Risk Assessment of Malathion
Currently before the Genericville city council is a proposed pesticide application program to reduce the mosquito population. The current pesticide of choice for this is Malathion. While there are many different viewpoints on the effects of the pesticide Malathion, it is my decision as a city council member to vote for the usage of Malathion as part of the pesticide application program. Included in my vote is the condition that extensive educational efforts are given to the public, notice of when and where the pesticide will be applied, and its potential risk and hazards be given to the citizens of Genericville. After doing extensive research and a risk assessment of Malathion, I believe that the benefits outweigh the risk in using this pesticide. First, I will give a little background on the mosquito. Mosquitoes are two-winged flying insects that need blood to fertilize their eggs. There are over 3000 different species of mosquitoes in the world. In the United States, there are 150 different species of mosquitoes (Crans, 2004). Female and male mosquitoes have an average lifespan of two weeks and feed on plants. It is the female mosquito that bites and feeds off humans, birds, and other animals blood to help fertilize their eggs. Because of this, female mosquitoes can spread diseases such as malaria, yellow fever, and West Nile virus (CDC, 2010). According to the American Mosquito Control Association (2010) there are “at least 43 species of mosquitoes have been found infected with the West Nile virus in the United States.”
The Centers for Disease Control (CDC) website (2010) stated that as of October 26, 2010, there were 832 cases of WNV and 34 fatalities in the United States excluding Alaska and Hawaii. While there have been no incidents of WNV in Genericville within the last year, projections for WNV in Genericville are estimated to be about 50 cases with two fatalities. The reasons for

    Leukemia is the malignant disorder of white blood cells in which the cells become abnormal and divide without control or order. Hematopoietic stem cells, also known as hemacytoblasts, are found in bone marrow and are the precursor to erythrocytes (red blood cells), leukocytes (white blood cells) and thrombocytes (platelets). Leukemia is caused by the mutation of the bone marrow pluripotent or most primitive hematopoietic stem cells (Caldwell, 2007). The mutations during hematopoiesis causes uncontrolled proliferation of stem cells resulting in overcrowding of bone marrow and decreased production and function of normal hematopoietic cells (Huether, 2012). The leukemic stem cells will then enter the blood stream affecting other organs such as the liver, spleen, lymphnodes, and under certain circumstances the central nervous system. The mutant clone may demonstrate unique morphologic, cytogenic, and immunophenotypic features that can be used to classify the particular type of leukemia (Caldwell, 2007). Leukemia can be fatal if left untreated because of the inhibited ability to produce and provide normal red blood cells, white blood cells, and plates to maintain homeostatic mechanisms.…

    Mosquitos are the deadliest vector on Earth, meaning that they carry many different types of viruses. In order to control the rapid spreading of these viruses through mosquitos, different groups of people started to use different pesticides to kill the insects carrying the viruses since it mutates too quickly in order to create a vaccine for many, such as Malaria or The West Nile Virus. One benefit of using pesticides to kill the mosquitos is that it helps to bring down the spreading of viruses since the vector is destroyed. This allows crops to grow quickly without insects and the viruses they carry from killing of the crops. The increase in the amount of crops causes the prices of the crops to come down, both stimulating the economy. A second benefit is that the use of pesticides creates jobs, which also stimulates the economy. One thing that is bad about the use of pesticides is that people can ingest the pesticides and it could cause illness and in some cases, death. Another bad thing about the use of pesticides is that pesticides can destroy the environment by killing more things than they are supposed to, interfering with the food chain leading to the death of other species. I do not support the use of pesticides because they lead to the death of humans and other species which I do not believe is an acceptable activity if people are dying and the environment is being destroyed by the use of them. There are good things about the use of pesticides, but there are also many drawbacks to using it.…

    Ddt Pros And Cons

    In order to solve this question, we would have to know the pros and cons of DDT and its effects on society. DDT is the cheapest and most effective way of stopping malaria, but even the mosquitoes will develop a resistance to DDT. Since this chemical lasts twice as long as other pesticides, it is better to continue using DDT, because there is no real reason not to use it. On the other hand, insects will start to develop a sort of resistance to this harmful chemical. “It is the ‘tough’ insects that survive chemical attack. Spraying kills of the weaklings. The only survivors are insects that have some inherent quality that allows them to escape harm” (Rachel Carson). DDT was extremely effective and useful when it was first introduced. The more…

    Ddt and Its Effects

    Dichlorodiphenyltrichloroethane otherwise known as DDT was used worldwide for agricultural and public health purposes from the 1940s until the 1970s, when concern rose for its toxic effects on us humans and wildlife, its environmental persistence and its levels in the food supply led to restrictions and prohibitions on its use. Today DDT is now only used for vector control mainly in Africa and Asia. DDT is a potent insecticide used for Indoor Residual Spraying (IRS), being sprayed inside people’s homes and in buildings for malarial control. IRS with DDT being used as its main insecticide has exposed humans to high levels of DDT and this high exposure has been linked to serious health affects for humans, these health affects even include some cancers. Due to DDT’s toxic effects not only on our environment but on humans themselves, DDT should be banned for use against malarial control because of the high levels humans are now exposed to causing great health risks.…

    Malathion shows little cause of increased likelihood to adverse health effects. Compared to other organophosphate insecticides Malathion has relatively low toxicity to humans, other mammals, and birds, which is why Malathion is the preferred method used to kill mosquitoes and prevent West Nile Virus (Agency for Toxic Substances & Disease Registry, 2007). All the residents will be informed of the dates of application as well as the rate of exposure they will encounter should they go into the areas of direct application. Residents will also be informed to try to stay out of the areas of application for at least a week and to not touch anything that may have Malathion applied to it.…
