Safety and Toxicity

Under normal conditions, PMTFPS is relatively inert. Skin tests performed on albino rabbits have shown no dermal irritation or toxicity. In more than 40 years of indns-trial nse of fluorosilicone componnds, no problems have been reported with respect to hnman dermal contact with these materials, nncnred or cnred [96]. It is prndent to minimize the direct contact with the materials and exposnre of personnel to fnmes in the workplace. More on this snbject is discnssed in Chapter 8.

Other factors may include color, toxicity and safety, temperature restrictions, ability to cure at service temperature, resistance to bacterial effects, shelf life and pot life of the paints.

In addition to toxicity and safety data, the preclini-cal package to start clinical studies also contains information on the pharmacology, the pharmacokinetics and metabolism and the galenical aspects of the compound. As a rule there is evidence of pharmacological activity and, if possible, of therapeutic activity in one or more animal models of disease. Ideally there is also information on the in vivo concentration effect relationship. 

Toxicogenomics tries to assess the toxicity and safety of chemical compounds by analyzing gene expression changes detected by measuring mRNA levels using DNA microarrays (1,2).

Commercial WGS catalysts have been optimised for more than 50 years for the massive H2 production in petrochemical plants. However, on-board production requires new catalytic properties such as short response in a dynamic regime, sulfur tolerance, low toxicity and safety (commercial catalysts generally contain Cr and are pyrophoric) and above all a higher efficiency to minimize the size of reactors. Imme-... 

The major activity or obstacle of concern in developing and registering a plant growth regulator, or any pesticide, involves the total toxicity and safety profile. Of primary concern is the impact of federal agency regulations attention is generally focused on the EPA (14, 15, 16, 17, 18). 

The toxicity and safety of aspartame, especially a reputed causal connection with an increased incidence of brain tumors about the time that aspartame was approved (1981], has received much attention in the popular press. A FDA discussion paper (T96-75, November 1996) on the topic can be found at http //vm.cfsan.fda.gov/ kd/tpaspart.html. This discussion paper refutes the association, chiefly on the grounds that the incidence of brain and CNS tumors began its rise in 1973, well before the introduction of aspartame. Since 1985, the incidence of brain tumors has in fact been increasing at a slower rate. The incidence peaked in about 1991 and has declined slightly since then.
