“…Spawning events that occurred in late April-early May (30 April-2 May) each year are responsible for the sharp decline in a mussel's fresh tissue mass, shown in Fig. 4 (Handa et al, 2011;Zaldivar, 2008), which is in agreement with the literature (Sprung, 1983;Cardoso et al, 2007;Saraiva et al, 2012). The predicted weight loss due to spawning was around 7 % at the first year of simulation, while the second, third, and fourth year the percentage of weight loss increased gradually to 8.3 %, 12.6 %, and 14.4 % respectively.…”

“…The simulated abrupt losses of the mussel's tissue mass correspond to spawning events, and the model's prediction was compared with the available literature data regarding the spawning period in each study area. Theodorou et al (2011) demonstrated that the spawning events occur during winter for M. galloprovincialis in the mussel farms of Greece, while in the North Sea the spawning period for M. edulis is extended from the end of April until the end of June (Sprung, 1983;Cardoso et al, 2007).…”

Abstract. Microplastics (MPs) are a contaminant of growing concern due to their widespread distribution and interactions with marine species, such as filter feeders. To investigate the MPs accumulation in wild and cultured mussels, a dynamic energy budget (DEB) model was developed and validated with the available field data of Mytilus edulis (M. edulis, wild) from the North Sea and Mytilus galloprovincialis (M. galloprovincialis, cultured) from the northern Ionian Sea. Towards a generic DEB model, the site-specific model parameter, half-saturation coefficient (Xk), was applied as a power function of food density for the cultured mussel, while for the wild mussel it was calibrated to a constant value. The DEB-accumulation model simulated the uptake and excretion rate of MPs, taking into account environmental characteristics (temperature and chlorophyll a). An accumulation of MPs equal to 0.53 particles per individual (fresh tissue mass 1.9 g) and 0.91 particles per individual (fresh tissue mass 3.3 g) was simulated for the wild and cultured mussel after 4 and 1 years respectively, in agreement with the field data. The inverse experiments investigating the depuration time of the wild and cultured mussel in a clean-from-MPs environment showed a 90 % removal of MPs load after 2.5 and 12 d respectively. Furthermore, sensitivity tests on model parameters and forcing functions highlighted that besides MPs concentration, the accumulation is highly dependent on temperature and chlorophyll a of the surrounding environment. For this reason, an empirical equation was found, directly relating the environmental concentration of MPs, with the seawater temperature, chlorophyll a, and the mussel's soft tissue MPs load.

“…Examination of MP egestion over a 48 hr depuration period showed that MPs were retained in Palaemonetes pugio for an average of 43 hrs, ranging from approximately 28 to 76 hrs depending on the MP polymer type [64]. Egestion of MPs by the mussel Mytilus galloprovincialis was 80% within the first 24 hrs, and 100% within 8 days [65].…”

Bioaccumulation and biomagnification of microplastics in marine organisms: A review and meta-analysis of current data

Microplastic (MP) contamination has been well documented across a range of habitats and for a large number of organisms in the marine environment. Consequently, bioaccumulation, and in particular biomagnification of MPs and associated chemical additives, are often inferred to occur in marine food webs. Presented here are the results of a systematic literature review to examine whether current, published findings support the premise that MPs and associated chemical additives bioaccumulate and biomagnify across a general marine food web. First, field and laboratory-derived contamination data on marine species were standardised by sample size from a total of 116 publications. Second, following assignment of each species to one of five main trophic levels, the average uptake of MPs and of associated chemical additives was estimated across all species within each level. These uptake data within and across the five trophic levels were then critically examined for any evidence of bioaccumulation and biomagnification. Findings corroborate previous studies that MP bioaccumulation occurs within each trophic level, while current evidence around bioaccumulation of associated chemical additives is much more ambiguous. In contrast, MP biomagnification across a general marine food web is not supported by current field observations, while results from the few laboratory studies supporting trophic transfer are hampered by using unrealistic exposure conditions. Further, a lack of both field and laboratory data precludes an examination of potential trophic transfer and biomagnification of chemical additives associated with MPs. Combined, these findings indicate that, although bioaccumulation of MPs occurs within trophic levels, no clear sign of MP biomagnification in situ was observed at the higher trophic levels. Recommendations for future studies to focus on investigating ingestion, retention and depuration rates for MPs and chemical additives under environmentally realistic conditions, and on examining the potential of multi-level trophic transfer for MPs and chemical additives have been made.

“…The selected microplastics were fluorescent polystyrene microspheres purchased from Degradex Hopkinton (MA 01748). These particular beads were selected because of their colour (fluorescent orange with Excitation/Emission 530/582 nm) and because their density was similar to seawater (UNESCO,1981, Capolupo et al, 2018.…”

Microplastics debris (<5 mm) are increasingly abundant in the marine environment, therefore, potentially becoming a growing threat for different marine organisms. Through aquatic animals, these can enter in the human food chain, and can be perceived as a risk for consumers' health. Different studies report the presence of particles in marketable shellfish including the world wide commercially grown Pacific oyster Magallana gigas (Thunberg, 1793). The aim of this study is to examine the potential risk of microplastics entering in the human food chain through this shellfish species, investigating the dynamics of the uptake, egestion (faeces) and rejection (pseudofaeces) of microplastics in Pacific oysters under controlled conditions. M. gigas collected from a farm in the San Teodoro lagoon (Italy), were exposed to 60 fluorescent orange polystyrene particles L-1 of known sizes (100, 250 and 500 µm). The uptake of each particle size was 19.4 ± 1.1%, 19.4 ± 2 % and 12.9 ± 2 % respectively. After exposure M. gigas were left to depurate for 72 hrs, during which 84.6 ± 2 % of the particles taken up were released whilst 15.4 ± 2 % were retained inside the shell cavity. No microplastic particles were found in the animals' soft tissues. The results of this study, suggest that depuration is an effective method to reduce presence of large microplastic particles, in the size range 100 to 500 µm, in M. gigas. Importantly, the data suggests that the burden that could theoretically be up taken by consumers from these shellfish is negligible when compared to other routes. Capsule Microplastic of tested sizes were not retained in the tissues but can be retained in the shell cavity; Depuration is an effective method to reduce microplastics in farmed Pacific oysters
