“…The decreasing concentration of CHL in mussels downstream of the oligotrophic Lake Taupo is associated with eutrophication indicated by a 7-fold increase in chlorophyll a concentrations (Huser and Wilson 1995) and subsequent increase in mussel condition (Roper and Hickey 1994), which results in the observed inverse relationship. Interestingly, unlike an earlier reported study (Galindo-Beet and Flores-Baez 1991), there was only a weak relationship between the percentage lipid content of the mussels (Table 4) and total DDT levels (n=8 r=0.64, P=0.09). Roper and Hickey (1994) The relationship between lipid and condition measurements showed contrasting responses between sites for H. menziesi in this study.…”

“…The highest total DDT value in sediments collected in both areas during the same period was 16.4 ng/g dry weight (dw) [46], about three times less of what was reported for sediments off the San Diego coast in 1971 [47]. Total DDT (85% p,pЈ-DDE) concentrations were also low (range ϭ 11-58 ng/g ww) in mussels collected during 1984 at the Punta Banda estuary near Ensenada, Baja California [48].…”

Abstract-The hypothesis that migratory birds accumulate persistent organochlorine pesticides (POPs) during the winter in Latin America has been prevalent for many years, particularly since 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane (DDT) was banned in the United States in 1972. It has been suggested that peregrine falcons (Falco peregrinus), black-crowned night herons (Nycticorax nycticorax), white-faced ibises (Plegadis chihi), various migratory waterfowl and shorebirds, and other avian species accumulate higher concentrations of POPs while on migration or on their wintering grounds in Latin America. Nonetheless, the data obtained thus far are limited, and there is no clear pattern to suggest that such accumulation occurs on a widespread basis. In this review wildlife contaminant studies conducted along the U.S.-Mexico border and throughout Mexico are discussed. The results for the most part seem to indicate that no major accumulation of 2,2-bis(p-chlorophenyl)-1,1-dichloroethylene) (DDE), the most persistent organochlorine compound, has occurred or been reported for most parts of Mexico. The majority of the DDE values in birds from Mexico were similar to those reported in birds from the southwestern United States during the same years. More work needs to be done, particularly in those cotton-producing areas of Mexico where DDT was applied heavily in the past (e.g., Chiapas and Michoacan). Because DDT is still used for malaria control and may still be used in agriculture in Chiapas, this state is probably the one where most migrant species would still be at a significant risk of increased accumulation of DDE and DDT.

“…Data from the present study seem corroborating the downwards trend of contamination of the aquatic environment in Abidjan by DDT. However, as suggested by Benbakhta the presence of DDD in all fish species collected in the markets of Abidjan originates from an ancient contamination with DDT, which gradually breaks down into DDD [19,25,26].…”
