Evaluación del efecto de la exposición al hidrocarburo benzo[a]pireno sobre la eficiencia fotosintética de tres microalgas marinas

, 2010
Benzopl_apyrene, (BaP) is a polycyclic aromatic hydrocarbon (PAH) known as the ninth most dangerous substance due to its toxicity and high potential of damage as a carcinogenic and mutagenic substance. Considering the scarce information on the effects of PAHs, and particularly BaP on marine phytoplankton species, the present study was aimed to evaluate
