    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.
