We measured arsenic concentrations of the toenails using inductively coupled plasma mass spectrometry. In addition, we examined the association of arsenic levels with lifestyles and dietary habits, including the consumption of fish, seaweed, and rice. The mean toenail arsenic level was 0.41 ppm (95% confidence interval, 0.36-0.47), which was about 3-fold higher than those observed in other populations of mainland Kagoshima. Arsenic levels were elevated among current smokers (mean = 0.65; 95% confidence interval, 0.32-1.29) when compared with non-smokers (mean = 0.40; 95% confidence interval, 0.34-0.46), and among the residents consuming 4 bowls or more, of rice every day (mean = 1.97; 95% confidence interval, 0.25-15.75) when compared to residents consuming 3 bowls or less (mean = 0.39; 95% confidence interval, 0.34-0.45). Sex, age, alcohol intake, fish consumption, or seaweed consumption was not associated with toenail arsenic concentration. Further studies seem warranted to examine the cause of relatively high arsenic levels in our study area.","PeriodicalId":87178,"journal":{"name":"Environmental sciences : an international journal of environmental physiology and toxicology","volume":"13 3","pages":"149-60"},"PeriodicalIF":0.0,"publicationDate":"2006-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"26176422","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 newly produced diet (FD5) was formulated with defatted rice bran and casein, and did not contain any soybean meal or fish meal. Phytoestrogen contents (genistein, daidzein, equol, and coumestrol) of FD5 were measured by liquid chromatography-mass spectroscopy/mass spectroscopy (LC-MS/MS) and compared with those of the commercial trout diet (TD) and carp diet (CD). The genistein, daidzein, and coumestrol contents of TD and CD were much higher (5-2000 times) than those of FD5, but equol was detected only in FD5. Estrogenic activity of the fish diets was estimated in vitro by the yeast estrogen-screen assay (YES assay). The estrogenic activity was detected in TD and CD, but not in FD5. The in vivo estrogenic activity of the diets was examined by determining the production of vitellogenin in male goldfish. When male goldfish were fed TD or CD, plasma vitellogenin levels increased, but fish that were fed FD5 maintained low vitellogenin levels. These results indicate that FD5 produced in the present study has a low estrogenic activity, and FD5 would be suitable for the in vivo estrogen activity test using goldfish.","PeriodicalId":87178,"journal":{"name":"Environmental sciences : an international journal of environmental physiology and toxicology","volume":"13 2","pages":"125-36"},"PeriodicalIF":0.0,"publicationDate":"2006-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"26101124","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}

It is thus necessary to estimate the levels of chemical emissions into the environment and to measure working-environment chemical levels in laboratories. However, there are many laboratories in universities using many chemical reagents for their own needs. Hence, it is difficult for universities to quantitate the amount of chemicals on campus, and there is a lack of information about laboratory environment chemical levels. In this study, the material balance of chloroform and dichloromethane (DCM) in Kyoto University was examined, and the emission rates of chloroform and DCM were estimated to be 37-50% and 50-70%, respectively. These chemicals were thought to be volatilized mainly through reduced-pressure distillation. However, it was found that there was a loss of chemicals due to volatility, which researchers were unaware of, such as that during solvent recovery under reduced pressure and volatilization from containers of organic waste liquid. On the other hand, working-environment chemical levels were measured in several laboratories which used chloroform and DCM frequently. Even in such laboratories, the average concentrations of these chemicals were approximately 1 ppm at most measurement points.","PeriodicalId":87178,"journal":{"name":"Environmental sciences : an international journal of environmental physiology and toxicology","volume":"13 4","pages":"219-34"},"PeriodicalIF":0.0,"publicationDate":"2006-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"26356490","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 concentration of 1,3-butadiene and the 1,3-butadiene-exposure-related lifetime excess cancer risk in the general environment and in the vicinity of industrial point sources were estimated using two different types of diffusion models: the National Institute of Advanced Industrial Science and Technology-atmospheric dispersion model for exposure and risk assessment (AIST-ADMER) model ver. 1.0 for the estimation of regional scale concentrations and the Ministry of Economy, Trade and Industry - low rise industrial source dispersion (METI-LIS) model ver. 2.01 for the estimation of local concentrations near industrial sources. The calculated results indicate that the annual mean concentrations of 1,3-butadiene in residential areas are generally less than 0.5 microg/m(3), but in a few area near industrial point sources they exceed 1.7 microg/m(3), corresponding to a lifetime excess cancer risk of 10(-5). Using data on exposure concentrations and cancer unit risk, the lifetime excess cancer risk for persons exposed to 1,3-butadiene in Japan was evaluated. The results indicate that an extremely small number of people have a risk of developing 1,3-butadiene-exposure-related cancer that is greater than 10(-5), while that of most of the population in Japan is between 10(-5) and 10(-6). The total 1,3-butadiene-exposure-related cancer risk in Japan was calculated as 2.0 cases/year. A large proportion of the cancer risk was associated with general environmental areas. However, the individual risks of the population living in the vicinity of industrial point sources were significantly higher than those of the population living in the general environment.","PeriodicalId":87178,"journal":{"name":"Environmental sciences : an international journal of environmental physiology and toxicology","volume":"13 1","pages":"1-13"},"PeriodicalIF":0.0,"publicationDate":"2006-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"26011381","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}

Pharmaceutical laboratory wastewater is one of the most difficult wastewaters to treat because of its high concentration of halogenated organic compounds. We proposed a new cascade process in which two reactors are consecutively combined, carrying out hydrolysis in the first reactor followed by SCWO in the second reactor, for the complete removal of halogenated organic compounds. Dichloromethane was chosen as a representative model of chlorinated compounds. There have been many previous studies on the hydrolysis of dichloromethane, which results in the coproduction of formaldehyde and HCl. However, there has been less investigation on the kinetics of formaldehyde oxidation in supercritical water. In this study, we focus on the oxidation of formaldehyde in supercritical water with and without a catalyst. As a result, formaldehyde can be completely decomposed at 400 degrees C and 25 MPa within a very short contact time in a heterogeneous system with a MnO(2) catalyst.","PeriodicalId":87178,"journal":{"name":"Environmental sciences : an international journal of environmental physiology and toxicology","volume":"13 5","pages":"297-304"},"PeriodicalIF":0.0,"publicationDate":"2006-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"26415317","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}
