Anglers around the Great Lakes region are starting to pay more attention to some of the smallest
and most humble pieces of gear in their tackle box – lead weights and jigs. Recent research shows
lead fishing tackle is killing eagles, loons and other water birds. The Great Lakes Radio
Consortium’s Stephanie Hemphill reports:


Outside a Gander Mountain outdoor gear store in Duluth, Minnesota, there’s a steady stream of
people dropping lead tackle into a cardboard box. They bring it in plastic bags, in jars, and in the
original wrappers. They walk away with a small supply of sinkers made of steel, tungsten, or
bismuth.


Jim Simmons says he doesn’t use much lead tackle, but he’s ready to get rid of most of his supply.


“Well, I just brought in one package of split shot,” he says.


“What did they give you in exchange?”


“Some jigs, a couple of weights.”


“What are they made of?”


“They’re made of steel, and one is ceramic.”


“How do you think it will work?”


“I think it’ll work fine. We’ll try it out, give it a shot anyway!”


Inside the store, another angler says he doesn’t want to poison loons, but he isn’t ready to give up
his investment in lead weights.


“I have the tackle so I might as well use it,” he says. “Maybe I’ll switch to the other stuff, as I use
up the old.”


But a lot of anglers simply don’t realize lead tackle could be hurting wildlife.


No one uses lead shot for hunting anymore. It was banned years ago. But loons, eagles, and other
birds are still dying from lead poisoning.


Eagles can be poisoned by eating birds that have eaten lead.


Loons dive to the bottom of lakes and pick up pebbles and eat them. The pebbles go to the bird’s
gizzard, where they help grind up the small fish they eat. If they happen to swallow a lead sinker
or jig that some angler has lost, it only takes a small piece to poison the bird.


Some studies in New England have found as many as half the loons could be dying from lead
poisoning. In the Midwest, the figure is lower, but more research is underway.


Dave Zentner loves to fish. He’s an active member of the Isaac Walton League, a national
conservation organization.


He’s trying out the non-lead jigs for the first time, from a canoe in the St. Louis River near Duluth.
He keeps getting his line caught in the rocks on the bottom.


“There’s nothing that feels differently to me about this tungsten jig. It fishes with that twister-tail
just like any lead jig I would have hooked on before. And it sure as heck has been effective in
getting me snagged up!”


Zentner casts over and over, and loses his jig in the rocks. He reaches for another one, made of
bismuth.


“We left a piece of fishing gear down there,” he says. “And if a loon or a merganser decides to try
to eat it, we haven’t left something that’s going to make it sick.”


Dave Zentner was hoping the Minnesota legislature would ban lead tackle. Small lead sinkers are
banned in New Hampshire, Maine, and national parks in Canada. A New York ban takes effect
next spring. But in Minnesota, fishing groups and tackle manufacturers fought the bill.


So instead, the state is running a voluntary exchange program, and hoping to raise awareness
among anglers.


Zentner says some people won’t want to spend a little extra for the bismuth and tungsten weights
that behave like lead. But he says prices will come down as the demand goes up.


“And let’s make a little sacrifice, even if the price is a little higher,” he says. “We buy RVs and
ATVs and boats and motors, we spend thousands and thousands of dollars. And this is a
proposition that’s miniscule compared to that one.”


So far, a few tackle manufacturers have added non-lead alternatives to their product lines. But
there aren’t nearly as many choices as the lead products offer. Manufacturers are reluctant to re-
tool until they know people will buy the new lead-free products.


It could take years to persuade large numbers of anglers to switch from their tried and true gear.
But Dave Zentner says that’s what he’s going to try to do.


“We don’t want to put the tackle people out of business, we want them to stay in business,” he
says. “But we’re simply saying – it appears there’s a problem; let’s go to work on it, let’s educate,
let’s experiment, let’s work together.”


Finally Zentner proves the non-lead tackle works by catching a small-mouth bass.


“And it is a little guy!”

The COMPLEXITIES OF ISSUING FISH ADVISORIES (Part I)

  • Fish is healthy food, but contamination from pollution means people should limit the amount of inland lake and river fish they eat. Photo by Lester Graham.

There are three major questions often asked when considering the environmental health of a body of water. Can you drink the water? Can you swim in it? And… can you eat the fish? Often the answer to the last question is very complicated. The Great Lakes Radio Consortium’s Lester Graham has the first report in a two-part series on the fish that ends up on your table:

There are three major questions often asked when considering the
environmental health of a body of water. Can you drink the water? Can you
swim in it? And… can you eat the fish? Often the answer to the last
question is very complicated. The Great Lakes Radio Consortium’s Lester
Graham has the first report in a two-part series on the fish that ends up on
your table:


Mark Ford goes fishing almost every weekday. This day, he’s at a small
marina off of Lake Michigan. He’s carrying several rods and reels and a
couple of tackle boxes with him to an old dock…


Lester Graham: “Now, what do you fish for?”


Mark Ford: “Right now, whatever bites on the hook. Basically, I fish for bass,
catfish, walleye.”


