TL;DR: This investigation is the first to report the bioaccumulation of triclosan in freshwater fish from India and the results indicate that this fish acts as a biomarker of exposure for tricrosan and thus shall be used to report triclassan pollution in the future.

And different meteorological factors on particulate pollution were chosen for operating variables in the model analyses.

TL;DR: In this article, the authors assess whether changes in soil properties have occurred due to direct disposal of raw OMW on soil and in evaporation ponds, and investigate the potential fate and transport of pollutants after olive oil production had ceased.

TL;DR: In this paper, the authors developed a step-by-step protocol to streamline building-specific investigations by using on-site gas chromatography/mass spectrometry (GC/MS) analysis and building pressure manipulation to determine the source of VOCs in indoor air during a 1-day field investigation.

TL;DR: In this article, a study on source apportionment of indoor dust and particulate matter (PM10) composition was conducted in a university building by using chemometrics, which investigated the potential sources of selected heavy metals and ionic species in PM10 and indoor dust.

TL;DR: Wang et al. as discussed by the authors examined residual concentrations and associated ecological risks of organochlorine pesticides (OCPs) hexa- chlorocyclohexane (HCH) and dichloro-diphenyl-trichloroethane (DDT) in water, sediment, and fish of the Songhua River in Zhaoyuan County, China.

TL;DR: In this article, seasonal and spatial variations of trihalomethanes (THMs) and haloacetic acids (HAAs) in 30 sampling points within three water distribution systems of Istanbul City, Turkey were examined.

TL;DR: In this article, a mass-dependent and mass-independent mercury isotope fractionation potentially generates unique source signatures that can be used to apportion contributions to sediment contamination, which is tractable when differences between δ202Hg of sources are larger than potential changes in isotopic signatures following the release of mercury into the environment.

TL;DR: In this article, the authors present a framework for assessing human and ecosystem risk when compost produced from agricultural wastes (AW) is applied on soil, where issues such as origin, composition and pre-treatment of AW, application rates on soils, bioavailability and mobility of contaminants present in compost, exposure routes and rates as well as determination of the fate of contaminants in soil, air, and water, are taken into consideration.

TL;DR: The spatial and seasonal distribution and concentrations of polycyclic aromatic hydrocarbons (PAHs) were investigated in core sediments of Ubeji, Ifie, and Egbokodo creeks in the Niger Delta, Nigeria.

TL;DR: In this article, the authors developed the differential UV272 absorbance (ΔUV272) related models for the prediction of the formation of trihalomethanes, HAA, and their species in raw water samples from Terkos, Buyukcekmece, and Omerli lakes under different chlorination conditions.

TL;DR: In this article, the dry deposition flux and dry deposition velocity of metallic elements attached on particulate matter were studied at the Gong Ming junior high school (Taichung Airport) and Taichung Harbor sampling sites in central Taiwan.

TL;DR: In this paper, a system combining a national soils database with a neural network was developed for prediction of source location for soil samples, which can be of crucial importance to investigating officers in a police operation or to environmental agencies attempting to locate the source of a pollutant.

TL;DR: In this paper, the authors proposed a sensitivity-based method for optimal placement of monitoring wells by incorporating two uncertainties: the source location and hydraulic conductivity, which tends to make monitoring locations as far apart from each other as possible.

TL;DR: In this paper, the authors provide an up-to-date evaluation of the occurrence and detected concentrations of methyl tertiary butyl ether (MTBE) and several other volatile organic compounds (VOCs) in public water systems, private wells, and ambient groundwater wells in New Jersey based on the best available data.

TL;DR: In this paper, a two-dimensional numerical model for evaluating the wind flow and pollutant dispersion within a street canyon was first developed using the FLUENT code, which was then validated against a wind tunnel experiment.

TL;DR: Isotopic measurements of the 34m3/s discharge from the Fall River Springs of northern California indicate recharge from 50 km upgradient in high elevation regions of Medicine Lake Volcano as discussed by the authors.

TL;DR: In this paper, the authors apply optimization and an Eulerian inversion approach to reconstruct contaminant plume time histories and identify the likely source of atmospheric contamination using data from a real test site for the first time.

TL;DR: In this paper, the molar ratios of SEMs to acid volatile sulfide (AVS) for all samples were lower than 1.0 except for the 25-to 30-cm layer of the sample collected at location YPZ, indicating that the heavy metals were currently not significantly bioavailable as a whole to benthic organisms.

TL;DR: A novel microbial source tracking (MST) method based on the detection of human and non-human markers was developed and applied to track the origin of fecal pollution in water systems and using the two approaches theorigin of fecals pollution could be successfully determined in mixed source fecally polluted waters.

TL;DR: In this article, the authors present several cases of environmental catastrophes caused by gold mining in different regions of the world (Africa, the Middle East, Eastern Europe, and South America).

TL;DR: In this paper, the current level of environmental protection, significant pieces of legislation, and five case studies regarding human rights violations are described, taking into account implications of both chemistry and law.

TL;DR: A forensic approach was used to evaluate sediments from Portao Stream, including analysis of metals, carbon (C) and nitrogen (N) stable isotopes, and C:N ratios.

TL;DR: In this paper, a review summarizes the status of thermal power plants in India and their various types of emissions that directly or indirectly produce harmful effects on the environment and human health, focusing on preventive measures used to avoid/minimize emissions.

TL;DR: In this paper, a computational model on atmospheric turbulence flow over a terrain hill shaped with rough surface was investigated under neutral atmospheric conditions, where the flow was assumed to be 2D and modeled using computational fluid dynamics (CFD) models, which were numerically solved using Reynolds-averaged Navier-Stokes equations.

TL;DR: In this paper, the authors present a method to investigate the validity of a legal claim of a sediment-impacted lake at the outfall of a mixed rural/urban watershed.

TL;DR: The United States Environmental Protection Agency/Environmental Response Team (US EPA/ERT), in collaboration with St John's College, Dr. B. R. Ambedkar University, Agra, India, is conducting a study to determine Hg vapor emission rates resulting from broken compact fluorescent lamps (CFLs) in a residential setting.

TL;DR: In this article, the main purpose of the study was to monitor ambient air particulates and particulate bound Hg (Hg[p]) compositions in different crops in the coastal zone in the Taichung, Taiwan, area at a sampling site during 2013 October to 2013 December.
