Photocatalytic coatings incorporating nano-TiO2 have emerged as effective solutions for air purification, utilizing solar radiation to degrade airborne pollutants. However, the long-term stability of such coatings, particularly those based on organic binders, remains a concern due their susceptibility photocatalytic-driven degradation.

Air quality on swine farms has long been a concern for both human and health as it previously linked with respiratory issues; the main cause being inhalation of small airborne particulate matter (PM) < 10 μm in diameter. Negative ionizing systems have successfully used to improve air residential- commercial buildings well agricultural settings. However, less is known about efficacy negative farrowing environments. Thus, objective this study was use environment evaluate effects ionization system 1) quantity gaseous matter, 2) production parameters. Six rooms containing 60 sows each were installed 30 per room. Three out six randomly allocated between active (L-ON) or inactive (L-OFF) rounds (N = 4). For round, measurements PM 2.5 , Ammonia (NH 3 ), hydrogen sulfide gas (H 2 S), temperature, humidity collected twice week, morning afternoon at two heights, pig level (61 cm) (152 cm). Pig performance metrics (parity, number piglets born, live piglet mortality, fostered piglets, weaned pigs) end batch. Comparisons L-ON L-OFF treatments conducted by averaging room day specific all days when rotating shared contrasting treatments. Each room-specific treatment then compared other using linear regression model. No statistically significant differences found nor level. numerical reductions cumulative increase 60% rooms. One five showed slower buildup NH concentrations ( P 0.01) had significantly H S 0.01). effect In conclusion, indications improved study, but given complexity these types assessments, further work needed conclude systems.
