Study ties house­hold chem­i­cals to kid­ney harm

Iran Daily - - Health -

Widely used house­hold and in­dus­trial chem­i­cals may harm the kid­neys, re­searchers say.

These man­u­fac­tured chem­i­cals, called per- and polyflu­o­roalkyl sub­stances, or PFAS, are not biodegrad­able. Peo­ple are ex­posed to them through con­tam­i­nated soil, food, water and air, UPI wrote.

“The kid­neys are very sen­si­tive or­gans, par­tic­u­larly when it comes to en­vi­ron­men­tal tox­ins that can get in our blood­stream,” said study author Dr. John Stan­i­fer of Duke Univer­sity in Durham, NC.

“Be­cause so many peo­ple are ex­posed to these PFAS chem­i­cals, and to the newer, in­creas­ingly pro­duced al­ter­na­tive PFAS agents such as Genx, it is crit­i­cal to un­der­stand if and how these chem­i­cals may con­trib­ute to kid­ney dis­ease,” Stan­i­fer said.

An­a­lyz­ing 74 stud­ies on PFAS, the re­searchers found the chem­i­cals are as­so­ci­ated with poorer kid­ney func­tion and other kid­ney prob­lems. They said it’s par­tic­u­larly con­cern­ing that chil­dren have greater ex­po­sure to these chem­i­cals than adults. The US En­vi­ron­men­tal Pro­tec­tion Agency said PFAS can be found in food pack­ag­ing; stain- and water-re­pel­lent fab­rics; non­stick cook­ware; pol­ishes, waxes, paints and clean­ing prod­ucts; and fire­fight­ing foams. In fish, an­i­mals and hu­mans, PFAS have the abil­ity to build up and per­sist over time. The study ap­peared in the Sept. 13 is­sue of the Clin­i­cal Jour­nal of the Amer­i­can So­ci­ety of Nephrol­ogy. “By search­ing all the known stud­ies pub­lished on the topic, we con­cluded that there are sev­eral po­ten­tial ways in which these chem­i­cals can cause kid­ney dam­age,” Stan­i­fer said in a jour­nal news re­lease. “Fur­ther, we dis­cov­ered that there have al­ready been mul­ti­ple re­ports sug­gest­ing that these chem­i­cals are as­so­ci­ated with worse kid­ney out­comes,” he added.
