1 “On September 11, 2001, Americans and the world witnessed a new kind of war. We saw the great harm that a stateless network could inflict upon our country, killers armed with box cutters, , and 19 airline tickets. Those attacks raised the prospect of even worse dangers – of other weapons in the hands of other men. The greatest threat before our humanity today is the possibility of secret and sudden attack with chemical or biological or radiological or nuclear weapons.”

President George W. Bush February 11, 2004

12 ❑ Chemicals play important roles in our everyday lives. ❑ Found in a wide range of household and commercial products that can be lifesaving as well as hazardous to our health. ❑ Accidents do happen; threat of terrorist activity may include the use of chemicals as weapons. ❑ Chemical releases and exposure have serious implications for human health and the environment. ❑ Preparing for and responding to chemical terrorism and chemical emergencies are important functions of public health. 13 ❑ Public health personnel, not "first responders“ staff, assess short and long-term impacts on human health, food, water, and sanitation, and order actions to protect the public from chemical contamination. ❑ They work with local hospitals and health care providers to assure essential medical services. ❑ They may also interview victims or provide backup to first responders and medical staff. ❑ State and federal public health agencies become involved if the event is larger than can be handled with local resources. 14 15 ❑ Type of contaminants / media ❑ Magnitude of incident - expect large numbers of affected population ❑ Develop disaster response plans based on what people will likely do rather than expected to do (i.e., anxiety, panic, chaos, fear, hysteria) ❑ Communicate pertinent information. This is paramount to quench fears and mass hysteria ❑ Know available resources and key contacts

(federal, State, private, universities) 16 ❑Why do sample collection? ❑What is the regulatory driver? ❑How will the analytical data ultimately be used? ❑Will the decision by the user be risk based or technology based? ❑What information may still be needed? ❑Appropriate analytical factors to be considered.

17 Environmental sampling for chemical analysis is an attempt to take representative portion of a physical system from its surroundings so that valid scientific decisions can be made concerning the entire ecosystem.

20 Correct Sample + Proper Sample + Prescribed Test Collection Procedure Handling Method & QCs

+ Multiple Reviews (effective QA Program) = Good Defensible Test Results

21 About 30% of total error associated with analytical data is contributed by sampling variability. The chemistry of the contaminants and the specifics of the collection, preservation, and handling processes must be understood so that the concentration can be measured with a high degree of accuracy. Data generated is then legally defensible.

It is important we know HOW to sample, WHEN to sample, WHERE to sample, FREQUENCY of sampling, sampling requirements, etc.

22 ❑Sample collection/distribution 1,000 urine cups? 4,000 vacutainers? Ship to CDC or surge lab (LRN Level 1 or 2)? ❑Sample handling/preparation Aliquot generation Prep “all” samples for network? Sample storage? ❑Data reduction/validation ❑Results reporting

23 ❑In 1999, CDC/NCEH was tasked with analyzing clinical samples from people with suspected exposure to chemicals from: A domestic terrorist event A chemical accident  An unknown chemical exposure

24 ❑Level THREE laboratories Sample collection, storage, and shipment ❑Level TWO laboratories Level One activities plus Analysis of samples for specific agents

❑Level ONE laboratories Level three and Level Two activities plus Serve as CDC’s surge capacity for the analysis of specific agents

25 TERROR

Explosives

26  Primary emphasis on battlefield designated chemical agents – agents  Less emphasis on toxic industrial materials (TIMs) or compounds (TICs)

27 They are highly toxic, poisonous chemical compounds that injure or kill exposed individuals through dermal contact, inhalation or ingestion. They are used in chemical warfare because of the impact of their chemical effects to cause incapacitation and death instead of their physical effects like a blast.

28 CHEMICALS ARE DIVERSE ….

29 Attacks involving thefts/release could impact health and safety, disrupt local/regional economy and impact other critical infrastructure (water systems, chemical plants, etc.). For example, a total failure to protect a (or ammonia) tanker or rail car could discharge contents in 10 minutes and result in plume exceeding 14 miles in length. Goal – To reduce or eliminate the hazard; not to control it.

30 ❑ Terrorist threat is a dynamic phenomenon that continues to evolve in response to social, political, and technological changes.

❑ Terrorists acts will continue to emerge and evolve with new ways to cause human death and infrastructure destruction.

31 ❑The use of chemicals to harm or alter the behavior of an adversary. Risks are more than traditional use of chemical warfare agents ❑Often, it uses existing stores of chemicals – exploiting existing stores of opportunity ❑Huge availability of stored toxic chemicals throughout the US. Close proximity of these industrial operations to large urban centers

32 ❑Chemical insecurity - across the US, thousands of industrial facilities use and store hazardous chemicals in large quantities that pose major risks to residents and their communities. More than 100 of these facilities would each put at least 1M people at risk of injury or death in the event of a chemical release.

