Optical Characteristics. The value of SUVA for water samples of the Vostochniy watershed profile ranges from
Optical Characteristics. The color of filtrates and ultrafiltrates progressively decreases from the 100 µm to 1 kDa fraction as it is illustrated for sample of soil solution (OR-9) in Fig. 2.10. Similarly, the SUVA reflecting the degree of hydrophobicity and aromaticity significantly increases (by a factor of 10) with the decrease of the pore size in soil solution OR-9; this increase is much smaller in the low feeding lake OR-2 (a factor of 2.5) and it is the minimal (≤ 30%) in the stream OR-1 and the terminal clearwater lake OR-8 (Fig. 2.11 A, B). These observations suggest that the transformation of DOM via microbial- and photo-degradation, much more pronounced in large lake and spring water compared to the soil solution, is capable homogenizing the distribution of hydrophobic/aromatic carbon among different size fractions presumably via decreasing the proportion of this fraction in the LMW colloidal pool. This pool is most labile and thus most susceptible to the degradation. The ratio of the light absorbencies in UV/visible range may help to reveal the basic features of OM chemical and source-related fractionation among different filtrates and ultrafiltrates. For example, the ratio of E254 to E365 was used as a surrogate for DOM average molecular weight, with samples with relatively lower ratios having relatively higher molecular weight DOM (Xxxxxxxxxx et al., 1997; Xxxxxxx et al., 2003; Xxxxxxx-Xxxx et al., 2008; Xxxxxxxx et al., 2007; Xxx et al., 2011). However, in studied boreal waters, the E254/E365 parameter remains rather constant (typically between 4.5 and 5.5) and does not subject to variations between µm and kDa filtrates and ultrafiltrates (not shown). Xxxxxxx et al. (2003) have calculated the value E254/E365 close to 4 in all water samples from the lake indicating the fulvic nature of the dissolved organic carbon. In Peuravuori et al. (1997) the values 4.52 and 5.72 of parameter E2/E3 correspond to number-average molecular weight of 3380 and 1120, respectively for the humic solutes in whole-water samples. Similarly, the absorbance ratio of E280/E350 which may approximate the aromatic carbon content of DOM (Xxxxx et al., 2000) exhibit very constant distribution among different size fractions, slightly increasing in the < 1 kDa ultrafiltrates (see Table ESM-2.2). An alternative parameter helping to estimate the relative composition of autochthonous versus terrestrial DOM is the absorbance ratio E254/E436 (Xxxxxx, 1998; Xxxxx, 2004; Xxx et al., 2006).
