Exposure to PM2.5 has been known to cause a variety of serious health consequences. Quantifying and investigating the health effects of PM2.5 pollution are imperative to understand and collect scientific evidence for supporting policies and associated actions. In this paper, we reviewed published environ-mental epidemiological studies and health risk assessments evaluating the health impacts of PM2.5 exposure in the PubMed database to identify the attributes of each method and aggregate the health impact results to perform analyses and summaries. Forty-two studies were identified after applying our search strategy, inclusion, and exclusion criteria. The epidemiological studies found an increased risk of several diseases from short- and long-term exposure, such as cardiovascular and respiratory diseases, lung cancer, stroke, pneumonia, depression, and diabetes. However, several conditions remain to be explored as the associations remain unclear, such as asthma, bronchitis, breast cancer, Parkinson’s disease for long-term exposure, chronic obstructive pulmonary disease, stillbirth, and hypertension for short-term exposure. Health risk assessment (HRA) studies at a global scale found more than 4 million deaths from diseases associated with PM2.5 exposure. These studies also emphasized the importance and benefits of health guidelines that demonstrated to help avoid the number of fatalities significantly, especially guidelines from the World Health Organization (WHO) that showed the highest benefit. HRA studies in Thailand also showed that the country's air quality needs to be improved to avoid deaths and hospital admission cases. We also found that cohort studies for the Thai population are required to improve the quality of data and limit overestimation from using global estimates. Finally, the benefits and limitations of each study approach were collated to assist future studies in determining the most suited instruments for their purposes.

Environment Development and Sustainability · 2023

Abstract Clean water and sanitation are essential for human development. Governments, international and national aid organizations have implemented water, sanitation, and hygiene (WASH) projects worldwide, notably in low- and middle-income countries. However, the majority of such projects experience failure. As a result, 2.4 billion people worldwide are deprived of improved WASH services. Research revealing how WASH projects can be sustained and which factors need to be considered is crucial. Despite the gap and its importance, existing studies on the sustainability assessment of WASH projects are limited. This study attempted to assess and compare the sustainability of WASH projects in Myanmar that used the Community Led Total Sanitation (CLTS) and Participatory Hygiene and Sanitation Transformation (PHAST) approaches with the “Sustainability Check” developed by The United Nations Children’s Fund (UNICEF). This research also evaluated the extent to which WASH projects contributed to the Myanmar National WASH Strategy. The study results show that both CLTS and PHAST project operations fully met the sustainability standards regarding accessibility and intra-village equity. Other sustainability indicators, such as water quality, use of sanitation facilities, and handwashing facilities, were at or above 85% and had already met the 2025 national targets. In contrast, handwashing practices have reached the 2030 national targets. The findings revealed that technical factors, institutional factors (at the community level), social, financial, and sanitation factors contributed to WASH project sustainability. The results also highlight the need for strengthening collaboration with local government to ensure that communities receive post-implementation support from local authorities, to encourage community participation and foster sense of ownership, to empower community-based bodies for O&M and monitoring of water and sanitation facilities, to integrate appropriate behavioral change activities, and to align with the National WASH Strategy. This study would be beneficial for WASH practitioners to ensure the inclusion of factors that support sustainability in the execution of future WASH projects. Graphical abstract

Sustainability · 2022

The majority of municipal solid waste in Thailand is organic waste including food and garden waste. Improper waste management has caused negative impacts on the environment. This study aimed to find a hypothetical municipal organic waste management scenario with the lowest environmental impacts using life cycle assessment (LCA). The system boundary of organic waste management includes collection and transportation; treatment, including centralized and on-site treatment technologies; and by-product utilization. The two main waste management systems considered in this study were centralized and on-site waste management systems. The first two scenarios take into account all the amount of the municipal organic waste collected and transported and then treated by centralized waste treatment technologies (composting, anaerobic digestion, and landfill). The remaining three scenarios are integrated between 10% on-site (home composting, food waste processor, and composting bin) and 90% centralized (composting, anaerobic digestion, and incineration) waste treatment technologies; the scenario combining centralized (food waste anaerobic digestion, garden waste composting, and incineration) and on-site (home composting) systems yielded the lowest environmental impacts (except short-term climate change, freshwater, and marine eutrophication). On-site systems can help reduce collection, transportation, and treatment impacts, particularly photochemical oxidant formation, which was proportional to the amount of waste or distance reduced. Benefits from the by-product utilization can offset all impacts in terms of fossil and nuclear energy use and freshwater acidification, and result in a negative impact score or impact reduction. This research can be used as guidance for developing countries with conditions and waste composition similar to Thailand for making initial decisions on environmentally sustainable municipal organic waste management.

