Título The industrial hygiene significance of small air ions
Información bibliográfica Oct. 1981, Vol.42, No.10, p.759-762. Illus. 16 ref.
Resumen An ion mobility discriminator and analyser was used to survey small air ion levels at an electronic assembly production facility in response to symptoms of unknown origin which were common both to psychogenic and ion imbalance illnesses. The positive to negative charge ratio was 1.35 in outside air, 1.21 in office areas and 1.06 in problem production areas. The ion concentration was increased by 10-40% above outside levels in areas where electrostatic precipitators or ion sources were present. Reductions in ion levels were found in areas with relative humidity ≤5%. Ion concentrations were also lower in a laminar flow room, which had high-efficiency particulate filters, and the charge ratio changed to 0.55. No clear-cut association between ion concentration or charge ratio and illness was found.
