Effect of non-aqueous drilling fluid and its synthetic base oil on soil health as indicated by its dehydrogenase activity(Environmental Earth Sciences)
(Kanchan Wakadikar, Avik Sil, Niranjan Kolekar,Vol. 64(1):,,25-28 ,Year : 2011)
|
Drilling fluids are used for drilling natural gas, oil and water wells. These spill over into the surrounding soil at the point of drilling, which may impair soil health. A laboratory investigation was carried out to determine the effect of non aqueous drilling fluid (NADF) and synthetic base oil used with it on soil health as indicated by the dehydrogenase activity. A non-sterile sandy loam soil was treated with different amounts of NADF and base oil at a rate of 800, 8,000 and 16,000 mg kg?1. Initially, reduction in dehydrogenase activity was observed, but it increased with the incubation time. On the 60th day of incubation dehydrogenase activity in untreated control was 1.04 mg TPF g?1 h?1 whereas in the soil samples treated with NADF and the base oil (16,000 mg kg?1), the activity was 1.53 mg TPF h?1 and 1.90 mg TPF h?1, respectively, which was 72 and 82% more than in untreated control. Base oil-treated soil showed more dehydrogenase activity than that observed with NADF. Both NADF and base oil stimulated the soil dehydrogenase activity.

Novel integrated photocatalytic adsorbents (IPCAs) for degradation of pharmaceuticals from water and wastewater(EPA (European photochemistry Association) Newsletter)
( D.Keane, K. Nolan, A.Morrissey, M.Oelgemöller, J.M. Tobi,,,18-21,Year : 2011)
|
The presence of pharmaceuticals and personal care products in the aquatic environment and their possible effects on living organisms has emerged as a serious environmental concern. There is an increasing need for a cost- and energy-effective clean technology for the removal and degradation of organic compounds before they find their way into ground water wells and surface waters. Photocatalysis using cheap and non-toxic TiO2 has been recently used to degrade pharmaceuticals and pesticides in water, and was found to be superior to conventional methods. However, large scale application has been hindered by problems associated with its preferential use in slurry form and the high cost of radiation of large slurry volumes. Therefore, it is proposed to combine ell-established adsorption on activated carbon with rather novel TiO2 photocatalysis. This strategy will lead to the development of TiO2-coated activated carbon materials, i.e. integrated photocatalytic adsorbents (IPCAs).

An adaptive neuro-fuzzy interface system model for traffic classification and noise predictions(International Journal of Computer Applications (0975 – 8887))
(L G Malik ,,,,Year : 2016)
|
In present study, two adaptive neuro-fuzzy models have been developed for traffic classification and noise prediction, respectively. The traffic classification model (ANFIS-TC) classifies extracted sound features of different categories of vehicles based on their acoustic signatures. The model also compute total number of vehicles passes through a particular sampling point. The results have been used for the estimation of the equivalent traffic flow (QE). The noise prediction model (ANFIS-TNP) has three inputs, namely equivalent traffic flow (QE), equivalent vehicle speed (SE) and honking. The equivalent traffic flow (QE) is the output of ANFIS-TC model, while equivalent vehicle speed (SE) and honking are computed from observed averaged speed of different categories of vehicles and number of recorded horns blow per minute. The model assumes that the distance between sound level meter and road centerline is fixed for particular sampling point. The performance of both the models has been validated by field observations. The results show that traffic classification is 100% accurate, while correlation coefficients between observed and predicted traffic noise range from 0.75 to 0.96. Both the models are validated with random samples of data, and it is observed that both the models are generalized and could be employed for traffic classification and traffic noise prediction in small urban heterogeneous traffic environment for noise pollution assessment and control.

