Malathion Risk Assessment Essay example

A positive consequence of DDT is its effectiveness, even in the face of pesticide resistance in the anopheles mosquito. The eradication of malaria in the United States and the health of US Soldiers while fighting in World War II can be greatly credited to the use of DDT

In the mid-20th century, farmers used a toxic insecticide named parathion in an attempt to control pests detrimental to their crops. Rachel Carson was a biologist who wrote pamphlets (Lear) on conservation and natural resources designed to inform people on the beauty of the living world. In an excerpt from her 1962 work Silent Spring, Carson calls upon the public to take action against the use of parathion by highlighting its catastrophic nature and vilifying the agricultural community for their negligence.

Furthermore, the preceding statement supports Carson’s intention to present an informative, persuasive, and logical point of view without shocking or confusing the reader. Carson presents the problem calmly in the opening paragraph and states her claim as a practical approach to stop or decrease the amount of the spraying of DDT pesticides in combined efforts to stop the super races of insects like mosquitoes for example from becoming immune. Including this support for her thesis Carson argues mosquitoes becoming immune to the man-made vaccines presently available would inarguably have serious, detrimental and adverse negative impacts upon the effectiveness of the

Although I feel that malathion, when correctly regulated, is perfectly safe for humans, I do not feel that it’s worth the impact it will have on the environment. Being highly toxic to important insects and fish will negatively affect the surrounding ecosystem. Once we began to deplete that, then there definitely won’t be any mosquitos left to worry

Malathion has been introduced to our City Council here in Wilhelmville. We as a community are looking for a pesticide to kill these insects destroying our crops, however in reviewing information found and presented to us and our council we have a split decision. Below is what we have been presented with by concerned citizens of the community. When presenting this information to the members of the council will assist me and others in our decision whether this is the pesticide that we need to use here in our community.

After considering my above feelings and thoughts I realised that by being aware of the time I spent on the risk assessment, I was able to keep it as necessary and as concise as I had hoped for. Previously I have ran out of time completing the full assessment, meaning that the ending of the assessment is typically missed off. According to Westbrook et al (2007) five or ten minutes is required at the end of treatment to conclude and set up a homework task. Although at the time I was feeling anxious and nervous; attempting to keep track of the time allowed me to achieve the assessment in the time I had allocated myself.

In my opinion, I think that the city of Genericville should refrain from using the chemical Malathion on their wetlands to control the mosquito population. The risk of fatalities is higher due to exposure than infection from West Nile Virus. The risk of harming other wildlife in the process must also be taken into account. Natural predators to the mosquitos like birds and bats should be protected and allowed to thrive to aid in the prevention. Due to the lack of information and research on long term and environmental effects of its use, I vote to not use the chemical until its risks are more identifiable. For now, the risks outweigh the benefits.

Parathions are extremely toxic compounds, which are formed by the elements phosphorous and sulfur, and are commonly used as agricultural insecticide. According to the Fish and Wildlife Service, areas exposed to parathions result in potential peril concerning domestic animals, wildlife and humans. Noted biologist, Rachel Carson, argues against the farmers’ use of parathion to kill blackbirds because they are also harming the environments of wildlife and humans. Carson applies offensive diction, imagery of the disaster created by parathions and pathos to evoke the audiences’ sorrow. She addresses her concerns to an audience that values nature in order to terminate the farmers’ utilization of parathions and conserve biological life.

This means there will be a check to see what health problems are caused bymalathion. We would check the toxicokinetics, to see how the body absorbs and processesmalathion and the toxicodynamics to focus on if there are any effects from the chemicals on thehuman body. This would be done by a dose-response assessment, to see what the healthproblems are at different amounts of exposure. Doing a exposure assessment we could see howmuch of the malathion people are exposed to for the months of June, July, and August. With thiswe can also see how many people will be exposed. Then checking the risk characterization to seewhat the risk is of the certain health problems to the exposed population.Malathion is an organophosphate insecticide it was first registered for use by the USDAin 1956. It is now regulated by the EPA. It is used to control a broad assortment or insects bothagriculturally and residentially. Malathion is registered for use on crops, food, and feed.Malathion is toxic via skin contact, inhalation and through ingestion. It works by overstimulating the nervous system and ending stimulation of the neurons. Malathion has a very loworal toxicity. With lower toxicity in males than

Poor air quality and breathing in the dry residues from toxigenic organisms can cause multiple health concerns. This material has the potential to create havoc in many ways.

First off DDT has the ability to kill insects that carry diseases such as malaria. There is

There have been many attempts at preventing malaria, none of which have been very successful. These have usually involved protecting human beings from mosquitoes, the dreaded carriers

Each flowchart step is placed in the “Lane” for the group responsible for completing the task (Marketing, Sales, HR, etc.).

Bacillus thuringiensis is a spore forming bacterium that produces crystals protein which are toxic to many species of insects. Therefore it is used a natural pesticide. It is naturally occurring throughout the world and its usage is very common. There are thousands of different Bt strains. The kurstaki strain being the most common kills only leaf- and needle-feeding caterpillars. In the last ten years, Bt strains have been mostly used to control the abundance of flies, mosquitoes, black flies, amongst others. When it comes to Bt strains, the target is very specific. The strains for mosquitoes will only target them and not affect other insects. Even though Bt is used in aerial spraying programs and transgenic crops its main usage in organic farming.

Risk management is the term applied to a logical and systematic method of establishing the context, identifying, analyzing, evaluating, treating, monitoring and communicating risks associated with any activity, function or process in a way that will enable organizations to minimize losses and maximize opportunities. (Lecture notes)Risk Management is also described as 'all the things you need to do to make the future sufficiently certain'. (The NZ Society for Risk Management, 2001)
