Conservation planning has historically been restricted to planning within single realms (i.e., marine, terrestrial, or freshwater). Recently progress has been made in approaches for cross-realm planning which may enhance the ability to effectively manage processes that sustain biodiversity and ecosystem functions (e.g., connectivity) and thus minimize threats more efficiently. Current advances,…
ABSTRACT: Challenges to the use of the no observed effect concentration (NOEC) in ecotoxicology have appeared over the years, with a recent call for banning its use in favor of the x% effects concentration (ECx). This article presents an opposing view, providingmreasons for the continued use of the NOEC, and for hypothesis testing in general. Although the use of ECx values is appropriate inmma…
ABSTRACT: This article presents a method of probabilistically computing species sensitivity distributions (SSD) that is well-suited to cope with distinct data scarcity and variability. First, a probability distribution that reflects the uncertainty and variability of sensitivity is modeled for each species considered. These single species sensitivity distributions are then combined to create …
ABSTRACT: Lemna spp. are the standard test species representing aquatic macrophytes in the current risk assessment schemes for herbicides and plant growth regulators in the European Union and North America. At a Society of Environmental Toxicology and Chemistry (SETAC) 2008 workshop on Aquatic Macrophyte Risk Assessment for Pesticides (AMRAP), a Species Sensitivity Distribution (SSD) working …
ABSTRACT A large number of biological indicators have been proposed over the years for assessing soil quality. Although many of those have been applied in monitoring schemes across Europe, no consensus exists on the extent to which these indicators might perform best and how monitoring schemes can be further optimized in terms of scientific and policy relevance. Over the past decade, developme…
A number of signifi cant legal challenges impede the attribution of liability to parent or porations for the overseas operations of their subsidiaries. The multinational reach of these entities’ activities raise questions as to which forum is appropriate to hear the case, under which state’s jurisdiction an action may be brought and as to which state’s domestic law should be applied. The …
Abstract: The quest for environmental protection alongside economic development has been one of the prominent themes of political and legal discourse for several decades. This article examines the extent to which the principle of sustainable development (introduced under the Rio Declaration 1992) as a conceptual framework for balancing these competing goals has been integrated within the intern…
Abstract: Agricultural water pollution is one of the most challenging environmental problems of our times, one which remains unresolved after 13 years of the EU’s Water Framework Directive (WFD). It is argued that the WFD is not defi cient; in fact, it provides both the environmental targets and the legal impetus for Member States to reduce pollution in their waters; Member States have simpl…
Abstract: Resilience is receiving substantial traction as a concept to inform climate change and development policies and programmes. At the same time, a number of critiques have emerged that question its use as a framing concept for tackling urban climate change. This paper reflects on climate resilience and its critiques through an examination of the Asian Cities Climate Change Resilience N…
ABSTRACT: A narrow technocentric focus on a few favored ecosystem services (generally provisioning services) has led to ecosystem degradation globally, including catchment systems and their capacities to support human well‐being. Increasing recognition of the multiple benefits provided by ecosystems is slowly being translated into policy and some areas of practice, although there remains a s…
Identifying and communicating uncertainty is core to effective environmental assessment (EA). This study evaluates the extent to which uncertainties are considered and addressed in Canadian EA practice. We reviewed the environmental protection plans, follow-up programs, and panel reports (where applicable) of 12 EAs between 1995 and 2012. The types of uncertainties and levels of disclosure var…
The most significant issues facing mankind today are related to the quality of our environment. Past decisions did not always consider environmental factors as critical elements. However, current decisions made daily should reflect the importance of the environment. All environment-related issues are multidisciplinary, ranging from science and engineering to social, economic, and regulatory iss…
The treatment of contaminated land to eliminate or reduce the presence of pollutants in the contaminated site has received (and will continue to receive) considerable attention from the practicing profession. Extensive research and development are still underway in respect to the delivery of more effective (and economic) means for site decontamination. The ongoing results can be seen in the…
Natural systems for the treatment and management of municipal and industrial wastewaters and residuals feature processes that use minimal energy and minimal or no chemicals, and they produce relatively lower amounts of residual solids. This book is intended for the practicing engineers and scientists who are involved in the planning, design, construction, evaluation, and operation of wastew…
In 2001, an international panel of distinguished climate scientists announced that the world was warming at a rate without precedent during at least the last two millennia, and that warming was caused by the buildup of greenhouse gases from human activity. The story of how scientists reached that conclusion—by way of unexpected twists and turns—was the story Spencer R. Weart told in The Dis…
