Certain biogenic secondary organic aerosols (SOA) become absorbent and fluorescent
when exposed to reduced nitrogen compounds such as ammonia, amines, and their salts …

The light-absorbing fraction of organic molecules in ambient aerosols, known as “brown
carbon,” is an important yet poorly characterized component. Despite the fact that brown …

Both rhizosphere bacteria and humic substances (HSs) can promote plant growth when
applied individually and even greater effects of their combination have been demonstrated …

Purpose Over the last decades, commercial humic products (HPs) from various resources
found multiple applications in agriculture and environmental technologies. The key factor …

The composition, structure, and biological activity of humic-like substances (HLS)
synthesized in the process of lignosulfonate conversion for the production of the humic …

The absolute luminescence quantum yield Q as a function of excitation wavelength λ ex in a
wide spectral range 270–470 nm was measured for the first time for the group of carbon …

Along the shoreline of the White Sea, due to the post-glacial uplift of the coast, some water
bodies with stable stratification have been formed. They have been classified as meromictic …

Along with traditional optical indices, calculated from absorption and fluorescence spectra to
describe chromophoric dissolved organic matter (CDOM) naturally occurring in water, the …

Systematic spectroscopic investigations revealed bimetallic complexation of faecal pigments
(FP) in water through their multiple binding sites. FP-Zn (II)/Gd (III) complexes showed …
