Hudson River Pcb Pollution

Hudson River PCB Pollution is Affecting Wildlife Bird Species Introduction Studies over species in the Hudson River ecosystem have increased in recent years. This is done in return to the large amount of PCBs that have been found in the Hudson River. Polychlorinated Biphenyls or PCBs are a group of 209 organic chlorinated chemicals (DHS, 2016). PCBs are usually an oily liquid or a solid, which are colorless or have a light yellow color, with no smell or taste (DHS, 2016). PCBs are a created, manufactured chemical and to this day there are no signs of a natural source of PCBs (DHS, 2016). Since PCBs are so resistant to acids and bases they were used a lot for insulation in electrical equipment such as transformers and capacitors (Greenfacts, 2016). PCBs are also found in things like surface coatings, adhesives, flame retardants and paints (Greenfacts, 2016). After these items are thrown out the PCB waste can be released into the air. This is why many fear that PCB …show more content…

The study examined five different sites, three in which were contaminated and downstream from Hudson Falls, New York (McCarty and Secord, 1999). The final two sites were at Ithaca and Champlain, Champlain being located 5km upstream from Hudson Falls (McCarty and Secord, 1999). At each one of these sites, 25 to 35 nest boxes were placed along the river’s edge, each box placed in areas with plenty of suitable nesting material (McCarty and Secord, 1999). To measure the overall nest quality two measure were used, the mass and the number of feathers around the cup of the nest (McCarty and Secord, 1999). The mass would be weighed on the day the egg was laid and on the day the egg hatched (McCarty and Secord, 1999). While the number of feathers would be counted on the day the first egg was laid, when the clutch of the eggs was completed and on the day that the eggs hatched. (McCarty and Secord,

I hypothesized that the Conodoguinet Creek is polluted. Through my research I have found that the Conodoguinet Creek is not polluted. One reason it is not polluted is because most of the macroinvertebrates and crustaceans we found in the creek are pollution sensitive creatures. Another reason the creek is not polluted is the level of acidity and alkalinity is 7 which is a healthy number on the pH scale. If the acidity or alkalinity levels were high scientists would have to find a way to neutralize the acid and alkaline.

By creating experimental beach scenarios, negative and standard, Karpanty, et al, increased and decreased the amount of surface eggs to compare the availability and sufficiency to refuel Red Knots in the Delaware Bay area. They were able to determine that horseshoe crab eggs were sufficient and that Red Knots were not excluded when aggressive shorebirds also foraged on the experimental beach areas. The feeding times were mainly during the day and until high tide. It was observed that Red Knots foraged in high-density areas and along the wrack line, where horseshoe crab eggs were visible and easily accessible. Once that area was depleted, the Red Knots would move on to other horseshoe crab nesting areas.

My 8th grade class went to the Conodoguinet creek to test if there was any pollution in the creek water. Before we went my hypothesis was, “If we go to the Conodoguinet creek and test the water, then the creek will have little to any pollution in it because we haven’t had a monstrous storm in the past few months so there wouldn’t be an excessive amount of acid rainfall or runoff” There are three types of macroinvertebrates ( an invertebrate fauna - animal of a particular region - that can be captured by a soo - which is a certain net or sieve - ) that we were looking for, Group 1 ( which is pollution sensitive - they cannot have any pollution- ), Group 2 ( which is somewhat pollution tolerant - they can live with some pollution-) and Group

“Carried by snow melt, rain water, and groundwater, NPS pollution contributes sediments, nutrients (nitrogen and phosphorus), toxic substances, and pathogens to water bodies” (Maine Rivers 2005, ijc 2008). The Non Point Pollution generally due to stormwater in the downstream portion of the river; which are the most populated areas situated near the estuary;With the stormwater large amounts of pollutants are washed off to the river because of the impenetrable surfaces of that area which does not allow water to seep into the ground.  Other sources of  Nonpoint pollution are  seepage from broken sewage and  septic tanks, runoff from construction sites ,nutrients,sediments and chemicals from agricultural farms and roads. According to the report of International Joint Commission in 2008; “This untreated runoff may contain litter, dust, soil, oil and grease from roads, garden waste, chemicals, and nutrients and pathogens from animal feces and fertilizers” (IJC

Due to the negative effects caused from plastic it will always play a role in our environment. One hundred different chemicals have been created after the 1950s to the current day. Something people do not realize is that throwing a plastic wrapper on the ground will end up in a birds stomach, burning plastic in a fire will end up in the air we breathe, and recycling plastic will end up back in our homes.

Imagine what happens if we keep on polluting our planet? What happens to our future generation? Since plastic takes years to biodegrade, if we keep polluting our environment with plastic, then our future generation will suffer from the environment around them. It also means that plastic and other trash will continue polluting the ocean, which can cause thousands of sea animals to go extinct, providing us with less source of food. Not only sea animals, but animals all over the world might extinct or become endangered because of pollution.

That means that our use of plastic is not sustainable at all. Plastic does not biodegrade; it degrades very slowly which is a very big problem because the debris will apparently persist for centuries in the ocean. The garbage remains in the ocean until they break into smaller and smaller pieces. (Marine Turtle Newspaper,

The reason plastic is used in many products is because it can withstand up to tons of pressure per cm3, is cheap, is durable, and finally, there is no worry for discoloring. But these days, plastic is becoming a major problem the world has to deal with. Plastic is thrown into the ocean, and it is breaking down into very small pieces, and killing marine life, as they mistake those pieces to their prey. As a matter of fact, nearly all plastics are recyclable, but it 's the recycling companies ' machines that refuse to recycle that kind of plastic(eartheasy.com).   I. Plastic, what have you done?
