To minimize potential cross-contamination, measures recommended by[68], were adopted and adapted throughout all stages of the study, including collection, sorting, processing, and sample analysis.
All materials employed were made of glass or aluminum, and 100% cotton lab coats were worn to avoid the release of synthetic fibers and sample contamination.
Personnel movement within the laboratory was restricted during filtration processing and visual analysis of samples. Additionally, containers filled with bi-filtered water were individually exposed during collection, sorting, and processing, serving as atmospheric contamination controls for each stage; these controls were subsequently filtered and analyzed in the same manner as the other samples. If particles were detected in these controls, the corresponding number was subtracted from the MP quantification of processed samples, considering particle characteristics such as color and shape[68].
