Quaternary ammonium compounds
The report "Analyses of quaternary ammonium compounds in a Nordic cooperation on screening" describes the findings of a Nordic environmental study. The quaternary ammoniums included are compounds which are used in large volumes in a variety of industrial, health sector and domestic products. The quaternary ammoniums are used to provide antistatic, antibacterial, emulating and other properties in a range of formulations like hair conditioners, cosmetics, in fabric softeners and in cleansing and disinfecting products. Some quaternary ammoniums are poorly degraded and some are highly toxic to aquatic organisms. The samples analysed were taken mainly near assumed hot-spot areas as in sewage lines and in receiving waters, but also in background areas far from anthropogenic sources. Samples include water, sludge, sediment and fish.
Selected Plasticisers and Additional Sweeteners in the Nordic Environment
The report Selected plasticisers and additional sweeteners in the Nordic Environment describes the findings of a Nordic environmental study. The study has been done as a screening, that is, it provides a snapshot of the occurrence of selected plasticisers and sweeteners, both in regions most likely to be polluted as well as in some very pristine environments. The plasticisers analysed were long chained phthalates and adipates, and the sweeteners analysed were aspartame, cyclamate and sucralose. The purpose of the screening was to elucidate levels and pathways of hitherto unrecognized pollutants. Thus the samples analysed were taken mainly from sewage lines, but also in recipients and biota, both in assumed hot-spot areas and in background areas.
Fate of Pesticides in the Atmosphere: Implications for Environmental Risk Assessment
Global pesticide use is currently estimated at approximately 2. 5 billion kg per year (Pimentel eta/. , 1998). To be effective, pesticides need to persist for a certain period of time. However, the longer their persistence, the greater the potential for transport of a fraction of the amount applied away from the target area. Pesticides are dispersed in the environment by water currents, wind, or biota. Pesticides can directly contaminate ground and surface waters by leaching, surface run-off and drift. Pesticides can also enter the atmosphere during application by evaporation and drift of small spray droplets, that remain airborne. Following application, pesticides may volatilise from the cr...
Environmental Legacies of the Copernican Universe
In Environmental Legacies of the Copernican Universe, Jean-Marie Kauth shows how counter-ecological metaphors sprung from the cosmology of the Copernican Revolution influence us still in unexpected, maladaptive ways, nurturing conceptions of the world that are not only incorrect but enabling of ecocide. She argues that grasping these underlying paradigms may help us to alter our thinking and make the radical transformations needed to counter the forward motion of our capitalist, post-industrial society.
Environmental Justice in North America
Emphasizing the voices of activists, this book’s diverse contributors examine communities’ common experiences with environmental injustice, how they organize to address it, and the ways in which their campaigns intersect with related movements such as Black Lives Matter and Indigenous sovereignty. The global COVID-19 pandemic exposed the ways in which BIPOC (Black, Indigenous, People of Color) communities and white working-class communities have suffered disproportionately from the crisis due to sustained exposure to toxic land, air, and water, creating a new urgency for addressing underlying conditions of systemic racism and poverty in North America. In addition to exploring the histori...
Monitoring Ambient Air Quality for Health Impact Assessment
A guide to the principles and methods of air quality assessment aimed at measuring population exposure to ambient air pollutants and estimating the effects on health. Addressed to policy-makers as well as scientists engaged in air quality monitoring, the book responds to the failure of most monitoring systems to provide data that are useful in estimating and managing threats to health. The need for exposure data on populations at special risk is also addressed. Throughout, emphasis is placed on methods of monitoring and modelling that are cost-effective, targeted, and appropriate to local and national conditions. The report has six chapters. The first introduces WHO activities related to air...
Transitioning to Sustainable Life below Water
The ocean plays a central role in the life and development of human kind. Besides space for navigation and trade (roughly 10 billion tons of commodities are transported across the oceans each year), the provision of biological and non-living resources is the most important service of the marine ecosystems. Yet, these ecosystems are increasingly impeded by human activities and interventions. Human and naturally induced changes in climate are buffered by the ocean, but its capacity to compensate the increase of CO2 in the atmosphere is at its limit. The increase of global temperatures and the decrease of oxygen concentration and pH are severe stressors for aquatic species and thus for the whol...
