“…The lake has experienced increasing eutrophication since the mid-1970s as a result of municipal wastewater discharge. As a typical urban lake, many researches were previously performed to study the lake pollutions (Ge et al 2014;Wang et al 2002;Yang et al 2007Yang et al , 1998. However, limited information is available on the occurrence and fate of EDCs in the lake.…”

Occurrence of five endocrine-disrupting chemicals (EDCs)-bisphenol-A (BPA), triclosan (TCS), 17a-ethinyl estradiol (EE2), benzophenone-3, and 4-methylbenzylidene camphor-were monitored in East Lake, the largest urban lake in China. Other than EE2, all selected EDCs were detected at least once in the lake water with concentrations B89.1 ng/L. EDCs were detected with greater occurrence in spring than in other seasons. In lake sediment, TCS was detected at the greatest concentration (30.9 ng g -1 ), whereas BPA and EE2 were not detected. Spatial distribution of the EDCs in the lake water and the lake sediment showed similar patterns, and greater EDC residuals were found from those sites with known wastewater input. The linear adsorption coefficients (K d ) varied from 17.9 to 1,017 L kg -1 and were related to the octanolwater partition coefficient (K ow ) values of the compounds. Photodegradation was a major process removing the EDCs from the lake water, and the presence of dissolved organic material and NO 3 -in the lake water can accelerate the photodegradation process. Degradation of the EDCs in the lake sediment was relatively slow and occurred mainly due to the microbial processes. All compounds were found more persistent under anoxic conditions than under oxic conditions.

“…Magnetic iii parameters have been widely used in environmental magnetism and some of them have been proven to be good proxies for environmental changes and contamination. Thus, magnetic proxies allow rivers to be assessed for reduced or wide extensions using the bed sediments (e.g., Scholger, 1998;Magiera et al, 2002;Jordanova et al, 2004;Desenfant et al, 2004;Chaparro et al, 2004Chaparro et al, , 2008Chaparro et al, , 2013Knab et al, 2006;Yang et al, 2007;Franke et al, 2009;Zhang et al, 2011;Sandeep et al, 2011).…”

“…According to Yang et al [3], if the magnetic susceptibility values from the pollution sources are greater than 150 × 10 −8 m 3 /kg, those values may be treated as higher magnetic susceptibility values. In the present study, higher susceptibility (> 150 × 10 −8 m 3 /kg) is observed in site numbers S 36 -S 40 , which may be due to the abundance of clay minerals along with some pollution sources (atmospheric deposition from Cuddalore town).…”

“…The spatial and temporal distribution of χ in the sediments is not only due to variable abundance of iron-bearing ferri-and antiferromagnetic minerals, but also due to the presence of diamagnetic and paramagnetic minerals such as quartz, feldspar, carbonates and clays [2]. Mineral magnetic measurements have been widely used for delineating the environmental pollution during the recent decades, because they are fast, cost-effective, non-destructive and sensitive [3].…”

“…Dust and fly ashes produced by anthropogenic activities (traffic, power plant, metallurgical settlements, and domestic waste) are rich of ferromagnetic particles. Generally, the magnetic properties of the polluted sediments are mainly determined by the anthropogenic portion and to a smaller degree by the natural (lithologic/pedogenic) minerals [3].…”

Magnetic Susceptibility and Radiological Hazardous Nature of the River Sediments - Spectroscopical Approach

Magnetic susceptibility, radioactivity and mineralogical characterization are performed on 40 sediment samples collected from the Ponnaiyar river, Tamilnadu, to establish a possible link between the enhanced concentration of anthropogenic magnetic particles, radionuclides and minerals. Higher magnetic susceptibility values (> 150 × 10 −8 m 3 /kg) are observed in last 100 km of the river. However, some elevated values are also observed in first 100 km. Frequency dependence of magnetic susceptibility is calculated to understand the magnetic grain variations which are presented and discussed. The average activity concentration of radionuclides ( 238 U, 232 Th and 40 K) falls within the typical world and Indian average values although some extreme values are determined. To assess the radiological hazard of river sediments, radiological hazard indices such as absorbed dose rate, annual effective dose equivalent, radium equivalent, hazard indices (Hex, Hin, Iγ, I and excess lifetime cancer risk) are calculated which shows below the internationally recommended values. The relative distribution of major minerals is determined by calculating extinction coefficient. Correlation analysis is carried out between the parameters obtained from radioactivity analysis and other analyses to know the existing relations. Obtained correlations are discussed and suggest that the natural radioactivity level and magnetic susceptibility of the present sediments is mainly controlled by clay content.
