Opioid Analgesics: Chemistry and Receptors

The swiftly burgeoning examine of the previous 20 years on agonist-antagonist analgesics and opioid receptors makes this exhaustive evaluate of opioid anal­ gesics quite correct and well timed. After an introductory bankruptcy the extra 12 chapters commence logically with morphine and congeners (4- epoxymorphinans) and finish with opioid receptors.

1 ng/l water at two reference stations in the open sea [277]. Notable concentrations have been measured in Tokyo Bay and in the Strait of Malacca where ship traffic is heavy, whereas concentrations elsewhere in the open sea have remained below the analytical threshold [278]. However, indirect measurements have suggested the presence of TBT at trace amounts in oceanic waters. 4 ng/l in those of the Southern Hemisphere [279]. Moreover, the contamination of marine mammals constitutes an indication of TBT presence in Atlantic and Pacific waters [17, 280–282].

T. 4 Phthalates Esters of 1,2-benzenedicarboxylic acid (phthalic acid esters, PAEs, phthalates) comprise a group of organic compounds used in large quantities by present day society (Fig. 17). 2 ¥ 10 9 kg during 1994 and has increased by roughly 50% during the last 20 years [214]. PAEs are mainly used as plasticizers in polyvinyl chloride (PVC) plastics and may constitute up to 67% of their total weight.

Simoneit As a result of the widespread and abundant use of PAEs, they have been widely dispersed and detected in waters and sediments [232]. The toxicity or biological effects of PAEs have been reported [233, 234]; therefore, it is prudent to establish a method for precise analysis, characterization, removal, and/or bioremediation of PAEs from both aqueous and solid phase environments.
