This book is the first volume of two volumes on cyclodextrins published in the series Environmental Chemistry for a Sustainable World. After a brief description of the cyclodextrin fundamentals, the first chapter by Grégorio Crini et al. provides an overview of cyclodextrin research during the last 5 years. The second chapter by Michal Řezanka discusses the synthesis of novel cyclodextrin systems by selective modifications. Then Eric Monflier et al. describes the synthesis of nanostructured porous materials based on cyclodextrins, and applications in heterogeneous catalysis and photocatalysis. The use of thermal analyses for assessing cyclodextrin inclusion complexes is reviewed in chapter 4 by Daniel Hădărugă et al. Experimental methods for measuring binding constants of cyclodextrin inclusion compounds are presented by David Landy. The second volume reviews cyclodextrin applications in medicine, food, environment and liquid crystals

This book presents advanced methods to analyse and clean pollutants, such as nanotechnology to treat water, techniques to remediate building materials, and bioindicators. It is very important that the understanding of these methods are brought to the attention of scientists, as cities and ecosystems are still polluted by toxic compounds despite efforts to clean the planet

This book details first the chemistry of hydrogen production from biomass. Solutions to the CO2issue are given in three chapters, which describe CO2 photo catalytic reduction, CO2 sequestration in terrestrial biomass, and plants as renewable fuels. Further chapters review the selenium cycle in ecosystems, advanced processes to treat water and ecological ways to dye textiles. Society growth during the last century has almost entirely relied on the carbon economy, which is the use of fossil fuels for energy and materials. The carbon economy has provided and will still provide many benefits. However, the increasing use of fossil fuels is partly responsible for the increase of atmospheric CO2concentrations and in turn, global warming. There is therefore an urgent need for cleaner fuels such as hydrogen, as well as a need for a carbon neutral economy where each emitted CO2molecule is fast sequestered in plants, algae, soils, sub soils and sediments.

Pollution has no borders. This popular 70's saying from early ecologists is surprisingly still true nowadays despite overwhelming scientific evidence and public awareness of the occurrence of artificial toxic substances in water, food, air, living organisms and the environment. This book presents advanced reviews on pollutant occurrence, transfer, toxicity and remediation. The chapter on school air quality by Dambruoso et al. highlights the overlooked health issue of airborne pollutants in buildings. Children are particularly threatened because they spend 90% of their time indoors, even in summer. The chapter on industrial wastewater pollutants by Dsikowitzky and Schwarzbauer reviews pollutants from textile, petrochemical, paper, tire, chemical and pharmaceutical plants. The authors describe advanced analytical methods and ecotoxicity tests. Industrial pollutants include dioxins and furans that are also reviewed in the chapter by Mudhoo et al. The chapter on fly ash by Gianoncelli et al. presents many techniques to treat fly ash and, in turn, decrease pollutant concentrations. The authors also explain that fly ash can be recycled in agriculture, buildings and geopolymers. The chapter on antifouling paints used for ship protection, by Sousa et al., highlights the occurrence of toxic organotins in human organs such as heart, liver and breast milk. The chapter on surfactants by Rebello et al. focuses on safety concerns for humans and the ecosystems. Remediation techniques and green surfactants are presented. The chapters on toxic metals by Nava-Ruiz and Mendez-Armenta, Abarikwu and Risti? et al. describe sources, monitoring and diseases induced by lead, mercury, cadmium and thallium. The chapter on carcinogenic nitrosamines by Li et al. presents techniques and materials such as zeolites to remediate liquids and smoke containing nitrosamines.

Environmental chemistry is a new, fast developing science aimed at deciphering fundamental mechanisms ruling the behaviour of pollutants in ecosystems. Applying this knowledge to current environmental issues leads to the remediation of environmental media, and to new, low energy, low emission, sustainable processes. This book describes the state-of-the-art advances regarding the pollution of water, soils, atmosphere, food and living organisms by toxic metals, fossil fuels, pesticides and other organic pollutants. Furthermore, the eco-toxicology section presents novel bio-assays to assess the toxicity of various pollutants such as dioxins and endocrine disrupters within complex media. The green chemistry section highlights novel chemical reactions based upon environmentally friendly conditions. The analytical chemistry section describes very sensitive methods which trace the fate of pollutants in complex ecosystems.

Merci, Eric ; International audience ; In this article, we show that the chaos and urgency induced by the coronavirus disease 2019 (COVID-19) pandemic has led to massive fossil fuel-derived plastic production, largely ignoring recent environmental policies. Solutions for a sustainable and circular economy require radical innovations, consumer education and most importantly political willingness.
