INITIATIVES
RESULTS AND DISCUSSION
The mean concentration of mesoplastic and microplasticvaried from 2 to 43.3 particles m¯² and 0 to 104 particles m¯²,respectively, and size varied from 0.11 to 10.4cm (Fig 2).

CLASSIFICATION OF PLASTIC MATERIAL

Figure 2. Size of items collected in the High Water Line (HWL) and Backshore (BS)
The global demand for plastics has consistently increased over the past
few years.
Is currently around 322 million tons per
year³.
Being present in almost every product
of modern society.
And the plastic material is an environmental
problem of increasing concern.
INTRODUCTION
OBJECTIVE
This study aimed to characterize, quali and quantitatively,mesoplastics (5 – 25mm) and microplastics (<5mm) on threedifferent beaches in Santa Catarina Island, SC, Brazil
STUDY AREA
Fishing and mariculture activities, evidenced mainly in Ribeirãoda Ilha beach, an important Brazilian center for bivalveproduction4.
Beach users activities (locals and tourists), since Tourism playsan important role in Santa Catarina Island’s economy.
Oceans’ currents and surface winds also contribute to anexpressive number of pellets and fragments, brought to theisland, since the island has no sources of pellets.
Plurality of sources.
The plurality of marine litter shows that different sources needdifferent approaches to reduce them. These include changesin policy, local actions, improvement in waste-managementsystems and eliminating particularly items products. In thecase of Santa Catarina Island still has a lot to do since themunicipality of Florianopolis still requires that beach vendorsoffer to their clients only disposable utensils and straws,individually wrapped and sealed, and Florianópolis WasteManagement Plan still is not responsible for fishing relatedlitter.
