This chapter discusses specific organ systems that contact a variety of substances in the workplace environment (or due to drug abuse and addiction), leading to health hazards. Important organs discussed here include the skin, the respiratory system, the cardiovascular system, the renal system, and the central nervous system (CNS). In the United States and other countries of the world, the application of phenol is on the increase in the manufacture of aromatic compounds, explosives, fertilizers, paints, rubber products, wood preservatives, synthetic resins, drugs and pharmaceutical products, plastics, leather tanning and... 

SAFETY PROFILE Mildly toxic by ingestion. A nuisance dust. Flammable from heat or flame or oxidizers. Mixtures with thiophosphoryl chloride react when heated to form a product that ignites and then explodes on contact with air. Used in coatings, stabilizers, explosives, P.E.T.N resins, drugs, insecticides, and lubricants.

Considerable interest has been shown ia poly(ethylene oxide) for diverse appHcations ia food, drug, and cosmetic products. Such uses fall within the scope of the Federal Food, Dmg, and Cosmetic Act. The U.S. FDA has recognized and approved the use of poly(ethylene oxide) for specific food and food packaging uses. USP/NF-grades of Polyox water-soluble resins (Union Carbide Corp.) are available for pharmaceutical appHcations.

MAI composed of PAIE for application to emulsifiers, drug carriers, and ion-exchange resins [60,61]. Poly(per-fluoropropyleneglycol)-b-poly(acrylic acid) was synthesized initiated with an MPI having fluoroalkyl group in the main chain [62]. It was soluble to water, ethanol, and THF, and showed water repellency, oil repellency, antifouling, and resistance to chemicals.

Co-administration of ofloxacin and chitosan in eyedrops increased the bioavailabUity of the antibiotic [290]. Trimethyl chitosan was more effective because of its solubility (plain chitosan precipitates at the pH of the tear fluid). On the other hand, N-carboxymethyl chitosan did not enhance the corneal permeability nevertheless it mediated zero-order ofloxacin absorption, leading to a time-constant effective antibiotic concentration [291]. Also W,0-carboxymethyl chitosan is suitable as an excipient in ophthalmic formulations to improve the retention and the bioavailability of drugs such as pilocarpine, timolol maleate, neomycin sulfate, and ephedrine. Most of the drugs are sensitive to pH, and the composition should have an acidic pH, to enhance stability of the drug. The delivery should be made through an anion exchange resin that adjusts the pH at around 7 [292]. Chitosan solutions do not lend themselves to thermal sterilization. A chitosan suspension, however.
