Chemical compound containing molybdenum as the central element
The European Union is considering the authorization of a new feed additive for pollinator insects, specifically bee storks, under Article 4(1) of the regulatory framework. The organization behind the application, however, remains undisclosed in the publicly available sources.
The feed additive in question is a solid preparation containing a complex compound of dimolybdate with sodium salt of ethylenediaminetetraacetic acid (EDTA). It boasts a molybdenum content ranging from 27 to 31 % (w/w).
The total molybdenum in the feed additive can be determined using the internationally recognised ring-trial validated EN 15510 method based on inductively coupled plasma-atomic emission spectrometry (ICP-AES). Similarly, the total sodium content can be determined using several methods, including the ring-trial validated EN 15621 method based on ICP-AES and ISO 6869 method based on atomic absorption spectrometry (AAS).
For the determination of total molybdenum in compound feed (sugar syrup and candy bread), the European Reference Laboratory (EURL) recommends the ring-trial validated EN 17053 method based on inductively coupled plasma-mass spectrometry (ICP-MS).
The feed additive is intended to be added into compound feed (sugar syrup or candy bread) for pollinator insects at levels of 2 mg/L sugar syrup or 8 mg/kg candy bread. The recommended dose is 8 mg of the feed additive per hive for both types of compound feed.
To prove the complex formation between molybdate and EDTA in the feed additive, the qualitative method based on Fourier transformed infrared spectroscopy (FTIR) is recommended. The EURL also recommends the use of various methods for the determination of total sodium content and further characterization of the feed additive.
Notably, no further testing or validation of the methods is considered necessary as per Article 10 of Commission Regulation (EC) No 378/2005, indicating the confidence in the established analytical methods.
This new feed additive, if approved, could potentially provide a significant boost to the health and productivity of pollinator insects, contributing to the overall health of our ecosystems. The identity of the organization behind the application remains a mystery, but the scientific rigor and transparency of the methods employed are clear.
