Effects of cleaning spray use on eyes, airways, and ergonomic load
BMC Public Health, 2023 Background Cleaning workers are exposed to chemicals and high physical workload, commonly resulting in airway problems and pain. In this study the response in the upper airways and the physical workload following airborne and ergonomic exposure of ...

Terrestrial or marine – indications towards the origin of ice-nucleating particles during melt season in the European Arctic up to 83.7° N [PDF]
Atmospheric Chemistry and Physics, 2021 Ice-nucleating particles (INPs) initiate the primary ice formation in clouds at temperatures above ca. −38 ∘C and have an impact on precipitation formation, cloud optical properties, and cloud persistence. Despite their roles in both weather and climate,

The Collection 6 MODIS aerosol products over land and ocean
, 2013 . The twin Moderate resolution Imaging Spectroradiometer (MODIS) sensors have been flying on Terra since 2000 and Aqua since 2002, creating an extensive data set of global Earth observations. Here, we introduce the Collection 6 (C6) algorithm to retrieve

Recognition of aerosol transmission of infectious agents: a commentary
BMC Infectious Diseases, 2019 Although short-range large-droplet transmission is possible for most respiratory infectious agents, deciding on whether the same agent is also airborne has a potentially huge impact on the types (and costs) of infection control interventions that are ...

Reactive nitrogen chemistry in aerosol water as a source of sulfate during haze events in China
Science Advances, 2016 Multiphase chemistry of NO2 and alkaline matter in aerosol water explains rapid sulfate formation and severe haze in China. Fine-particle pollution associated with winter haze threatens the health of more than 400 million people in the North China Plain.
