From: The Mediterranean Plastic Soup: synthetic polymers in Mediterranean surface waters
PCA ordination based on the occurrence of the seven most common polymer typologies.
All 74 samples are plotted in relation to the first two principal components (PC1 and PC2). Orange dots represent Adriatic samples (n = 30) while western Mediterranean samples are in black (n = 44). Distance biplot of the eigenvectors (not in scale with data points) is shown to help with the interpretation of the loadings results.
