Item Open Access River cleaner : a game for teaching aquatic ecosystem conservation via garbage management(Mahidol University. Mahidol University Library and Knowledge Center, 2022) Pachara Lersintavanon; Mores Prachyabrued; Worapan KusakunniranNews about pollution and solid waste destructively entangling the cities and water environment, e.g., rivers, has strikingly been coming to light from time to time. As it is irrefutable that humans’ behaviors are essentially root causes... of the pollution related problems owing to carelessness and insufficient level of care and attention towards the environment, an attempt to fix such problems is obligatory and must be initiated, principally by promoting self-discipline and highlightingPublication Open Access Emission clinic green service: Environmental management for car and motorcycle maintenance center(2010-12) Sayam Aroonsrimorakot; Mahidol University.

This research is under the integrated research project on community... development for sufficient health under the “Sufficient Economy Philosophy”. Results from community meetings suggest that water pollution is a major community concern related to their way of life and community health. As a result, surveys of the canalPublication Open Access Simultaneous Detection of Feces - specific Bacteriophages of Bacteroides fragilis with a Duplex PCR Assay(2018) Natcha Chyerochana; Benjarath Pupacdi Javed; Pornjira Somnark; Skorn Mongkolsuk; Kwanrawee Sirikanchana; Chulabhorn Research Institute.

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.