This day, he’s just testing some new gear…


“Set my drag. Too loose.”


When Ford got his fishing license, he also got a guide telling him that the fish
he eats is contaminated. All inland lakes have some level of contamination
which could include pesticides, PCBs, and mercury.


Ford has a pretty good idea about what to do to reduce his exposure to the contaminants when he eats the fish..


“Yeah, first thing you want to do is cut off all excess fat to get away from a lot of the chemical
pollutants that’s not in the actual meat of the fish. That’s where most of the chemicals lie, in the fat. So, you cut that off and get to cookin’.”


Ford’s preparation is a good start. Trimming the fat will reduce exposure to PCBs and
similar compounds that are stored in fatty tissue. And just cooking the fish reduces some of the exposure to contaminants. But if a contaminant such as methyl mercury is present in the flesh of the fish, no amount of rinsing, boiling or frying will change that.


Unfortunately, many anglers are not as well informed as Mark Ford. A study in Canada
found a lot fishers don’t understand the contaminants or what to do about them. They judge
whether the fish is safe to eat by how well it fights on the line… by the color of the
flesh… or by the clearness of the eye. None of those things is an indicator of whether a fish is contaminated by toxic chemicals.


Alan Hayton is with the Ontario Ministry of the Environment. He says how much fish are
contaminated depends on the body of water. A ban on PCBs in manufacturing
has helped, although there are still decades worth of the pollutant in some lake
sediments. Agricultural pesticide restrictions and bans have helped reduce
contaminants in some other lakes.


“Well, if you want – are fish getting better or worse? Certainly over the years,
when you look at the Great Lakes, there’s been a considerable decline in the level of
contaminants in fish. Many of the inland lakes, both in Ontario and elsewhere – not
just around the Great Lakes, but elsewhere – there’s mercury in those fish. Mercury
concentrations don’t appear to be changing. They seem to be quite stable.
So, we find that in quite a high proportion of the inland lakes there are some consumption
restrictions.”


Mercury remains a problem because as coal-fired power plants release mercury
into the air… it’s brought down into watersheds by rain. There the problem is
complicated in some areas by any number of factors, including some bacteria that transform
simple mercury into the more toxic methyl mercury.


So, some bodies of water, such as the Great Lakes, have lower levels of some
pollutants, but some other contaminants are just as bad as ever. To complicate things
even more, some fish are more contaminated than others.


Faith Shottenfeld is with the New York State Department of Health.


“You know, it’s complicated because it’s going to vary from state to state, from body of
water to body of water and from fish species to fish species.”


Shottenfeld says that makes getting the message to anglers all the more difficult.
States are trying to figure out how to get the information to the people who eat
the fish, but there are very few general guidelines.


“So, I think that the best way to work your way through the complexities
is to really have a dialogue with somebody who understands the advisories and can
help you figure out what you need to do.”


But generally speaking, eating smaller fish, and limiting sport fish meals from local lakes to about once a week for men and once a month for women helps.


Angler Mark Ford says he’s not worried. He says to him, the health benefits of
fish offset the health risks of the contaminants.


“A month, I’d say I eat about twelve to 15 pounds of fish. I eat a lot of fish.
I like fish. Fish is healthy for you, too. It’s low in cholesterol if you cut the fat away from
it. It’s good brain food. That’s scientifically proven. And, if you prepare it
right, it tastes good!”


And Ford says he’s healthy. But experts indicate it’s hard to say what long-term
exposure to the contaminants in sport fish from area lakes will mean to human
health. They caution that children and women of child-bearing age should severely
restrict their intake of sport fish because the contaminants can damage the
development of fetuses and children.

Health officials are trying to get the word out about contaminants in sport fish. But the
issue is complicated. So, it’s difficult to give people an easy answer on how to reduce
the health risk. The Great Lakes Radio Consortium’s Lester Graham reports:


Sport fish contain contaminants such as PCBs, pesticides, and mercury. But the amount
of contaminants in a fish depends on the body of water, the species of fish, and
even the age of the fish. So, there are very few general guidelines. That makes it difficult for
health officials to tell people what’s best for them.


Faith Shottenfeld is with the New York State Department of Public Health. She says safe
consumption levels vary.


“For some fish, a meal a week, a meal a month. You certainly can talk in general
about eating smaller fish because as you move your way up the food chain, you
know, the bigger fish eat the little fish so they get more and more and more chemicals,
but there are some examples of smaller fish that are highly contaminated.”


Shottenfeld notes that children and women of childbearing age are at more risk
from ill effects of the contaminants in fish than men. She says the best bet is to talk to someone
who’s familiar with your state and area’s fish consumption advisories.

PROTECTING CHILDREN FROM TAINTED FISH (Part II)

The people most at risk from contaminants in fish often don’t know it. Different chemicals found in fish from many inland lakes, including the Great Lakes, can be harmful to human development.

