Microplastic pollution in soils and surface waters is a growing environmental concern, yet the mechanisms governing transport by overland flow remain unclear. This study investigated influence of soil texture slope gradient on movement microplastics with different shapes polymer compositions under simulated rainfall typical agricultural conditions semi-arid climate. Small flumes were subjected to controlled simulations replicating rain patterns, microplastic was quantified using collection flasks. The results indicated that neither nor significantly affected total transport. However, fibres exhibited greater retention compared other shapes. Polymer composition did not play major role mobility, except for polystyrene pellets, which transported more readily than polyethylene pellets. Field observations history sludge application confirmed predominance topsoil, reinforcing tendency this shape resist mobilisation. These findings suggest runoff primarily governed particle buoyancy rather properties or inclination. Future research should explore roles size, intensity, organic matter content mobility natural field conditions.

Detection of light ellipticity is crucial importance for target imaging and recognition in complex scenarios. However, it has been challenging to achieve one-shot detection by a single conventional optoelectronic device, due coupling between intensity polarization. Here, we realize using four-terminal valley Hall device based on monolayer MoS2 quantum material. The can decouple the elliptical polarization enable simultaneous photoconduction effects. We show that be directly detected measuring resistance which defined as ratio voltage photocurrent. Furthermore, demonstrate our proposed approach used detecting microplastics present soil at higher precision than approaches. Our work highlights potential exploiting unique properties 2D materials multi-dimensional perception optical information.
