Publication Open Access The usage of gibberellin-rich seed-waste for vegetable growth enhancement: A case study of rambutan seed(2014) Kanokwan Karawake; Winai Nutmagul; Charlie Navanugraha; Saranva Suncharitgul; Monthira Yuttithum; Rungjarat Hutacharoen; Rungjarat Hutacharoen; Mahidol University. Faculty of Environment and Natural Resource StudiesThis research aims to study the feasibility of plant growth enhancement by Extracted Gibberellic Compounds (EGCs) of rambutan seed-waste, with 3 extracted solvents: 80% methanol, 80% ethanol and rice whisky, and at the considered ratios (wt./vol.) of rambutan seeds (grams) and extracted solvent (milliliters) of 1:1, 1:2 and 1:3. The growth enhancement was identified through the Lettuce Hypocotyl Bioassays (LHB) method. Among the 5 species of lettuce (Grand rapids, Red cos, Red oak, Red coral, and green oak) for bioassays, the Green Oak lettuce was finally determined to be the representative lettuce for LHB. The 2.1 % of diluted EGC (methanol solvent, ratio 1:1) performed better as a growth enhancer than the other EGAs. Moreover, the same EGC type revealed a non-significant difference of growth enhancement with standard GA3 at 0.1 ppm. (p > 0.05). Therefore, the 2.1% EGC (methanol, 1:1) had gibberellic acid equivalent (GAE) to 0.1 ppm standard GA3. In application to Water Morning Glory growth enhancement, the introduction of EGC (Methanol,1:1) with the dilution ratio 1:1 with water performed significantly different (p<0.05) in height and no-significant difference ( p>0.05) in fresh weight with the control (water).Publication Open Access Soil physicochemical status and nutrient management for paddy soils in the lower central plain of Thailand after the flood disaster in 2011(2014-06) Benjaporn Intorpetch; Worachart Wisawapipat; Chumlong Arunlertaree; Piyakarn Teartisup; Mahidol University. Faculty of Environment and Natural Resource StudiesThe soil fertility status were evaluated for 29 paddy soils in Phra Nakhon, Si Ayutthaya and Pathum Thani provinces, Thailand that had been affected by the flood disaster in 2011. The chemical fertility status of the soils in the flood affected areas was medium, which is relatively superior to the pre-flood condition. The available potassium in most soils was slightly larger (mean = 220 mg kg-1) than the values previously reported on these soils (mean = 188 mg kg-1). However, mean values of available phosphorus for most soils were rather small (7.5 mg kg-1), indicating a loss of phosphorus fertility and those farmers in the flood affected areas needed to apply additional phosphorus fertilizer in order to achieve satisfactory crop yields. Liming should also be used to minimize potential Al/metals toxicity and correct imbalances of plant nutrients. Several plant nutrients (NPK) and organic materials need to be regularly applied to maintain soil fertility levels at optimum values.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 Engineering. Department of Civil and Environmental EngineeringIn order to establish green logistic systems, life cycle assessment (LCA) is an important tool for evaluating and comparing overall environmental impacts from various options. Most LCA studies rely on readily available secondary databases on transport services such as Ecoinvent database and scientific publications. The most widely applied Ecoinvent database on transport services is aggregated with specific transport variables and statistics based on European and Swiss average data. To modify the life cycle inventory (LCI) database with specific variables (e.g. load factors, driving speed, etc.) is very complicated and may not be possible. Such studies are still lacking due to complexity and resource limitations. This study aims to provide a framework for LCI modelling to conduct LCAs of European freight transport with up-to-date LCI data in terms of emissions and transport variables. The framework comprises of a conceptual transport model, important transport variables and data sources for freight transport by road and by rail in Europe. The data collection was carried out by literature studies and interviews with relevant experts. The framework is useful for LCA practitioners, researchers and industries to include specific transport variables and to adequately assess the environmental impacts from transport activities by road and by rail.Publication Open Access Waste water minimization: Utilization of rubber latex residue and swine dung as fertilizer for Para rubber seedling growth(2012-06) Thanya Uttraporn; Saranya Sucharitaku; Gritsanaruck Theeraraj; Chumporn Yuwaree; Charlie Navanugraha; Rungjarat Hutacharoen; Rungjarat Hutacharoen; Mahidol University. Faculty of Environment and Natural Resource StudiesCentrifuged