Water Management “Tabat System” in Carbon Dioxide Mitigation and Vulnerability to Fire On Peatland

Moderate drop in water table increases peatland vulnerability to post-fire regime shift

Northern and tropical peatlands represent a globally significant carbon reserve accumulated over thousands of years of waterlogged conditions. It is unclear whether moderate drying predicted for northern peatlands will stimulate burning and carbon losses as has occurred in their smaller tropical counterparts where the carbon legacy has been destabilized due to severe drainage and deep peat fire...

Vulnerability of the peatland carbon sink to sea-level rise

Freshwater peatlands are carbon accumulating ecosystems where primary production exceeds organic matter decomposition rates in the soil, and therefore perform an important sink function in global carbon cycling. Typical peatland plant and microbial communities are adapted to the waterlogged, often acidic and low nutrient conditions that characterise them. Peatlands in coastal locations receive ...

End-tidal Carbon Dioxide Measurements in Unintentional Non-Fire-Related Carbon Monoxide Poisoning

Background: Poisoning with carbon monoxide occurs occasionally worldwide, and the gold diagnostic standard is to measure carboxyhemoglobin level in the blood. This study investigated the correlation between carboxyhemoglobin and the end-tidal carbon dioxide levels in 50 patients with carbon monoxide poisoning. Methods: We recruited 50 volunteer patients who had been admitted to the Emergency S...

Global vulnerability of peatlands to fire and carbon loss

11 Peatland ecosystems accumulate thick organic soil layers because plant production exceeds decomposition throughout the entire organic soil column (Fig. 1). Peatlands cover only about 2–3% of the Earth’s land surface but store around 25% of the world’s soil carbon1. They are most abundant at northern high latitudes (Fig. 2a), where they cover roughly 4,000,000 km2 of land1 and store an estima...