Exploration of genetic information from dynamic microbial population for efficiency enhancement of azo dye degrading system
(Nishant Dafale
,19,,310-323,Year : 2011)
|
Dye degradation is presently an important area of scientific activity. Today, most wastewater treatment makes use of the conventional processes in the presence and action of a native microbial population. However, the potential natural microbial population and genetically engineered microorganisms (GEMs) could successfully bioaugment dye biotreatment systems to enhance efficiency. Consequently, treatment facilities are designed to maintain a high density of the desired microbial population to satisfy the bioremediation demand. Nevertheless, malefactions resulting in a decrease of activity are frequent. To better understand the function of the bacterial community, a full description of the microbial population is required. The prominent task of the microbiologist is to compare the structure, dynamics, and function of the existing microbial populations. Even though the last decade has seen a revolution in microbiology, microbial population monitoring still relies on the tools that were available at the beginning of this century. It is the goal of this review to explain the potential and importance of the newly available molecular tools for analyzing microbial populations. Molecular techniques over the last few decades have revealed an enormous reservoir of unexplained microbes. This large genetic diversity has an immense potential to be used as a resource for the development of novel biotransformations, bioremediation processes, and bioenergy generation. This paper will review bioremediation and the exploration of genetic information from microbial populations for efficiency enhancement.

Removal of Rhodamine B dye from aqueous solution by electro-Fenton process using iron-doped mesoporous silica as a heterogeneous catalyst(Chemosphere)
(R. Jinisha, R. Gandhimathi, S. T. Ramesh, P. V. Nidheesh, S. Velmathi
,200,,446-454,Year : 2018)

In the current study, Rhodamine B (RhB) dye was removed by electro-Fenton (EF) process using iron-doped SBA-15 (Fe-SBA-15; SBA: Santa Barbara Amorphous) mesoporous silica as a heterogeneous catalyst. This catalyst was prepared with the help of ferric nitrate nonahydrate as a forerunner by wet impregnation method. Various techniques of characterization such as FTIR studies, XRD, SEM and N2 adsorption-desorption isotherms were performed to confirm the presence of iron particles in the pores of the catalyst. These characterization methods were also used to examine the morphological properties and textural arrangement of the synthesized material. In the batch study of EF process, 750 mL working volume of RhB dye was taken. Anode and cathode used in the process were graphite electrodes respectively with effective area of 25 cm2 each. To maximise the process efficiency, the effect of initial pH, applied voltage, electrode spacing, the concentration of supporting electrolyte and Fe-SBA-15 dosage were investigated and optimized. The optimum conditions obtained were pH of 2, voltage of 8 V, an electrode spacing of 3 cm and Fe-SBA-15 dosage of 15 mg L-1 . At the end of 3 h electrolysis, maximum RhB removal of 97.7% and TOC removal of 35.1% were achieved for 10 mg L-1 RhB concentration. In a batch study with real wastewater, 97% of color and 39% of TOC were removed at optimum conditions. Utilization of EF heterogeneous catalyst Fe-SBA-15 is an alternative technique for the elimination of dyes from solution.

The genetic influence in fluorosis(Environmental Toxicology and Pharmacology)
(Sreemanta Pramanik, Depanwita Saha (Corresponding Author),56,,157-162 ,Year : 2017)
|
Fluorosis, caused by ingestion of excess fluoride, is endemic in at least 25 countries across the globe, China and India being the worst affected among them. Dental, skeletal and non-skeletal are the major types of fluorosis affecting millions of people in these countries. A number of genetic epidemiological studies carried out by investigators have shown the evidence for association between genetic polymorphisms in candidate genes and differences in the susceptibility pattern of different types of fluorosis among individuals living in the same community and having the same environmental exposure. These studies have pointed out that genetic variants in some candidate genes like COL1A2 (Collagen type 1 alpha 2), CTR (Calcitonin receptor gene), ESR (Estrogen receptor), COMT (Catechol-o-methyltransferase), GSTP1 (Glutathione S-transferase pi 1), MMP-2 (Matrix metallopeptidase 2), PRL (Prolactin), VDR (Vitamin D receptor) and MPO (Myeloperoxidase) could increase or decrease the risk of fluorosis among the exposed individuals in endemic areas. So, it is increasingly becoming evident that an individual's genetic background could play a major role in influencing the risk to fluorosis when other factors like specific environmental exposures including dietary patterns of fluoride intake and other nutrients remain the same. The current manuscript presents an up-to-date critical review on fluorosis, focusing mainly on the genetic association studies that have looked at the possible involvement of genetic factors in fluorosis.

