Faculty of Public Health. Department of Occupational Health and SafetyThis study was conducted in a battery manufacturing plant where lead was used in the processes of production, to survey the working conditions and safety behaviors, and to measure the airborne lead level contaminated in the workplace and the blood lead level of workers. The survey of working conditions showed that the workers were directly exposed to lead in sections e.g. grid casting, spreading, forming and polishing, assembly and special battery production sections. Some workers in these sections used a cotton mask to protect dust exposure, but most workers did not use any masks. High airborne lead level more than 0.2 mg/m3 was frequently measured in these sections. Geometric average of blood lead level slightly increased from 17.9 µg/dl to 22.3 µg/dl during 1998 and 2001. However, the geometric average of blood lead level dropped to 17.4 µg/dl in 2002. No workers had blood lead level above 60 µg/dl. Workers with different age groups had no significantly different average blood lead level. Workers whose duration of work was between 20-29 years had average blood lead level of 21.5 µg/dl. This group of workers had slightly higher blood lead level than those whose duration of work was 19 years or less, but with no significant difference. 21 subjects underwent annual health examination and exposure monitoring in 2002. There was no significant relation between airborne lead level and blood lead level.Publication Open Access Spatial distribution of potentially toxic trace elements of agricultural soils in the lower central plain of Thailand after the 2011 flood(2014-06) Aksarapak Pongpom; Kampanad Bhaktikul; Worachart Wisawapipat; Piyakarn Teartisup; Kampanad Bhaktikul; Mahidol University.

Faculty of Environment and Natural Resource StudiesThe objective of this research is to study the concentration of ambient TSP and PM10 at aerobic exercise sites in public parks of the Bangkok Metropolitan Administration, Thailand. TSP and PM10 samples were collected during the rainy season, from September 2009 to October 2009 and during the winter season, from January 2010 to February 2010 using high volume air samplers. The samples were collected from five sites in four public parks: Lumphini (two sampling sites), Suan Luang Rama 9, Benchasiri, and Saranrom. The results showed that all 162 samples of 24-hour average TSP and PM10 concentrations were lower than Thailand’s ambient air quality standards. Concentration levels of TSP at Lumphini 1, Lumphini 2, Suan Luang Rama 9, Benchasiri, and Saranrom in the rainy season varied from 34.1–55.6, 26.6–42.9, 33.7–78.2, 42.0–83.6, and 43.9–73.7 μg/m3 respectively, and in the winter season from81.8–124.2, 75.2– 118.9, 36.9–113.0, 47.6–125.0, and 56.4–139.9 μg/m3 respectively. Levels of PM10 in the rainy season varied from 17.5–28.1, 10.4–20.5, 23.4–55.2, 22.2–49.0, and 31.0–60.0 μg/m3 respectively, and in the winter season from 51.1–82.7, 42.0–71.2, 20.8–74.9, 27.3–90.6, and 37.0–110.2 μg/m3 respectively. Furthermore, there was a statistical significant correlation between TSP and PM10 concentrations at four of the five sampling sites during both the rainy and winter seasons (p < 0.05), except for at Saranrom which showed no statistical significant correlation during the rainy season. In addition, levels of particulate matter at the two Lumphini sites in the winter season were significantly higher than in the rainy season; whereas at the other three parks, levels of particulate matter were not statistically significantly different betweenPublication Open Access Lime and Lignite Fly Ash as cement replacement in hazardous waste solidification process: Case study of spent fluorescent lamp(2009-12) Petcharat Jekjuntuk; Chumporn Yuwaree; Gritsanaruk Theeraraj; Rungjarat Hutacharoen; Jirapun Chotiratanarak; Mahidol University. Faculty of Environment and Natural Resource StudiesThe main objective of this research is aimed at the usage of lignite fly ash (power plant) and lime as cement replacement in hazardous - waste solidification process of spent fluorescent lamp. The study found that the increasing of waste ratio in solidification process has the trend to increase density and mercury leaching concentration. Different binder ratios and waste ratios produced different strength effects on the solidified sample. Mercury leaching concentration decreased with increasing curing times, whereas the density and the strength trend to decrease after 14 days. In consideration the properties of solidified sample and cost of solidifying material, a ratio of cement to lime to fly ash of 0:30:70 was found to be the most optimum ratio for solidifying spent fluorescent lamps (at a ratio of spent fluorescent lamp to binder of 2:1), with curing time more than 7-days. Accordingly, it is reasonable to assume lime and lignite fly ash are considerably better for use as a cement replacement alternative for spent fluorescent lamp solidification.Publication Open Access Assessing governability of environmental protected areas in Phetchaburi and Prachuap Kirikhan, Thailand(2015) Suvaluck Satumanatpan; Ratana Chuenpagdee; Mahidol University. Faculty of Environment and Resource StudiesEnvironmental degradation continues in Thailand, despite the establishment of several environmental protected areas (EPAs) since their inception in 1992. EPAs aim to promote the conservation and sustainability of natural resources through decentralization and improving the participation of local governments and communities. Not all EPAs are successful, however. The purpose of this paper is to examine factors affecting the implementation of the EPAs program in Thailand, using the Phetchaburi and Prachuap Kirikhan EPA, in southern Thailand as a case study. Following the governability assessment framework, natural, social, and governing systems associated with the EPA were first described in terms of diversity, complexity, dynamics, and spatial and jurisdictional scale. Next, we examined the extent to which the EPA, as a participatory regulatory tool, corresponded with the natural and social systems it aimed to govern. The analysis reveals that the EPA did not function as effectively as it should be, even though the governing system was well structured to deal with complex coastal ecosystems in the area. The deficiency in the function of the EPA was due largely to poor sectoral coordination, weak financial commitments, and uncoordinated governing interactions. Based on these findings, we suggest that the EPA should be situated in a broader context of land and marine spatial planning and that it needs to be attuned to existing policies in a way that collaboration between agencies and policy integration is possible.Publication Open Access Comparison of the physical and chemical properties of Briquette and Wood Charcoal in Khammouane Province, Lao PDR(2009-06) Vongsaysana Sayakoummane; Achara Ussawarujikulchai; Mahidol University.
