Contaminated Area

The spatial distribution of heavy metals (Fe and Mn) in the paper mill contaminated area of Jagiroad, Assam, India were investigated using statistics, geostatistics and GIS techniques. The total concentration of Fe and Mn were determined for 188 samples collected from the contaminated area. The mean concentration of Fe (7629 mg kg1) was high. The highest and the lowest standard deviation were observed in the Fe (1749) and pH (0.81), respectively. Analysis of the isotropic variogram indicated that the Fe semivariogram was well described with the Gaussian model, with the distance of spatial dependence being 1354 m, while Mn was well described with the spherical model, with the distance of spatial dependence being 833 m. The ordinary kriging estimates of Fe and Mn maps showed that high concentrations of these metals occured in the low-lying areas like bils (lakes). For both the investigated heavy metals the prediction of goodness (G) value was greater than zero. This indicates that spatial prediction is better than assuming mean of observed value as the property value for any unsampled location. Thus the geostatistical method was spatial variability of Fe and Mn.

Post Monsoon

The present paper examines the seasonal variations in groundwater quality (Pre-monsoon & Post- Monsoon) with an emphasis on paper industry effluents from the Sirpur-Kaghaznagar area. Spatial distribution of samples from 24 sites collected during pre and post-monsoon using surfer software gives an insight of important parameters such as pH, EC, TDS, BOD, COD, DO, Ca+, Mg2+, Na+, F, Cl-, NO3,- SO42- and TH to be significantly elevated beyond the acceptable and permissible levels prescribed by BIS limits. Also, the Physico-chemical analysis of paper mill effluent collected from 12 different sites revealed that parameters such as pH, EC, TDS, BOD, COD, Alkalinity, SO42-, Cu, and Fe were beyond the BIS permissible limits for effluent discharge and designated a profound negative impact on groundwater quality and lead us to conclude that the overall quality is deteriorated due to the influx of paper industry effluents.

Industrial Sewage Sludge

Biochar can be produced from many various feedstock including biomass residues such as straw, branches, sawdust and other agricultural and forestry waste. One of the alternatives is to obtain biochar from industrial sewage sludge, however, the use of such a product could be limited due to high quantities of heavy metals in the biochar as a product. Total concentration of heavy metals provides only limited information on the behavior of heavy metals, therefore, batch leaching and up-flow percolation leaching tests were applied to study the leaching of heavy metals (Cd, Pb, Cr, Ni, Zn, Cu) from (bio)char produced from two types of sewage sludge: from paper mill and leather industries. Bioanglis gali būti gaminama iš daugelio įvairių pramonės žaliavų, įskaitant biomasės liekanas, pavyzdžiui, šiaudus, šakas, pjuvenas ir kitas žemės ūkio ir miškininkystės atliekas. Viena iš alternatyvų – bioanglį gaminti iš pramonės nuotekų dumblo, tačiau tokį produktą galima naudoti ribotai dėl jame esančio didelio sunkiųjų metalų kiekio. Iš bendrosios sunkiųjų metalų koncentracijos tyrimų galima tik ribotai spręsti apie sunkiųjų metalų pasiskirstymą, todėl buvo taikomi du tyrimai: tyrimas, perkoliuojant atliekas vienakrypte srove, bei dvipakopis partijos (tyrinio) tyrimas siekiant išanalizuoti sunkiųjų metalų (Cd, Pb, Cr, Ni, Zn, Cu) išplovimą iš bioanglies, pagamintos iš dviejų rūšių nuotekų dumblo: popieriaus gamybos ir odos pramonės.

Iron Manganese

Effluents from industries contain appreciable amount of metallic cations like zinc, copper, iron, manganese, lead and cadmium. Release of heavy metal without proper treatment poses a significant threat to public health because of its persistence biomagnifications and accumulation in food chain. To reduce metal pollution problems many processes have been developed for the treatment and disposal of metal containing wastes. Certain plants have the ability to accumulate heavy metals such as Pb, Cr, Cd and Zn. At present, phytoremediation of metals may be approaching commercialization. Hence, possibility can be explored to remove heavy metal load, present even in low concentration, in waste water of paper mill effluent soil by using Croton sparsiflorus.

The present study observed the accumulation of heavy metals in Brassica juncea irrigated with paper mill effluent (PME) and control Bore well water (BWW). The soil was treated to five rates of effluents viz. 10, 25, 50, 75 and 100 ml/Kg soil. It was revealed 100% PME irrigation of soil increased Pb (+46.44%), Cr (+83.21%), Ni (+38.43%) and Cd (+78.92%). The enrichment factor (Ef) for Cr and Cd showed moderate enrichment with 10% to 75% PME irrigated soil, except Cr (5.96) which showed significant enrichment with 100% PME irrigated soil. Ef value for Pb and Ni showed deficiency to mineral enrichment with different concentrations of PME irrigated soil. The maximum accumulation of Pb (42.66±2.05 mg/kg), Cr (39.80±5.95 mg/kg), Ni (88.64±11.29 mg/kg) and Cd (5.85±0.29 mg/kg) were recorded in leaves of B. juncea, while that of Pb (43.85±3.46 mg/kg), Cr (48.59±3.81 mg/kg), Cd (6.74±1.22 mg/kg) with 100% and Ni (74.93±2.54 mg/kg) were recorded with 75% PME after 60 days in roots of the B. juncea. Ef value was found maximum for Cr (5.08) in leaves and for Pb (6.64) in roots, while the Translocation factor (Tf) was found maximum for Pb (2.45) in root of the crop irrigated with PME. The use of PME with proper dilution and with the metallic concentrations in permissible limit can be used as biofertigant for irrigation of B. juncea.
