Research team “uncovered a PAH bonanza” — And just 190 parts per BILLION of PAHs is “considered pretty toxic” says professor at NASA installation


BP gusher left deep sea toxic for a time, study finds, ScienceNews Magazine Web Edition, November 1, 2010:

Explains [Biological oceanographer Steven Lohrenz of the University of Southern Mississippi at the Stennis Space Center], “190 [ppb of total polycyclic aromatic hydrocarbons (PAHs)] is considered pretty toxic”...

Although the university scientists had known the BP oil would contain the PAHs, “we weren’t sure, quite honestly, that we would see anything substantial,” Lohrenz concedes. In fact, his team uncovered a PAH bonanza — both in terms of the pollutants’ concentrations and their persistence over time and space.

Lohrenz also noted:

"PAHs were going to be critical to understanding the ecological impacts of this event... These are some of the most toxic components in oil.”

    “They found bad things happening to salmon & herring at 1 ppb of PAH” … “At 19 ppb, They found you would kill half of the exposed population.”
