There are many applications in which RMs and CRMs are used, but those that are relevant to analytical chemistry, including environmental, industrial, bio-medical, and forensic apphcations and that directly influence Total Quality Management (TQM) can briefly be grouped into the main categories listed below. 

Pharmacologically, carbofuran inhibits cholinesterase, resulting in stimulation of the central, parasympathetic, and somatic motor systems. Sensitive biochemical tests have been developed to measure cholinesterase inhibition in avian and mammalian brain and plasma samples and are useful in the forensic assessment of carbamate exposure in human and wildlife pesticide incidents (Bal-lantyne and Marrs Hunt and Hooper 1993). Acute toxic clinical effects resulting from carbofuran exposure in animals and humans appear to be completely reversible and have been successfully treated with atropine sulfate. However, treatment should occur as soon as possible after exposure because acute carbofuran toxicosis can be fatal younger age groups of various species are more susceptible than adults (Finlayson et al. 1979). Carbofuran labels indicate that application is forbidden to streams, lakes, or ponds. In addition, manufacturers have stated that carbofuran is poisonous if swallowed, inhaled, or absorbed through the skin. Users are cautioned not to breathe carbofuran dust, fumes, or spray mist and treated areas should be avoided for at least 2 days (Anonymous 1971). Three points are emphasized at this juncture. First, some carbofuran degradation... 

The series of regioisomeric amines 48-50, methamphetamine (29) and phentermine (31), can be identified in forensic screening analyses by RP-HPLC-UVD (254/280 nm dual accessory) using a Cis stationary phase and a mobile phase buffered at pH 3.0. The capacity factors and retention times increase in the order 48 < 49 < 29 < 31 < 50. Other methods for identifying these compounds failed for example, the base peak in MS is m/z = 58 for all five compounds, corresponding to a loss of a benzyl group from the molecular peak also their IR and UVV spectra are too similar to be useful for this...
