Introduction Engineered nanomaterials（ENMs）are generally regarded as man-made materials with at least one dimension below 100 nm.
ENMs can be divided into four different classes： • carbon-based materials（e.g., fullerenes）, • metal-based materials（e.g., gold or TiO2 NPs）, • dendrimers（e.g., nano-sized polymers）, and • composites（i.e., mixtures of NPs）.
Testing the toxicity of NMs Materials that damage DNA can cause human cells to mutate, which can eventually lead to cancer.
This indicates there is little potential to cause lung disease in people working with these materials.
Although certain industrial uses of ENPs are covered under existing regulation, there are currently no specific regulations designed for these materials in the world.

The thin wall material is F313, substrate material is 45 steel.

Because the acid wastewater goes into the weak structural plane, reacting with the constitutional materials and fillings in slopes, the react change the microstructure of the rock and soil, and replace, dissolve the components, causing the cohesion and internal friction angle of slope reducing eventually and slope failure.
Therefore, the instability mechanism of soil-like slopes along the weak structural plane mainly lies in the acid mine drainage go into the weak structural plane, react with the constitutional materials and fillings in slopes, the react change the microstructure of the rock and soil , and replace, dissolve the components.
