Abstract
A method for conducting environmental sampling includes determining to environmentally sample a particular paper transit ticket for a specific residue. Using an automated ticket device, at least one chemical reagent is applied to the particular paper transit ticket. The chemical reagent is selected based on the specific residue. The particular paper transit ticket is collected after the particular paper transit ticket was used as a fare media within a transit system. The at least one chemical reagent is analyzed to determine whether any of the specific residue is present.
Claims20
A method for conducting environmental sampling, the method comprising:
- determining to environmentally sample a particular paper transit ticket for a specific residue;
- applying, using an automated ticket device, at least one chemical reagent to the particular paper transit ticket, the chemical reagent being selected based on the specific residue;
- collecting the particular paper transit ticket after the particular paper transit ticket was used as a fare media within a transit system;
- and
- analyzing the at least one chemical reagent to determine whether any of the specific residue is present.
An automated ticket device for use in environmental sampling, comprising:
- a ticket receiving mechanism configured to receive a plurality of paper transit tickets;
- a ticket scanner configured to read data on each of the plurality of paper transit tickets;
- and
- a sorting mechanism configured to sort the plurality of paper transit tickets according to the data read from each of the plurality of paper transit tickets, wherein:
- the sorting is based on which of the plurality of paper transit tickets are to be environmentally sampled;
- and
- a subset of the sorted plurality of paper transit tickets are to be environmentally tested for a particular contaminant.
A method for conducting environmental sampling, the method comprising:

- scanning, using the automated ticket device, data from each of the plurality of paper transit tickets;
- and
- sorting the plurality of paper transit tickets according to the data read from each of the plurality of paper transit tickets, wherein:
- the sorting is based on which of the plurality of paper transit tickets are to be environmentally sampled;
- and
- a subset of the sorted plurality of paper transit tickets are to be environmentally tested for a particular contaminant.
