Gần đây, tập trung phân tích môi trường đã chuyển từ các chất gây ô nhiễm cổ điển, chẳng hạn như các chất ô nhiễm hữu cơ liên tục, đối với "chất gây ô nhiễm mới nổi" phát hiện gần đây trong nhiều chất gây ô nhiễm môi trường mới nổi được định nghĩa là hợp chất không được bao phủ bởi quy định hiện hành chất lượng nước, đã không được nghiên cứu trước đây, và được cho là có tiềm năng các mối đe dọa đến hệ sinh thái môi trường và sức khỏe con người và an toàn. Đặc biệt, các hợp. | 2 Advances in the Analysis of Pharmaceuticals in the Aquatic Environment Sandra Pérez and Damià Barceló Contents Multiresidue Determination of Drugs According to Their Analgesics and Antiinflammatory Antiepileptics Blood Lipid Regulators and Psychiatric Antitumoral Cardiovascular Drugs P-Blockers and X-Ray Contrast Agents . 73 Drugs of Other Conclusion. 75 Acknowledgments. 76 INTRODUCTION Recently the focus of environmental analysis has shifted from the classic contaminants such as the persistent organic pollutants toward the emerging contaminants detected recently in many environmental Emerging contaminants are defined as compounds that are not currently covered by existing regulations of water quality have not been previously studied and are thought to be potential threats to environmental ecosystems and human health and safety. In particular the compounds that are being addressed include pharmaceuticals drugs of abuse and personal-care The high water solubility of these organic compounds makes them mobile in the aquatic media hence they can potentially infiltrate the soil and then reach groundwater. Eventually these compounds may find their way into the drinking water supplies. In recent years the increasing use of drugs in farming aquaculture and human health has become a growing public concern because of their potential to cause undesirable ecological and human health effects. The main concern regarding 53 2008 by Taylor Francis Group LLC 54 Fate of Pharmaceuticals in the Environment and in Water Treatment Systems pharmaceuticals is that they are being introduced continuously into water bodies as pollutants and due to their biological activity this can lead to adverse effects in aquatic ecosystems and potentially .
