Accumulation of plastics in plants under different exposure conditions.

Plants	Plastic Types	Time (Days)	Media	Accumulation	Reference
Z. mays	PS (NH2, COOH)	28	Soil	Both types of plastic accumulate in leaves and further transport to the roots.	[46]
L. sativa	PS NPs (0.1 and 1 mg L−1)	35	Soil	NP uptake by plant leaves by stomata and translocation downwards to the plant.	[47]
C. sativus	PS (100, 300, 500, 700 nm)	65	Hydroponics	PS uptake by the root and future transport to the leaves, flower, and fruit through the stem.	[42]
A. cepa	PS (0.01, 0.1, 1 g L−1)	72 h	Hydroponics	PS enters different cellular compartments.	[44]
A. thaliana	PS (SO3H, NH2)	35	Soil	Positive-charge NPs have a great effect on the root and their uptake and internalization as compared to negative-charge particles.	[40]
T. aestivum, L. sativa	NPs 0.2 and 2 μm	20 10	Sandysoil, hydroponics	PS enters the root through crack-entry mode and through transpiration, which pulls PS transport from root to shoot.	[41]
L. sativum	MPs and NPs (103–107 P mL−1)	72 h	Filter paper	Microplastic accumulates in the pores of the L. sativum seed and delays germination.	[49]