Abstract Purpose Existing emission and toxicity characterization models in life cycle assessment are currently not suitable for assessing pesticide-related impacts of crop cultivation in tropical regions. This study aims to parameterize the scientific consensus model USEtox for Thai environments to derive toxicity characterization factors of pesticide emissions from agricultural systems in Thailand. Potential human toxicity and ecotoxicity impacts and related damage costs of pesticides used on nine crops cultivated in Thailand are quantified. Methods Considering country-specific conditions, USEtox was adapted by applying the landscape and consumption parameters specific to Thailand. Related Thai-specific characterization factors of identified pesticides used in Thai agriculture were quantified. Four emission inventory models were applied to determine pesticide emission fractions in different environmental compartments. The consistent combination of pesticide emission mass and associated characterization factors yielded potential toxicity impact scores. Pesticide impact-related damage costs (external costs) on human health and ecosystem quality were quantified using valuation factors for Thailand. The crops with the highest total damage costs were selected and compared with the annual net incomes of the respective crop production systems. Results and discussion Pesticide toxicity impacts assessed by using Thai-specific factors were different from the use of global average factors ranging from 1 to 169% (human toxicity) and from 0.1 to 3587% (ecotoxicity). Our results indicated the variability in impact scores influenced by emission modeling choices. Following PestLCI consensus emission estimation model, mango cultivation showed the highest human toxicity impacts of 0.07 DALY/ha, resulting in high human health damage costs mainly caused by Propineb (93%). Rice cultivation with a dry direct-seeded system exhibited the highest ecotoxicity impacts (3934 PDF m 3 day/ha) and associated damage costs mainly caused by Oxadiazon (92%). Pesticides used in cultivation of nine crops resulted in total damage costs of 7188 and 3.01 million THB/crop-year for human health and ecotoxicity, respectively. Mango and rice production accounted for 70% and 17% of the total damage costs, which were 36% and 20% of the respective crops’ annual net income. Conclusions Our study illustrates the ranking of pesticides applied throughout the crop calendar causing toxicological impact and related damage costs on human health and ecosystem quality. This helps identify crops and the main contributors to pesticide-related toxicity impacts in Thailand. Our study highlights the need for proper emission quantification and for the use of characterization factors locally parameterized to increase accuracy. Our results will be useful for future improvement toward more sustainable pesticide use. Graphical abstract

One of the main challenges in developing countries like Nepal is inefficient management of municipal solid waste. Provision of fundamental services for municipal solid waste management is a major concern in urban areas of Nepal, especially in the capital Kathmandu Metropolitan City (KMC). The formal waste management system of KMC is limited to collection and disposal in landfill site or open dumping. Intermediate steps are not opted formally for resource recovery or treatment of the waste. In view of the challenges encountered, the Asian Development Bank has recommended adopting integrated solid waste management. The study aims at developing and accessing scenarios for integrated solid waste management that is pertinent to the case of KMC. The specific objectives include defining different integrated solid waste management systems and determining their energy recovery and material recovery efficiencies. The first waste management system is material recovery-based system. The second waste management system is energy and material recovery-based system. Additionally, a SWOT (strengths, weaknesses, opportunities, and threats) analysis of the two proposed waste management systems was carried out to recommend the more appropriate system, in the context of KMC. Results of the study depicted that material recovery efficiency of the second system is lower than the first system, however, the electrical energy efficiency is especially prominent for second system. Based on the results of material and energy recovery efficiency calculations and the outcomes of the SWOT analysis, adoption of the material and energy recovery based waste management system is found to be instrumental for efficient management of municipal solid waste in the context of KMC. In view of the negative impacts imposed by the current improper municipal solid waste management in KMC, implementation of the material and energy recovery based integrated solid waste management system will be beneficial in not only effectively managing the municipal solid waste but also provide resources by recovering material and energy from the waste generated. However, if following the waste hierarchy, the material recovery based system would be preferable. In the short term, the energy and material recovery-based system may be considered. But risks of technological lock-in effects in the long term can be detrimental in realizing and taking advantage of the material recovery potentials.

