Screening of pharmaceuticals and hormones at the regional scale, in surface and groundwaters intended to human consumption 总被引:6,自引:0,他引:6
As part of a regional screening to evaluate the risk, for the health of populations, to certain classes of emerging substances, several families of pharmaceuticals and hormones were looked for in waters intended to drinking. Thus, 52 substances were investigated in 71 surface waters and 70 groundwaters. Results indicate that no water was free of pollutants, regardless of its origin (surface or groundwater) and the season of collect. The pharmaceuticals most frequently detected and with the highest concentration levels were salicylic acid, carbamazepine and acetaminophen. Among hormones, testosterone, androstenedione and progesterone were detected in almost all the samples. Globally the groundwaters were less contaminated than surface waters in regards pharmaceuticals frequencies and levels. On the other side, androgens and progestagens were present with comparable frequencies and levels in both compartments. The risk linked to the presence of these substances on human health is discussed. 相似文献

The levels of a wide variety of pharmaceuticals and hormones, in source and potable-water supplies of French drinking water
treatment plants, were assessed. In surface waters, 27 of the 51 target compounds were determined at least once. Paracetamol,
salicylic acid and carbamazepine were quantified in more than 80% of samples. The highest concentration of 71 ng/L was observed
for paracetamol. Twelve other substances were widely found in the surface waters studied, contaminating between 33 and 80%
of the samples. These compounds include analgesics, psychotropic drugs, antibiotics and beta-blockers consistent with the
French consumption, as well as natural hormones (oestrone, progesterone and androgens) and synthetic progestatives. In drinking
water supplies, 25 compounds were also present, salicylic acid being the most frequently detected. Carbamazepine and the β-blocker
atenolol found at lower levels (maximum 2 ng/L), are also present in more than 30% of the contaminated drinking waters. The
pharmaceuticals exhibit different reactivity towards the treatments, while progestagens and androgens seem resistant to most
of them. The effectiveness of the treatments is discussed, as well as the consequences of the presence of all these compounds
on human health. This is the first time that such a long list of compounds (51) is proposed to assessment, and consequently
this study provides the first data on pharmaceuticals and steroids occurrences in French drinking waters and represents a
basis for the assessment of risks for humans. Moreover, at the international level, this is the first time that so many substances
are quantified in drinking water, due to the very low detection limits, especially in the case of the hormones. 相似文献

The photocatalytic degradation of a sulfonylurea herbicide, cinosulfuron, has been studied in TiO2 aqueous suspensions. A first order kinetic law was found. The influence of the initial concentration of cinosulfuron and
of the initial radiant flux on the kinetics were evaluated. The identification of the intermediate products was based on high
performance liquid chromatography coupled with mass spectrometry analyses (HPLC-MS). The mineralization of cinosulfuron was
traced using ion chromatography and total organic carbon (TOC) measurements. These results indicate that the photocatalytic
degradation of cinosulfuron leads to CO2, NO3
− and SO4
2− as final products, and in addition cyanuric acid (C3H3O3N3), confirming previous results on triazinic ring-containing compounds.

Numerous chemical products are dispersed into the environment, and the consequences can be sometimes harmful to humans and ecosystems. Pharmaceutical compounds and hormone steroids are among these substances that concern the scientific community. Currently, little data are available on the presence and fate of these compounds in the environment and, in particular, for solid matrices. Therefore, the aim of this work was to perform soil column experiments to evaluate the accumulation, transfer and degradation of these substances in soil. The analyses were based on efficient sample preparation followed by sensitive and selective liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). For this purpose, 23 compounds were chosen including both pharmaceutical compounds as well as steroid hormones. In addition, this experiment was performed on two soils with different properties (% clay, pH, etc.). To the best of our knowledge, no soil column experiments have been performed previously on a large number of pharmaceutical compounds and steroid hormones. Significant transfer was observed only for sulphonamides that can be justified by their polarity (log K ow ?3). Furthermore, some compounds have a cationic characteristic and are likely to be not much mobiles in soil due to cation exchange process. However, it was observed that the migration of the substances depends on the soil characteristics, such as the amount of clay and the pH values. Regarding the degradation, it was noticed that substances degraded rapidly in the two soils. Indeed, for most substances, their half-lives were lower than 20 days. Furthermore, it was observed that the degradation rate depended on the soil. 相似文献

To collect a complete dataset regarding the occurrence of organic substances in groundwater, this study presents the examination of 66 organic contaminants in the groundwater of overseas departments, including pesticides, pharmaceutical compounds, hormones and some industrial substances. The selective and sensitive analytical methods are described. These techniques begin with solid-phase extraction (SPE) followed by analysis using liquid chromatography–tandem mass spectrometry (LC-MS/MS) and gas chromatography–mass spectrometry (GC-ToF-MS). The paper summarises the analytical results from 40 sampling points collected during two campaigns in Guadeloupe, Martinique, Reunion, Mayotte and Guiana, representing 80 samples. Of the 66 target substances, 36 were determined at least once. Among the most frequently detected are bisphenol A (frequency, 96 %; max., 7,400 ng/L), caffeine (frequency, 91 %; max., 1,240 ng/L), pentachlorophenol (frequency, 55 %; max., 418 ng/L), and carbamazepine (frequency, 56 %; max., 22 ng/L). The results do not put in evidence that the origin of the sample or climatic characteristics of these regions influence the dilution and release of micropollutants. 相似文献

A national reconnaissance for selected organic micropollutants in sediments on French territory 总被引:1,自引:0,他引:1
Emmanuelle Vulliet Alexandra Berlioz-Barbier Florent Lafay Robert Baudot Laure Wiest Antoine Vauchez François Lestremau Fabrizio Botta Cécile Cren-Olivé 《Environmental science and pollution research international》2014,21(19):11370-11379
To collect a large data set regarding the occurrence of organic substances in sediment, this study presents the examination of 20 micropollutants, as a national survey. The list of target compounds contains two alkylphenols, three polycyclic aromatic hydrocarbons (PAHs) not commonly included in monitoring programmes, six pesticides or metabolites, five pharmaceutical compounds, two hormones, one UV filter and bisphenol A. The selective and sensitive analytical methods, based on quick, easy, cheap, effective, rugged, and safe (QuEChERS) sample preparation followed by liquid chromatography-tandem mass spectrometry (LC-MS/MS) or gas chromatography-time-of-flight mass spectrometry (GC-ToF-MS), allow the quantification at limits comprised between 0.5 and 23 ng/g, depending on the compound. The paper summarizes the analytical results from 154 sampling points. Of the 20 target compounds, 9 were determined at least once, and the sediments contained a maximum of 7 substances. The most frequently detected were PAHs (frequency, 77 %; max., 1,400 ng/g). The pharmaceutical compounds, hormones and pesticides were rarely detected in the samples; the most frequently detected was carbamazepine (frequency, 6 %; max., 31 ng/g). In some cases, the levels of PAHs and bisphenol A exceed the predicted no-effect concentration (PNEC) values. 相似文献
