As the disaster response, spilled oil which was floating on the flood water was recovered by oil absorption sheets. It was hypothesized that soil contamination by spilled oil might be avoided if the oil could be recovered before it contacted to soil. The paddy soil samples collected in oil contaminated area (clean up with oil absorption sheets, n=3), control areas (n=2), and used quench oil (spilled oil from steel mill) were employed for chemicals analysis. The analytical technique of Automated Identification and Quantification Systems with gas chromatography mass spectrometry (AIQS-GC) was applied for Comprehensive Target Analysis (CTA). As the result of chemical analysis, sterols, alkanes, PAHs (including nativeand methylated-PAHs), and other compounds were detected in paddy soil samples. Only alkanes and PAHs were detected from used quench oil. No clear differences were found on alkanes and PAHs concentrations between paddy soils collected in oil contaminated area and control area. On the other hand, contribution of chemicals detected in paddy soils and used quench oil were clearly different. These results indicate that soil contamination by spilled oil could be avoided by the recovering of spilled oil using oil absorption sheets during it was floating on the flood water.","PeriodicalId":15764,"journal":{"name":"Journal of environmental analytical chemistry","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87329514","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}

Phyllostachys edulis from Anan City in Tokushima Prefecture was used in this study. In this method of potassium determination, the electrical conductivity of bamboo was measured after ashing and dissolution in pure water. The optimum bamboo ashing time was determined to be 8 h because the effect of water-soluble or exchangeable phosphorus on the electrical conductivity disappeared after bamboo ashing for ＞8 h and the obtained electrical conductivity was constant. The electrical conductivity and potassium content of various bamboo samples were determined by ICP (Inductively Coupled Plasma) emission spectroscopy and compared. The results showed a significant correlation between them ( p ＜0 . 01 , r 2 ＝0 . 988 ). Moreover, the results indicated that a good calibration curve was obtained for this method. Therefore, the proposed method can be used for the simple analysis of potassium at the field level without the use of expensive analyzers.","PeriodicalId":15764,"journal":{"name":"Journal of environmental analytical chemistry","volume":"64 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84806431","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}

Samples were collected randomly from six (6) different locations/towns in Sagamu Local Government. The samples were analyzed for its physicochemical and bacteriological parameters. The results of the analyses were compared with the permissible limit set by WHO, EPA, Canada, and NIS. It was found that most of the parameters, turbidity 0.08-0.16 with permissible limits of 0.1-5.0, alkalinity 9-17 mg/l with permissible of 5.00 mg/l, Total hardness 3-6 mg/l with permissible limits of <60-100 mg/l, Phosphate 0.12-0.51 mg/l with permissible limits of <5 mg/l, Iron 0.02-0.21 mg/l with permissible limits of <0.03 mg/l, Calcium 2.10-4.80 mg/l with permissible limits of <75-200 mg/l, Nitrate 0.00-2.50 mg/l with permissible limits of <45-50 mg/l, Chlorine 12.8-28.30 mg/l with permissible limits of <250 mg/l were in the expected range of the permissible limits set by WHO, EPA, Canada, and NIS. However, the pH 4.73-6.10 of the sachet water samples tends to be acidic below the expected range 6.5-10.5. The Total Heterotrophic Bacteria count and Enteric Bacteria count tends to be a little lower below the permissible limits, Total Enteric Bacteria 300-480 CFU/100 ml with permissible limits of <500 CFU/100 ml and Enteric Bacteria 280-380 CFU/100 ml. It was recommended that water producing industries should site their raw water site in a safe location free from contamination, the government should involve the participation of equipped private and government hospitals with good laboratory to monitor and report accordingly the situation of all water packaging industries in their vicinity, the government should also involve the participation of genuine and reputable individuals to produce and provide paid pipe borne waters to people in their community and regulatory bodies such as SON and NAFDAC should take responsibility by continually re-assessing the production and packaging quality of drinking water in every community.","PeriodicalId":15764,"journal":{"name":"Journal of environmental analytical chemistry","volume":"198 1","pages":"1-11"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78124062","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}

Our comparison of riffles and pools and our examination of the appropriate places to collect eDNA samples revealed that the detected fish species were not completely consistent between the two kinds of surveys and there was no ecological fea-tures common to detected fish species. Therefore, sampling at multiple locations is expected to reduce detectable fish dropouts. More fish species were detected in the eDNA survey than in the collection survey at all times. However, the results also suggested that the DNA of fish species living upstream may remain at sampling site, and benthic fish species tend to be difficult to detect by eDNA surveys. In addition, the influence of water quality on the characteristics of the survey site were analyzed, since marine species were detected in some river eDNA surveys. The results suggested that domestic drainage is likely to affect the characteristics in winter, when the amount of water is small, and the change in concentration of linear alkylbenzene sulfonic acid and its salts and the change of the ratio of chloride ions may be used as an index of domestic drainage.","PeriodicalId":15764,"journal":{"name":"Journal of environmental analytical chemistry","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89473164","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}

Arsenic concentration in the river water decreased toward the downstream, however, from the Ebino Bridge to the Nagae Bridge, it was diluted by the increase of the river water.

Regarding the amount information, two groups of substances, industrial use substances (substances related to the Chemical Substitution Law and PRTR law) and pesticides, were targeted. Priority substance list was prepared by linking with the toxic judgment value.
