The minimal public version is available here. The full report is only being made available to State Parties and will likely make its way into the public domain at a later date. The OPCW public report contains a surprising amount of information if you know what to look for.

The TAV team notes that the toxic chemical was of high purity. The latter is concluded from the almost complete absence of impurities. This is an explosive finding. It completely undermines the statements of the May government. Observation 1 — Purity Industrial bulk production of any product will introduce impurities into that product.

The product may be The fact the production process leaves minute trace evidence in the form of impurities offers a forensic method that may be used to identify the source of the material. If you can identify the production location then you can identify the State Party associated with the production of that material.

Observation 2 — Lab Grade The absence of impurities is strong evidence of the suspect toxin not having come from a production run of toxic chemical. It is evidence of the toxin having been created in a laboratory environment.

Science is based on shared universal knowledge. A key aspect of all scientific practice is ensuring the validity of any research process. This includes the necessity to remove all possible contaminants that may compromise the research. Materials created in a laboratory will typically exhibit a greater degree of purity than the same product derived from bulk industrial production.

This implies the availability of well trained and knowledgeable technicians, and laboratory support workers, in addition to the research scientists. It also implies a significant budget for materials, beakers, wash stations, test instruments, glove boxes, ventilation hoods, the safe disposal of any vapours, or any other waste material, a means to ensure a constant stream of filtered air, airlocks, a positive or negative pressure containment, a set of written laboratory guidelines and an enforced set of practices intended to maintain the necessary work environment.

All of the foregoing costs money. A lot of money.

Associated Data

The OPCW report provides confirmation that the toxin was not cooked up in a bedsit by a single individual bent on mayhem. It required a degree of resources only to be found in a sophisticated laboratory setting.daily exposure" (PDE) is defined in the present guideline as a pharmaceutically acceptable intake of residual solvents to avoid confusion of differing values for ADI's of the same substance.

This report is the 33rd Annual Report of the Toxic Hazards Research Unit (THRU) and presents scientific activities of the ManTech Geo-Centers Joint Venture contract on behalf of the toxicology.

Jun 06,  · After exposure, distilled water was added to both hydrated and desiccated samples, and the samples were transferred into culture dishes (35 mm in diameter) with distilled water and Chlorococcum sp..

The tardigrade culture was conducted as the same manner as described above. The recommended standard is based on the conclusion that valid evidence of skin absorption, blood and liver effects, and tumor induction in experimental animals is relevant to human exposure." (Ref.
