Download file to see previous pages DDT is slowly absorbed in the gastrointestinal tract; however, if the DDT has been dissolved in fats from vegetables or animals, then the absorption rate is enhanced up to 1.5 times. The oral ingestion of DDT usually results in convulsions after 2 hours, if the rate of administration is twice that of the oral LD50 value. It has also been established that absorption of DDT by the skin is minimal (DDT).
Subsequent to absorption, DDT accumulates in the tissues, especially in the adipose tissue. Many studies have reported the storage of DDT in the central nervous system, blood, liver, heart and kidneys. The body excretes DTT in milk and urine (DDT).
A small amount of the ingested DDT changes into DDE, whose toxicity is much less. The latter is impervious to biotransformation, and consequently persists in the adipose tissue, indefinitely. The chief detoxification route for DDT is transformation to DDD, which quickly changes into the water soluble DDA, and then excreted (DDT).
The rate of elimination of DDT from the body has been assessed at 1% of the amount stored in the body. DDA excretion in the urine is around 47% of the ingested precursor material; however, this loses significance, when the amount of DDT being ingested increases. Moreover, there has been a reasonable correlation between the DDA concentrations in urine and DDT levels in body fat (DDT).
The different routes of exposure, associated with DDT are first; oral which transpires when there is ingestion of DDT or food contaminated with DDT. Second; by inhalation; however, this is not of much importance, because absorption is insignificant, due to the non – volatile nature of DDT. Third; absorption through the skin, which is not an important route. DDT absorption by the skin is negligible, and an increase is effected, if it is dissolved in oil. Fourth; absorption through the eye, ...Download file to see next pagesRead More

Malaria control and intervention by DDt

.... Environmental impacts of the use of DDT, however, cannot be ignored, as they are the major pollutant of the eco- system. But developing country’s reliance on DDT use for Malaria control cannot be overlooked just as well. These countries and its inhabitants are unable to afford expensive therapies and preventive techniques. Moreover, Malaria is reemerging in the countries where it was previously controlled, when they discontinued the use of DDT sprays due to national and international environmental concerns. Several field studies provide evidence of reduced...

Article Critique

...?Article Critique Effective Malaria control involves more than just combating mosquitos. In the modern era, the side effects of the chemicals used tofight such vector borne diseases have become just as much important to be considered as fighting the diseases themselves. The debates on benefits versus risks of these chemicals have heated up more than ever. Of these chemicals, the most effective and arguably the largest life-saving chemical ever made by man against vector borne diseases is DDT. While it has been banned in most countries due to environmental and health concerns, its unparalleled efficiency and effectiveness have made it...

DDT and malaria

...long residual action. The common re-spraying of chemicals with a short residual activity known as DDT alternatives is not a cheap method of malaria control in remote areas. As developing countries are avoiding house spraying plans, they have slowly reverted to the situations of unpreventable rural malaria that was there before mid 1940s. Currently, the basic relationship of rural people with malaria, and the expense of using house spraying to prevent mosquitoes in rural areas is an old idea that needs to be re-invented. The notion that malaria should be prevented by combining many methods of mosquito...

...such as spasticity, hypotonia or hemiparesis (Davidson). Malaria Diagnosis and Treatment World Malaria Report 2010 has recommended a parasitological confirmation of diagnosis to be completed by either rapid diagnostic test (RDT) method or microscopy. Currently, the use of RDT has increased considerably from around 200,000 in 2005 to almost 30 million during 2009. Microscopic examination has been reducing in most parts of the world including regions of the Americas and Europe (World Malaria Report 25). World Health Organization guidelines for treatment of Malaria can be described as per the following (World Malaria Report 5). 1. Rapid...

The Use of DDT in Malaria Vector Control

...?Article Critique: The Use of DDT in Malaria Vector Control HOW WOULD YOU USE A RISK VERSUS BENEFIT ASSESSMENT, AND WHAT OTHER TYPES OF TOXICOLOGYDATA WOULD YOU NEED TO MAKE THIS DECISION? REFER TO CHAPTER 12. This part of the study will broadly focus on analyzing the term dichlorodiphenyltrichloroethane (DDT) and the risks as well as the benefits associated with this term would be assessed. In this regard, DDT is mainly used for the purpose of controlling certain critical diseases which itself can be regarded as a positive aspect. DDT has been strongly...

...therapy (ACT) is the best available treatment for malaria. International health organizations including WHO and CDC recommend that all suspected malaria cases should be confirmed through the use of parasite-based diagnostic testing, either rapid diagnostic or microscopy test prior to administering treatment. Parasitological confirmation results can be available in less than 15 minutes. It is important to note that treating malaria solely on the basis of symptoms should be considered only when it is not possible to conduct parasitological diagnosis (Isle, 2001). “Prevention is better than cure.” This saying is very appropriate in regard to malaria. Since...

...? Biology: Malaria. of the institute: Clinical trial can be defined as a controlled test of any new drug or any innovative invasive medical device to be used by human beings. A clinical trial follows a well detailed plan and protocol. For example in United States, the clinical trial is generally conducted following the FDA directions and, it cannot be made available for clinical use unless they endorse it. Currently malaria clinical trial is very essential due to the problems and dangerousness of malaria amongst people (Isle, 2001). For this reason, I will not hesitate to be part of those who participate in a current clinical trial. This...

Should DDT Be Used to Control Malaria

...Should DDT Be Used to Control Malaria? Observation and Background Information The Disease, the Vector and the Parasite Malaria is a common and life-threatening disease, prevalent in many tropical and subtropical countries in Central and South America, Africa, Asia and Oceania (Guidelines, South Africa). It was discovered in the 19th century and the causative parasite Plasmodium was identified in 1897 by Sir Ronald Ross for which he won the Nobel Prize in 1902 (MMV). Worldwide, 300 to 500 million people suffer from this disease annually (Statistics of malaria). In Africa alone, more than a million children die of...

DDT

...Malaria is one of the leading causes of high mortality rate especially to young children below the age of five years and pregnant women in Africa (ATSDR, 2002). High resistance to drugs and insecticides has made the control of malaria a challenging task globally. However, of all insecticides used to control malaria vectors, DDT has the highest proven efficacy. The use of DDT for internal residual spraying is one of the most effective methods of controlling the spread of malaria (WHO, 2007). DDT has high toxicity...

Disease Control and Prevention: Malaria

...mortality, stillbirth and low birth weight. Such a factor as medical care (or its absence in the first days of disease) increase the risk of severe complications after malaria, and the density of population may increase the risk of spreading this disease (World Health Organization, 2013). It is important to control the places where Plasmodium and Anopheles may live. The effective measures are swamp draining and using of the insecticides. These measures helped to decrease the risk of malaria in Asia and Africa (World Health Organization, 2013). However, it should be taken into account that Anopheles mosquitos become resistant to the insecticides. The insecticide also has...
