A series of stream water, soil and fruits samples in the orchards were collected from Lianhuashan tungsten area in Guangdong Province. The concentrations of As, Cd, Pb, Zn, Cu and Ni in the samples were determined. This study targeted at the impacts of Lianhuashan wasteland on the orchards at the downstream. The results showed that the stream water was severely polluted by heavy metals, especially As and Cd, with low pH value and high electric conductivity (EC). Compared to the background orchards, the soils in the orchards at the downstream were polluted by As and Cd. The fruits in the orchards surrounding the polluted stream were seriously polluted by As and Cd. Acid waste water derived from the tailings of Lianhuashan tungsten mine entered the streams and resulted in elevated concentrations of heavy metals, lower pH values and higher EC in the stream water. The polluted streams caused soils and fruits pollution by As and Cd in the surrounding orchards.

Bioremediation was performed in situ at a former military range site to assess the performance of native bacteria in degrading hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) and 2,4-dinitrotoluene (2,4-DNT). The fate of these pollutants in soil and soil pore water was investigated as influenced by waste glycerol amendment to the soil. Following waste glycerol application, there was an accumulation of organic carbon that promoted microbial activity, converting organic carbon into acetate and propionate, which are intermediate compounds in anaerobic processes. This augmentation of anaerobic activity strongly correlated to a noticeable reduction in RDX concentrations in the amended soil. Changes in concentrations of RDX in pore water were similar to those observed in the soil suggesting that RDX leaching from the soil matrix, and treatment with waste glycerol, contributed to the enhanced removal of RDX from the water and soil. This was not the case with 2,4-DNT, which was neither found in pore water nor affected by the waste glycerol treatment. Results from saturated conditions and Synthetic Precipitation Leaching Procedure testing, to investigate the environmental fate of 2,4-DNT, indicated that 2,4-DNT found on site was relatively inert and was likely to remain in its current state on the site.
