“…In addition, copper-based nanoparticles are increasingly being used in industrial applications (Gao et al, 2013). We are unable to identify metal sources, but boating activity, in addition to nanoparticles (Thit et al, 2015) would be areas to investigate. Considering Johnson et al (2017) Table S1: Mesocosm physiochemical water quality data Biol.…”

“…Influence of shape on bioaccumulation was also reported for TiO 2 (of unknown size), with higher levels of bioaccumulation and trophic transfers for TiO 2 NPs in paddy microcosms than for TiO 2 NTs (Yeo and Nam 2013). On the other hand, shape has been shown not to have any significant effect on the bioaccumulation of 6, 71-, and 139nm CuO nanospheres, 7-, 73-, and 126-nm CuO nanorods, and 7-, 56-, and 133-nm CuO nanospindles in the estuarine sediment-dwelling polychaete N. diversicolor (Thit et al 2015).…”

The experimental determination of bioaccumulation is challenging, and a number of approaches have been developed for its prediction. It is important to assess the applicability of these predictive approaches to nanomaterials (NMs), which have been shown to bioaccumulate. The octanol/water partition coefficient (K ) may not be applicable to some NMs that are not found in either the octanol or water phases but rather are found at the interface. Thus the K values obtained for certain NMs are shown not to correlate well with the experimentally determined bioaccumulation. Implementation of quantitative structure-activity relationships (QSARs) for NMs is also challenging because the bioaccumulation of NMs depends on nano-specific properties such as shape, size, and surface area. Thus there is a need to develop new QSAR models based on these new nanodescriptors; current efforts appear to focus on digital processing of NM images as well as the conversion of surface chemistry parameters into adsorption indices. Water solubility can be used as a screening tool for the exclusion of NMs with short half-lives. Adaptation of fugacity/aquivalence models, which include physicochemical properties, may give some insights into the bioaccumulation potential of NMs, especially with the addition of a biota component. The use of kinetic models, including physiologically based pharmacokinetic models, appears to be the most suitable approach for predicting bioaccumulation of NMs. Furthermore, because bioaccumulation of NMs depends on a number of biotic and abiotic factors, it is important to take these factors into account when one is modeling bioaccumulation and interpreting bioaccumulation results.

“…The shape of the particle did have an effect with a preferential accumulation of rod shaped nanoparticles in the body. In a similar study Thit et al (2015) exposed the polychaete Nereis diversicolor to different sizes of copper oxide nanoparticle in sediment. The nanoparticle did not affect the burrowing ability of the worm but the copper aqueous control did decrease its ability.…”

This review covers selected 2015 articles on the biological effects of pollutants and human physical disturbances on marine and estuarine plants, animals, ecosystems and habitats. The review, based largely on journal articles, covers field and laboratory measurement activities (bioaccumulation of contaminants, field assessment surveys, toxicity testing and biomarkers) as well as pollution issues of current interest including endocrine disrupters, emerging contaminants, wastewater discharges, dredging and disposal, etc. Special emphasis is placed on effects of oil spills and marine debris due largely to the 2010 Deepwater Horizon oil blowout in the Gulf of Mexico. Several topical areas reviewed in the past (ballast water and ocean acidification) were dropped this year. The focus of this review is on effects, not pollutant fate and transport. There is considerable overlap across subject areas (e.g.some bioaccumulation papers may be cited in other topical categories). Please use keyword searching of the text to locate related but distributed papers. Use this review only as a guide and please consult the original papers before citing them.
