WebWhether crop intercropping can affect the uptake of phthalic acid esters (PAEs) by plant roots from soils is unclear. In this study, we compare the PAE uptake by plant roots between the wheat/maize intercropping and the wheat and maize monocropping in a field work. We show that the PAE bioconcentration factors of wheat and maize roots are remarkably … WebBioconcentration factor。 生物濃縮倍率。特定時間暴露したときの水生生物中の化学物質の濃度を同じ時間または同じ期間の周辺の水中の濃度で割った値。生物濃縮係数とも言う。

WebBioconcentration factor (BCF) is the heavy metal concentration present in the plant biomass divided by heavy metal in FA (Raj et al., 2024 ). It is an important parameter in phytoremediation determining information on the metal uptake, its mobilization into the plant tissues, and storage in the shoot parts ( Newman & Unger, 2003 ).
