Method synopsis

Standardized collection of wet and dry atmospheric deposition samples using NADP Aerochem Metrics collectors to quantify microplastic fallout in remote areas.

Synthesized from method descriptions across 1 paper using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Plastic rain in protected areas of the United States (2020), Science. Implementations in other papers (listed below) may differ.

1. Sample collection setup
   Installed standardized National Atmospheric Deposition Program (NADP) Aerochem Metrics wet-dry collectors at each protected area sampling site. Used separate collection protocols for wet versus dry deposition.
   Quantities: 11 sampling sites across western United States protected areasDuration: Continuous deployment from late 2017 to early 2019Conditions: Remote protected area locations away from direct anthropogenic influence
   Equipment: National Atmospheric Deposition Program (NADP) Aerochem Metrics wet-dry collector
2. Wet deposition sampling
   Collected samples at week-long intervals while precipitation occurred. Samples were collected in specialized containers during rain/snow events.
   Quantities: 236 total wet deposition samples across all sitesDuration: Weekly collection intervals when precipitation occurredConditions: During precipitation events (rain or snow)
   Equipment: wet deposition collection containers
3. Dry deposition sampling
   Collected dry atmospheric deposition samples at monthly or bimonthly intervals during periods without precipitation.
   Quantities: 103 total dry deposition samples across all sitesDuration: Monthly to bimonthly collection intervals
