Arctic atmospheric pollution is now a major international issue. This volume presents the most authoritative review of this increasingly important subject for an audience of both scientists and administrators concerned with worldwide, as well as polar, pollution problems. Arctic Air Pollution is an edited collection of papers, first presented at a conference helo as the Scott Polar Research Institute in Cambridge in 1985. Building on foundations established at earlier meetings, this volume examines the problem of Arctic air pollution in an integrated, multidisciplinary fashion, with contributions from leading authorities in chemistry, ecology, climatology and epidemiology. To chemists, physicists and climatologists, it presents scientific problems. Ecologists are concerned with environmental threats; medical researchers with potential threats to human health. International lawyers and administrators are concerned with the legal implications of pollutants transferred across continents. Overall hangs the major question; can man-made pollution affect the delicate energy balance of the Arctic, and precipitate major climatic change worldwide?

By the turn of the century China had reaffirmed its position as one of the world's leading military powers. With much importance attached to fleet renewal; the People's Liberation Army Air Force (PLAAF) and the Naval Aviation are fielding new types, emphasis shifting from local derivatives of Russian or western types to indigenously developed aircraft and helicopters. The book focuses on the current PLAAF/PLANAF order of battle and describes the most advanced aircraft types currently in service or due to enter service. Among the many aircraft reviewed in this volume are the Chengdu J-10 single-engined fourth-generation fighter in service since 2003, fifth-generation fighters like the twin-engined, tail-first Chengdu J-20, and the smaller Shenyang J-31 fifth-generation light fighter. Deliveries of Xian H-6K missile carriers, the Chinese version of the Tupolev Tu-16 bomber, are continuing, the H-6N with in-flight refuelling capability, entering service in 2019. Transport aviation is not forgotten either. China has also been building an aircraft carrier fleet equipped with the Shenyang J-15 Flying Shark shipboard fighter derived from the Sukhoi Su-33. The latest addition to the Chinese Army Aviation's arsenal is the Harbin Z-20 medium utility helicopter which looks like the Sikorsky S-70 Black Hawk. Numbers of the CAIC Z-10 attack helicopter and the lighter Harbin Z-19 attack helicopter are also now operational. Unmanned aerial vehicles are also reviewed in this comprehensive survey
