Detection and Management of the Pharmaceutical Pollutants from Aquatic Systems - A Mini Review
No full textPharmaceutical residues in aquatic environments are common, and studies detailing their environmental fate has been given prominence in recent years. Since some pharmaceutical residues (environmentally persistent and stable drugs) are not eliminated using conventional wastewater treatments, research on the integrated methods is needed. Photocatalysis, ozonation, electrocoagulation, oxidation, adsorption, and biological treatments (phytoremediation, bioremediation) are generally used at waste water treatment plants. The most important environmental problem facing humanity is the increasing contamination of freshwater resources globally with hundreds of recalcitrant pharma micropollutants. In recent years, it has been acknowledged that research on the prevalence and destiny of pharmaceutical residues in aquatic habitats is vital. Detection of the drugs and finding solution for their removal from contaminated sites can be achieved with the optimization of biotic (microorganisms, algae, plant) and abiotic factors (light, pH, temperature, and carbon source). This mini review gives insight on the use of enzymes for the sensing of the drugs, enzyme assisted detoxification mechanism in plants as well as microorganisms. The biotic-abiotic coupled system and in site remediation processes are also discussed.Keywords: Drugs, Enzymes, Remediation, Toxicity, Phytoremediation, Wetlan
A Bibliometric study of scholarly published literature on Bibliometrics in DJLIT during 1998-2018
No full textThe present research paper analyzed the literature published on bibliometric
research in DESIDOC Journal of Library and Information Technology during 1998-2018.
Total 86 articles found on bibliometric research during the period. Researcher selected the
literature survey and bibliometric research methodology for this study. Major findings of the
study are as follows: Only 86 (11%) articles from bibliometric research out of 780 articles. Maximum 63 articles are written by multi-authored and only 23 articles written by single author. It is good signal for collaborative research. Degree of collaboration is 0.73. Only three foreign countries author contributed. Foreign contribution should be increase. Gender wise 77% male authors and 23% female authors contributed. Female author’s contribution should be increase
Effect of pharmaceutical micropollutants (Acetaminophen and Hydroxychloroquine) and its degradative products on soil nitrate
No full textPharmaceutical drugs and its degradative products have been reported in the environmental samples like soil, sediment, and water. Based on the limit of detection very few studies have been conducted on the effect of persistent, bio accumulative and toxic drugs on the environment. Considering the impact of nitrate on soil fertility and vegetables, current study was done to assess the impact of acetaminophen, hydroxychloroquine, acetaminophen biodegradative products (hydroquinone, 4 Aminophenol), and hydroxychloroquine biodegradative products (7 Chloroquinoline 4 amine, oxalic acid) on the soil nitrogen transformation. The test compounds (10 mg/kg, 100 mg/kg, and 1000 mg/kg) were added to soil samples, whereas untreated samples served as the control. Samples of treated and control soils were processed for nitrate estimate using the Mgo-Devarda's alloy technique for nitrate-N estimation after 0, 7, 14, and 28 days of incubation. Pollutants found to have significant effect on soil nitrate. At high concentration (1000 mg/kg), soil nitrate concentration was in the extremely high region suggesting possible impact on the soil fertility and accumulation in vegetable parts. Vegetable nitrate content is considered as important quality parameter for human health. This data is helpful for determination of the negative impact of the pharmaceuticals on human diet and subsequently suggesting for the environmental monitoring of drugs before discharge into the ecosystem.

Effect of Phosphate Solubilizing Microorganisms and Phosphorus Levels on Growth Yield and Quality of Chickpea (Cicer arietinum L.) in Inceptisol
No full textA field study was conducted to know the “Effect of phosphate solubilizing microorganisms and phosphorus levels on growth, yield and quality of chickpea (Cicer arietinum L.) in inceptisol.” The experiment was laid in Factorial Randomized Block Design (FRBD) with sixteen treatments, replicated thrice during rabi season of 2019-20 at the Department Research Farm of SSAC, College of Agriculture, Latur. The treatments comprises four main (absolute control, Bacillus megaterium, Aspergillus niger and Aspergillus awamori @ 10 ml kg-1 seed treatment) and four sub treatments (0,45,60 and 75 P2O5 kg ha-1). The results indicated that, the incorporation of phosphate solubilizing microorganisms viz. Aspergillius awamori @ 10 ml kg-1 seed in combination with soil application of 75 P2O5 kg ha-1 found to be effective in improving growth and yield attributing characters viz. number of root nodules, fresh and dry weight, chlorophyll content , grain yield and straw yield as compared to Aspergillus niger and Bacillus megaterium along with 60 P2O5 kg ha-1 and over control. Further results revealed that test weight and protein percentage was significantly influenced with the seed treatment of Aspergillius awamori @ 10 ml kg-1 seed in combination with application of 75 P2O5 kg ha-1
