE e SciELO. Síntese de dados: A criança difere do adulto por suas características singulares de ordem fisiológica, comportamental e do potencial de exposição a riscos frente às diversas ameaças do ambiente. A exposição a agentes tóxicos é analisada por meio dos processos toxicocinéticos nos diversos sistemas e órgãos durante as janelas sensíveis do desenvolvimento infantil. Os efeitos causados transparecem no aumento da prevalência de malformações congênitas, diarreia, asma, cânceres, distúrbios endócrinos e neurológicos, entre outros, com impactos negativos ao longo da vida adulta. Conclusão: Identificar as causas e compreender os mecanismos envolvidos na gênese desses agravos é um desafio que se impõe à ciência, visto que ainda há uma lacuna de conhecimento sobre a suscetibilidade infantil para muitos contaminantes ambientais. Políticas de prevenção e mais pesquisas em saúde ambiental infantil, que impulsionem o registro e a vigilância epidemiológica dos riscos ambientais à saúde da criança, deve ser uma prioridade contínua no campo da saúde pública.
