Hazard identification
Malathion is an insecticide that is used primarily on crops to control insects. Malathion brakes down quickly when exposed to the elements like soil, water, and sunlight. Normally people are not exposed to this insecticide unless they are in the vicinity of the area that is being sprayed. Then the risk will be the spray that is in the air, or on surfaces that have been touched. (http://www.atsdr.cdc.gov)
Malathion affects how the brain and the nervous system work and exposure to excessive amounts can cause difficulty breathing, tightness of chest, cramps, vomiting, diarrhea, blurred vision, headaches, dizziness, los of consciousness, and death. However if treatment is administered quickly Malathion has

Maximum amount would be 8 ounces per acre plus the delivery agent that it is delivered to the mosquitoes in. The river and surrounding marshlands can be sprayed once and then sprayed as needed to eliminate the problem areas that surface. (http://www.atsdr.cdc.gov) The economic aspects of spraying Malathion for mosquito control would be; that in an aerial application it is very expensive with the use of airplanes, or the helicopters for the delivery. This will also be an annual expense with the mosquitoes returning another year.

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
Some of the risks are getting cancer from the inhaling Malathion once it is airborne. You also have the factor of it getting on our children, especially out toddlers. We have the largest corn field in the county right behind the middle school. What about that? Tests have shown that Malathion case cause Asthma, trouble breathing and shortness of breath. I believe it is too much of a danger for our families and the members of this community. We must find another pesticide to use for our crops.
DDT has been used since WW2 as an insecticide to control the outbreak of malaria and typhus among troops and civilians. This is because malaria is spread by mosquitos and DDT was considered to be a powerful in eliminating these populations, thus decreasing the infection rate for malaria. Since it was first discovered as an insecticide, worldwide it was used in very large amounts because nobody knew any better and it was considered to be revolutionary. It wasn’t until 1962, when biologist Rachel Carson first outlined the potential harm DDT has on the environment, believing it caused cancer in humans and harmed bird wildlife. This led to the United Stated ban of DDT use in 1972, and later, a worldwide ban under the Stockholm
When phenylalanine builds up it affects brain functions and the central nervous system. Some symptoms include: skin problems, neurological impairment, seizures, development delays and mental retardation.
DDT is a very controversial product… but why? DDT was a pesticide used in the 1950s and it was very effective at killing mosquitoes. This was good because mosquitoes carry a very deadly disease called malaria. But soon the government banned its use in the USA. It supposedly has been decreasing the populations of bald eagles. They think that it makes the eggshells thinner, so when the eagle it trying to keep the eggs warm it might break the eggs on accident. Many people are happy about this ban and others are not. Some researchers feel that evidence supports a ban on DDT while others feel that it is an over reaction to an environmental concern. DDT has been shown to help control the malaria parasite. Evidence supports the banning

In order for a pesticide to be approved for use it needs to pass a few tests. The government examines the ingredients to ensure they are within safe boundaries, they also examine which crops and where it would be applied, how much you need to use for it to be effective and how often it needs to be used and also how it must be stored and how it can be disposed of (United states environmental protection agency 2016). With all of these regulations in place, it is extremely rare if not impossible for an unsafe products to pass through
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
ScopeThe scope of this risk assessment is to determine the risks vs. benefits of sprayingMalathion to control the population of mosquitoes that inhabit and reproduce in thelakeside community. It is not intended to advise on mosquito spraying efforts for anyother portion of the Town of Hillsborough, NH, or any other community, as theinformation considered herein was considered using the demographics of the ELVDcommunity alone.2.

In the early 1940’s, a new technology emerged that was able to successfully combat crop-damaging and disease-carrying insects. A new age of synthetic chemical pesticides use arose. After their impressive success in fighting deadly insect-borne diseases during World War II, pesticides were used widely to combat insect pests for agriculture and public health. Few people challenged the benefits of the new scientific and technological products and many embraced pesticide use with enthusiasm. Despite its success, doubts about pesticide use began to appear a decade later in the 1950’s, when the government began a vigorous pesticide campaign across the country against insect pests. Scientists began reporting heavy losses of avian and
To understand pesticides, we must look at the facts about them. According to the EPA, pesticides are chemicals specifically designed and sold to prevent, destroy, or repel pests from garden, greenhouses, fields, and orchards (Learn About Chemicals Around Your House). Charlotte Gerber’s article, How Do Pesticides Kill Bugs, explained that pesticides targets insects and kills them by attacking the nervous system and then when the muscles are over-stimulated, this will lead to paralysis and death. The effect of the organophosphates that cause that in pesticides was discovered in the 1930's during World War II. They were used in the creation of nerve gas, which was used in chemical warfare. When used in lethal dosages for humans, organophosphates cause extreme excitability, convulsions, paralysis and in most cases, death (Gerber). According to Effects of Pesticides on Human Health, The World Health Organization estimates that there are 3 million cases of pesticide poisoning each year and up to 220,000 deaths, primarily in developing countries (Lah and Glibert 2011). Children, and any other young and developing organisms, are particularly vulnerable to the harmful effects of pesticides. Even very low levels of exposure during development may have adverse health effects. Exposure can even lead to neurological health effects such as memory loss, loss of
Another disputed environmental issue is the use of DDT and if it should be banned worldwide. DDT has been a cheap and effective pesticide used against mosquitos carrying malaria, saving millions of lives. However, this pesticide has now been included in the “dirty dozen” due to its environmental effects, but about 25 countries continue to use the toxin (Easton, 281). Anne Platt McGinn provides the stronger argument stating DDT is less effective than previously and it should be banned or reserved for emergency use due to the environmental effects. On the other hand, Professor Donald R. Roberts ineffectively argues the environmental hazards have been misrepresented and the threat of malaria is more important, making DDT necessary to save lives.
“The United States has more than 330 million acres of agricultural land that produce an abundant supply of food and other products. American agriculture is noted worldwide for its high productivity, quality, and efficiency in delivering goods to the consumer. When improperly managed, however, activities from working farms and ranches can affect water quality” (EPA).
It would appear that DDT would be the obvious choice to prevent cases of malaria in developing nations and all over the world. However, DDT is not without its potential hazards. DDT was used as a pesticide in the United States until it was banned in 1972. First employed as an insecticide in 1939, the white powder would kill massive amounts of mosquito larvae. Paul Müller actually won the Nobel Prize for first using the chemical on insects. The pesticide was used throughout the United States to combat more kinds of insect-pests such as gypsy moths. It was not
In the best case scenario, you can expect a number of nasty physical side effects. Some of the more common ones include diarrhea, headaches, nausea, muscle cramps, high blood pressure, and restlessness.
