Abstract
Provided is a method of surveillance for hazardous materials, e.g., chemical, biological and radiological agents. The method comprises assaying a sample derived from materials collected from a sample domain for the presence of a chemical, biological, or radiological agent. The sample domain comprises at least one collection point from which the materials are collected in a pre-existing operation unrelated to surveillance.

4. A method of surveillance for the presence of a chemical, biological, or radiological agent, which method comprises:
-
assaying a sample derived from street debris materials collected from a sample domain for the presence of a chemical, biological, or radiological agent, comprising the steps of; (a) treating the sample to reduce the concentration of bacteria that are preferentially bioencapsulated by Tetrahymena pyriformis relative to the bioencapsulation of Bacillus anthracis;
(b) introducing Tetrahymena pyriformis to the sample, and (c) assaying for Bacillus anthracis;
wherein the sample domain is a route undertaken by a street sweeper machine through a city street and comprises at least one collection point from which the materials are collected from a city street in a pre-existing operation, otherwise unrelated to surveillance.

-
(a) treating a sample derived from street debris materials collected from a sample domain to reduce the concentration of bacteria that are preferentially bioencapsulated by Tetrahymena pyriformis relative to the bioencapsulation of Bacillus thuringiensis; and (b) assaying the sample for the presence of a chemical, biological, or radiological agent, wherein the sample domain is a route undertaken by a street sweeper machine through a city street and comprises at least one collection point from which the materials are collected from a city street in a pre-existing operation, otherwise unrelated to surveillance, wherein the sample is assayed for Bacillus thuringiensis.

44. A method of detecting the presence of a chemical, biological, or radiological agent which comprises:
-
(a) obtaining at least one sample from a collection of street debris that has been exposed to the environment and is collected from a street sweeper machine that follows a pre-defined, traceable route unrelated to surveillance and continuously collects the street debris from an open environment along the pre-defined route; (b) assaying the sample for the presence of a Bacillus spore within the sample comprising introducing Tetrahymena pyriformis to the sample, and assaying the sample for the presence of a Bacillus spore; (c) determining a result based on the assay; and (d) reporting the result. - View Dependent Claims (45, 46)
