The conversation highlights how analytical chemistry, environmental engineering, and public health intersect in addressing one of today's most discussed classes of emerging contaminants.</p><h4><strong>Understanding PFAS and Their Significance</strong></h4><h5><strong>The University of Alabama Water Quality Research Center</strong></h5><p>Dr. Leigh Terry is part of the University of Alabama's Center for Water Quality Research. The center operates an analytical laboratory focused on drinking water quality and the detection of contaminants at extremely low concentrations.</p><p>The laboratory specializes in:</p><ul><li>Drinking water analysis</li><li>Organic contaminants</li><li>Emerging contaminants</li><li>PFAS monitoring</li><li>Water quality research</li></ul><p>Their work supports both research initiatives and practical solutions for water utilities and environmental agencies.</p><h4><strong>Why Focus on PFAS?</strong></h4><p>Although PFAS compounds have existed since the 1940s, public awareness has increased dramatically only in recent years.</p><p>According to Dr. Terry, several factors contributed to the rapid growth of PFAS research:</p><ul><li>Increased media attention</li><li>New regulatory initiatives</li><li>Growing evidence of human exposure</li><li>Expanding research opportunities</li><li>Greater understanding of potential health risks</li></ul><p>PFAS are not new contaminants. Rather, society is only beginning to understand their prevalence in the environment and their potential impacts on human health.</p><h4><strong>The Development of Standardized PFAS Methods</strong></h4><p>One major advancement in PFAS analysis has been the development of standardized EPA methods.</p><p>These methods allow:</p><ul><li>Consistent testing procedures</li><li>Comparable results between laboratories</li><li>Regulatory monitoring</li><li>Reliable data interpretation</li></ul><p>Dr. Terry notes that many of these standardized approaches began appearing around 2018–2019, providing a common framework for analytical laboratories and researchers.</p><h4><strong>How Large Is the PFAS Universe?</strong></h4><p>Many people are familiar with PFOA and PFOS, two of the most heavily studied PFAS compounds. However, these represent only a small fraction of the broader PFAS family.</p><p>PFOA and PFOS are often referred to as:</p><ul><li>Legacy PFAS compounds</li><li>Original PFAS contaminants</li><li>Early commercial PFAS chemicals</li></ul><p>The challenge is that even minor modifications to molecular structure create entirely new PFAS compounds.</p><p>Researchers estimate:</p><ul><li>Thousands of PFAS compounds exist</li><li>Some estimates exceed 10,000 compounds</li><li>Exact numbers depend on how PFAS are defined</li></ul><p>Scientific debate continues regarding classification and definition, making precise counting difficult.</p><h4><strong>Why PFAS Are Called "Forever Chemicals"</strong></h4><p>Dr. Terry notes that the phrase "forever chemicals" has become widely used, although she suggests the terminology could benefit from rebranding.</p><p>PFAS persistence results from two key chemical properties.</p><h5><strong>1. Amphiphilic Structure</strong></h5><p>PFAS molecules contain:</p><ul><li>A water-loving (hydrophilic) head group</li><li>A water-repelling (hydrophobic) fluorinated tail</li></ul><p>This unusual combination allows PFAS to partition between:</p><ul><li>Water</li><li>Solids</li><li>Air-water interfaces</li><li>Foam</li></ul><p>Unlike many organic compounds, PFAS can interact effectively with multiple environmental phases.</p><h5><strong>2. Extremely Strong Carbon–Fluorine Bonds</strong></h5><p>The carbon–fluorine bond is among the strongest bonds in organic chemistry.</p><p>As Dr. Terry explains:</p><ul><li>Large amounts of energy are required to break these bonds</li><li>Natural degradation processes are often ineffective</li><li>Destruction can require highly aggressive treatment conditions</li></ul><p>These properties make PFAS extremely persistent in both environmental systems and biological organisms.</p><h4><strong>Toxicity, Regulations, and Environmental Behavior</strong></h4><h5><strong>Understanding PFAS Toxicity</strong></h5><p>One of the biggest challenges in PFAS regulation is the incomplete understanding of toxicity.