Occupational risk in a glass manufacturing industry unit

Risk assessment is one of the main pillars of the framework directive and other directives in respect of health and safety. It is also the basis of an effective management of safety and health as it is essential to reduce work-related accidents and occupational diseases. To survey the hazards eventually present in the workplaces the usual procedures are i) gathering information about tasks/activities, employees, equipment, legislation and standards; ii) observation of the tasks and; iii) quantification of respective risks through the most adequate risk assessment among the methodologies available. From this preliminary evaluation of a welding plant and, from the different measurable parameters, noise was considered the most critical. This paper focus not only the usual way of risk assessment for noise but also another approach that may allow us to identify the technique with which a weld is being performed.

Reconstruction of the recent history of a large deep prealpine lake (Lake Bourget, France) using subfossil chironomids, diatoms, and organic matter analysis: towards the definition of a lake-specific reference state

This paper presents the recent history of a large prealpine lake (Lake Bourget) using chironomids, diatoms and organic matter analysis, and deals with the ability of paleolimnological approach to define an ecological reference state for the lake in the sense of the European Framework Directive. The study at low resolution of subfossil chironomids in a 4-m-long core shows the remarkable stability over the last 2.5 kyrs of the profundal community dominated by a Micropsectra-association until the beginning of the twentieth century, when oxyphilous taxa disappeared. Focusing on this key recent period, a high resolution and multiproxy study of two short cores reveals a progressive evolution of the lake's ecological state. Until AD 1880, Lake Bourget showed low organic matter content in the deep sediments (TOC less than 1%) and a well-oxygenated hypolimnion that allowed the development of a profundal oxyphilous chironomid fauna (Micropsectra-association). Diatom communities were characteristic of oligotrophic conditions. Around AD 1880, a slight increase in the TOC was the first sign of changes in lake conditions. This was followed by a first limited decline in oligotrophic diatom taxa and the disappearance of two oxyphilous chironomid taxa at the beginning of the twentieth century. The 1940s were a major turning point in recent lake history. Diatom assemblages and accumulation of well preserved planktonic organic matter in the sediment provide evidence of strong eutrophication. The absence of profundal chironomid communities reveals permanent hypolimnetic anoxia. From AD 1995 to 2006, the diatom assemblages suggest a reduction in nutrients, and a return to mesotrophic conditions, a result of improved wastewater management. However, no change in hypolimnion benthic conditions has been shown by either the organic matter or the subfossil chironomid profundal community. Our results emphasize the relevance of the paleolimnological approach for the assessment of reference conditions for modern lakes. Before AD 1900, the profundal Micropsectra-association and the Cyclotella dominated diatom community can be considered as the Lake Bourget reference community, which reflects the reference ecological state of the lake.

Vedenlaadun parantamismahdollisuudet virtausohjauksen avulla läntisen Pien-Saimaan tapauksessa

Läntisen Pien-Saimaan vesistön alueella on ilmennyt voimakasta sinileväkukintaa vuosina 2006 - 2009. Yksi tehokas keino vähentää sinilevien määrää ja parantaa vedenlaatua, onravinnepitoisuuksien alentaminen virtausohjauksen avulla. Tästä on 70 vuoden kokemus Pien- Saimaan itäosissa, joissa Vehkataipaleen pumppaamon virta on pitänyt vedenlaadun hyvänä huolimatta vesialuetta raskaasti rasittavasta puunjalostusteollisuudesta. Diplomityössä selvitetään mahdollisuuksia toteuttaa virtauksenohjausta myös läntisen Pien-Saimaan puolella, jolloin tavoitteena on vedenlaadun paraneminen. Vedenlaadun parantamista edellyttää myös Euroopan unionin vesipuitedirektiivi. Selvityksessä tarkasteltiin virtauksenohjauksen eri toteutusvaihtoehtoja ja arvioitiin näiden vaikutuksia eri alueiden vedenlaatuun. Tämän lisäksi kartoitettiin ja arvioitiin eri vaihtoehdoista aiheutuvia riskejä. Näiden tietojen pohjalta päädyttiin suositeltaviin virtauksenohjauksen toteutusvaihtoehtoihin, joita ovat Kolhonlahti – Kolinlahti välillä toteutettu pumppaus ja mahdollisen Kutilan kanavan rakentamisen yhteydessä Kopinsalmen pumppaamo. Kolhonlahti – Kolinlahti sijaitsee Pien-Saimaan koillisosassa lähellä Rehulaa. Muista tarkastelluista kohteista saatiin yhdistelemällä suositeltavaksi vaihtoehdoksi myös Vehkataipaleen pumppaamon virran kasvattaminen yhdistettynä Kirjamoinsalmen tai Kopinsalmen pumppaamoon. Tämän lisäksi eri vaihtoehdoille laadittiin alustava kustannustarkastelu. Selvityksessä käytettyjä menetelmiä ja tuloksia voidaan soveltaa myös muihin vastaavan tyyppisiin vesistöjen kunnostushankkeisiin. Työssä on lisäksi koottu yhteen yleistietoja Pien-Saimaasta ja sen tunnetuista virtauksista.

