Ddt and Malaria

Dichlorodiphenyltrichloroethane, better known as DDT is a notorious organochlorine pesticide that is created by the reaction of chloral with chlorobenzene in combination with sulfuric acid(Britannica p.1). It was first used as an insecticide in 1939 by Hermann Muller in Switzerland. DDT works as an insecticideby acting on the nervous system to generate the same neural impulse over and over causing body tremors and eventually death. DDT is an extremely stable chemical compound containing C14H9Cl5 which leads to some significant resistance issues when used as a pesticide. The most problematic property of DDT is its high fat solubility and extremely low water solubility meaning that it has a tendency to stick around in the environment for longer than we want since it is readily taken up in the bodies of nearby mammals.

During the heightened economic and technological growth that comes with every war the world fell in love with the very first man-made insecticide called dichloro-diphenyl-trichloroethane which is more commonly referred to as DDT. It was first created in 1874 by a German chemist but it was not used as a pesticide until 1939, the start of WWII. Many soldiers during

Many animals kill countless numbers of humans every second, minutes, and hours. The mosquito is among those predators, and it causes the most morbidity and mortality among humans compared to any other animal or insect. Mosquitoes are notoriously known for causing malaria worldwide. Malaria is a disabling illness which can result in mobility and mortality. People infected with the disease become weak over a period of time. This reduces their productivity level; thus it makes simple activities of daily living difficulty to accomplish. Some of the common symptoms of malaria resemble those of the flu. Malaria is an extreme health burden in low and middle income countries especially African countries. Moreover, the disease is mostly prevalent in sub-Saharan African countries, among pregnant women and children age 5 and younger. Over the years, scientists have discovered and developed several methods to control the spread of malaria. One of the most controversial control methods for malaria is DDT. DDT is short for dichlorodiphenyltrichloroethane; this method come in the form of a pesticide or insecticide. It is used to kill pest and insects specifically mosquitoes. “DDT is used in indoor spraying for control of vectors of malaria and visceral leishmaniasis” (Van den Berg, 2009). Scientists have realized that the pesticide could be effective at preventive malaria by reducing the amount of mosquitoes in the environment. Despite this, concerns about the effectiveness and safety of

Throughout his essay, Suzuki supports his arguments with specific examples. To justify his reasoning, the author uses the case of DDT, otherwise known as dichlorodiphenyltrichloroethane. This chemical compound is used as an insecticide to eliminate the population of malaria-carrying mosquitoes, which it did effectively, and saved millions of lives. Unfortunately, due to unforeseen circumstances, complications arose, which led to an increase in chemicals and caused a domino effect of

Dichlorodiphenyltrichloroethane (DDT) has had a huge impact on the fight against malaria, helping to ensure the control or eradication of malaria in many countries around the world in the mid-twentieth century. However, since its peak in the 1960s, succeeded by environmental and health concerns about the usage of the insecticide, more and more countries have been banning the use of DDT.

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

”On those visits, I feel not only the spirit of the local people…and the seasonal change.”(345).Nowadays seasonal variation in industrial societies is minimized by importing many products that mature in specific seasons from different parts of the world. Technologies however, are impacting on our lives. “DDT would exert incredible selective pressure for mutations that would confer resistance” (347), it killed malaria-carrying mosquitoes but in few years large numbers of mosquitoes will return. It also has ecological damage the compound is ingested by many organisms, become concentrated up the food chain in a process called biomagnification. It causes heavy bird mortality.

DDT is a chemical that is widely known for is properties as an insecticide. When humans discovered this “wonder product” the whole country was on fire! The one company that made the most money was Montrose Chemical Corporation. From 1942 - 1971, when DDT was banned, the MCC pumped out DDT tons at a time. However, the bigshots were faced with a problem. Where do you dump all the leftover byproduct? Hey, why not the ocean! When DDT byproduct, DDE, was dumped into the ocean, fish and other seafood had it leached into them. This meant the bald eagles’ main food source was contaminated. When the bald eagles ingested their main source of food, the DDE became very concentrated in them. When bald eagles attempted to lay eggs, barely any would hatch! The DDE caused their eggs to be porous, and the eggs fail to hatch. This meant the bald eagles’ total extinction on the Channel Islands by the 1950’s.

Background - Malaria is a water borne disease. It is spread by a parasite-carrying mosquito. It kills many people and reduces a country 's capacity to develop. There are different strategies to combat malaria. Around half the population is at risk of malaria and this disease is active in 106 counties across Africa, Asian and the Americas (see source 3). the global annual mortality from malaria is between 1.5 - 3 million deaths, or between 4000 and 8000 each day. Developing countries are most vulnerable to Malaria and as shown on source 2 Malaria has been spread across many various other countries including in Europe, but these countries have eradicated Malaria.

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.

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

While DDT is good for killing bugs, it is also really good at breaking down our foods. One study by the President's Cancer Panel showed that girls exposed to DDT before puberty are five times more likely to develop breast cancer in middle age. Really the only good thing that comes from DDT is that it’s a possible solution for malaria control, but even then it’s rare that DDT is the most effective option. The dangers and harmful effects of DDT are too dangerous and society as a whole needs to stop using

DDT (dichloro-diphenyl-trichloro-ethane) was one of the most commonly used pesticides during the mid-1900's. This chemical was found to be effective in killing mosquitoes, thus stopping malaria epidemics, and was also useful against farm pests. However, mosquitoes often became resistant to this unnatural chemical after a generation or so of selective breeding. In fact, this pesticide did much more than simply getting rid of the insects pestering man. The most deadly feature of DDT was its ability to move through the food chain at a deadly pace.

The animals that DDT is most toxic to are fish. It is so harmful to fish that it is extremely difficult to study. In actuality, DDT grows less toxic within hotter water temperatures, which means that tropical fish are not as loomed over by the dangerous shadow of DDT as much as other fish. Sadly, since it is insoluble to water it wreaks havoc on the fish population. The insecticide manages to find its way to a body of water by being carried by runoff. It rarely can find its way into groundwater, and usually stays on the top of the soil. With that being said, our next subject is approached: its

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