The people most at risk from contaminants in fish often don’t know it.
Different chemicals found in fish from many inland lakes, including the
Great Lakes, can be harmful to human development. State governments
issue fish consumption advisories that recommend limiting
eating such fish. In the second of a two part series on contaminants in
fish… the Great Lakes Radio Consortium’s Lester Graham reports that not
everyone learns of the advisories:


Horace Phillips likes to fish. He can often be found casting a line into a
lagoon off of Lake Michigan on Chicago’s south side. He says he and a lot of
his fishing buddies know about the fish consumption advisories, but he doesn’t
think he eats enough to matter…


“Sure, it’s always good to know, but, as I say, I’m not consuming that much fish.”


That’s because Phillips gives away much of the fish he catches. Like a lot of
anglers, he enjoys the sport, and shares what he catches with friends and
relatives. He doesn’t remember getting a fishing guide when he got his fishing
license, but the retailer was supposed to give him one. It not only outlines limits
on the amount of fish an angler can take, but also includes recommendations
on how much fish he should eat in a given month.


But Phillips says he thinks he learned about fish contaminants from the
newspaper. He never really thought about passing on the warning to people
with whom he shares his fish.


“I suppose the same literature that’s available to me is also available to them.”


But often the people who prepare the fish or who eat the fish don’t have a
clue that there’s anything wrong with the fish.


We should note here that fish is nutritious. It’s a good low-fat, lower calorie
source of protein. Eating fish instead of higher-fat and cholesterol laden foods
is believed to help lower the risk of heart disease, high blood pressure,
diabetes and several forms of cancer. Pretty good food, fish.


But some fish contain PCBs – polychlorinated biphenyls – believed to cause
cancer. Chlordane, a pesticide, has been found in fish. And methyl mercury is
found in some fish. These chemicals can cause serious health problems,
especially for children and fetuses. They can disrupt the systems that
coordinate the nervous system, the brain, and the reproductive system.


Studies have shown women store some of these chemicals in their
fat tissue until they become pregnant. Then, those chemicals are passed
to the child they’re carrying. Studies have indicated that of mothers
who ate three or more fish meals a month, those with the highest exposure
gave birth to children with health problems.


They had significant delays in neuromuscular and neurological development.
Those children continued to show short-term memory problems at age four… and
significant reduction in IQ and academic skills at age seven.


Barbara Knuth is a professor of Natural Resource Policy and Management at
Cornell University. She says given the health concerns with eating too much contaminated fish, the information about restrictions needs to be more widely distributed.


“Where we need to focus effort now is not so much on the angler, but we need to be focusing
on the people with whom they’re sharing those fish, the women, their wives, mothers
of childbearing age, women of childbearing age, children, because that’s where we now know,
scientists now know – who are studying this – where the real health effects are.”


But where to start? After all, the fish might come from a friend… it might be at the deli… it could be on the plate at a local restaurant. There are no rules requiring a notice that fish is from a lake, or the ocean, or farm-raised. So, how do you get the word out?


One federal agency is working to get the information to those at highest risk by going through their doctor. Steve Blackwell is with the Agency for Toxic Substances and Disease Registry.


“We’ve taken on trying to reach health care providers that are serving the target
population, the most at-risk population of women, children, pregnant women and reach those
groups such as OBGYNs, family physicians, pediatricians with this information to help raise
awareness within that group that serves the at-risk population to try and make sure that they’re receiving the message and they’re not telling their patients something different from what the patients may be hearing outside that realm.”


Whether the doctors are actually passing on the concerns about contaminated fish is a
whole other question. But assuming they are, there’s still another concern. Many of the women who are most at risk might not see a doctor until the day the baby is due. Poor women… the very same women who might rely on fishing for a good part of their diet… might not be told
about the risks.


And so their children are born into poverty… and the added burden of chemicals that can hurt their development. Blackwell says reaching those women is something the federal government cannot do alone.


“You want to reach those people through local leaders, through churches, through
institutions that aren’t medical.”


And that’s best done, Blackwell says, by local government, not the federal
government. But state budgets are strapped. And, in some cases, states are
reluctant to raise awareness of an issue that they really can’t fix. A source within
a state agency told us that an higher-ranking official indicated to
him that he didn’t want to assign a full-time person to work on fish contamination
awareness alone because it would send the wrong political message. Another state stopped publishing fish consumption advisories as a budget cutting move… that is… until local reporters exposed that particular budget cut.


In short, warning pregnant women and women of childbearing age about the dangers of
eating too much contaminated fish and how that could damage their children’s
intellectual and physical development has not gotten enough attention yet to become a
political priority.

Health and environmental agencies are struggling to find the best way to alert people,

Some states cut budgets, including money for publishing fish consumption advisories.
It’s curtailing the efforts of health officials to tell families that children and women of
childbearing age should severely restrict their intake of sport fish.


Most sport fish contain levels of pesticides, PCBs, and/or mercury high enough to
cause neurological and mental developmental problems in children. Barbara Knuth
is a professor at Cornell University.


“Budgets are limited and until the time when resources are made available through state
governments, through EPA, even through foundations to fund both communication efforts and
evaluation and testing of those efforts to improve them, I think it’s still going to be a struggling
effort.”


Knuth says relatively small investments in information now could prevent great costs to
society and children’s lives later.
