MTK and TMK both stand for Thio-Michler's ketone (Michler's thioketone) and react with certain metals, including gold, silver, mercury and palladium. This reagent can be used for residual chlorine studies. TMB is tetramethylbenzidine and changes color when it comes into contact with ethyl acetate (turns blue/green) or chlorine (turns yellow). DPD is used to determine chlorine concentration by the vividness of the color produced. Depending on the specific reagent model, it can measure free and total chlorine concentrations from 0.02 -10 mg/L. Manganese can interfere with DPD reagents, but not with TMK/MTK reagents.

After 10 Years, Great Lakes Monitoring Program Still Adapting
The public knows much more about Great Lakes coastal wetlands than it did ten years ago. In those ten years, the information gathered through the Great Lakes Coastal Wetlands Monitoring Program has led to and supported dozens of advances in Great Lakes science while helping nail down the shifting nature of ecosystem health for a vital part of the Great Lakes system. “I probably get one or two requests for information a week,” Don Uzarski, director of the program, told Environmental Monitor. The program’s most recent semi-annual report lists 40 scientific publications using the collected data. In addition, the data has been used in even more restoration projects, graduate theses and presentations.

Fisheries Management Drives Fish Populations Recovery
You might be surprised to hear good news about the world’s oceans. The dominant narrative for years has been that the oceans’ sea life populations are on the brink of collapse. But, according to research Ray Hilborn published in January in the Proceedings of the National Academy of Sciences, the ocean’s fisheries are bouncing back, provided that they’re well managed. “The bottom line is that if fisheries are managed they are sustainable,” Hilborn, a professor at the University of Washington’s school of aquatic and fisheries sciences, told Environmental Monitor. New evidence of recovery After two decades of recovering fish populations, many of the world’s fisheries are stable or recovering, Hilborn’s research shows.

Chloride Contamination Threatens Thousands of Northeast & Midwest Lakes
Thousands of lakes in the northeastern United States are at risk of chloride contamination. In a 17-state area from Minnesota to Missouri to Maine, elevated chloride levels in some of the region’s nearly 50,000 lakes are driven largely by landscape features that are cleared of snow and ice by road salt in the winter. “The biggest driver of increasing chloride concentrations in these lakes was road density and development. The more developed a watershed, the more likely you are to have roads and parking lots,” said Hilary Dugan, an assistant professor in the Center for Limnology at University of Wisconsin—Madison. Dugan is the lead author on a study examining the issue recently published in Environmental Science and Technology .
