To combat the public health crisis caused by these contaminants, a team of over 50 international scientists and regulators outlined new approaches to manage them in the Zurich Statement on Future Actions on PFAS. One policy recommended was to initiate a reduction and eventual elimination of nonessential uses of the chemicals.<\/p>\n<p>Rather than halting use of PFAS-containing products altogether, a team of scientists and policymakers, including STEEP Director Dr. Rainer Lohmann, and led by Ian T. Cousins from Stockholm University, suggests differentiating products based on necessity of use and availability of manufacturing alternatives. For example, PFAS use in flame resistant clothing made for workers in the oil and gas industry has no current substitutes and is critical for the safety of the workers, unlike dental floss coated with PFAS, which can easily be replaced with PFAS-free alternatives.<\/p>\n<figure id=\"attachment_13401\" aria-describedby=\"caption-attachment-13401\" style=\"width: 364px\" class=\"wp-caption alignleft\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-13401 size-third_column\" src=\"https:\/\/web.uri.edu\/wp-content\/uploads\/sites\/1022\/food-packaging-364x250.jpg\" alt=\"\" width=\"364\" height=\"250\" srcset=\"https:\/\/web.uri.edu\/steep\/wp-content\/uploads\/sites\/1022\/food-packaging-364x250.jpg 364w, https:\/\/web.uri.edu\/steep\/wp-content\/uploads\/sites\/1022\/food-packaging-194x133.jpg 194w, https:\/\/web.uri.edu\/steep\/wp-content\/uploads\/sites\/1022\/food-packaging-150x103.jpg 150w, https:\/\/web.uri.edu\/steep\/wp-content\/uploads\/sites\/1022\/food-packaging-500x343.jpg 500w, https:\/\/web.uri.edu\/steep\/wp-content\/uploads\/sites\/1022\/food-packaging.jpg 700w\" sizes=\"auto, (max-width: 364px) 100vw, 364px\" \/><figcaption id=\"caption-attachment-13401\" class=\"wp-caption-text\">Food packaging is an example of a <em>\u2018nonessential\u2019<\/em> item.<\/figcaption><\/figure>\n<p>In their paper \u2014 <a href=\"https:\/\/pubs.rsc.org\/en\/content\/articlelanding\/2019\/EM\/C9EM00163H#!divAbstract\"><em>The concept of essential use for determining when uses of PFASs can be phased out<\/em><\/a> \u2014 the authors sorted products and application containing PFAS into categories of \u2018<em>nonessential<\/em>,\u2019 \u2018<em>substitutable<\/em>,\u2019 and \u2018<em>essential<\/em>.\u2019 <em>Nonessential<\/em> uses of PFAS are those in products and applications that are not necessary for health, safety, or the functioning of society \u00ad\u00ad\u2014 such as PFAS in cosmetics.
