体操训练设施中含有大量的聚氨酯泡沫塑料，这种材料通常含有五溴二苯醚等添加剂阻燃剂。虽然对人类接触阻燃剂的调查主要集中在普通人群，但体操运动员和某些职业群体可能会出现比背景暴露更高的情况。我们的目标是比较体操运动员和普通美国人的五溴二苯醚的身体负荷，并表征健身器材、空气和粉尘中的阻燃剂水平。我们从美国东部一家健身房招募了11名18-22岁的大学生体操运动员。体操运动员血清中BDE-153的几何平均浓度(32.5 ng/g脂肪)是美国普通人群的4-6.5倍。与训练前相比，训练后手巾样本中的五溴二苯醚、TBB和TBPH的中位数浓度增加了2-3倍，这表明体操运动员在训练中接触到了这些阻燃剂。健身房空气和粉尘中的五溴二苯醚、TBB和TBPH的GM浓度比居民区高1-3个数量级。我们的发现表明，与普通美国人相比，这些大学体操运动员暴露在五溴二苯醚阻燃剂中的次数更多，而且体操运动员也可能更多地暴露在聚亚安酯泡沫中使用的其他添加剂阻燃剂中，如TBB和TBPH。
Gymnastics training facilities contain large volumes of polyurethane foam, a material that often contains additive flame retardants such as PentaBDE. While investigations of human exposure to flame retardants have focused on the general population, potentially higher than background exposures may occur in gymnasts and certain occupational groups. Our objectives were to compare PentaBDE body burden among gymnasts to the general U.S. population and characterize flame retardants levels in gym equipment, air and dust. We recruited 11 collegiate female gymnasts (ages 18–22) from one gym in the Eastern U.S. The geometric mean (GM) concentration of BDE-153 in gymnast sera (32.5 ng/g lipid) was 4–6.5 times higher than general U.S. population groups. Median concentrations of PentaBDE, TBB and TBPH in paired handwipe samples were 2–3 times higher after practice compared to before, indicating the gymnasts contacted these flame retardants during practice. GM concentrations of PentaBDE, TBB and TBPH were 1-3 orders of magnitude higher in gym air and dust than in residences. Our findings suggest that these collegiate gymnasts experienced higher exposures to PentaBDE flame retardants compared to the general U.S. population and that gymnasts may also have increased exposure to other additive flame retardants used in polyurethane foam such as TBB and TBPH.
