The study also aims to analyze the aerosol optical depth (AOD) in the period from January 1, 2014 to October 15, 2020. The effect of the PM2.5 concentrations on health in 2016 has also been quantified. The results indicate that the daily PM10 value of 50 μg/m3 recommended by the World Health Organization was exceeded on 75% of the monitored days. The morphological analysis of PM10 demonstrated the presence of particles of anthropogenic and geogenic origin. Particles from building activities and secondary aerosol formation were found, as well as particles associated with the resuspension of soil and marine aerosols. In 2016, 718, 1426, and 4295 cases of all-cause mortality, on average, could have been avoided in the MEAL if the annual average of PM2.5 would have decreased from 26.53 μg/m3 to 23.88 μg/m3, 21.22 μg/m3, or 10 μg/m3, respectively. In 2016, 1.58%, 3.14% and 9.47% of all causes are respectively attributed to fine aerosol (PM2.5) over 23.88 μg/m3, 21.22 μg/m3, and 10 μg/m3.

It covers up to 252 hectares by national land and aims to in charge of the essential works of counties, cities and towns of the province. Furthermore, it was the pioneer of urban planning concerned with the development, design of land use and the built environment in Taiwan. Chung Hsing New Village took the case study from Ebenezer Howard's Garden City, included connecting the suburbanization development with compact layouts, low-density development with good public spaces and emphasis on neighborhood unit in the thoughts, to create a functional working environment and public facility as a model of town planning in Taiwan. However, due to the downsizing of the Taiwan provincial government in 1998, most administrative workers were laid off, and yet, the Jiji earthquake damaged lots of buildings in 1999. Despite this, the remarkable value of culture and advanced concept of town planning made Chung Hsing New Village had been listed as cultural landscapes preservation since 12th April 2011, but compare to the other countries’ regulation of cultural landscapes and sustainable environmental preservation framework, the authorities failed to act and lack of big picture caused severe problems like abandoned and ruined, etc. To sum up, this research aims to explore the core value of Chung Hsing New Village environmentally sustainable, follow up with literature review, field investigate and in-depth interview with experts to construct Chung Hsing New Village cultural landscapes.

It is more prevalent on the Bamburi shoreline, which is about 4km long, and has been attributed to anthropogenic and natural processes that interfere with longshore drift depriving the beaches of sediments. Inadequate hazard assessments of the morphological processes on the beaches have made shoreline management interventions impracticable. Hazard vulnerability assessment obtained from the mean beach sediment volume was used to understand the differential and site specific spatial vulnerability of beaches to erosion on the shoreline. Accretion was revealed along Baharini challets - Private home, Whitesands-Sai rock, Papweza-Bamburi villas and Giriama beach-Jambo Ree shorelines, while erosion was experienced at Private home – Severine beach, Severine beach – Whitesands beach, Sai rock - Papweza, Bamburi villas – Kenyatta beach and Kenyatta beach - Giriama beach shorelines. Site specific vulnerability differences and morphological dynamics are evident along the shoreline. Spatial adaptive management strategies, including set back regulations and impact assessments, revegetation of the shoreline and simple engineered protection structures should be adopted and enforced to ensure stability of the shoreline and the beach system.","PeriodicalId":13980,"journal":{"name":"International journal of environmental science and development","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67448944","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Greywater should be treated to complying with the specifications for several purposes such as toilet flush, landscaping irrigation, and agriculture. The treatment efficiency of both MBR and RBC systems was investigated by using a verified mathematical model. The simulation program GPS-X (version 6.0) was used to simulate both MBR and RBC systems. The simulation model for biological treatment for both MBR and RBC systems is based on Activated Sludge Model 1 (ASM1). The experimental data for model calibration and verification for the MBR system were taken from experimental work done at Tubitak, Marmara Research Center, Turkey ATASOY. As well as the RBC proposed model was verified also by using RBC experimental results for a pilot plant according to BABAN. The RBC pilot plant consists of three units, The first is the RBC unit, the second unit is the settling tank and the last unit is the disinfection tank. The results of the MBR plant showed that the removal efficiencies of the greywater were: 95% for COD; 95% for BOD5; 96% for TKN; 92% for NH4+ and 99% for TSS. Whereas, the results of the RBC show that, The BOD efficiency removal was ranged between about 93.0 to 96.0 %, and for the total SS removal was ranged between 84.0 to 95.0 %. The MBR system provides complete nitrification and suspended solid removal. The RBC system provides less nitrification process and suspended solid removal. The effluent of the rotating biological contactors units for the greywater could be reused after filtration and disinfection with minimal cost of operation. The effluent of the membrane bioreactor unit needs only disinfection before reuse.","PeriodicalId":13980,"journal":{"name":"International journal of environmental science and development","volume":"12 1","pages":"107-111"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67448990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work, therefore, aimed to quantify and characterize municipal solid waste generated from Beung Kiat Ngong Ramsar Site and to recommend possible integrated solid waste management strategies for a sustainable waste management. The average daily waste generation was estimated to be 3.6 kg/day and 2.6 kg/day in Thabou village and Kiat Ngong village, respectively. Organic waste appeared to be the biggest component (28%) for Thabou village, while packaging’s dominated waste composition in Kiat Ngong village. Interestingly, high percentage of golden apple shells waste were mismanaged. These had the potential to convert into value-added products such as calcium carbonate (CaCO3). It was found that fresh golden apple shells contained only 24.16±0.48 g/l as CaCO3, while incineration method increased higher CaCO3 products. The result showed that incineration at the temperature of 400 oC gave the highest amount of CaCO3 with the values of 1207.67±9.45 g/l as CaCO3. Based on the resources and the strength of the Ramsar site, the production of value added material from bio-waste could be integrated into waste management strategies along with 3Rs policies implementation.","PeriodicalId":13980,"journal":{"name":"International journal of environmental science and development","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67449771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Personal air sampling was performed for each activity according to the NIOSH 0500 and NIOSH 0600 methods. Based on the results, both powders were uniform spheres with a particle size of 40–60 μm. The total particulate concentration was most significant during the following pre-processing activities: 1) pouring powder into the mixing machine and 2) transferring the powder to the SLS AM machine. The total particulate concentration and respirable particulate concentration were slightly higher for the virgin powder for these activities. In conclusion, the virgin and recycled PA12 powders were both inhalable and respirable, which poses serious health hazards to the SLS AM operators.
