Occurrence and Removal of Estrogenic Short-Chain Ethoxy Nonylphenolic Compounds and Their Halogenated Derivatives during Drinking Water Production

Environmental Science & Technology (2003)

Mira Petrović Alfredo Rubio Díaz Francesc Ventura ‪Damià Barceló

The elimination of nonylphenol (NP), nonylphenol mono- and diethoxylates (NP1EO and NP2EO), nonylphenol carboxylates (NP1EC and NP2EC) and their brominated and chlorinated derivatives during drinking water treatment process in Sant Joan Despí waterworks in Barcelona was investigated utilizing a recently developed, highly sensitive LC−MS−MS method. The concentration of these potentially estrogenic compounds in raw water entering waterworks (taken from the Llobregat River, NE Spain) ranged from 8.3 to 22 μg/L, with NP2EC being the most abundant compound. Prechlorination reduced the concentration of short-chain ethoxy NPECs and NPEOs by about 25−35% and of NP by almost 90%. However, this reduction of concentrations was partially due to their transformation to halogenated derivatives. After prechlorination, halogenated nonylphenolic compounds represented approximately 13% of the total metabolite pool, of which 97% were in the form of brominated acidic metabolites. The efficiency of further treatment steps to eliminate nonylphenolic compounds (calculated for the sum of all short-chain ethoxy metabolites including halogenated derivatives) was as follows: settling and flocculation followed by rapid sand filtration (7%), ozonation (87%), GAC filtration (73%), and final disinfection with chlorine (43%), resulting in overall elimination ranging from 96 to 99% (mean 98% for four sampling dates). A few of the nonylphenolic compounds (NP, NP1EC, and NP2EC) were also identified in drinking water; however, the residues detected were generally below 100 ng/L, with one exception for NP2EC in November 2001 when a concentration of 215 ng/L was detected.

Objective: Patients with sleep apnoea-hypopnea syndrome show very high levels of sympathetic activity, which may affect both short-term and long-term blood pressure regulation. Spectral analysis of heart rate variability allows simple, non-invasive testing of the autonomic function. Aim was to determine the level of sympathetic activity using spectral analysis of HRV in hypertensive patients with/without SA. Design and method: Research included 100 patients who underwent polysomnograpic examination in UCC Kragujevac. According to apnoea-hypopnea index (AHI) all patients were divided into 3 equal groups, 25 patients in each group (AHI 5–15; 15–30 and > 30). Fourth group was a control group with 25 patients without SA. All patients were evaluated for prior hypertension and antihypertensive therapy. Diagnosis was confirmed using ABPM and HTN was classified according to the latest guidelines. Spectral analysis of HRV was used for non-invasive testing of autonomic function. The analysis was performed using a fast Fourier transform of the autoregression method integrated into 24 h ECG Holter monitoring. All data were statistically analyzed in the SPSS for Windows. Results: Study population consisted of 69% of male and 31% of female patients with mean age of 55.05 ± 11.16 years. Prior hypertension was present in 76% of patients (x2 = 27.04; p = 0.000), with 68% on antihypertensive therapy (x2 = 12.96; p = 0.000). Among patients with diagnosed SA 62% had hypertension (x2 = 7.31; p = 0.007). More than 50% of patients had beta blockers in their therapy in total popultion and 46% in group with SA. Spectral analysis of HRV showed higher sympathetic activity: LF component – 984.29 ± 3893.04 vs HF component – 464.04 ± 1938.75. LF/HF ratio was >2.0 in 70% of patients confirming that autonomic balance is shifted towards sympathetic activity (x2 = 12.96; p = 0.000). Among patients using beta blockers 66.1% had higher sympathetic activity. Conclusions: As previously described, males have sleep apnoea-hypopnea syndrome more often than females. More than a half of patients with sleep apnoea had prior hypertension. Autonomic balance was shifted towards sympathetic activity. Although majority of patients in both groups, total and patients with sleep apnea, had beta blockers in therapy, sympathetic activity remained higher.

Quantitative Chromatographic Analysis by Color Analyzer Datacolor 3890

Mira Petrović Ljerka Bokić Sandra Andrašić Marija Kaštelan‐Macan

Color analyzer Datacolor 3890, orginally designet for textile industry, is a powerful tool in analyzing and quantifying analytes that give colored chromatographic spots. Although many analytes lack conveinient chromatophores, using of numerous post chromatographic chemical reactions results in colored spots that can be easily analyzed.

Identification of emerging contaminants in greywater emitted from ships by a comprehensive LC-HRMS target and suspect screening approach

Environmental Pollution (2024)

Rubén Gil‐Solsona Rubén Gil‐Solsona E Mikkolainen M Hytti Erik Ytreberg

The increase in maritime traffic has led to substantial greywater discharges into the marine environment. Greywater, originating from sinks, showers, kitchen, and laundry facilities, contains a wide array of chemical contaminants influenced by on-board activities, ship size, and management practices. The lack of comprehensive regulations for greywater management, along with limited research on its chemical composition, highlights the need to characterize these waste streams. This study is one of the first to provide a comprehensive characterization of greywater samples from ships using advanced liquid chromatography coupled to high-resolution-mass-spectrometry (LC-HRMS) strategies, including wide-scope target and suspect screening. The target analysis detected 86 compounds, such as pharmaceuticals, stimulants, tobacco and food-related products, personal care products, UV filters, surfactants, perfluoroalkyl compounds, plasticizers, and flame retardants, many of which are rarely measured in routine monitoring programs. Furthermore, 11 additional compounds were tentatively identified through suspect screening. A novel scoring system further highlighted 25 priority compounds posing ecological risks to marine ecosystems, including pharmaceuticals such as tapentadol, dextrorphan, citalopram, or irbesartan. This study emphasizes the significant introduction of chemicals at μg L
