“…Some studies have shown higher concentrations in some rivers [18][19][20]. However, the present results were similar to most of the reports on phthalate esters in source water in China and in other countries [2,[21][22][23][24][25][26][27][28][29][30]. The phthalate ester concentrations in drinking water in the present study were similar to those in previous studies [20,29,31,32] Table S3).…”

To evaluate the distributions and health risks of phthalate esters in the main source water and corresponding drinking water of Zhejiang Province, the concentrations of 16 phthalate esters in water samples from 19 sites were measured from samples taken in the dry season and wet season. The concentration of the total phthalate ester congeners in source water ranged from 1.07 μg/L to 7.12 μg/L in the wet season, from 0.01 μg/L to 1.58 μg/L in the dry season, from 1.18 μg/L to 15.28 μg/L from drinking water in the wet season, and from 0.16 μg/L to 1.86 μg/L from drinking water in the dry season. Of the 16 phthalate esters, dimethyl phthalate, dibutyl phthalate, di-(2-ethyl-hexyl) phthalate, di-iso-butyl phthalate, bis-2-n-butoxyethyl phthalate, and dicyclohexyl phthalate were present in the samples analyzed, dominated by di-iso-butyl phthalate and di-(2-ethyl-hexyl) phthalate. The concentrations of phthalate esters in the wet season were all relatively higher than those in the dry season, and the drinking water had higher concentrations of phthalate esters than source water. The phthalate ester congeners studied pose little health risk to nearby citizens. Environ Toxicol Chem 2015;34:2205-2212. © 2015 SETAC.

“…DEHP is added to PVC material that is used in food packaging material, medical products, plastic toys, vinyl upholstery, shower curtains, adhesives, and coatings (Fernández et al 2012). Various phthalate esters have been reported to be present in the environment, including in outdoor air, water, soil, indoor air and dust, sediment, seafood and human tissue (Fernández et al 2012; Zeng et al 2011; Santhi and Mustafa 2013). As a result, during the test procedure, reducing the DEHP background that may result from reagents, utensils and instrument systems to levels as low as possible is necessary.…”

Evaluation of the Di(2-ethylhexyl)phthalate released from polyvinyl chloride medical devices that contact blood

et al. 2014

Extraction methods that simulate those used in the clinic are recommended for obtaining extraction solutions. For polyvinyl chloride (PVC) medical devices that have contact with human blood, an alternative medium (ethanol/water mixture) is suggested as an extraction screening vehicle to evaluate the di(2-ethylhexyl)phthalate (DEHP) released. A test comparing the extraction ability between the alternative medium and whole blood from three healthy volunteers has been conducted. An experimental method is provided outlining the chemical analysis of the DEHP released from medical devices made with polyvinyl chloride (PVC). Gas chromatography-mass spectrometry (GC-MS) in the selective ion monitoring (SIM) mode was used to analyze and quantify the extracted DEHP. The linear range of the SIM method was 0.1-200 μg/mL, and the recoveries were 89.6-101.5% and 91.0-98.9% when using the ethanol/water mixture and whole blood as the extraction media, respectively. The validated method demonstrates that it is suitable for the determination of the DEHP released from PVC medical devices that have contact with blood. The results from the determination of the DEHP released will be compared with the limits derived from toxicological data for the parenteral exposure route and certain population groups, and the results will be used in the risk assessment of medical devices.

Abstract. An increased in demand from the consumer due to their perceptions on tap water quality is identified as one of the major factor on why they are mentally prepared to pay for the price of the better quality drinking water. The thought that filtered water quality including that are commercially available in the market such as mineral and bottled drinking water and from the drinking water vending machine makes they highly confident on the level of hygiene, safety and the mineral content of this type of drinking water. This study was investigated the vended water quality from the drinking water vending machine in eight locations in Parit Raja are in terms of pH, total dissolve solids (TDS), turbidity, mineral content (chromium, arsenic, cadmium, lead and nickel), total organic carbon (TOC), pH, total colony-forming units (CFU) and total coliform. All experiments were conducted in one month duration in triplicate samples for each sampling event. The results indicated the TDS and all heavy metals in eight vended water machines in Parit Raja area were found to be below the Food Act 1983, Regulation 360C (Standard for Packaged Drinking Water and Vended water, 2012) and Malaysian Drinking Water Quality, Ministry of Health 1983. No coliform was presence in any of the vended water samples. pH was found to be slightly excess the limit provided while turbidity was found to be 45 to 95 times more higher than 0.1 NTU as required by the Malaysian Food Act Regulation. The data obtained in this study would suggest the important of routine maintenance and inspection of vended water provider in order to maintain a good quality, hygienic and safety level of vended water.
