Abstract
Despite increasing attention to the occupational risk of firefighters, little is known about phthalate exposure. In our study, we detected mono-isobutyl phthalate (MiBP), mono-n-buthyl phthalate (MnBP), mono(2-ethyl-5-hydroxyhexyl) phthalate (5OH-MEHP), mono(2-ethyl-5-carboxypentyl) phthalate (5cx-MECPP), and mono(2-ethyl-5-oxohexyl) phthalate (5oxo-MEHP) in each urine sample. We detected positive association between MnBP, MiBP, mono-2-ethylhexyl phthalate (MEHP), 5OH-MEHP, 5oxo-MEHP, 5cx-MECPP, mono-isononyl phthalate (MiNP), the sum of low (∑LMWP) and high molecular-weight phthalates (∑HMWP). and Tiffeneau–Pinelli index (the ratio of forced expiratory volume in 1/ forced vital capacity; FEV1/FVC; p = 0.001−0.04) and the percent predicted value (%PV) of FEV1/FVC (p = 0.005−0.05) and negative association between MiNP and peak expiratory flow (PEF; r = −0.31; p = 0.084). We observed a positive association between phthalate metabolites (MnBP, 5OH-MEHP, 5oxo-MEHP, 5cx-MECPP, 2cx-MMHP, ∑LMWP, and ∑HMWP) and waist-to-hip ratio (WHR; p = 0.003−0.09) and body shape index (ABSI; p = 0.039−0.09) and a negative association between MnBP, ∑LMWP, and hip circumference (p = 0.005−0.02). We detected association between concentrations of 5OH-MEHP, 5cx-MECPP, 5oxo-MEHP, and MnBP and consumption of food heating in plastic material in microwave (p = 0.02−0.04) and between probands who ate margarines and vegetable fat packed in plastic containers and concentration of MMP (p = 0.03). Results of multivariate regression indicated that exposure to phthalates could be linked with changing body structure, which subsequently affects values of pulmonary functions in firefighters.This publication has 44 references indexed in Scilit:
