Among the different sampling methods, what can be used as the most efficient method to sample surface water and the sediments of a river in microplastics analysis?
Shaahin Nazarpour Tameh
The goals of the research and the features of the river system determine the most effective sample strategy, hence there is no "best" strategy. Sediment grabs, plankton net tows, and passive collecting devices are frequently employed to sample microplastics in surface waters and sediments. Factors including sample goals, circumstances, feasibility, and available resources should be taken into account while determining the best approach to take. It's possible that characterizing microplastics in various matrices requires a mix of techniques.

- Surface Water: Use nets, pumps, or passive samplers for surface microplastics.
- Sediment: Collect sediment cores or grab samples from the riverbed.
- Combined: Consider combining surface and sediment sampling.
- Size: Use filters or density separation to focus on specific microplastic sizes.
- Quality Control: Include blank and control samples to catch contamination
