F CO 2 increased significantly with decreasing DO, chlorophyll- a (Chl- a ) and 未 2 H-H 2 O, while F CO 2 increased with increasing specific UV absorbance (SUVA 254 ) and a terrestrial humic-like component (C2). We found that DO concentration and pH declined with increasing ...
Thus, variations in the covalent component for the Si–O bonds amongst different silicates would influence their homolysis rates and SBR densities. To evaluate the homolysis rates of Si–O bonds in silicates, an energetic statistical approach—the Boltzmann Distribution—was employed to quantify the ...

Subtracting out the biodegradation component for Lacawac (5.6 mg L−1) from the photodegradation end results (39.0 mg L−1) indicates that a minimum of 45% of the tDOC pool was photodegraded in the long-term experiment. In the short-term experiments, we observed similar trends compared ...

The mineral association may also explain the greater resistance to degradation of this terr-OC component. In contrast, more amorphous humic-like and low-density terr-OC from surface soil and recent vegetation represents a younger but more bioavailable and thus degraded terr-OC component held buoyant...
Compared with forested land, urbanized land clearly produced runoff GRSP with low molecular weight and aromaticity, as well as more degradation of humic-like materials (C3 component). The highest GLM explaining 89% of the variables, including significant variables (p < 0.05) such as microbial ...
approximately 60% of which are accessible to microbial utilization in less than 5 days. A 56-day incubation suggested that microplastic leachates had higher degradability than riverine humic acid (Zhang et al.2022). Thus, it is plausible to speculate that microplastic leachates may have a vital...
