Air pollutants seriously interfere with the maintenance of unipolar ionized atmospheres required in experimenting with the biological effects of gaseous ions. The construction and operation of an air purification unit designed to reduce air pollution to tolerable levels are described; it has functioned satisfactorily in conducting experiments with plants and animals.

Water and air pollutants have huge impacts on the entire living system. In addition, the newly emerging nanopollutants, increasing global warming, and consequent climate changes are posing major threats to the freshwater or fresh air availability. This has made it urgent to invent an appropriate water/air treatment technology that removes nanopollutants and also desalinates water to a significa...

  Background and Aims:Nosocomial infections cause considerable morbidity and mortality and pose high financial burden on healthcare systems. Although surface contact, surgical incisions, wounds and catheters are responsible for a high percentage of nosocomial infections, bacterial and fungal air contaminations in hospitals have an important role in development of hospital infections. The p...

Mesoporous ferrihydrite nanoparticles with incorporated Mn (MMnFh) were prepared for the first time, and MMnFh exhibits excellent performance in removing organic contaminants (CH(3)CHO and toluene) in air. The interesting physico-chemical properties and remarkable activity of MMnFh give great commercial potential in air purification application in diverse sectors.

The indoor air quality in public transport systems is a major concern South Korea. Within this context, we investigated the effect of purification on intercity buses, one most popular options Air purifiers were custom designed and equipped with high-efficiency particulate (HEPA) filters to remove matter ultraviolet light-emitting diodes (UV-LEDs) airborne bacteria. To investigate effectiveness ...
