Gallo-Reynoso JP, TB Malek, J García-Hernández, L Vázquez-Moreno, I Segura-García. 2014. Concentrations of DDE in blubber biopsies of free-ranging long-beaked common dolphins (*Delphinus capensis*) in the Gulf of California. Bulletin of Environmental Contamination and Toxicology. DOI 10.1007/s00128-014-1414-3 Abstract Long-beaked common dolphins (Delphinus capensis) in the Gulf of California have been exposed to persistent contaminants that originated in large agricultural areas near the coast. Live common dolphins were sampled by remote dart biopsies to determine concentrations of tDDT in blubber. Life stage and initial gender identification was determined by field observations. Gender was confirmed by genetic analysis of the skin. Concentration of tDDT in blubber was analyzed by gas chromatography. The 16 samples collected consisted of: 2 adult males, 6 adult females, and 8 juveniles. 4,40-DDE was detected in most of the samples with 4,40-DDD and 4,40-DDT under detection levels. Concentrations of DDE varied from nondetectable to 87.3 lg/g lipid weight with a median of 16 lg/g lipid weight. The highest concentration was detected in an immature female. No differences were detected between gender or life stage but this could be attributed to small sample size. We recommend continued sampling of D. capensis blubber biopsies from the Gulf of California in order to relate these levels with affected in vitro biomarkers such as mixed function oxidase activity.
