Presence and risk assessment of pharmaceuticals in surface water and drinking water
Trace amounts of pharmaceuticals have been detected in surface waters in the nano- to microgram per liter range, and in drinking water in the nanogram/L range. The environmental risks of pharmaceuticals in surface waters have been evaluated and generally found to be low if the wastewater is treated before release to the environment. The human health risks of trace amounts of pharmaceuticals in ...

Volatile Organic Compounds in Every Day Food
Abstract Volatile Organic Compounds (VOCs) have been analyzed in drinking water and pharmaceuticals extensively in recent years. Now, VOCs in food products have became a major interest among researchers. Utilizing an Atomx automated VOC sample prep system in conjunction with a gas chromatograph-mass spectrometer (GC/MS) will allow for the determination of VOCs in food products. The automated ...

Solving Water Vapor Challenges in Total Organic Carbon Analysis with NDIR
A review and comparison of common methods to remove moisture from a gas for analysis. What is TOC Analysis? Total Organic Carbon (TOC) analysis measures the amount of carbon present in organic compounds in a sample of water or liquid. It is a non-specific indicator of purity and quality, often detected as CO2 in fractional ppm to ppb ranges. Total organic ...

Fluxes of 13 selected pharmaceuticals in the water cycle of Stockholm, Sweden
Mass flows of 13 pharmaceutical active ingredients (APIs) found in drinking water were studied in the water cycle of Stockholm. Data were collected by analyzing samples of surface water, raw water and drinking water as well as influents, effluents and sludges from waste water treatment plants (WWTPs) in Stockholm area. A mass balance was performed, based on sold amounts of pharmaceuticals and the ...

Meeting the US Environmental Protection Agency Drinking Water Requirements with a UV/Persulfate Analyzer
Abstract The rapid and precise measurement of organic carbon in trace levels of water is of interest to the pharmaceutical, drinking water and environmental industries where regulations restrict the amount of discharge or contamination. Total Organic Carbon (TOC) analysis is considered an effective indicator of organic contamination in water. Since the US EPA set limits on Disinfection ...

Chemical pollutants in water emerge
Recent advances in contaminant identification methodologies, sampling instrumentation, and analytical chemistry have caused an explosion of knowledge about the presence of previously undetected organic micropollutants. While it doesn"t follow that the mere presence of chemical contaminants results in harm, public health experts, regulators, and others aren"t sitting idly by. Given the necessity ...

Water treatment in different manufacturing industries
Water plays a critical role in industrial processes, serving as a vital resource for manufacturing goods and maintaining machinery and supplies. However, the quality of water can differ depending on its source, whether it is from a deep well, lake, river, or municipal supply. To address water quality concerns, different treatment methods are available, with the optimal approach ...

Desk based review of current knowledge on pharmaceuticals in drinking water and estimation of potential levels
There are about 3000 pharmaceuticals registered in the UK and approximately 5000 substances listed as human pharmaceuticals were sold over the counter in the UK in 2004. In addition to the consumption of drugs for health care, there is also significant consumption of illegal drugs due to both recreational consumption and drug addiction, and for enhancement of sporting performance. The Drinking ...

Chemical and biochemical characterization and in vivo safety evaluation of pharmaceuticals in drinking water
The water constituents that are currently subject to legal control are only a small fraction of the vast number of chemical substances and microorganisms that may occur in both the environment and in water resources. The main objective of this work is to study the health impact resulting from exposure to a mixture of pharmaceuticals that have been detected in tap water at low doses. Analysis ...

Survey of human pharmaceuticals in drinking water in the Czech Republic
The first large-scale assessment of pharmaceuticals in drinking water in the Czech Republic (CR) focused on the detection of five substances. Samples were collected from public water systems supplying 5.3 million people, 50.5% of the Czech population. In the initial survey of tap water from 92 major supply zones using mostly surface water, no pharmaceutical exceeded the limit of ...

Ecopharmacovigilance – an update
Interest in this subject has been given a boost by the appearance of a new EU Directive and associated regulation revising the law on pharmacovigilance. Recital 3 in the new regulation states: “The pollution of waters and soils with pharmaceutical residues is an emerging environmental problem. Member States should consider measures to monitor and evaluate the risk of environmental effects ...

How is Reverse Osmosis Desalination Used in Tertiary Sewage Treatment Applications?
Salts and other dissolved solids can be pretty tricky to remove from wastewater streams. Standard filtration doesn’t really do anything about dissolved solids and neither does coagulation or sedimentation. They might manage to remove some, but in situations where total dissolved solids (TDS) are particularly high, those sorts of treatments do not lower TDS enough to be compliant or to reuse ...

Replacing chlorine water treatment With Alstasan Silvox
Water Treatment, a chain of process carried out to purify water with different desired end results. These include physical as well as chemical means. Visible impurities can be removed through physical means like filtration, sedimentation and decantation but problem arises for invisible pathogenic organisms which can only be removed through chemical addition. Various advanced chemical technology ...
