Determination of photosynthetic activity by duckweed (Spirodela polyrhiza) exposed to 50nm and 500nm plastic particles in concentrations of 102, 104 and 106 particles mL-1 for 120 hours. The photosynthetic activity, which was measured through chlorophyll contents, of the exposed duckweed was compared to non-exposed control organisms, with 3 replicates per treatment. The experiment measured the endpoints of chlorophyll a, chlorophyll b and total chlorophyll contents after 120 hours, employing spectrophotometrical determination of absorbance.
