Details

The Hach Sodium Platinum Series Combination Electrode is a reliable electrode designed for general purpose sodium measurement in all kinds of sample. Its renewable, free flowing reference junction provides fast and accurate sodium measurements. Diluted electrolyte and contaminants are removed from the junction after each pump to ensure stable, reproducible reference potentials.

The electrode uses an improved sodium-selective glass membrane containing an inner filling solution with a constant sodium ion concentration and glycerol as an antifreeze agent. The glass is a LAS (lithium aluminosilicate) glass. Special doping agents in the glass improve selectivity for sodium ions. A potential develops across the membrane that is proportional to the sodium concentration in the standard or sample.

Mining Waste Cleanup Reveals Interesting Lake Dynamics

For the past decade or so, Dr. Bernard Laval , a civil engineer with the University of Northern BC in Canada, has been researching Quesnel Lake , a large, deep lake with unusual water dynamics. This allowed him an unusually high level of insight into much of what makes the lake tick—and when Mount Polley Mine (MPM) experienced a breach in 2014, causing materials to be deposited into Quesnel Lake, he already had a sense of what the lake's waters looked like. “Our work was inspired by a desire to improve holistic understanding of lake function to help with fisheries management by BC Ministry of Environment (BC MOE) and Fisheries and Ocean Canada (DFO),” explains Dr. Laval.

Narragansett Nature: Remote NERR is a leader in salt marsh stressor studies, crab studies and contributions to Rhode Island environmental policies

Unique among the 29 National Estuarine Research Reserves (NERRS), Narragansett Bay National Estuarine Research Reserve (NBNERR ) is made up of four islands: Prudence, Patience, Hope and Dyer. Protecting about 4,400 acres of land and water, NBNERR is a great place to see a variety of coastal habitats. There are upland maritime forests, coastal pine barrens, sandy beaches, cobble shorelines, salt marshes and open grasslands. NBNERR also has excellent hiking, fishing, clamming and bird watching. “If you want to see us, though, you’ll need to hop on a ferry,” says Bob Stankelis , NBNERR Reserve Manager. “Or you’ll have to take a boat. We’re not that easy to get to. But to be honest, that’s one of the big things residents here like about it: its remoteness.

Acid Rain Data Helping Scientists Tackle Water Quality Issues

Since the 1980s, scientists from the Vermont Department of Environmental Conservation (VT DEC) have been sampling water from acid-impaired ponds and lakes and tracking data related to acidity. The line of inquiry began in response to concerns about acid rain, but DEC scientists now find that the long-term monitoring is not only proving the efficacy of the Clean Air Act but also improving local water quality. Guarding the environment in Vermont Rebecca Harvey is a VT DEC scientist, and monitoring the state's waterways for acidity and other problems falls in part to her. Dr. Harvey corresponded with EM about this work.
