Marine protected areas in Latin America and Caribbean threatened by polycyclic aromatic hydrocarbons
Beatriz Zachello Nunes,Eliete Zanardi-Lamardo,Rodrigo Brasil Choueri,Ítalo Braga Castro,Ítalo Braga Castro +4 more
TL;DR: A literature-based analysis investigating occurrence and the possible consequences of polycyclic aromatic hydrocarbons in marine protected areas (MPAs) of Latin America and Caribbean found petrogenic and pyrolytic processes as PAH predominant sources, and were mainly attributed to the proximity to ports, industries and urban areas.

Nitro-PAHs and PAHs in Atmospheric Particulate Matters and Sea Sediments in Hiroshima Bay Area, Japan
TL;DR: In this paper, atmospheric and sea sediment concentrations were measured for eight nitrated polycyclic aromatic hydrocarbons (nitro-PAHs) and three unsubstituted PAHs in a suburban area and sea sediments in the Hiroshima Bay watershed area, Japan, from July to December, 2006 (atmospheric particulate matter) and in September and November, 2004 (sea sediments).
