Abstract
Benzalkonium chlorides (BACs) are commonly used disinfectants in a variety of consumer and food-processing settings, and the COVID-19 pandemic has led to increased usage of BACs. The prevalence of BACs raises the concern that BAC exposure could disrupt the gastrointestinal microbiota, thus interfering with the beneficial functions of the microbes. We hypothesize that BAC exposure can alter the gut microbiome diversity and composition, which will disrupt bile acid homeostasis along the gut-liver axis. In this study, male and female mice were exposed orally to d 7 -C12- and d 7 -C16-BACs at 120 µg/g/day for one week. UPLC-MS/MS analysis of liver, blood, and fecal samples of BAC-treated mice demonstrated the absorption and metabolism of BACs. Both parent BACs and their metabolites were detected in all exposed samples. Additionally, 16S rRNA sequencing was carried out on the bacterial DNA isolated from the cecum intestinal content. For female mice, and to a lesser extent in males, we found that treatment with either d 7 -C12- or d 7 -C16-BAC led to decreased alpha diversity and differential composition of gut bacteria with notably decreased actinobacteria phylum. Lastly, through a targeted bile acid quantitation analysis, we observed decreases in secondary bile acids in BAC-treated mice, which was more pronounced in the female mice. This finding is supported by decreases in bacteria known to metabolize primary bile acids into secondary bile acids, such as the families of Ruminococcaceae and Lachnospiraceae. Together, these data signify the potential impact of BACs on human health through disturbance of the gut microbiome and gut-liver interactions.

Abstract
The use of disinfectants, particularly those containing quaternary ammonium compounds (QUACs), has dramatically escalated globally since the coronavirus disease 2019 pandemic. We report a case that highlights the risks associated with ingesting low-concentration QUAC solutions and emphasize the importance of effective management in resolving severe lesions without sequelae. A 17-month-old boy experienced severe respiratory failure after ingesting a disinfectant containing benzalkonium chloride (BAC). The child was initially treated at a local emergency department and was subsequently transferred to a pediatric poison center. Upon evaluation, the child was found to have grade III-A corrosive esophageal lesions and chemical pneumonitis. Several complications, including massive pneumothorax and candidemia, occurred during the clinical course of the disease. However, with timely medical intervention and appropriate supportive care, the patient completely recovered without any long-term sequelae. The properties of BAC and the comprehensive management approach may have been responsible for the patient's full recovery, despite the potentially life-threatening effects of ingesting disinfectants.

Toxicologic pathological mechanism of acute lung injury induced by oral administration of benzalkonium chloride in mice. Toxicol Res 2023; 39:409-418.

Abstract
Benzalkonium chloride (BAC) intoxication causes fatal lung injuries, such as acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). However, the pathogenesis of ALI/ARDS induced by BAC ingestion is poorly understood. This study aimed to clarify the mechanism of lung toxicity after BAC ingestion in a mouse model. BAC was orally administered to C57BL/6 mice at doses of 100, 250, and 1250 mg/kg. After administration, BAC concentrations in the blood and lungs were evaluated via liquid chromatography with tandem mass spectrometry. Lung tissue injury was evaluated via histological and protein analyses. Blood and lung BAC concentration levels after oral administration increased in a dose-dependent manner, with the concentrations directly proportional to the dose administered. The severity of lung injury worsened over time after the oral administration of 1250 mg/kg BAC. An increase in the terminal transferase dUTP nick end labeling-positive cells and cleaved caspase-3 levels was observed in the lungs after 1250 mg/kg BAC administration. In addition, increased cleaved caspase-9 levels and mitochondrial cytochrome c release into the cytosol were observed. These results suggest that lung tissue injury with excessive apoptosis contributes to BAC-induced ALI development and exacerbation. Our findings provide useful information for developing an effective treatment for ALI/ARDS induced by BAC ingestion.

Quaternary Ammonium Compounds: A Chemical Class of Emerging Concern. ENVIRONMENTAL SCIENCE & TECHNOLOGY 2023; 57:7645-7665.

