Bioaccumulation of Polychlorinated Dibenzo-p-Dioxins (PCDDs) and Dibenzofurans (PCDFs) in Hediste diversicolor (Polychaeta: Nereididae)

Frontiers in Ecology and Evolution, 2020
The effectiveness and reliability of the polychaete Hediste diversicolor (O.F. Müller, 1776) to bioaccumulate polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) was assessed in an in-situ passive biomonitoring study.

Luminescence characteristics of dibenzofuran and several polychlorinated dibenzofurans and dibenzo-p-dioxins

Talanta, 1988
The room-temperature fluorescence (RTP), low-temperature phosphorescence (LTP) and room-temperature phosphorescence (RTP) characteristics of dibenzofuran and several polychlorinated dibenzofurans and dibenzo-p-dioxins are presented and are shown to be suitable for the determination of these compounds. The limits of detection are as low as 0.02, 0.2 and

Re‐evaluation of sucralose (E 955) as a food additive and evaluation of a new application on extension of use of sucralose (E 955) in fine bakery wares

EFSA Journal, Volume 24, Issue 2, February 2026.
Abstract The present opinion deals with the re‐evaluation of sucralose (E 955) as food additive and with the safety of a proposed extension of use in food category (FC) 7.2 ‘Fine bakery wares’. Based on the available data, no safety concerns arose for genotoxicity of sucralose (E 955) and its impurities and degradation products.
