This study proposed country-specific characterisation factors (CFs) for Thailand by modifying the Thai Spatially Differentiated Life Cycle Impact Assessment (ThaiSD) method and introducing monetary conversion factors to express environmental impacts in Thai Baht. Five impact categories were fully parameterised, including fine particulate matter formation (PMF), human toxicity (both cancer and non-cancer) (HT c and HT nc ), freshwater ecotoxicity (FET), and water scarcity (WS). Other spatialised CFs were selected from regionalisation models in ReCiPe2016 and IMPACT World+. When comparing the use of country-specific CFs with global average, the impact scores for PMF, HT c , HT nc , FET, photochemical ozone formation and terrestrial acidification demonstrated notably different levels, ranging from ±25 to ±50 %. The developed method was then applied to assess environmental impacts and costs of Thailand's transport sector, encompassing freight and passenger transport across roadway, railway, waterway, and aviation. Climate change (CC) was significantly attributed to human health and ecosystem quality impacts, while the major contributor to resource scarcity impact was fossil resource scarcity (FS). In some scenarios, non-exhaust emissions, particularly from freight trucks, accounted for 40–60 % of the total PMF impacts. environmental costs of freight and passenger transport in Thailand were 0.08–3.64 Thai Baht per tonne-kilometre and 0.01–0.81 Thai Baht per passenger-kilometre, respectively. Among transport modes, trains were found to be the most environmentally favourable option for both passenger and freight transport, while aviation had the highest environmental impact for freight transport. In contrast, passenger aviation had a comparable environmental burden to passenger cars due to optimised occupancy rates. Despite the efficiency of modern internal combustion engine vehicles (ICEVs), particularly Euro 5 and 6, employing blended biodiesel was less effective in comp

environmental impacts of small scale industries are still not well investigated, especially for estates where multiple small scale industries are clustered causing cumulative effects potentially impacting most vulnerable groups. This study aimed to investigate the concentrations of heavy metals (Mn, Fe, Ni, Cu, Pb, Al, Zn, and Cr) and the metalloid (As) in surface soils near the intensely active small-scale industrial area in Thailand, assess the contamination levels in the co-located child care center, and estimate potential human health risks from exposure to the heavy metals. Surface soil heavy metal(loid) elements were evaluated across a background area, area near main roads, a small-scale industrial area, and a child care centre. The concentrations of Al were found be the highest at all investigation sites, with the most elevated concentrations observed in the small-scale industrial area. The concentration of Pb in the industrial area reached 1176 mg/kg, exceeding the national standard and acceptable limit. Moreover, the contamination level for Cu, Pb, and Zn in the industrial area imply a considerable risk with enrichment factor EF > 40, and geo-accumulation index Igeo ≥5. Heavy metal levels (Ni, Cu, Pb) in the soil near the road and the child care center were similar, suggesting shared contamination sources. Conversely, Al, Zn, As, and Cr in the child care center had slightly higher concentrations than near the road but lower than the small-scale industrial area, indicating potential industrial influence on metal levels within the child care center. The principal component analysis showed Mn and Fe distributed in the background, while As, Pb, Ni, Cu, Al, Zn, and Cr accumulated in the small-scale industrial area. The findings indicate that small-scale industrial activities contribute to elevated levels of heavy metals in the soil, particularly within the child care center, posing significant ingestion risks, especially for children (HI > 1).

In this study, integrated geostatistical techniques were applied to appraise the groundwater quality for various purposes in the Lower Anayari Catchment (LAC), Ghana. Physico-chemical and trace metals were analysed for 41 groundwater samples. Groundwater in LAC was generally found to be moderately hard to fresh and the information entropy-based groundwater quality index (IEGQI) ranked approximately 80.49% of the groundwater as excellent. Partial Least square regression analysis suggests that PO₄³⁻, As, Cd and Fe are important parameters for the prediction of IEGQI values. The irrigation water quality index (IWQI) suggest that 2.44% of groundwater in LAC is suitable for moderate permeability soils, 65.85% for moderate to high permeability soils and 31.71% for moderate to high salt tolerance plants. The LSI and RSI indices rate groundwater in LAC to be aggressive water with a high probability of being corrosive to metals, depending on the levels of dissolved oxygen present. © 2022 The Authors

Source water quality deterioration from microbial contamination is a severe problem confronting drinking water suppliers worldwide and has been addressed in the widely adopted water Safety Plan framework to ensure the reliability and provision of high-quality drinking water. Microbial source tracking (MST) is used to examine different microbial pollution sources via specific intestinal markers for humans and different types of animals. However, the application of MST in tropical surface water catchments that provide raw water for drinking water supplies is limited. We analyzed a set of MST markers, namely, three cultivable bacteriophages and four molecular PCR and qPCR assays, together with 17 microbial and physicochemical parameters, to identify fecal pollution from general, human-, swine-, and cattle-specific sources. Seventy-two river water samples at six sampling sites were collected over 12 sampling events during wet and dry seasons. We found persistent fecal contamination via the general fecal marker GenBac3 (100% detection;2.10–5.42 log10 copies/100 mL), with humans (crAssphage;74% detection;1.62–3.81 log10 copies/100 mL) and swine (Pig-2-Bac;25% detection;1.92–2.91 log10 copies/100 mL) comprising the major and minor contamination sources, respectively. Higher microbial contamination was observed during the wet season (p © 2022, The Authors. All rights reserved.

The spatially differentiated environmental impacts and associated costs of technological improvement and circular agricultural practices in sugarcane production were assessed. Analysis of the cause-effect relationship between the key processes and substances each helped develop alternative scenarios for impact reduction. PM 2.5 emissions contributed to 92 % of the total human health impacts from open burning of field residues. Freshwater ecotoxicity, mainly due to ametryn emissions from pesticide application, contributed to 47 % of the total damage to the ecosystem. The environmental costs were 116 % higher than the value of sugarcane production, signifying the critical importance of adopting alternative pathways that provide economic benefits from environmental cost reduction compared to the production value. Scenarios considering green cane harvesting and waste management approaches demonstrated high potential for total impact reduction of 99 % and 97 %, respectively, and economic gains of 202 and 225 billion THB, respectively (5.76 and 6.42 billion USD, respectively). The economic benefits of waste utilization were 137 % higher than the value of sugarcane production, demonstrating the potential benefits of product substitution to help mitigate impacts. The core findings highlight the significance of the PM 2.5 impact-related external costs and underscore the benefits of adopting green cane harvesting in conjunction with on-field waste utilization to mitigate the impact of open burning and produce value-added products. Technological improvement and circular agricultural practices coupled with valuation of spatially differentiated impacts can provide useful and more accurate information to policymakers, to prioritize the implementation of mitigation strategies for enhancing the environmental sustainability of sugarcane production.

This study investigated microplastics (M.P.s) in mostly used commercial sea salts from Bangladesh. The presence of M.P.s in the 18 sea salt bands was 100%, where the mean M.P.s abundance was 471.67 MPs/kg: ranging between 300 to 670 MPs/kg. The maximum number of M.P.s accounted for in the 300-1500 µm size class was significantly higher than the 1500-3000 µm and 3000-5000 µm size class. The most dominant color was black. Fibers and foams were the dominant shapes. The highest number of M.P.s was 41%, obtained from coarse salt grains. Four types of polymers were mainly identified from the analyzed samples: PP, PE, PET, and PA. The mean polymer risk index value among these sea salts was 539 to 1257. The findings of this study can be helpful for consumers, salt industries, and policymakers to be aware of or reduce M.P. contamination levels in sea salts during production and consumption. © 2023, The Authors.
