New England Journal of Medicine and BP Oil Spill

NIOSH standards regarding exposure to certain tar substances.

CANCER warning  includes Lung, Kidney and Skin Cancer.
Via phenanthrene family: pyrene, phenanthrene, acridine, chrysene, anthracene & benzo(a)pyrene).
Yet has any research been done regarding exposure to Corexit covered tar product/ MC252.
PHENANTHRENES-which is lingering in Gulf tar balls.
BP oil not degrading- AUBURN UNIV STUDY Sept 2011:

Vibrio Vulnificus pathogen in Gulf of Mexico tarballs:
AUBURN STUDY on Vibrio Vulnificus in tar balls from N. Gulf Coast:
OIL entered the food chain/zooplankton:

NOAA explains that dolphins will indicate ocean and human health:

SEAGRANT found that dolphins share 13 chromosomes as humans- can they determine health issues? 

Sublethal effects of BP spill:

Oil deposits may have become a chronic source of low-level oil pollution within the spill-affected area-Valdez.
“Subsurface oil was also found at a lower tide height than expected (between 0 and 6 feet), in contrast to the surface oil, which was found mostly at the highest levels of the beach (Table 3).  This is significant, because the pits with the most oil were found low in the intertidal zone, closest to the zone of biological production, and indicate that our estimates are conservative at best.
Are pink salmon or herring injured because of continued intertidal contamination?  Are near shore predators, like otters or sea ducks, at risk because they prey in this zone?  Are the area’s subsistence users avoiding appropriate beaches, or are they avoiding all beaches?”
