“…For the least potent plastic, soaking 1 mg of polystyrene plastic in a milliliter of water generates a solution that kills 42% of barnacle larvae in 24 h. For the most potent plastic, the leachate can be diluted to the equivalent of 7.0 µg of plastic leached in seawater and kill half the larvae. As neither the polymer or its monomer leach, toxicity can be ascribed to the 50 + to several hundred compounds that can be detected by high resolution mass spectrometry (Li et al, 2016a), such as unpolymerized labile organic carbon molecules, petrochemical constituents, heavy metals, organometals with steroidal activity, organic environmental steroids, toxicants and flavors, that can elicit a potent biological response (Al-Malack, 2001;Hahladakis et al, 2018;Groh et al, 2019;Diana et al, 2020). Unlike most other products in which compound classes can indicate relative toxicities to various organisms, the plastic recycle category provides little information about biological activity of molecules impacting microorganisms.…”

“…Due to these processes, plastics are dynamic, with both their surface chemistries and leachate compositions changing over time and generating novel environments. That plastics are chemically active and dynamic underscores the need to understand their interactions and toxicity in the marine environment (Diana et al, 2020).…”

“…Microspheres are small enough to be consumed by larvae and some can enter tissues of larvae (Yu and Chan, 2020b) and fish. In contrast, pre-production pellets are 2-4 mm in all dimensions, are delivered dry (not in preservatives), are too large to be consumed by larvae and are ingested and egested by larger animals without entering tissues (Allen et al, 2017;Diana et al, 2020).…”

Plastics of various chemistries pollute global water bodies. Toxic chemicals leach with detrimental and often unpredictable impacts on the surrounding ecosystems. We found that seawater leachates of plastic pre-production pellets from 7 recycle categories are acutely toxic to stage II barnacle nauplii; lethal concentration 50 (LC50s) were observed in 24-h leachates from dilutions ranging from 0.007 to 2.1 mg/mL of seawater. Based on previous observations that macro-organismal settlement on fouling management coatings of various toxicities can be used to predict the toxicity of the coating, we hypothesized that interaction of plastic pre-production pellets with emerging microbiomes would exhibit patterns indicative of the chemistry at the pellet surface. We used amplicon sequencing of bacterial 16S ribosomal RNA genes to characterize the microbiomes that developed from 8 through 70 days on pellets exposed to the same flowing ambient seawater. Diversity and composition of the microbiomes colonizing plastic pellets changed over time and varied with plastic type. Microbial taxa belong to taxonomic groups known to consume hydrocarbons, to be prevalent following marine oil spills, or to live on fouling management surfaces. Microbiomes were still distinct between plastic types at Day 70, suggesting that differences in the physicochemical characteristics of the underlying plastics continue to exert variable selection of surface microbial communities. A random forest-based sample classifier correctly predicted 93% of plastic types using microbiome compositions. Surface microbiomes have promise for use in forensically identifying plastic types and potential toxicities.

“…Plastic debris, especially microplastics, have been found worldwide in all marine compartments and is increasing in volume (Isobe et al 2019). These plastics release chemicals that are assumed to affect the chemosensory behavior of organisms; for example, the sea anemone Exaiptasia pallida has been found to ingest plastic pellets (Diana et al 2020).…”

Chemical cues for intraspecific chemical communication and interspecific interactions in aquatic environments: applications for fisheries and aquaculture

2021

Aquatic organisms detect chemical cues to sense the local environment, for example, to find a mate, locate food, and identify danger. Knowledge of chemical cues can be used in aquaculture, in practical applications such as controlling mating behavior to increase fertility, enhance feeding, and decrease stress; in fisheries, by catching selected species with low-cost artificial attractants; and to address maritime issues, by decreasing biofouling. Aquatic organisms also detect chemical cues related to global environmental changes, ocean acidification, and increases in ocean plastics, all of which can affect their chemosensory behaviors. Here we discuss the nature of chemical cues and chemosensory biology and ecology of aquatic organisms, and potential applications with an emphasis on sex pheromones in commercially important and well-studied animals, namely, decapod crustaceans and fish.

“…This can lead to effects on detritivores [17] and filter feeder species [18][19][20], while also affecting marine foodstuffs and humans [21][22][23][24]. Recent research highlighted that plastics can interact at different levels with feeding responses in tested species (i.e., hard corals, [25]; oysters, [26]; sea anemones, [27]. Furthermore, other important biological functions could be impacted such as spore settlement and aggregation in Ulva tepida [28] and settlement and growth in bryozoans [29].…”

This study evaluates the impacts of 16 different leachates of plastic-made packaging on marine species of different trophic levels (bacteria, algae, echinoderms). Standard ecotoxicological endpoints (inhibition of bioluminescence, inhibition of growth, embryo-toxicity) and alterations of ecologically significant parameters (i.e., echinoderms’ body-size) were measured following exposure under different pH water conditions: marine standard (pH 8.1) and two increasingly acidic conditions (pH 7.8 and 7.5) in order to evaluate possible variations induced by ocean acidification. The results obtained in this study evidence that the tested doses are not able to significantly affect bacteria (Vibrio fischeri) and algae (Phaeodactylum tricornutum). On the contrary, Paracentrotus lividus larvae were significantly affected by several packaging types (13 out of 16) with meaningless differences between pH conditions.
