Photoreductive Mechanism of CCl4 Degradation on TiO2 Particles and Effects of Electron Donors.
Wonyong Choi,Michael R. Hoffmann +1 more
TL;DR: The photoreductive degradation of CCl_4 in TiO_2 particulate suspensions in the presence of a variety of organic electron donors (alcohols, carboxylic acids, and benzene derivatives) has been examined and it is demonstrated that CCl-4 can be fully degraded under both oxic and anoxic conditions.
Journal ArticleDOI
Kinetics and mechanism of the sonolytic degradation of chlorinated hydrocarbons: Frequency effects
TL;DR: In this article, the kinetics of the sonolytic degradation of aqueous solutions of carbon tetrachloride and hexachloroethane (C_2Cl_6) were investigated at six different frequencies over the range from 20 to 1078 kHz.
Journal ArticleDOI
Kinetics and Mechanism of Pentachlorophenol Degradation by Sonication, Ozonation, and Sonolytic Ozonation
TL;DR: In this article, the decomposition of pentachlorophenol (PCP) by sonication was investigated at two frequencies (20 and 500 kHz) and two concentrations (20, 60 μM) to gain insight into the kinetics and mechanisms occurring at different frequencies.
Journal ArticleDOI
Chemical composition of fogwater collected along the California coast.
TL;DR: Substantial influences from continental and anthropogenic sources were observed even at the remote more » coastal sites, and emissions of NH/sub 3/ and calcareous dust are slight along the coast, acid-neutralizing capacities in coastal air are insufficient to neutralize even small acid inputs.
Journal ArticleDOI
Measuring Terrestrial Area of Habitat (AOH) and Its Utility for the IUCN Red List.
Thomas M. Brooks,Thomas M. Brooks,Thomas M. Brooks,Stuart L. Pimm,H. Resit Akçakaya,Graeme M. Buchanan,Stuart H. M. Butchart,Stuart H. M. Butchart,Wendy Foden,Wendy Foden,Wendy Foden,Craig Hilton-Taylor,Michael R. Hoffmann,Clinton N. Jenkins,Lucas Joppa,Binbin V. Li,Vivek Menon,Natalia Ocampo-Peñuela,Carlo Rondinini +18 more
TL;DR: It is recommended that IUCN Red List assessments document AOH wherever practical, because it can guide conservation, for example, through targeting areas for field surveys, assessing proportions of species' habitat within protected areas, and monitoring habitat loss and fragmentation.
