Journal ArticleDOI
Highly sensitive and rapid method for determination of fluoride ion concentrations in serum and urine using flow injection analysis with a fluoride ion-selective electrode.
Kazuyoshi Itai,Humio Tsunoda +1 more
TL;DR: An apparatus for flow injection analysis (FIA) was developed to measure very low fluoride ion concentrations (<1 micromol/l), and the results of determination in the NIST Standard Reference Material of urine, SRM 2671a, agreed with the certified values.
Journal ArticleDOI
Effect of matrix modifier and furnace material on the determination of traces of fluoride by electrothermal molecular absorption spectrometry of aluminum monofluoride
TL;DR: In this paper, the effects of the graphite-furnace material on AlF absorbance were investigated, and the maximum sensitivity (4.2 μg ml−1 fluoride for 0.0044 absorbance with a 10μl injection) was obtained with synthetic carbon.
Journal ArticleDOI

Journal ArticleDOI
Organic solvent exposure in small scale industries in north-east Japan.
Masayuki Ikeda,Takao Watanabe,Miyuki Kasahara,Sigetoshi Kamiyama,Hideyoshi Suzuki,Humio Tsunoda,Shigenao Nakaya +6 more
TL;DR: Exposure to organic solvent vapors was investigated in 40 unit workplaces in 16 small-scale industries in north-east Japan in which synthetic urushi lacquer was applied to produce non-metal tableware and exposure did not exceed the current occupational exposure limit in all the cases except for two workers, who were excessively exposed due to the generation of dense vapors in automated spraying process.
