Quantifying the trophic transfer of sub-micron plastics in an assembled food chain

Quantifying dielectrophoretic collections of sub-micron particles on microelectrodes

This paper presents a technique for measuring and quantifying the dielectrophoretic collection of sub-micron particles on planar microelectrode arrays. Fluorescence microscopy and video recording is used to measure the number of particles collecting on an electrode as a function of time for various experimental parameters, such as applied electrode voltage and frequency. Video images are proces...

Bioaccumulation, biotransformation and trophic transfer of arsenic in the aquatic food chain.

The occurrence, distribution, speciation, and biotransformation of arsenic in aquatic environment (marine and freshwater) have been studied extensively by several research groups during last couple of decades. However, most of those studies have been conducted in marine waters, and the results are available in a number of reviews. Speciation, bioaccumulation, and biotransformation of arsenic in...

Bioaccumulation, Biotransformation and Trophic Transfer of Arsenic in the Aquatic Food Chain: A Review

Trophic transfer of seven trace metals in a four-step marine food chain

There is increasing recognition of the importance of dietary pathways in determining metal body burdens in marine organisms. With a simple kinetic model that requires information about the ingestion rate of an animal and the assimilation efficiency (AE) and efflux rate constant (ke) of a metal following dietary exposure, it is possible to quantitatively predict the trophic transfer and biomagni...

Food-chain transfer of zinc

This study examines the food-chain transfer of Zn from two plant species, Urtica 31 dioica (stinging nettle) and Acer pseudoplatanus (sycamore maple), into their corresponding 32 aphid species, Microlophium carnosum and Drepanosiphum platanoidis. The plants were 33 grown in a hydroponic system using solutions with increasing concentrations of Zn from 0.017 34 to 42 mg Zn/l, although U. dioica o...
