EU sets purity levels for carbon dioxide fumigant
The European Commission has amended the EU agrochemical approval of the fumigant, carbon dioxide, to set maximum levels for five impurities. The active ingredient gained EU re-registration in 2009 under a faster procedure for low-risk substances (Agrow No 560, p 8). This allowed approval to be granted before the completion of the European Food Safety Authority (EFSA) peer review. The EFSA has now delivered its assessment, resulting in new maximum levels in ppm v/v for the following impurities: phosphane 0.3; benzene 0.02; carbon monoxide 10; methanol 10; and hydrogen cyanide 0.5. The new levels will apply from November 1st.
