A study on impact of municipal solid waste on groundwater in and around the dumping yard of Visakhapatnam, A.P, India

This study deals with physio-chemical characteristics of groundwater in the environs of dumping yard (GVMC), Visakhapatnam district, Andhra Pradesh. The dumping yard area is covering about 912 acres where study is carried out. Due to improper disposal of solid wastes, Hazard urbanization, industrialization leading to contamination of groundwater have been focused in this study. The improper and unscientific solid waste dumps in the unlined sewage drains drive pollutants into the groundwater regime which is an irrevocable loss and literally not possible to bring the quality of groundwater to its original state. The methodology of the project consists of field survey, collection of data. The primary data is compared with standard data (IS: 10500, 2012). 11 different groundwater samples were collected at kamalanagar colony, paradesipalem school premises, kothapalem village, kapuluppada MSW dumping yard ,thallavalsa (V), jayanthivani agraharam(V), Nedigattu(V), Chepalappada(V), Kannuru (V),Pedamusidivada(V), Tadi(V) which are around the dumping yard (Kapulauppada) during march 2016. The water samples are analyzed to identify the parameters of physical, chemical and trace metals on the basis of APHA standard methodology

Construction of 3-amino-9-ethylcarbazole scaffold for multifunctional applications: Chemosensor for copper(II) ions along with antibacterial, antioxidant and anti-inflammatory activity

This work describes the fabrication of a carbazole derivative 1 namely (E)-5-(diethylamino)-2-((9-ethyl-9H-carbazol-3-yl)imino)methyl)phenol(1) based colorimetric probe for the selective detection of copper (II) ions. The as-prepared carbazole derivative was characterized using various spectral techniques including UV–visible absorption, Emission, FT-IR, 1H NMR, 13C NMR and mass spectra. The colorimetric chemosensing potential of the synthesized carbazole derivative 1 to detect Cu2+ ions in a solution of different cations at different emission wavelengths based on photo-induced electron transfer (PET) mechanism was undertaken. In addition, the probe 1 showed significant DPPH scavenging activity. Antimicrobial and anti-inflammatory activities of the carbazole derivative 1 were also assessed. The selectivity of probe 1 towards Cu2+ ions could be exploited to reduce copper induced toxicity
