These compounds have a variety of characteristics such as the ability to repel grease, water, and oil as well as thermal and chemical stability.&nbsp;Because of these characteristics, the usage of these compounds became widespread in applications in non-stick coatings, food packaging, water-repellent clothing, stain-resistant fabrics and carpets, firefighting foams, and cosmetics, to name a few.&nbsp;The same characteristics also cause PFAS compounds to break down very slowly over time and accumulate in our bodies.&nbsp;There are thousands of PFAS chemical variants, adding to the difficulty of studying their impact on health.<\/h2>\n\n\n\n<p>While research is ongoing in evaluating the health impacts of the vast number of manufactured chemical compounds that are found in industry and consumer products, what we do know now is that three of the most researched PFAS compounds (PFOA, PFOS, and PFHxS) have shown adverse health effects in people<sup>1,2,3<\/sup>.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Where are PFAS located and how harmful are they?<\/strong><\/h2>\n\n\n\n<p>PFAS can be found in the environment, food, humans, flora, fauna, and rainwater globally.&nbsp; Exposure routes include air, water, soil, and food. It is estimated that 97% of the US population has PFAS in their blood<sup>4<\/sup>. In a review of the current science by the National Academies of Sciences, Engineering, and Medicine, it was determined that there is sufficient evidence that exposure to certain PFAS compounds can lead to decreased antibody response, dyslipidemia, decreased infant and fetal growth, and increased risk of kidney cancer<sup>5<\/sup>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Identifying contamination in our drinking water and food supply<\/strong><\/h2>\n\n\n\n<p>The broad usage of PFAS compounds has led to concerns about exposure globally through drinking water, the environment, and our food.&nbsp;Detecting PFAS takes specialized equipment and analytical methods. Waters is helping to solve this problem through our technology and software, which provide the sensitivity, specificity, and compound confirmation needed to confidently screen against threats from industrial and agricultural applications in water, air, and soil. Being part of the solution is important. Our analytical technologies and methodologies help scientists and researchers around the world to study the prevalence of PFAS in the environment and food supply. Much of this work was done in response to regulatory requirements that governments across the globe have put in place to begin to understand the risk of exposure to their citizens and monitor the progress of clean-up efforts.<\/p>\n\n\n<style>.kb-image_77154d-92 .kb-image-has-overlay:after{opacity:0.3;}<\/style>\n<div class=\"wp-block-kadence-image kb-image_77154d-92\"><figure class=\"alignleft size-medium\"><img decoding=\"async\" width=\"300\" height=\"200\" src=\"https:\/\/www.waters.com\/blog\/wp-content\/uploads\/xevo-tq-absolute_lab_064_body-300x200.jpg\" alt=\"one scientist standing using an instrument, another female scientist at desk using computer data program\" class=\"kb-img wp-image-6297\" srcset=\"https:\/\/www.waters.com\/blog\/wp-content\/uploads\/xevo-tq-absolute_lab_064_body-300x200.jpg 300w, https:\/\/www.waters.com\/blog\/wp-content\/uploads\/xevo-tq-absolute_lab_064_body-768x511.jpg 768w, https:\/\/www.waters.com\/blog\/wp-content\/uploads\/xevo-tq-absolute_lab_064_body.jpg 1000w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><figcaption>High-performance tandem quadrupole instruments like the Waters Xevo TQ Absolute are used for PFAS research.<\/figcaption><\/figure><\/div>\n\n\n\n<p>The technologies Waters is focused on in this area include:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Sample preparation<\/li><li>Liquid chromatography instruments<\/li><li>Separation columns<\/li><li>Tandem quadrupole mass spectrometry<\/li><li>Quadrupole time of flight mass spectrometry<\/li><\/ul>\n\n\n\n<p>Additionally, in support of regulatory reporting to government agencies, <a href=\"https:\/\/www.eraqc.com\/environmental-industry\/pfas?sig\">Waters ERA &#8211; known as a leader in the environmental testing accreditation market<\/a> &#8211; built out programs for proficiency testing along with certified reference materials which are critical for laboratories to gain PFAS testing accreditation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Understanding behavior and awareness<\/strong><\/h2>\n\n\n\n<p>Recently, we conducted a research survey* of 1,000 adults in the U.S. to better evaluate consumer behavior, understanding of the PFAS chemical compounds that exist in our communities, and the potential impact on our lives.

Waters instruments are helping our customers to identify PFAS at very low levels to study their persistence and toxicity, as governments work to develop plans to remove them from our environment. Through our customer collaboration, we continue to refine and improve our instruments, software, and chemistries that enable scientists and innovators around the world to ensure the safety of food and water.
