The potential impact of oil pollution on Thyroid and Parathyroid Hormones in directly exposed workers in Al-Shaiba oil refinery

Abstract

Thyroid hormones are essential for growth, neuronal development, reproduction and regulation of energy metabolism. Hypothyroidism and hyperthyroidism are common conditions with potentially devastating health consequences that affect all populations worldwide. This study aimed to evaluate the  effects of exposure to petroleum gases, vapors and pollutant materials on oil refinery workers in Al-Shaiba / Basra-Iraq. However, samples were collected from male workers Ages from (22 – 55) years and divided into four groups according to their years of experience in the same refinery and compared with healthy control. We highlight It also showed that T4, TSH, and PTH hormone more effected by the heavy metals than T3 hormone in comparison to the healthy control group. It showed that worker with direct exposure of pollution sources for more than 5 years of exposure is more affected with oil refinery pollutant than workers who only exposed for 1-5 years.