residue of concentrated latex production is the by-product or waste of latex processing of the Hevea tree (Heveabrasiliensis). The 10-15% residue of fresh latex causes waste disposal cost and environmental problems for factories. Because this residue contains some nutrients (N, P, K) in available forms, it can potentially enhance para-rubber tree growth. However, this centrifuged residue (CR) has some small rubber pieces mixed within that needs to be blended to prevent soil problems. The waste of swine dung or manure (SD) has similar problems on farms. This waste contains some essential plant nutrients, but it requires a period of time for microorganisms to decompose into the available compounds for plant growth. Thus, the blended fertilizer of latex residue with swine dung can potentially act as a preferable blended fertilizer because the nutrients from both wastes can enhance the plant growth from the initial stage. The aim of this study was to study the feasibility and effectiveness of the blended fertilizer at consideration ratio of 1:1 (CR and SD) alone and at nutrient adjustment to equal to chemical fertilizer usage for Hevea tree as a study case. We found that the blended fertilizer was feasible for para rubber seedlings, from the view point of growth enhancement, soil properties and water leachates.Publication Open Access Blood cockle shell: an agro-waste for N and P removal of shrimp farm effluent(2013-06) Mothinee Aopreeya; Chumlong Arunlertaree; Chumporn Yuwaree; Rattana Boonprasert; Rungjarat Hutacharoen; Rungjarat Hutacharoen; Mahidol University. Faculty of Environment and Natural Resource StudiesThis research investigated the removal efficiency of burned (activated) blood cockle shells (BBCS) of the total nitrogen (N) and phosphorus (P) effluent from shrimp farms, in comparison with novel activated charcoal (AC) and natural (unactivated) blood cockle shell (grinding, NBCS). All shell types (BBCS, NBCS) performed well as adsorbents The removal efficiency varied with shell particle size and effluent flow rate. The shell particle size of BBCS at 0.85-2.0 millimeters had the highest removal efficiency of total N and P at 86.66% and 87.63%, respectively. The best flow rate of effluent for N and P removal efficiency through adsorbency were 300 ml/hour. Moreover, the equilibrium model study for adsorption isotherm of BBCS performed better fitted to the Langmuir model in nitrogen removal, and to both Langmuir & Freundlich model in phosphorus removal. Our findings indicated that the higher surface area and larger average pore size of the adsorbents as BBCS (Bunauer, Emmett and Teller method: BET) produced more N and P removal efficiency than the lower one as NBCS.Publication Open Access Forest habitat and fruit availability of hornbills in Salakphra Wildlife Sanctuary, Kanchanaburi Province, Thailand(2015) Hata, Hiroki; Vijak Chimchome; Jongdee To-im; Jongdee To-im; Mahidol University. Faculty of Environment and Natural Resource StudiesThis study aimed to examine the quality of hornbill habitat in terms of tree and fruit availability in mixed deciduous forests, Kanchanaburi Province, Thailand. Salakphra Wildlife Sanctuary (SLP) has been known as a mixed deciduous forest, which has been disturbed by human activities. All canopy trees with a breast height diameter (DBH) ≥ 10 cm within the ten belt-transects of 2,000 m X 20 m (a total of 40 hectares) were monitored monthly. A total of 30 tree families including 81 species were observed on the belt-transects and the dominant species were non-hornbill fruit species. As hornbills needs emergent tree for nesting, trees with DBH size ≥ 40 cm were regarded as a potential nest tree and 37.78 % of trees were found in SLP. The abundance of preferred nest tree species (families Dipterocarpaceae, Myrtaceae and Datiscaceae) were 12.14%. The density of Ficus spp., which is regarded as the most important food source for hornbill, is 0.55 trees / ha in SLP. The Fruit Availability Index (FAI) of all fruit species during the breeding season is 23.49 % while the FAI of hornbill fruit species is 58.88 %. Furthermore, in addition to this study, a pair of Great hornbills was observed during the breeding season and the male abandoned the nest to feed the mate prior to the expected hatching period. A pair of great hornbills was observed during the breeding season in SLP and the male would only leave the nest to find and retrieve food for the female mate prior to the expected hatching period. The average estimated number of food items fed to the female mate was 220 food items during the period from March (n = 3) to 13 food items in April 2014 (n = 4). The reduction in the availability of food items may be considered as one of the factors