“…Jenkins and Frazier (2010) have documented threats to swamp environments in the Western and Southern Coalfields regions of the Sydney Basin associated with underground longwall mining. Mining-introduced heavy metal contaminations also impose ecological risk in wetlands (Vaezi et al 2015). Concern has been raised regarding subsidence effects on wetlands, slope changes, contamination of groundwater, and soil moisture fluctuations (Booth 2006;Jenkins and Frazier 2010).…”

Thirlmere Lakes is a group of five freshwater wetlands in the southwest fringe of Sydney, Australia, that is subject to cyclic wetting and drying. The lakes are surrounded by activities that have led to increasing pressure on the local surface and groundwater supply including farming and mining. The mine has been operating for more than 30 years, and in recent times, there has been speculation that the surface subsidence and underground pumping may have some impact on surface water and groundwater hydrology. A study was undertaken using satellite imagery to examine the relation between water area changes and rainfall variability. The study utilised Landsat time-series data during the period 1982-2014 to calculate changes in the lake water area (LA), through the normalised difference water index (NDWI) threshold. High classification accuracy was achieved using NDWI against high-resolution data that are available for the years 2008 (88.4 %), 2010 (92.8 %), and 2013 (96.9 %). The LA measurement was correlated against 11 historic observations that occurred in 2009, 2010, and 2011 during drier wetland conditions. Correlation analysis of the LA with the residual rainfall mass spread across the past 30 years has found that rainfall variability is a major dominant factor associated with the wetland changes. The underground mining operations, if verified by independent investigations, probably play a minor or negligible contributor to variations in total wetland area during the study period.This study has demonstrated that remote sensing is a technique that can be used to augment limited historic data.

Background The environment is always subjected to exposure from different natural and anthropogenic sources of trace elements. The excessive intake of these trace elements may become toxic and cause health disorders to the people when the concentration exceeds certain threshold limits. The measurement of trace elements concentration in general and toxic trace elements concentration in particular is important for the assessment and prediction of risk to the environment and public. Distribution of trace elements in various environmental matrices depends on the nature of the element itself and the site-specific characteristics such as type of the matrices and its physicochemical parameters. In view of these aspects, an attempt is made to assess the concentration of trace elements and pollution indices in the sediment samples collected from the coastal belt of Kerala and possible conclusions were drawn. Results The results of pollution indices clearly indicate the moderate level of trace elements contamination in the coastal belts of Kerala. Significant correlations were observed between the concentration of trace elements and physicochemical parameters of the sediments. Conclusion Most of the trace elements enrichment in the coastal belt is due the crustal materials or natural weathering process and atmospheric deposition. The investigation revealed the sources of most of the elements present in the coastal belt of Kerala are lithogenic such as weathering and atmospheric deposition.

Soil samples in Moryayla village located 156 km northeast of Erzurum and Cu mineralization area around it were collected randomly. In these samples, 20 samples were taken in order to investigate the metals found and the pollution limits of these metals and the sources that cause this pollution. The geochemical analyzes (Cd, Cr, Cu, Ni, Pb, Zn and Fe) of the collected soil samples were made and evaluated with the pollution parameters. In the calculation of these parameters, enrichment factor (EF); geoaccumulation index (Igeo); contamination factor (CF) and pollution load indices (PLI) were used by using average shale values and crust values. Statistically obtained Cu values were calculated as minimum 25.2 ppm, maximum 79.7 ppm and average 45.2. Among the statistically analyzed elements; A high positive correlation was observed between Cd and Pb and Zn, Cr with Ni and Pb and Zn (p
