environmental impacts

Good news for public health and water quality from Minnesota this week. By June of this year, state agencies and institutions will no longer be buying soaps and cleaning products containing the pesticide triclosan.

Governor Mark Dayton made the shift with an executive order signed Monday. The new policy — the first of its kind in the country — comes in response to a combination of strong science and public concern about the chemical's prevalence and harms.

Prairie bird populations are falling in many Midwestern states, from ring-necked pheasants to horned larks to sparrows. Scientists now say insecticides are a primary culprit.

Minnesota birds are hardest hit with 12 species in decline, followed by Wisconsin with 11, and Illinois, Michigan, Montana, Nebraska and New York with nine affected species each.

Minnesota lakes contains triclosan, say researchers. An anti-bacterial pesticide found in soap, toothpaste and many other products, triclosan is currently being (slowly) evaluated by both EPA and FDA. Meanwhile, many companies have already pulled it from their list of ingredients in response to concerns about the chemical's health and environmental harms.

University of Minnesota scientists analyzed sediment from eight lakes to understand trends in contaminant levels over time. They found that levels of triclosan and its byproducts have gone up steadily since the chemical entered the market in the 1970s.

Frogs exposed to commonly used pesticides in the lab had mortality rates between 40-100%, according to a new study in Germany. One fungicide, when applied at doses approved for use, caused frogs to die within an hour.

The new study provides strong support for earlier research pointing to pesticide exposure as a contributor to the global decline of amphibians, a disturbing trend that has puzzled researchers for years. Like canaries in a coal mine, frogs are often considered a "sentinel" species — and declines may be an early warning of broader harms.

“We’re facing the extinction of a species.” That’s what one Midwest-based large-scale commercial beekeeper told me last week at the annual gathering of the American Honey Producers Association (AHPA). And he meant it.

Bee losses have been dramatic, especially in recent years. And beekeepers are feeling the sting. According to many who manage hives, commercial beekeeping won’t pencil out in the future unless things change, and soon.
