Pyrethroids in Southern California coastal sediments.
Little is known about pyrethroid fate and effects in estuarine and marine environments. In the present study, the extent and magnitude of pyrethroids in coastal embayments of the Southern California Bight (SCB), USA, were assessed. Using a stratified probabilistic design, 155 sediment samples were collected from four embayment habitats (estuaries, marinas, open bays, and ports) and analyzed for...
متن کاملAnalysis of Endocrine Disruption in Southern California Coastal Fish Using an Aquatic Multispecies Microarray
BACKGROUND Endocrine disruptors include plasticizers, pesticides, detergents, and pharmaceuticals. Turbot and other flatfish are used to characterize the presence of chemicals in the marine environment. Unfortunately, there are relatively few genes of turbot and other flatfish in GenBank, which limits the use of molecular tools such as microarrays and quantitative reverse-transcriptase polymera...
متن کاملSupplemental Material: Analysis of Endocrine Disruption in Southern California Coastal Fish Using an Aquatic Multispecies Microarray
Estradiol and 4-nonylphenol exposure studies in zebrafish. Approximately eighty male zebrafish were divided evenly between three 80 L glass aquaria. Each aquarium was individually heated to maintain a temperature of 26 /29 °C with a light-dark cycle ratio of 14:10 h. Fish were acclimated for one week prior to commencing the experiment. One tank contained only tap water (negative control) and th...
متن کاملUsing Stable Isotopes
Introduction Direct measurement of de novo lipogenesis has not previously been possible in humans. We measured de novo hepatic lipogenesis in normal men by means of stable isotopes and by combining the acetylated-xenobiotic probe technique with mass isotopomer analysis of secreted very low density lipoproteinfatty acids (VLDL-FA). Sulfamethoxazole (SMX) was administered with ['3Clacetate during...
