“…During the last decades, widespread deterioration in water quality of Wular lake has been reported due to anthropogenic influences (agricultural practices, increased exploitation of water resource, sewage runoff, agriculture, and urban sprawl) and natural processes (changes in precipitation, erosion, and weathering of crustal materials) [36,37]. Pollutants from anthropogenic activities have been increasingly produced and discharged into the Wular Lake, resulting in severe degradation of water quality, restricting the sustainable development of the local economies.…”

Multivariate techniques, discriminant analysis, and WQI were applied to analyze a water quality data set including 27 parameters at 5 sites of the Lake Wular in Kashmir Himalaya from 2011 to 2013 to investigate spatiotemporal variations and identify potential pollution sources. Spatial and temporal variations in water quality parameters were evaluated through stepwise discriminant analysis (DA). The first spatial discriminant function (DF) accounted for 76.5% of the total spatial variance, and the second DF accounted for 19.1%. The mean values of water temperature, EC, total-N, K, and silicate showed a strong contribution to discriminate the five sampling sites. The mean concentration of NO 2 -N, total-N, and sulphate showed a strong contribution to discriminate the four sampling seasons and accounted for most of the expected seasonal variations. The order of major cations and anions was Ca 2+ > Mg 2+ > Na + > K + and Cl − > SO4 2− > SiO 2 2− respectively. The results of water quality index, employing thirteen core parameters vital for drinking water purposes, showed values of 49.2, 46.5, 47.3, 40.6, and 37.1 for sites I, II, III, IV, and V, respectively. These index values reflect that the water of lake is in good condition for different purposes but increased values alarm us about future repercussions.

“…So, for all four analyzed lakes, the chemical parameters from the salinity indicator group (chlorides, sulphates, calcium, magnesium, sodium, and filtration residue dried at 105˚C) recorded very high values, characteristic of salty, sulphate and magnesium rich waters. According to the literature, this salinity is a characteristic of these lakes and may be the consequence of the intake of salts from the underground waters (springs), of the inflow of near phreatic waters or of the salt deposited from the capillaries of the rocks washing [25] [26]. The concentration of the microelements with toxic potential (heavy metals: Cd, Cr, Pb, Co) in the water samples was far below the acceptable limits of the class I quality and no significant variations were observed between the two sampling campaigns.…”

One of the most important goals of EU nature and water framework directives is to ensure healthy aquatic ecosystems by the protection of the most valuable species and habitats form the Natura 2000 network, while at the same time ensuring a balance between water/nature protection and the sustainable use of nature's natural resources. The purpose of this study was to evaluate the physico-chemical and microbiological characteristics of four Romanian salty plain lakes included in Natura 2000 Network, in order to assess the degree of organic pollution and to generate the knowledge required for the design and implementation of appropriate measures for maintaining the balance between the water protection and the sustainable use of these protected ecosystems. The water and sediment sampling was performed in two consecutive years (2015 and 2016), in September and the following standard parameters have been determined: pH, chemical oxygen consumption (COC), the degree of trophicity and salinity of the environment, metals content, microbiological indicators and microbial physiological groups involved in nutrient cycling. The pH ranged from 7.56 to 8.93, close or above the upper normal limit of 8.5, being correlated with a high salinity characteristic of chlorinated, sulphated, high sodium and magnesium content waters. Despite the similar values recorded for the physico-chemical parameters in the two consecutive years suggesting a certain degree of stability of the investigated aquatic ecosystems, the COC values indicate a high degree of hypertrophy, which could be attributed to the reduced surface area, ecological pisciculture and agriculture input. The microbiological parameters revealed the existence of both recent and chronic fecal pollution source. The high hypertrophy degree could represent a positive premise for the high productivity of the investigated ecosystems, but also an alarm signal for excessive organic pollution, with the risk of redox potential decrease which can affect the fish and other life forms. Consequently, it is necessary to identify the sources of pollution and implement the appropriate measures to minimize the negative impact of organic contamination on the status of the respective ecosystems (water quality, biotic components) in order to maintain the health of both ecosystems and the surrounding human communities, allowing at the same time a sustainable use of the local resources.

“…The quantification helps to infer climatic conditions of weathering in the provenance. The CIA index has been extensively used to study weathering conditions of the provenance and also used as an important proxy to understand the palaeoclimate (see Sharma et al, 2013;Vuba et al, 2014;Chauhan et al, 2013b;Sheikh et al, 2014).…”

“…Besides carbonates, phosphates, sulphides, sulphates, clays and oxyhydroxide of Fe, Al and Mn significantly control the contaminant and pollutant dynamics in the sediments (Brown Jr and Calas, 2011). In the last five years, studies on sediments pollution have been undertaken on lakes (Purushothaman, et al, 2012;Sheikh et al, 2014), rivers (Verma et al, 2012;Hejabi and Basavarajappa, 2013;Giri et al, 2013), aerosol (Agnihotri et al, 2015), and road dust (Mathur et al, 2011;Singh, 2011;Pathak et al, 2013). To assess the pollution level in the sediments various indices have been calculated using geochemical data of samples and reference materials, for example, enrichment factor (EF), geoaccumulation index (Igeo), pollution load index (PLI) and concentration factor (CF) (see Giri et al, 2013;Silva et al, 2014).…”

“…The geoaccumulation index indicated that the metals zinc, cobalt, and nickel are moderately polluted than other metals. Sediment samples and water samples from the Wular Lake, Kashmir Himalaya, was studied by Sheikh et al (2014) to assess the weathering and anthropogenic impact on sediment and water chemistry. CIA values of theWular Lake sediments reflected moderate weathering of the catchment area.…”

Sediment geochemistry is a powerful tool to investigate earth surface processes because sediments record geochemical signatures of their provenance, generation, transport, deposition, and environmental conditions. A significant advancement in the technology of analytical geochemistry has made geochemical analyses of sediments more rapid and precise, which together provided an impetus to the study of sediment system. As a result, high-quality research papers on sediment geochemistry have been published during the last five years from India. A foreseeable growth of research and an increase in the publication are likely in the future because of the new set-ups of state-of the-art analytical instruments for geochemical research at various research and academic institutions in India. Here we are presenting the published important work on sediment geochemistry under three categories, i.e., weathering, erosion, deposition and provenance determination; sediment geochemistry as palaeoclimate proxy; and environmental geochemistry.
