| fish consumption and pcb-associated health risks in recreational fishermen on the james river, virginia. | consumption of sport-caught fish contaminated with high levels of polychlorinated biphenyls (pcbs) may pose human health risks. to obtain estimates of fish consumption and fishing behaviors in recreational fishermen in virginia, on-site interviews (n=143; 134 men and 9 women) were conducted at seven public boat landings along the james river. using existing pcb concentration data from james river fish tissue samples collected from 1997, and 1999 to 2001, default and point estimates were calculat ... | 2008 | 18395199 |
| use of the p,p'-ddd: p,p'-dde concentration ratio to trace contaminant migration from a hazardous waste site. | for approximately 50 years, beginning in the 1920s, hazardous wastes were disposed in an 11-hectare area of the marine corps base (mcb) quantico, virginia, usa known as the old landfill. polychlorinated biphenyls (pcbs) and ddt compounds were the primary contaminants of concern. these contaminants migrated into the sediments of a 78-hectare area of the potomac river, the quantico embayment. fish tissue contamination resulted in the mcb posting signs along the embayment shoreline warning fisherme ... | 2006 | 16758288 |
| exposure to the cyanotoxin microcystin arising from interspecific differences in feeding habits among fish and shellfish in the james river estuary, virginia. | the cyanotoxin, microcystin (mc), is known to accumulate in the tissues of diverse aquatic biota although factors influencing exposure, such as feeding habits and seasonal patterns in toxin production, are poorly known. we analyzed seasonal variation in the mc content of primary and secondary consumers, and used dietary analysis (gut contents and stable isotopes) to improve understanding of cyanotoxin transport in food webs. periods of elevated toxin concentration were associated with peaks in t ... | 2014 | 24694322 |
