The end-Triassic mass extinction is one of the five most catastrophic in Phanerozoic Earth history. Here we report carbon isotope evidence of a pronounced productivity collapse at the boundary, coincident with a sudden extinction among marine plankton, from stratigraphic sections on the Queen Charlotte Islands, British Columbia, Canada.

The feasibility of recovering phosphates from municipal wastewater is assessed from literature, targeted interviews of water industry experts and process modeling. It is concluded that it is technically feasible to recover up to 75% of wastewater treatment plant (WwTP) inflow P, but today this is only attractive in WwTPs operating biological nutrient(More)
Methane is a highly potent greenhouse gas and contributes significantly to climate change. Recent studies have shown significant methane production in sewers. The studies conducted so far have relied on manual sampling followed by off-line laboratory-based chromatography analysis. These methods are labor-intensive when measuring methane emissions from a(More)
