Are chemical contaminants in the foods we eat, in the products we put into and on our bodies and in our lakes and rivers causing birth defects in humans?

Louis J. Gillette Jr.

Louis J. Guillette Jr., an internationally recognized reproductive biologist who has spent 25 years

studying sexually stunted alligators and other wildlife from polluted waters in Florida and around the world, says a growing body of research shows those chemicals – including trace amounts often found in lakes and rivers — do cause birth defects, both in animals and humans.

On Sept. 14, Guillette, a professor of obstetrics and gynecology at the Medical University of South Carolina, will deliver the third in a series of lectures sponsored by the Freshwater Society and the University of Minnesota’s College of Biological Sciences.

Guillette’s lecture, aimed at a general audience, will be titled: Contaminants, Water and Our Health: New Lessons from Wildlife.

A panel of Minnesota experts on environmental contaminants will appear with Guillette.

The lecture will be at 7 p.m. in the theater of the St. Paul Student Center on the University of Minnesota’s campus.  The lecture, funded by an endowment honoring former university president Malcolm Moos, is free and open to the public. But seating is limited, and registration is required. To register, click here.

Asian carp, those giant, jumping fish that have moved up the Mississippi River in recent years and are threatening to enter the Great Lakes at Chicago, get all the media attention these days. But common carp, the kind that first were introduced into Minnesota lakes in about 1900, do immense damage to lakes and native plants, fish and wildlife every year.

The Rice Creek Watershed District will host a public workshop on common carp, and their effect on wildlife and water quality from 9 to 11:30 a.m. Saturday, Sept. 18, in the auditorium of Mounds View

Zebra mussels – an invasive species that poses serious ecological and economic threats to Minnesota’s lakes and streams – have now spread to Lake Minnetonka, the Department of Natural Resources announced on July 28.

For years, the DNR has worked with lake residents and users to prevent the  introduction of zebra mussels to Lake Minnetonka.

Heavy infestations of zebra mussels can kill native mussels, impact fish populations, interfere with recreation, and increase costs for industry, including power and water supply facilities. Native to Eastern Europe and Western Russia, zebra mussels were first discovered in Minnesota in 1989 in the Duluth harbor.
