In this file photo taken on October 31, 2018 mussels are pictured in the port of Grandcamp-Maisy on the Normandy coast, northwestern France. As mussels filter out microplastic particles from the water in addition to food particles, a microplastic investigation of the mussels allows indirect conclusions to be drawn about pollution in their respective areas of origin. Mussels constantly pump water to feed and breathe. The rate of reproduction and spread of zebra mussels make them efficient cleaners of Great Lakes water, but whether that’s a positive or negative thing depends on who you’re asking.

The mussels, placed in fish traps, are submerged in the waters for a month before researchers dissect them to determine what chemical substances lurk in their tissues. As they pump and filter the water through their gills in order to feed and breathe, mussels store almost everything else that passes through—which is why strict health rules apply for those destined for human consumption. "Eutrophication... is the biggest problem of the Baltic Sea, the most urgent one," says project head Lena Tasse. The nutrients in these substances encourage the proliferation of algae, which in turn starves the water of oxygen, upsetting the ecosystem. Like canaries in a coal mine, mussels have long been used as "bio-indicators" of the health of the seas, lakes and rivers they inhabit.

This was removed from a lake and shows zebra mussel buildup inside the intake water line. Little-known pollutants can turn up to join the usual suspects, with increasing attention paid to microplastics containing bisphenol A and phthalates, both thought to be endocrine disruptors. draw in seawater and filter out phytoplankton and sediments Zebra Mussel Filter Systems model 5100L lake installation. Rights: Revive Our Gulf, The Mussel Reef Restoration Trust. They draw in seawater and filter out phytoplankton and sediments, cleaning the water as they go. Broken down by bacteria, excess nutrients produce ammonia that, new studies indicate, may be deadly to mussels even at … Mussels play an important role in nutrient cycling, removing organic matter from the water, excreting dissolved nutrients back into it, and depositing these nutrients in the sediment. Excess nutrients wreck the chemistry and deplete the oxygen. Models for weather that include data from amateur stations? Exactly what they eat is a bit of a mystery, and it probably varies by species and age of the mussel. As they pump and filter the water through their gills in order to feed and breathe, mussels store almost everything else that passes through — which is why strict health rules apply for those destined for human consumption. Meistertzheim thinks not. A recent report by WWF said that humans ingest an average of five grammes of microplastics a week—about the weight of a credit card. Note that the video does not have a soundtrack. Mussels living in waterways affected by eutrophication—often marked by abundant algae—are also fit for human consumption, researchers say. If you place mussels that you know are relatively uncontaminated in the water, and you let them do their thing for a few months, you can collect them and measure the chemicals they filtered from the water during that time. "It's a real model of bioaccumulation of pollutants generally speaking." A 2018 study published in the journal Environmental Pollution, based on samples from British coastlines and supermarkets, estimated that every 100 grammes (3.5 ounces) of mussels contained 70 tiny pieces of plastic. Generally, most native filter feeders improve water quality by taking in algae or nutrients from the water and incorporating it into their tissues or depositing it on the water’s bottom.
