TL;DR: Aquatic humic solutes were isolated from lake water by two different methods: non-ionic sorbing solid (XAD technique) and weakly basic anion exchanger (DEAE cellulose) as mentioned in this paper.

TL;DR: Ellenson et al. as discussed by the authors analyzed residential air, household dust, and soil pollutant concentration data for exposure assessments, finding that indoor air concentrations of many species were higher than outdoor air concentrations and were attributed to household activities, ventilation of residences, and track-in of dislodged soils.

TL;DR: The quantity and quality of the microbial population seem to be reasonable in this observation and will serve as references for future studies.

TL;DR: An investigation into the types and numbers of airborne microorganisms was carried out in three varying types of residential houses in Al-Ain City, UAE, to establish future reference standards and to determine if they have affected, and to what degree they may affect, human health as discussed by the authors.

TL;DR: In this paper, the authors evaluated different frequency weightings for prediction of rated annoyance and found that dB(A) was inferior to any other frequency-weighted sound level as a predictor of annoyance.

TL;DR: In this paper, personal monitoring over a 24-hour period was performed using over 190 subjects divided into two distinct groups, one for housewives and one for office workers, and the highest median levels of RSP, ETS particles, and nicotine were measured for subjects working in smoking workplaces.

TL;DR: In this paper, two facultative anaerobic bacterial cultures, a mixed one (BMM) and a pure one (DTB), were isolated through enrichment on yeast extract containing mineral media inoculated with textile dyes' discharge effluent.

TL;DR: In this paper, it is shown that structural alterations take place in the block of dissolved organic matter, in addition to the removal of certain impurities, during isolation of aquatic humic substances with the XAD technique.

TL;DR: Congener physical and chemical parameters, different degradation rates, feeding habits, and mobility of the analysed aquatic organisms, metabolism, and excretion mechanisms, are to be considered to explain the distinctive PCB patterns of different samples.

TL;DR: The reaction between iron(II) hydroxide and solutions containing oxoselenium anions results in a dramatic reduction in the concentrations of dissolved selenate and/or selenite as discussed by the authors.

TL;DR: In this paper, a system for reducing biological organisms in a liquid effluent to non-viable organic molecules that includes: a stunning chamber that applies a voltage potential across biological organisms to break cell membranes and disable the defense mechanisms of vital organisms to ultraviolet radiation; a cavitation chamber to physically destroy any remaining membranes of biologicals in the effluent that may play host to vital organisms or allow such to hide therein, the action of the stunning and cavitation chambers releasing interferons; and a molecularly implanted stimulated emitter (MISE) chamber in which high levels of ultraviolet

TL;DR: The concentrations of total organic carbon (TOC), total petroleum hydrocarbons (TPH), and petroleum-related heavy metals were determined in sediment samples collected from eight stations along the coastal area in Kuwait.

TL;DR: In this paper, the concentrations and size distributions of organic carbon (OC), elemental carbon (EC), and polycyclic aromatic hydrocarbons (PAHs) were measured with a PS-1 sampler, NRI (Noll Rotary Impactor), and MOUDIs (Micro-orifice Uniform Deposit Impactor) in the ambient air of the traffic intersection and rural site in the Ping Tung area of Southern Taiwan, from September 1994 to December 1995.

TL;DR: In this article, the concentration of Cd, Pb, Zn, Cu, Mn, and Fe in soft tissue and byssal threads of Perna perna from the Gulf of Aden, Yemen, were determined by atomic absorption spectrophotometric (AAS) method.
