The present study developed a multistandard color chart for detecting uranium (U) by arsenazo III using digital cameras with color tool measurements and compared it with conventional methods. The color chart is red to dark red as monochromatic for cameras. The detection limit is 5 ng/mL using a preconcentration factor of 100, which is well below WH...

Lab-on-a-paper-based devices are promising alternatives to the existing arduous techniques for point-of-need monitoring. The present work reports an instant and facile method to produce a microfluidic paper-based analytical device (µPAD). The fabricated µPAD has been used to detect hypochlorite (OCl −) by incorporating newly synthesized chromo-fluo...

The analysis of hexavalent chromium (Cr (VI)) is an important water quality monitoring for public health safe consumption. Many high- end instruments were accessible to detect total Cr precisely at parts per trillion. Because of high upkeep of instruments, important to recognise on field examination and adjusting to low-volume (green chemistry...

Dichlorvos (DDVP) analysis using visible spectrophotometer, gas chromatography-mass spectrometry and liquid chromatography mass spectrometry has been studied extensively. The major drawback of all the method is requirement of standardisation, expensive and maintenance nature of instrument involvement. Since, many governments has banned the use of D...

Southern Tamil Nadu has placer deposits, which is rich in minerals like zircon, garnet, monazite and rutile containing with radionuclides of U, Th and their decayed products. The present study is to identify the high background radiation areas in the regions of South west–east coast of Tamil Nadu. The ground radiometric survey was conducted in diff...

In this article, we report the first the use of inductively coupled plasma tandem mass spectrometry (ICP-MS/MS, Agilent 8800) as a rapid alternative for the time-consuming measurement of ²¹⁰Pb in drinking water by radiometric approaches. After thorough cross-optimization of the tandem mass spectrometer to maximize signal-to-noise ratio at m/z 210,...

Objective: The present study was conducted to investigate the qualitative and quantitative screening of phytochemicals, and characterization by HPTLC finger print analysis, HPLC and GC MS substantiation for the presence of scopoletin and rutin in methanolic leaf extracted of Morinda tinctoria Roxb. (MEMT). Methods: The Qualitative and Quantitative...

Remediation of contaminated sites using specific plant or plant groups may offer a cheap, renewable and promising technique to minimize the long-term ecological adverse impact of the waste disposal. The major components of process waste of uranium industry are uranium series radionuclides, heavy metals inherently present in the ore, chemical additi...

The distribution of naturally occurring radionuclide Polonium-210 (210Po) activity in dietary source of Kalpakkam, Nuclear Power Plant, Tamil Nadu and its nearby region was studied. The 210Po was analyzed in the food materials consumed by the male and female individuals (he/she) living in the study area of Kalpakkam (nuclear power plant) was done b...

Purpose: To study the distribution of Polonium (210Po) activity in dietary sources in high background radiation zone Puttetti of southern Tamil Nadu. Materials and methods: 210Po was analyzed in the food materials consumed by the male and female individual representatives (he/she) living in the high background areas by 24-hr Duplicate Diet Study (D...

Introduction: There are several methods used for analyzing the uranium in dietary samples such as neutron activation analysis (NAA), alpha spectrometric determination, inductively coupled plasma mass spectrometry (ICP-MS) and fluriometry (Forte et al. 2001). For activity determination, NAA and alpha spectrometry are the best to determine the isotop...

The aim of this study was to assess the levels of various trace metals present in water and sediment of Fresh water Aquatic Ecosystem during the post monsoon season. The study was extended to identify the trace metal contamination in the water and sediment samples collected along the shores of Lambapur and Peddagattu the tribal villages in India us...

A study was conducted to estimate the thorium concentration in locally grown vegetables in high background radiation area (HBRA) of southern coastal regions of India. Locally grown vegetables were collected from HBRA of southern coastal regions of India. Thorium concentration was quantified using instrumental neutron activation analysis. The sample...

The occurrence of micronuclei (MN) and other erythrocytic nuclear abnormalities (ENA) were used to assess the genotoxic potential of lead in vivo by comet assay and micronuclei assay in Catla catla (2n = 20), as a test model. Prior acclimatized fishes were divided into four groups. Group I served as positive control, and the other three as exposed...

Radium is a natural decay product of Uranium series (226Ra) and Thorium series (228Ra) emits alpha radiation. The south coast of Tamil Nadu has rich source of monazite, a major constituent of thorium and other rare earth elements like uranium, cerium, lanthanum in large quantities. The activity concentration of 226Ra & 228Ra in food stuffs and the...

210Po is the decay product of natural radionuclide of 238Useries. The presence of a radionuclide migrates from soil > plant> food and ingested by the humans residing in the areas of syentite rocks nearby the High Background Radiation Area’s (HBRA). The food samples were studied by Market Basket Study (MBS). The average concentration of 210Po in foo...

South Coast of Tamil Nadu has rich source of monazite, a major constituent of thorium and other rare earth elements and referred as high background radiation areas (HBRA’s). People living in HBRA’s region are expected to receive significant amount of radiation via ingestion of food material grown in HBRA’s and accumulated in the human organs causin...

Manavalakurichi is located in the south west coast of Tamil Nadu. This place is said to be one of the High Background Radiation Areas (HBRA’s) in the world. Background radiation is due to the presence of Monazite (Thorium ore) in the coastal zone of Manavalakurichi sector. 232Th, 238U & 40K are the main naturally occurring radionuclides and along w...

Background: High background radiation areas in Manvalakurichi (Tamilnadu) contain more amounts of monazite, a major constituent of thorium and other rare earth elements. People living in HBRA’s region are expected to receive significant amount of radionuclides through ingestion of food material grown in HBRA’s and the radionuclides were accumulated...

Background: Radon is an inert, radioactive gas that decays to produce alpha particle emitting progenies of great concern to the environment. Epidemiological evidences such as cohort studies of underground miners with relatively high level of radon exposure, case control studies etc., have shown that exposure to high levels of radon leads to lung ca...

Synthetic Chemical insecticides have many benefits, but they also posses some hazards for those alternatice methods used. One such alternative is the use of microbial insecticide especially Bacillus thuringiensis. The organisms used are essentially non-toxic and non-pathogenic to wild life, humans and other organisms. The toxic action of microbial...