that affect the success or failure of producing offspring.Publication Open Access Tobacco smoke pollution from designated smoking rooms in Bangkok’s Major International Airport(2015) Jintana Peesing; Naowarut Charoenca; Aungsiri Tipayarom; Nipapun Kungskulniti; Hamann, Stephen L.; Siriwan Pitayarangsarit; Mahidol University. Faculty of Public HealthLevels of fine particulate matter with diameters of less than 2.5 microns (PM2.5), an indicator of secondhand smoke, were measured at Bangkok‟s International Airport in: 1) Designated smoking room(s) (DSR) (2) just outside these smoking rooms ,and (3) in other areas where smoking is prohibited in the main airport building. TSI SidePak AM 510 monitoring equipment was employed to monitor PM2.5 for 30 minutes/sample. PM2.5 samples were taken inside six selected DSR, just outside the same DSR and at other smoke–free areas inside the building, which included airline lounges, in the walkway to boarding gates, at arrival waiting areas, and at check–in service areas. The level of PM2.5 averaged 151.9 μg/m3 in smoking rooms, 12.0 μg/m3 just outside DSR, and 9.0 μg/m3 in areas where smoking is not allowed. PM2.5 values inside smoking rooms were fifteen times the WHO annual air quality standard of 10 μg/m3, whereas the levels outside the DSR were also elevated above the WHO standard. These findings indicate health risks in smoking rooms for travelers visiting the airport with leakage to areas just outside the DSR. Results suggest that smoking rooms at the international airport should be removed.Publication Open Access Tourism threats to Coral Reef Resilience at Koh Sak, Pattaya Bay(2015-01) Phillips, Wayne N.; Mahidol University. Mahidol University International CollegeCoral reefs provide many ecosystem goods and services and rising atmospheric greenhouse gas concentrations are resulting in higher than normal sea surface temperatures (SSTs), increasing the frequency and extent of mass coral bleaching and mortality. The loss of corals after bleaching events is often followed by changes in the reef community and the proliferation of macroalgae, especially in reefs experiencing tourism and fishing. This change, however, is less likely in reefs experiencing fewer negative impacts. Using a mixed methods approach to data collection we used boat-traffic surveys, coral reef substrate surveys and self-complete questionnaires and interviews of scuba divers, island visitors and their tour guides to assess potential tourism impacts to the coral reef at Koh Sak, Pattaya. The number of tourists, the intensity of boat traffic and poor management of activities at the island impair the structural and ecological integrity of the reef thereby affecting its ecological and spatial resilience and capacity to survive global climate change. To improve reef resilience, there needs to be a shift from exploitative business practices to a conservation-based industry that creates the infrastructure to ensure visitors participate in activities that help conserve the reef rather than weaken it.Publication Open Access Effects of climate variability on monthly growth of Aglaia Odoratissima and Hydnocarpus Ilicifolia at the Sakaerat Environmental Research Station (SERS), Northeastern Thailand(2015) Kritsadapan Palakit; Khwanchai Duangsathaporn; Somkid Siripatanadilok; Pichit Lumyai; Kritsadapan Palakit; Mahidol University. Faculty of Environment and Natural Resource StudiesThe research objective was to investigate effects of climate variability on monthly growth of Aglaia odoratissima and Hydnocarpus ilicifolia which are the dominant tree species in lower canopies of dry evergreen forest and generally found at the Sakaerat Environmental Research Station (SERS), northeastern Thailand. For one year of the investigation, monthly data of tree leaf phenology, inside bark diameter (IBD) and outside bark diameter (OBD) increments were examined. These data were related to soil moisture content and climatic data of monthly rainfall, temperature and relative humidity. The results showed that leaf phenology of A. odoratissima and H. ilicifolia illustrated leaf maturation throughout the year, while young leaves were abundant in the rainy season and leaf abscission was rarely found throughout the year. The IBD increments of these species on transverse surfaces could be detected throughout the year and the most rapid increments were detected in the rainy season, while OBD increments of both species shrank in the dry season and swelled in the rainy season. Using path analysis (PA), climate variability was found to be significantly related to leaf phenology of A. odoratissima and IBD increments of H. ilicifolia; and it was also significantly related to OBD increments of both species.
