Description
897 days of laboratory incubation data track soluble, adsorbed, and organically bound 99Tc concentrations in 20 topsoils from central England. The dataset quantifies transformation kinetics as a function of soil properties like pH and organic matter content across arable, grassland, and moorland/woodland land uses.
Use Cases
Model long-term 99Tc bioavailability in aerobic soils using soluble, adsorbed, and organically bound concentration measurements.
Analyze transformation kinetics of 99Tc as a function of soil properties such as pH and organic matter content.
Compare 99Tc behavior across different land use categories (arable, grassland, moorland/woodland).
Study the temporal evolution of 99Tc speciation over the 897-day incubation period under controlled 10°C conditions.
Strengths
Long-term temporal data covering 897 days (2.5 years) of controlled incubation.
Experiment uses 20 distinct topsoils with contrasting properties and land uses.
Data quantifies three specific chemical fractions: soluble, adsorbed, and organically bound 99Tc.
Limitations
Limited to 20 soil samples from central England, reducing geographic generalizability.
Laboratory-controlled conditions (10°C, dark, moist aerobic) may not fully replicate field environments.
Specific column names, row counts, and sample data are unavailable for detailed structural assessment.
