Journal ArticleDOI
Sensing the fugacity of hydrophobic organic chemicals in aqueous systems
TL;DR: In this article, the fugacity of hydrophobic chemicals in aqueous systems was measured by measuring their concentrations in an equilibrated air headspace, which can provide valuable information about the nature and extent of interactions between the chemicals and dissolved and particulate phases present in the water.
Journal ArticleDOI
Environmental persistence of chemicals.
Donald Mackay,Eva Webster +1 more
TL;DR: It is concluded that the preferred strategy is to use Level II, III, and IV models and that the use of only degradation kinetics or media-specific half-lives can be misleading and uneconomical.
Journal ArticleDOI
Dependence of intake fraction on release location in a multi-media framework: A case study of four contaminants in North America
Matthew MacLeod,Deborah H. Bennett,Merike Perem,Randy L. Maddalena,Thomas E. McKone,Thomas E. McKone,Donald Mackay +6 more
TL;DR: In this article, the authors explored the relative importance of these variables using the regionally segmented BETR North America contaminant fate model and data for food production patterns and population density for North America.
Journal ArticleDOI
Relationship of hydrocarbon solubility to toxicity in algae and cellular membrane effects
TL;DR: In this paper, it was found that the molar concentration required to cause a 50 percent reduction in photosynthesis could be predicted from a knowledge of its solubility alone, and a regression coefficient of 0.97 was obtained on a log plot.
Journal ArticleDOI
Mass balance modelling of contaminants in river basins: A flexible matrix approach
TL;DR: By considering the spatially explicit nature of emission sources and the changes in concentration which occur with transport in the channel system, the approach offers significant advantages over simple one-segment simulations while being more readily applicable than more sophisticated, highly segmented, GIS-based models.
