In this study, the development of the technique APCIþ LC/MS/MS allowed the detection of phenanthrene, pyrene and metabolites of alkyl homologs in fish bile (in situ) and in urine of crabs. Laboratory experiments were carried out exposing crabs from an unpolluted mangrove (Barra de Guaratiba) to phenanthrene, and to the alkylated homologs 1-methyl phenanthrene and 2,6,9-trimethyl phenanthrene. Urine samples were collected at 0, 24, 48, 72, and 96 h. Fishes were captured from strategic sites from Guanabara Bay. Hydroxylated metabolites of phenanthrene, epoxides, orthoquinone and glucoside conjugates were identified in both samples. The method APCIþ LC/MS/MS showed to be effective in a preliminary assessment of phenanthrene metabolite formation, although the low concentrations of 1-methyl phenanthene and 2,6,9-trimethyl phenanthrene did not allow a systematic evaluation of data. The method, however, proved to be excellent tool for studies of PAHs metabolites due to the high selectivity, sensitivity and separation attained. |

Extensive livestock represents around 93% of cattle production in Brazil and pasture is its main food source. For this reason, the sector considers pasture degradation an important problem, being responsible for economic and environmental losses. Several sources indicate that more than 60% of the 160 million hectare of Brazilian pastures shows some level of degradation. The need for precise information about degraded pasture levels, localization and quantities leaded to the GEODEGRADE project. More details and results can be found at the website: http://www.geodegrade.cnpm.embrapa.br. |
