“…Because the susceptibility to contaminants varies among species, tissue residue guideline (toxicity threshold) for the protection of wildlife consumers of aquatic biota for DDTs was calculated as 0.15-3.0 µg/g and for PCBs 0.11-0.48 µg/g [17]. Although the concentrations of many persistent organochlorine chemical residues have declined over the past two decades, our and others authors' results indicate that contaminant residues still remain a risk to piscivorous wildlife at some sites [4,12,17,18].…”

“…Es importante señalar que en el trabajo de Schmitt et al (2005) el muestreo se llevó a cabo durante los años 1997 y 1998. Una publicación de un muestreo efectuado en el año 2001 en Salton Sea, el lago más grande hecho por el hombre en California, USA, (Sapozhnikova et al, 2004) da valores menores que los encontrados en los pescados de la Presa Vicente Guerrero y del Río Grande para DDE y DDD totales en músculo de tilapia (4,6 a 21,4 y 0,5 a 2,2 ng/g, respectivamente). Los valores mayores encontrados en los pescados de la Presa Vicente Guerrero se pueden atribuir a que en Estados Unidos se prohibió el uso del DDT desde 1972.…”

“…OPs are used as alternative to their more persistent organochlorines counterpart; however there is growing concern about their longevity in the environment because of increased various environmental are present in environmental media, often well removed from the initial site of application with evidence that some of these chemicals long range transport and have been observed to be present in remote locations like Residues of these chemicals have been detected sediments and soil [9][10][11][12][13][14], atmosphere crops and surface waters [ [18] in homes in the US detected chlorpyrifos and diazinon in 78% and 35% respectively, of the samples collected, raising more concern about their fate and human exposure. Consequently, there is an urgent need to better understand their once released.…”
