The combined pollution of microplastics (MPs) and arsenic (As) has gradually been recognized as a global environmental problem, which calls for detailed investigation the synergistic toxic effects MPs As on plants their mechanisms. Therefore, interaction between polystyrene (PS-MPs) arsenate (AsO43−) (in following text, it is abbreviated As(V)) its lettuce were investigated in this study. Firstly, chemisorption was identified main mechanism PS-MPs As(V) by analysis adsorption kinetics, thermodynamics, Fourier transform infrared spectroscopy (FTIR). At same time, addition promoted penetration through continuous endodermal region Casparis strip. Furthermore, compared with CK group, found that co-addition exacerbated lowering effect pH value rhizosphere environment inhibitory root growth. In P20V10 decreased 33.0%. Compared to P20, P20V1, chlorophyll content 68.45% (16 SPAD units), 71.37% (17.73 61.74% (15.36 units) length 19.31% (4.18 cm), 50.72% (10.98 47.90% (10.37 cm) lettuce. P5V10 increased CAT 153.54% (33.22 U·(mgprol)−1) 182.68% ((38.2 U·(mgprol)−1)), Ca 31.27% 37.68%, Zn 41.85% 41.85%, but presence reduced Na 22.85% (P5V1) 49.95% (P5V10). co-exposure significantly affected physiological biochemical indicators well nutritional quality Finally, metabolomic leaves showed metabolic pathways tricarboxylic acid cycle (TCA cycle), sulfur metabolism, pyruvate metabolism. This study provides data management measures As(V).
