Newtown creek is a 3.8-mile waterway located on the border of Brooklyn and Queens in New York City and was once a busy center for industrial activity. More than 50 factories were located along its banks, including oil refineries, petrochemical plants, sawmills, and lumber and coal yards. The Creek was also the site of one of the largest oil spill in the U.S. (EPA, 2007). As a consequence, the soil surrounding the area became polluted with toxic heavy metals and polycyclic aromatic hydrocarbons (PAHs) and was declared a Superfund site. The Superfund Program requires responsible parties to perform cleanups or reimburse the government for cleanups led by EPA. Superfund sites are hazardous to human health and to the environment. benz[a]anthracene, …show more content…
When the moisture, temperature, and nutrients are suitable, spores freed from a mushroom germinate into threads of cells called hyphae. As each hypha grows and branches, it forms connections with other hyphae from compatible spores to create mycelia, which mature, gathering nutrients and moisture (Stamets, 2005). The mycelia of the Stropharia rugoso-annulata, otherwise known as the garden giant, are bestowed upon the title of mycoremediator. Its mycelia secrete enzymes such as manganese dependent peroxidase, an enzyme that mineralizes wood and is particularly efficient in breaking hydrocarbon bonds; this mineralization indicates a complete breakdown of the PAHs (Morelli et al. 2012). This fungus has been proven to modify soil permeability and soil ion exchange and to detoxify contaminated soil. It has been identified as one of the most efficient degraders of PAHs among the litter-decomposing fungi, with reductions of up to 70%, 86% and 84% of benzo(a)anthracene, benzo(a)pyrene, and dibenzo(a,h)anthracene respectively (Steffen et al, 2007). The garden giant also remediates the soil by consuming the harmful bacteria that hinders plant …show more content…
Bioremediators need to be able to grow in order to remediate the soil of pollutants. The purpose of this research is to determine whether the presence of Stropharia rugoso-annulata in the soil will support and accelerate the growth of ryegrass in a mutualistic symbiotic relationship. If the growth of the ryegrass is accelerated and supported, the combination of the two bioremediators could potentially accelerate the degradation of PAHs in the soil. Techniques such as soil washing, soil flushing, vitrification, etc., exist to remediate contaminated soil. Although, these techniques are effective, they also disturb the natural environment to some degree. Bioremediation is often accomplished in situ resulting in minimal environmental disturbance. This study is being performed because healthy soil is a limited resource that needs to be preserved and replenished. The state of soil can impact the health of humans, animals, and ecosystems, therefore, it’s important to be able to monitor and control the pollutants in
This scholarly article gives an in-depth overview of the practice of monitoring the effects of genetically modified organisms on the environment. A spanning look at the types of soil organisms best suited for study in relation to GMOs is provided as well as known negative effects on soil organisms. Studying soil structures and organisms provides researchers with information that can be used to determine whether or not GMOs interact with the environment differently than non-GMOs.
Our class has concluded that the conodoguinet creek is not polluted. If we test the Conodoguinet Creek for signs of pollution, then the creek will be polluted. That was my hypothesis for the creek, but it was wrong. There are many creatures that are pollution sensitive, which means they can’t survive in pollution. We found many of these creatures in the stream. Also, we have tested the creek for pollutants and other chemicals. Lastly, acid rain is a problem, so we tested the rocks for neutralizing acid. Here are some reasons why we think the creek is not polluted.
Silver Creek Wetland Complex is a rare coastal wetland found along the eastern side of the Nottawasaga Bay Shoreline. It falls within the town boundary of the Town of Collingwood, which was formally a part of the Town of Blue Mountains. Because the area is a part of the greater Silver Creek Watershed, the marshy land is classified as a Schedule B Category 1 land under Environmental Protection as per the Official Plan of the Town of Collingwood. Blue Mountain Trust Watershed Practice monitors the watershed and the significant wetland is protected and maintained by Nottawasaga Valley Conservation Authority. The 2700 Ha watershed flows through the “Lake of Clouds” by Castle Glen, down the Niagara Escarpment, where the 160 Ha complex at the
Through our research we aimed to determine if there were any differences in water quality of both the north and south forks of Strawberry Creek. As time progresses and the environment changes it is important to keep track of how certain species are being impacted by these features, and how they cope with change. We hypothesized that due to the lack of pollution, the south fork will promote a greater diversity of macroinvertebrates. This was due to the fact that there was less runoff and trash that could be introduced to the water in the south fork, than there was in the north fork. We gathered data by analyzing the different organisms living in both forks. We collected a total of fifty vials composed of five organisms from each fork, and inspected them under microscopic view. After gathering data and identifying the different kinds of organisms living in the different forks we assessed whether the organisms from the samples could live in high or low resolution water. We also took a t-test to assess the probability of these differences being due to relevant factors or by chance. Our major findings suggest that organisms in the south fork showed a higher demand to living in cleaner water indicating that our hypothesis was correct.
