“…Volatile organic compounds (VOCs), one contaminant group of concern, could be originated from photochemical and microbial activities (Fink, 2007;Watson, 2004) and introduced to the aquatic environment by emission and combustion (Liu and Zhou, 2011). Halogenated hydrocarbons used to be thought as the most frequently detected VOCs, followed by benzene, toluene, ethylbenzene and xylene (Chary and FernandezAlba, 2012;Ma et al, 2014), thus they were known as common VOCs (Niri et al, 2008). The carbonyl compounds are also widely present in the aqueous environment, even more widely than common VOCs, which concentrations in river waters ranged from 0.04 to 513 mg/L (Chen et al, 2013;Dą browska and Nawrocki, 2013;Takeda et al, 2006).…”

Ecological risk assessment Human health risk assessment Taste and odor a b s t r a c tOwing to the growing public awareness on the safety and aesthetics in water sources, more attention has been given to the adverse effects of volatile organic compounds (VOCs) on aquatic organisms and human beings. In this study, 77 target VOCs (including 54 common VOCs, 13 carbonyl compounds, and 10 taste and odor compounds) were detected in typical drinking water sources from 5 major river basins (the Yangtze, the Huaihe, the Yellow, the Haihe and the Liaohe River basins) and their occurrences were characterized. The ecological, human health, and olfactory assessments were performed to assess the major hazards in source water. The investigation showed that there existed potential ecological risks (1.30 Â 10 RQ total s 8.99 Â 10) but little human health risks (6.84 Â 10 À7 RQ total s 4.24 Â 10 À4 ) by VOCs, while that odor problems occurred extensively. The priority contaminants in drinking water sources of China were also listed based on the present assessment criteria.

“…Extant of haloacetic acids in drinking water as carboxylic acids which a hydrogen atom replaced by halogen reported (Hebert et al, 2010). Furthermore it is mentioned disinfection by-products occurring during the disinfection process by the reaction of disinfectants (haloacetic acids, cyanogen halides, halogenated acetonitriles, chlorinated ketones and furanones) and organic matter in water (Niri et al, 2008). VOCs in group "others" are one of the main subjects in the environment (Figure 1).…”

Qualitative Evaluation of Bottled Water Stored in Polyethylene Terephtalate Based on Organic Chemical Compounds

Polyethylene terephtalate (PET) is commonly used for bottling drinking water. PET must be harmless in the sense of the migration potentially unsafe materials into its content. The quality determination of migrated organic chemicals in 15 bottled water stored in PET was performed by gas chromatography-mass spectrometry technique. Most of the organic chemical compounds including phthalate, alkyl phenol, higher alkene and organic acid were detected in the samples. However, no carcinogens and hormones were recognized in the analyzed waters. The most migrated compounds identified between 13 to 100% of bottled water. The findings of present study could be alarming for the food safety legislative establishments in Iran due to the existence of some organic compounds with adverse influence on human wellbeing. Further investigation is recommended to evaluate the risk assessment of the public health arising from the presence of these toxic contaminants in the bottled water consumed by the people. Keywords: Polyethylene terephtalate; Migration; Bottled water; Iran ResumoTereftalato de Polietileno (PET) é comumente usado para engarrafamento de água potável. PET deve ser inofensivo no sentido da migração materiais potencialmente inseguros em seu conteúdo. A determinação da qualidade de produtos químicos orgânicos que migraram em 15 garrafas de água armazenada em PET foi realizada pela técnica de cromatografia gasosa acoplada a espectrometria de massa. A maior parte dos compostos químicos orgânicos, incluindo ftalato, alquil fenol, alceno de maior peso molecular e ácido orgânico foram detectados nas amostras. No entanto, não há agentes cancerígenos e hormônios foram detectados nas águas analisadas. Os compostos migraram identificados entre 13 a 100% de água engarrafada. As conclusões do presente estudo poderia ser alarmante para os estabelecimentos legislativos de segurança alimentar no Irã devido à existência de alguns compostos orgânicos com influência negativa no bem-estar humano. Outras investigações é recomendado para avaliar a avaliação de risco da saúde pública decorrente da presença desses contaminantes tóxicos na água engarrafada consumida pelas pessoas.

“…The targeted DBPs were THMs (including iodinated species), haloacetonitriles, haloketones, halonitromethanes and some miscellaneous compounds, which, with a 30 min adsorption time and a 5 min desorption in a 200 • C injector of a GC/ECD, produced detection limits below 1.0 μg l −1 . In a more recent application, Niri et al (2008) used the same fibre in the headspace of 20 ml samples containing a 1 per cent salt solution at 35 • C and 2 min contact time for the isolation of THMs and other volatile halogenated hydrocarbons from chlorinated waters. The desorbed analytes were analysed on a GC time-offlight MS instrument whose high sensitivity, fast acquisition rates and powerful deconvolution software were instrumental in achieving the limits of detection for many of the target analytes at an order of magnitude lower than those obtained by LLE.…”

The discovery and study of disinfection by-products (DBPs) of health and regulatory concern in drinking water have often been hampered by the lack of appropriate analytical methods, but, with the new tools and expertise now available to the drinking water industry, there is an opportunity to plug a major gap in our knowledge of the nature and identity of these chemicals. The challenge is that less than half of the halogenated by-products resulting from the chlorination of drinking water have been identified, and even less is known about those produced in waters treated with ozone, chloramines or chlorine dioxide. For the DBPs that have been identified, very little or no occurrence data exist for the unregulated chemicals to document how often a particular DBP is formed and in what quantity. The elucidation of the nature and identity of these byproducts is hindered by two complicating factors. The first is the inherent aqueous solubility of many of these compounds, which renders their efficient extraction from water difficult to achieve. The second is the lack of established identity of specific potential by-products, which complicates targeted analytical approaches. This paper reviews existing and new methodologies that attempt to overcome some of these challenges.