Loss of Biodiversity and Conservation Strategies: An Outlook of Indian Scenario(Conservation Biology)
(Anil, M. N. V., Kumari, K. & Wate, S. R.,32,,105-114,Year : 2014)
|
This article provides a brief overview of the recent loss of biodiversity in India. By reviewing the current status of biodiversity in India, areas which need serious attention can be enumerated. There is an urgent need to monitor loss of biodiversity by analysing the situations which lead to extinction of species. It was observed in numerous case studies that major catastrophe’s occurring in develop-ing nations was attributed to loss of biodiversity. All these emphasize for a paradigm shift in the way we approach to tackle the problem. This article tries to focus on the causes which lead to loss of bio-diversity in India. This was achieved by collecting all case studies and reports from scientific jour-nals. A challenge remains, however, in using this information to provide acceptable solutions for ef-fective conservation methods. This review will outline the biodiversity loss in India by classifying data into different categories and provides an overall picture for Indian scenario. In addition, whilst not being a comprehensive review of all the biodiversity loss in India, a number of birds, fauna and flora are included in the review. Conservation strategies adopted so far in India and strategies which have been proposed are discussed at the end

Toxicity Characteristics of Drilling Mud and Its Effect on Aquatic Fish Populations (Journal of Hazardous, Toxic, and Radioactive Waste )
(Avick Sil, Kanchan Wakadikar, Sunil Kumar, S. Satheesh Babu, S. P. M. Sivagami, Patrick Hettiaratchi,Vol.16(1),,,Year : 2010)
|
oxicity tests are important for assessing the effects of complex chemical mixtures, such as waste drilling mud, on aquatic ecosystems. When waste drilling mud is released into the marine environment, strong ocean currents perhaps separate the drilling mud into a solid phase (SP) and a suspended particulate phase (SPP). A comprehensive assessment of drilling mud and base oil was carried out in the laboratory for acute fish toxicity (freshwater fish, marine fish, and benthic organisms) and biodegradability. The results presented in this paper indicate that the LC50LC50 96 h for fresh water, marine and benthic organisms was in the order of base oil >SP>SSP>SP>SSP. The 28-day biodegradability of base oil was also more than that of drilling mud. The results also showed that nonaqueous drilling fluids (NADFs) are readily biodegradable. The Spearmen results clearly showed the effects on fish populations from the discharge of drilling mud into aquatic systems. The results showed that the use of NADFs instead of water-based fluids (WBFs) would have lesser adverse impact on the environment.

Change in drinking water quality from source to point of-use and storage: a case study from Guwahati, India( Environment Monitoring and Assessment)
(,,, 5343-5361,Year : 2012)
|
|
To ascertain the quality of drinking water being supplied and maintained at Guwahati, the study was conducted on the status of water supply in city through surveillance of drinking water quality for consecutive 7 days at various treatment stages, distribution network and consumer ends. The performance of five water treatment plants (WTPs), viz. Panbazar WTP, Satpukhuri WTP, Kamakhya WTP, PHED WTP and Hegrabari WTP were assessed for summer, piost-post-monsoon and winter seasons. No significant change in raw water quality was observed on day-to-day basis. Residual chlorine was found in the range of nil to 0.2 mg/L in the treated water. During post-monsoon, winter, and summer seasons the thermotolerent TC and FC counts ranged between Nil to 168 CFU/100 ml and Nil to 84 CFU/100 ml; Nil to 3356 CFU/100 ml and Nil to 152 CFU/100 ml; and Nil to 960 CFU/100 ml and Nil to 108 CFU/100 ml respectively. There was variation in bacterial counts among the different service reservoirs and consumer ends, which may be attributed to the general management practices for maintenance of service reservoirs and the possibility of enroute contamination. Evaluation of the raw water quality indicate that the water is suitable for drinking after conventional treatment followed by disinfection. The finished water quality meets the level of standards described as per Bureau of Indian Standard specifications (BIS:10500 1991) for potability in terms of its physico-chemical characteristics.
