BACKGROUND Finnish and Swedish waste water systems used by the forest industry were found to be exceptionally heavily contaminated with legionellae in 2005. CASE PRESENTATION We report two cases of severe pneumonia in employees working at two separate mills in Finland in 2006. Legionella serological and urinary antigen tests were used to diagnose Legionnaires' disease in the symptomatic emplo...

A large number of human diseases are related to poor access to water and sewer systems, inadequate solid waste management and deficient storm water drainage. The goal of this study was to formulate environmental sanitation indicators and classify sanitation conditions in specific sewer basins and their respective neighborhoods. The database used contains information on the following sanitation ...

conclusions the uv/zno system has been found an effective process with 90.2% cod removal and 95.6% dye removal after 50 minutes treatment. materials and methods in this work, zno catalyst and mercury lamp (uv-c, 254 nm) have been applied for removal of the c.i. sulphur red 14 dye from aqueous environments. the influence of various parameters such as the amount of zno, initial dye concentration,...

Antioxidant depletion was evaluated in high-density polyethylene (HDPE) geomembrane (GM) coupons immersed in radioactive synthetic leachate (RSL) representative of leachate in low-level radioactive waste (LLW) disposal facilities operated by the U.S. Department of Energy’s environmental restoration programs. Depletion was assessed at four temperatures (25, 50, 70, and 90°C). Comparative tests w...
