  1. Ion intensity (average counts) in the different plastic membranes polyethylene napthalate (PEN), polyethylene terephthalate (PET), polyphenylene sulphide (PPS) and polyester (POL). The plastic membranes were analyzed by LA-ICP-MS, and data represent the average ion intensities ± SE from a 300 × 300 µm square (n.d. = no signal detected)
