Abstract

This paper describes an alternative method to assess atmospheric pollution levels caused by the burning of sugar cane fields during the harvest, affecting visibility in nearby residential areas. The samples of atmospheric dispersed material were taken on glass slides exposed to the environment on different periods of time. The scattered light by these samples is measured using a digital goniometric device that moves a CCD around each sample with 2,0 arc min resolution. Scattering measurements reveals that it is possible to differentiate between the samples of 12, 24, 36 and 48 hours of integration. This method is more sensitive because it integrates through time, even when the concentrations of contaminants are low. Based on Beer-Lambert scattering model, the scattered light on the samples is related to the atmospheric extinction coefficient and the meteorological visibility measured in the same days. A good linear correlation for the different time periods (R2 > 0.94)was obtained. Finally, measured scattering levels were compared to the intraocular scattering ones calculated from CIE equation, obtaining similar values to eyes of 80 years old people

评估甘蔗种植园生物质燃烧造成的空气污染的替代方法

本文描述了一种替代方法来评估甘蔗收获期间燃烧甘蔗田造成的大气污染水平，影响附近居民区的能见度。在不同时间暴露于环境中的玻片上采集了大气分散材料的样本。这些样品的散射光是用一个数字测角装置测量的，该装置在每个样品周围移动一个CCD，分辨率为每小时2角。散射测量表明，可以区分12、24、36和48小时积分的样品。这种方法更敏感，因为它可以随时间变化而变化，即使污染物浓度很低。基于Beer-Lambert散射模型，样品上的散射光与大气消光系数和当天测得的气象能见度有关。不同时间段间均有良好的线性相关(R2 > 0.94)。最后，将测量的散射水平与CIE方程计算的眼内散射水平进行比较，得到与80岁老人眼睛相似的值
