The environmental fate of sodium azide (NaN3) is of considerable interest given the recent surge in production to satisfy demand for automobile air bag inflators, where it serves as the principal active ingredient. Since the mid-1990s, demand for sodium azide has exceeded 5 million kg per year and most passenger vehicles sold in the United States now contain approximately 300 g (≈0.7 lb) of sodium azide. This has greatly increased the potential for accidental environmental releases and for… 

Development of a novel method to measure sodium azide using the vitamin B12 precursor cobinamide

Although the cobinamide based method is less sensitive than ion chromatography or gas chromatography methods, the assay described in this paper has a potential higher throughput, is easier to process, and is sensitive enough to detect potentially toxic concentrations in biological samples.

Perchlorate and ion chemistry of road runoff

Environmental context. Recognising that road flares and air bags may contribute perchlorate to road runoff, we analysed perchlorate in runoff from two accident-prone suburban highways during a period

Mol 2 Net 14 N NMR Spectroscopy Study of Binding Interaction between Sodium Azide and Hydrated Fullerene

The presence of human pharmaceutical compounds in surface waters is an emerging issue in environmental science. Low levels of many active pharmaceutical ingredients are detected in the aquatic

This review examines physicochemical properties, environmental fate, and metabolism of the various potential methyl bromide replacement products.

Sodium azide poisoning: a narrative review

Recent increases in azide poisoning reports may stem from greater commercial use and availability and treatment of systemic poisoning may require aggressive hemodynamic support due to profound hypotension.

Development of a novel method for sodium azide removal from aqueous solution using amberlite IRA-900: batch and column adsorption studies

In this work, the adsorption characteristics of amberlite IRA-900 chloride resin (amberlite) for azide ions sorption were investigated. The elimination of azide ions from aqueous solution in the

Sensitive electrochemical detection of sodium azide based on the electrocatalytic activity of the pasting liquid of a carbon paste electrode

This paper has developed an effective method for the electrochemical detection of sodium azide in which silicone oil was employed as the pasting liquid of the carbon paste electrode and exhibited comparable sensitivity to the boron-doped diamond thin-film electrode and highly oriented pyrolytic graphite electrode.
