Tailings are mine wastes in the form of slurries stacked in mine sites abandoned after the exhaustion of ores. There are approximately 5000 abandoned mine sites in Korea, and tailings have become a serious environmental problem. Long-term environmental exposure of tailings can cause release of acidic and high concentrations of sulfate- and metal-contaminated water (acid mine drainage, AMD). Org...

Effects of Low-Level Chronic Radiation on Plant Nuclear Parameters as Related to Successional Patterns by Eric A. Rechel, Master of Science Utah State University, 1977 Major Professor: Dr. W. F. Campbell Department: Plant Science vi A major i ss ue facing nuclear power stations is how to effectively deal with radioactive waste. This waste, as it comes from a reactor, is emitting large quantitie...

Mining tailings represent a generating source of rich heavy metal material with a potential danger the public health and the environment, since these metals, under certain conditions, can leach and contaminate aqueous systems that serve like supplying potable water sources. The strategy for this work is based on the observation, experimentation and the simulation that can be obtained by binding...

The seepage field of tailings dam is closely related to the safety state. Real-time evaluation based on monitoring data great significance ensure safe operation pond. premise accurately evaluating status reliability data, and it necessary identify anomalies data. Because complex influence factors dam, traditional anomaly identification method regression model fails due its low fitting accuracy....

Archaeal 16S rRNA gene compositions and environmental factors of four distinct solfataric acidic hot springs in Kirishima, Japan were compared. The four ponds were selected by differences of temperature and total dissolved elemental concentration as follows: (1) Pond-A: 93°C and 1679 mg L(-1), (2) Pond-B: 66°C and 2248 mg L(-1), (3) Pond-C: 88°C and 198 mg L(-1), and (4) Pond-D: 67°C and 340 mg...

phytoremediation is a technology that uses plants for the remediation of the contaminated soils, sediments, tailings, and groundwaters. in this work, the ability of trifoliumalexanderium for the phytoremediation of the tailings soil in the anjir-tange coal washing plant was investigated. for this purpose, trifolium sp. was cultivated in three soils consisting of the tailings dam, an agricultura...

1. Haemoglobin production was measured for two populations of Daphnia putex, one from a temporary pond (GR Pond) and one from a permanent pond (Rash Pond). Surface water in Rash Pond remains high in oxygen, while by late summer very Uttle oxygen remains in GR Pond. Haemoglobin synthesis was induced in the laboratory by artificial oxygen deficiency. 2. Reproductive state influenced the level of ...
