Final waste disposal sites have a negative image of fostering various kinds of pollution, increased traffic volume, noise by trucks and bulldozers, and aggravated living conditions. These concerns indicate that social factors, such as waste landfills' public image, must be considered along with physical factors when locating the final waste disposal sites.  This paper presents a method for determining an optimal site from the two perspectives of physical and social factors. First, we estimate spatial distribution for physical factors using various costs for waste disposal and land prices. Secondly, using results of a survey, we investigate the relationship between cognition of final waste disposal site and age group as covariates and estimate spatial distribution for social factors from the spatial distribution for the age group.","PeriodicalId":285932,"journal":{"name":"Journal of Environmental Science for Sustainable Society","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121308391","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}

Soil amended with 2% normal biochar, 2% functional biochar (with a high NO 3 -N adsorption capacity of 20 g N kg -1 ) or no addition was adjusted at 60% water holding capacity, conditioned with 100 mg N-NO 3 kg -1 dried-soil and aerobically incubated at 25 o C, 30 o C or 35 o C for 21 days. N 2 O and CO 2 emissions were measured on days 1, 3, 5, 7, 14 and 21. Results showed that the addition of normal biochar caused more CO 2 emission but less N 2 O emission compared to the functional biochar application. At 25 o C, biochar amendment had a neutral or positive effect on N 2 O and CO 2 emissions. At 35  C, biochar amendment reduced N 2 O and CO 2 emissions compared to the control. However, there was little difference in N 2 O and CO 2 emissions among biochar treatments. In addition, with increasing temperature, a positive correlation between temperature and N 2 O and CO 2 emissions with the non-biochar amendment and a negative correlation between temperature and N 2 O with the biochar treatments were observed. This is because temperature probably affects the rate of microbial processes mediating respiration and denitrification and the soil-biochar mixture’s mobilization of N","PeriodicalId":285932,"journal":{"name":"Journal of Environmental Science for Sustainable Society","volume":"207 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131846500","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}

Harashima","doi":"10.3107/JESSS.1.33","DOIUrl":"https://doi.org/10.3107/JESSS.1.33","url":null,"abstract":"While the loadings of nitrogen (N) and phosphorus (P) are enhanced by the human activities, dissolved silicate (DSi) supplied by natural weathering of minerals tends to be trapped in the eutrophicated still waters such as dammed reservoirs, which are also increasing globally. The consequent change in the N: P: Si stoichiometric ratio of the river water flowing into the coastal sea may be advantageous to flagellates (nonsiliceous and potentially harmful) but not to diatom (siliceous and mostly benign). This is the \"silica deficiency hypothesis\". We try to develop it further to the \"extended silica deficiency hypothesis\" as follows. While the diatoms effectively draw down the substances from the upper layer with their sinking after the spring bloom (biological pump), other algae do not. This will cause the retention of the surplus nutrients and biogenic substances in the upper layer and lead further to eutrophication of upper layer substantially. To verify this hypothesis, a simplified marine ecosystem model was developed taking the nutrient stoichiometry and differential behaviors of algae into account based on the comparison with the existing field monitoring results of four aquatic continua, where various types of silica decline are uncertain. Although, this study is still in the stage of improvement, the preliminary results infer that above hypothesis could be verified with the consideration of the behavioral characteristics of algae as well as the stoichiometric consideration. Sinking response to the nutrient depletion, which is specific to each algal group, is one of possible factors.","PeriodicalId":285932,"journal":{"name":"Journal of Environmental Science for Sustainable Society","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132127238","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}

Shikazono","doi":"10.3107/JESSS.2.1","DOIUrl":"https://doi.org/10.3107/JESSS.2.1","url":null,"abstract":"Four sequential chemical extraction schemes for metal analysis (a 4-step modified protocol originally proposed by the Standards, Measurements and Testing Programme (SM&T - formerly BCR) of the European Union, Tessier and Hall 5-step procedures and 6-step Grimalt's scheme) were compared. Each procedure was applied to four sediment samples collected from two rivers, Nakagawa (NR) and Tamagawa (TR), Tokyo, Japan. Additionally, a certified marine sediment reference material (JMS-1) was also extracted for the comparison. To evaluate the partitioning of metals among different geochemical forms, the concentration of chromium (Cr), copper (Cu), nickel (Ni), lead (Pb) and zinc (Zn) were measured by Zeeman-corrected atomic absorption spectrometry. Other major elements and mineralogy of sediments were also determined on bulk prior to extracting by X-ray fluorescence (XRF) and X-ray diffraction (XRD) analysis, respectively, which allowed qualitative correlation between the fractionation results obtained and the presence of defined geochemical phases. The total concentrations of metals were determined after strong acid attack and the analytical precision was verified by using JMS-1. Significant proportions of elements were found in non-residual fractions among the schemes (average 83, 91, 76, 93 and 59% for Cr, Cu, Pb, Zn and Ni, respectively) in the more anthropogenically impacted NR sediments. The highest mobility was observed for Pb and Zn among the four schemes while the lowest was for Cr and Ni. Results of the comparison among the total metal levels for the four schemes based upon the sum of sequential extraction steps for each element showed significant differences for Cr, Ni and Zn. On the other hand, the sum of non-residual phases of the four schemes showed no significant differences for Cr, Cu and Zn but the SM&T and Hall schemes showed significant differences from others for Pb and Ni, respectively. Generally, good recoveries were achieved with the Hall scheme (range 92-109%) and the Fe-Mn oxides occlued phase of this scheme was the most effective owing to the high tendency to extract metals. In addition, Grimalt scheme produced the lowest recovery of Cr and the concentrations of residual fraction of other elements were also lower.","PeriodicalId":285932,"journal":{"name":"Journal of Environmental Science for Sustainable Society","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129587832","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}

The opening and closure of stomata are regulated by the integration of numerous environmental signals and endogenous hormonal stimuli. In response to drought stress, plants synthesize a hormone, abscisic acid (ABA), which triggers the signal transduction in the guard cells and induces stomatal closure that prevents water loss by transpiration. Methyl jasmonate (MeJA) is a phytohormone that regulates various physiological processes and mediates plant defense responses. Similar to ABA, MeJA plays a role in the induction of stomatal closure. Glutathione (GSH; γ-glutamylcysteinyl glycine) is an abundant, ubiquitous, and non-enzymatic antioxidant that has significant functions in the growth, development, defense systems, signaling, and gene expression in plants. In recent years, many studies have shown that GSH is involved in the ABA- and MeJA-induced stomatal closure. In this study, we outline the involvement of GSH in the stomatal closure and discuss how GSH regulates ABA signaling and MeJA signaling in the guard cells.","PeriodicalId":285932,"journal":{"name":"Journal of Environmental Science for Sustainable Society","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128555238","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}
