Impact on human health of particulate matter emitted from burnings in the Brazilian Amazon region

OBJECTIVE: To analyze the impact on human health of exposure to particulate matter emitted from burnings in the Brazilian Amazon region. METHODS: This was an ecological study using an environmental exposure indicator presented as the percentage of annual hours (AH%) of PM2.5 above 80 μg/m3. The outcome variables were the rates of hospitalization due to respiratory disease among children, the elderly and the intermediate age group, and due to childbirth. Data were obtained from the National Space Research Institute and the Ministry of Health for all of the microregions of the Brazilian Amazon region, for the years 2004 and 2005. Multiple regression models for the outcome variables in relation to the predictive variable AH% of PM2.5 above 80 μg/m3 were analyzed. The Human Development Index (HDI) and mean number of complete blood counts per 100 inhabitants in the Brazilian Amazon region were the control variables in the regression analyses. RESULTS: The association of the exposure indicator (AH%) was higher for the elderly than for other age groups (β = 0.10). For each 1% increase in the exposure indicator there was an increase of 8% in child hospitalization, 10% in hospitalization of the elderly, and 5% for the intermediate age group, even after controlling for HDI and mean number of complete blood counts. No association was found between the AH% and hospitalization due to childbirth. CONCLUSIONS: The indicator of atmospheric pollution showed an association with occurrences of respiratory diseases in the Brazilian Amazon region, especially in the more vulnerable age groups. This indicator may be used to assess the effects of forest burning on human health.

Ambientes inclusivos na educação infantil: possibilidades e impedimentos

Este artigo discute os resultados de uma pesquisa realizada em uma escola municipal de Educação Infantil - EMEI - da cidade de São Paulo, que teve como objetivo identificar os indicadores de envolvimento no trabalho com as crianças e aqueles que determinam a construção de um ambiente inclusivo. A coleta de dados foi feita por meio de observações dos três estágios da Educação Infantil e do levantamento da documentação pedagógica. O trabalho com as diferenças apresenta contradições importantes de serem pensadas, que se expressam como desigualdades no tratamento junto às crianças. A concepção de inclusão se restringe ao atendimento de crianças deficientes, enquanto as necessidades das demais crianças e dos profissionais que trabalham na escola são muitas vezes desconsideradas. O isolamento e o envolvimento com questões marginais do trabalho pedagógico são pontos centrais a serem considerados no enfrentamento das barreiras atitudinais para a construção de um ambiente inclusivo.