</p><p>Dr. Terry explains that EPA regulations generally consider three factors:</p><ul><li>Presence in drinking water sources</li><li>Toxicity to humans</li><li>Availability of practical treatment options</li></ul><p>While some PFAS compounds are known to be harmful, many others remain insufficiently studied. Furthermore, PFAS often occur as mixtures rather than individual compounds.</p><p>This creates important scientific questions:</p><ul><li>What is the toxicity of individual PFAS?</li><li>What is the toxicity of PFAS mixtures?</li><li>How should cumulative exposure be evaluated?</li></ul><p>These uncertainties continue to drive active research.</p><h4><strong>What Happens to PFAS in Wastewater Treatment Plants?</strong></h4><p>PFAS do not behave like many conventional contaminants.</p><p>Rather than remaining fully dissolved in water, they often accumulate at interfaces such as:</p><ul><li>Water-solid interfaces</li><li>Water-air interfaces</li><li>Foam layers</li><li>Biological solids</li></ul><p>As a result:</p><ul><li>Some PFAS accumulate in biosolids</li><li>Some partition into foam</li><li>Some remain in treated effluent</li></ul><p>Their distribution depends on wastewater composition and treatment processes.</p><h4><strong>Regulatory Monitoring and Targeted LC-MS Analysis</strong></h4><p>Current EPA regulations focus on targeted analysis of specific PFAS compounds.</p><p>Examples include:</p><ul><li>PFOA</li><li>PFOS</li></ul><p>Drinking water regulations currently establish maximum contaminant levels (MCLs) for these compounds at extremely low concentrations.</p><p>Advantages of targeted LC-MS analysis include:</p><ul><li>Clearly defined analytes</li><li>Established regulatory limits</li><li>High analytical sensitivity</li><li>Reliable quantitation</li></ul><p>However, limitations remain:</p><ul><li>Only a small subset of PFAS is measured</li><li>Many PFAS compounds remain undetected</li><li>Total PFAS burden may be underestimated</li></ul><p>As Dr. Terry notes, targeted analysis provides only part of the overall picture.</p><h4><strong>The Fluorine Mass Balance Problem</strong></h4><p>One of the most important concepts discussed in the interview is fluorine mass balance.</p><p>When PFAS degrade, fluorinated fragments may remain in the environment.</p><p>This creates a critical question:</p><p>Are treatment technologies truly destroying PFAS, or merely transforming them into shorter-chain PFAS compounds?</p><p>To answer this, researchers perform fluorine mass balance calculations using:</p><ul><li>Targeted PFAS analysis</li><li>Fluoride measurements</li><li>Total organic fluorine measurements</li></ul><p>A successful destruction process should ultimately convert PFAS into fluoride ions rather than simply producing smaller PFAS molecules.</p><h4><strong>Advanced Analysis, Treatment Technologies, and Future Directions</strong></h4><h5><strong>Combining Targeted and Bulk Fluorine Measurements</strong></h5><p>Dr. Terry's group complements targeted LC-MS analysis with measurements of total organic fluorine.</p><p>Approaches include:</p><ul><li>Absorbable Organic Fluorine (AOF)</li><li>Extractable Organic Fluorine (EOF)</li><li>Combustion Ion Chromatography (CIC)</li></ul><p>In these methods:</p><ul><li>Organic fluorine is captured</li><li>Samples are combusted</li><li>Released fluoride is quantified</li></ul><p>This provides insight into total fluorinated content, although contributions may originate from sources beyond PFAS, including pharmaceuticals and consumer products.</p><h4><strong>Surprising Findings from Combined Analysis</strong></h4><p>One important finding from wastewater studies was that targeted PFAS measurements accounted for only a small fraction of total organic fluorine.</p><p>Dr. Terry reports that:</p><ul><li>Approximately 4% of measured AOF could be explained by targeted PFAS compounds</li><li>The majority of organic fluorine remained unidentified</li></ul><p>This suggests that environmental fluorine chemistry is considerably more complex than currently represented by routine monitoring programs.</p><h4><strong>Preventing PFAS Contamination in the Laboratory</strong></h4><p>PFAS analysis requires exceptionally strict quality control.</p><p>Dr. Terry's laboratory routinely:</p><ul><li>Tests every new batch of SPE cartridges</li><li>Tests carbon tubes before use</li><li>Uses DI water blanks</li><li>Verifies consumables labeled as PFAS-free</li><li>Collects field blanks</li><li>Monitors analytical blanks throughout workflows</li></ul><p>These practices help prevent contamination from laboratory materials and consumables, a common challenge in ultra-trace PFAS analysis.