“…In fact, mercury due to its bioaccumulation property the same as other heavy metals [3], has damaging effects on vital organs such as heart, brain, liver and fatty texture and will result in different cancers. Therefore, this compound is considered as one of the most toxic metals found in the environment and a main source of pollution [4,5]. Hence, nowadays mercury ions removal from aqueous environment (water & wastewater) as one of the major challenges for hygienic management of societies has been the subject of extensive technological research [6].…”

BackgroundRemoval of mercury from aqueous environment has been highly regarded in recent years and different methods have been tested for this purpose. One of the most effective ways for mercury ions (Hg+2) removal is the use of modified nano porous compounds. Hence, in this work a new physical modification of mesoporous silica (SBA-15) with 1, 3, 5 (Trithiane) as modifier ligand and its application for the removal of Hg+2 from aqueous environment has been investigated. SBA-15 and Trithiane were synthesized and the presence of ligand in the silica framework was demonstrated by FTIR spectrum. The amounts of Hg+2 in the samples were determined by cold vapor generation high resolution continuum source atomic absorption spectroscopy. Also, the effects of pH, stirring time and weight of modified SBA-15 as three major parameters for effective adsorption of Hg+2 were studied.ResultsThe important parameter for the modification of the adsorbent was Modification ratio between ligand and adsorbent in solution which was 1.5. The results showed that the best Hg+2 removal condition was achieved at pH = 5.0, stirring time 15 min and 15.0 mg of modified adsorbent. Moreover, the maximum percentage removal of Hg+2 and the capacity of adsorbent were 85% and 10.6 mg of Hg+2/g modified SBA-15, respectively.ConclusionsTo sum up, the present investigation introduced a new modified nano porous compound as an efficient adsorbent for removal of Hg+2 from aqueous environment.

The study was conducted to investigate the effects of solid waste and industrial effluents on the water quality of Turag River. Both the upstream and downstream sampled water from the selected points were analyzed for color, odor, pH, electrical conductivity (EC), total dissolved solids (TDS), dissolved oxygen (DO), biological oxygen demand (BOD), copper (Cu), cadmium (Cd), iron (Fe), lead (Pb) and zinc (Zn) concentrations. Results of the study showed that the color of water was light to dark black and emitted noxious smell due to the industrial effluents. The upstream water was slightly alkaline with comparatively high DO content while low concentration of other parameters. The water after the solid waste and effluents received points as well as middle and downstream points was slightly alkaline with higher levels of other parameters when compared with upstream point. The minimum and maximum values of pH, EC, TDS, DO and BOD were 7.24-7.61, 425-2277 µS/cm, 239-1349 ppm, 1.22-3.66 ppm and -2.44-0.86 ppm, respectively. The continuous dumping of waste materials resulted in a marked increase in the concentration of metals in the river water varied in the order of Fe > Zn > Pb > Cu > Cd. The study concluded that the downstream water in the river was almost polluted and unsuitable for human consumption and aquaculture purposes.

The study was conducted to determine the soil pollution from the downstream area of the waste dumping site in relation to changes in soil quality as well as chemical characteristics and heavy metals concentrations in Konabari industrial area of Bangladesh, during the period from July to December 2011. Soil samples were collected from five different points at a distance of 10 m from each other. Samples were collected from two layers i.e. from surface and subsurface at a depth of 0-15 and 15-30 cm, respectively. The study concluded that the waste material produced tangible impacts on the soil quality, while the samples contained higher available sulphur (S), but lower total nitrogen (N), available phosphorus (P) and organic matter (OM) contents. The dumping of waste resulted in a marked increase in the concentration of heavy metals in soils, and the measured metals varied in the order of iron (Fe) > zinc (Zn) > lead (Pb) > copper (Cu) > cadmium (Cd). The mean concentrations of the selected heavy metals in the surface soil of the dumped site were 0.40, 1.42, 0.46, 350.38 and 0.03 ppm for Cu, Zn, Pb, Fe and Cd, respectively, while the mean concentrations of the heavy metals in the subsurface soil were 0. 39, 1.36, 0.47, 313.3 and 0.03 ppm for Cu, Zn, Pb, Fe and Cd, respectively. This could be attributed to the leachates percolated from the wastes. The metal species were found comparatively lower on the solid waste accumulation site and higher on the industrial effluents accumulation site. Such a condition could be regarded as unsafe as these heavy metals are eventually picked up by growing plants and thereby entering the food chain. So, careless disposal of the waste should be discouraged, and a waste management and treatment policy should be put in place for the waste dumping and/or disposal.
