Elevated levels of selenium (maximum 200 mg/kg) and tellurium (maximum 11 mg/kg) are reported in topsoils (<5 cm) from around a long-established nickel refinery at Clydach in the Lower Swansea Valley, UK. Se and Te are correlated with each other and when these data are plotted as contour diagrams they show a concentric pattern centred on the refinery site. The origin of the Se and Te contamination is investigated. A review of the changes in the refinery practices at the site is presented and used to link the soil contamination to industrial pollution which took place over 80 years ago. The most recent air quality data available cannot rule out some Se contamination up to 2003.
在英国下斯旺西山谷克莱达赫（Clydach）的一座历史悠久的镍精炼厂周围的表层土壤（<5 厘米）中，硒（最大值 200 毫克/千克）和碲（最大值 11 毫克/千克）的含量升高。硒和碲相互关联，当将这些数据绘制成等高线图时，它们显示出以精炼厂为中心的同心图案。调查了硒和碲污染的来源。本文回顾了该地点精炼厂作业的变化，并将土壤污染与 80 多年前发生的工业污染联系起来。现有的最新空气质量数据不能排除 2003 年之前存在一些硒污染的可能性。
