色力影響評估。 n-Hexane a widely used organic
solvent, can dissolve non-polar and low
polar organic compounds. Occupational
exposure to n-hexane induces toxicity on the
peripheral nervous system. ACGIH and
OSHA of the United States adopt the value
of 50 ppm and 500 pm as its TLV-TWA and
PEL-TWA respectively. In this report, the
sampling and analysis method, biological
monitoring, color vision effect of n-hexane
are introduced and discussed.
