In foreign countries, the researches in fields with respect to heavy metal in soil of shooting range, including environmental chemistry (Xifra, Knechtenhofer et al. 2002; Cao, Ma et al. 2003; Klitzke and Lang 2009) and environmental risk analysis (Lewis, Poppenga et al. 2001; Mozafar, Ruh et al. 2002; Rantalainen, Torkkeli et al. 2006), etc., have been early carried out, and thereupon design code for shooting range has been formulated.
Corrosion degree of lead bullet is related to service life of a shooting range (Levonmaki, Hartikainen et al. 2006), bullet structure and physicochemical property of soil (Ma, Hardison Jr et al. 2007).

The samples PU/PTFE and PU/NPs/PTFE (Fig. 2c and 2d) present aggregated structures on their surface, due to agglomerates of bare PTFE particles, causing an increase in the surface roughness of both materials in the submicron range.
This is due to the fact the PTFE coated surfaces are exposed, showing the same morphology and the same surface chemistry in both cases, as revealed also by the SEM inspection and WCA results.
