Removal of Pb and Zn from Soil using cowpea (Vigna unguiculata) and maize (Zea mays) Plants

Journal of Applied Sciences and Environmental Management, 2018
This study investigated the potential of cowpea (Vigna unguiculata) and maize (Zea mays) plants to remove Pb and Zn from soil. The crops were exposed to three concentrations (100, 150 and 200 mgkg-1) of each metal salts during the study. When the plants

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 ...

Phytoremediation of Soils Contaminated with Cadmium by Agave americana

Journal of Natural Fibers, 2022
Agave americana was evaluated for its phytoremediation potential of the soils contaminated with Cd. This plant was selected because of its drought tolerance and high biomass.

QSPR models for bioconcentration factor (BCF): are they able to predict data of industrial interest?

SAR and QSAR in environmental research (Print), 2019
The bioconcentration factor (BCF), a key parameter required by the REACH regulation, estimates the tendency for a xenobiotic to concentrate inside living organisms. In silico methods can be valid alternatives to costly data measurements.

BIOACCUMULATION OF LIPID – SOLUBLE POLLUTANTS IN AQUATIC SYSTEMS [PDF]

Croatian Journal of Fisheries, 1999
One of the major problems of water pollution is the capability of pollutants to concentrate in aquatic organisms. Bioaccumulation and bioconcentration of such chemicals in fish render it unsuitable for human consumption.
