“…Closer to our own institution, the state of Minnesota has been at the forefront of state-based regulation of mercury via its own ongoing reduction plan, the Mercury Total Maximum Daily Load, initiated in 2007 . In the laboratory setting, replacement of mercury thermometers was the primary target given their ubiquity and heavy use. − Mercury-based bubblers for Schlenk lines are a common laboratory application of mercury that has lingered as no easily implemented, universal, and comparable replacement has arisen.