Advanced Waste-To-Energy Cycles

The increase in environmental and healthy concerns, combined with the possibility to exploit waste as a valuable energy resource, has led to explore alternative methods for waste final disposal. In this context, the energy conversion of Municipal Solid Waste (MSW) in Waste-To-Energy (WTE) power plant is increasing throughout Europe, both in terms of plants number and capacity, furthered by legislative directives. Due to the heterogeneous nature of waste, some differences with respect to a conventional fossil fuel power plant have to be considered in the energy conversion process. In fact, as a consequence of the well-known corrosion problems, the thermodynamic efficiency of WTE power plants typically ranging in the interval 25% ÷ 30%. The new Waste Framework Directive 2008/98/EC promotes production of energy from waste introducing an energy efficiency criteria (the so-called “R1 formula”) to evaluate plant recovery status. The aim of the Directive is to drive WTE facilities to maximize energy recovery and utilization of waste heat, in order to substitute energy produced with conventional fossil fuels fired power plants. This calls for novel approaches and possibilities to maximize the conversion of MSW into energy. In particular, the idea of an integrated configuration made up of a WTE and a Gas Turbine (GT) originates, driven by the desire to eliminate or, at least, mitigate limitations affecting the WTE conversion process bounding the thermodynamic efficiency of the cycle. The aim of this Ph.D thesis is to investigate, from a thermodynamic point of view, the integrated WTE-GT system sharing the steam cycle, sharing the flue gas paths or combining both ways. The carried out analysis investigates and defines the logic governing plants match in terms of steam production and steam turbine power output as function of the thermal powers introduced.

Dinamica del fitoplancton in relazione alle variabili abiotiche con particolare attenzione alle specie dannose

Negli ultimi decenni nell’Alto Adriatico, in particolare lungo la costa dell’Emilia-Romagna, si sono verificati fenomeni eutrofici con lo svilupparsi di “red tides”, con frequenza e intensità tali da aver assunto un aspetto cronico. Da questi episodi è nata l’esigenza sia di un efficiente monitoraggio dell’area, che viene svolto dal 1976 dalla Struttura Oceanografica Daphne (ARPA), sia di ricercare e studiare i meccanismi che guidano il processo. Questa zona è sotto stretta osservazione anche nell’ambito Direttiva europea 2008/56/CE, Marine Strategy Framework Directive (MSFD), in quanto l’alto Adriatico rappresenta la zona maggiormente a rischio per i fenomeni di eutrofizzazione e di bloom algali. Il lavoro di questa tesi nasce dalla necessità di approfondire diversi aspetti sollevati dalla MSFD che non vengono soddisfatti da una normale attività di monitoraggio. La frequenza e l’enorme mole di dati raccolti spesso non permette nè di riunire insieme per un unico sito tutti i parametri biotici e abiotici indicativi dello stato dell’ambiente, né di fare elaborazioni statistiche approfondite. Per fare questo sono state condotte in due siti prospicienti la località di Marina di Ravenna (costa emiliano-romagnola): DIGA SUD e GEOMAR, distanti rispettivamente 1.5 Km e 12 Km dalla costa, analisi quali-quantitative dei popolamenti fitoplanctonici presenti e concomitanti analisi dei parametri chimico-fisici (nutrienti, temperatura e salinità) dell’acqua. Il campionamento bimensile è iniziato ad aprile del 2013 ed è terminato ad ottobre dello stesso anno. Dai dati ottenuti dalle suddette analisi, avvalendosi di diversi strumenti statistici, si è cercato di capire se c’è differenza fra i due siti oggetto di studio in termini di variabili abiotiche ambientali e di popolazione fitoplanctonica dovuta ad effetto geografico (distanza dalla costa). Inoltre si è cercato di individuare come le variabili ambientali vadano ad influenzare la distribuzione dei diversi taxa fitoplanctonici e di segnalare l’eventuale presenza di specie microalgali potenzialmente tossiche e/o dannose.

