The disinfection of drinking water is an important public health service that generates high quality, safe and palatable tap water. The disinfection of drinking water to reduce waterborne disease was an outstanding public health achievement of the 20 th *** unintended consequence is the reaction of disinfectants with natural organic matter,anthropogenic contaminants and bromide/iodide to form disinfection by-products（dBPs）.A large number of dBPs are cytotoxic, neurotoxic, mutagenic, genotoxic, carcinogenic and teratogenic. Epidemiological studies demonstrated low but significant associations between disinfected drinking water and adverse health effects. The distribution of dBPs in disinfected waters has been well defined by advances in high precision analytical chemistry. Progress in the analytical biology and toxicology of dBPs has been *** objective of this review was to provide a detailed presentation of the methodology for the quantitative, comparative analyses on the induction of cytotoxicity and genotoxicity of103 dBPs using an identical analytical biological platform and endpoints. A single Chinese hamster ovary cell line was employed in the assays. The data presented are derived from papers published in the literature as well as additional new data and represent the largest direct quantitative comparison on the toxic potency of both regulated and emerging *** data may form the foundation of novel research to define the major forcing agents of dBP-mediated toxicity in disinfected water and may play an important role in achieving the goal of making safe drinking water better.

因为环保涉及到安全利用煤炭问题,选煤对环境的贡献就变得更为重要。公众和环保方面更为关心的是有毒元素的排放。大量研究工作发现,元素砷、镉、铅、铜、汞、镍、硒、锰和锌对人类的健康和环境构成潜在的严重威胁。一、微量元素在煤中的含量在美国,煤炭里微量元素含量随着煤田不同有相当大的变化,包括北部大平原、洛基山脉、内陆盆地、海湾和阿巴拉契亚山脉煤田,表1列举了本文所涉及到的9种微量元素在各煤田的平均含量。表1 数据表明,锰和锌元素的含量最高,其次是铜、砷、铅和镍,再次是镉和硒,汞最少。一般说来,阿巴拉契亚山脉。

Enteroenteric intussusception is a condition in which full-thickness bowel wall becomes telescoped into the lumen of distal bowel. In adults, there is usually an abnormality acting as a lead point, usually a Meckels＇ diverticulum, a hamartoma or a tumour. duodeno- duodenal intussusception is exceptionally rare because the retroperitoneal situation fixes the duodenal wall. The aim of this report is to describe the first published case of this condition. A patient with duodeno-duodenal intussusception secondary to an ampullary lesion is reported. A 66 year-old lady presented with intermittent abdominal pain, weight loss and anaemia. Ultrasound scanning showed dilated bile and pancreatic ducts. CT scanning revealed intussusception involving the full-thickness duodenal wall. The lead point was an ampullary villous adenoma. Congenital partial （type r[） malrotation was found at operation and this abnormality permitted excessive mobility of the duodenal wall such that intussusception was possible. This condition can be diagnosed using enhanced CT. Intussusception can be complicated by bowel obstruction, ischaemia or bleeding, and therefore the underlying cause should be treated as soon as possible.

作者： Matthews j d Vanderstricht j P(Rhone-Poulenc Rare Earths and Gallium) Rhone-Poulenc Rare Earths and Gallium La Rochelle France

The first production of rare earths by the business now called Rhone Poulenec Rare Earths and Gallium was at the tum of the ceritury in Normandy, northern France under the name Societedes Terres Rares. Manufacturing of rare earths started at La Rochelle on the west coast of France in 1946 and at Freeport in Texas in 1981 . Since 1988 we have maintained a production unit in japan also, originally in cooperation with Sumitomo Metal Mining and more recently with Santoku Metal Industries.
