Ddt Pros And Cons

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

In conclusion, DDT is a harmful chemical to all organisms around the world. DDT has caused disasters to humans, plants, birds, and ocean life. Thankfully, the U.S. has banned the use of DDT and has no longer put humans at risk. This chemical has done plenty of damage to our world during its time of use.

94% of the soybeans and 72% of the corn grown in the US are genetically engineered to be Roundup Ready, or able to withstand Monsantos Roundup herbicide or its generic form glyphosate. While Monsanto initially marketed Roundup as being “safer than table salt,” several studies have pointed to health risk. In 08 study in Sweden linked Roundup exposure to non-Hodgkin’s lymphoma. In 07 study in Ecuador found a higher degree of DNA damag in a population that had been aerially sprayed. DNA damage can ultimately lead to cancer or birth defects. In 03 study of tadpoles exposed to Roundup in Argentina found a higher incidence of skull, eye, and tail abnormalities. Corresponding to that study, a 09 study in Paraguay found that women exposed to Roundup

Malaria kills a huge number of people in sub-Saharan Africa every year, and DDT has some effective sustenance against the mosquitoes spreading the disease. “One in 20 African children die of malaria, and many of those who survive are brain-damaged. During the rainy season in some parts of Africa, entire villages of people lie in bed, shivering with fever, too weak to stand or eat” (Rosenberg).Authorities consider the benefits of DDT in preventing malaria are well worth the contamination. In poor areas of the tropic, they don’t have enough money to use a healthier and more effective technique to prevent malaria, DDT is a better choice as an inexpensive pesticide. Meanwhile, high temperatures in tropic areas lend to chemical pesticides break down easily. Even though they know that these chemicals are harmful to the environment, DDT had already saved a huge number of children’s lives in sub-Saharan Africa. For example, Madagascar banned using DDT and had an outbreak of malaria, leading to the death of more than 12,000 people. For them, getting rid of the threatening malaria is more important than protecting the environment. If they lose their lives who can protect their environment. Until now, some poor countries in Africa still continue using chemical pesticides against

The organochlorine pesticide DDT (dichlorodiphenyl-trichloroethane) was heavily used in the U.S. since its inception in the 1940’s. It was a favored insecticide by many, especially when it was once accredited by eradicating mosquitoes that carried malaria in some parts of the world. Due to the possible health effects and growing concern of the human and wildlife population, the use of DDT was banned from the U.S. in 1972. However, DDT, like many organochlorines, it is highly persistent in the environment through bioaccumulation. The chemical concentration of DDT increases as it moves through the upper levels of the food chain, more specifically because it deposits itself in adipose tissue cells. The half-life of DDT inside the body is 10

While DDT is still banned, there is the factor of biological magnification that is still present today. Biological magnification is the process in which chemicals of small doses are absorbed into the fatty tissues of animals through the water they drink, and as they are absorbed into the fatty tissues, they are then passed down to the offspring of the animals through the mother’s milk, and are absorbed into the offspring’s fatty tissues. This is present in humans just as much as animals, and has lead to the fact that DDT still exists in our ecosystem to this day.

Dichlorodiphenyltrichloroethane or “DDT” is an organochlorine insecticide that was first created in 1874. DDT was mostly used as a pesticide for insect control in the US until it was canceled in 1972 by the United States Environmental Protection Agency(USEPA). DDT was also used in WWII to control diseases such as malaria, typhus, and bubonic plague. DDT has since been outlawed because of its adverse health effects on humans and wildlife.

DDT is an insecticide that is known to be particularly effective in controlling the spread of malaria-bearing mosquitos. However, the use of DDT is also controversial because of its negative effects on the environment and the potential risks to human health, which were brought to attention in Rachel Carson’s hugely influential Silent Spring (1962). DDT has been banned in the United States for over thirty years, largely due to the response Silent Spring incited in the public (Bailey, 2004). Malaria remains an issue that is especially prevalent in developing countries; it is also these countries that often rely on foreign aid, and that aid occasionally comes with the condition that the use of DDT be banned.

