Pharmaceuticals and water supply
Prescription Drugs have been detected in water supply systems of major cities in the United States including Europe, Canada, Australia and Asia. In addition, quantities of antibiotics, steroids, antidepressants, and hormones are also present in the water supply (Doro-on, 2011). These new emerging contaminants are designed with small concentrations that can generate specific health effects. It ...

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 ...

Heat Sanitization Basics for Ultrapure and Pharmaceutical Water
Even small numbers of bacteria are a problem for critical water systems like pharmaceutical USP water, dialysis water, and ultrapure water for semiconductor manufacturing. Bacteria are often killed with UV-254, chemicals, and heat. Chemical sanitization is often undesirable or prohibited, creating a steady change-over to pure water systems that can be sanitized with heat. Most bacteria are ...

Total Organic Carbon Analysis for Purified Water and Water for Injection
Abstract In pharmaceuticals, water, specifically Purified Water (PW) and Water for Intravenous Injection (WFI), is vital for drug preparation. Producing and ensuring the cleanliness of this water entails very strict quality control and precise analytical testing methods. The United States Pharmacopeia (USP) and Japanese Pharmacopeia (JP) have promoted Total Organic Carbon (TOC) analysis as the ...

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 ...

Pharmaceuticals in water fact sheet
Recent events have led to a growing concern regarding trace pharmaceutical compounds found in drinking supplies across the United States. While pharmaceuticals have been detected in amounts far below the levels considered harmful to humans and there is no evidence demonstrating these pharmaceuticals pose a significant health risk to humans, we understand many consumers will want to protect their ...

Comparing US EPA and FDA Methods for 1,4-Dioxane in Consumer Products
Abstract 1,4-Dioxane routinely makes headlines when found in water or consumer products. A potential byproduct of the sulfation process, 1,4-dioxane is generated in the manufacture of alcohol ether sulfates and may be created in the ethoxylation process using ethylene oxide. Current methodology, including US EPA methods are normally performed on water matrices. The FDA has methods for consumer ...

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 ...

Quantitative structure property relationships for the adsorption of pharmaceuticals onto activated carbon
Isotherms were determined for the adsorption of five pharmaceutical residues, primidone, carbamazepine, ibuprofen, naproxen and diclofenac, to Calgon Filtrasorb 300 powdered activated carbon (PAC). The sorption behavior was examined in ultra-pure and wastewater effluent organic matter (EfOM) matrices, where more sorption was observed in the ultra-pure water for PAC doses greater than 10 mg/L ...

Thermoplastic Water System
The use of thermoplastic plastics in pharmaceutical and biotech water and process systems is gaining greater acceptance. Water systems are often more efficiently operated when thermoplastics such as Polyvinylidene Fluoride (PVDF) and Polypropylene (PP) are employed as compared to ones constructed of stainless steel. It is important to consider the unique properties of thermoplastics when ...

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 ...

Effect of bioconcentration and trophic transfer on realized exposure to oxazepam in two predators, the dragonfly larvae (Aeshna grandis) and the Eurasian perch (Perca fluviatilis)
Psychoactive substances are used worldwide and constitute one of the most common groups of pharmaceutical contaminants in surface waters. While these pharmaceuticals are designed to be efficiently eliminated from the human body, we know very little about their trophic‐transfer potential in aquatic wildlife. Therefore, the goal of this study was to quantify and compare uptake of an anxiolytic ...

Simplifying the Process: Automated Pharmacopoeia Testing of Purified Water and Water for Injection
Abstract The requirements for Total Organic Carbon (TOC) analysis of Water for Injection (WFI) and pharmaceutical purified water (PW) are provided for in monographs of the United States Pharmacopoeia (USP) and European Pharmacopoeia (EP). The principle behind these methods is to challenge the instrument oxidation efficiency by comparing the recovery of a standard solution (rs) and the system ...

European Pharmacopeia (EP) 2.2.44 using the Teledyne Tekmar Fusion UV/Persulfate TOC Analyzer
Abstract European Pharmacopeia (EP) Method 2.2.44 “Total Organic Carbon in Water for Pharmaceutical Use” provides method and technique guidelines to the Pharmaceutical industry. These guidelines help to qualify the TOC analysis system through a System Suitability Test that compares the recovery of a Standard Solution (rs) of 0.500 ppmC sucrose (a relatively easy compound to oxidize) ...

Food and beverage pharmaceutical pure water treatment
【Overview】 Pure water/ultrapure water treatment equipment refers to the water in which the conductive medium in the water is almost completely removed, and the non-dissociated gas, colloid and organic matter (including bacteria) are also removed to a very low degree. The electrical conductivity is generally 0.055～0.1us/cm, the resistivity (25℃)>10x106Ω•cm, and the salt content ...

Human pharmaceuticals in the marine environment: Focus on exposure and biological effects in animal species
Marine waters have been poorly investigated for the occurrence of pharmaceutical contamination. Recent data confirm that pharmaceuticals widely occur in marine and coastal environments; therefore assessment of potential risk to marine species needs further efforts. The present paper represents the first extensive review of pharmaceutical contamination in marine environments addressing the ...
