Temperature and humidity are two most vital environmental factors that contribute to the transmission of malaria from ecological zone to another. Due to mosquito is the main organism transmitting malaria, the place that mosquito lives is where spread malaria. Mosquitoes need water to finish their life cycle, the place with water is an optimal environment for pupa mosquitoes to live, because when the mosquitoes are pupas, they hanging from the surface of the water.
DDT is one of the organochlorine insecticides which used after World War II. It was used widely and was found to be deadly to insects (2). DDT is a man-made chemical used all over the world to control and eradicate insets which threat the growth of crops and carry disease like malaria and typhus (2).
DDT is a white and crystalline powder with little taste which has very low solubility in water. It does not break down in the environment or in organisms (3). First, DDT will not dissolve in water because it is water insoluble and lipid soluble; however, it will in the fats of organisms (3)and has strong potential for entry into fresh water. It is difficult to wash away in the environment due to DDT is insoluble in water (3). ...

- What are the Chemical and Physical information of DDT. According to Agency for Toxic Substances and Disease Registry (ATSDR) Dichlorodiphenyltrichloroethane (DDT) is a synthetic organochlorine insecticide used in agriculture. DDT is a synthetic chemical mixture of three isomers. DDT consists of DDE and DDD as trace contaminants. DDT was applied as a pesticide in agricultural crops and insects that are vectors of diseases such as malaria and typhus. DDD was used as pesticide however, in a small scale compared to DDT....

- Introduction Nearly half a billion people are infected with malaria each year and more than a million people die from this disease. Malaria is transmitted through the bite of a female Anopheles mosquito infected with malaria parasites. When the parasites enter the human body, it slowly destroys the body’s red blood cells, eventually killing the patient if left without undergoing immediate treatment (Stanmeyer 2007). One of the means employed to counter the spread of malaria is through the use of DDT as an insecticide to kill the mosquitoes before they are able to infect more people.... [tags: Diseases/Disorders]

- Malaria and DDT Malaria has been a huge problem among many developing nations over the past century. The amount of people in the entire world that die from malaria each year is between 700,000 and 2.7 million. 75% of these deaths are African children (Med. Letter on CDC & FDA, 2001). 90% of the malaria cases in the world are located in Sub-Saharan Africa. Once again, the majority of these deaths are of children (Randerson, 2002). The numbers speak for themselves. Malaria is a huge problem and needs to be dealt with immediately.... [tags: Health Biology Essays]

- ... An alternative solution should be considered despite the potential higher economic cost, as the costs to public health are tremendous. In addition to the possible detriments for human health, DDT wreaks havoc when it is introduced into the environment. Due to the fact that it is readily soluble in fats but not so much in water it persists in the environment for obscene amounts of time. The World Health Organization states that this can be up to 12 years before this substance and its byproducts finally leave the environment (WHO p.4).... [tags: insecticides for Malaria control]

- To take a trip back to the 1940s, when most of America was so deeply engulfed in financial turmoil from the depression, while also bolstering up for a second World War, we would meet a young, but brave women named Rachel Carson. She was focused on a different type of disaster taking place; the implementation of a new pesticide called DDT. With this new chemical being sprayed throughout the US and other countries, Carson took notice to the environmental issues that were arising along with it. This pesticide brought implications and topics for her to question including the ‘separation ' of humans from the environment, biodiversity loss, nature being truly defined, conservationism and creating...

- Assignment 4 - Formal Classroom Observation A formal observation was conducted on a tenure history teacher, using the McRel Evaluation tool. Prior to the evaluation, the teacher met with the administrator to discuss the lesson objective and talk about the dynamics and make-up of the classroom. This classroom is a 9th grade inclusion classroom, consisting of a total of 21 students, ten with individual education programs. There are two teachers in the classroom, a general education teacher and a special education teacher.... [tags: Education, Observation, Observable]

- Over 39 years have passed since the nationwide ban of a well-known pesticide, dichlorodiphenyltrichloroethane (DDT) (1), yet it still has an important role in public health as well as the environment. DDT is a persistent toxin, having a long half-life of 2 to 15 years terrestrially and 150 years aquatically (as cited in 5). It was originally used in World War II to control malaria and yellow fever then became a main staple in pesticide control for crops. Because DDT was a highly effective pesticide for malaria it is still used in areas where the disease is prevalent.... [tags: Use, Impact, Importance]

- Naturalistic observation takes place as scientists perform observations in a naturally occurring situation, without becoming actively involved. In performing naturalistic observations, a scientist does not make an effort to manipulate or change what is occurring. The purpose of this kind of experimentation is to create a detailed record of the events that happen and of perceptible associations between events, without having any control on the results. Apparently the objective in performing naturalistic observation is to arrange the data collection so that what is going on is comprehensible to the observer, but is not so important or conspicuous that they become the focus of attention or mat...

- Malaria There are a great number of diseases that are endemic in many of the poorer, developing nations due to the lack of sanitation and disease prevention programs in these areas. The steady increase of malaria epidemics in many of the African countries is a point of great concern, because this continent is home to 90% of the world’s total cases of this particular disease. Malaria gets its name from “mal aria,” meaning bad air, because patients used to blame the sudden illness on the poor air quality of the nearby swamps.... [tags: Exploratory Essays Research Papers]

- Malaria Malaria parasites have been with us since the beginning of time, and fossils of mosquitoes up to thirty million years old show that malaria’s vector has existed for just as long. The parasites causing malaria are highly specific, with man as the only host and mosquitoes as the only vector. Every year, 300,000,000 people are affected by malaria, and while less than one percent of these people die, there are still an estimated 1,500,000 deaths per year. While Malaria was one of the first infectious diseases to be treated successfully with a drug, scientist are still looking for a cure or at least a vaccination today (Cann, 1996)....
