During rain events, biocides and plant protection products are transported from agricultural fields but also from urban sources to surface waters. Originally designed to be biologically active, these compounds may harm organisms in aquatic ecosystems

Biocides and pesticides are designed to control the occurrence of unwanted organisms. From their point of application, these substances can be mobilized and transported to surface waters posing a threat to the aquatic environment. Historically, agric

The kinetics of chlorine dioxide consumption by a wide range of inorganic and organic compounds, including a comprehensive series of phenols, have been determined using conventional batch-type and stopped-flow methods. In all cases, the rate law was

Ammonia oxidation by ozone proceeds more rapidly in the presence of bromide ion than in its absence. Unlike the direct ozonation of ammonia, the bromide-catalyzed process is little affected by changes in pH. A reaction scheme is proposed in which bro

The concentration of hydrogen peroxide (H2O2) in distilled water, drinking water and in different types of surface and rain waters can be easily determined by a photometric method in which N,N-diethyl-p-phenylenediamine (DPD) is oxidized by a peroxid

In order to transfer experience from one waterwork to another, it is helpful to know (i) the spontaneous ozone requirement, (ii) the lifetime of the ozone, and (iii) the oxidation efficiency of the secondary oxidants derived from decomposed ozone (OH

The oxidation kinetics of butyl chloride, nitrobenzene, anisole, and methylmercury in the presence of hydroxyl radical (OH) scavengers were used to determine the rate and quantum efficiency for production of OH from irradiated nitrate ions in water.

Chlorination of waters from mesotrophic Lake Zurich and eutrophic Greifensee formed about 0.4 and 2 μg 1−1 of trichloronitromethane (TCNM) respectively. Pre-ozonation increased these values to about 2 and 6 μg 1−1. The formation of chloroform w
