Item Metadata only Water Use Quality Situation over 10 Years (2010 to 2019) of Hospitals under the Ministry of Public Health, Thailand(2022-05-01) Peeratoranit T.; Sreesai S.; Sillabutra J.; Mahidol Universityindicators; total coliform bacteria (43.9%) and fecal coliform bacteria (33.2%). Water parameters related to exceeded total and fecal coliform bacteria standards included turbidity, nitrate, chloride and pH levels. The highest explicit turbidity relationship... of occurrence probability exceeded the quality standards with total and fecal coliform bacteria 3.7 and 4.3 fold, respectively. Onsite hospital water treatment is needed to ensure safe conditions. The significant chemical parameters can be used as a rapid toolPublication Metadata only Assessment of a potential agricultural application of Bangkok-digested sewage sludge and finished compost products(2013-09-01) Siranee Sreesai; Panadda Peapueng; Taninporn Tippayamongkonkun; Suthipong Sthiannopkao; Mahidol University; Center of Excellence on Environmental Health and Toxicology; National Cheng Kung UniversityA study was conducted to investigate the levels of plant nutrients, heavy metals, parasites and fecal coliform bacteria in Bangkok-produced sewage sludge and finished compost products for potential agricultural application, as well as to compare... (1.16 ± 0.22%), but it was contaminated with human pathogens, including fecal coliform bacteria, viable helminthes egg and active forms of parasite cysts. Thus, fresh sewage sludge should not be disposed on land unless it has undergone pathogenPublication Metadata only A predictive model of the impact of urbanization on bacterial loads in watersheds(2021-05-15) Chantima Piyapong; Nitcha Chamroensaksri; Sayam Aroonsrimorakot; Lawan Eyosawat; Surasak Khankhum; Sunirat Rattana; Nuchsupha Sunthamala; Panya Warapetcharayut; Emmanuel Paradis; Mahidol University; Burapha University; CNRS Centre National de la Recherche Scientifique; Thailand National Science and Technology Development Agency; Mahasarakham University; Ministry of Natural Resources and Environment; Ministry of Natural Resources and Environment; Ministry of Natural Resources and Environmentin eight watersheds in Eastern Thailand to quantify the temporal and geographical variation in total and fecal coliform bacteria. Descriptive statistics showed considerable seasonal, inter-annual, and geographical variation. In order to quantify this multi... on the bacterial concentrations. Urbanization was an important factor controlling concentrations of bacteria in rivers: we found that the proportion of urban area around a station had a statistically significant effect on log-transformed total coliform bacterialPublication Metadata only Suitable types and constituent ratios for clay-pot water filters to improve the physical and bacteriological quality of drinking water(2014-01-01) Watcharaporn Wongsakoonkan; Tawach Prechthai; Kraichat Tantrakarnapa; Mahidol Universityand ratios for clay-pot water filters. The clay-pots were prepared by combining clay with sand, coconut-shell charcoal, and rice-husk charcoal, at various ratios. The results indicated that all types and ratios could remove 100% of coliform bacteria... significantly different filtration rates (p>0.01). A ratio with a maximal filtration rate of 60:40(0.38 ± 0.28 mL/cm2/hr) was found to be suitable. The quality of filtered water was acceptable in terms of turbidity, coliform bacteria level, and Escherichia coliPublication Metadata only Association of sanitary conditions and bacteriological quality of tube ice in ice plants in metropolitan Bangkok, Thailand(2010-01-01) Kraichat Tantrakarnapa; Prasert Makkaew; Pisit Vatanasomboon; Tharadol Kengganpanich; Mahidol Universitypassed sanitary condition criteria. 23% of Tube Ice samples were acceptable in the standard permission level in terms of Total coliform bacteria and Fecal coliform bacteria. All Tube Ice plant processing water samples were acceptable in comparisonPublication Metadata only Problem identification on surface water quality in the Mun River Basin, Thailand(2020-08-01) Arika Bridhikitti; Thayukorn Prabamroong; Guo An Yu; Institute of Geographical Sciences and Natural Resources Research Chinese Academy of Sciences; Mahidol University; Mahasarakham Universitydependent. During the monsoon, water quality was often found with high coliform bacteria. Salinity problem was substantial, particularly during the early monsoon in the upper northern part. The dry-season water quality was even worse, exhibiting high... loadings of organic compounds, coliform bacteria, nutrient, and low dissolved oxygen. This poor water quality was found in Lam Takhong Sub-Basin and the lower basins—including the lower part of the main river, Huai Samran Sub-Basin, and Lam Se Bai Sub-BasinItem Metadata only Quality of sources of drinking water and health among the hill tribe people of northern Thailand(2022-03-01) Sudsandee S.; Fakkaew K.; Siriratruengsuk W.; Worakhunpiset S.; Apidechkul T.; Mahidol Universityfor biological, chemical and physical qualities, which were compared with the standard parameter values for safe drinking water according to the World Health Organization. Total coliform bacteria and fecal coliform bacteria, which represented the biologicalPublication Metadata only Integrated analyses of fecal indicator bacteria, microbial source tracking markers, and pathogens for Southeast Asian beach water quality assessment(2021-09-15) Akechai Kongprajug; Natcha Chyerochana; Surapong Rattanakul; Thammanitchpol Denpetkul; Watsawan Sangkaew; Pornjira Somnark; Yupin Patarapongsant; Kanokpon Tomyim; Montakarn Sresung; Skorn Mongkolsuk; Kwanrawee Sirikanchana; Chulabhorn Research Institute; Faculty of Tropical Medicine, Mahidol University; Sasin School of Management, Bangkok; Chulabhorn Royal Academy; Thailand Ministry of Education; King Mongkut's University of Technology ThonburiThe degradation of coastal water quality from fecal pollution poses a health risk to visitors at recreational beaches. Fecal indicator bacteria (FIB) are a proxy for fecal pollution; however the accuracy of their representation of fecal pollution... and pathogenic bacteria, and physicochemical parameters and rainfall. Forty-two marine water samples were collected from seven sampling stations during six events at two tourist beaches in Thailand. Both beaches were contaminated with fecal pollution as evidentPublication Metadata only Relationship between water quality and land use at different spatial scales: A case study of the Mun River basin, Thailand(2020-01-01) Hao Yu Tian; Ling Tong; Guo An Yu; Bridhikitti Arika; Institute of Geographical Sciences and Natural Resources Research Chinese Academy of Sciences; China Agricultural University; Mahidol Universitynitrogen, ammonia nitrogen and suspended solids were 0.86, 0.38, 0.35, 0.40, 0.45, and 0.50, respectively, thereby showing significant spatial aggregation in the basin.
