Native Plant Capacity for Gentle Remediation in Heavily Polluted Mines

Applied Sciences, 2021
The use of plant species to stabilize and accumulate trace elements in contaminated soils is considered of great usefulness given the difficulty of decontaminating large areas subjected to mining for long periods.

Parameter uncertainty in modeling bioaccumulation factors of fish [PDF]

Environmental Toxicology and Chemistry, 2011
Abstract We quantified the uncertainty due to biota-related parameters in estimated bioaccumulation factors (BAFs) of persistent organic pollutants for fish through Monte Carlo simulations. For this purpose, the bioaccumulation model OMEGA (Optimal Modeling for EcotoxicoloGical Applications) was parameterized based on data from the ...

Bioaccumulation of polybrominated diphenyl ethers by Tubifex tubifex

Acta Chimica Slovenica, 2016
Selective uptake of PBDEs by oligochaete allows the assessment of the bioaccumulation of individual congeners in commercial mixtures. 21 congeners from three BDE commercial mixtures (TBDE-71, TBDE-79 and TBDE-83R) and as individual congeners (BDE-77, BDE-

Yielding and Bioaccumulation of Zinc by Cocksfoot under Conditions of Different Doses of This Metal and Organic Fertilization

Agronomy, 2022
Zinc is essential for the growth and development of plants, but in excessive amounts in the soil it can be toxic for them. Its mobility depends in part on the organic matter content of the soil.

Influences on Mercury Bioaccumulation Factors for the Savannah River [PDF]

Archives of Environmental Contamination and Toxicology, 2004
Mercury TMDLs (Total Maximum Daily Loads) are a regulatory instrument designed to reduce the amount of mercury entering a water body and ultimately to control the bioaccumulation of mercury in fish. TMDLs are based on a BAF (bioaccumulation factor), which is the ratio of methyl mercury in fish to dissolved methyl mercury in water.

Metal bioaccumulation and translocation studies of Spinacea oleraceae and Celosia argentea cultivated on contaminated soil

Ruhuna Journal of Science, 2019
The quest for tolerant plants with excellent phytoremediation potential is a stark reality. Additionally, the use of dumpsite soil for growing vegetables and ornamental plants is relatively a common practice by farmers in urban cities across Nigeria ...

Determination of lithium bioretention by maize under hydroponic conditions

Archives of Environmental Protection, 2017
Irrigation of cultivated plants can be a source of toxic lithium to plants. The data on the effect of lithium uptake on plants are scant, that is why a research was undertaken with the aim to determine maize ability to bioaccumulate lithium. The research

Soil-to-Wheat Transfer of Heavy Metals Depending on the Distance from the Industrial Zone

Agronomy, 2023
The accumulation of heavy metals in the environment is one of the most significant environmental problems due to the potential risk to human and animal health. The aim of this study was to analyze the influence of the distance from the industrial zone on
