| description | Polybrominated diphenyl ethers (PBDEs)
are considered persistent organic pollutants
because of their ubiquity, persistence and
bioaccumulation. Its harmful effects on
human health and the environment, has led
to its inclusion of the Stockholm Convention.
Little information is found about PBDEs
in abiotic systems of the South America
in open literature. This paper reports the
presence and concentration level of four
PBDEs congeners in Mendoza River,
Argentina. The selected PBDEs were:
2,2',4,4'-tetrabromodiphenyl ether (BDE-47),
2,2',4,4',5-pentabromodiphenyl ether (BDE-99),
2,2',4,4',6-pentabromodiphenyl ether (BDE-
100) and 2,2',4,4',5,5'-hexabromodiphenyl
ether (BDE-153). The analytical methodology
used was head space-solid phase micro
extraction combined with gas chromatographymass
spectrometry (HS-SPME-GC-MS/MS).
Several variables, including pH, salting out,
extraction technique type and extraction
time were studied and optimized over the
relative response the target analytes. The
precision of HS-SPME-GC-MS/MS evaluated
over five replicate, leading RSDs values
<13%, detection limits (S/N=3) ranging
from 0.03 pg ml-1 to 0.12 pg ml-1 and the
calibration graph was linear with r2=0.9959.
BDE-47 and BDE-100 were the predominant
congeners found in the analyzed samples.
Their concentrations ranged from not detected
to 1.9 pg ml-1 and to 0.5 pg ml-1, respectively. |

Los éteres difenil-polibromados (PBDEs) son considerados contaminantes orgánicos persistentes debido a su ubicuidad, persistencia y capacidad de bioacumulación. Sus efectos nocivos sobre la salud humana y el ambiente, han motivado su inclusión en el Convenio de Estocolmo. Poca información se dispone en la bibliografía internacional sobre la presencia de PBDEs en los sistemas ambientales de Sudamérica. Este trabajo reporta la distribución y niveles de concentración de cuatro congéneres de PBDEs en la cuenca del Río Mendoza, Argentina. Los congéneres seleccionados fueron: 2,2',4,4'-tetrabromodifenil éter (BDE-47), 2,2',4,4',5-pentabromodifenil éter (BDE-99), 2,2',4,4',6-pentabromodifenil éter (BDE-100) y 2,2',4,4',5,5'-hexabromodifenil éter (BDE-153). La metodología analítica es la microextracción en fase sólida en espacio de cabeza seguida de cromatografía gaseosa con detección de masas (HS-SPME-GC-MS/MS). Variables tales como pH, fuerza iónica, tipo, tiempo y temperatura de extracción fueron estudiadas y optimizadas. La precisión de HS-SPMEGC- MS/MS fue de RSD <13%, los límites de detección (S/N=3) se establecieron en el intervalo de 0,03 pg ml-1 a 0,12 pg ml-1 y la curva de calibración tuvo un r2=0,9959. BDE-47 y BDE-100 fueron los congéneres predominantes encontrados en las muestras de agua analizadas cuyas concentraciones máximas fueron 1,9 pg ml-1 y 0,5 pg ml-1, respectivamente.
