Reconstructed human epidermis‐based testing strategy of skin sensitization potential and potency classification using epidermal sensitization assay and in silico data

Journal of Applied Toxicology, Volume 44, Issue 3, Page 415-427, March 2024.
Abstract The hazards and potency of skin sensitizers are traditionally determined using animal tests such as the local lymph node assay (LLNA); however, significant progress has been made in the development of non‐animal test methods addressing the first three mechanistic key events of adverse outcome pathway in skin sensitization.

Specific effects on the thyroid relevant for performing a dietary cumulative risk assessment of pesticide residues: 2024 update

EFSA Journal, Volume 22, Issue 3, March 2024.
Abstract EFSA updated its previous work on the establishment of specific effects that are considered relevant for grouping pesticide residues targeting the thyroid and for performing the retrospective assessment of dietary cumulative risk (CRA). The two specific effects already selected in 2019 leading to the two cumulative assessment groups (CAGs ...

Influence of tank mixtures of pre-emergence herbicides on growing leeks (Allium porrum L.) [PDF]

Acta Agriculturae Serbica, 2015
The effect of mixtures of pre-emergence herbicides on weed infestation and yield of leek was evaluated. Three tank mixtures were applied: s-metolachlor (Dual Gold 960 EC at a dose of 80 ml/da) + oxyfluorfen (Goal 2 E at a dose of 100 ml/da); s ...

Prioritisation of pesticides and target organ systems for dietary cumulative risk assessment based on the 2019–2021 monitoring cycle

EFSA Journal, Volume 22, Issue 2, February 2024.
Abstract Aiming at accelerating the implementation of cumulative risk assessment to pesticide residues, this report describes a two‐step prioritisation analysis, on individual pesticides and on target organ systems, that allows to identify (i) low‐priority substances expected to have a marginal contribution to cumulative risk, and (ii) high priority ...

Effect of adjuvants on the dissipation, efficacy and selectivity of three different pre-emergent sunflower herbicides

Plant, Soil and Environment, 2017
The aim of this work was to compare the efficacy, selectivity to sunflower and dissipation of three pre-emergent herbicides. Flurochloridone, linuron and oxyfluorfen were applied individually and each herbicide was also applied in a tank mix with two ...