European legislation and implementation measures in the management of construction and demolition waste.

The intense activity in the construction sector during the last decade has generated huge volumes of construction and demolition (C&D) waste. In average, Europe has generated around 890 million tonnes of construction and demolition waste per year. Although now the activity has entered in a phase of decline, due to the change of the economic cycle, we don’t have to forget all the problems caused by such waste, or rather, by their management which is still far from achieving the overall target of 70% for C&D waste --excludes soil and stones not containing dangerous substances-- should be recycled in the EU Countries by 2020 (Waste Framework Directive). But in fact, the reality is that only 50% of the C&D waste generated in EU is recycled and 40% of it corresponds to the recycling of soil and stones not containing dangerous substances. Aware of this situation, the European Countries are implementing national policies as well as different measures to prevent the waste that can be avoidable and to promote measures to increase recycling and recovering. In this aspect, this article gives an overview of the amount of C&D waste generated in European countries, as well as the amount of this waste that is being recycled and the different measures that European countries have applied to solve this situation.

Energy efficiency: the ever neglected priority of the European energy strategy. Egmont Paper No. 66, June 2014

Summary. Energy saving has been a stated policy objective of the EU since the 1970s. Presently, the 2020 target is a 20% reduction of EU energy consumption in comparison with current projections for 2020. This is one of the headline targets of the European Energy Strategy 2020 but efforts to achieve it remain slow and insufficient. The aim of this paper is to understand why this is happening. Firstly, this paper examines the reasons why public measures promoting energy efficiency are needed and what form these measures should optimally take (§ 1). Fortunately, over the last 20 years, much research has been done into the famous ‘energy efficiency gap’ (or ‘the energy efficiency paradox’), even if more remains to be done. Multiple explanations have been given: market failures, modelling flaws and behavioural obstacles. Each encompasses many complex aspects. Several types of instruments can be adopted to encourage energy efficiency: measures guaranteeing the correct pricing of energy are preferred, followed by taxes or tradable white certificates which in turn are preferred to standards or subsidies. Information programmes are also necessary. Secondly, the paper analyzes the evolution of the different programmes from 2000 onwards (§ 2). This reveals the extreme complexity of the subject. It deals with quite diverse topics: buildings, appliances, public sector, industry and transport. The market for energy efficiency is as diffuse as energy consumption patterns themselves. It is composed of many market actors who demand more efficient provision of energy services, and that suppliers of the necessary goods and know-how deliver this greater efficiency. Consumers in this market include individuals, businesses and governments, and market activities cover all energy-consuming sectors of the economy. Additionally, energy efficiency is the perfect example of a shared competence between the EU and the Member States. Lastly, the legal framework has steadily increased in complexity, and despite the successive energy efficiency programmes used to build this framework, it has become clear that the gap between the target and the results remains. The paper then examines whether the 2012/27/EU Directive adopted to improve the situation could bring better results. It briefly describes the content of this framework Directive, which accompanies and implements the latest energy efficiency programme (§ 3). Although the Directive is technically complex and maintains nonbinding energy efficiency targets, it certainly represents an improvement in several aspects. However, it is also saddled with a multiplicity of exemption clauses and interpretative documents (with no binding value) which weaken its provisions. Furthermore, alone, it will allow the achievement of only about 17.7% of final energy savings by 2020. The implementation process, which is essential, also remains fairly weak. The paper also gives a glimpse of the various EU instruments for financing energy efficiency projects (§ 4). Though useful, they do not indicate a strong priority. Fourthly, the paper tries to analyze the EU’s limited progress so far and gather a few suggestions for improvement. One thing seems to remain useful: targets which can be defined in various ways (§ 5). Basically, all this indicates that the EU energy efficiency strategy has so far failed to reach its targets, lacks coherence and remains ambiguous. In the new Commission’s proposals of 22 January 2014 – intended to define a new climate/energy package in the period from 2020 to 2030 – the approach to energy efficiency remains unclear. This is regrettable. Energy efficiency is the only instrument which allows the EU to reach simultaneously its three targets: sustainability, competitiveness and security. The final conclusion appears thus paradoxical. On the one hand, all existing studies indicate that the decarbonization of the EU economy will be absolutely impossible without some very serious improvements in energy efficiency. On the other hand, in reality energy efficiency has always been treated as a second zone priority. It is imperative to eliminate this contradiction.

