“…As widely used compounds, PAEs are ubiquitous in terrestrial, marine and atmospheric environments (Xie et al, 2007;Fu et al, 2013;Dargnat et al, 2009;Gao et al, 2014;Staples et al, 1997;Net et al, 2014;2015a-b;Wang et al, 2014). PAEs have been detected in surface seawater (Turner and Rawling, 2000;Horn et al, 2004;Brossa et al, 2005), in indoor air (Becker et al, 2004), in urban environments in soils (Ferreira and Morita, 2012), in urban lakes (Zeng et al, 2008), in drinking water (Yang et al, 2014), in terrestrial and marine remote aerosols (Xie et al, 2006(Xie et al, , 2007Fu et al, 2008Fu et al, , 2009Fu et al, , 2013, and in marine sediment, as well as in biota, including several aquatic species (Wofford et al, 1981), algae (Gao and Chi, 2015), and the tissues of mammals (Staples et al, 1997) and humans (Liou et al, 2014). PAEs can be degraded by some microalgal species (Gao and Chi, 2015), fish and shellfish (Munshi et al, 2013), bacteria (Chang et al, 2004) and intracellular and extracellular algal enzymes (Gao and Chi, 2015) as well as by the combined action of UV and H 2 O 2 (Xu et al, 2007).…”

International audiencePhthalate acid esters (PAEs) which are mainly anthropogenic molecules with endocrine disrupting effects in animals and humans, have been detected in terrestrial and aquatic environments. However, little is known about their distribution in the Mediterranean Sea, mainly because of analytical difficulties and the high possibility of ambient sample contamination. Here, we report the optimization of an existing protocol for the determination of PAEs in seawater and freshwater samples, as well as the first estimation of the source and distribution of phthalates acid esters (PAEs) in coastal waters from the NW Mediterranean Sea. By passing 1 L of sample through glass cartridges packed with 200 mg of Oasis HLB and eluted with 6 mL of ethyl acetate followed by gas chromatography and mass spectrometry (GC/ MS) analyses, the recoveries for DMP, DEP, DPP, DiBP, DnBP, BzBP, DEHP and DnOP were 101, 98, 115, 110, 99, 98, 103 and 95%, respectively, with acceptable blank values (below 0.4–4.0% of the masses mea- sured in different seawater samples). By using this method, we detected PAEs in the Marseilles coastal area, offshore (2000 m depth) and in the Rhone River with total concentrations ranging from 75.3 ng/L offshore in surface water to 1207.1 ng/L a few meters above the bottom of the Marseilles Bay. High con- centrations were also observed in deep waters offshore (310.2 ng/L) as well as in the Rhone River (615.1 ng/L). These results suggest that Marseilles urban area, Rhone River and sediment are potential sources of PAEs in the areas studied.In the Rhone River, DEHP was the most abundant PAE (66.1%) followed by DiBP (20.5%) and DnBP (6.6%), whereas a gradual change was observed in the plume of the river with increasing salinity. In the Marseilles Bay, DiBP was the most abundant PAE at the surface (47.3% of total PAEs) followed by DEHP (22.7%) and DnBP (19.1%), whereas DnBP was predominant (38.6%) a few meters above the bottom. By contrast, DEHP was the dominant species in the first 50 m (66.9–76.7%) offshore followed by DnBP (10.9–15.2%), whereas DnBP was the most abundant (57.0–72.6%) followed by DEHP (20.1–33.1%) in the deepest waters. This study suggests that in addition to direct PAEs injection in marine waters, differ- ent processes regulate PAE distribution in Mediterranean Sea including photochemical oxidation reac- tions, bacterial degradation and possible diffusion following release from marine litter near the bottom

“…After their introduction in the environment, they can reach marine water by wastewater and riverine inputs, and end up in the sediment via association with humic acid and adsorption onto particles and finally end up in the sediment. 21 Due to the physiochemical properties and biogeochemical cycling of PAEs, they have been detected in food, air, water, soil and sediment 6, [22][23][24][25][26][27][28][29][30][31][32] . However, there is a lack of data related to their sources, distribution in the whole water column as well as their transfer mechanisms from the molecular state to different living species.…”

