The photochemical formation of hydrogen peroxide in tryptophan solutions and natural waters was monitored by a sensitive spectrophotometric assay. Peroxide was characterized by ion exchange properties and mobility via thin-layer chromatography. Tryptophan photodecomposed in sunlight or near ultraviolet light (λ > 283 nm) with the formation of uncharacterized, acidic photoproducts and hydrogen peroxide; other oxidants (i.e. organic peroxides) were not detected in tryptophan photolysis mixtures… 
Hydroxyl radical formation from bacteria-assisted Fenton chemistry at neutral pH under environmentally relevant conditions
Environmental context Reactions in natural waters such as lakes and streams are thought to be extremely slow in the absence of sunlight (e.g. at night). We demonstrate that in the presence of iron,
Evidence for photochemical generation of superoxide ion in humic waters
On irradiation with visible or near UV light the coloured substances in natural humic waters can undergo several reactions. They may be bleached and partially degraded1–3, perhaps by a cyclic
Photooxidant activity in natural waters
After exposure to sunlight or laboratory UV light, sterilized water samples (or their reconstituted concentrates) from California and Hawaii oxidized several common environmental contaminants,
Role of the photo-Fenton reaction in the production of hydroxyl radicals and photobleaching of colored dissolved organic matter in a coastal river of the southeastern United States
Abstract.Photochemical reactions involving colored dissolved organic matter (CDOM) in natural waters are important determinants of nutrient cycling, trace gas production and control of light
Photodegradation of Wastes and Pollutants in Aquatic Environment
Photocatalytic processes have considerable potential to contribute to the degradation of pollutants in the aquatic environment and in wastewater treatment. The sunlight irradiation of humic
On the photolysis of selected pesticides in the aquatic environment
The photodegradation (UV λ > 290nm) of the herbicides atrazine and diuron was examined in distilled water and artificial seawater containing humic acids. Major photodegradation products were
Apparent Quantum Efficiency Spectra for Superoxide Photoproduction and Its Formation of Hydrogen Peroxide in Natural Waters
Superoxide (O2−) is a key intermediate in the cycling of organic matter and trace metals in natural waters but production rates are difficult to determine due to low steady-state concentrations,


Singlet oxygen in natural waters
MANY studies have shown that singlet molecular oxygen can oxidise a variety of organic substances1–7. These studies have included biologically important compounds present in the aquatic environment
Free-Radical Oxidants in Natural Waters
The concentration of RO2� is large enough that, for some classes of reactive chemicals, oxidation can be an important process in natural waters.
Abstract— The production of singlet oxygen by thiazine dye photosensitization, as measured by the rate of photooxidation of tryptophan, was found to be very sensitive to changes of pH in the range
Characterization of a cell-lethal product from the photooxidation of tryptophan: hydrogen peroxide.
H2O2 has been shown to account for the biological activities of near-ultraviolet irradiation of saturated, oxygenated solutions of tryptophan in the absence of added sensitizer.
Experimental approaches to pesticide photodecomposition.
The past few years have witnessed a rapidly increasing interest in the decomposition (“metabolism”) of pesticides by micro-organisms, animals, and higher plants. Although the influence of non-living
Occurrence of Hydrogen Peroxide in Sea Water
TRACES of dissolved substances, of the order of 10−7 M or less, can or may have far-reaching effects on the type or growth rate of organisms in the sea1. We now wish to report the occurrence of a
