Summary: A new type of disinfectant containing zinc phthalocyanine (ZnPc) was synthesized and showed higher antimicrobial effect against bacteria compared to traditional quaternary ammonium compounds (QACs). The disinfectant exhibited enhanced bactericidal toxicity at nanomolar concentrations when combined with specific light wavelengths. Furthermore, it was safe for mammalian cells and environmentally friendly due to its degradation under sunlight illumination.

Summary: This study provides a quantitative review and systematic analysis on the effectiveness of quaternary ammonium compounds (QACs) in disinfecting nonfungal plant pathogens. The findings suggest that QACs are moderately effective against nonfungal pathogens, with their efficacy influenced by factors such as dose, contact time, organism type, genus, target, and QAC product generation.

Summary: Quaternary ammonium compounds (QACs) in European indoor dust were identified, characterized, and semi-quantified using ion-mobility high-resolution mass spectrometry. Targeted QACs (21) and suspect QACs (17) were detected with high detection frequencies. The concentrations of individual QACs were estimated and daily intakes for adults and toddlers were calculated. This study provides important insights into the potential human exposure to QACs.
