Concentration limits for XAS experiments performed on FAME in the biological (open symbols) and environmental (solid symbols) science fields as reported in the literature. The amounts correspond to µg g−1 (name of the element in bold) or µM l−1 (italic). These experimental concentration limits are obtained during EXAFS studies except for the Se, V and two of the Cr experiments (Chaurand et al., 2007; Rose, Cornu et al., 2007; Gouget et al., 2005; XANES studies). Open circles: Bakkaus et al. (2009) (vegetal). Open up-triangles: Chaurand et al. (2007) (slag). Open down-triangles: Carrière et al. (2006) (biological). Filled down-triangles: Collins et al. (2006) (soil). Filled circles: Doelsch et al. (2006) (soil). Filled up-triangles: Froideval et al. (2006) (Al hydroxide). Open squares: Gouget et al. (2005) (biological). Open diamonds: Kirpichtchikova et al. (2006) (soil). Filled diamonds: Manceau et al. (2005) (clay). Crosses (×): Manceau et al. (2007) (Fe–Mn coatings). Plus signs (+): Rose, Bergé-Lefranc et al. (2007) (biological). Filled squares: Rose, Cornu et al. (2007) (cement). Asterisks: Takahashi et al. (2007) (Fe–Mn oxides). |
