“…In addition, this practice can damage the health of the resident population in the vicinity, making them more susceptible to diseases, above all respiratory ones [18,19]. A larger number of people can be subject to its effects in the event that the dominant winds are directed towards more densely populated areas [20] since many urban areas are typically located next to sugarcane cultivated areas as well as ethanol and bioelectricity plants.…”

Sugarcane is an important crop for the Brazilian economy and roughly 50% of its production is used to produce ethanol. However, the common practice of pre-harvest burning of sugarcane straw emits particulate material, greenhouse gases, and tropospheric ozone precursors to the atmosphere. Even with policies to eliminate the practice of pre-harvest sugarcane burning in the near future, there is still significant environmental damage. Thus, the generation of reliable inventories of emissions due to this activity is crucial in order to assess their environmental impact. Nevertheless, the official Brazilian emissions inventory does not presently include the contribution from pre-harvest sugarcane burning. In this context, this work aims to determine sugarcane straw burning emission factors for some trace gases and particulate material smaller than 2.5 μm in the laboratory. Excess mixing ratios for CO 2 , CO, NO X , UHC (unburned hydrocarbons), and PM 2.5 were OPEN ACCESSAtmosphere 2012, 3 165 measured, allowing the estimation of their respective emission factors. Average estimated values for emission factors (g kg −1 of burned dry biomass) were 1,303 ± 218 for CO 2 , 65 ± 14 for CO, 1.5 ± 0.4 for NO X , 16 ± 6 for UHC, and 2.6 ± 1.6 for PM 2.5 . These emission factors can be used to generate more realistic emission inventories and therefore improve the results of air quality models.

“…A origem, a composição química e o tamanho dessas partículas definem os seus efeitos sobre a saúde humana. As partículas mais lesivas são as PM 2.5 (Particulate Matter), assim denominadas em virtude de sua dimensão física (Ribeiro;Assunção, 2002). No norte de Mato Grosso, essas partículas eram produzidas principalmente no período da seca, entre julho e outubro (Artaxo et al, 2005).…”

Resumo As transformações mais profundas nos ecossistemas amazônicos foram produzidas pela expansão da fronteira agrícola. No norte de Mato Grosso, esse fenômeno contribuiu com a derrubada e queima de mais de 50% da floresta nativa. Os ecossistemas aquáticos foram contaminados com agrotóxicos e mercúrio. Objetivamos compreender como se comportou a saúde da população local em função dessas alterações ambientais. Trata-se de um estudo de caso, fundamentado pelos pilares da ecossaúde: transdisciplinaridade, participação social e equidade de gênero. Os resultados sugerem que, na fronteira agrícola amazônica de Mato Grosso, a degradação e a contaminação dos ecossistemas estão relacionadas à emergência de novas doenças. A crescente abertura da fronteira ao mercado global consolida a geração de riscos industriais, contribuindo com o aumento da incidência de doenças cronico degenerativas.

“…3 Estudos têm indicado que a emissão de poluentes da queima da cana pré corte é importante fonte para formação de ozônio, 4-6 além de produzir efeitos nocivos na saúde da população. [7][8][9] No processo de queima da cana pré corte foram identificadas substâncias precursoras de ozônio, como compostos aromáticos, compostos carbonílicos, áci-dos carboxílicos e óxidos de nitrogênio (NOx). Em estudo de Lopes,10 formaldeído e acetaldeído foram os carbonílicos mais abundantes em emissões de queima da cana com concentrações entre 2,9 a 60 ppb; em termos de fator de emissão (quantidade de substância emitida por massa de cana queimada) a variação foi de 44,8 a 524 mg kg -1 .…”

“…The association between pre-harvesting sugarcane burning and its effects on health has been demonstrated by several authors [7][8][9][10][11][12][13][14] and by different methods, but such agricultural practice still persists. For about 60 years, this pollution has been impacting the health of the State's population.…”

ABSTRACT:After 2003, a new period of expansion of the sugarcane culture began in Brazil. Pre-harvesting burning of sugarcane straw is an agricultural practice that, despite the nuisance for the population and pollution generated, still persisted in over 70% of the municipalities of São Paulo State in 2010. In order to study the distribution of this risk factor, an ecological epidemiological study was conducted associating the rates of deaths and hospital admissions for respiratory diseases, for each municipality in the State, with the exposure to the pre-harvesting burning of sugarcane straw. A Bayesian multivariate regression model, controlled for the possible effects of socioeconomic and climate (temperature, humidity, and rainfall) variations, has been used. The effect on health was measured by the standardized mortality and morbidity ratio. The measures of exposure to the pre-harvesting burning used were: percentage of the area of sugarcane harvested with burning, average levels of aerosol, and number of outbreaks of burning. The autocorrelation between data was controlled using a neighborhood matrix. It was observed that the increase in the number of outbreaks of burning was significantly associated with higher rates of hospital admissions for respiratory disease in children under five years old. Pre-harvesting burning of sugarcane effectively imposes risk to population health and therefore it should be eliminated.

“…The quality of the soil (red earth) and climate make it one of the leading agricultural areas in the State of São Paulo and Brazil as a whole, characterized by thriving farm production and high crop yields, especially for sugarcane, making the region the world's largest producer of sugar and alcohol. As a result, Ribeirão Preto suffers from intense environmental degradation due to burning of the cane fields by the sugarcane industry, which is extremely harmful to health 18,19 and identified as the principal source of air pollution.…”
