Summary
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.

Hazard identification

Malathion is a strong insecticide used primarily to control insects on crops. Water, sunlight and soil brake down Malathion when it is exposed to these elements. If you are in the vicinity of the area sprayed, this is where you will get the exposure of Malathion. Usually the risk comes from Malathion in the air or on the surface of something you may touch. The brain and the nervous system are affected when exposed to Malathion. You may have trouble breathing or headaches, chest pains, vomiting, dizziness and even death. However if you seek medical attention immediately typically there are no long term affects. What happens if you do not know that you have been infected? Once in the air Malathion will get on cars, homes, furniture and shoes carrying it into homes and around our children and infants. Malathion can be inhaled or digested if it gets into our water. There are safety precautions but I do not believe that all residents of Wilhelmville City will be prepared to take or have enough knowledge to do so. Malathion can also harm our livestock in our county and surrounding counties. If our cattle ingest it and we sell the cattle to slaughter, the meat can be ingested into humans. Dose-response

“At very high doses, Malathion exposure can lead to death. Acute dermal and ocular exposure can cause slight

    1. Carlson classifies modern insecticides into two groups of chemicals. The first group, represented by DDT, is known as the “chlorinated hydrocarbons” and the other group, represented by Malathion and parathion, consists of the organic phosphorus insecticides. Although both are organic, the organic phosphorous insecticides are more poisonous than the chlorinated hydrocarbons and have the ability to destroy enzymes.…

    The current cycle of global warming is changing the rhythms of climate that all living things have come to rely upon. What will we do to slow this warming? How will we cope with the changes we 've already set into motion? While we struggle to figure it all out, the face of the Earth as we know it coasts, forests, farms, and snowcapped mountains hangs in the balance. Mitigation means lessening the negative effects of something, usually something that cannot be entirely prevented. Thus a pollution mitigation plan would be a plan to reduce the effects of pollution. My topic I chose too discuss is Global Warming based on saving our water supply.…

    First synthesized in 1874, DDT's insecticidal properties were not discovered until 1939. In the second half of World War II, it was used with great effect among both military and civilian populations to control mosquitoes spreading malaria and lice transmitting typhus, resulting in dramatic reductions in the incidence of both diseases. The Swiss chemist Hermann Müller of Geigy Pharmaceutical was awarded the Nobel Prize in Physiology or Medicine in 1948 "for his discovery of the high efficiency of DDT as a contact poison against several arthropods. After the war, DDT was made available for use as an agricultural insecticide, and soon its production and use skyrocketed.…

    Pesticide Penetration

    The rapid absorption of pesticides through this specific route increases the hazard of respiratory exposure. The greatest potential for poisoning via respiratory exposure is with vapors and extremely fine particles of the spray solution. Pesticide exposure is usually low when dilute sprays are applied with common conventional spraying equipment because larger droplet sizes are produced. By contrast, when low volume equipment is used to apply concentrated material, the potential for a respiratory exposure is increased because smaller droplets are being produced. Pesticide application in confined areas (e.g. greenhouses) also contributes to increased potential for exposure through inhalation. Respirators and gas masks can provide protection from respiratory exposure. Eyes are particularly sensitive to absorption, and therefore any contact of pesticides with the eye presents an immediate threat of injury, blindness, or even death. Eye protection is always a prerequisite when measuring or mixing concentrated and toxic pesticides. Proper protection of the eyes also should be used when there is a chance of exposure to the diluted spray or dusts that may drift into the eyes. Pesticides in a granular formulation may also present a hazard to the eyes due to the size and weight of the individual particles. If applied with power equipment, particles may bounce off vegetation and cause significant eye injury as well as poisoning to an applicator if struck in sensitive body areas (i.e. the eye). Therefore, protective goggles should be used whenever there is possibility of pesticides coming into contact with the…

    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…

    One of the most prevalent and controversial insecticides used in America was DDT, commonly used in America’s heartland until it was banned in the 1970s. It was used to decrease the widespread infection from malaria, typhus, and other insect-borne human disease but eventually caused worry and panic among American citizens with the publishing of Rachel Carson’s Silent Spring (EPA). On one hand, DDT causes a variety of environmental problems like the weakening of bird eggshells, a long appearance in soil, and can seep into groundwater, affecting both humans, animals, and ecosystems alike. On the other hand, it is effective in killing of the deadly diseases that still kill hundreds in Third-World countries today. I believe that, regardless of the negative effects of DDT, it should be used to actively combat the life-threatening diseases that plague some countries today. However, it…

    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 no long term affects; while low level exposure has few, or no health problems. Since Malathion is an insecticide it needs to be spayed at dusk to reduce the harm factor of the animals, and other insects. (http://www.atsdr.cdc.gov)…

    Secondly, insecticide create problems of their own. For example, many species of insects have become tolerant, either resistant or immune, especially to DDT, which had been the most broadly effective insecticide. Also, biologist have found that the careless or excessive uses of insecticide destroys many beneficial insects, birds, and small mammals. In addition, some insecticides, especially DDT, tend to persist in soil and water and can eventually accumulate in the body tissue of fish, wildlife, and humans. DDt also tends to combine with other chemicals in the soil, producing new toxic compounds that are more harmful than DDT alone.…

    Human/Health Effect: Pesticides that have this lethal quality towards insects, animals ,and this animal diseases lead to health problems towards humans as well. The application of pesticides is often not very precise, and unintended exposures occur to other organism in the general area where pesticides are applied. Young and developing organisms like children, are particularly vulnerable to the harmful effects of pesticides; such that even very low levels of exposure during development may have adverse health effect. . Also, over exposure to these pesticides lead to skin problems,…
