“…As such, the concentration and bioavailability of Cu in natural environments is very important when considering ecosystem health (Flemming and Trevors, 1989). The bioavailability of Cu depends on speciation (ionic, complexed, or nano, oxidation states) and environmental factors including pH, redox potential, water, soil and sediment type, water hardness, and organic content (Garner and Keller, 2014;Flemming and Trevors, 1989;Cornelis et al, 2014). In comparison to terrestrial organisms, Cu tends to be quite toxic to aquatic biota, whose sensitivity to Cu and Cu NPs depends on factors such as surface-area-to-volume ratio, respiratory rates, and, for fish, flow rate over gill surfaces, among others (Flemming and Trevors, 1989).…”

A B S T R A C TGiven increasing use of copper-based nanomaterials, particularly in applications with direct release, it is imperative to understand their human and ecological risks. A comprehensive and systematic approach was used to determine toxicity and fate of several Cu nanoparticles (Cu NPs). When used as pesticides in agriculture, Cu NPs effectively control pests. However, even at low (5-20 mg Cu/plant) doses, there are metabolic effects due to the accumulation of Cu and generation of reactive oxygen species (ROS). Embedded in antifouling paints, Cu NPs are released as dissolved Cu + 2 and in nano-and micron-scale particles. Once released, Cu NPs can rapidly (hours to weeks) oxidize, dissolve, and form CuS and other insoluble Cu compounds, depending on water chemistry (e.g. salinity, alkalinity, organic matter content, presence of sulfide and other complexing ions). More than 95% of Cu released into the environment will enter soil and aquatic sediments, where it may accumulate to potentially toxic levels (> 50-500 μg/L). Toxicity of Cu compounds was generally ranked by high throughput assays as: Cu + 2 > nano Cu(0) > nano Cu(OH) 2 > nano CuO > micron-scale Cu compounds. In addition to ROS generation, Cu NPs can damage DNA plasmids and affect embryo hatching enzymes. Toxic effects are observed at much lower concentrations for aquatic organisms, particularly freshwater daphnids and marine amphipods, than for terrestrial organisms. This knowledge will serve to predict environmental risks, assess impacts, and develop approaches to mitigate harm while promoting beneficial uses of Cu NPs.

“…Because soils and sediments appear to be major sinks for nanomaterials, these compartments must be considered in addition to pelagic aquatic compartments [50,51]. This is already reflected in the ecotoxicity tests seen for the ERA for human pharmaceuticals (Table 2).…”

Many new developments and innovations in health care are based on nanotechnology. The field of nanopharmaceuticals is diverse and not as new as one might think; indeed, nanopharmaceuticals have been marketed for many years, and the future is likely to bring more nanosized compounds to the market. Therefore, it is time to examine whether the environmental risk assessment for human pharmaceuticals is prepared to assess the exposure, fate, and effects of nanopharmaceuticals in an adequate way. Challenges include the different definitions for nanomaterials and nanopharmaceuticals, different regulatory frameworks, the diversity of nanopharmaceuticals, the scope of current regulatory guidelines, and the applicability of test protocols. Based on the current environmental risk assessment for human medicinal products in the European Union, necessary adaptations for the assessment procedures and underlying study protocols are discussed and emerging solutions identified.
