Numerous acids and bases influence indoor air quality. The most abundant of these species are CO2 (acidic) and NH3 (basic), both emitted by building occupants. Other prominent inorganic acids are HNO3 , HONO, SO2 , H2 SO4 , HCl, and HOCl.

Potentials to differentiate milk composition by different feeding strategies [PDF]
To investigate the effect of the dietary intake of the cow on milk composition, bulk-tank milk was collected on 5 occasions from conventional (n = 15) and organic (n = 10) farms in Denmark and on 4 occasions from low-input nonorganic farms in the United ...

Exploring RNA modifications in infectious non-coding circular RNAs
Viroids, small circular non-coding RNAs, act as infectious pathogens in higher plants, demonstrating high stability despite consisting solely of naked RNA.

Real-time measurements of gas-phase organic acids using SF6− chemical ionization mass spectrometry [PDF]
The sources and atmospheric chemistry of gas-phase organic acids are currently poorly understood, due in part to the limited range of measurement techniques available.

Atomic Structures of Molecules Based on Additivity of Atomic and/or Ionic Radii [PDF]
The authors have shown in recent years that interatomic and interionic distances are sums of the radii of the adjacent atoms and/or ions. Many examples will be provided and it will be shown how the experimental bond lengths agree with the radii sums. The

Weak Acids Enhance Halogen Activation on Atmospheric Water’s Surfaces [PDF]
We report that rates of I_2(g) emissions, measured via cavity ring-down spectroscopy, during the heterogeneous ozonation of interfacial iodide: I^–(surface, s) + O_3(g) + H+(s) →→ I_2(g), are enhanced several-fold, whereas those of IO·(g) are unaffected,

Plant Organic Acids as Natural Inhibitors of Foodborne Pathogens
Background: Foodborne infections affect approximately 600 million people annually. Simultaneously, many plants contain substances like organic acids, which have antimicrobial activity. The aim of this study was to examine the effects of 21 organic acids,
