DEET Chemistry (Dimethyltoluamide)

DEET Chemistry (Dimethyltoluamide) If you live in an area with biting insects you have almost certainly encountered an insect repellent that uses DEET as its active ingredient. The chemical formula for DEET is N,N-diethyl-3-methyl-benzamide (N,N-dimethyl-m-toluamide). DEET was patented by the U.S. Army in 1946 for use in areas with heavy biting insect infestation. It is a broad-spectrum repellent that is effective against mosquitoes, flies, fleas, chiggers, and ticks. DEET has a good safety record and is less toxic to birds and other mammals than many other insect repellents, but all DEET products should be handled with care. DEET Safety DEET is absorbed through the skin, so it is important to use as low a concentration as is effective (10% or less for children) and as small an amount as is necessary. Up to a certain point, protection against insects increases with higher DEET concentration, but even low concentrations will protect against most bites. Some people experience irritation or an allergic reaction to DEET-containing products. DEET is toxic and potentially fatal if swallowed, so care should be taken to avoid applying repellent to hands or face or anything a child might put in the mouth. DEET should not be applied to areas with cuts or sores or around the eyes, since permanent eye damage can result from contact. High doses or long-term exposure to DEET have been associated with neurological damage. DEET can damage some plastics and synthetic fabrics, such as nylon and acetate, so be careful not to damage clothing or camping equipment. How DEET Works Biting insects use chemical, visual, and thermal cues to locate hosts. DEET is believed to work by blocking the chemical receptors for carbon dioxide and lactic acid, two of the substances released by our bodies that serve as attractants. Although DEET helps keep insects from locating people, there is probably more involved in DEETs effectiveness, since mosquitoes wont bite DEET-treated skin. However, skin only a few centimeters away from DEET is susceptible to bites. Recommendations for Using DEET Despite its hazards, DEET remains one of the safest and most effective insect repellents available. Here are some tips for using DEET safely: Reduce your need for repellent. Avoid behaviors that will attract biting insects (e.g., avoid strenuous exercise or eating lots of high sodium or potassium foods prior to going outdoors, which increase carbon dioxide release).Avoid applying chemicals that attract biting insects (e.g., floral-scented perfumes, scented sunscreens, dryer-sheet-scented clothes).Where possible, apply DEET-containing repellent to clothes rather than to skin.Apply DEET in a well-ventilated area.Avoid applying DEET to hands, the face, or any injured or sensitive skin.Avoid behaviors that will lessen the duration of DEET effectiveness (e.g., perspiration, rain, mixing with sunscreens).When you come indoors, wash off DEET-containing products using warm, soapy water.

Homework - Case Study Example Apart from the time element, a firm must clearly define the prospects of the Information Security Officer and determine whether a worker is capable of filling the role (Putvinski 1). A firm is only as strong and tough as its weakest link, and when the organization works with third-party contributors their information security collapse can become the organization’s issue. Organizations should ensure that they document which vendors get confidential information, in addition to how this information, is taken care of when in the position of the vendor (Putvinski 1). The lack of authoritarian vendor guidelines could raise the risk of releasing a client’s private information. Documents do not storm out of the organization on their own. Having strict rules regarding who can physically access the offices, as well as how they gain entry, might decrease the possibility that an unauthorized person is present illegally to take information (Putvinski 1). The next step is to make sure that an organization’s documents how physical information is kept and destroyed. The issues discussed in student 1’s paper slightly resemble the findings in my paper. Student one talked about security issues with regards to protecting information systems through incorporating security policies. Such a topic is extremely wide in the IT field, and I feel that the student could have explained further as to the types of policies that could be implemented in order to secure our information systems. The second student’s paper was extremely educative. The student focused on the diverse fields of the security best practices touching over every security part that information systems involve. The paper also mentions some of the issues that I discussed in my paper such as physical security, vendor management and information security officers. Such a paper would be extremely helpful to someone who, in
