Một thuộc địa của ong mật là một hiệu quả thiết bị lấy mẫu môi trường cho dễ bay hơi và bán hợp chất hữu cơ dễ bay hơi (VOC và SVOCs) trong một hệ sinh thái phức tạp. Trong sáu năm qua, chúng tôi có Phát triển một giải hấp nhiệt / sắc ký khí / khối phổ (TD / GC / MS) sử dụng kỹ thuật phân tử carbon có sẵn sàng ống thương phẩm bán ra màn hình cho các tổ ong bầu khí quyển hiện diện của chất VOC và SVOCs.

Alnasser Summary A colony of honey bees is an effective environmental sampling device for volatile and semi-volatile organic compounds VOCs and SVOCs in a complex ecosystem setting. Over the past six years we have developed a thermal desorption gas chromatography mass spectrometry TD GC MS technique using commercially available carbon molecular sieve tubes to screen beehive atmospheres for the presence of VOCs and SVOCs. Hive air is withdrawn at about dm3 min through a small copper tube inserted between frames in the center of the beehive. Besides detecting the compounds normally released by honey bee physiology hive stores and hive construction components we also see a broad range of compounds that are environmental contaminants. These fall into categories of fossil fuel constituents industrial solvents pesticides and explosives. Hives can be deployed over regional landscapes or clustered near known contaminated sites to yield useful guidance on clean-up prioritization. More recent work introduces xenobiotic VOC taggants to feeders as an aid in studying the foraging pattern of bees. Introduction Honey bees Apis mellifera L. are excellent monitors of environmental quality 1-3 . They have been employed as in situ monitors of elemental contaminant exposure and associated effects for more than twenty years. Comparative case histories and guidelines for the use of honey bees as sentinel species have been published 2 4-9 . More recently the use of bees has been extended to include real-time monitoring of colony condition . flight activity temperature regulation in the brood nest and routine monitoring for volatile and semivolatile organic contaminants in studies for the US Army at Aberdeen Proving Ground Maryland 10-14 . In the process of monitoring organic contaminants it has also been necessary to characterize the complex background of organic
