“…The obtained trend of the DDT isomers (DDE>DDT≈DDD) is consistent with the high chemical stability and long half-life of DDE in the aquatic environment in comparison to the parent DDT (25). The DDTs levels found in this study are similar to recent reports for different fish species from the Ionian Sea (29), Gulf of Naples (25), Marmara Sea (30), and Atlantic coastal regions (27) and are higher than those reported for other coastal areas of the Mediterranean (26,(31)(32)(33) (Table 3).…”

“…This theory focuses primarily on physical and chemical mechanisms to estimate chemical fate, ignoring biological mechanisms that may also mediate the transfer of toxic chemical such as PCBs in aquatic systems. Feeding behavior, which reflects the organism's position in the food chain and its habitat, constitute important factors influencing the PCB profile (Cakirogullari and Secer, 2011). Biotransformation of PCBs in animals can be explained as the ratio of a PCB concentration congener to that of a more persistent congener.…”

“…Synthetic organochlorines (OCs) such as DDTs, PCBs, HCHs, HCB, and chlordanes (CHLs) are highly persistent and lipophilic organic compounds that tend to bioaccumulate in fatty tissue of most organisms (Cakirogullari and Secer, 2011). Most of these compounds are highly resistant to degradation by biological, photochemical, or chemical methods (Ramu et al, 2007).…”

Organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) residues were studied in different mollusk species from the Egyptian Mediterranean and Red Sea coasts. The average levels of OCPs in mollusks comprised chlordanes, dieldrins, total endrin, endosulfan compounds, and methoxychlor (DECEM), dichlorodiphenyltrichloroethanes (DDTs), and, hexachlorocyclohexanes (HCHs). The averages of HCHs, DDTs, and polychlorinated biphenyls (PCBs) in mollusks from the Mediterranean Sea were 1.13±1.21, 1.30±1.27, and 1.40±0.93 ng/g, respectively; from the Red Sea, they were 0.62±0.90, 1.77±1.82, and 6.44±5.05 ng/g, respectively. The analysis of HCHs, DDTs, and PCBs in mollusks indicates a new usage of lindane, PCB congeners, and the input of technical HCH and aged DDT. The data showed that the Red Sea Coast was more affected by PCBs congeners than the Mediterranean Sea Coast, which may be attributed to the different activities along the two coastal areas. Mollusks in the Mediterranean Sea had higher dieldrins, total endrin, endosulfan compounds, and methoxychlor contents than those in the Red Sea. Interestingly, HCHs, DDTs, and PCBs levels were lower than those recommended for Swedish Food Regulation and U.S. Food and Drug Administration, which means that mollusks from these two coastal areas are safe as food.

“…En contraste, estos mismos autores reportaron valores menores de POC en el tejido muscular de los mismos organismos analizados; por ejemplo, el máximo fue de 16 ng/g para p,p'-DDE. El resto de los compuestos detectados tuvo concentraciones < 3.5 ng/g y la diversidad de plaguicidas también fue más baja, patrón que concuerda con lo reportado para otros estudios, lo cual demuestra una acumulación diferencial en los organismos (Boonyatumanond et al 2002, Cakirogullari y Secer 2011.…”

Palabras clave: contaminación, agroquímicos, riesgo, toxicidad, bioacumulación RESUMEN Se presentan las tendencias de los plaguicidas organoclorados (POC) en organismos costeros de México, principalmente los estudiados en el Golfo de México durante aproximadamente 20 años. Los peces, crustáceos y moluscos han sido los más evaluados debido a su gran demanda para consumo humano; las familias analizadas fueron Lutjanidae, Centropomidae, Scombridae, Cichlidae, Ariidae y Carangidae para peces, Portunidae y Penaeidae para crustáceos decápodos, y Ostreidae y Mytilidae para moluscos bivalvos. El método común ha sido el propuesto por UNEP/FAO/IOC/IAEA, que tiene buena detección y confiabilidad (límite de detección 0.01 ng/g peso seco; coeficiente de variación 3-15 %; recuperación 90-101 %). Los POC más frecuentes fueron β-HCH, lindano, aldrín, p,p'-DDT, p,p'-DDD, heptacloro, endosulfán α, β y su sulfato. Las concentraciones han variado desde < 1.0 hasta ~ 20 ng/g peso seco. Para el sulfato de endosulfán, las concentraciones han sido similares para los tres grupos biológicos evaluados, sin diferencias metabólicas significativas entre invertebrados y vertebrados, lo que puede significar la gran carga de residuos clorados que existe en los ambientes costeros donde fueron capturados y, por lo tanto, la exposición continua de la biota a estos xenobióticos. La mayoría de los POC reportados han sido prohibidos a nivel internacional y nacional; sin embargo, los datos señalan usos recientes de POC prohibidos como p,p'-DDT y lindano, probablemente debido a aplicaciones clandestinas y a la compra y venta ilegal vía países donde todavía se fabrican y por rutas vulnerables de fronteras con países en desarrollo como el nuestro, representando un gran riesgo para la salud humana debido a sus características tóxicas y cancerígenas.