</p><h4><strong>Current PFAS Treatment Technologies</strong></h4><p>Three technologies currently dominate PFAS removal in drinking water treatment:</p><ul><li>Granular Activated Carbon (GAC)</li><li>Ion Exchange Resins</li><li>Reverse Osmosis (RO)</li></ul><p>Selection depends on:</p><ul><li>PFAS concentration</li><li>Water quality</li><li>Local operating conditions</li><li>Utility infrastructure</li></ul><p>Although many emerging technologies are being investigated, these remain the most widely implemented solutions.</p><h4><strong>Membrane Filtration and Pretreatment</strong></h4><p>Dr. Terry collaborates with colleagues studying membrane-based PFAS treatment.</p><p>Her own work focuses on pretreatment through biological filtration.</p><p>The strategy involves:</p><ul><li>Removing natural organic matter</li><li>Reducing membrane fouling</li><li>Improving membrane performance</li><li>Extending operational efficiency</li></ul><p>This integrated approach demonstrates how multiple treatment technologies can work together to improve PFAS removal.</p><h4><strong>Regional Monitoring Projects</strong></h4><p>The University of Alabama team participates in EPA-supported monitoring efforts along the Gulf Coast.</p><p>Their observations indicate:</p><ul><li>PFAS rarely occur alone</li><li>Multiple PFAS compounds frequently co-occur</li><li>Contamination often originates from identifiable point sources</li></ul><p>Examples include:</p><ul><li>Industrial facilities</li><li>Manufacturing operations</li><li>Military installations</li><li>Carpet manufacturing facilities</li></ul><p>Source identification remains a critical component of environmental monitoring programs.</p><h4><strong>Future Directions for PFAS Monitoring</strong></h4><p>Looking ahead, Dr. Terry sees several opportunities for improvement.</p><p>Desired advances include:</p><ul><li>In situ monitoring technologies</li><li>Portable detection systems</li><li>Reduced analytical complexity</li><li>Lower instrument costs</li><li>Less expensive consumables</li><li>Faster analysis workflows</li></ul><p>Current PFAS testing requires substantial expertise, specialized instrumentation, and rigorous quality control, making widespread implementation challenging.</p><h4><strong>Dr. Terry's Perspective on Long-Term Solutions</strong></h4><p>When asked what major PFAS challenge she would most like to solve, Dr. Terry offered a broader perspective.</p><p>Rather than focusing solely on remediation, she emphasized prevention.</p><p>Her view is that society should:</p><ul><li>Better evaluate chemical toxicity before commercialization</li><li>Assess risks before large-scale deployment</li><li>Reduce introduction of harmful compounds into the environment</li><li>Support utilities tasked with contaminant removal</li></ul><p>She notes that water utilities often bear the responsibility of removing contaminants they did not create, highlighting the need for broader societal and regulatory support.</p><h4><strong>Final Thoughts</strong></h4><p>Dr. Terry encourages consumers to:</p><ul><li>Learn where their drinking water originates</li><li>Read annual water quality reports</li><li>Stay informed about local water quality</li><li>Consider appropriate home filtration where needed</li></ul><p>At the same time, she emphasizes confidence in municipal water systems and the importance of continued investment in water quality research, monitoring, and treatment technologies.</p><h4><strong>Conclusion</strong></h4><p>PFAS remain one of the most complex challenges in environmental chemistry and water treatment. Through advanced analytical methods such as LC-MS/MS, combustion ion chromatography, fluorine mass balance approaches, and large-scale monitoring programs, researchers like Dr. Leigh Terry are helping improve our understanding of these persistent contaminants.</p><p>The interview highlights that solving the PFAS challenge will require a combination of better analytical tools, improved treatment technologies, stronger regulatory frameworks, and a greater emphasis on prevention before contaminants enter the environment.</p><blockquote><p><strong>This text has been automatically transcribed from a video presentation using AI technology.

