Systems and methods for removing hydrocarbons and other pollutants from roadway surfaces are provided. The systems can include a pollution trap attached to a vehicle, where the pollution trap comprises an absorbent pad, filter, or membrane. The pollution trap is affixed to the vehicle, for example, in the wheel well, on a mud flap, on the underside of a vehicle or another suitable place where the pollution trap can be exposed to a roadway pollutant. The methods described herein can include liberating roadway pollutants from a roadway and using a pollution trap to collect the liberated roadway pollutants.

What is claimed is: 1. An apparatus on a vehicle for collecting pollutant particles liberated from a roadway, comprising: an element comprising a material configured to retain roadway pollutant particles, that are 10 μm or less, which are liberated from said roadway by a tire of said vehicle,
What is claimed is: 1. An apparatus on a vehicle for collecting pollutant particles liberated from a roadway, comprising: an element comprising a material configured to retain roadway pollutant particles, that are 10 μm or less, which are liberated from said roadway by a tire of said vehicle, wherein said element is affixed to said vehicle at a location that receives a spray of said liberated roadway pollutant particles. 2. The apparatus of claim 1, wherein said element is attached to a portion of a wheel well of the vehicle. 3. The apparatus of claim 1, wherein said material is magnetic. 4. The apparatus of claim 1, wherein said material is configured to collect pollutants that are less than about 5 microns. 5. The apparatus of claim 1, wherein said material is configured to collect pollutants that are less than about 2.5 microns. 6. The apparatus of claim 1, wherein said material is configured to collect hydrocarbons and heavy metals. 7. The apparatus of claim 1, wherein said material is configured to collect pollutants emitted from deteriorated brake pads. 8. The apparatus of claim 1, wherein said material comprises a filter. 9. The apparatus of claim 1, wherein said material comprises a pad. 10. The apparatus of claim 1, said element comprises one or more electrically charged plates. 11. The apparatus of claim 1, wherein said material comprises a binding agent that binds a pollutant particle in said spray of pollutant particles to said material when said pollutant particles contact said element. 12. The apparatus of claim 2, wherein said element is attached to a surface of said wheel well substantially between a surface of said wheel well and said rotating tire of said vehicle. 13. The apparatus of claim 1, wherein said element is attached to a mud flap of said vehicle. 14. The apparatus of claim 1, wherein said element is positioned behind a portion of the surface of a wheel well. 15. The apparatus of claim 1, wherein said element is attached to the underside of said vehicle. 16. The apparatus of claim 1, wherein said element is attached to a splash guard of said vehicle. 17. The apparatus of claim 1, further comprising a frame configured to hold said element on said vehicle. 18. The apparatus of claim 1, wherein said material is oleophilic. 19. The apparatus of claim 1, wherein said material is porous. 20. The apparatus of claim 1, wherein said material is hydrophobic. 21. A method for collecting pollutant particles liberated from a roadway surface, the method comprising: positioning an element to receive a spray of roadway pollutant particles that are liberated from the roadway by a tire of a vehicle, wherein said element comprises a material configured to collect said pollutant particles that are 10 μm or less; contacting the roadway with a tire of the vehicle; rotating the tire to liberate pollutant particles from the roadway; receiving said pollutant particles on said material; and collecting at least a portion of said pollutant particles on said material. 22. The method of claim 21, wherein said element is attached to a portion of a wheel well of said vehicle. 23. The method of claim 21, wherein said material is magnetic. 24. The apparatus of claim 21, wherein said material is configured to collect pollutants that are less than about 5 microns. 25. The apparatus of claim 21, wherein said material is configured to collect pollutants that are less than about 2.5 microns. 26. The apparatus of claim 21, wherein said material is configured to collect pollutants comprising heavy metals. 27. The apparatus of claim 21, wherein said material is configured to collect pollutants comprising hydrocarbons. 28. The apparatus of claim 21, wherein said material comprises a filter. 29. The apparatus of claim 21, wherein said material comprises a pad. 30. The apparatus of claim 21, wherein said material comprises binding agents that bind a pollutant particle in said spray of pollutant particles to said material when said pollutant particles contact said material. 31. The apparatus of claim 21, wherein said element is attached to a surface of said wheel well substantially between a surface of said wheel well and said rotating tire of said vehicle. 32. The apparatus of claim 21, wherein said element is attached to a mud flap of said vehicle. 33. The apparatus of claim 21, wherein said element is positioned behind a portion of the surface of a wheel well. 34. The apparatus of claim 21, wherein said element is attached to the underside of said vehicle. 35. The apparatus of claim 21, wherein said element is attached to a splash guard of said vehicle. 36. A system for collecting pollutant particles liberated from a roadway, comprising: a vehicle comprising at least one tire; and an element comprising a material configured to retain roadway pollutant particles, that are 10 μm or less, which are liberated from said roadway by said tire of said vehicle wherein said element is affixed to said vehicle at a location that receives a spray of said liberated roadway pollutant particles. 37. The system of claim 36, wherein said vehicle comprises a wheel well and said element is affixed to a portion of said wheel well. 38. The system of claim 37, wherein said vehicle comprises an inlet on said wheel well, said inlet configured to allow the spray of said pollutant particles to flow through said inlet, arid wherein said element is affixed to a location to receive said pollutant particles that flow through said inlet.
