title: [Determination of arsenic in As2O3-treated esophagoscope-transplant mouse tissue by graphite furnace atomic absorption spectrometry].
abstract: As2O3 was injected into tumour tissue of esophagoscope-transplant mouse. The concentration of As diffusing into other tissues was investigated. A method was proposed for the determination of As in tissue samples of mouse by graphite furnace atomic absorption spectrometry. After wet digestion (water-bath at 80 degrees C) with 2:1:1 (psi) of HNO3-H2SO4-HClO4, the digested tissue samples of mouse were diluted with 0.2% Triton X-100-0.4% AgNO3. The matrix-matching calibration curve of non-interference was established with standard addition method. The relative standard deviation was 3.2%-8.7%. The limit of detection was 1.57 microg x L(-1). The recoveries were 81.7%-105% Arsenic concentrations in mouse liver, kidney, brain, left-chest, and right-chest were determined after injection of arsenic at different times.
