1. Chemosensory communication between flowers and pollinators is a fundamental component of terrestrial biodiversity, given the importance of olfaction to foraging animals. In this respect, exploring chemically‐mediated interspecific interactions in natural assemblies may provide novel insights into the eco‐functional significance of volatile organ...
Article
Mediterranean lotic waters such as rivers, streams and springs are poorly monitored for non-indigenous fish species (NIFS). Since these systems are stressed by multiple anthropogenic pressures, it is important to build robust procedures to track NIFS distribution and spread. This study applies a multi-faceted assessment of NIFS in the lotic ecosyst...

This study aims to assess rainbow trout establishment in Greece and explores the factors of establishment success or failure. 2. We analyzed fish samples and site specific env...
Article
The increasing penetration of nano-products to the market is raising big concerns about the potential toxic and environmental effects of their constituent engineered nanoparticles (ENPs). Contradictory toxicity test results reported in the literature thus far can be explained by differences in the ENP production methods, which can strongly affect n...

BACKGROUND: this paper is based upon work from COST Action ICSHNet. Health risks related to living close to industrially contaminated sites (ICSs) are a public concern. Toxicology-based risk assessment of single contaminants is the main approach to assess health risks, but epidemiological studies which investigate the relationships between exposure...
Article
Polyurethane foam passive samplers were deployed between May 2016 and January 2017 to evaluate concentrations of polybrominated diphenyl ethers (PBDEs), selected alternative flame retardants (AFRs) and total hexabromocyclododecane (HBCDD) (sum of α-, β-, and γ-HBCDD). The PUF air samplers were deployed in semi-urban, urban, industrial and landfill...

The use of disc diffusion susceptibility tests to determine the antibacterial activity of engineered nanoparticles (ENPs) is questionable because their low diffusivity practically prevents them from penetrating through the culture media. In this study, we investigate the ability of such a test, namely the Kirby-Bauer disc diffusion test, to determi...

Brominated flame retardants (BFRs) are organic compounds containing bromine that slow down combustion and reduce fire hazard. Despite being a very diverse group of chemicals, the flame retardancy mechanism is similar for all compounds: upon heat application, they decompose, thus preventing flammable gas formation. BFRs are used in many different ap...

Conference Paper
PCBs, known endocrine disruptors, are persistent and lipophilic and they accumulate in the food web. Their metabolites, e.g., OH-PCBs, exert similar toxicological effects particularly on the thyroid system. Reportedly, OH-PCBs are excreted in feces of seals exposed to PCBs; however, some congeners with a specific structure tend to be retained in th...
