A number of other chemicals are used for the control of crop pests. Presently, only selected chemicals are discussed here. These include synthetic pyrethroids, plant regulators, and a rodenticide.

Structure-activity data for plant regulators are not very abundant in comparison with similar information on pesticides. This stems partly from the relative novelty of plant regulators and partly from the diflBculty in obtaining biological test data. While research in plant regulation has been active for scores of years, identification of specific regulators— more precisely, plant hormones— has been generated within the past 35-40 yrs.

The OSHA limits, regulations, and recommendations apply to in-plant air quaUty. Improperly filtered exhaust air may cause a plant to be in violation of the EPA standard, therefore these data should not be confused with the EPA limit for airborne lead, 1.5 fig lead/m, measured over a calendar quarter, which pertains to the exterior plant environment and emissions. The installation and proper maintenance of exhaust filtration systems enables most plants to comply with the EPA limits for airborne lead (see Lead compounds, industrial toxicology). 

The safety aspects of pdot-plant constmction and operation will continue to grow driven by both regulation and an increased awareness of the potential hazards. This will also require specialized skills and training at ad. levels. 

Sulfonation Plant Operations and Gas Effluent. Standards governing U.S. sulfonation plant gas effluents differ depending on whether or not the plant is equipped with a H2SO4 scmbbing system for adsorption of SO gas (see Fig. 3). The installation of the SO adsorber system qualifies the plant as a sulfuric production plant which has stringent regulations. Limitations and typical effluent from the sulfonation system are as follows ... 

Biosynthesis of Tea Flavonoids. The pathways for the de novo biosynthesis of flavonoids in both soft and woody plants (Pigs. 3 and 4) have been generally elucidated and reviewed in detail (32,51). The regulation and control of these pathways in tea and the nature of the enzymes involved in synthesis in tea have not been studied exhaustively. The key enzymes thought to be involved in the biosynthesis of tea flavonoids are 5-dehydroshikimate reductase (52), phenylalanine ammonia lyase (53), and those associated with the shikimate/arogenate pathway (52). At least 13 enzymes catalyze the formation of plant flavonoids (Table 4). 

Silver-brazed joints are used when temperature or the combination of temperature and pressure is beyond the range of soldered joints. They are also more reliable in the event of plant fires and are more resistant to vibration. If they are used for fluids that are flammable, toxic, or damaging to human tissue, appropriate safeguarding is required by the code. There are OSHA regulations governing the use of silver brazing alloys containing cadmium and other toxic materials.

Show the complex iterations between government laws and regulations and the PSA response to not only comply but to protect the process industry. The real impact of the accident at the Three-Mile Island nuclear plant was not radiation, which was within regulations but financial losses to the utility and the acceptance of nuclear electrical f>ower in the United States. The effects of the Bhopal accident were in human life but it also had a profound effect on the chemical industry financially, and its acceptability and growth. Present the mathematics used in PSA in one chapter to be skipped, studied, or relerred to according to the readers needs.