Immunomodulating effects of environmentally realistic copper concentrations in Mytilus edulis adapted to naturally low salinities, link to supplementary material

The monitoring of organisms' health conditions by the assessment of their immunocompetence may serve as an important criterion for the achievement of the Good Environmental Status (GES) as defined in the Marine Strategy Framework Directive (EU). In this context, the complex role of natural environmental stressors, e.g. salinity, and interfering or superimposing effects of anthropogenic chemicals, should be carefully considered, especially in scenarios of low to moderate contamination. Organisms from the Baltic Sea have adapted to the ambient salinity regime, however energetically costly osmoregulating processes may have an impact on the capability to respond to additional stress such as contamination. The assessment of multiple stressors, encompassing natural and anthropogenic factors, influencing an organisms' health was the main aim of the present study. Immune responses of Mytilus edulis, collected and kept at natural salinities of 12 per mil (LS) and 20 per mil (MS), respectively, were compared after short-term exposure (1, 7 and 13 days) to low copper concentrations (5, 9 and 16 µg/L Cu). A significant interaction of salinity and copper exposure was observed in copper accumulation. LS mussels accumulated markedly more copper than MS mussels. No combined effects were detected in cellular responses. Bacterial clearance was mostly achieved by phagocytosis, as revealed by a strong positive correlation between bacterial counts and phagocytic activity, which was particularly pronounced in LS mussels. MS mussels, on the other hand, seemingly accomplished bacterial clearance by employing additional humoral factors (16 µg/L Cu). The greatest separating factor in the PCA biplot between LS and MS mussels was the proportion of granulocytes and hyalinocytes while functional parameters (phagocytic activity and bacterial clearance) were hardly affected by salinity, but rather by copper exposure. In conclusion, immune responses of the blue mussel may be suitable and sensitive biomarkers for the assessment of ecosystem health in brackish waters (10-20 per mil S).

Project scoping for lessons learnt to apply to the Celtic Seas marine sub-region

This report involves a formal scoping exercise to identify lessons from a wide range of previous and current project and initiative experiences at the national, regional seas, European and global levels. An inventory of 77 projects and initiatives that are relevant with regard to the key activities proposed by the Celtic Seas Partnership has been compiled, as well as a short-list of 23 of the most pertinent projects, lessons learnt and contact names. This report has identified a number of synergies and collaborative opportunities from other project and initiatives in the Celtic Seas and beyond. It provides a strong starting point to clarify to stakeholders the uniqueness of the Celtic Seas Partnership project and delivers a sound baseline for the other preparatory actions (A2 Stakeholder Mapping and A3 Baseline Analysis for Marine Strategy Framework Directive Implementation) and the implementation actions. Furthermore, this report helps to avoid duplication of effort during the life-span of the project by highlighting what information pertaining to the Celtic Seas MSFD sub-region already exists.

Disability Discrimination: Obesity and the Court of Justice of the European Union’s decision in Karsten Kaltoft v Billund Kommune Case C-354/13 ECJ

Walker and Karsten are two important decisions in disability discrimination law – not solely on the basis of their legal and practical repercussions for the United Kingdom (UK) and European Union (EU), respectively, but because they capture the very ideological spirit of domestic and European anti-discrimination legislation. The former directly relates to disability discrimination in the UK and the entire EU is feeling the brunt of the Court of Justice of the European Union’s decision in the latter. This article explores the impact of both these decisions and to what extent the obese or those suffering from a functional overlay are now protected from being discriminated against by the Framework Directive 2000/78 and the United Kingdom’s Equality Act 2010.
