Transport and vehicle traffic are closely connected with particulate matter (PM) pollution, inducing various fractions into the atmosphere, some of them forming significant deposits on surface car. They washed away during carwash-inducing slurries collecting PM deposits, which characteristic a large area. Crystalline was investigated by XRD coupled polarized optical microscopy (POM). Organic matters were Fourier-Transform Infrared spectrometry (FTIR) gas chromatography, GC-MS. Their microstructure elemental composition SEM-EDX. The crystalline features contain mainly quartz, calcite, clay (muscovite kaolinite) particles having traces goethite lepidocrocite. Slurry particle size distribution established sieving following meshes: 63 µm, 125 250 500 1000 2000 4000 µm. Coarse 250–4000 μm dominated quartz calcite particles. amount decreases size, while muscovite kaolinite increases in finest 0–125 μm. evidenced, firstly, FTIR spectroscopy, revealing mostly CH2; C=O, NH4 bonds that more intense for fine fractions. organic form amorphous crusts associated micro- nano-plastic related to phthalates washing detergents. Atomic Force Microscopy revealed their range between 60 90 nm evidenced nanoparticles within samples. nanofractions adhere bigger humid environments, assuring immobilization reduce hazardous potential. Carwash slurry blending fertile soil ensures proper grass seed germination growth at mixtures up 60% slurry, allowing its sustainable reconversion as landfill dump rehabilitation, preventing emission hazard. Blended compositions containing than have noxious effects seeds, inhibiting germination.
