Ecology and Wildlife Risk Evaluation Analysis

ENV/420

This analysis of case studies from Los Alamos National Laboratory, and the case study to predict the effects of pesticides on aquatic systems and the waterfowl that uses them. Comparing the two processes of these case studies, along with analysis of the assessments. Describing the case study on the effects of pesticides in aquatic ecosystem, the risk assessment correlated to observed field studies and evaluate the importance of this type of correlation in general for all risk assessment efforts. Breaking down the ecological and social values in the assessments. Try to establish a value for the components in each case and how the risk assessment was determined.

The process of defining ecological value in Los Alamos National Laboratory (LANL) from section 19.5 took an approach to take a structured process to break down the value of the different species that are located at LANL. This was done to ensure that all relevant valued resources was used to come up with the endpoints, and provide the proper documentation to form a structured that was based on the resources. This process known as the general assessment endpoints (GAE) helped eliminate data that was not needed and helped provide the means of having data that was needed to follow through with the assessment, along with the values for each potential ecosystem that is based on potential exposure to the environmental stressors.

The comparison of the two assessments take a different approach as the endpoints are staggering in the LANL case as the amount of species possess many possibilities to establish the relevant value of the endpoints that are needed to complete the assessment. By utilizing just the values that the stakeholders suggested in case study Los Alamos National Laboratory,

What impact do you think the presence of multiple types of hazardous waste will have on the ability of investigators to establish a cause-and-effect relationship between specific chemicals and adverse (negative) biological changes in Tidal Bay? A number of measurements were used to quantify contaminant impact on the ecosystem. These include several bioassay species, benthic community composition, bioaccumulation, and fish histopathology.…

    Pesticides are toxic and go through many different testings and procedures before they are put on the shelf in various industries. One general method that is used to asses toxicity of pesticides before released for sale is the LD50 (Lethal Dose 50) method. This method is conducted by calculating the most accurate dose of toxin that will kill animals 50% of the time. Before determining an accurate LD50 of a chemical however, a range finding analysis of the chemical will be performed in order to calculate the most accurate LD50. Undergoing this procedure includes using a wide-spread range of concentrations which are mostly preformed at log dose intervals. (H.P. Rang, M.M. Dale, J.M. Ritter and R.J. Flower, 2007).…

    The Department of the Interior protects America’s natural resources while honoring our various heritage, cultures, and tribal communities as well as supplies the energy of the future. The primary focus is within the Fish and Wildlife Service of the Federal Government. The existence of wildlife and plants is constantly threatened as a direct result of humanity. Global Warming is finally receiving acknowledgement necessary to make a difference in the wasteful and destructive routines of human expansion. Artic wildlife is experiencing the most difficulties as the surrounding glaciers are all melting. Our primary focus is on polar bears as they rely on masses of ice to rest after hunting for food. With the emergence of warmer climate, the areas of ice are diminishing leaving polar bears swimming for even longer until they drown from exhaustion. A federal regulation was passed in May of 2008 to protect the polar bear species from extinction by adding them to the endangered list. This should be a wake-up call to every individual living on the planet Earth as it is time to take responsibility for our actions and start making serious changes. Continued decrease of sea ice levels is expected in the future which affects the entire span of polar bears which reclassifies their status as threatened and endangered.…

    Pesticides are widely used in modern agriculture in order to increase crop yields by inhibiting predation and competition (Berkley). Large corporations have flourished under the demand for more affective pesticides and have in result developed stronger and more effective pesticides. In their race for wealth and influence is it possible that the greater good of man and an outlook for a sustainable future was overlooked? Could these companies have developed products that, used abusively will wreak havoc on natural ecosystems? Through this paper different aspects of pesticides, with a focus on Monsanto’s Roundup® will be assessed on their effects on the environment. Impact will be weighed and a conclusion will be drawn on the use of pesticides such as Monsanto’s Roundup’s overall negative effect in…

    In the 19th century the industrial revolution began with the introduction of steam engines, telegraph machines, and assembly lines, vastly improving the economic standing in America. Transportation modes increased, electricity was mobilized, and industrial mechanisms were heightened. With advancements in technology and transportation beginning in the 1700s, ecological contamination also elevated, creating risks to human health and environmental conditions. An increased awareness of toxins either purposely ingested or found in the environment, and the dose-response relationship that had already been established was studied more thoroughly to gain a better understanding in the role it played in human risk. The expansion of knowledge was vital to the decision-making relationship regarding advancements in risk assessment (Bernstein, 1996). The industrial revolution allowed elevated apprehension to ecological contamination and risks associated with chemical pollution, unsanitary conditions to water and soil, and environmental deterioration. Waterways were no longer pristine and had become areas for industrial waste (Paustenbach, 2002). The Progressive Era raised awareness to conservation practices and initiated a variety of laws, bills, and organizations to aid in the protection of humans and ecological health. Risk assessment became an analytical enterprise that was supported by information and facts helping to justify regard to humans and the ecology. Physical, chemical, and biological stressors had proceeded to be…

    Michael Pollan writes about the three ecological consequences of synthetic fertilizers. The first consequence is the contamination of drinking water caused by synthetic fertilizers. The second consequence is the overflow of the fertilizers to the ocean and forest. The third consequence is the “dead zone” in the Gulf of Mexico created causing the death of a huge amount of living organisms. The three consequences are not anything beneficiary to earth, they are instead disasters. Similarly, Rachel Carson mentions the negative effect pesticides have brought to the environment. Carson wrote, “ …, the central problem of our age has therefore become the contamination of man’s total environment with such substances of incredible potential for harm, …”(8). She suggests to be cautious about the direct impact of pesticides on human. Both Michael Pollan and Rachel Carson are aware of the harmful effect of the human-made chemicals. Despite the fact that the two objects are completely different, they still are harmful to the well-being of all organisms living on…

    Wildlife, along with the human population is affected by environmental estrogens. Fish are affected by estrogens contained in DDT, a frequently used pesticide, and PCB’s, Polychlorinated Biphenyls. Scientific studies conducted on small animals such as frogs, produced bizarre defects such as additional extremities and the absence of eyes. (Cody 1998). Some species of frogs have also been noted to be becoming extinct because of these harmful chemicals filling the environment. A large amount of environmental estrogens exist in some of our nation’s rivers…
