V. Tsiridis,Maria Petala,Petros Samaras,S. Hadjispyrou,George P. Sakellaropoulos,A. Kungolos +5 more
TLDR
The effect of humic acids (HAs) on the toxicity of copper, zinc, and lead was investigated using the photobacterium Vibrio fischeri (Microtox test) as a test organism and the effects of HAs on metal toxicity were evaluated as functions of time and concentration in pure compound solutions.About:

A Copper-Activated Two-Component System Interacts with Zinc and Imipenem Resistance in Pseudomonas aeruginosa
TL;DR: CopR is a new negative regulator of OprD porin and that it links Zn, Cu, and imipenem resistances by interacting with the CzcRS TCS.

Comparison of toxicity and release rates of Cu and Zn from anti-fouling paints leached in natural and artificial brackish seawater.
TL;DR: The results suggest that the amounts of Zn and Cu leached from anti-fouling paints may attain toxic concentrations in areas with high boat density and that Zn as well as active ingredients should be considered in the regulatory process.

Evaluation of chemical and ecotoxicological characteristics of biodegradable organic residues for application to agricultural land
Paula Alvarenga,Patrícia Palma,A.P. Gonçalves,R.M. Fernandes,A.C. Cunha-Queda,Elizabeth Duarte,Giovanni Vallini +6 more
TL;DR: Considering the results, the use of a battery of toxicity test in conjunction with chemical analysis should be suggested, in order to correctly assess possible environmental risks deriving from disposal or land application of biodegradable organic residues.

Hazard/Risk Assessment BIOTIC LIGAND MODEL OF THE ACUTE TOXICITY OF METALS. 1. TECHNICAL BASIS
Dominic M. Di Toro,H Erbert E. Allen,Harold L. Bergman,Joseph S. Meyer,Paul R. Paquin,Robert C. Santore +5 more
TL;DR: The biotic ligand model of acute metal toxicity to aquatic organisms is based on the idea that mortality occurs when the metal-biotic ligand complex reaches a critical concentration, a generalization of the free ion activity model that relates toxicity to the concentration of the divalent metal cation.

Humic Ion-Binding Model VI: An Improved Description of the Interactions of Protons and Metal Ions with Humic Substances
TL;DR: In this article, a discrete site/electrostatic model of the interactions of protons and metals with fulvic and humic acids is applied to 19 sets of published data for proton binding, and 110 sets for metal binding.

Monitoring approaches to assess bioaccessibility and bioavailability of metals: matrix issues.
TL;DR: An analysis of the physicochemical and biological determinants underlying bioavailability and bioaccessibility concludes that, lack of a universal expression of bioavailable and bioaccessible metal fractions precludes the presentation of a detailed monitoring strategy that is broadly applicable.
