CMU Studies Freshwater Contaminants, Michigan Gains Solar Jobs

For Feb. 10, 2017

1 – Contaminants of emerging concern are in everyday products from soap to pharmaceuticals.

But their environmental impact is largely unknown. A Central Michigan University biologist is studying how these contaminants in the water and sediment affect the ecosystems and life cycles of freshwater mussels.

Biologist Daelyn Woolnough is looking at freshwater mussels and largemouth bass, which act as hosts for mussel larvae.

Of the more than 40 freshwater mussel species in the Great Lakes, more than 70 percent are endangered or threatened. Their populations have been impacted by invasive species like the zebra mussel, and may be impacted by contaminants of emerging concern, which also include agricultural products.

Freshwater mussels filter water from the basins in which they reside, and they don’t move around like fish. So testing mussel tissue or contaminants will tell researchers what’s happening at the bottom of rivers.

The results may help inform management and conservation decisions.

2 – Michigan gained 1,339 solar industry jobs in 2016, representing a 48 percent increase in the state’s solar workforce.

A new National Solar Jobs Census from the nonprofit Solar Foundation says Michigan now has a total of 4,118 solar workers, up from 2,779 in 2015.

One out of every 50 new jobs added in the United States in 2016 was created by the solar industry, representing 2 percent of all new jobs.

Over the next 12 months, employers surveyed expect to see total solar industry employment increase by 10 percent.

In 2016, the five states with the most solar jobs were California, Massachusetts, Texas, Nevada, and Florida.
