DATA & FILE OVERVIEW
---------------------
1. File List
   A. Filename:   Nanoplastic Growth Based Viability Assay Raw Data Combined     
      Short description:  optical density measurements of Shewanella oneidensis grown under different conditions (aerobic vs anaerobic) with varying exposure doses to nano-polystyrene particles.      
        
   B. Filename:    Nanoplastic ICP MS Raw Data    
      Short description:  Mass spectra quantified amounts (in ppm) of Pd, that was used as a label in nano-polystyrene. 

   C. Filename:    Archived Raw Data.zip   
       Short description: Includes Nanoplastic ICP MS Raw Data and Nanoplastic Growth Based Viability Assay Raw Data Combined in .csv for archival purposes.

2. Relationship between files:        
Files represent 2 different types of measurements on our samples. Samples were bacteria exposed to different concentrations of nano-polystyrene.

--------------------------
METHODOLOGICAL INFORMATION
--------------------------
1. Description of methods used for collection/generation of data: 
UV-visible spectroscopy was used to collect growth based viability data and ICP-mass spectrometry was used to collect ICP-MS data.

2. Methods for processing the data: <describe how the submitted data were generated from the raw or collected data>
Viability data was calculated from growth curves with an R algorithm (see published paper supporting information for code). Additionally, calibration curves generated with standards were used to calculate concentrations.

3. Instrument- or software-specific information needed to interpret the data:


4. Standards and calibration information, if appropriate:
Discussed in published peer-reviewed article.


5. Environmental/experimental conditions:
Shewanella oneidensis were exposed to nano-polystyrene particles (at concentration of 0-300 mg/L) in aerobic and anaerobic conditions. 

6. Describe any quality-assurance procedures performed on the data:


7. People involved with sample collection, processing, analysis and/or submission:
Victoria Fringer, Liam Fawcett, Denise Mitrano, and Melissa Maurer-Jones
