Volatile Organic Compounds (VOCs) as Environmental Pollutants: Occurrence and Mitigation Using Nanomaterials

International Journal of Environmental Research and Public Health, 2021
Volatile organic compounds (VOCs) comprise various organic chemicals which are released as gases from different liquids or solids. The nature and impact of the health effects are dependent on the VOCs concentrations and, also, on the exposure time.

Formation of reactive nitrogen species promoted by iron ions through the photochemistry of a neonicotinoid insecticide [PDF]

Atmospheric Chemistry and Physics
Nitrous acid (HONO) and nitrogen oxides (NOx=NO+NO2) are important atmospheric pollutants and key intermediates in the global nitrogen cycle, but their sources and formation mechanisms are still poorly understood.

Volatile Compounds of the Cyanophyceae – A Review

Water Science and Technology, 1983
A relationship between blue-green algae and off-flavours in water was reported as early as 1883. Continuing research has shown that two metabolites, geosmin and methylisoborneol are major contributors to unpalatable flavours in water and aquatic organisms.

Volatile compounds present in traditional meat products (charqui and longaniza sausage) in Chile

Brazilian Archives of Biology and Technology, 2012
The aim of this work was to identify and quantify the volatile compounds in five different commercial brands of charqui and longaniza sausages. Volatile compounds were extracted from some samples headspace using solid phase microextraction (SPME).
