| evaluation of potential relationships between chemical contaminants in sediments and aquatic organisms from the lower passaic river, new jersey, usa. | the lower passaic river, new jersey, usa, a tidal tributary to newark bay and part of the new york and new jersey harbor estuary, is contaminated with a variety of persistent organic pollutants (pops) due to nearly two centuries of heavy industrialization and urbanization. resident aquatic organisms are exposed to, and can bioaccumulate, a variety of chemical contaminants from sediments, water and other organisms. in the present study, the relationships between selected pops detected in both sur ... | 2011 | 21520249 |
| mercury in freshwater fish of northeast north america--a geographic perspective based on fish tissue monitoring databases. | as part of an initiative to assemble and synthesize mercury (hg) data from environmental matrices across northeastern north america, we analyzed a large dataset comprised of 15,305 records of fish tissue hg data from 24 studies from new york state to newfoundland. these data were summarized to provide mean hg concentrations for 40 fish species and associated families. detailed analyses were carried out using data for 13 species. hg in fishes varied by geographic area, waterbody type, and waterbo ... | 2005 | 15931965 |
| gizzard shad put a freeze on winter mortality of age-0 yellow perch but not white perch. | four decades of observations on the limnology and fishes of oneida lake, new york, usa, provided an opportunity to investigate causes of mortality during winter, a period of resource scarcity for most juvenile fishes, in age-0 yellow perch (perca flavescens) and age-0 white perch (morone americana). this time series contains several environmental (e.g., winter severity) and biological (e.g., predator abundance) signals that can be used to disentangle multiple effects on overwinter mortality of t ... | 2006 | 16937813 |
