Avian, salamander, and forest floor mercury concentrations increase with elevation in a terrestrial ecosystem

High‐elevation ecosystems of the northeastern United States are vulnerable to deposition and environmental accumulation of atmospheric pollutants, yet little work has been done to assess mercury (Hg) concentrations in organisms occupying montane ecosystems. The authors present data on Hg concentrations in ground‐foraging insectivorous songbirds, a terrestrial salamander, and forest floor ...

Chemical Oxygen Demand Index (COD) System

The HydroTest COD System HTCOD is designed for the determination of chemical oxygen demand index (COD) using the small-scale sealed-tube method. The industry standard dichromate method can be considered as an estimate of theoretical oxygen demand. With a wide measuring range from 0 – 15,000 mg/L O2, the HTCOD is ideal for waste water testing, offering a small handheld photometer with two ...
