When the chemical makes contact with skin, is ingested or inhaled, it can be toxic. The result is a binding of the enzyme acetylcholinesterase (AChE) in the nerve endings, a build-up of acetylcholine (ACh) neurotransmitters. This causes in an overstimulation of the nervous system. 4 AChE is found in mammals, amphibians, fish, reptiles and birds. The effect of Malathion exposure, in addition to overstimulation of the nervous system, can lead to overstimulation of glandular cells, autonomic ganglia, the central nervous system, and both smooth and skeletal muscles. Mammals and birds are able to degrade Malathion more quickly than it is oxidized. This accounts for...

...one hour at a time, twice a day, for 42 consecutive days. Subjects reported nasal and eye irritation at the highest doses, during the first few minutes of exposure. No notable effects occurred. Researchers then tested the effects associated when Malathion used as ground treatment. In an area containing 132,000 people, a total of 230 reports of pesticide-related illness were reported. 34 of these were classified as probable and 89 as possible cases.
All in all, no data has been found that Malathion causes developmental or reproductive effects in humans. Little more than minor irritations have been found in studies involving even high doses. While the potential is there for skin and neurological irritation, Malathion, if ingested, is typically metabolized and excreted within 72 hours. There is little evidence to suggest the need to worry about its use as a pesticide.

- Insecticide resistance is defined as a genetically-based decrease in susceptibility of an insect population over time, in response to long-term exposure to an insecticide. There is a shift in the genetics of a population that allows individuals within a previously susceptible population to survive. Resistant populations inherit traits that reduce their susceptibility to individual insecticide. In other words, pests develop a resistance to a chemical through natural selection: the most resistant organisms are the ones to survive and pass on their genetic traits to their offspring (Miller, 2004).Resistance develops in all agricultural insects and they resistant individuals are initially quite...

- Malathion Risk Assessment Based on surveillance and monitoring Genercville, the wetlands have become a breeding ground for mosquitoes. The proposal is to use the pesticide Malathion in order to control the problem of mosquitoes that could possibly infect the people with the West Nile Virus. The following is my analysis and evaluation of this pesticide. Malathion is an insecticide which is used in agricultural and horticultural applications to control mosquitoes and boll weevils (ATSDR 2001 West Nile Control).... [tags: Business Risk Assessment]

- The Insecticide Bacillus Thuringiensis What is this Bt toxin that is in the food we eat. Bacillus thuringiensis is an insecticide with unusual properties witch make it very useful for pest control in certain situations. Bacillus thuringiensis is a naturally occurring bacterial disease in some insects. It is very common in the soils around the world. There are many strains of Bt that can infect insects and kill them. The Bt toxin has been developed because of this unusual property. The insecticidal properties of Bt were first discovered in 1911.... [tags: Papers]

- Strategies of improving the use of insecticide treated nets amongst antenatal women in North central, Nigeria. Background The preventable and curable, but life threatening parasitic disease known as malaria have been a graven menace transnationally, with more prevalence in tropical climatic regions, such that in 2013, the World Health Organization ( WHO) reported that, about 207 million people were infected annually with the plasmodium species, with over one million deaths cases annually occurring as a result of this disease (Afolabi et al., 2009), and about 627, 000 deaths cases occurring highly among African children (World Health Organization, 2013a), such that for every 30 seconds a chil...

- I. Background The three major Detroit-based manufacturers of the American automotive industry, General Motors, Chrysler and Ford, are jointly referred to as the Big Three for distinguishing their operations from those of competitors in terms of size, sales, geography and profits. In early 2009, the Big Three found themselves covered in debts and losses as the U.S. Government handed them an initial bailout package worth $25 billion to rescue them from bankruptcy (Isidore). Through an analysis of the ethics behind government bailouts and an evaluation of arguments for and against the decision to give out such a package to the auto firms, I shall argue in this paper that, given the circumstance...

- A thorough analysis of the external forces that shaped the global automotive industry in 2009 reveals how the rivalry between established car makers set the stage for some to successfully survive the global recession while others were forced to seek Chapter 11 bankruptcy. A closer consideration of the impact of consolidation, demand and supply, fixed costs, product differentiation, and exit barriers on rivalry within the industry reveals how new entrants and weaker competitors were able to take advantage of environmental opportunities during the recession and gain profit shares....

And this past year (2009) was not different from the others; I was very excited waiting for Christmas. Especially, because I was going to spend this holiday in Mexico with my grandma, aunts, uncles and cousins, but all that emotion did not take me to a Christmas full of joy as the past years.

- Financial Crisis 2009 The United States has seen this situation before and survived; but not without change. Any solution to the current financial crisis will need to include the three players; individuals, banks, and the government. All three will also need to be held accountable. Many individuals have stepped beyond their personal means, financial institutions have acted with blatant neglect, and so far the government has in essence stood by and supervised the entire show. Capitalism is the American ideal, but unchecked and immoral capitalism leads to collapse through greed.... [tags: US Economy]
