TOXIC EFFECTS OF POLYCYCLIC AROMATIC HYDROCARBONS IN A WATER MEDIUM FROM DIESEL COMBUSTION

Artigo:

Most energy consumed on the planet derives from petroleum, coal and natural gas and the air pollution caused by such combustion is largely solved in water resources. The reaction produces highly toxic polycyclic aromatic hydrocarbons (PAHs). Current analysis evaluates the toxic effects of gas emissions from the combustion of diesel S10, S50 and B2 in a stationary engine. Methodology comprises the absorption of combustion gases in de-ionized water, with a fixed bed column. Absorption water is used for acute toxicity assays on Mysidopsis juniae, following norms by ABNT 15308. PAHs are quantified by fluorometry. Results showed an average concentration of 34.65 mg.L-1 of total PAH in the collected water sample. A 100% mortality of Mysidacea occurred in all dilutions in the three toxicity assays, except control, with a survival rate of 100% in