A site called Coobool Creek on the Wakool River, located between Swan Hill and Deniliquin in the Murray River Valley was where G. M. Black accumulated 126 skulls from the suface area near Doherty’s Hut at the Coobool Crossing in 1950 and they were studied by Brown. The 126 crania has been returned to the Aborigines for a reburial. The collection was named the Murray Black collection after G. M. Black who found it and the location in which in was found.
The experiment we conducted was to see if the conodoguinet creek was polluted. We had three different experiments and each experiment showed that there was little to no pollution. The results we have will help notify the public and the health department if the water needs to be treated or not. We had the correct materials and background knowledge to complete this task.
The Conodoguinet Creek is a creek that runs 90 miles long from Carlisle to the Susquehanna River. The Susquehanna River is located in West Fairview. Now the question is, is the Conodoguinet Creek polluted? Pollution is caused by smoke in the air from big metal companies and fertilizers from farmers. Acid rain takes that smoke and fertilizers and rains into the ground and into waterways. That pollution can kill the organisms living in that waterway. My hypothesis is that the Conodoguinet Creek will not be polluted. Some things that will tell us if it is polluted or not is tests, scales, rocks, macroinvertebrates, and the velocity of the water. Is this acid damaging the Conodoguinet Creek?
Is the Conodoguinet creek polluted? I thought it was, but multiple tests from my peers and I proved my hypothesis wrong. To prove our hypotheses, my peers and I did multiple tests of the organisms living in the creek. We also tested the water quality. You may be wondering, “ How does this apply to me?” “ Why should I care?”, the fact is that the Conodoguinet runs through 100 miles of Pennsylvania. It runs through farms, towns, communities, and maybe even your backyard. So, making sure we protect it should concern all of us.
The Silver Bow Creek watershed in southwest Montana encompasses approximately 474 square miles and forms a portion of the headwaters of the Clark Fork River and ultimately, the Columbia River (Montana Natural Resource Damage Program, 2009). The site covers about 26 miles of stream and stream side habitat. Silver Bow Creek was used as a conduit for mining, smelting, industrial and municipal wastes for more than a hundred years (Weitz, Luxenberg). Rather large amounts of mine tailings deposits are found along the creek. These deposits contain elevated levels of metals and have been dispersed over the entire flood plain (Weitz, Luxenberg).
Although it will take a lot of time and effort to rectify the conditions at Newtown Creek, the variety in the recommendations from all the groups shows how many options are available to go about it. Some of the ideas need some more foresight in accounting for all three pillars. For example, it is not always a good idea to focus too much on environmental needs if the tradeoffs put social needs at too high of a risk. Even so, each suggestion has its own merit, especially when you use them together. By implementing multiple ideas you are tackling more then one issue/pillar at a time. Therefore, the overall outcome is better then limiting the benefits to a specific area of mediation. As Gestalt’s Theory in psychology states, “the whole is greater then the sum of the parts.” To have a successful whole you must have numerous inter-reliant components with different levels of priority depending on effectiveness, cost, social impact, and time frame.
On October 7, 2015 the orange team from East pennsboro middle school conducted extensive testing regarding whether or not the Conodoguinet creek is polluted. The team tested for, number of crustacean, macroinvertebrates, alkalinity , velocity,and eutrophication in the water. The findings can dismiss the assumption that the Conodoguinet creek is polluted. Also the findings can shed light about how clean the creek really is.
I believe that Conodoguinet creek is polluted, but only very slightly. In 3 different experiments, my group tested the quality of the water. Below are the results.
Superfund sites are located all across the United States and its territories. These sites have been deemed the worst of the worst in terms of environmental damage; they pose a threat to human health and the environment, prior to their remediation. Superfund sites are usually a result of several years of contamination; however, there are some instances when they are one-time accidents. United States Environmental Protection Agency (EPA) is in charge of Superfund, which is the common term for Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and the enforcement of this law in the United
The microbial organisms living in Peatlands, they love carbon; and they play a major role in “global carbon cycling”; therefore, peatlands are called “carbon reservoir.” Peatland microbes work well in the cool temperature, but the global temperature is increasing because of human activities such as farming, burning of fuel and disposing of industrial gas. The authors focused their study on the influences of human activities causing natural changes on the living and activities of “peatland microorganisms” especially fungi. Different types of fungi were observed on different peatland soils; moreover, statistical, analytical and graphical skills were successfully applied in this study. Finally, the article’s authors concluded that the microbial
Although they are small microorganisms have a humungous impact in the structure of soil and plant formation. Microorganisms, which include many different fungi, bacteria, and actinomycetes, are considered the architects of the soil as they have the ability to create a strong ecosystem in the soil. Microorganisms work best in communities to develop the structures for plants. For microorganisms to thrive there has to be a diverse amount of nutrients in the soil for them to feed off of. Schulz (2013) explains, “soil aggregation is of upmost importance in controlling microbial structures and functions and plant life” (pg. 1873). Microorganisms live off of different nutrients in the soil and once they digest the different
