the present pot experiment was undertaken to investigate the phytoremediation potential of corn and oat in soil. treatments consisted of four cadmium (cd) levels (0, 5, 10 and 20 mg l 1) and three irrigation intervals (1, 3 and 7 days), arranged in the form of a complete randomized design with three replications. corn and oat were harvested after 75 and 90 days, respectively. transpiration rate...

Michigan Chemical Corporation, St. Louis, Michigan manufactured PBB from 1970 until November 20, 1974. Studies in 1974 showed significant quantities of PBB in effluent discharged from the facility and in water, fish, ducks, and sediments from the Pine River. Fish uptake rates and bioconcentration factors were estimated. Followup surveys over the three year period since the termination of PBB pr...

The toxic effects of Lindane (γ-BHC) on Microcystis aeruginosa were studied under lab culture conditions. Total protein levels, as well malondialdehyde (MDA) levels and superoxide dismutase (SOD) enzyme activity, in algal cells, determined after exposure to different concentrations Lindane. bioaccumulation Lindane, the influence pH dissolved organic matter (DOM) effects, was also evaluated cell...

Wetland macrophytes have advantages when used in the remediation of cadmium (Cd)-contaminated paddy fields because they can adapt to overly wet soil environments; however, only a few studies tested efficiency Cd phytoremediation. In this study, we investigated effect pH (pHs 5, 6, and 7) on accumulation translocation by Polygonum hydropiper (L.) low moderately Cd-contaminated (0.56 0.92 mg/kg, ...

Agricultural practices such as wastewater irrigation and manure application may contaminate soils with antibiotics and, consequently, lead to human health risk. The co-application of three waste-derived materials, sewage sludge (SL), Chinese medicinal herbal residues (CMHR) biochar (BC), a soil amendment was proposed recently for minimizing the antibiotic amount in crop tissues. fate six antibi...

The samples of 4 mushroom species from the genus Leccinum ((Leccinum pseudoscabrum (Kallenb.) Šutara, scabrum (Bull.) Gray, duriusculum (Schulzer ex Kalchbr.) Singer, and albostipitatum den Bakker & Noordel) were picked 6 forested areas Slovakia in 2020 (Čačín – Jelšovec, Hliník Hronom, Kurima Taraš, Mníšek nad Popradom, Snina Štefekovo, Žákylské pleso). Total mercury content soil parts was...

Abstract The toxicokinetic (TK) model‐derived kinetic bioconcentration factor (BCF k ) provides a quantitatively comparable index to estimate the bioaccumulation potential of nanoparticles (NPs) that barely reach thermodynamic equilibrium in aquatic organisms, but experimental data are limited for various NPs. In present study, machine learning model was applied offer reliable silico prediction...

We measured the transfer of radiocesium in a marine food chain from phytoplankton to bivalves and finally to a predatory gastropod (Babylonia formosae habei). The assimilation efficiency (AE) of radiocesium in both green mussels (Perna viridis) and the gastropods feeding on different diets was measured by a pulse-chase feeding radiotracer technique. The AEs of 137Cs in the green mussels ranged ...

Five widely used metrics of bioaccumulation in fish are defined and discussed, namely the octanol-water partition coefficient (KOW ), bioconcentration factor (BCF), bioaccumulation factor (BAF), biomagnification factor (BMF), and trophic magnification factor (TMF). Algebraic relationships between these metrics are developed and discussed using conventional expressions for chemical uptake from w...
