Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 10, October 2025.Abstract Globally, nutrient enriched water bodies are major contributors to the aquatic greenhouse gases (GHG) efflux to atmosphere. However, few efforts have focused on assessing the contribution from coastal transitional ecosystems in Africa. To improve our knowledge of these systems, we investigated emissions in Lake Nokoué, a coastal lagoon in ...

Re‐evaluation of saccharin and its sodium, potassium and calcium salts (E 954) as food additives
EFSA Journal, Volume 22, Issue 11, November 2024.Abstract This opinion deals with the re‐evaluation of saccharin and its sodium, potassium and calcium salts (E 954) as food additives. Saccharin is the chemically manufactured compound 1,2‐benzisothiazol‐3(2H)‐one‐1,1‐dioxide. Along with its sodium (Na), potassium (K) and calcium (Ca) salts, they are authorised as sweeteners (E 954).
