Consumer products such as shampoos and sunscreens, even ones boosted as safer, may contain potentially harmful chemicals not listed on their labels, according to a study out today that tested dozens of them. Chemicals that【C1】______hormones or affect health were found in all 42 of conventional products sampled, as well as in most—32 of 43—of the alternative products【C2】______as safer, including some by Seventh Generation, the study says. The scientific group studies the【C3】______between the environment and womens health. 'It was【C4】______,' says Julia Brody, co-author of the findings. She says consumers using a typical array of products are【C5】______many harmful chemicals. Seventh Generation, which makes six of the alternative products tested, welcomed the studys goal of e-ducating consumers【C6】______questioned its method. Martin Wolf, its director of product sustainability, says the company【C7】______none of the chemicals the study found in three of its products. 'The fact that trace amounts were found raises questions' about possible cross-contamination in either【C8】______or testing, he says. 'There are so many【C9】______chemicals in this world that theyre finding their way【C10】______everything.' John Spengler, a professor of environmental health at Harvard School of Public Health, who was not【C11】______the study, says the work is 'very important' for improving health concerns and【C12】______companies to possible cross-contamination in products, whether from the supply【C13】______or the packaging. 'You dont want to worry people【C14】______a reasonable extent,' he says, adding that trace amounts of some chemicals may not pose a problem.【C15】______, he says, theres an 'interactive' accumulating effect from broad use of chemicals, 【C16】______its important to look at them as a group. The study, which tested for 66 chemicals and found 55 of them in the products, says sunscreens and fragrant products had the most【C17】______chemicals and some of the highest concentrations. Brody, who says there needs to be a more【C18】______listing and testing of a products ingredients,【C19】______consumers to use fewer products, seek plantbased ingredients and rely on【C20】______water, baking soda and vinegar for cleaning.
