Asthma rates have been increasing in children over the last several decades. Risk of bronchial obstruction in children under 2 years was found to be directly related to the amount of plasticizer-emitting material present in the home, particularly PVC flooring.(33) Wheezing in childhood has shown a strong association with use of synthetic bedding.(38) A very recent epidemiological study in children aged 2-8 yrs linked phthalates to asthma and allergies: those with asthma had higher levels of DEHP in dust collected from their bedrooms, and those with allergies had higher levels of BBzP in their bedroom dust.(75) Risk of asthma is increased in pre-term babies on ventilators exposed to DEHP via inhalation through PVC respiratory tubing.(34) In adult men, decrements in respiratory function have been associated with some urinary phthalates.(29) Several phthalates, especially DEHP, are present in vapor form in indoor air and in house dust,(27,28,32) Researchers have proposed a specific mechanism whereby inhaled DEHP leads to asthma.(32)
