Resumen

GARCIA CUAN, Aracely et al. Determination of polychlorinated biphenyls (PCB's) in workers of a company in the electricity sector. Barranquilla - Atlantic, 2017. Rev. Univ. Ind. Santander. Salud [online]. 2019, vol.51, n.1, pp.23-32. ISSN 0121-0807.  http://dx.doi.org/10.18273/revsal.v51n1-2019003.

Introduction:

Polychlorinated Biphenyls (PCB's) in blood and tests of organic function for evaluation of the health in workers of a company of the electrical sector were determined.

Methods:

We selected 61 company employees Electricaribe S.A. of Barranquilla, 30 exposed to PCB's and 31 unexposed, over 18 years without established pathology and that signed the informed consent. It was analyzed: glycemia, lipid profile, creatinine, blood urea nitrogen (BUN), bilirrubin, alkaline phosphatase, pyruvic and oxaloacetic transaminase, gamma-glutamyl transpeptidase, T3, T4, thyroid stimulating hormone (TSH). For detection of PCB's, a chromatograph HP 5890 series II gas (Hewlett Packard), electron capture detector (EDC) and DB-5 column (30 m x 0.25 mm x 0.25 μm) was used. The data were processed with Minitab 15 software, 95% confidence level.

Results:

It was found that 100% of workers examined showed PCB's values lower than the minimum limit value of detection of the chromatographic method used: 4 μg/L of PCB's, and negative clinical evaluations for any organic damage.

Conclusions:

No significant difference in the results between exposed and unexposed to the PCB's workers.