Environmental Sustainability of Food Consumption in Asia

Biraj Adhikari, Trakarn Prapaspongsa

Sustainability · 2019

This study assesses the environmental sustainability of food consumption in Thailand, India, China, Japan, and Saudi Arabia by using a life cycle assessment. These five Asian countries were selected according to the differences in surface area, population density, GDP, and food consumption patterns. The data were obtained from Food and Agriculture Organization food balance sheets, Ecoinvent 3.4 and Agri-footprint 4.0 databases, and scientific publications. The environmental impact categories chosen were global warming, terrestrial acidification, eutrophication, eco-toxicity, human toxicity, and fossil resource scarcity. The impact assessment was carried out by using the ReCiPe2006 v1.1 method. Based on the analysis, the highest environmental impacts for all categories (except eutrophication) were from the food consumption in China, followed by the consumption in Japan, Saudi Arabia, Thailand, and India. The major contributors to these impacts were meat, cereals, animal products, and alcoholic beverages. Meat was the highest contributor in all countries except India, because of low meat consumption in India. A calorie intake analysis was also conducted, which showed reductions in environmental impacts by shifting towards calorie-adequate and non-environmentally intensive diets in Thailand, China, Japan, and Saudi Arabia. Therefore, a reduction in the consumption of meat, cereals, animal products, and alcoholic beverages could therefore enhance the environmental sustainability of food consumption.

Climate change has threatened global security of ecosystems, human health and natural resources. These threats have increased demand for various mitigation technology solutions as well as effective strategies for adapting to anticipated impacts. Green infrastructure (GI) technologies such as green roofs and urban forestry are viewed as ones of the best climate adaptation strategies in cities. This study aims to develop a framework for climate change mitigation and adaptation (CCMA) in cities by using green infrastructure technologies. The framework is established by integrating existing green infrastructure frameworks with indicators from green building rating systems (LEED 2009, BCA Green Mark 4.0, CASBEE, and TREES-NC 1.0). The climate change mitigation and adaptation framework addresses benefits from applying different GI technologies as well as limitations in existing rating systems and the green infrastructure applications. This framework will guide researchers, professionals, and decision-makers to effectively integrate climate change mitigation and adaptation in urban planning and development.

Modern pig production contributes to many environmental problems that relate to manure, especially in areas with highly intensive production systems and in regions like Asia where the regulative control is not effective. Therefore, the objective of this study was to use three different pig diets varying in dietary protein, fibre and fat as representative for Danish (DK), Thai (TH) and Vietnamese (VN) pig production to develop and evaluate different approaches to predict/calculate excretion from growing pigs in comparison with the experimentally determined values.Nine female growing pigs were used in a digestibility and balance experiment. Excretion of dry matter (DM), nitrogen (N), phosphorus (P) and carbon (C) of the experimental diets were determined.Due to the highest dietary fibre content, VN had the lowest digestibility of N, P and C (73, 49, and 73%, respectively) compared with the DK and TH pig diets. From the known diet composition using standard table values on chemical and nutrient digestibly, high accuracy (bias) and low variation was found and the results could be used for prediction on chemical composition and excretion in faeces and urine in growing pigs. Calculation based on standard values regarding nutrient retention in the pig body as used in the Danish manure normative system (DMNS) showed likewise to be quite useful for quantifying the total excretion of N and P.Overall, the results demonstrate that simple models that require cheap and normally available information on dietary nutrients can give useful information on nutrient excretion in growing pigs.

The objective of this study was to examine the potential of digestibility improving enzymes to reduce greenhouse gas (GHG) emissions in broiler production. The product examined was a new enzyme called Axtra XAP, developed by DuPont, Danisco Animal Nutrition. Two scenarios were compared: one where Axtra XAP was not included in the diet and one where Axtra XAP was included in the diet. Axtra XAP facilitated higher inclusion rates of cheaper (and possibly more environmentally friendly) feed ingredients that have a lower nutritional value in the diet. Axtra XAP’s environmental improvement potential was documented through a Life Cycle Assessment (LCA) by applying a consequential approach including indirect land use changes (ILUC). The findings showed that Axtra XAP could reduce GHG emissions from broiler production by 5%. A sensitivity analysis was conducted to assess the robustness of the results and it showed that the result varied substantially. The most important parameters were the inclusion or exclusion of ILUC and changes in the feed formulation.

