gallium arsenide monitoring

Biological monitoring of arsenic exposure of gallium

In an attempt to establish a method for biological monitoring of inorganic arsenic exposure, the chemical species of arsenic were measured in the urine and hair of gallium arsenide (GaAs) plant and copper smelter workers. Determination of urinary inorganic arsenic concentration proved sensitive enough to monitor the low-level inorganic arsenic exposure of the GaAs plant workers. The urinary

GALLIUM ARSENIDE 1. Exposure Data

Monitoring of exposure to gallium arsenide by determination of gallium has so far not been used due to the limited availability of analytical methods with sufficiently low detec-tion limits. Instrumental neutron activation analysis (INAA) has been employed successfully for the determination of gallium in ambient air (Kucera et al., 1999) and can therefore be used for the determination of

Gallium arsenide.

Gallium arsenide. Harrison RJ. The demand for high-speed devices for a variety of communications and military purposes has resulted in a growing interest in alternatives to silicon, with particular attention to compounds of groups 3 to 5 on the periodic table. Gallium arsenide has proved to be an ideal substrate material for some uses but is associated with unique health hazards. PMID: 3299776
