Killin LO, Starr JM, Shiue IJ, Russ TC.
PMID: 27729011
BMC Geriatr. 2016 Oct 12;16(1):175. doi: 10.1186/s12877-016-0342-y.

BACKGROUND: Dementia risk reduction is a major and growing public health priority. While certain modifiable risk factors for dementia have been identified, there remains a substantial proportion of unexplained risk. There is evidence that environmental risk factors may explain...

McKee LJ, Bonnema A, David N, Davis JA, Franz A, Grace R, Greenfield BK, Gilbreath AN, Grosso C, Heim WA, Hunt JA, Leatherbarrow JE, Lowe S, Pearce SA, Ross JRM, Yee D.
PMID: 28672237
Sci Total Environ. 2017 Dec 15;605:482-497. doi: 10.1016/j.scitotenv.2017.04.203. Epub 2017 Jun 30.

Urban watersheds are significantly anthropogenically-altered landscapes. Most previous studies cover relatively short periods, without addressing concentrations, loads, and yields in relation to annual climate fluctuations, and datasets on Ag, Se, PBDEs, and PCDD/Fs are rare. Intensive storm-focused sampling and...

Wet-milling protocol was employed to produce pressed powder tablets with excellent cohesion and homogeneity suitable for laser ablation (LA) analysis of volatile and refractive elements in sediment. The influence of sample preparation on analytical performance was also investigated, including...

Trace elements in coconut water-a preliminary study.

Environmental geochemistry and health

Prasad EA, Raghul V.
PMID: 24197035
Environ Geochem Health. 1994 Jun;16(2):76-8. doi: 10.1007/BF00209828.

Trace element analysis for five elements namely, Ba, Sr, Mn, Cr and Cd was carried out on both ash weight and dry weight basis for mine water and coconut water from Mangampeta barite area. The concentration of trace elements...

Optimized elemental analysis of fluorescence lamp shredder waste.

Talanta

Hobohm J, Kuchta K, Krüger O, van Wasen S, Adam C.
PMID: 26592653

Fluorescence lamps contain considerable amounts of rare earth elements (REE). Several recycling procedures for REE recovery from spent lamps have been established. However, despite their economic importance, the respective recycling is scarce so far, with an REE recovery rate...

Trace elements and organochlorines in surf scoters from San Francisco Bay, 1985.

Environmental monitoring and assessment

Ohlendorf HM, Marois KC, Lowe RW, Harvey TE, Kelly PR.
PMID: 24233749
