  1. Evaluation of cyanide exposure and its effect on thyroid function of workers in a cable industry.

    Article - En anglais

    A thyroid-hormone evaluation of workers dealing with cyanide compounds in an electroplating process of a cable industry was carried out.

    Serum thiocyanate (SCN) levels of 35 nonsmoking copper-ply employees were assayed by a ferric-chloride color test.

    The mean SCN concentration of these employees was 316 ± 15 mumol/L, which was significantly (P<0.01) higher than that of control subjects (90.8 ± 9.02 mumol/L).

    Serum thyroxine (T4), triiodothyronine (T3), and thyroid-stimulating hormone (TSH) concentrations of exposed workers were compared with those of 35 control subjects.

    Cyanide exposure resulted in a decrease in T4 and T3 concentrations (P<0.05) and an increase in TSH concentration (P<0.05), compared with the control subjects.

    The serum T4 level was found to be negatively correlated (r=-0.363, P<0.05), whereas the TSH level was positively correlated (r=0.354, P<0. 05), with SCN concentration in the exposed group.

    The study suggests that occupational cyanide exposure in the industry impairs thyroid function.
