“…Like the literature on Cu nanoparticles, the broader literature on benthic community effects from nanoparticles reports widely varying effect concentrations depending on the type of nanoparticle and the exposure test system [64][65][66][67][68][69]. Standardized test protocols for nanomaterials are in their infancy [70], and standardized test systems to evaluate benthic communities vary widely with type of exposure, dosing parameters, and exposure period [28,[71][72][73][74][75][76]. Standardization of test procedures is critical for better understanding the fate and effects of nanoparticles on benthic communities.…”

The widespread use of copper nanomaterials (CuNMs) as antibacterial and antifouling agents in consumer products increases the risk for metal contamination and adverse effects in aquatic environments. Information gaps exist on the potential toxicity of CuNMs in marine environments. We exposed field-collected marine meio- and macrobenthic communities to sediments spiked with micronized copper azole (MCA) using a novel method that brings intact benthic cores into the laboratory and exposes the organisms via surface application of sediments. Treatments included field and laboratory controls, 3 spiked sediments: low-MCA (51.9 mg/kg sediment), high-MCA (519 mg/kg sediment), and CuSO (519 mg/kg sediment). In addition, single-species acute testing was performed with both MCA and CuSO Our results indicate that meio- and macrofaunal assemblages exposed to High-MCA and CuSO treatments differed significantly from both the laboratory control and the low-MCA treatments. Differences in macrofauna were driven by decreases in 3 Podocopa ostracod species, the bivalve Gemma gemma, and the polychaetes Exogone verugera and Prionospio heterobranchia relative to the laboratory control. Differences in the meiofaunal community are largely driven by nematodes. The benthic community test results were more sensitive than the single-species test results. Findings of this investigation indicate that CuNMs represent a source of risk to marine benthic communities comparable to that of dissolved Cu. Environ Toxicol Chem 2018;37:362-375.

“…Aquatic environment including lakes, rivers, seas [2] and groundwater [3,4], is the environmental compartment more affected by the daily input of those organic chemicals. Xenobiotics, called also as Organic Micropollutants (OMPs) can alter aquatic organisms at nanogram to milligram per liter levels [5,6] producing endocrine disruption and neurotoxicity [7]. Some OMPS are bioaccumulative [8] and could reach the higher levels of trophic chain, like humans [9,10].…”

In the present work, a sensitive, simple, and fast method with little sample handling has been developed for the determination of 34 semi-volatile organic xenobiotics from rain, sea and ground waters. The method is based on Headspace-Solid Phase Microextraction (HS-SPME) and Gas Chromatography coupled to Mass Spectrometry (GC-MS/MS). Sixteen Polycyclic Aromatic Hydrocarbons (PAHs), eight Phthalate Esters (PEs), six Polychlorinated Biphenyls (PCBs) and two Alkylphenols (APs) were quantitative analyzed in a single run. The best parameters for extraction were determined, including fiber type, sample volume, salinity and extraction time and temperature. In the optimized procedure, 15 ml of water sample was extracted using a 100 μm PDMS fiber in a 20 ml vial and adding 3 g of NaCl (final NaCl concentration of 20%) during 40 min at 80°C (with 10 min of previous equilibration time). A desorption time of 15 min was shown to eliminate carry-over. The method showed good linearity between 0.01 and 10 μgL -1 (r 2 from 0.987-0.999). Good precision (63-123%) and accuracy were achieved (1.1-21%). The Methodological Detection Limits (MDL) ranged from 0.00001-0.01364 µg L -1 . The method was successfully applied to real samples collected at Ensenada (Mexico). The proposed method represents an effectively and valuable tool for application in environmental water monitoring programs.
