The invasion of PCB & Zebra Mussels by Fionnuala Selby https://padlet.com/fselby0616/fwo6qh0awho7g6r6 By: Fionnuala Selby & Riley Craig en-us 2021-06-11 12:46:54 UTC 2025-04-27 20:36:10 UTC hello@padlet.com https://padlet.net/icons/png/1f41f.png Key Causes fselby0616 https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1609835630 For 30 years ending in the late 1970s, the General Electric Company discharged as much as 1.3 million pounds of PCBs into the Hudson River from its manufacturing plants. The city would also often discharge untreated sewage into the river causing even more problems. Bodies have also been found floating in the East and Hudson Rivers in the past few years so the disposing of bodies in the river is also causing particulate matter, also called pollution, which is the introduction of contaminants into an enviroment. Human introductions of invasive species such as the zebra mussel, which are an important biotic factor because they are a living organism in the ecosystem, have caused incredible changes, which probably will not be reversed for decades, if ever. ]]> 2021-06-16 12:33:27 UTC https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1609835630 Feeding Relationships rcraig09051 https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1609851734 Feeding relationships have changed due to humans being advised to not eat fish, and the Zebra Mussels being in the Hudson. The Humans are at the top of food chain, the zebra mussels have changed the feeding relationships because they were helping with the reproduction of algae which produces harmful toxins for both the fish and humans. The harmful toxins are putting the larger predatory fish in harm. A predatory fish is a fish that is at the top of their food chain. The harmful toxins put the small fish though in large danger than it did the bigger fish but, that meant the big fish lost food. ]]> 2021-06-16 12:42:25 UTC https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1609851734 Fun Facts rcraig09051 https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1609864146 - The Hudson River became America's first superhighway after the Erie Canal was built. 
- Sometimes Humpback Whales or Seahorses like to stray into the Hudson River from the Atlantic. ]]> 2021-06-16 12:48:53 UTC https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1609864146 Long Term Problems fselby0616 https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1609879263 The Hudson has lots of long term problems including being known to cause illnesses and even a cancer risk due to how contaminated and polluted the water is. There are high levels of pcb in fish that are not decreasing. The dumping of PCB in the Hudson started in 1947 and ended in 1977 due to them getting caught. There are still high levels of PCB to this day.  The Hudson River is also not cleaning itself, so the  Pcb is staying in Hudson. The Zebra Mussels help with producing a toxin from algae that is very harmful to humans and animals. Places with Zebra Mussels have more algae and more toxins from that algae. Zebra Mussels are an invasive species to the Hudson because they are causing ecological damage in a place they are not supposed to be in.  ]]> 2021-06-16 12:56:28 UTC https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1609879263 Pcb pouring from general electric rcraig09051 https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1609993881 2021-06-16 13:43:28 UTC https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1609993881 Humpbacks in the Hudson rcraig09051 https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1610006817 2021-06-16 13:48:32 UTC https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1610006817 Fish advisory flyer rcraig09051 https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1610066377 2021-06-16 14:12:10 UTC https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1610066377 rcraig09051 https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1610103290 2021-06-16 14:27:03 UTC https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1610103290 Hudson prior to Zebra Mussel invasion rcraig09051 https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1610106792 2021-06-16 14:28:24 UTC https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1610106792 Hudson after Zebra Mussel invasion rcraig09051 https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1610108406 2021-06-16 14:29:01 UTC https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1610108406 rcraig09051 https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1610111023 2021-06-16 14:30:06 UTC https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1610111023 rcraig09051 https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1610575051 2021-06-16 18:08:57 UTC https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1610575051 rcraig09051 https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1610575395 2021-06-16 18:09:08 UTC https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1610575395 rcraig09051 https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1610577954 2021-06-16 18:10:28 UTC https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1610577954 rcraig09051 https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1610579651 2021-06-16 18:11:28 UTC https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1610579651 rcraig09051 https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1610580270 2021-06-16 18:11:48 UTC https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1610580270 rcraig09051 https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1610580763 2021-06-16 18:12:05 UTC https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1610580763 rcraig09051 https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1610582845 2021-06-16 18:13:06 UTC https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1610582845 rcraig09051 https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1610598040 Food Web]]> 2021-06-16 18:21:51 UTC https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1610598040 Changes that have occurred to the ecosystem fselby0616 https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1612052034 As we know PCBs are a group of highly toxic compounds that are known to cause cancer, birth defects, growth impairment, behavioral changes, hormonal imbalances, damage to the developing brain, and increased susceptibility to disease in animals. These chemicals make their way up the food chain and become stored in the tissues of wildlife and fish, posing a health threat if people and other animals consume them. New York State created an 'eat none' (meaning people must release fish if caught) advisory that has been in place for about 30 years.

Some things you can do are...
-  Use non-toxic cleaning supplies. The substances that go down your drain will eventually reach a body of water, affecting all the fish and invertebrates in the vicinity.
- Carry out what you carry in. Leave areas by the river as clean than they were when you arrived.
- Prevent hazardous waste from reaching the river. Report chemical spills on roadways or bridges to hazardous waste teams.
- Don't pick up plant and animal hitchhikers. Reduce the spread of invasive species, such as zebra mussels, by inspecting and hosing down your boat.

Right now the Hudson River looks clean but the real problem is PCBs contamination. With everyones help eventually the Hudson can be clean and chemical free and we may even be able to fish without having to throw the fishes back in the water.]]> 2021-06-17 12:15:28 UTC https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1612093721 Hudson River PCB informative website rcraig09051 https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1612103095 2021-06-17 12:21:44 UTC https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1612103095 The ferry's and steamboats polluting the water near New York City rcraig09051 https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1612123993 2021-06-17 12:35:12 UTC https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1612123993 Voiceover fselby0616 https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1612172444 2021-06-17 13:01:30 UTC https://padlet.com/fselby0616/fwo6qh0awho7g6r6/wish/1612172444
