Global Acid Mine Drainage Microbial Abundance and Environmental Data

800 acid mine drainage-related samples, including water, tailings, sediment, and biofilm, were compiled from global sites over the past two decades. The dataset contains 16S rRNA sequencing data on Acidithiobacillus abundance and corresponding physicochemical parameters for each sampling site. It supports analysis of environmental drivers, such as CO2 and heavy metals, on microbial distribution in mining-impacted ecosystems.

Use Cases

• Modeling Acidithiobacillus abundance based on physicochemical parameters like CO2 and heavy metals.
• Analyzing global distribution patterns of acidophilic bacteria across different sample matrices (water, sediment, biofilm).
• Investigating temporal trends in microbial metal mobilization across two decades of sampling.
• Correlating environmental site data with 16S rRNA sequencing results from acid mine drainage samples.

Strengths

• Contains data from 800 globally sourced samples with detailed breakdown by matrix type (220 water, 195 tailings, 280 sediment, 105 biofilm).
• Includes corresponding physicochemical parameters for each site, extracted directly from literature.
• Covers a temporal dimension of approximately two decades, allowing for time-series analysis.

Limitations

• Column names and exact data structure are not provided in the available metadata.
• The exact row count is not specified, and the dataset size is only given in bytes.
• Relies on data digitized from figures in literature, which may introduce measurement error.
