[eng] Coastal ecosystems are continuously affected by anthropogenic threats such as
urbanization, maritime activities, recreational and commercial activities, all of which have
been prominent sources of plastic marine litter. During summer of July 2017, the spatial
distribution of floating plastics at seven locations across the island using nearshore sea
cleaning boats was assessed. One-hundred percent of the samples contained plastic
items of varying sizes, ranging from macro- (> 25 mm), meso- (5-25 mm) and microplastics (< 5 mm), composed principally of fragments, films and filaments. Significant
differences were found for the abundance and size differences of items between the
sampling locations. All samples were collected within one kilometre of the coastline and
both the abundance and weight was found to significantly increase closer to the
coastline. Plastics smaller than 5 mm were the dominant size class and fragments
composed of almost 60% of the items with the main colors being transparent and white.
Low variability of polymers were found with polyethylene being the primary plastic
polymer type. These preliminary results indicate there is high small scale variability of
coastal marine plastic concentrations surrounding the Balearic Islands |
