Changes in daily life reduce indoor exposure to selected endocrine disruptors in the home environment: a pilot intervention study.

Increasing prevalence of lifestyle diseases raised global awareness about health consequences of human exposure to endocrine disruptors (EDs): synthetic chemicals that mimic natural hormones and affect the biochemical and endocrine balance. As home environment is one of the main sources of the exposure to xenobiotics - especially for pregnant women, infants and young children - health organizations emphasize the need of implementing lifestyle changes to protect human health and child development. The aim of this study was to evaluate the effectiveness of introducing changes in daily life in lowering the exposure to selected EDs in the indoor home environment. Twenty-six healthy volunteers from 9 households from Gdansk (Poland) were enrolled and their home- and lifestyle-related exposure to EDs was analyzed using a designed questionnaire and algorithm. Urine and dust samples were collected before and after introducing the recommended lifestyle changes. The concentrations of selected EDs in the samples were determined using liquid chromatography-electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS). This pilot study confirmed the ubiquity of harmful chemicals in the home environment and the importance of exposure related to a daily routine. Importantly, it proved that lifestyle modifications implemented by participants led to a significant decrease in both, their home-related exposure to EDs, as well as in urine concentrations of these chemicals. It also demonstrated a need for determining EDs exposure and introducing lifestyle changes as a useful tool for prevention of lifestyle-related diseases.
