1. Deliverables 4 & 6 : refinement of pesticide risk assessment of amphibians and reptiles based on ecology and biology of wild populationsMarta Biaggini, Miguel A. Carretero, Dan Cogalniceanu, Mathieu Denoël, Christoph Leeb, Valentin Mingo, Gianpaolo Montinaro, Anamarija Žagar, 2024, končno poročilo o rezultatih raziskav Povzetek: Amphibians and reptiles are among the most threatened vertebrate taxa worldwide. About 41% (34%- 51%) of amphibians and 21% (18%-33%) of reptiles are included in the IUCN categories of threatened species (Critically Endangered, Endangered or Vulnerable; IUCN, 2021; Cox et al., 2022). In Europe, nearly a quarter of amphibians and one fifth of reptiles are threatened and a further 17% of amphibians and 13% of reptiles are included among the Near Threatened species (IUCN, 2021). There are multiple reasons why amphibians and reptiles are declining, but habitat loss and degradation, followed by chemical pollution, both mainly attributable to the expansion of intensive agriculture, are commonly indicated among the major causes of herpetofauna decline worldwide as well as in the European region (Gibbons et al., 2000; Collins and Storfer, 2003; Ribeiro et al., 2009; Todd et al., 2010; Böhm et al., 2013, Arntzen et al., 2017).

2. Multiannual trend of micro-pollutants in sediments and benthic community response in a Mediterranean lagoon (Sacca di Goro, Italy)Valentina Pitacco, Michele Mistri, Carla Rita Ferrari, Adriano Sfriso, Andrea Augusto Sfriso, Cristina Munari, 2020, izvirni znanstveni članek Povzetek: Long-term variations of ecological status in a Mediterranean coastal lagoon (Sacca di Goro, Northern Adriatic) were investigated, combining data on the concentration of surface sediment contaminants and on the structure of the macrobenthic community. The aim was to assess any amount of chemical contamination and check the response of the macrobenthic community to sediment contamination. Over the studied period, the sediments of the lagoon showed contamination by trace metals and organochlorine pesticides, with most of them exceeding the thresholds indicated by the Italian legislation in many samples. Contamination by polychlorinated dibenzodioxins and dibenzofurans (PCDD/Fs) and polycyclic aromatic hydrocarbons (PAHs) instead never exceeded the threshold. The ecological status based on the macrobenthic community, evaluated through biotic indices (AMBI and M-AMBI), fell below the Good/Moderate threshold in most samples. The results indicate a possible influence of toxic compounds in sediment on benthic organisms, but most of the variability shown by the macrobenthic community is probably due to other factors. The difficulty in establishing a cause/effect relationship was due to the co-occurrence and variability of various stressors (both natural and anthropogenic) and their interactions. The methods currently used for monitoring transitional waters thus seem insufficient to disentangle the effect of pollutants and other environmental variables on the benthos. Integrated approaches (e.g., bioaccumulation and toxicity tests) are thus needed for a more precise identification of the risk posed by a high concentration of pollutants in such environments.
