Water quality integrated system: A strategic approach to improve bathing water management

In the Adriatic Sea, massive rainfall events are causing flooding of rivers and streams, with severe consequences on the environment. The consequent bacterial contamination of bathing water poses public health risks besides damaging tourism and the economy. This study was conducted in the framework of WATERCARE, an EU Interreg Italy-Croatia Project, which aims at reducing the impact of microbial contamination on Adriatic bathing water due to heavy rainfall events drained in the local sewage network and; enhancing the quality of local waters; and providing support for the decision-making processes regarding the management of bathing water in line with EU regulations. The study involved the development of an innovative water quality integrated system that helps meet these objectives. It consists of four components: a real time hydro-meteorological monitoring system; an autosampler to collect freshwater samples during and after significant rainfall events; a forecast system to simulate the dispersion of pollutants in seawater; and a real-time alert system that can predict the potential ecological risk from the microbial contamination of seawater. The system was developed and tested at a pilot site (Fano, Italy). These preliminary results will be used to develop guidelines for urban wastewater and coastal system quality assessments to contribute to develop policy actions and final governance decisions.

Overcoming the dichotomy of implementing societal flood risk management while conserving instream fish habitat - A long-term study from a highly modified urban river

Flood Risk Management (FRM) is often essential to reduce the risk of flooding to properties and infrastructure in urban landscapes, but typically degrades the habitats required by many aquatic animals for foraging, refuge and reproduction. This conflict between flood risk management and biodiversity is driven by conflicting directives, such as the EU Floods and Water Framework Directives, and has led to a requirement for synergistic solutions for FRM that integrate river restoration actions. Unfortunately, ecological monitoring and appraisal of combined FRM and river restoration works is inadequate. This paper uses a case study from the River Don in Northern England to evaluate the effects of the FRM and subsequent river restoration works on instream habitat and the associated fish assemblage over an 8-year period. Flood risk management created a homogeneous channel but did not negatively affect fish species composition or densities, specifically brown trout. Densities of adult brown trout were comparable pre and post-FRM, while densities of juvenile bullhead and brown trout increased dramatically post FRM. River restoration works created a heterogeneous channel but did not significantly improve species composition or brown trout density. Species composition post-river restoration works returned to that similar to pre-FRM over a short-term period, but with improved numbers of juvenile bullhead. Although habitat complexity increased after river restoration works, long-term changes in species composition and densities were marginal, probably because the river reset habitat complexity within the time framework of the study.

Regulatory frameworks for mobile medical applications

A mobile application (app) is a software program that runs on mobile communication devices such as a smartphone. The concept of a mobile medical app has gained popularity and diffusion but its reference regulatory context has raised discussion and concerns. Theoretically, a mobile app can be developed and uploaded easily by any person or entity. Thus, if an app can have some effects on the health of the users, it is mandatory to identify its reference regulatory context and the applicable prescriptions.

Optimization of an "in situ" subtidal rocky-shore sampling strategy for monitoring purposes

This study compared 2 standardized protocols to monitor subtidal rocky shores. We tested 2 sampling methods (temporal unit and quadrat) to assess the efficiency of extracting biota parameters (diversity, abundance, and biomass) of macroalgae, Mollusca, and Porifera with respect to time-cost and the number of sampling units. Species richness and occurrence of rocky subtidal habitats were better described by visual censuses than by quadrats. The same estimated richness was provided by the 2 methods. The association of a visual census and a quadrat was the most efficient way for responding to the requirements. A minimum of 5 sampling units per discrete area is recommended for accurately describing habitats. Then, we tested the sensitivity of the proposed protocol on the Bizeux Islet to study the variations of community structures according to depth and station. Based on the results, recommendations for monitoring purposes have been proposed according to European directives.

CEN Standards for Testing and Certifying Personal Protective Equipment-Status Quo and Deficiencies: Examples

By establishing the internal market, the European Union intended to create an area in which safety and health at work are guaranteed. For this purpose, a series of directives was passed. The EC Directive 89/686/EEC "Approximation of the laws of the Member States relating to personal protective equipment" is of particular interest to the manufacturers of personal protective equipment (PPE). On the European level, harmonized standards, that put these basic health and safety requirements into more concrete terms have to be available. The European Standardizing Committee (CEN) is charged with the elaboration of European standards. A total of 176 standards relating to personal protective equipment have to be setup; 57 of them are available at present. All CEN members are obliged to transpose them without modification into national standards. Formerly existing national standards have to be withdrawn. Existing European standards sometimes show deficiencies regarding the specification of requirements according to Directive 89/686/EEC: the standardization of PPE for special fields of application and insufficient harmonization of provisions for different PPE serving the same protective purpose. Test methods are not always described precisely enough.
