A poluição do ar e o sistema respiratório

Abstract: Over the past 250 years-since the Industrial Revolution accelerated the process of pollutant emission, which, until then, had been limited to the domestic use of fuels (mineral and vegetal) and intermittent volcanic emissions-air pollution has been present in various scenarios. Today, approximately 50% of the people in the world live in cities and urban areas and are exposed to progressively higher levels of air pollutants. This is a non-systematic review on the different types and sources of air pollutants, a… Show more

“…The sugarcane green harvest system (characterized by the absence of crop burning, with mechanized harvest and residue deposition on the soil surface, especially leaves and culms), which has replaced the pre-harvest burning method, has increased in use in Brazil since the 1990s due to increased awareness of environmental impacts, such as the increase in gas emissions that cause the greenhouse effect and emissions of particulate matter that have a harmful impact on human health (Arbex et al, 2012;Sisenando et al, 2012). The sugarcane green harvest system promotes soil protection by the deposition of larger quantities of straw (average 10 to 30 Mg ha -1 ) which provides higher C accumulation in the soil, leading to a positive CO 2 balance (Razafimbelo et al, 2006) as the C that would be emitted directly by burning remains in the system, it can be incorporated into the soil, favoring microbiota (Panosso et al, 2011).…”

“…Devido à grande área de contato entre a superfície do sistema respiratório e o meio ambiente, a qualidade do ar interfere diretamente na saúde respiratória (ARBEX, 2012). Para o Brasil, estima que a poluição atmosférica possa causar cerca de 20 mil óbitos/ano, valor cinco vezes superior ao número de óbitos estimado pelo tabagismo ambiental/passivo, e 10,7 mil óbitos/ano decorrentes da poluição do ar em ambientes internos (OMS, 2009).…”

“…A rápida urbanização verificada em todo o planeta trouxe um grande aumento no consumo de energia e também de emissões de poluentes provenientes da queima de combustíveis fósseis por fontes fixas, como as indústrias, e por fontes móveis, como os veículos automotores (ARBEX, 2012).…”

“…Com isso, há aumento significativo nos casos de pneumonia, asma e bronquite (6,7) . Estudo realizado com crianças na região de São Paulo entre mortalidade por doenças respiratórias e a relação com umidade, temperatura e poluentes ambientais mostrou que houve uma associação significativa e um aumento de cerca de 20% no atendimento emergencial das doenças respiratórias (8) . Baseado no exposto, o presente trabalho tem por objetivo avaliar a relação entre variáveis meteorológicas e doenças respiratórias por faixa etária.…”