Abstract
Quaternary ammonium compounds (QACs), a large class of chemicals that includes high production volume substances, have been used for decades as antimicrobials, preservatives, and antistatic agents and for other functions in cleaning, disinfecting, personal care products, and durable consumer goods. QAC use has accelerated in response to the COVID-19 pandemic and the banning of 19 antimicrobials from several personal care products by the US Food and Drug Administration in 2016. Studies conducted before and after the onset of the pandemic indicate increased human exposure to QACs. Environmental releases of these chemicals have also increased. Emerging information on adverse environmental and human health impacts of QACs is motivating a reconsideration of the risks and benefits across the life cycle of their production, use, and disposal. This work presents a critical review of the literature and scientific perspective developed by a multidisciplinary, multi-institutional team of authors from academia, governmental, and nonprofit organizations. The review evaluates currently available information on the ecological and human health profile of QACs and identifies multiple areas of potential concern. Adverse ecological effects include acute and chronic toxicity to susceptible aquatic organisms, with concentrations of some QACs approaching levels of concern. Suspected or known adverse health outcomes include dermal and respiratory effects, developmental and reproductive toxicity, disruption of metabolic function such as lipid homeostasis, and impairment of mitochondrial function. QACs' role in antimicrobial resistance has also been demonstrated. In the US regulatory system, how a QAC is managed depends on how it is used, for example in pesticides or personal care products. This can result in the same QACs receiving different degrees of scrutiny depending on the use and the agency regulating it. Further, the US Environmental Protection Agency's current method of grouping QACs based on structure, first proposed in 1988, is insufficient to address the wide range of QAC chemistries, potential toxicities, and exposure scenarios. Consequently, exposures to common mixtures of QACs and from multiple sources remain largely unassessed. Some restrictions on the use of QACs have been implemented in the US and elsewhere, primarily focused on personal care products. Assessing the risks posed by QACs is hampered by their vast structural diversity and a lack of quantitative data on exposure and toxicity for the majority of these compounds. This review identifies important data gaps and provides research and policy recommendations for preserving the utility of QAC chemistries while also seeking to limit adverse environmental and human health effects.

Use of QuEChERS as a manual and automated high-throughput protocol for investigating environmental matrices. CHEMOSPHERE 2022; 308:136313.

Abstract
Environmental pollution has strong links to adverse human health outcomes with risks of pollution through production, use, ineffective wastewater (WW) remediation, and/or leachate from landfill. 'Fit-for-purpose' monitoring approaches are critical for better pollution control and mitigation of harm, with current sample preparation methods for complex environmental matrices typically time-consuming and labour intensive, unsuitable for high-throughput screening. This study has shown that a modified 'Quick Easy Cheap Effective Rugged and Safe' (QuEChERS) sample preparation is a viable alternative for selected environmental matrices required for pollution monitoring (e.g. WW effluent, treated sludge cake and homogenised biota tissue). As a manual approach, reduced extraction times (hours to ∼20 min/sample) with largely reproducible (albeit lower) recoveries of a range of pharmaceuticals and biocidal surfactants have been reported. Its application has shown clear differentiation of matrices via chemometrics, and the measurement of pollutants of interest to the UK WW industry at concentrations significantly above suggested instrument detection limits (IDL) for sludge, indicating insufficient removal and/or bioaccumulation during WW treatment. Furthermore, new pollutant candidates of emerging concern were identified - these included detergents, polymers and pharmaceuticals, with quaternary ammonium compound (QAC) biocides observed at 2.3-70.4 mg/kg, and above levels associated with priority substances for environmental quality regulation (EQSD). Finally, the QuEChERS protocol was adapted to function as a fully automated workflow, further reducing the resource to complete both the preparation and analysis to <40 min. This operated with improved recovery for soil and biota (>62%), and when applied to a largely un-investigated clay matrix, acceptable recovery (88.0-131.1%) and precision (≤10.3% RSD) for the tested pharmaceuticals and biocides was maintained. Therefore, this preliminary study has shown the successful application of a high-throughput QuEChERS protocol across a range of environmental solids for potential deployment in a regulated laboratory.

Abstract
Lysoform® in the formulation of professional detergent is widely used in several fields, whereas its suicidal ingestion is an unusual occurrence. Therefore, the biological signs of this fatal poisoning remain unclear and elusive, similarly to the histological lesions induced by its main constituent, which is benzalkonium chloride (BZK). Furthermore, since all the deaths that has been reported in the literature occurred immediately, microscopic pictures of BZK lethal toxicity in subjects with prolonged survival have never been reported to date. Specifically, this brief communication reports the unique case of a woman who ingested professional Lysoform® to commit suicide, for which she died two weeks later. The autopsy examination showed either local or systemic signs of caustic ingestion; moreover, the histological analysis showed clear cellular damage of lungs, heart, and kidneys. In our case, toxicological investigations were not authorized as they were no longer considered significant. In this framework, the histological examination has therefore assumed a fundamental role in investigating and demonstrating the lethal effects caused by the systemic dissemination of BZK, which would otherwise no longer be investigable. Therefore, in cases of substance intoxication with prolonged survival where forensic toxicological investigations may be no longer possible or feasible, the histological examination may be the only resource to successfully observe and demonstrate its lethal effects.

