“…As mentioned above, the precision of the Cu and Zn isotopic measurements was not sensitive to the imperfect concentration match. There are many samples with extremely low Cu and Zn content in nature (27), so it is important to understand the limits of low concentrations in which suitable precision can also be achieved. The concentrations in the samples and standards (Alfa Cu and Alfa Zn were used here, respectively) were changed to the same concentration and acid molarity between the samples and standards.…”

“…Ag uptake rates and concentration in the haemolymph of the marine amphipod Parhyale hawaiensis were described by Vannuci-Silva et al (2018;2019). Authors indicated that animals exposed via food containing AgCl would require more than 100 days to uptake similar amounts of silver absorbed by organisms exposed via water for only 96 hours (Vannuci-Silva et al, 2019).…”

Behavioural responses to contaminants are an important endpoint in ecotoxicology because they link effects at biochemical or cellular levels to impacts on individual fitness. Due to the increasing use of silver in nanomaterials, studies of its effects on the behaviour of aquatic organisms are important to assess the risks of silver nanoparticles (AgNP) released into the environment. The aim of this work was to evaluate the behavioural effects of silver on the marine amphipod Echinogammarus marinus after exposure to AgNO3 via water and AgCl or AgNP via food. Swimming activity of the amphipods was tracked during 6 min alternating dark and light conditions. Animals swam slower and responded less to light at higher concentrations of silver in the water. No differences were found in the behaviour of animals exposed via feeding up to 28 days, hence, longer exposure times may be required for the observation of effects. This is the first work to appraise behaviour effects of silver ions and AgNP on marine amphipods.Although the protocol has been successfully developed for this purpose, specimens appeared to habituate to test conditions during the experiments. Therefore, the need for further understanding of baseline behaviours in these model organisms is discussed.

“…The saline water sample was acidified with HNO 3 2% for Ag preservation. After 1:10 dilution, the sample was directly introduced into the ICP‐MS using a High Matrix Introduction System because it supports a high content of dissolved solids (up to 5%; Vannuci‐Silva et al ). The limit of detection (LOD) and the limit of quantification (LOQ) for the hemolymph were 0.13 and 0.44 µg L −1 , respectively.…”

On release into surface waters, engineered silver nanoparticles (AgNPs) tend to settle to sediments and, consequently, epibenthic fauna will be exposed to them through diet. We established Ag uptake and accumulation profiles over time in the hemolymph of a marine amphipod fed with a formulated feed containing AgNPs or AgCl. Silver bioavailability was higher in organisms exposed to AgNPs, indicating that the nanoparticles pose a higher risk of toxicity compared to similar concentrations of AgCl.
