Book excerpt: European Union (EU) and international policies have been tackling water and environmental pollution for nearly 50 years. Gross chemical pollution, exemplified by 'dead rivers', has been successfully addressed in many cases. However, in its recent report European waters — Assessment of status and pressures 2018, which was based on data from Member States on the implementation of the Water Framework Directive (2000/60/EC) (WFD), the European Environment Agency (EEA) found that only 38 % of EU surface water bodies are in good chemical status. 46 % are failing to achieve good chemical status and 16 % are in unknown chemical status (EEA, 2018a). Chemical status of surface waters under the WFD is assessed against a relatively short list of historically important pollutants. The concentration of a substance in the water is compared with an environmental quality standard (EQS) set for a single substance. This approach has been used for many years and fits well with regulations seeking to control chemicals at source. Most failures in the chemical status of surface waters can be attributed to three groups of substances, all of which are persistent and widely distributed: mercury and its compounds, PAHs (polycyclic aromatic hydrocarbons) and pBDEs (polybrominated diphenylethers). Through an analysis of the monitoring and emissions data reported by countries, specific actions can be determined that target these priority substances. Action should be taken to reduce all emissions of these substances, in particular, atmospheric emissions. We need to improve understanding of the pathways taken by pBDEs and the pressures causing PAHs to pollute surface waters. Monitoring under the WFD provides important feedback on the effectiveness of chemical source control. However, our understanding of the complex interactions between chemicals and living organisms has greatly increased over the last 20 years. At concentrations lower than those that kill directly, harmful chemicals may exert more subtle effects on organisms, for example by limiting the organism's ability to reproduce. Concern has been raised about the 'cocktail effect', whereby mixtures of substances that may individually be present at harmless concentrations may combine in complicated ways to affect health. New approaches have been developed to measure these effects in effluents and the environment, and these offer ways to assess the potential risks presented by mixtures while still providing information on the types of chemicals causing these risks. This causal information is important for the implementation of effective measures against pollution. From the reported data, we can see that for a number of priority substances, measures seem to have been effective in preventing the entry of these chemicals into surface waters. This success should be welcomed and we should learn the lessons around which approaches work and which do not. However, there are many more chemicals in the environment about which we know little. The challenge presented by chemical mixtures highlights the need to fundamentally review which chemicals we use and how we use them. For the longer term, moving to a less toxic, safer and more sustainable future requires the development of approaches that avoid the use of hazardous substances. Emissions data on pollutants as reported in Europe (for the WFD, the European Pollutant Release and Transfer Register (E-PRTR) or the reporting of the Water Information System for Europe — State of the Environment (WISE-SoE)) can give an important overview on emissions, the impact of measures and trends. However, such data are incomplete and inconsistent and too often exclude diffuse sources. Improvements to our understanding of emissions could be achieved by streamlining of emissions reporting requirements, towards securing robust data satisfying all European emissions to water reporting requirements, and improving the monitoring, modelling and reporting of diffuse sources, to ensure that pressures are correctly understood and measures can be appropriately targeted.
Download or read book Deep Eutectic Solvents written by Diego J. Ramón and published by John Wiley & Sons. This book was released on 2020-01-13 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: A useful guide to the fundamentals and applications of deep eutectic solvents Deep Eutectic Solvents contains a comprehensive review of the use of deep eutectic solvents (DESs) as an environmentally benign alternative reaction media for chemical transformations and processes. The contributors cover a range of topics including synthesis, structure, properties, toxicity and biodegradability of DESs. The book also explores myriad applications in various disciplines, such as organic synthesis and (bio)catalysis, electrochemistry, extraction, analytical chemistry, polymerizations, (nano)materials preparation, biomass processing, and gas adsorption. The book is aimed at organic chemists, catalytic chemists, pharmaceutical chemists, biochemists, electrochemists, and others involved in the design of eco-friendly reactions and processes. This important book: -Explores the promise of DESs as an environmentally benign alternative to hazardous organic solvents -Covers the synthesis, structure, properties (incl. toxicity) as well as a wide range of applications -Offers a springboard for stimulating critical discussion and encouraging further advances in the field Deep Eutectic Solvents is an interdisciplinary resource for researchers in academia and industry interested in the many uses of DESs as an environmentally benign alternative reaction media.

Download or read book Industrial Chemicals written by G. Agam and published by Newnes. This book was released on 2012-12-02 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: The special world of industrial chemistry is illuminated in this text. Issues such as naming and classification of chemicals, safety, formulations and specifications, information and patents are treated. Process-related topics are discussed, such as scaling-up, equipment selection, construction materials, environmental impact and waste minimization. Aspects which fall in between the traditional disciplines of chemistry and chemical engineering are covered, which are so critical for the development of a successful industrial process, and the awareness of which avoids pitfalls in industrial research and development. Case studies are given, and special appendices provide useful information for the industrial chemist or student.The book is aimed at industrial chemists and engineers, and at students in those faculties, intending to pursue this field in industry. Marketing and purchasing staff will also find this text valuable.

Available in PDF, EPUB and Kindle. Book excerpt: The European chemical industry is the largest in the world but it is by no means the only source of occupational exposure to chemical hazards, because chemical products are both used and are bi-products in many diverse forms of work. This book is a study of strategic approaches to managing the risks of working with hazardous substances in Europe.
