Singlet oxygen (1O2) is a reactive oxygen species produced in sunlit waters via energy
transfer from the triplet states of natural sensitizers. There has been an increasing interest in …

Absorption of sunlight by chromophoric dissolved natural organic matter (CDOM) is
environmentally significant because it controls photic zone depth and causes …

Chemical oxidation using peracetic acid (PAA) can be enhanced by activation with the
formation of reactive species such as organic radicals (R–O•) and HO•. Thermal activation is …

Advances in spectroscopic techniques have led to an increase in the use of optical
properties (absorbance and fluorescence) to assess dissolved organic matter (DOM) …

Dissolved organic matter (DOM) plays a vital role in biogeochemical processes and in
determining the responses of soil organic matter (SOM) to global change. Although the …

Dissolved organic matter (DOM) plays an important role in carbon cycling within inland
surface waters. Under sunlight irradiation, DOM undergoes complete photooxidation to …

The Arctic is a water-rich region, with freshwater systems covering about 16% of the northern
permafrost landscape. Permafrost thaw creates new freshwater ecosystems, while at the …

Dissolved black carbon (BC) released from biochar can be one of the more photoactive
components in the dissolved organic matter (DOM) pool. Dissolved BC was mainly …

Constructed wetlands (CWs) are frequently used for effective biological treatment of nitrogen-
rich wastewater with external carbon source addition; however, these approaches often …

Carbon in thawing permafrost soils may have global impacts on climate change; however,
the factors that control its processing and fate are poorly understood. The dominant fate of …
