项目摘要

Emissions of air pollutants from all possible sources during RSS (Ribbed Smoke Sheet) production, transportation inside Thailand, or, transportation of tapped latex with motorcycles, tracks to RSS storage centers and ports, shipping to Japan and rubber tire production in Japan were evaluated based information from related data including LCA data base and the measurement of pollutants on emission sources, showing more than 30% of PAHs is emitted inside Thailand, mostly from the drying process. Clear relations between RSS production amount and ambient PAHs concentration were found to exist: maximum PAHs concentration was observed at maximum RSS production during rainy season, which is about 7-8 times larger than a back ground value. The wind direction was found to have an importance on PAHs concentration: the lowest concentration in Hat Yai for the largest RSS production amount from January to February when the northeast or east wind from Gulf of Thailand is predominant. A clear dependen … More cy of an index for biomass burning was observed in relation to RSS production except January and February. The irradiation of soft X-rays can degrade effectively PAHs in smoke particles from rubber wood burning, where more PAHs was effectively degraded in finer fraction of particles. An electrostatic precipitator was tested and proven to improve the quality of products by reducing smoke particles. Most concern of works was confirmed to be in smoke through interview. Concentrations of gaseous pollutants such as NO_2 and SO_2 in the workplace of RSS factory were rather low while PAHs concentration is quite high, where more than a few hundred ng/m^3 of PAHs were observed. This may be mostly from a smoke leakage from drying room. 1-OHP (Hydorxine pyrene) increased with PM concentration while a tendency between Pyrene and 1-OHP concentrations was not clear. Sediment samples were collected from a lake in Trang province, which provide information on a history of environmental change after RSS production was started 100 years ago. Less

在RSS(罗纹烟片)生产、泰国境内的运输、或摩托车运输、RSS储存中心和港口的轨道、运往日本和日本的橡胶轮胎生产过程中，所有可能来源的空气污染物的排放量都进行了评估，评估的依据是相关数据，包括LCA数据库和对排放源污染物的测量，显示超过30%的多环芳烃是在泰国境内排放的，主要来自干燥过程。RSS产生量与环境PAHs浓度之间存在明显的关系：雨季RSS产生量最大时PAHs浓度最大，约为背景值的7~8倍。风向对多环芳烃的浓度有重要影响：1-2月，泰国湾的东北风或东风占主导地位，Hat Yai的浓度最低，RSS产生量最大。一个明确依赖的…除1月和2月外，与RSS产量相关的生物质燃烧指数的周期数较多。软X射线辐照可以有效地降解橡胶木材燃烧产生的烟雾颗粒物中的多环芳烃，其中更多的多环芳烃被有效地降解在更细小的颗粒中。试验证明，电除尘器通过减少烟尘颗粒，提高了产品质量。采访证实，最受关注的作品已经烟消云散。RSS厂车间内NO2、SO2等气态污染物浓度较低，而多环芳烃浓度较高，可达数百ng/m~3以上。这可能主要是由于干燥室冒烟造成的。1-羟基苯并(1-OHP)浓度随PM浓度的增加而增加，但与1-OHP浓度的变化趋势不明显。沉积物样本采集自庄省的一个湖泊，提供了100年前开始生产RSS后环境变化历史的信息。较少
