Safety of a feed additive consisting of diclazuril (Clinacox® 0.5%) for chickens for fattening and chickens reared for laying (Elanco GmbH). [PDF]

EFSA J
Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety of the coccidiostat diclazuril (Clinacox® 0.5%) for chickens for fattening and chickens reared for laying. The FEEDAP Panel has recently adopted an opinion on Clinacox® 0.5% for the renewal of its authorisation.

Model approach for estimating potato pesticide bioconcentration factor [PDF]

Chemosphere, 2008
We presented a model that estimates the bioconcentration factor (BCF) of pesticides in potatoes supposing that the pesticide in the soil solution is absorbed by the potato by passive diffusion, following Fick's second law. The pesticides in the model are nonionic organic substances, traditionally used in potato crops that degrade in the soil according ...

Water temperature affects the biotransformation and accumulation of a psychoactive pharmaceutical and its metabolite in aquatic organisms

Environment International, 2021
Pharmaceutically active compounds (PhACs) have been shown to accumulate in aquatic and riparian food-webs. Yet, our understanding of how temperature, a key environmental factor in nature, affects uptake, biotransformation, and the subsequent accumulation

Immobilized Keratin HPLC Stationary Phase—A Forgotten Model of Transdermal Absorption: To What Molecular and Biological Properties Is It Relevant?

Pharmaceutics, 2023
Chromatographic retention data collected on immobilized keratin (KER) or immobilized artificial membrane (IAM) stationary phases were used to predict skin permeability coefficient (log Kp) and bioconcentration factor (log BCF) of structurally unrelated ...

Bioconcentration Factor (BCF) and Translocation Factor (TF) of Heavy Metals in Mangrove Trees of Blanakan Fish Farm

Makara Journal of Science, 2017
In the mangroves of Blanakan, Indonesia, silvofishery practices may play a role in maintaining the environmental quality of ponds. Mangroves are known as pollutant traps since their root systems absorb and accumulate materials.

QSAR-QSIIR-based prediction of bioconcentration factor using machine learning and preliminary application

Environment International, 2023
Bioconcentration factor (BCF) is one of the important parameters for developing human health ambient water quality criteria (HHAWQC) for chemical pollutants. Traditional experimental method to obtain BCF is time-consuming and costly.

Toxicokinetics and bioconcentration of polycyclic aromatic hydrocarbons in freshwater isopods [PDF]

, 1999
A novel method based on a first-order two-compartment model was used to determine the bioconcentration and toxicokinetic rate constants of six different polycyclic aromatic hydrocarbons (PAHs) in the freshwater isopod Asellus aquaticus, a common species ...

Transfer of metals from crude oil impacted soils to some native wetland species, the Niger-delta, Nigeria: Implications for phytoremediation potentials [PDF]

Journal of Agricultural Sciences (Belgrade), 2016
In this study, wetland species growing naturally in the surrounding of two crude oil facilities were sampled and screened for their phytoremediation potentials for zinc, lead, nickel, chromium and cadmium in soil. Concentrations of metals in the
