Morphine is a phenanthrene opioid receptor ?-opioid receptor agonist, ?-opioid's action is associated with spinal analgesia, miosis ( pinpoint pupils ) and psychotomimetic effects . ?-Opioid is thought to play a role in analgesia . suggesting downstream involvement of the ?-receptor in the actions of morphine.

In addition to lead, coal ash typically contains variable but significant concentrations of polynuclear aromatic hydrocarbons ( PAHs; e . g ., benzo ( a ) anthracene, benzo ( b ) fluoranthene, benzo ( k ) fluoranthene, benzo ( a ) pyrene, indeno ( cd ) pyrene, phenanthrene, anthracene, and others ).

"Coelogyne cristata " contains coeloginanthridin ( 3, 5, 7-trihydroxy-1, 2-dimethoxy-9, 10-dihydrophenanthrene ), a 9, 10-dihydrophenanthrene derivative, and coeloginanthrin ( 3, 5, 7-trihydroxy-1, 2-dimethoxyphenanthrene ), the corresponding phenanthrene analogue, coelogin and coeloginin.

Report authors noted that, " emissions of organic substances with potential toxicity to humans and the environment are a major concern surrounding the rapid industrial development in the Athabasca oil sands region ( AOSR ) . " This study found that tailings ponds were an indirect pathway transporting uncontrolled releases of evaporative emissions of three representative polycyclic aromatic hydrocarbon ( PAH ) s ( phenanthrene, pyrene, and benzo ( a ) pyrene ) and that these emissions had been previously unreported.

BjF can be obtained when either 2-( 1-chloroethenyl ) benzo [ c ] phenanthrene or 6-( 1-chloroethenyl ) chrysene is treated by flash vacuum thermolysis ( FVT ) at high temperatures ( > 900 �C ) followed by ring rearrangements ( ring contraction / expansion ) to selectively yield BjF . benzo [ k ] fluoranthene may also be converted via similar processes to BjF by FVT at temperatures e " 1100 �C ( 6 % yield ) or e " 1200 �C ( 11 % yield ) with 38 % mass recovery.

Tobacco smoke may be grouped into a particulate phase ( trapped on a glass-fiber pad, and termed " TPM " ( total particulate matter ) ) and a gas / vapor phase ( which passes through such a glass-fiber pad ) . " Tar " is mathematically determined by subtracting the weight of the nicotine and water from the TPM . However, several components of tobacco smoke ( e . g ., hydrogen cyanide, formaldehyde, phenanthrene, and pyrene ) do not fit neatly into this rather arbitrary classification, because they are distributed among the solid, liquid and gaseous phases.
