Greenhouse gas (GHG) mitigation is one of the major challenges that all countries face. The impacts of GHG emissions cost people and ecosystem everywhere. Hence, it is the responsibility of all parties to tackle this serious problem. For instance, Thailand has agreed to decrease GHG emissions by 20 % from the projected business-as-usual (BAU) level by 2030 despite no commitment to target GHG emissions reduction. As a part of the contribution, this study aimed at preparing a GHG emissions inventory (EI) from the main pollution sources in Phayao province located in the North of Thailand. We investigated annual amount of GHG emissions by using a bottom-up approach. Both primary data from field survey and secondary data from governmental agencies in Thailand were employed in our analysis. From the preliminary study, Phayao’s economy depends on agriculture, like other ASEAN countries. The major sources of GHG generation comprised of rice cultivation, open burning (including crop residue burning and forest fire), road transportation, industry, and livestock (from enteric fermentation and manure management). GHG emissions from rice fields, open burning, road transportation, industry, and livestock were estimated to be 773,325; 1,819,225; 195,497; 4,625 and 133,830 t CO2-eq. Approximately 89 % of GHG emissions were emitted from agricultural sector (biomass open burning and rice cultivation). The results of this study suggest that the proper and effective measures for mitigating GHG emissions from agricultural ecosystems is the first priority to emphasise.

With an increased awareness of sustainability issues, natural ventilation has become an elegant method for reducing the costs and environmental effects of the energy that is used to maintain comfortable indoor air quality rather than using mechanical ventilation. The windows in many industrial buildings are continuously open to exhaust pollutants and intake fresh air. Though windows are functional and efficient for natural ventilation, rainwater is able to penetrate through the windows during wind-driven rain. For industries in which the moisture content affects the quality of the product, the intrusion of a large amount of rainwater through windows must be prevented without compromising the effective ventilation. The aim of this research is to determine an innovative design for windows to accomplish the optimum of high ventilation and low rain penetration. For this purpose, windows are variously innovated and tested in full-scale measurements, reduced-scale wind-tunnel measurements and computational fluid dynamics (CFD). An artificial rain and wind velocity to mimic the average of the maximum values in Korea are created. The maximum reduction in rain penetration of over 98% compared to basic 90° open windows is attained with only a 4%–9% decrement of ventilation efficiency in the two recommended designs.

Investigation of an odor source in Changwon City using multi-monitoring methods. A case study of Korea

Environment Protection Engineering · 2015

It is a regular occurrence for residents living near industrial plants to complain regarding odor problems. Those plants may also try to protect themselves from liability by demonstrating some environmental evidence. An investigation to prove whether the accused industrial complex is the major source of released odors among several potential sources of odor problems was carried out using the combination of measurement techniques. The multi-monitoring methods comprise utilizations of olfactory system, questionnaire, electronic detector and chemical analysis. This study demonstrated the achievement of integrating scientific monitoring methods to support the enforcement of odor acts for management in the industrial city.

Foot-and-mouth disease virus (FMDV) is one of the most economically serious veterinary pathogens due to its negative effects on livestock’s condition and its highly infectious nature via variety of exposure paths through the oral and inhalation routes. Measures to enhance outbreak management can be designed according to analytical results predicted by mathematical models for wind-borne dispersion, an important path of virus transmission. Accurate atmospheric dispersion models are useful tools for properly determining risk management plan while inaccurate models may conversely lead to accidental loss in 2 possible ways. Over strict measure, for example, slaughter for too wide area can cause severe economic difficulties such as irreversible loss of ability to operate business for a number of farms. On the contrary, inestimable loss possibly caused by lax control is a persistent epidemic. In this paper, available modelling procedures with different advantages and limitations for forecasting the spread of FMDV that have been undertaken since the 1970s are reviewed for the purpose that it can be suitably applied with various conditions in any further emergency cases

Foot-and-mouth disease virus (FMDV) is one of the most economically serious veterinary pathogens due to its negative effects on livestock and its highly infectious nature via a variety of transmission paths through oral and inhalation routes. Measures to enhance outbreak management can be designed according to analytical results predicted by mathematical models for wind-borne dispersion, an important path of virus transmission. Accurate atmospheric dispersion models are useful tools for properly determining risk management plans, while inaccurate models may conversely lead to accidental loss in two possible ways. Overly strict measures, e.g., slaughter for too wide an area, can cause severe economic difficulties, including irreversible loss of business operations for a number of farms. On the contrary, inestimable loss potentially caused by lax controls is a persistent threat. In this paper, available modelling procedures for forecasting the spread of FMDV, which have been used since the 1970s, each having its advantages and limitations, are reviewed for the purpose of ensuring suitable application in various conditions of any future emergency cases.
