| evaluation of two quantitative pcr assays using bacteroidales and mitochondrial dna markers for tracking dog fecal contamination in waterbodies. | this study describes a comparative performance evaluation of two qpcr assays targeting a dog-associated bacteroidales 16s rrna genetic marker (canbac-ucd) and a dog mitochondrial dna (mtdna) marker. the same fecal and environmental samples were assayed for the two markers thereby allowing direct comparison. a wide range of non-target species including, human, pig, horse, deer, mountain goat, bison, caribou, and moose were tested. marker persistence was also monitored in freshwater microcosms. bo ... | 2012 | 23041493 |
| transfer factors and effective half-lives of (134)cs and (137)cs in different environmental sample types obtained from northern finland: case fukushima accident. | the fukushima npp accident caused a small but detectable cesium fallout in northern finland, of the order of 1 bq/m(2). this fallout transferred further to soil, water, flora and fauna. by using modern hpge detector systems traces of (134)cs from the fukushima fallout were observed in various samples of biota. in northern finland different types of environmental samples such as reindeer meat, berries, fish, lichens and wolf were collected during 2011-2013. the observed (134)cs concentrations var ... | 2015 | 25935505 |
| polychlorinated biphenyls (pcbs) and polybrominated biphenyl ethers (pbdes) in environmental samples from ny-ålesund and london island, svalbard, the arctic. | polychlorinated biphenyls (pcbs) and polybrominated biphenyl ethers (pbdes) were determined in environmental samples collected from ny-ålesund and london island, svalbard, the arctic. total pcb concentrations (∑25pcbs) varied from 0.57 to 2.52 ng g(-1) dry weight (dw) in soil, 0.30 to 1.16 ng g(-1) dw in plants and 0.56 to 0.98 ng g(-1) dw in reindeer dung. the non-aroclor congener of cb-11 was predominant in most samples compared to other congeners, accounting for 16.0±9.8% to the ∑25pcbs. the ... | 2015 | 25697952 |
| distribution and transfer pattern of polychlorinated biphenyls (pcbs) among the selected environmental media of ny-ålesund, the arctic: as a case study. | polychlorinated biphenyls (pcbs) were analyzed in multi-environmental samples collected from ny-ålesund, the arctic to explore their legacy and transfer patterns. pcbs were ubiquitously in the environmental media, within the ranges of 1.73-6.27 and 9.18-141.1 pg m(-3) in vapor and aerosol, 2.76-10.8, 3.09-8.32, 22.5-56.3, 35.4-51.4 and 31.8-39.6 ng g(-1) (dry weight) in soil, sediment, plant, bird guano and reindeer faeces, respectively. the spatial distribution patterns exhibited a general sout ... | 2014 | 25444625 |
| mineral licks as environmental reservoirs of chronic wasting disease prions. | chronic wasting disease (cwd) is a fatal neurodegenerative disease of deer, elk, moose, and reindeer (cervids) caused by misfolded prion proteins. the disease has been reported across north america and recently discovered in northern europe. transmission of cwd in wild cervid populations can occur through environmental routes, but limited ability to detect prions in environmental samples has prevented the identification of potential transmission "hot spots". we establish widespread cwd prion con ... | 2018 | 29719000 |
