“…They mainly originate from anthropogenic activities, such as incomplete combustion of organic materials (e.g., wood, coal oil, gas, tobacco and straw), as well as from automobile exhausts and industrial processes (Yunker et al, 2002a(Yunker et al, , 2002b. As a result, PAHs have been used to assess the magnitude of anthropogenic impacts on the environment (Jones et al, 1989;Page et al, 1999;Liu et al, 2012bLiu et al, , 2012cYang et al, 2012).…”

“…In the oiled colonies, most of the PAH profiles in gull blood were dominated by naphthalene (22-38%), indicating a petrogenic (i.e., derived from petroleum) source (43). Although after the wreck the composition of the Prestige oil was probably altered by weathering (44), naphthalene was also the dominant parent compound found in subsurface waters (45) and intertidal sediments (46) from oiled areas immediately after spill.…”

In this study we tested the use of seabird blood as a bioindicator of polycyclic aromatic hydrocarbon (PAH) pollution in the marine environment. Blood cells of breeding yellow-legged gulls (Larus michahellis) were able to track spatial and temporal changes consistent with the massive oil pollution pulse that resulted from the Prestige oil spill. Thus, in 2004, blood samples from yellow-legged gulls breeding in colonies that were in the trajectory of the spill doubled in their total PAH concentrations when compared to samples from unoiled colonies. Furthermore, PAH levels in gulls from an oiled colony decreased by nearly a third in two consecutive breeding seasons (2004 and 2005). Experimental evidence was gathered by means of an oilingestion field experiment. The total concentration of PAHs in the blood of gulls given oil supplements was 30% higher compared to controls. This strongly suggested that measures of PAHs in the blood of gulls are sensitive to the ingestion of small quantities of oil. Our study provides evidence that seabirds were exposed to residual Prestige oil 17 months after the spill commenced and gives support to the nondestructive use of seabirds as biomonitors of oil pollution in marine environments.

“…HPAs são compostos aromáticos formados por dois ou mais anéis benzênicos, constituídos exclusivamente por átomos de carbono e hidrogênio (Figura 1), organizados sob forma linear, angular ou agrupada (Netto et al 2000). A formação desses contaminantes tem sua origem na combustão incompleta da matéria orgânica, origem essa influenciada principalmente por fatores como temperatura e pressão que direcionam o perfil constituinte dos mesmos (Page et al 1999). Deste modo, incêndios florestais e de campos, assim como a queima de combustível fóssil, seriam as principais fontes de HPAs para o meio ambiente.…”

“…Porém, as maiores emissões provêm de processos industriais ligados à produção de aço e alumínio, da exaustão de incineradores de rejeito e por resíduos sólidos industriais. Atividades petroquímicas como o processo e refino na produção de petróleo, assim como, acidentes que envolvem o derramamento direto de seus produtos e derivados em corpos receptores, como lagos, rios e oceanos, também elevam consideravelmente os níveis ambientais de HPAs (Page et al 1999, Yunker et al 2002, Sisinno et al 2003.…”

Aspectos ecotoxicológicos de hidrocarbonetos policíclicos aromáticos

REsUmoHidrocarbonetos Policíclicos Aromáticos (HPAs) são considerados poluentes orgânicos prioritários em estudos ambientais. Algumas dessas substâncias podem ser consideradas precursoras de ações mutagênicas e tumorais em sistemas biológicos. HPAs são formados exclusivamente por átomos de carbono e hidrogênio e organizados sob a forma de anéis aromáticos fusionados entre si. Essa classe de substâncias tem sua origem na combustão incompleta da matéria orgânica regida principalmente por diferentes fatores físicos, como temperatura e pressão. O transporte de HPAs se dá principalmente através de material particulado fino atmosférico ou por meio aquoso, podendo atingir desta forma regiões distantes de suas origens. HPAs são altamente lipossolúveis e rapidamente absorvidos pelos pulmões, intestinos e pele de homens e animais. Uma vez absorvidos pelas células, os HPAs são metabolicamente ativados e, desta maneira, tornam-se reativos a grupos nuclofílicos presentes em macromoléculas celulares. A formação de adutos de DNA é considerada essencial na carcinogenicidade química desses xenobiontes. Consumidores de alimentos defumados, fumantes, indivíduos em contato com ambiente contaminado (i.e. água e ar), e trabalhadores ocupacionais expostos de forma direta a HPAs podem apresentar elevadas propensões ao desenvolvimento de tumores e câncer.

Policiclic Aromatic Hydrocarbons (PAH) are considered priority organic pollutants in environmental researches. Some of these substances can be considered mutagenic and tumors precursors in biologic systems. PAH are formed exclusively by carbon and hydrogen atoms consisting of two or more fused aromatic rings arrangements. PAH are originated from incomplete burning of organic matter leading by different physics factors as temperature and pressure parameters. PAH are transported mainly through fine particles in atmosphere or aquatic environment and can reach distant areas far from its origins. PAH are lipophilic compounds and quickly absorbed by lung, intestine and skin from human and animals. Once absorbed by cells, PAH are metabolic activated and this way becomes reactive to nucleophilic groups of cellular macromolecules. The formation of DNA adducts is considered essential in the chemical carcinogenic of these xenobiotic compounds. The consummers of smoked foods, people that smokes, live in contaminated environment (e.g. water and air), and occupational workers who are exposed in a direct form to PAH present the higher risks of tumors and cancer development.
