PCB LEVELS DOWN IN LAKE MICHIGAN FISH
September 29, J977 EdUo*: Bill Loemnitein
LANSING--Noteworthy decreases In levels of PCBs (polychlorinated biphenyls)
in Lake Michigan coho salmon have been shown, for the first time since monitoring
began five years ago, reports the Department of Natural Resources.
"This could mean our efforts are paying off, that PCBs are on their way out," says DNR Environmental Protection Bureau Chief William Turney.
The source of Turney's optimism 1$ a September U.S. Fish and Wildlife Service
report that pegs PCB levels In adult salmon taken last fall from east-central Lake
Michigan at 9.21 parts per million (ppm), compared to 10.77 ppm measured In a
similar catch from the same area In 1975.
Based on data gathered by the U.S. Fish and Wildlife Service Great Lakes Fish
Laboratory In Ann Arbor, the report also lists PCB level declines In Lake Michigan
chubs and lake trout. However, the only statistically significant, thus most
meaningful, decrease was that noted In coho, says John Hesse, Chief of the DNR's
Toxic Materials Section.

PCB LEMELS DOWN IN

Before voluntary restrictions on the sale of PCBs In 1971, chemicals of this group were commonly used to absorb heat In capacitors, transformers and hydraulic fluids, and as plasticizers or additives In carbonless reproduction papers.
Voluntary PCS sales restrictions came from Monsanto, Inc., the sole U.S. manufacturer, after It was clearly established that PCBs posed a health hazard to humans and animals.
Among the first creatures to show 111 effects were Great Lakes fish-eating birds such as herring gulls and terns, many of which died after eating PCS-contaminated
fish. "In Michigan, we found PCBs In the brains of dying gulls In concentrations as
high as 2,600 ppm," says Hesse, "which Is 10 times what wildlife researchers view as a lethal concentration." Fish accumulate PCBs In fatty tissue, sometimes to the point where they contain PCB levels thousands of times higher than the water In which
they swim. Also stricken with PCB poisoning have been mink at Michigan ranches, where the
animals died or had reproduction problems after being fed Great Lakes salmon. Testing this, researchers have Induced reproductive failure In mink by adding relatively low concentrations of PCBs to their normal diet.
Although there Is no record of negative human health effects from consumption of PCBs In this country, Hesse says, such effects were clearly shown In Japan after a 1968 accident In which PCBs were leaked Into rice oil. Some 1,200 persons fell 111 after eating the contaminated foodstuff.
The U.S. Food and Drug Administration has established 5 ppm as the maximum allowable concentration of PCBs In foodstuff to be sold for human consumption.
Although the PCB problem Is far from Michigan's alone, this state was among the first to Identify It and take steps to solve It, Turney says.
The DNR, with strong support from Governor Mllllken and the Michigan legislature, has played a key role In the drive to rid the environment of PCBs, which are extremely persistent In the food chain. That role has Included Intensified monitoring

and analysis to determine the extent of PCB contamination, and Implementation of
control programs that have virtually halted PCB losses from major Industrial and
commercial sources.
"Perhaps our efforts are being rewarded," says Turney, referring to the
report's conclusions. "Perhaps the days when we can stop advising people to linrtt
consumption of Great Lakes fish will come sooner than we've Imagined."
Many states, Including Michigan, have advised sport fishermen to limit consump
tion of PCB-contamlnated fish such as Great Lakes salmon, lake trout, steelhead
and brown trout to no more than one meal per week, and have advised women of
child-bearing age not to consume these fish at all.
Two other developments that should help are Michigan's new PCB law. Act 60 of
1976, which took effect April 1, 1977. It essentially prohibits the manufacture,
salt or use of PCBs In Michigan for all applications other than In transformers
and capacitors, "closed systems," as they are called.
Also, the recent Monsanto decision to halt all PCB distribution permanently In October Is looked upon favorably by state and federal officials, and Is expected to
augment the legislative mandate . Meanwhile, this month's Fish and Wildlife Service
report also notes a continued decline In DDT concentrations among the east-central
Lake Michigan salmon and among chubs and lake trout caught off Saugatuck.
And, the report lists a decline from past years In mercury levels measured
In Lake St. Clair walleyes.
"We'd like to believe these welcome results are from some of our past efforts,"
Turney says.

HEAVY RAINS PRODUCE MANY WILD MUSHROOMS

LANSING--Heavy rains during the past two weeks have produced a super-abundance
of wild Mushrooms, reports the Department of Natural Resources. The situation
presents both an opportunity and a hazard, depending on the knowledge of the
Individual mushroom hunter.
"There are excellent eating varieties available," says Bill Mullendore of
the DNR, an avid amateur mushroom hunter. "Trouble Is, there are also many 'doubtful'
and downright poisonous varieties growing In many of the same places. It takes
some knowledge and discrimination to select the 'right' kinds."
Two years ago, when southern Michigan experienced a similar wet fall and wild
mushrooms sprouted In profusion, there were several poisoning deaths and many more
cases of serious Illness among people who didn't "know their mushrooms" and picked
the wrong varieties.
In the Lansing area, and probably In many other places, an all-white--caps,
gills and stems--mushroom has fruited In great profusion on lawns. In pastures,
on golf courses and along roads. This species Is not the deadly amanita verna
(Destroying Angel) but resembles It closely enough that only an expert can tell the
difference.
"Best rule for the amateur collector Is to leave any all-white, smooth-capped,
umbrella-shaped mushrooms strictly alone," Mullendore advises. The Destroying Angel
normally grows In forests, but there's always the chance that It may show up where
It Isn't supposed to be. I have found them on the golf course behind my home." The shaggy mane (coprlnus comatus), which Is choice and very abundant this fall.
Is all-white In Its edible stage. In that stage. It Is shaped like an upside-down
bowling pin, not an umbrella, and has feathery scales on the cap.
"Mushroom hunting Is a safe, rewarding recreation for those who know what they
are doing," Mullendore concludes. "But It's a risky venture for the person who finds
a bunch of mushrooms In his backyard and decides to take a chance that they are safe
to eat. If you don't absolutely know that a mushroom Is edible, check It out with