PFAS in Water: Why We’re Missing 96% of the Problem

<p><strong>This study evaluates an immobilized enzyme reactor (IMER) containing peptide N-glycosidase from </strong><i><strong>Rudaea cellulosilytica</strong></i><strong> (PNGase Rc) for rapid online deglycosylation of intact glycoproteins. Human glycoproteins and therapeutic antibodies were used as model substrates to assess reactor performance.</strong></p><p>The PNGase Rc IMER efficiently removed complex sialylated and core-fucosylated glycans, simplifying protein characterization and glycosylation-site analysis. The approach offers a fast and effective solution for bioanalytical workflows, biopharmaceutical quality control, and stability testing of therapeutic proteins.</p><blockquote><h4><strong>The original article</strong></h4><h4><a target="_blank" rel="noopener noreferrer" href="https://pubs.acs.org/doi/10.1021/acsomega.6c00577"><strong>Online Deglycosylation of Monomeric Intact Proteins Using the PNGase Rc Immobilized-Enzyme Reactor</strong></a></h4><p>Katarína Molnárová, Petr Novák, Jana Nováková, and Petr Pompach*</p><p>ACS Omega 2026, 11, 17, 25724–25729</p><p><a target="_blank" rel="noopener noreferrer" href="https://doi.org/10.1021/acsomega.6c00577">https://doi.org/10.1021/acsomega.6c00577</a></p><h6>licensed under <a target="_blank" rel="noopener noreferrer" href="https://creativecommons.org/licenses/by/4.0/"><strong>CC-BY 4.0</strong></a></h6></blockquote><p><strong>Selected sections from the article follow.

The scheme of the system is shown on <a target="_blank" rel="noopener noreferrer" href="https://pubs.acs.org/doi/10.1021/acsomega.6c00577#fig1">Figure 1</a>. Samples of 50 mM ammonium bicarbonate buffer (pH 8.2) and 40 mM TCEP were placed in a sample tray at 4 °C. Ten microliters of the protein sample at a concentration of 0.03 mg/mL (0.3 μg per injection) were added to 40 μL of 50 mM ammonium bicarbonate and then transferred to 50 μL of 40 mM TCEP, pH 2.3. The disulfide bond reduction was carried at 40 °C for 5 min. The automated sample handling system injected 100 μL of the reaction mixture into the sample loop and switched the injection valve. Online deglycosylation was performed at room temperature using a PNGase Rc IMER (2.1 × 20 mm, AffiPro, Czech Republic) at a flow rate of 50 μL/min, followed by protein desalting on an OPTI-TRAP (0.5 × 2 mm) trap column (Optimize Technologies Inc., Oregon City, Oregon, USA) heated to 55 °C for 10 min with 0.2% formic acid delivered by an <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/library?mainauthorItems=10&amp;search=1260+Infinity+III+isocratic+pump"><strong>Agilent 1260 Infinity III isocratic pump</strong></a><strong> </strong>(Agilent Technologies, Santa Clara, California, USA). By switching the trap valve, the protein was eluted by an acetonitrile gradient [(min)/% B] 0/10-9/10-16/70-16.5/90-17/90-18/10-23/10] delivered by the <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/library?mainauthorItems=10&amp;search=1290+Infinity+II+LC"><strong>Agilent 1290 Infinity II HPLC</strong></a> system (Agilent Technologies, Santa Clara, California, USA) at a flow rate of 20 μL/min.

