Micro-extraction techniques in sample preparation are gaining interest among analytical chemists as they comply with green analytical chemistry demands and ensure environmental protection and public safety. Savings in cost and time are considered as valuable benefits by using novel micro-extraction approaches in sample handling. Selectivity, sensitivity and lower detection limits are also included among the performance characteristics required to meet the legislation criteria. The target of this special issue is to present the state of art in microextraction sample preparation techniques. Modern, simple and efficient methods for preconcentration and separation are described for different analytes isolated from various matrices.

Miniaturization is a challenge thrown down to analytical chemistry. The replacement of conventional analytical systems by miniaturized alternatives during the last years is noticeable. Specifically, the miniaturization of traditional sample preparation techniques (e.g., solid-phase extraction or solvent extraction) led to the development of environmentally benign analytical methods. This book aims to provide an overview of the challenges and achievements in the application of the miniaturized sample preparation methods in analytical laboratories. It includes both theoretical and practical aspects of miniaturized sample preparation approaches and hence should be of interest to researchers, students and teachers of analytical and bioanalytical chemistry, environmental sciences and environmental engineering.

One billion people around the world rely upon fish as their primary and in many cases, their only source of protein. At the same time, increasing demand from wealthier populations in the U.S. and Europe encourages dangerous overfishing practices along coastal waters. 'Fish for Life' addresses the problem of overfishing at local, national, and global levels as part of a comprehensive governance approach - one that acknowledges the critical intersection of food security, environmental protection, and international law in fishing practices throughout the world.

"Balancing the Tides highlights the influence of marine practices and policies in the unincorporated territory of American Sāmoa on the local indigenous group, the American fishing industry, international seafood consumption, U.S. environmental programs, as well as global ecological and native concerns. Poblete explains how U.S. federal fishing programs in the post-World War II period encouraged labor based out of American Sāmoa to catch and can one-third of all tuna for United States consumption until 2009. Labeled "Made in the USA," this commodity was sometimes caught by non-U.S. regulated ships, produced under labor standards far below continental U.S. minimum wage and maximum work hours, entered U.S. jurisdiction tax free, and was sometimes caught by non-U.S. regulated ships. The second half of the book explores the tensions between indigenous and U.S. federal government environmental goals and ecology programs. Whether creating the largest National Marine Sanctuary under U.S. jurisdiction or collecting basic data on local fishing, initiatives that balanced western-based and native expectations for respectful community relationships and appropriate government programs fared better than those that did not acknowledge the positionality of all groups involved. Balancing the Tides demonstrates how western-style economics, policymaking, and knowledge building imposed by the U.S. federal government have been infused into the daily lives of American Sāmoans. American colonial efforts to protect natural resources intersect with indigenous insistence on adhering to customary principles of respect, reciprocity, and native rights in complicated ways. Experiences and lessons learned from these case studies provide insight into other tensions between colonial governments and indigenous peoples engaging in environmental and marine-based policymaking across the Pacific and the globe. Poblete's study connects the U.S.-American Sāmoa colonial relationship to global overfishing, world consumption patterns, the for-profit fishing industry, international environmental movements and studies, as well as native experiences and indigenous rights"--