'Even though the price of commercially grown mushrooms In the supermarket Is
pretty high these days. It's very low compared to the medical bills or worse that can result from Ignorance In eating wild ones."

PUBLIC PANEL REVIEWS SOLID HASTE PROGRAM
LANSING--A "Public Response Panel," representing Michigan citizen organizations,
business and government, met for the second time In Lansing September 28 to review
progress and development of the state's solid waste and resource recovery plan. The panel, organized by the Department of Natural Resources, Is composed of
delegates from groups and agencies with special Interest In the future disposal
or reuse of household and Industrial refuse.
Solid waste Is being generated In Michigan atthe rate of 16 million tons a
year, say state officials. Panel members represent the Michigan United Conservation Clubs, the Michigan
Manufacturers' Association, glass, steel and packaging companies, the automobile
Industry, East and West Michigan Environmental Action Councils, townships, counties
and municipalities, the legislature and the news media.
"There Is an Imnedlate need for better understanding and awareness of solid waste problems and control programs by every citizen," says engineer Tom Work of
the DNR Resource Recovery Division. "We're hopeful that meetings of the Response
Panel will accelerate that understanding and public awareness."

YOU CAN SAY GOOD NIGHT TO MICHIGAN'S SNAKES

LANSING---Michigan's snakes are getting ready for a long winter's nap. That's
the word from a retired Department of Natural Resources game biologist and recognized herpetologist.
Donald F. Swltzenberg, who was In charge of the DNR's Cuslno Wildlife
Experiment Station at Shlngleton In the Upper Peninsula for 11 years, says snakes
are getting ready to hibernate.
"Last year we had a cold fall. If the fall weather Is warm this year, you'll see more snakes," he says.
That's because the snakes want to enjoy the warm fall sunshine before going
underground for the winter, according to Swltzenberg. Summer weather Is usually
too hot for the snakes to be out and visible, but a warm fall day Is just right. "The active season of snakes In Michigan Is extremely short," he points out.
"Michigan snakes come out of hibernation In late April or early Nay, and gather
around their winter denning grounds In late September or early October. At such
times, snakes may be seen In unbelievable numbers." Seventeen species and subspecies of snakes are found In Michigan. Some of these,
such as the garter and water snakes, are extremely common In many parts of the
state. Others are so rare or secretive that they are seldom seen by most people. "All but one of Michigan's snakes are harmless," Swltzenberg points out.
"The only poisonous species, the Massasauga rattlesnake. Is confined to the Lower
Peninsula, but has been known to range as far north as Bols Blanc Island, near the
Mackinac Bridge." Although belonging to a group of snakes that Is as deadly as any In the world,
the Massasauga Is not considered highly dangerous to man.
"Snakes occupy a variety of habitats In Michigan as elsewhere," he says. "The
water snakes are distinctive In frequenting almost entirely the borders of lakes,
ponds and streams, and are rarely found far away from such places. Several of the smaller species spend most of their time under logs, stones,
and other such hideouts, coming out only to feed. (more)

"Sam climb trees with greet agility," Swltzenberg points out. "The ease
with which the pilot blacksnake, for Instance, can ascend the vertical surface
of a large tree trunk Is a sight to behold."
But for now, snakes are just looking for a nice warm place to spend the winter.
"They have to get below the frost line," Swltzenberg adds, "or else they'll
freeze.
Swltzenberg retired from the DNR In 1961 after 23 years service. He now resides
In Okemos.

THERE'S STILL TIME FOR A COLOR TOUR
LANSING--If you're planning a color tour In northern Michigan, the Department
of Natural Resources advises going during the next two weeks.
William 0. Schwarz, DNR District Business Executive In Cadillac, says, "Anytime
during the next couple of weeks will be excellent for a color tour In the northern
Lower Peninsula." He reports foliage of 50 percent color now, and although "not particularly
dramatic," Schwarz says there Is still a lot of color to be seen. "Lowland maples and cherry trees have already turned," he says. "Oak Is still
green and sumac Is turning now."
Farther north, Wesley Lehman, DNR Regional Forest Supervisor In Marquette, says
the color has peaked In the Upper Peninsula. `Last weekend was the peak," Lehman says. "It's still fairly nice though, with
about a week or two left for color tours before the leaves fall."
Lehman notes that the color Is not as brilliant as It has been In former years. "The maples turned earlier," he says. "White birch, yellow birch and aspen
came on quite early too." He points out that aspen colors still are at their height and "If you get some
sunshine on the trees. It's still really sensational." ###
