Effects of polycylic aromatic hydrocarbons on plasma monoamine neurotransmitters / 重庆医科大学学报

ABSTRACT

Objective:To explore the effect of polycylic aromatic hydrocarbons (PAHs)on plasma monoamine neurotransmitters. Methods:80 healthy adult male coke oven workers were selected from a coke plant of a state-owned steel enterprise,80 controls were selected from the oxygen factory. Concentration of benzo[a]pyrene(B[a])P in the working environment was monitored by high performance liquid chromatography(HPLC)with fluorescence detector. The level of urinary 1-hydroxypyrene(1-OHP)was determ ined by HPLC with fluorescence detector.The plasma noradrenaline(NE),adrenaline(AD),dopamine(DA)and serotonin(5-HT)levels were measured by high performance liquid chromatography (HPLC) with electrochemical detection. Results:In the working environment of B[a]P, concentration in coke oven workers were significantly higher than controls (P