Haptoglobin phenotype 2-1, used in this study, forms multimers consisting of β-chain and disulfide linked α1 and α2 chains. <a href="javascript:void(0);">(19)</a> The detection of glycosylated Hp β-chain requires reduction of the disulfide bonds by incubating the protein with a reducing reagent. TCEP is a common reducing reagent used for fast reduction of disulfide bonds at various pH levels. Forty degrees Celsius, the maximum temperature of the PAL tray, and 5 min of incubation were sufficient for complete reduction of Hp disulfide bonds. Individual signals corresponding to the glycosylated β-chain were observed in the <i>m</i>/<i>z</i> range of 35,800–37,400 (<a target="_blank" rel="noopener noreferrer" href="https://pubs.acs.org/doi/10.1021/acsomega.6c00577#fig2">Figure 2</a>a).

The other study by Jmeian et al., which focused on released <i>N</i>-glycans, implemented a PNGase F IMER with online LC–MS detection. <a href="javascript:void(0);">(13)</a> The authors show the effectiveness of the method by identifying many different glycans released from a single protein or from a complex plasma mixture. Our approach is not directly intended for released <i>N</i>-glycan analysis; instead, it demonstrates the ability to measure intact proteins after rapid online deglycosylation using PNGase Rc at low pH. Samples prepared immediately prior to mass spectrometry analysis using the automated sample-handling platform can reduce variability associated with autosampler residence time, as some proteins may undergo degradation or precipitation during storage in the autosampler.</p><p>Although all glycoproteins in this study were effectively deglycosylated, the method’s efficiency depends on the characteristics of the individual glycoprotein. Therefore, optimizing method parameters─including the isocratic flow rate, glycoprotein incubation time with TCEP, and/or the addition of denaturing reagent─may improve the overall efficiency of the deglycosylation process.</p><p>The PNGase Rc IMER stability over a series of injections was tested by using the trastuzumab antibody.

As shown in <a target="_blank" rel="noopener noreferrer" href="https://pubs.acs.org/doi/10.1021/acsomega.6c00577#fig5">Figure 5</a>, the results indicate that the column performance remained stable over the course of the 150 measurements, and no glycosylated form of the trastuzumab antibody heavy chain was detected. The activity of PNGase Rc in the presence of 5% acetonitrile and 5% propan-2-ol was evaluated using a bottom-up approach with human 2–1 haptoglobin, which was online-digested by a coimmobilized nepenthesin-2/pepsin IMER. In the absence of an organic solvent, the peptide IEKVVLHPNYSQVD remained fully deglycosylated throughout 30 injections.

The column showed high sensitivity toward Hp, which has multiple glycosylation sites with various glycan structures, confirming its suitability for the profiling of complex glycoproteins. Bevacizumab and trastuzumab exhibited similar glycosylation profiles, with core-fucosylated biantennary glycans being the most abundant. Online deglycosylation with the PNGase Rc column resulted in a complete removal of the glycans from the heavy chains of both antibodies, proving that the column can be used for the rapid online deglycosylation of intact therapeutic mAbs. Moreover, the column remained stable over 150 measurements without any loss of activity, even when it was maintained at laboratory temperature. The significantly reduced reaction time, together with full automation and the absence of manual handling steps, substantially improves analytical throughput compared to conventional off-line deglycosylation workflows. These findings highlight the potential of the PNGase Rc IMER in the development of glycoprotein-based biopharmaceuticals, where detailed structural characterization of the protein part is critical for quality control, monitoring batch-to-batch variability, and stability testing.</p></div>
