Experts know these substances as endocrine disruptors. They are contaminants that originate from human activity and are not satisfactorily eliminated by water treatment stations. During her doctoral work at the S\u00e3o Paulo State University (Unesp), Botucatu campus, pathologist Marize Solano went beyond simply detecting these chemicals in the water. She analyzed the effects of tap water samples collected in 2010 and 2012 in the city of Campinas, inland S\u00e3o Paulo State, on the reproductive development of female rats. Though slight, the effects indicated an accelerated development of puberty, especially in the case of the samples from 2010. Three days drinking the water \u2013 which contained caffeine, atrazine, and estrone, among other chemicals \u2013 were enough for the researchers to observe increases in uterus weight and endometrial thickness, both indicators of estrogenic response. After a more extended exposure, of 20 days, the rats presented hormonal alterations, especially in levels of the follicle stimulating and luteinizing hormones (<em><i>Endocrine Disruptors<\/i><\/em>, May 2015). The effects observed are still subtle and have been reported only for rodents, but may raise a red flag for humans \u2013 especially considering the prolonged periods during which tap water is consumed during a lifetime.<\/p>\n","protected":false},"excerpt":{"rendered":"Substances found in the tap water of many cities affect hormonal function","protected":false},"author":475,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"categories":[168],"tags":[259,236],"coauthors":[785],"class_list":["post-197039","post","type-post","status-publish","format-standard","hentry","category-technoscience","tag-chemistry","tag-physiology"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/197039","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/users\/475"}],"replies":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/comments?post=197039"}],"version-history":[{"count":0,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/197039\/revisions"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=197039"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=197039"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=197039"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=197039"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