Like many scientists, I have always had interests far different from those of my professional life. Among them has been the challenges of dealing with the array of problems humanity faces, including how to exploit the earth's bounty without damaging it and how to deal with the conflicts between nations, for which extraordinarily destructive weapons stand at the ready. At issue are not just …
The twenty-first century is rapidly becoming the “perfect energy storm”; modern society is faced with volatile energy prices and growing environmental concerns, as well as energy supply and security issues. Today’s society was founded on hydrocarbon fuel—a finite resource that already is one of the main catalysts for international conflicts, which is likely to intensify in the future…
The Ecosystem Service Paradigm (EsSP) is increasingly a component or even an underlying principle of environmental policy, legislation and management internationally. The EsSP can be used to define links between human activities and ecosystems, and ecosystems and the services that in turn support and sustain those and other activities; this information can then be used to evaluate, justify or o…
Climate change has fully entered the public consciousness, but what to do and how fast to do it remains intensely controversial. These and other questions about how to mold transportation policy to help achieve climate goals was the focus of a high level meeting in California in July 2009. Two hundred leaders and experts were assembled from the automotive and energy industries, start-up technol…
Bringing climate change under control is one of the great historic challenges facing humanity in the 21st century. To succeed, the international community must reach an ambitious and comprehensive global agreement that provides the framework for worldwide action to keep global warming below dangerous levels. The most convincing leadership the European Union can provide is to become the …
Books have their fortunes. This book started life as a workshop organised from 14-16 June 2001 as one of the features of the KITLV 150-year jubilee. Upon the request of the board of KITLV, the topic of the workshop was prepared by a small committee consisting of Franz von Benda Beckmann, Willem Wolters and myself. The idea behind it was that the theme of the workshop should reflect both th…
Research regarding the significance and consequence of anthropogenic transformations of the earth’s land, oceans, biosphere and climate have demonstrated that, from a wide variety of perspectives, it is almost certain that humans have initiated a new geological epoch, their own. First labeled the Anthropocene by the chemist Paul Crutzen, the consideration of the merits of the Anthropocene the…
Underground infrastructure presents unique challenges for engineers because usable underground space is limited in its extent and is not easily observed or accessible. The safety, health, and welfare of the public at large are among the civil engineer’s primary concerns while designing, constructing, maintaining, and operating physical infrastructure, including underground infrastructure. Und…
The monitoring and control of bioprocesses is a challenging task. This applies particularly if the actions to the process have to be carried out in real-time. This work presents a systemfor on-linemonitoring and control of batch yeast propagation under limiting conditions based on a virtual plant operator, which uses the concept of intelligent control algorithms by means of fuzzy logic theo…
Microorganisms are used in biotechnology. They are either (i) aim and purpose of a process, e.g. with the production of single cell proteins, or (ii) mean to an end insofar as they serve as a catalyst or ‘‘factory’’ for syntheses (e.g. of products of primary and secondary metabolism, of enzymes and antibiotics) or for the degradation and detoxification of harmful organics and inorga…
This volume covers the technologies that are applied to the treatment and purification of water. Those who are generally familiar with this field will immediately embrace the subject as a treatise on solid-liquid separations. However, the subject is much broader, in that the technologies discussed are not just restricted to pollution control hardware that rely only upon physical methods of …
I would like to mention some of the changes and additions that have been included in the third edition of Wastewater Microbiology. In general, every chapter of the book has been revised (up to July 2004) to include the latest developments in the field, and I will highlight only the major ones. A review of the most important molecular techniques has been added to Chapter 1, while the most…
While this book is in its first edition, it nonetheless has a lengthy pedigree, which derives from a book entitled Understanding Our Environment: An Introduction to Environmental Chemistry and Pollution, which ran to three editions, the last of which was published in 1999. Understanding Our Environment has proved very popular as a student textbook, but changes in the way that the subject i…
Fundamentals of Environmental Chemistry, 2nd edition, is written with two major objectives in mind. The first of these is to provide a reader having little or no background in chemistry with the fundamentals of chemistry needed for a trade, profession, or curriculum of study that requires a basic knowledge of these topics. The second objective of the book is to provide a basic coverage of m…
Since this book was first published in 1972, several generations of students have become environmentally aware and conscious of their responsibilities to planet earth. Many of these environmental pioneers are now teaching in colleges and universities, and have students with the same sense of dedication and resolve that they themselves brought to the discipline. In those days, it was sometim…
By the mid-20th century, widespread concerns were being expressed for the way in which modern human populations and their industrial endeavors and products were affecting both the environment in which they lived and the planet’s wild populations and their ecosystems. Some predictions for the future were dire, and enough environmental activism developed so that some of the more conspicuous pro…
