TL;DR: A generalized framework for decision analysis is proposed to highlight the fundamental ingredients for more structured and tractable environmental decision making.

TL;DR: In this article, the authors describe a complex and confusing process characterized by trade-offs between socio-political, environmental, and economic impacts in decision-making in environmental projects, where cost-benefit analyses are often used, in concert with comparative risk assessment, to choose between competing project alternatives.

TL;DR: The key result is that the risks from mixed sources are driven predominantly by the proportion of the contamination source with the greatest ability to cause human infection (potency), not necessarily the greatest source(s) of FIB.

TL;DR: The U.S. Environmental Protection Agency recommends two statistical methods to States and Tribes for developing nutrient criteria as discussed by the authors, one establishes a criterion as the 75th percentile of a reference-population frequency distribution, the other uses the 25th percentiles of a general population distribution; the Environmental Protection Association suggests either method results in similar criteria, and the Montana Department of Environmental Quality (MT DEQ) assembled data from STORET and other sources to create a nutrient general population.

TL;DR: In this article , various modifications have been made to the structural and chemical properties of the photocatalysts, such as incorporating metal oxides and noble metals with varied morphologies into titania to fabricate ternary heterojunctions.