Abstract
RATIONALE N,N-Dimethyldodecylamine is produced from lauryl alcohol and dimethylamine. C12-C16 alkyldimethylamines are used as intermediates for the manufacture of amineoxides and quaternary amino compounds. In the present study a gas chromatography-mass spectrometry (GC/MS) method for the determination of C12-C16 alkyldimethylamines in blood was developed and validated. The reason for this study was the detection of the above compounds in the postmortem blood sample of a fatal suicide case. METHODS Analysis of amines was performed using a gas chromatograph (Agilent Technologies 7890A) with an MS 5975C inrXL, EI/CI MSD with triple-axis detector in selected ion monitoring mode, after liquid-liquid extraction. Four different organic solvents (butyl acetate, ethyl acetate, n-hexane and n-heptane) were used for the optimization of the extraction procedure, resulting in ethyl acetate being the solvent of choice for the extraction procedure. A QuEChERS step was applied (20 mg of MgSO4 , 5 mg of NaCl) to 1 mL of blood and pH was adjusted at 12 (K2 CO3 buffer solution). After the addition of the extraction solvent, samples were vortexed, centrifuged and directly injected into the GC/MS system. RESULTS In validation, the method was found to be selective and sensitive (limit of detection from 0.3 to 0.5 ng/mL, limit of quantitation from 10.0 to 20.0 ng/mL), whilst validation included recovery, stability, accuracy and precision (relative standard deviation). Validation results were found satisfactory: intra- and interday precision ranged from 0.4% to 2% and from 0.6% to 1.9% respectively, while intra- and interday accuracy ranged from 87% to 109% and from 86% to112.8%. C12-C16 alkyldimethylamines were detected in blood samples at a concentration of 8.39 μg/mL (C12), 3.01 μg/mL (C14) and 0.42 μg/mL (C16). CONCLUSIONS A rapid, sensitive and reliable method was developed for the determination of C12-C16 alkyldimethylamines in postmortem blood, after optimization of the sample preparation procedure, and finally successfully applied to a real postmortem blood sample from a fatal case involving these compounds.

Abstract
Benzalkonium chloride is widely used in disinfectants. Several toxicological and fatal cases have been reported; however, little is known about its kinetics and distribution. We investigated the kinetic characteristics and distribution of benzalkonium cation (BZK) based on the length of the alkyl chains C12, C14, and C16. Rats were treated intravenously with BZK solution (dose, 13.9 mg/kg) containing equal amounts of the three homologues. Kinetic parameters in the blood were assessed, and BZK distribution in the blood and tissues was examined both in rapid intravenous (IV) and drip intravenous (DIV) administrations. BZK concentrations were analysed by liquid chromatography-tandem mass spectrometry (LC-MS/MS). BZK with longer alkyl chains showed lower elimination tendencies and remained in the blood for a longer duration. Concentrations of BZK were higher in the heart, lung, spleen, and kidney than those in the blood, and lower in the brain and fat. In both the IV and DIV groups, the lung, liver, spleen, and fat samples showed higher concentrations of the longer alkyl chains (BZK-C12 < -C14 < -C16), and the opposite trend was observed in the kidney (BZK-C16 < -C14 < -C12). Only the heart and muscle samples displayed the homologues in ratios comparable to the original administered solutions. Differences between IV and DIV groups could be identified by comparing concentrations of BZK homologues in the heart, lung, spleen, and kidney samples. We found that the kinetics and distribution of BZK were influenced by the alkyl chain length, and analysing each BZK homologues in blood and tissue samples may provide useful information.

Abstract
Quaternary ammonium compounds (QACs) are broad-spectrum disinfectants used in a range of everyday materials. Their high usage rates, limited regulation and reporting has meant their environmental release is largely uncontrolled and impact unknown. With links to antimicrobial resistance (AMR) and adsorption to wastewater solids (that are recycled), there is a need for more controlled disposal measures and monitoring. These environmental matrices are highly complex requiring methods that are often laborious and costly to undertake. Using a robust quantitative reversed-phase LC-MS/MS method, we have shown that an 'off the shelf' QuEChERS product can reliably extract (<10% RSD) aromatic and aliphatic QACs anticipated within municipal, industrial and agricultural waste from water and soil, with reduced matrix effects of 95.7-104.4% for recoveries of up to 53% from soil when combined with extract dilution. Therefore, unlike current literature, this work has shown that, with minimal development, the QuEChERS product can provide a rapid, effective and low cost preparation for quantifying QAC pollution and monitoring AMR.

Abstract
In recent years, nanocellulose-based antimicrobial materials have attracted a great deal of attention due to their unique and potentially useful features. In this review, several representative types of nanocellulose and modification methods for antimicrobial applications are mainly focused on. Recent literature related with the preparation and applications of nanocellulose-based antimicrobial materials is reviewed. The fabrication of nanocellulose-based antimicrobial materials for wound dressings, drug carriers, and packaging materials is the focus of the research. The most important additives employed in the preparation of nanocellulose-based antimicrobial materials are presented, such as antibiotics, metal, and metal oxide nanoparticles, as well as chitosan. These nanocellulose-based antimicrobial materials can benefit many applications including wound dressings, drug carriers, and packaging materials. Finally, the challenges of industrial production and potentials for development of nanocellulose-based antimicrobial materials are discussed.
