Blood pressure is measured in millimeters of mercury (mm Hg). To determine whether someone has high blood pressure, known medically as hypertension, doctors classify blood pressure readings into ...

They then paired their data with nitrogen and mercury stable isotopes to identify the dietary source of methylmercury and the chemical reaction pathway. The isotopic composition of the Hg ...

The Arctic summer mercury (Hg) rebound has been debated for decades. This study uses a process-based model to show sea ice melt drives Hg emissions and increases Hg deposition in Arctic tundra ...
