Plastics enter in terrestrial natural system primarily by agricultural purposes, while acid rain is the result of anthropogenic activities. The synergistic effects microplastics and on plant growth are not known. In this study, different sizes polyethylene terephthalate (PET) tested Lepidium sativum, two separate experimental sets. first one we treated plants only with PET, second used PET together. both experimentations analyzed: i) biometrical parameters (shoot height, leaf number,...

Microplastics (MPs) pose biological and chemical hazards in aquatic terrestrial food webs across the globe. Research on microplastic contamination has long focused marine ecosystems, whereas toxicological impact freshwater organisms is still little explored. In this study, lethal sublethal response of macroinvertebrate Hydropsyche pellucidula exposed to polypropylene MPs after different pre-conditioning treatments was assessed. Field samples were collected a riverine system (Vipacco river;...

The study reports the enzymatic synthesis of bio-based oligoesters and chemo-enzymatic processes for obtaining epoxidized bioplasticizers biolubricants starting from cardoon seed oil. All molecules had MW below 1000 g mol-1 were analyzed in terms marine biodegradation. data shed light on effects chemical structure, bond lability, thermal behavior, water solubility Moreover, analysis biodegradation building blocks that constituted different products allowed us to distinguish between...

The effective management of marine ecosystems in the face growing anthropogenic pressures requires integration data from different ecological components. Holistic approaches to evaluate status are still scarce, likely due challenge integrating complex information a variety indicators. In this study, we provided an application quantitative Weight-Of-Evidence (WOE) model based on Sediqualsoft® software, combining environmental and biological assess risk soft-bottom habitats within Natura sites...

Coralligenous bioconstructions are priority habitats crucial for the protection of Mediterranean marine biodiversity. Among these bioconstructions, mesophotic biogenic reefs northern Adriatic particular concern due to their ecological relevance and high levels human pressure in region. Thus, effective monitoring strategies vital conservation management fragile environments. In this study, we investigated multivariate spatial temporal patterns sessile macrobenthos on within two areas a Natura...

This study evaluates the impacts of 16 different leachates plastic-made packaging on marine species trophic levels (bacteria, algae, echinoderms). Standard ecotoxicological endpoints (inhibition bioluminescence, inhibition growth, embryo-toxicity) and alterations ecologically significant parameters (i.e., echinoderms’ body-size) were measured following exposure under pH water conditions: standard (pH 8.1) two increasingly acidic conditions 7.8 7.5) in order to evaluate possible variations...

The most worrisome fraction within plastic pollution is that of microplastics (MP). A category MP almost completely ignored glitter. objective this study to test the toxicity nine types glitter leachate (3 soak times: 3, 90 and 180 days) on model organisms in freshwater (Allivibrio fischeri, Raphidocelis subcapitata, Daphnia magna) saltwater Phaeodactylum tricornutum, Paracentrotus lividus). An integrated approach was applied obtain percentage ecotoxicological risk. results show (i)...

Each year, a staggering 700,000 tons of synthetic dyes are manufactured globally, leading to the release dye-laden wastewater into aquatic systems. These resist biodegradation, endangering human and environmental health. Since traditional treatments basically unable remove dyes, exploring potential alternative solutions, such as bioremediation, is crucial reduce dye contamination in ecosystems. Ficopomatus enigmaticus (Fauvel 1923), listed one 100 worst invasive species Europe, considered an...

Cigarette butts (CBs) are among the dominant constituents of marine and beach litter. Few studies have been conducted, environmental effects CBs on species still poorly understood. This study aims to evaluate ecotoxicological organisms both classic electronic CBs. Three representative different trophic levels in ecosystems (Aliivibrio fischeri, bacteria; Phaeodactylum tricornutum, algae, primary producers; Paracentrotus lividus, echinoderms, consumers) were tested. The natural ageing due...

There is one type of primary microplastic, glitter, which has not received the same attention as microbeads. The general thought associates use glitter with extraordinary and rare events, in reality, its presence everyday life much more ubiquitous than might think. main objective this preliminary study was to create a mini product survey aim analyzing distribution composition local market city Trieste (Italy), thus creating starting point for larger future studies. analysis real context...

On 30 January 2020, the World Health Organization declared a public health emergency of international concern due to rapid spread among humans, on global scale, SARS-CoV-2, virus responsible for COVID-19. Although authorities have recommended use common detergents known be effective against coronaviruses, one practices implemented control expansion has been massive disinfectants indoor and outdoor surfaces, modality that raised in scientific community because its impact aquatic environment....

This study reports on the presence of microplastics in gastrointestinal tracts and livers demersal fish (the mullet, Mullus spp.) from a Marine Protected Area (Porto Cesareo) along Ionian Sea coast (Apulia, Southern Italy). The results showed microplastic ingestion more than 60% specimens analyzed with an average three items per levels red mullets being almost twice as high congeneric striped mullets. dominant polymers identified by Attenuated Total ReflectanceFourier Transform Infrared...

An intra-laboratory calibration to quantify microplastic in fine-grained marine sediments was performed with two objectives: (a) determine the recovery rate of self-produced microplastics characterized by a size ranging from 220 µm 5 mm and differing color (pink, orange, gray, yellow, silver), shape (fragments, filaments, spheres, films), chemical composition (polystyrene, polyethylene, polyvinyl chloride, acrylonitrile-butadiene-styrene, polypropylene, poly(methyl methacrylate))...

In this study, a systematic review of the scientific literature was carried out to summarize emerging evidence on microplastic pollution in natural caves. After screening 655 papers topic from combined search Web Knowledge and Scopus databases, we found only 14 studies reporting quantitative data microplastics total 27 Most assessments focused water sediment, with very limited investigations concerning cave biota. Overall, most common types particles caves were small (<1 mm) fibers...
