“…Therefore, in the previously developed methods for the determination of lewisite [2][3][4] in samples of water, soil, construction materials, and air based on its conversion into acetylene, lewisite was determined together with the products of its oxidation and hydrolysis, which also react with a 30% aqueous solution of sodium hydroxide yielding acetylene.…”

“…Although lewisite and lewisite oxide belong to the compounds of the first hazard class, their MPCs in the air of work areas are substantially different, 2.0 × 10 -4 and 1.0 × 10 -2 mg/m 3 , respectively [2,5,6]. The above consideration indicates that the residual concentrations of lewisite and lewisite oxide in soil and construction materials must be known for their use in the national economy after detoxication.…”

Gas-Chromatographic Separate Determination of Trace β-Chlorovinylarsonous Dichloroanhydride (Lewisite) and Anhydride (Lewisite Oxide) in Soil and Construction Materials

A method was proposed for the separate gas-chromatographic determination of β -chlorovinylarsonous dichloroanhydride (lewisite) and anhydride (lewisite oxide) in samples of soil and construction materials. Because of the absence of regulations for the maximum permissible concentration (MPC) of lewisite and lewisite oxide in construction materials (concrete, bricks, facing tile, etc.), the MPC level of lewisite in soil (0.1 mg/kg) was taken as the maximum permissible concentration in the development of the method for their determination in the above samples. The method is based on the solid-liquid extraction converting lewisite and lewisite oxide into components that can be separated at the stage of blowing-out the extractant in an inert gas flow and their subsequent conversion into acetylene with a 30% aqueous solution of sodium hydroxide and the chromatography of the vapor phase with flame-ionization detection. The error in the determination is no larger than ± 20 rel %. The time of analysis is within 1.5 h.

This article discusses the preparation of environmental samples to be analyzed for chemicals related to the Chemical Weapons Convention (CWC), where analysis takes place off‐site by gas chromatography (GC) or liquid chromatography (LC) as an introduction technique to spectrometers, or by capillary electrophoresis (CE). The specific sample preparation methods required for analysis by spectroscopic techniques such as nuclear magnetic resonance (NMR) spectroscopy are dealt with in separate articles. Preparations of air, aqueous liquid (water), soil, active charcoal, wipe, and concrete samples, and samples of paint, rubber, and other polymeric materials for off‐site analysis are presented in Section 2 and are as described in the corresponding recommended operating procedures (ROPs). In addition, preparations of organic liquid samples are presented, as described in the in‐house operating procedures of the Finnish Institute for CWC analysis. Section 3 examines the question of quality control (QC) in sample preparation and Section 4 discusses the important matter of safety in handling samples that may contain CWC‐related chemicals. Section 5 reports on the use of the methods in international comparison and proficiency tests.

The trans-2-chlorovinyldichloroarsine (Lewisite) was produced and handled during WWI and WWII as chemical warfare agents. It was very difficult to explore its chemical characterization by experiments ways. The quantum chemical calculations proved to be a precise and harmless method for the toxicological system. In this paper, the gas phase reaction mechanisms of OH radical with trans-2-chlorovinyldichloroarsine (lewisite) were studied by second-order Møller-Plesset perturbation theory (MP2) method. The geometries of reactants, products, complexes, and transition states were optimized at the MP2/6-311++G(d,p) level. To gain more accurate mechanistic knowledge, the single-point energies were calculated using G3 and CCSD(T) method. This reaction exhibited three mechanisms, namely, direct hydrogen abstraction, direct chlorine abstraction, and addition/elimination. Multichannel Rice-Ramsperger-Kassel-Marcus theory and transition-state theory have been carried out for overall and individual rate constants over a wide range of temperatures and pressures. The computational results indicated that addition/elimination reaction is more favorable than direct hydrogen abstraction and direct chlorine abstraction. The major products for the total reaction are AsCl2 and CHClCH2O generated via C(2)-addition/elimination.
