There are no data on potassium extraction from tobacco; however, a study of the extraction of a range of snus constituents by users showed that ~ 30% of the sodium content was extracted [16].
In this paper, we will present new data on the extraction of boron-containing clusters with a Source of Negative Ions by Cesium Sputtering.
Data on the extraction of metals and non-metallic industrial minerals was obtained from the United States Geological Survey (USGS, 2013).
This applies especially to data on timber extraction from home gardens and other private lands and survey of private saw mills.
Data on the extraction of fossil energy carriers (lignite and hard coal, petroleum, natural gas, peat) was derived from the energy statistics of the UN Statistics Division (UNSD, 2013).
Based on the standardized methodological framework of economy-wide material flow accounting (Eurostat, 2007; OECD, 2008a; Fischer-Kowalski et al., 2011), we have compiled data on used extraction and on imports and exports of materials.
We compiled data on domestic extraction, imports, and exports for the years 1950, 1960 19622), 1970 , 1980 , 19902000, 2005, and 2010 for 177 countries mostly based on international statistical sources; in some cases national data were used to fill gaps.
Methodology and data on micronutrient extractions are also presented to verify extractor performance.
A Corbett Rotor-Gene 6000 (QIAGEN) and Corbett software 24 series 1.7 were employed in the UK for rt-PCR and data analysis on extractions of NWs and NP eluates.
In addition, one reviewer (IV) extracted data from the included studies and documented these data on a data extraction sheet.
