Publication Metadata only Assessment of Water Resources Pollution Carrying Capacity in the Sa Kaeo Special Economic Zone, Thailand(2021-09-01) Chitsanuphong Pratum; Faculty of Environment and Resource Studies, Mahidol Universityand assess the pollution carrying capacity of the natural water resource. The sampling sites were examined 7 stations cut across the downstream areas. All these stations were served as the control station to represent the actual condition of the Phromhot... quality standard of the Ministry of Natural Resources and Environment, Thailand. In addition, it can flow into the water body up to 6,439.55 m3/day. The maximum amount of a pollutant (in terms of BOD loading) allowed to enter a water body of the PhromhotPublication Metadata only A mathematical model for pollution in a river and its remediation by aeration(2009-03-01) Busayamas Pimpunchat; Winston L. Sweatman; Graeme C. Wake; Wannapong Triampo; Aroon Parshotam; Mahidol University; King Mongkut's Institute of Technology Ladkrabang; Massey University, Auckland; National Institute of Water and Atmospheric Research, New Zealandanalytically. We also present a numerical approach to the solution in the general case. The extension to the transient spatial model is relatively straightforward. The study is motivated by the crucial problem of water pollution in many countries...We present a simple mathematical model for river pollution and investigate the effect of aeration on the degradation of pollutant. The model consists of a pair of coupled reaction-diffusion-advection equations for the pollutant and dissolved oxygenPublication Metadata only Human Fecal Pollution Monitoring and Microbial Risk Assessment for Water Reuse Potential in a Coastal Industrial–Residential Mixed-Use Watershed(2021-04-20) Akechai Kongprajug; Thammanitchpol Denpetkul; Natcha Chyerochana; Skorn Mongkolsuk; Kwanrawee Sirikanchana; Chulabhorn Research Institute; Faculty of Tropical Medicine, Mahidol University; Thailand Ministry of EducationRapid economic development has caused industrial expansion into residential communities, leading to higher fecal pollution loads that could be discharged into aquatic environments. However, little is known regarding the potential microbial impact... samples from all three events, indicating continuing fecal pollution in the area, mostly from human sewage contamination. This was shown by the human-specific genetic marker crAssphage (88.9%) and human polyomavirus (HPyVs; 92.6%) detection. Enteric humanPublication 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 Universityand urban construction land act as a source of the water quality pollution load, while forest land intercepts and absorbs pollutants. Therefore, the water environmental protection in the Mun River basin should be based on non-point source pollution control...© 2020 Editorial Board of Journal of Agro-Environment Science.

Analyzing the relationship between land use and water quality at different spatial scales is of great value for understanding the causes and trends of waterPublication Metadata only The 2nd International Symposium on Water Pollution and Treatment (ISWPT 2019)(2020-01-16) Nuanchan Singkran; Faculty of Environment and Resource Studies, Mahidol UniversityPublication Metadata only Performance of viral and bacterial genetic markers for sewage pollution tracking in tropical Thailand(2021-02-15) Watsawan Sangkaew; Akechai Kongprajug; Natcha Chyerochana; Warish Ahmed; Surapong Rattanakul; Thammanitchpol Denpetkul; Skorn Mongkolsuk; Kwanrawee Sirikanchana; Chulabhorn Research Institute; CSIRO Land and Water; Mahidol University; King Mongkut's University of Technology Thonburi; Ministry of Higher Education, Science, Research and Innovationand specific for tracking sewage pollution in aquatic environments of Thailand. This study underlines the importance of characterizing and validating MST markers in host groups and environmental waters before including them in a water quality management toolbox....Identifying sewage contamination via microbial source tracking (MST) marker genes has proven useful for effective water quality management worldwide; however, performance evaluations for these marker genes in tropical areas are limited. ThereforePublication 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 Modelling river pollution and removal by aeration(2007-12-01) B. Pimpunchat; W. L. Sweatman; W. Triampo; G. C. Wake; A.