Discovery of organochlorine pesticides (OCPs) was a major achievement in chemistry in 1940s that proffers solution to the menace of pest invasion on agricultural farms at the time. However, this success was short lived when Rachael Carson published the book title “silent spring” in 1962 that calls the attention of the world to the detrimental effect of continuous application pesticides and it derivative compounds on human and the environment (Ref). World health organization (WHO) compiled fact sheet recently, gave an estimated value of over three million cases of pesticides poisoning that are reported in yearly with over 200,000 result into death globally (REF)WHO, 2009.

DDT is dichloro-diphenyl-trichloroethane a synthetic insecticide .This insecticide save the lives of hundreds of millions of people.It also damaged the environment in a way.The short answer is that it is an insecticide that did good but also had bad effects due to its use.Many people owe their lives to this insecticide but where it did good it also did its damage.

This brings me to my next point, the proper usage of DDT in the modern age is to use very small amounts indoors instead of massive amounts everywhere, as is the American way. We managed to make malaria one of the most difficult things to catch in the western hemisphere with DDT and responsible usage can do it again with less dramatic side-effects. With both cost and efficiency being the most important factors in most large quantity buyouts there are very few reasons not to accept it as a solution to an endemic disease that affects seemingly exclusively

There are many contributions to causing many health issues, one, in particular, is cancer. The tap water that we drink contains chemicals that contribute to causing cancer. One specific chemical is DDT, scientifically known as dichlorodiphenyltrichloroethane, it is an odorless chemical that has no taste, that is used as an insecticide. In addition, the chemical is also used to fight against diseases. According to the Environmental Protection Agency (EPA), “DDT (dichloro-diphenyl-trichloroethane) was developed as the first of the modern synthetic insecticides in the 1940s. It was initially used with great effect to combat malaria, typhus, and the other insect-borne human diseases among both military and civilian populations” (EPA). Although

DDT (dichloro-diphenyl-trichloroethane) is an insecticide manufactured in 1874 however discover by a Swiss chemist Paul Hermann Muller 1939 (Ganzel, Reinhardt, 2003). This inexpensive pesticide was extensively used on crops, from 1945 to 1972( ) DDT was also used During World War II to help combat disease like malaria passed on by lice and mosquitoes which caused illness and death.). Although DDT seemed like a miracle at the time its over uses slowly resulted in to negative side effects

After viewing the studies held in the United States and Africa, I believe that the use of DDT in the United States or Africa is not ethical. If I were a politician or community leader, I would ban the use of all the insecticides that harm people and the environment. Even if some will argue that their current use in some areas shows that their perceived benefits outweigh the health and environmental risks, but I strongly believe that the use of DDT is not an appropriate insecticide. According to United States Environmental Protection Agency, DDT is known to be very persistent in the environment and stays for a significant period of time; it will accumulate in fatty tissues, and can travel long distances in the upper atmosphere (EPA, n.d.).

In the end the measurements of effectiveness were pretty shocking. For the ITNs trials, it was shown that 45% of the An. gambiae were extinguished with chlorpyrifos methyl-treated net and about 30% for the lambda-cyhalothrin-treated net. However, for the IRS trials they found a brilliant 96% An. gambiae mortality rate with chlorpyrifos methyl, 50% rate for DDT, and 31% for lambda-cyhalothrin.For both ITNs and IRS the Cx. quinquefasciatus mortality rates were significantly lower, despite CM’s 66%, every other chemical killed about 15% or lower. The overall research depicted that CM was far more effective at defeating these specific vectors of mosquito than the other chemicals tested. They continued testing for eight weeks and their data proved that CM continued providing strong results the whole time as DDT and LC significantly decreased in ability to kill these mosquitos over time. These results provide striking evidence that DDT alternatives not only work well but can surpass DDT’s efficiency and longevity.The investigators conclude that with modern technology cost effective chemically formulated alternatives to DDT can be used to help eradicate the spreading of malaria.
