“…The highest mean OCP levels were still observed in Suzhou (34.3 ng/g). The DDT concentrations in this region were higher than many of the concentrations (with average values of <12.6 ng/g) recently reported in China (Tan et al 2009;Zhong et al 2011;Yang et al 2013). Our DDT levels were within the range recently reported in riverine sediments in the USA Fig.…”

Polybrominated diphenyl ethers (PBDEs), organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs) in 25 surface sediments in three cities (Nantong, Wuxi, and Suzhou) in the Yangtze River Delta, eastern China were measured. The mean concentrations were 378, 45.8, 1.98, 4,002 ng/g for PBDEs, OCPs, PCBs, and PAHs, respectively. Their levels in the sediments in the three cities were generally consistent with the city industrialization. PBDEs and OCPs were markedly dominated by deca-BDE (>90 %) and DDTs (>70 %). A principle component analysis of the analytes identified three major factors suggesting different sources of the contaminants in the sediments. PBDEs and the organic carbon in the sediments have common sources from industrial activities; whereas OCPs and PCBs, correlated with the second factor, were mainly from historical sources. The third factor with loadings of PAHs is indicative of various combustion sources. Ecological risk assessment indicated that the potential highest risk is from DDTs, for which 22 sites exceed the effects range low (ERL) values and three sites exceed the effects range median (ERM) value.

“…(Xing et al, 2011;Yang et al, 2013). Briefly, aliquots of 10 g of freeze-dried sediment samples were spiked with 20 ng of 2,4,5,6-tetrachoro-m-xylene (TCmX) and decachlorobiphenyl (PCB209) as surrogates for OCPs, and were spiked with 10 ng of naphthalene-d8, acenaphthene-d10, phenanthrene-d10, chrysene-d12, and perylened12 as surrogates for PAHs.…”

ResumenRecientemente se han reportado residuos de plaguicidas en el ambiente como resultado de las aplicaciones de estos productos durante varias décadas. A nivel mundial se presentan problemas atribuidos a los efectos de la contaminación por plaguicidas sobre los recursos naturales; sin embargo, en México, no existen suficientes estudios de contaminación por plaguicidas. El objetivo fue evaluar la presencia de plaguicidas en suelos de siete localidades de cinco municipios de la Comarca Lagunera en el estado de Coahuila, se realizó un muestreo de suelos a cinco profundidades (0-8, 8-23, 23-38, 38-53 y 53-68 cm) a razón de una muestra compuesta por hectárea para determinar el grado de contaminación del suelo por plaguicidas. Se utilizó el método soxhlet para la extracción de plaguicidas en la muestra y un Kuderna Danish, para la concentración. Se utilizó un cromatografó de gases. Se encontró que el díeldrin fue el único plaguicida organoclorado presente en los suelos estudiados; las capas superficiales del suelo (0-8 y 8-23 cm) mostraron las mayores concentraciones de díeldrin. El AbstractPesticide residues have recently been reported in the environment as a result of applications of these products for several decades. Globally, there are problems attributed to the effects of pesticide contamination on natural resources; however, in Mexico, there are not enough studies of pesticide contamination. The objective was to evaluate the presence of pesticides in soils of seven localities of five municipalities of the Comarca Lagunera in the state of Coahuila, a soil sampling at five depths (0-8, 8-23, 23-38, 38-53 and 53-68 cm) at the rate of a composite sample per hectare to determine the degree of soil contamination by pesticides. The soxhlet method was used for the extraction of pesticides in the sample and a Danish Kuderna for the concentration. Gas chromatography was used. It was found that dieldrin was the only organochlorine pesticide present in soils studied; the superficial layers of the soil (0-8 and 8-23 cm) showed the highest concentrations of dieldrin. The organic matter content, clay percentage and pH of the soil were the most influential characteristics on 1692 Rev. Mex. Cienc. Agríc.
