What are the different kinds of disinfectant?

Disinfectants are drugs used to kill microrobes on non-living tissue (as opposed to in situ, on living tissue, on non-organic surfaces, etc.). The primary different types include: * Alcohols (Ethyl and Isopropyl) * Aldehydes (from oxidized alcohols) * Oxidizers (H2O2 is especially well known, as is chlorine (bleach)). * Iodine (Betadine et al). * Phenolics (often in mouthwash) * UV light (under special circumstances). Note that the quallity of a disinfectant is that it is basically a topical toxin that does not leave a residue. As such, many other toxins can be used effectively for disinfection. One can even use high-flow sterile saline, which act as a dessicant on bacteria and larger.

A high pCO2 will produce what kind of pH?

A high PCO2 indicates a high percentage of CO2 in the blood measured by the law of partial pressure (a theory from chemistry).

The more CO2 in the blood, the more acidic it becomes. The more O2, the more alkaline.

pH is measured from 1-12. Low pH is acidic and high pH is alkalytic.

Therefore an acidotic state will give you a low pH.

Be aware that there are two measures of pH used in physiology. One is respiratory acidosis/alkalosis and the other is systemic acidosis/alkalosis- which would be the one indicated when using the example of a blood lab such as PCO2 or PO2.

If you took vailum 8 days before your drug test will it show?

This depends on the doage, quantity tested for, and the persons overall metabolism and nutritional behaviour. On average a single dosage can leave the system in as little as 12 hours given the patient is particularly lean and drinks adequate fluids. Tests performed by Militaryagencies tend to be more strict and have an increased chance of showing drugs like Valium for a longer period of time. Increased alcohol consumption during the Valium consumpion and for the period afterwards would also decrease the liklihood that the substance has fully left the body. Microbodies are to some extent unpredictable and levels vary dramatically from one person to another. As always, taking legally prescribed medicines cannot count against you on any urinary anlysis. If symptoms of depression or anxiety or irritably exist there is no reason why a script should not be written for this case. In general its better to have the documentation to prove your legitimate consumption of a pill than to take a chance otherwise. Look at what happened to the guy on A-Team ( www.tvtornado.com ) ...
