Many people may be surprised by the number of chemicals that they are exposed to through
everyday household products．
In a study 25 women had their homes and bodies tested for 89 environmental pollutants-including
pesticides (杀虫剂) and chemicals found in plastics and cleaning products．On average 20 chemicals
were found on their bodies or in their homes．
Much is unknown about the possible health effects of chemicals in everyday household products．
But certain chemicals-like phthalates (邻苯二甲酸盐) found in plastics-have been linked to potential
health risks,including higher risks of certain cancers,though the evidence mainly comes from research
on lab animals．Other household chemicals are known to harm the skin,eyes and airways-and may
worsen asthma (哮喘)．Many more chemicals found remain untested．
Chemicals likely come from a range of sources,so it is not always clear how to reduce people's
exposure,according to Dr．Rebecca Altman,the lead researcher on the new study．"However," she
said,"there are still measures people can take．"
In the original study,she noted,women were given advice based on the particular chemicals they
were exposed to-such as using fragrancefree washing liquid and personalcare products．
For the current study,Altman and her colleagues interviewed two dozen women who'd taken part in
the previous study to see how they would react to information about their household chemical exposures．They found that the women were generally surprised at the range of chemicals found in their homes and
bodiesThey were also surprised that even some banned things were found．
With many questions about the health effects of household chemicals unanswered,some experts worry
that giving people information about their everyday exposures will cause unnecessary fear．However,the
researchers found that the women in their study were typically not alarmed,and instead wanted "more
rather than less" information on the issue．