33 ❑Think of Bhopal, India, December 1984. Accidental release of methyl isocyanate resulted in massive casualties ❑More than 800,000 US businesses use, produce, or store TICs / TIMs ❑750 plants have enough chemicals to injure or kill at least 100,000 people ❑Terrorist attack on a chemical plant in a densely populated area could result in 2.4 million casualties

34 54% - sufficient information 7% - some information 38% - very little information

30 biotoxins 9 explosives 17 radioisotopes 30 chemical warfare agents Remainder are Toxic Industrial Chemicals (~ 30% registered by EPA as components of pesticide products or mixtures) 35 ❑ Covert Act Hidden or unannounced Difficult to identify and localize ❑ Overt Act Obvious Clear time and location

36  Emergency response by first response teams and MD Public Health laboratories First response team to properly collect, package and ship samples to the lab Public health laboratories to immediately screen, characterize, or analyze chemical agent or send them to another site for testing

37 ❑Chemical attack by religious cult (Aum Shinryko) ❑Emphasizes ease of preparation and use of ❑Vials of chlorosarin and NaF in isopropanol ❑Upon exiting subway train, passenger(s) stepped on paper bag containing vials and crushing them ❑Compounds came in contact, sarin gas formed immediately and was inhaled by surrounding passengers

❑Resulted in 5,000 casualties, 12 deaths 38 ❑Gas released in Bhopal, India ❑Methyl isocyanate used in the production of the pesticides, Sevin (carbaryl) and Temik (aldicarb) ❑Shortly after midnight, 12/3/84, water entered a reactor vessel containing MIC ❑Estimated 40 tons of methyl isocyanate, cyanide, monoxide, and monomethyl amine gases were released into the atmosphere (community)

39 ❑Thousands of deaths immediately after exposure ❑Hundreds of delayed deaths ❑Tens of thousands of casualties – some with permanent lung diseases and others with permanent disabilities ❑More laws passed – prompted SARA Title III

40 41  Chlorine gas as a weapon  Chemical terrorism concerns  Homeland Security Authorities fear chemical terrorism in US  Department of Homeland Security National Planning scenarios  Chlorine thefts  Tallahassee.com article  USA TODAY article

42 The most likely target for terrorists seeking to release large quantities of chlorine are the railcars that travels across the US carrying huge 90-ton tanks of chlorine. U.S. railroads annually carry 1.7 million shipments of hazardous materials, of which 100,000 are toxic chemicals prone to become airborne in an accident. About 80 percent of the latter shipments consist of chlorine. Thirty-seven water utilities in the US still receive chlorine gas by rail, generating 45,000 shipments annually. A March 2007 report by the Center for American Progress cited the Iraqi insurgent attacks to justify its assessment that "railcars of chlorine gas represent a distinct national security vulnerability.“ (World Politics Watch, May 9, 07, Richard Weitz) 43 Although many chemical agents are by nature insidious, clinical (blood & urine) specimens collected from individuals following exposure may not contain any of the actual agents, but may contain metabolites (breakdown products) instead

44  Industrial chemicals (TICs / TIMs) Heavy metals / Trace metals PCBs Pesticides Organic chemicals  Chemical warfare agents (CWA) Blister/Vesicant agents Nerve agents Blood agents

45 ❑Arsenic ❑Tungsten ❑Mercury ❑Antimony ❑Lead ❑Uranium ❑Barium ❑Cadmium ❑Chromium ❑Beryllium

46 ❑Chlorinated pesticides ❑Pyrethroid pesticides ❑Organophosphate pesticides

❑Others (PCBs, Dioxins, Furans, VOCs, PBDEs, etc.)

47 ❑Nerve agents G-series (e.g., sarin, , cyclohexyl-sarin) V-series (e.g., VX, VG, VE) ❑Blister / Vesicant agents (e.g., , mustards) ❑Blood agents (e.g., cyanide, chloride) ❑Choking agents (e.g., chlorine, , ammonia) ❑ (e.g., LSD, fentanyl, thorazine) ❑ (e.g., )

48 Difference between Toxic Industrial Chemicals (TIC) and Chemical Warfare Agents (CWA) may be intent and magnitude

49 The primary goal of proper sample collection and preparation is to ensure samples remain representative and intact from collection to chemical analysis.  Stabilize analyte and matrix  Minimize impact of loss and contamination  Quantify and control loss and contamination

50 ❑Local HAZMAT or first responders identify or suspect an incident ❑Laboratories collect and ship initial samples to CDC ❑CDC laboratories perform PCR and Rapid Toxic Screen on initial samples ❑CDC provides guidance to LRN partners for the analysis of remaining samples

Sample Disseminate Lab Analysis Data Evaluation Collection Information

Samples Data Transfer Technical Conclusions 52 In a CT or chemical emergency …. ❑Avoid the courier system, if possible. ❑Limit the number of persons coming in contact with sample. ❑Conform to proper sample collection, packaging and shipping protocols. ❑Fill out all forms accurately, completely, date and sign as required. ❑Call the appropriate laboratory to alert staff, if possible.

53 ❑CoC is required because samples collected from various sites exposed to chemical agents are regarded as forensic as well as diagnostic ❑The CoC should contain the signature of each person who has custody of the sample at any given time ❑The CoC is not required for each container collected, but for each set of sample containers collected from one site

54 ❑ Encourage registered sanitarians or health care personnel collect the specimen and be involved throughout. ❑ Facility should have a written approved ER Plan. ❑ Vertical and lateral integration and coordination. ❑ Phone numbers of key contact (update often). ❑ Stockpile supplies and store securely. ❑ Practice drills and / or exercises at facility. ❑ Train and re-train personnel, expand. ❑ Periodic meetings to share updated information. 55 ❑Dr. Jack M.
