TLDR
It is indicated that ionoregulatory disruption in freshwater mussels chronically exposed to copper is the main mechanism of toxicity and that redox parameters do not appear to be useful as indicators of sub-lethal copper toxicity in these animals.About:

Metal-PAH mixtures in the aquatic environment: a review of co-toxic mechanisms leading to more-than-additive outcomes.
TL;DR: Several key mechanistic interactions likely to promote more-than-additive toxicity in metal-PAH mixtures are outlined, including the deleterious effects of PAHs on membrane integrity and permeability to metals, the potential for metal- PAH complexation, and the mutual inhibition of detoxification suggests the possibility of positive feedback among these mechanisms.

Acute toxicity of 50 metals to Daphnia magna
TL;DR: The acute toxicity results of 40 elements obtained in this study were not correlated with electronegativity, and the acuteoxicity results of metals including the rare metals were also not correlation with first ionization energy, atomic weight, atomic number, covalent radius, atomic radius or ionic radius.

TL;DR: Overall, observed sublethal and lethal effects occurred at concentrations which exceed expected environmental concentrations through aqueous exposure, suggesting a low risk to freshwater mussels from these particular PPCPs.

Effects of copper exposure on the energy metabolism in juveniles of the marine clam Mesodesma mactroides.
TL;DR: In this paper, metabolic changes induced by waterborne Cu exposure were evaluated in the osmoconforming clam Mesodesma mactroides, a bivalve species widely distributed along the South American sandy beaches.

A rapid and sensitive method for the quantitation of microgram quantities of protein utilizing the principle of protein-dye binding
TL;DR: This assay is very reproducible and rapid with the dye binding process virtually complete in approximately 2 min with good color stability for 1 hr with little or no interference from cations such as sodium or potassium nor from carbohydrates such as sucrose.

New spectrophotometric equations for determining chlorophylls a, b, c1 and c2 in higher plants, algae and natural phytoplankton
S.W. Jeffrey,G.F. Humphrey +1 more
TL;DR: New equations are presented for spectrophotometric determination of chlorophylls, based on revised extinction coefficients of chloropylls a, b, c1 and c2, which may be used for determining chlorophyLLs a and b in higher plants and green algae.