Framework for LCI Modelling towards Green Logistic Systems

In 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.

Skallerup Klit is a Danish holiday center certified as CO2 neutral. <br/>They use this label for branding as them selves as the first CO2 neutral holiday <br/>center in Denmark. There are reasons to question how ambitious “CO2 <br/>neutrality” as a strategy is, because this goal can be reached rather easily by <br/>offsetting and without making actual emission reductions. Therefore the purpose <br/>of this study is to present recommendations on how Skallerup Klit can <br/>build up their business strategy using Carbon Footprint (CFP) as a tool. The <br/>CPF is calculated and assessed by using financial data in an Input-output <br/>LCA. For the LCA the system boundaries of the assessment of Skallerup <br/>Klit´s CFP are defined to include both direct and indirect emissions from the <br/>supply chain and from transportation and food eaten at the holiday center. <br/>Scenarios are conducted to illustrate where the greatest emission reductions <br/>are possible and the results are then used to make recommendations on how <br/>Skallerup Klit can build up their business strategy on future CO2 reduction <br/>initiatives.

Intensive pig productionmaybe a hazard to the environment due to plant nutrient leakage and losses. To facilitate efficient and sustainable manure management and reduce oversupplying of crops with nutrients, there is a need for precise assessment of nutrient content in manure and manure excretion. This study has developed algorithms for predicting the amount of excreta and manure content of nitrogen (N) and carbon (C). Data compiled from 285 digestibility andNbalance experimentswith growing-finishingpigs diets fed diets varyingwidely in chemical compositionwereused toestablish algorithms. The main input variables were analysed nutrients contents together with intake of drymatter and digestibility of organic matter (diOM). The accuracy and prediction power of the obtained prediction equationswere testedwith another dataset consisting of 116 digestibility and N balance experiments with varying chemical compositions. Prediction equations related to Cwas tested using 26 digestibility experiments. The dietary fibre (DF) fractions like crude fibre, non-starch polysaccharides (NSP), analysed DF and calculated dietary fibre (cDF) were all highly negatively correlated to digestibility and positively tomanure output.

However, the equations became more precise when dry matter intake or animal body weight was added as independent variable. For urine N equations, the dietary protein intakewas the best predictor. The partitioning of N between faeces and urine was related to the concentration of cDF with a shift in N excretion in urine to N excreted in faeces as more carbohydratewas fermented. The ratio of C/N in faeceswas depending on cDF in the diet. Thewide variation in the diets included in the predictions ensures that the equations also are relevant and applicable in developing as well as developed countries as a useful tool for efficient handling and use of manure nutrients in practice. © 2008 Elsevier B.V.

Waste Management & Research The Journal for a Sustainable Circular Economy · 2009

Improper management of pig manure has resulted in environmental problems such as surface water eutrophication, ground water pollution, and greenhouse gas emissions. This study develops and compares 14 alternative manure management scenarios aiming at energy and nutrient extraction. The scenarios based on combinations of thermal pretreatment, anaerobic digestion, anaerobic co-digestion, liquid/solid separation, drying, incineration, and thermal gasification were compared with respect to their energy, nutrient and greenhouse gas balances. Both sole pig manure and pig manure mixed with other types of waste materials were considered. Data for the analyses were obtained from existing waste treatment facilities, experimental plants, laboratory measurements and literature. The assessment reveals that incineration combined with liquid/solid separation and drying of the solids is a promising management option yielding a high potential energy utilization rate and greenhouse gas savings. If maximum electricity production is desired, anaerobic digestion is advantageous as the biogas can be converted to electricity at high efficiency in a gas engine while allowing production of heat for operation of the digestion process. In conclusion, this study shows that the choice of technology has a strong influence on energy, nutrient and greenhouse gas balances. Thus, to get the most reliable results, it is important to consider the most representative (and up-to-date) technology combined with data representing the area or region in question.
