This document defines methods that measure amounts of bacterial cells or a marker gene DNA to obtain the total abundance in environmental aqueous samples, such as seawater and river water, for biodegradability assessment. Amounts of a marker gene DNA enable to give a prediction of abundance of bacterial cells by using a conversion factor such as average number of the marker gene homologues in a bacterial cell. The methods could be also applicable to aqueous samples artificially enriched with bacterial cells released from environmental sediments. In addition, this document is applicable to solution with bacteria extracted from environmental sediments and plastic surfaces, where appropriate pre-treatment might be defined elsewhere. In the document, the method provides measurement of prokaryotic bacterial cells, though eukaryotic microorganisms are out of scope.

NOTE   Eukaryotic microorganisms, especially fungi, are well known to be primary decomposers in land, but the role in hydrosphere has been less documented and is largely unknown yet. Actually, the proportion of fungi in the ocean whole microbial metagenome has been reported as low (fungal reads make up 1,4 % to 2,9 % [2]).

This document defines a list of cross-cutting terms commonly used in the field of carbon dioxide capture, transportation and geological sub-surface storage including through storage in association with enhanced oil recovery (EOR) operations. This document only deals with CO2 geological sub-surface storage. The terms are classified as follows: — general terms and definitions relating to carbon dioxide; — general terms and definitions relating to carbon dioxide capture, transportation and storage; — general terms and definitions relating to monitoring and measuring performance in carbon dioxide capture, transportation and geological storage; — general terms and definitions relating to risk; — general terms and definitions relating to relationships with stakeholders; A list of the main acronyms used is given in Annex A.
