Side effects of Mercury
Mercury, a heavy, silver metal forms as a liquid at room temperature and is deadly to animals, especially to humans. The Environmental Protection Agency or EPA discovered that short-term exposure to mercury found in water can result in health hazards. Kidney damage can happen when exposed to mercury at levels beyond the contaminant level of 0.002 ppm. The toxic substance can also result to brain damage in children and hinder brain development in developing babies. Mercury can also attack the immune system and damage heart function in adults.
Since 1970 the mercury content found in Greta Lakes based fish continued to drop progressively. The reduction of mercury was the result of stricter Midwestern smokestacks regulations and the closure of coal-fired manufacturing plants. Also, technology provides massive benefit for pollution prevention.
Research scientist at the Environment and Climate Change Canada, Agnes Richards said, “We’ve been monitoring since the 1970s and the (mercury contamination) trends overall have been declining, as have been the emissions of mercury into the atmosphere and deposition into the lakes.”
Richards also added, “We decided to look at recent trends, from 2000 to 2015. What we found is, at some specific sites, trends have reversed.”
Reversal of the trend
In the past years, the trend started to change. Scientist found mercury level increasing in several Great Lakes fish like walleye and lake trout. Another peculiar case in the toxic mercury reports shows that not all fishes are affected. Researchers are still conducting more studies to find out the reason for the incidence.
Joseph Bohr, the aquatic biologist for the Michigan Department of Environmental Quality’s Water Resources Division claimed that mercury level in some fish continues to rise. He said (in the same article), “Out of 19 data sets, we see eight where we can see a significant trend.”
In Lake Michigan, Bohr mentioned that walleye and lake trout in the Grand Traverse bays show an increase of mercury content. Scientists can also see the same trend in Lake Huron in the walleye from Saginaw Bay and the lake trout found in Thunder Bay. Lake Erie also shows mercury level rising. The aquatic biologist said that the average increase of mercury level reaches up to 2% annually.
For the meantime, the increasing level of mercury toxicity remains in isolated areas.
Scientist Hypothesis-are storms to blame?
Ecotoxicologist of Environmental Canada, Shane De Solla believed that the warming of the Great Lakes shows a key factor in the trend. De Solla, the co-author of the research said, “The lakes are slightly warmer, and that increases the production of methyl mercury.”
Richards also mentioned that the region’s regular strong storms in the past years can also affect the Great Lakes. She said, “That results in a lot of flooding, and the re-suspension of sediments, what was buried before can become exposed, and that can increase the conversion of mercury to methylmercury.”
Meanwhile, Bohr mentioned about the invasive species which “significantly changed the food web.” These invasive species significantly altered the fish diets.
He said that in Saginaw, Thunder bays, and Grand Traverse carp are not showing any increase in mercury levels. Bohr added that in the Detroit River and St. Clair River carp are even seen decreases in mercury. He believed that the findings show important clues because carp being bottom feeders and eat differently from big sports fish.
Bohr said that carp are “low on the food chain” and “mucking around on the bottom eating insects, basically.”
De Solla believed that the mercury level in the Great Lakes will not cause any “catastrophic in the next little while.” However, if it continues to increase then “it could become a problem again.”
Mercury levels found in the fishes remains below the US Environmental Protection thresholds. Nevertheless, researchers want to establish if the reported mercury level is a temporary condition or will cause an environmental concern.
Billions worth of fish industry possibly effected
The outcome can greatly affect Michigan’s fishing industry. The data of The Michigan Department of Natural Resources concluded that anglers spent at least $2.4 billion in equipment and trip-related expenditure in 2011.

Witnesses account say that the second mate of Augusta spotted Lady Elgin 30 minutes before the collision. However, the schooner did change its course until it was too late. The smaller vessel managed to correct its course 10 minutes before the collision.
When Augusta collided with Lady Elgin, there was music in the forward cabin. The captain of Augusta sailed away thinking that their vessel sustained more damage than the larger vessel. But Augusta torn a big part of the Lady Elgin, the crew lowered a lifeboat but was not secured. The lifeboat just floated away before passengers could go onboard.
A massive gale-force storm hit Carl Bradley on November 18 after a haul delivery in Gary, Indiana. The vessel was on its way heading north in the upper part of Lake Michigan., The freighter began cracking in to around 5:30 pm when the storm’s wind reaching 65 miles per hour and waves began to soar up to 20 feet tall.
The crew made three radio calls of Mayday but rescuers reached the freighter too late, only two survived from the 35 crewmen on board the Carl Bradley.
Records show that Niagara was the finest steamers of its era. The side-wheeled vessel was built in 1846 in Buffalo New York and serves a main transportation for both passengers and good in the Great Lakes.
However, on a tragic day of September 24, 1856, the steamship caught fire around 6:00 pm. The fire started in the engine room but the cause of the fire remains a mystery until today. One theory surfaces about the incident is that some flammable cargo may have cause the fire.
Most of the crew and passengers were able to jump from Niagara. Nearby ships later rescued the stranded people. However, 60 out of the 300 passengers died on that day and the entire ship was lost in the water.
One of the most memorable shipwrecks in Lake Michigan was L.R. Dotty. The vessel was one of the last wooden steamships to set sail on the Great Lakes in 1893. Steel become the standards for newer models. The 291-foot steamer had reinforced steels and very much sturdy according to the standards.
L.R. Dotty also has a powerful and huge engine but did not have any electricity of any up to date communication apparatus. The vessel was no match for the vicious storm on October 25, 1898. On that same day, several vessels on the lake perished including Chicago boardwalk and Milwaukee break wall. The storm claimed all the lives and cargo onboard of L.R. Dotty. The ship was later discovered after 112 years since it sank in the bottom of Lake Michigan.

Traverse City, (my favorite city in the world) lies on the shores of Lake Michigan’s Grand Traverse Bays and is the largest city in the 21-county of Northern Michigan. If you are heading “Up North” and want to “explore some of Northern Michigan’s Best Beaches“, then make sure to read our article.
TC is the largest producer of tart cherries in the United States reportedly, however rumors swirl about the Cherry Festival bringing in cherries from Washington for the National Cherry Festival…. The festival attracts at least 500,000 tourists for a full week in July. Talk about “fudgy central”. If you dont know what the term “fudgy” means, it means you’re not a local. People visiting always seem to stop at some of the fudge shops that are scattered across TC.
French voyagers named the city after the Grand Traverse Bay as “La Grande Traverse.” It means the long crossing across the mouth of the bay. In 1839, Rev Peter Doughtery started the first permanent settlement in Traverse City.
