| accumulation of metals in fish from lead-zinc mining areas of southeastern missouri, usa. | the potential effects of proposed lead-zinc mining in an ecologically sensitive area were assessed by studying a nearby mining district that has been exploited for about 30 yr under contemporary environmental regulations and with modern technology. blood and liver samples representing fish of three species (largescale stoneroller, campostoma oligolepis, n=91; longear sunfish, lepomis megalotis, n=105; and northern hog sucker, hypentelium nigricans, n=20) were collected from 16 sites representing ... | 2007 | 17306371 |
| mercury bioaccumulation and biomagnification in ozark stream ecosystems. | crayfish (orconectes spp.), asian clam (corbicula fluminea), northern hog sucker (hog sucker; hypentelium nigricans), and smallmouth bass (smallmouth; micropterus dolomieu) from streams in southeastern missouri (usa) were analyzed for total mercury (hgt) and for stable isotopes of carbon (δ¹³c), nitrogen (δ¹⁵n), and sulfur (δ³⁴s) to discern hg transfer pathways. hgt concentrations were generally lowest in crayfish (0.005-0.112 μg/g dw) and highest in smallmouth (0.093-4.041 μg/g dw), as was δ¹⁵n ... | 2011 | 21868094 |
