Pubblicato su Ecotoxicology and Environmental Safety uno studio che analizza l’effetto sul comportamento del lombrico terrestre E. foetida esposto a concentrazioni sub-letali di contaminanti organici nel suolo. In particolare sono stati considerati i pesticidi Clorpirifos, Imidacloprid e il tensioattivo anionico Sodio lauril etere solfato, sia come singoli composti che in miscela in diverse combinazioni (binaria, ternaria). L’applicazione dell’equazione matematica dell’Indice di Combinazione (CI), ha consentito per la prima volta di valutare l’effetto combinato di tali inquinanti sulla capacità del lombrico di evitare la zona di suolo contaminato, distinguendo il loro ruolo sinergico, antagonistico o additivo. I risultati mostrano come il test ecotossicologico basato su un end-point comportamentale, possa rappresentare un valido strumento per rilevare segnali precoci di un possibile rischio ambientale in presenza di contaminazione multipla.

Published in Ecotoxicology and Environmental Safety a study that analyzes the effect on the behavior of the earthworm E. foetida exposed to sub-lethal concentrations of organic contaminants in the soil. In particular, the pesticides Chlorpyrifos, Imidacloprid and the anionic surfactant Sodium lauryl ether sulfate were considered, both as single compounds and in mixtures with different combinations (binary, ternary). The application of the mathematical equation of the Combination Index (CI), made it possible for the first time to evaluate the combined effect of these pollutants on the ability of the earthworm to "avoid" the contaminated soil, distinguishing their synergistic, antagonistic or additive role. The results show how the ecotoxicological test based on a behavioral end-point can represent a valid tool for detecting early signs of a possible environmental risk in the presence of a multiple contamination.

Dear colleagues,
it’s time to think about your application to the next TA/RA INTERACT Call, dedicated to projects taking place in Spring/Summer 2022 and Autumn/Winter 2022-23 in Arctic bases. We are really happy to inform you that the Italian Arctic Station Dirigibile Italia of National Research Council (CNR) within the INTERACT access program can be one of your scientific destinations, making its laboratories in person (TA) and remotely (RA) accessible to researchers from countries that do not have access to the Arctic. In particular, in the area where our Station is located, Ny-Ålesund, Svalbard. To participate at the Open Call for projects, please read the call at the following link: https://eu-interact.org/accessing-the-arctic/tacall/.
Moreover, remember the following dates in order to be evaluated for this INTERACT call:
Call open: 1st October – 30th November (deadline)
Access decisions will be sent to applicants by 25th March 2022. 

We are looking forward to seeing your application.