In Handbook of Water and Wastewater Treatment Plant Operations , the intent of the author is twofold. The Þrst intent is to consolidate the information and experience in waterworks and wastewater treatment plant operations that have evolved as a result of technological advances in the Þeld, and as a result of the concepts and policies promulgated by the environmental laws and the subsequent g…

Abstract The total concentration and size distribution of bioaerosols in three different types of housing (single room in shared accommodation [type I], single bedroom flat in three-storey building [type II] and two- or threebedroom detached houses [type III]) was assessed during the winter. This research was an extension of a previous study carried out in the summer. The measurement campai…
Abstract Indoor mesocosm experiments were conducted to test for potential climate change effects on the spring succession of Baltic Sea plankton. Two different temperature (D0 C and D6 C) and three light scenarios (62, 57 and 49 % of the natural surface light intensity on sunny days), mimicking increasing cloudiness as predicted for warmer winters in the Baltic Sea region, were simulated.…
Abstract The ubiquitous presence of chlorophenols (CPs) continues to be a cause of concern, owing to their recalcitrant nature. In this context, the present work investigated the degradation of model compounds, 4-chlorophenol, 2,4-dichlorophenol, 2,4,6-richlorophenol, and pentachlorophenol, by an organic oxidant, methyl ethyl ketone peroxide (MEKP) coupled with ultraviolet irradiation in b…
Abstract In this work, we address the mismatch in spatio-temporal resolution between individual, point-location based exposure and grid cell based air quality model predictions by disaggregating the grid model results. Variability of PM10 point measurements was modelled within each grid cell by the exponential variogram, using point support concentration measurements. Variogram parameters w…
Abstract This paper discusses the effects of breakwaters on the Rimini coastal environment over the last half century. Sediment cores of 50 cm thick were collected in various seasons from 2002 to 2005 and were subsampled at surface and subsurface levels at 20 inshore and offshore stations in order to take account of various freshwater and wastewater inputs. A 240-cm sediment core was colle…
Abstract In the present study, the trends in groundwater level and fifteen hydro-geochemical elements at 32 piezometric stations located in the Ardabil plain of the northwest of Iran were analyzed using the non-parametric Mann–Kendall method after removing the effect of significant lag-1 serial correlation from the respective time series by pre-whitening. The magnitudes of trends were comp…
Abstract Biomonitoring of atmospheric ammonia (NH3) concentrations is generally performed with epiphytic lichens, using species’ abundances and/or nitrogen concentration as monitoring tools. However, the potential of leaf characteristics of trees to monitor the atmospheric NH3 concentration has remained largely unexplored. Therefore, we performed a passive biomonitoring study with common …
Abstract In this research, drought in Yellow River basin has been studied by using dry spells. Three indices, including the maximum length (MxDS), mean length (MDS) and number of dry spells (NDS), and five periods (annual, winter, spring, summer and autumn) are considered. The results show that a south to north gradient for mean MxDS and MDS has been dominantly found in all periods except …
Abstract Based on the hydrologic and meteorological data in the Yarkand River Basin during 1957–2008, the nonlinear hydro-climatic process was analyzed by a comprehensive method, including the Mann–Kendall trend test, wavelet analysis, wavelet regression analysis and correlation dimension. The main findings are as following: (1) The annual runoff, annual average temperature and annual pr…
Abstract Parameter uncertainty involved in hydrological and sediment modeling often refers to the parameter dispersion and the sensitivity of the parameter. However, a limitation of the previous studies lies in that the assignment of range and specification of probability distribution for each parameter is usually difficult and subjective. Therefore, there is great uncertainty in the proces…
Abstract The response of the Baltic Sea spring bloom was studied in mesocosm experiments, where temperatures were elevated up to 6C above the present-day sea surface temperature of the spring bloom season. Four of the seven experiments were carried out at different light levels (32–202 Wh m-2 at the start of the experiments) in the different experimental years. In one further experiment,…
Abstract The objective of our study was to analyze the effects of temperature on the population dynamics of a three-species food web consisting of two prey bacteria (Pedobacter sp. and cinetobacter johnsonii) and a protozoan predator (Tetrahymena pyriformis) as model organisms. We assessed the effects of temperature on the growth rates of all three species with the objective of with four d…
Abstract During this study, we investigated the mineralogical characterization of technogenic magnetic particles (TMPs) contained in alkaline industrial dust and fly ash emitted by coal burning power plants and cement plants. The reaction of tested dust samples varied between values of pH 8 and pH 12. Their magnetic properties were characterized by measurement of magnetic susceptibility (�…
Abstract Earth and environmental variables are commonly taken to have multivariate Gaussian or heavy-tailed distributions in space and/or time. This is based on the observation that univariate frequency distributions of corresponding samples appear to be Gaussian or heavy-tailed. Of particular interest to us is the well-documented but heretofore little noticed and unexplained phenomenon tha…
