“…These data shows the mercury emission from coal combustion and non-coal combustion in Zhejiang, Jiangsu provinces and Shanghai had been increasing faster than all China's average rate in recent years and at the same time most of the Hg p and Hg 2 + would probably be transported into the water and soil near these areas by atmospheric deposition as reported by Alligui (2010). This may be the main reason of the gradually mercury increasing in the sediment of the Dianshan Lake.…”

The mercury in sediment cores from Dianshan Lake, Shanghai is studied in this study and it indicates that the mercury level changing from 52.78-145.66 Î¼g kg^-1 in sediment can be obviously divided into three sections responding to the development of economy of Shanghai. Mercury decreases with depth in 0-11 cm underground, which is corresponding to the depositing period after 1980; and it is in less change with depth in 11-16 cm, which is corresponding to the period of middle 1960s-1980s. Below 16 cm Hg is decreasing with depth more obviously, which is corresponding to the period from the establishment of the Peopleâs Republic of China to the beginning of the Culture Revolution in 1970s. These indicate that the pollutants transported to the Dianshan Lake before 1980s are less than that after 1980 and in the period of 1970s Hg transportation to the Dianshan Lake is relatively decreasing with time. This mercury-increasing trend in the Dianshan Lake is consistent with the mercury release from coal combustion and non-coal sources in Yangtze Delta (mainly including Jiangsu, Zhejiang provinces and Shanghai) and is also a reflection of the economy development in Shanghai; It is, however, not associated that close to the protection of the lake. These facts indicate that the atmospheric deposition is probably the main source of mercury in the Dianshan Lake and the mercury level would probably be evidently increasing in this lake in certain period of time in the future even though protection efforts are now in process in Shanghai.

“…The resultant acidification of the water from sulfur oxidation, coupled with oxidation itself, can lead to both chemical and microbial release of other pollutants and so mining areas can contain relatively high levels of toxic substances, such as cyanide, sulfate and potentially toxic heavy metals (i.e., Pb, Zn, Cu, Cd, Fe, Mn and Al), which can pose adverse long-term impacts on animals, human health and ecosystem degradation (Ardejani et al, 2010;Liang-qi et al, 2010;Perez-Lopez et al, 2007;Silvia and Zanetti, 2009;Unruh et al, 2009). Under an AMD situation, the release of such toxic substances can severely pollute the soil, surface and ground water systems (Alligui and Boutaleb, 2010;Mossad and Aral, 2010;Oprea et al, 2010;Ouangrawa et al, 2010;Rani and Chen, 2010). Although this process occurs naturally, mining industries may significantly accelerate AMD through disturbing the sulfide mineral and promoting their expose to water and oxygen.…”

Problem statement: Acid mine drainage from waste rocks, tailings and other mine components, is one of the most important environmental concerns at mining sites. To attempt to determine the balance between the acid and neutralization potentials of the material and evaluate the possible acid-forming potential of mine waste, many static prediction tests have been developed to evaluate the acid-forming potentials of samples in recent years. Approach: This study attempts to highlight and summarize their essential issues and collates the mining projects that have used such static tests. Results: The advantages and disadvantages of each technique are compared to formulate and present guidelines for the appropriate selection and application of these tests. According to many studies, although several test methods have been modified in recent years, the ABA, NAG and paste pH methods are the most commonly static tests reported for initially indicating the acid-generating and neutralizing potential of samples. Conclusion/Recommendations: To provide confident acidforming predictions and consequently, the best waste management plans, at least several different techniques needs to be applied together in order to classify the acid generating potential of a sample more reliably.

Acid mine drainage (AMD) gives rise to several problems in sulfide-bearing mineral deposits whether in an ore body or in the mining wastes and tailings. Hence, several methods and parameters have been proposed to evaluate the acid-producing and acid-neutralizing potential of a material. This research compares common static methods for evaluation of acid-production potential of mining wastes in the Muteh gold mines by using 62 samples taken from six waste dumps around Senjedeh and Chah-Khatoun mines. According to a detailed mineralogical study, the waste materials are composed of mica-schist and quartz veins with a high amount of pyrite and are supposed to be susceptible to acid production, and upon a rainfall, they release acid drainage. All parameters introduced in different methods were calculated and compared in this research in order to predict the acid-generating and neutralization potential, including APP, NNP, MPA, NPR, and NAGpH. Based on the analytical results and calculation of different parameters, all methods are in a general consensus that DWS-02 and DWS-03 waste dumps are acid-forming which is clearly attributed to high content of pyrite in samples. DWS-04 is considered as non-acid forming in all methods except method 8 which is uncertain about its acid-forming potential and method 7 which considers a low potential for it. DWC-01 is acid-forming based on all methods except 8, 9, 10, and 11 which are also uncertain about its potential. The methods used are not reached to a compromise on DWS-01 and DWC-02 waste dumps. It is supposed that method 7 gives the conservationist results in all cases. Method 8 is unable to decide on some cases. It is recommended to use and rely on results provided by methods 1, 2, 3, and 12 for taking decisions for further studies. Therefore, according to the static tests used, the aforementioned criteria in selected methods can be used with much confidence as a rule of thumb estimation.
