In past years, communication activities have become increasingly important in the environment and health domain, considering the concurrent developments of social media and scientific citizenship that contributed changes in legislation and culture. Communication is particularly crucial where an environmental hazard is present, as in the case of high risk environmental and health risk areas. The project “International Center of Advanced Study in Environment, Ecosystem and Human Health” (CISAS), carried out by the Italian National Research Council, covers multiple research activities, from ecology to biology and medical sciences, from epidemiology to social sciences and communication. Three different studies based on human biomonitoring and a birth cohort study are currently in progress in the project locations, together with studies on the environmental fate of pollutants. A clear, accurate and respectful communication of study protocols and results represents a priority to produce comprehensible information available for policy makers, citizens, and stakeholders. This paper describes the multiple external and internal communication activities planned in the framework of the CISAS project as an example of promotion of knowledge in the society at large and improvement of risk management in the environmental health domain.

It is widely accepted that phenotypic traits can be modulated at the epigenetic level so that some conditions can affect the progeny of exposed individuals. To assess if the exposure of adult animals could result in effects on the offspring, the Mediterranean sea urchin and its well-characterized gene regulatory networks (GRNs) was chosen as a model. Adult animals were exposed to known concentrations of zinc and cadmium (both individually and in combination) for 10 days, and the resulting embryos were followed during the development. The oxidative stress occurring in parental gonads, embryo phenotypes and mortality, and the expression level of a set of selected genes, including members of the skeletogenic and endodermal GRNs, were evaluated. Increased oxidative stress at F₀, high rates of developmental aberration with impaired gastrulation, in association to deregulation of genes involved in skeletogenesis (dri, hex, sm50, p16, p19, msp130), endodermal specification (foxa, hox11/13b, wnt8) and epigenetic regulation (kat2A, hdac1, ehmt2, phf8 and UBE2a) occurred either at 24 or 48 hpf. Results strongly indicate that exposure to environmental pollutants can affect not only directly challenged animals but also their progeny (at least F₁), influencing optimal timing of genetic programme of embryo development, resulting in an overall impairment of developmental success.
