“…Nauplii originating from synchronised cultures (24h) were obtained from ovigerous females [35]. As reported in the previous paragraph, MP accumulation was also evaluated in copepods after 48 h by exposing nauplii to 1-4 µm Cospheric polyethylene green fluorescently labelled particles.…”

Toxicity of polyethylene microplastics (PE-MP) of size ranges similar to their natural food to zooplanktonic organisms representative of the main taxa present in marine plankton, including rotifers, copepods, bivalves, echinoderms and fish, was evaluated. Early life stages (ELS) were prioritized as testing models in order to maximize sensitivity. Treatments included particles spiked with benzophenone-3 (BP-3), a hydrophobic organic chemical used in cosmetics with direct input in coastal areas. Despite documented ingestion of both virgin and BP-3 spiked microplastics no acute toxicity was found at loads orders of magnitude above environmentally relevant concentrations on any of the invertebrate models. In fish tests some effects, including premature or reduced hatching, were observed after 12 d exposure at 10 mg L of BP-3 spiked PE-MP. The results obtained do not support environmentally relevant risk of microplastics on marine zooplankton. Similar approaches testing more hydrophobic chemicals with higher acute toxicity are needed before these conclusions could be extended to other organic pollutants common in marine ecosystems. Therefore, the replacement of these polymers in consumer products must be carefully considered.

“…In all acute toxicity tests, the survival of negative controls was > 98%. The reference toxicant LC50 was equal to 0.17 mg/L (0.14-0.22 mg/L) being comparable to (Faraponova et al 2016;Prato et al 2015Prato et al , 2012 (0.18-0.14 mg/L). The median lethal concentration for T. fulvus exposed to MPs and leachates was calculable only for BN.…”

“…The aim of our research was to investigate the potential acute (mortality) and sub-chronic (mortality, larval development and moult release number, and adult percentage after 5-9 days) toxicity of derelict plastic tubular nets in the microplastics form using the marine copepod Tigriopus fulvus as a reference biological model being a primary consumer living at the sediment-water interface (Faraponova et al 2005(Faraponova et al , 2016Mariani et al 2006;Prato et al 2011Prato et al , 2015Prato et al , 2012Prato et al , 2013Prato et al , 2020Tornambè et al 2012). Derelict plastic tubular nets were analysed considering five main colours (BN, YN, GN, PN, and WN) to investigate any potential relation between plastic colour and potential observed toxicity.…”

Microplastic debris from direct and indirect human activities is considered a major threat to the marine biodiversity mainly due to its abundance, durability, persistence, and ability to accumulate contaminants from the environment. Derelict tubular plastic nets of various colours (blue (BN), yellow (YN), green (GN), pink (PN), and white (WN) net), used to distinguish mussel farming owners, were collected by scuba-dive from the Mar Piccolo of Taranto (Ionian Sea). All nets were made of polypropylene. Investigations looked for potential acute (mortality) and sub-chronic (mortality, larval development and moult release number, and adult percentage after 5–9 days) effects on Tigriopus fulvus nauplii considering both whole plastics (microplastic (MP), 50 mg/L) and leachates (12.5–100%). Acute test determined a median lethal concentration (LC50) only for BN for both MPs (107 mg/L) and leachates (50.1%). The prolonged exposure (5 days) to microplastics did not affect the T. fulvus survival. After 9 days, YN and BN decreased of approximately 100% larval development. Graphical abstract

“…18 T. fulvus is also known to be an useful test species in ecotoxicology, whose reliability was tested with different matrices and pollutants. [19][20][21][22][23][24][25][26][27] This species inhabits splashpools or rockpools, and therefore it is exposed to a wide variety of environmental conditions that promoted refined adaptation and resistance characteristics. Such variability is ascribed to cycles of drying out or inundation of rockpools, depending on rainfall, waves exposition and sunlight.…”

Effects of environmental factors on Tigriopus fulvus, Fischer 1860, a Mediterranean harpacticoid copepod

2018

Tigriopus fulvus (Fischer, 1860) is a benthic harpacticoid copepod of the Mediterranean supralittoral zone. The transitional characteristics of this environment forced this species to develop high resistance to changes of environmental parameters. Nevertheless, Tigriopus fulvus life-cycle is influenced from the splashpools physical-chemical parameters. In this paper, we present the results of a supralittoral monitoring performed in 2014, confirming the influence of some of these environmental parameters on population buildups. Because of recent worldwide climate change effects, a threat might have been posed on this particularly exposed organism, whose population density decreased of a sixfold value in the last 30 years. During the three pools (A, B, C) monitoring, the maximum copepod density recorded was 1456 Ind/l (September 2014, Pool C), alongside first records of extinction event for Tigriopus fulvus.