Phthalic Acid Esters (PAEs) are a group of emerging organic contaminants that have become a serious issue because of their ubiquitous presence and hazardous impact on the marine environment worldwide. Seawater samples were collected monthly from December 2013 to November 2014 in the northwestern Mediterranean Sea (Marseille Bay). The samples were analyzed for dissolved organic carbon (DOC) as well as the molecular distribution of dissolved PAEs by using solid phase extraction followed by gas chromatography and mass spectrometry (GC/MS) analyses. The results demonstrated the occurrence of six PAEs, including dimethyl phthalate (DMP), diethyl phthalate (DEP), di-isobutyl phthalate (DiBP), di-n-butyl phthalate (DnBP), benzylbutyl phthalate (BzBP) and diethylhexyl phthalate (DEHP), with total concentrations ranging from 130 to 1330ngL (av. 522ngL). In Marseille Bay, the highest concentrations were detected in the bottom water from June to November 2014 and in the whole water column during the winter mixing period. This result suggests that resuspension of PAE-rich sediment, in relation to the accumulation of plastic debris above the seabed, or the higher degradation rate in the upper layer of the water column, plays a significant role in the PAE dynamics in coastal water. DEHP was the most abundant PAE in all of the surface samples and the summer bottom samples, followed by DiBP and DnBP, which also represent the largest fractions in the other bottom samples.

“…A typical example of PAEs is di‐(2‐ethylhexyl) phthalate (DEHP), which is a component of flexible polyvinyl chloride (PVC) products. The content of DEHP in flexible PVC products could reach 40% (Ferreira & Morita, ; Erythropel et al ., ; Zolfaghari et al ., ). In 2007, approximately 1 million tonnes of plasticizers were consumed in Europe, and the total production of DEHP was 341 000 t. The demand for plasticizers in Asia is approximately 3.5 times greater than that in Europe; 345 000 t of DEHP was produced in Korea alone in 2010 (Lee et al ., ).…”

“…Currently, the region produces 14% of the total crop production and 40% of the total soya bean ( Glycine max (L.) Merr) production in China; therefore, it is considered an important soil for Chinese crop production (Xu et al ., ). Di‐(2‐ethylhexyl) phthalate tends to accumulate in soil (Cartwright et al ., ; Ferreira & Morita, ) because of its poor solubility in water and large octanol/water partition coefficient. The use of plastic agricultural films is one of the important sources of PAEs in agricultural soil.…”

Summary One of the most common persistent organic pollutants is di‐(2‐ethylhexyl) phthalate (DEHP), which has caused considerable pollution in the Mollisols of agricultural areas in northeast China. This research investigates the effects of different concentrations of DEHP from 0 to 35 days on microbial biomass carbon (MBC) and structural diversity in the microbial community of Mollisols. The results indicated that contamination by DEHP of more than 20 mg kg−1 could clearly affect MBC and structural diversity of the microbial community of a Mollisol in a short time depending on the dose of DEHP. At concentrations of DEHP >20 mg kg−1, we observed that the larger was the concentration of DEHP, the greater was the effect on the MBC and diversity of the soil microbial community. The DEHP concentration or incubation time had negative correlations with MBC, and the evenness (EH), Shannon (H) and richness (S) indices of the microbial community, and the DEHP concentration had a dominant effect on microbial properties. The dominant bacterium in the DEHP‐contaminated soil was Bacillus. Furthermore, bacterial community structure changed under different amounts of DEHP stress and with the increase in incubation time; Pseudomonas and Sphingopyxis clearly increased in number with large concentrations of DEHP. The change in the microbial population indicated that these two bacteria might have a strong resistance to change under the microbial DEHP stress. Highlights DEHP significantly changed MBC and microbial diversity of a Mollisol. The change in MBC was related to the composition of the soil microbial community structure. DEHP had a persistent effect on the microbial community in a Mollisol. Bacillus were the dominant bacteria in the DEHP‐contaminated soil.
