Phthalates and alkylphenols in industrial and domestic effluents: case of Paris Conurbation (France).
The Science of the total environment, 2014Co-Authors: A. Bergé, J. Gasperi, V. Rocher, L. Gras, A. Coursimault, R. MoilleronAbstract:Phthalates and alkylphenols are toxics classified as endocrine disrupting compounds (EDCs). They are of particular concern due to their ubiquity and generally higher levels found in the environment comparatively to other EDCs. Industrial and domestic discharges might affect the quality of receiving waters by discharging organic matter and contaminants through treated waters and combined sewer overflows. Historically, industrial discharges are often considered as the principal vector of pollution in urban areas. If this observation was true in the past for some contaminants, no current data are today available to compare the quality of industrial and domestic discharges as regards EDCs. In this context, a total of 45 domestic samples as well as 101 industrial samples were collected from different sites, including 14 residential and 33 industrial facilities. This study focuses more specifically on 4 phthalates and 2 alkylphenols, among the most commonly studied congeners. A particular attention was also given to routine wastewater quality parameters. For most substances, wastewaters from the different sites were heavily contaminated; they display concentrations up to 1200 μg/l for di-(2-ethylhexyl) phthalate and between 10 and 100 μg/l for diethyl phthalate and nonylphenol. Overall, for the majority of compounds, the industrial contribution to the flux of contaminant reaching the wastewater treatment plants ranges between 1 and 3%. The data generated during this work constitutes one of the first studies conducted in Europe on industrial fluxes for a variety of sectors of activity. The study of the wastewater contribution was used to better predict the industrial and domestic contributions at the scale of a huge Conurbation heavily urbanized but with a weak industrial cover, illustrated by Paris. Our results indicate that specific investigations on domestic discharges are necessary in order to reduce the release of phthalates and alkylphenols in the sewer systems for such Conurbations.

Urban pathways of biocides towards surface waters during dry and wet weathers: Assessment at the Paris Conurbation scale
Journal of Hazardous Materials, 2021Co-Authors: Claudia Paijens, Adèle Bressy, Bertrand Frère, Damien Tedoldi, Romain Mailler, Vincent Rocher, Pascale Neveu, Régis MoilleronAbstract:Eighteen biocides used in building materials and domestic products were monitored in wastewater treatment plants (WWTPs) during dry weather and in combined sewer overflows (CSOs) during wet weather in the Paris Conurbation. The aims of this study were to (i) acquire data on biocides in urban waters, which are very scarce up to now, (ii) identify their origins in CSOs with the perspective of reducing these contaminants at source, and (iii) compare and rank biocide pathways to the river (dry vs. wet weather) at the annual and Conurbation scales. The results showed the ubiquity of the 18-targeted biocides in WWTP waters and CSOs. High concentrations of methylisothiazolinone, benzisothiazolinone (0.2-0.9 µg/L) and benzalkonium C12 (0.5-6 µg/L) were measured in wastewater. Poor WWTP removals (< 50%) were observed for most of the biocides. Both wastewater (mainly domestic uses) and stormwater (leaching from building materials) contributed to the CSO contamination. However, benzisothiazolinone mainly came from wastewater whereas diuron, isoproturon, terbutryn, carbendazim, tebuconazole, and mecoprop mainly came from stormwater. Annual mass loads discharged by WWTPs and CSOs into the Seine River were estimated using a stochastic approach (Monte Carlo simulations) at the Conurbation scale and showed that WWTP discharges are the major entry pathway.

Relating urban development and densification to temporary changes in the air temperature in Warsaw (Poland)
Theoretical and Applied Climatology, 2020Co-Authors: Tomasz Rozbicki, Grzegorz Majewski, Małgorzata Kleniewska, Katarzyna Rozbicka, Dariusz GołaszewskiAbstract:The assessment of the influence of urbanisation effects on air temperature trends has been widely discussed in the literature. Urbanisation affects the urban active surface energy balance, resulting in the formation of urban heat island, also observed in the Warsaw Conurbation. This article presents the diversity of long-term changes in air temperature at three Warsaw meteorological stations situated in the districts of Ursynów, Okęcie and Bielany, and demonstrates changes in thermal conditions during a long-term urbanisation process. Ursynów is the station where the changes of the surrounding area were most significant among the three analysed ones and the rise in the air temperature for this station was the greatest and it was observed from 7.5 °C in the years 1961–1970 to 8.5 °C in the years 2001–2010. The diversity of air temperature between the stations depends on their location. All of them are situated within the Conurbation, at some distance from the city centre but the nature of their surroundings is different. The diversity applies to all annual characteristics of air temperature: its mean, mean maximum and mean minimum values.

The effect of urban Conurbation on the modification of human thermal perception, as illustrated by the example of Warsaw (Poland)
Theoretical and Applied Climatology, 2013Co-Authors: Grzegorz Majewski, Wiesława Przewoźniczuk, Małgorzata KleniewskaAbstract:As proven by scientific research, urban Conurbations of a size similar to the Warsaw Conurbation generate urban heat islands of an intensity of 1.5–2.5 °C, which results in changes of biometeorological conditions. It was stated that with increased distance from the city centre, the number of cold and very frosty days also increased, which is the result of the mitigating influence of UHI on thermal conditions in the city centre. The difference in the number of cold days between central and peripheral stations amounted to 15–30 %. The obtained distribution of a Conurbation’s thermal conditions is reflected in the spatial distribution of the obtained values of effective temperature. In the case of ‘warm’ sensations, the frequency decreases as the distance from the centre increases, and in the case of ‘cold’ sensations, the frequency increases with increased distance from the city centre.
