Prosenjit Mitra, Prosenjit Pramanick, Pardis Fazli and Abhijit Mitra; JECET; March 2018- May 2018; Sec. A; Vol.7. No.2, 162-175.;[DOI: 10.24214/jecet.A.7.2.16275.]


A study was undertaken during May 2017 to monitor the impact of tidal actions on the hydrological parameters of the Hooghly estuary. The water quality reflects the impact of Bay of Bengal (sea) water almost on all the variables as revealed from the significant difference of parameter values in high and low tides (except surface water temperature and K). The 12 selected stations from the upstream to downstream regions exhibited uniformity with respect to surface water temperature. Significant spatial variations (at 5% level of significance) were observed with respect to parameters like surface water salinity, pH, alkalinity, DO, BOD, COD, NO3, PO4, SiO3, extinction coefficient, SO4, Na, K, Cl and total N. Along with tidal influences, the anthropogenic factors contributed by the adjacent cities and towns exert a regulatory influence on parameters like BOD, COD, NO3, PO4, extinction coefficient, SO4 and total N.

Tejas U. Padghan, Ratnadeep R. Deshmukh, Jaypalsing N. Kayte., Pooja V. Janse.;JECET; March 2018- May 2018; Sec. A; Vol.7. No.2, 156-161.;[DOI: 10.24214/jecet.A.7.2.15661.]


Soil salinization becomes universal problems mostly in arid and semiarid irrigated agriculture areas. Soil salinity is a process which affects the quality of soil and reduces crop yields and agriculture production. The soil salt content adversely affects the soil physical property including soil water content. The Visible and Near-Infrared Reflectance Spectroscopy provides improved estimation of soil salinity as fast approach to the characterization of soil salt content with spectral resolution of 350-2500 nm. The Partial Least Square Regression Method (PLSR) is frequently used to determine Soil Salt Content (SSC) obtains from the spectral data. This reviews on the estimation of salt content (SC) using Vis-NIR spectroscopy.

Dr. Hemlata Raikwar, Dr. Anita Chouwbay;JECET; March 2018- May 2018; Sec. A; Vol.7. No.2, 151-155.;[DOI: 10.24214/jecet.A.7.2.15155]


There are about 6.5 billion people living on planet earth. Worldwide paper consumption in this century has increased 4 times faster than pollution. Paper and worldwide will reach 400 million tonnes is 2011 and 640 million tonnes in 2020 with world population of 8000 million people and per capita consumption of paper and paperboard of 80 kg. There are about 500 Kraft mills and many thousands of other types of pulp and paper mills in the world. The Indian paper industry is among the top 15 global players today, with an output of more than six millions tonnes annually with an estimated turnover of Rs. 150,000 million. Project demand of 14 million tonnes.

Assessment of Industrial Effluents and Its Impact on Ground Water Quality in North of Musi River, Hyderabad, Telangana State - India

K. Srujan, Venkateshwarlu.Ch, Ramu Tharla, V.Vasu, V.Saidulu2, M. Ramu; JECET; December 2017- February 2018; Sec. A; Vol.7. No.1, 111-120.; [DOI: 10.24214/jecet.A.7.1.11120]


Due to rapid industrialization and overexploitation of the groundwater resources, there is a drastic change taking place in the Hyderabad urban environment. The present study area is categorized into 1.Tannaries of Bholakpur area, 2. Pharmaceutical industries at VST Vidyasagar, 3. Domestic an industrial sewage in Musi River at Nallachervu, Pirzadiguda, Uppal area of Hyderabad, Andhra Pradesh, India. The possible quality of the heavy metals major and trace elements in the hydrological system have been identified and quantified in the present study. Depending on the environmental parameters, the trace metals and associated elements may form complexes and precipitate or become concentrated at several places. In the present study is an attempt made to evaluate the changes in the water quality of the Hyderabad urban environment. All trace elements, which include As, Se, B, V, Fe, Co, Pb, Cu, Zn, Cd, Mn, Ni, Mo, and Ba, and Na, Mg, Si, Ca, Al, were analyzed using the highly sensitive inductively coupled plasma-mass spectrometer (ICP-MS). For most of the elements, the detection limits are around 1 ppb. Analytical data were processed with various computer programs for statistical evaluation. The impacts of natural and anthropogenic sources on the elemental concentration and the total area affected by each element have been deciphered using these graphs. The range and average concentrations of some of the trace elements of environmental concern in the groundwater. Most of the trace elements show high concentrations (several orders of magnitude) in the groundwater of Hyderabad in comparison to global average standards. Especially salts like Na, Ca, Mg, Se, are at peak levels and add turbidity to water and make it worst.

Soil Organic Carbon (SOC) regulation by anthropogenic activities and natural factors

Pritam Mukherjee, Madhumita Roy and Abhijit Mitra; JECET; December 2017- February 2018; Sec. A; Vol.7. No.1, 103-110.; [DOI: 10.24214/jecet.A.7.1.10310]


The present study has illustrated the estimation of the Soil Organic Carbon (SOC) distribution keeping in view the variation of environment. Hence two significantly contrasting environments were selected to evaluate the role of anthropogenic/natural factors on the SOC budget. The regions selected as experimental beds for the present study are highly urbanized city of Kolkata and natural mangrove ecosystem of Sundarbans. 6 stations in each of these two regions were selected during January 2018. We observed relatively higher value of SOC at Kolkata (mean value = 1.95%) compared to mangrove dominated Indian Sundarbans (mean value = 1.37%). The relatively higher values in the city soil may be due to the impact of domestic and municipal waste generation and dumping by the heavily crowded population of the city. The lower value of SOC in Sundarbans may be attributed to the tidal washing of the top soil at regular intervals of time. Erosion of embankments is also a cause of low SOC value in Sundarban region.
