, 2014 The aquatic humic substances have great environmental importance to have the ability to complex metal ions present in the environment influencing their availability, making them generally less toxic to biota. Metallothioneins (MT) have the characteristic of regular metals on aquatic organisms being induced in the presence of metals and other compounds ...

, 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

Determinação do coeficiente de distribuição (Kd) de benzo(a)pireno em solo por isotermas de sorção [PDF]
Quimica Nova, 2006 Leaking of diesel oil from gas stations is frequent in Brazil. The presence of polycyclic aromatic hydrocarbons (PAHs), which are highly toxic is an indication of contamination by heavy hydrocarbons from diesel oil. Here were present the determination of the distribution coefficient (Kd) of benzo(a)pyrene (the most carcinogenic of the PAHs) in tropical
