Photo actu Spéciation

PHYTOCONTROL is pleased to announce you that in addition to your metal analyzes, the R & D department has recently developed a new analysis of speciation and quantification of arsenic by LC-ICP / MS that will be offered from 1 October 2014 on all foods including infant feeding.

Speciation is a technique used to identify the various forms (species, oxidation) of a metal present in a sample. Arsenic is of particular concern because of the toxicity of some chemical forms which have carcinogenic properties.

The main toxic forms are: arsenic pentoxide and arsenate (AsV), arsenic trioxide or Arsenite (AsIII), dimethylarsinic acid (DMA), the monomethylarsonic acid (MMA), arsenobetaine (AsB) and arsenocholine (AsC).

The toxicity of arsenic depends on its chemical nature, inorganic arsenic (AsIII and AsV) is much more toxic than organic arsenic.

The main dietary sources of inorganic arsenic are cereal grains and cereal products, foods with special dietary uses (such as algae), coffee, rice and rice products, as well as fish and vegetables.

To date, the EU regulation does not set maximum levels for total arsenic and inorganic arsenic but discussions are underway within the Codex Alimentarius Commission to determine the need to develop specific regulations on rice.

The 8th session of the Codex, which took place from 31 March to 4 April 2014 are currently not allowed to set thresholds in Inorganic Arsenic in all types of rice, failing agreement between the Commission member states.

However, all Member States of the committee ruled in favor of a threshold at 0.2 mg / kg for polished rice that should be provided to the commission. However, for crude or husked rice, the committee was unable to reach an agreement. In this context, it has been requested to rice-producing countries to provide additional data and further review should take place during the ninth session of the codex to be held in March 2015.
