level for both subjective and objective eye irritation (blinking frequency and conjunctival redness) due to FA exposure in human volunteers was 615 µg/m3 at a constant exposure level , and 369 µg/m3 ...
. Formaldehyde's well- known toxicity and carcinogenicity and wide spread human exposure has raised public concern over its safety. Formaldehyde can directly enter into the body through environmental exposure ...
exposure An inhalation chamber with 16 L (32 cm × 25 cm × 20 cm) coupled to a nebulizer (Inalamax NS®, Brazil) was used to generate an air stream from an aqueous FA solution. Ambient concentrations of FA ...
a level of endogenous formaldehyde and low concentration exposures are not expected to cause any appreciable increase above background. At some intermediate inhaled concentration, the exposure should lead ...
, volunteers were exposed in 12 groups of two to four persons in a chamber (4.3 × 2.9 × 2.4 m) according to the scheme shown in Table I. The FA exposure concentrations were: 0 p.p.m. (i.e. background level ...
studied the inhalation toxicokinetics of methanol vapor in four female and four male human volunteers during light physical exercise (50 W) in an exposure chamber . The relative uptake of methanol was about ...
, glutaraldehyde, and methyl glyoxal when compared to a clean air control. Consistent results were observed when the protein levels of these cytokines were analyzed. Exposure to 4-OPA significantly elevated IL-8, IL ...
