Oral: PDFAbstract
MICROPLASTICS (MPs)
-
Synthetic polymers derived from petroleum
-
Size: from 1 to 5000 μm
-
Shapes: spheres, films, fragments, and fibers
OBJECTIVES
-
Characterize the type of soil on the site
-
Characterize the MPs found in the soil and groundwater samples
-
Relate the occurrence of MPs with the physical characteristics of the environment
-
Discuss the potencial sources of MPs in the study area
STUDY AREA
Bauru River (Bauru City, State of São Paulo, Brazil):
-
Groundwater: public supply, but without sewage treatment
-
Historical contamination of groundwater by sewage
CONCLUSIONS
-
Microplastics were identified in soil and groundwater, predominantly in smaller sizes (0,063 to 1 mm)
-
Shapes: Groundwater: fibers > fragments, Soil: only fibers
-
Color: Saturated zone: Preponderance of colored fibers, Unsaturated zone: Preponderance of transparent fibers
-
Different sources of contamination for the unsaturated zone and saturated zone.
