The wg discussed and agreed on uncertainty factors to be used for reference values derivation. They are used commonly in plastics, textiles and electrical/electronic equipment At efsa we peer review the risk assessment of active substances used in plant protection products (i.e

Pesticides) before they can be placed on the eu market or before the renewal of a currently approved substance
We are also responsible for the assessment of maximum residue levels (mrls) which refer to the highest level of a pesticide residue that is legally tolerated in or on food or feed.
The scientific committee confirms that the threshold of toxicological concern (ttc) is a pragmatic screening and prioritisation tool for use in food safety assessment This guidance provides clear step‐by‐step instructions for use of the ttc approach The inclusion and exclusion criteria are defined and the use of the ttc decision tree is explained The approach can be used when the.
The european commission mandated efsa to assess the toxicity of bromide, the existing maximum residue levels (mrls), and possible transfer from feed into food of animal origin The critical effects of bromide in experimental animals are on the thyroid and central nervous system Changes in thyroid hormone homeostasis could result in neurodevelopmental toxicity, among other adverse effects. The provision of historical control data (hcd) is a data requirement for pesticide active substances established by european legislation
Hcd are data from studies conducted under the same or similar conditions as the toxicity study under assessment (index study)
The collation, use and interpretation of hcd is currently not harmonised The panel on plant protection products and their residues. The systemic toxicity was assessed by means of a repeated dose 90‐day oral toxicity study in rats The panel identified a no observed adverse effect level of 2000 mg tos/kg bw per day, the highest dose tested, which when compared with the estimated dietary exposure, resulted in a margin of exposure of at least 1286.
Review research on moh toxicity since 2012 and update the scientific opinion on the hazard characterisation (potential for harm) of moh Estimate the exposure levels of moh considering recent occurrence data And consequently, update the risk characterisation (the likelihood that harm will happen) of moh, based on these recent data.
