“…In a study by Ramirez et al [28] in the coast of Campche, Mexico, the concentrations of DBP and DEHP reported reached 20.119 µg/g and 21.098 µg/g, respectively. The samples taken from surface sediments of the coast of such a sea reached the concentrations of 40.87 µg/g of DEHP and 19.20 µg/g of DBP [29]. Furthermore, a similar trend was observed in the study carried out in the Persian Gulf, whereby the concentrations of DEHP and DBP added to a total of 30.25 µg/g and 11.97 µg/g, respectively [24].…”

“…One of the main pressures which affect coastline areas through anthropogenic activity is the introduction of abundant amounts of microplastic debris due to of littering and utilisation of myriad plastic materials [31], which may leach out phthalates in shoreline sand. Phthalates, including DBP, are not chemically bound to plastics and can easily leach, evaporate and migrate through domestic and industrial effluents and indiscriminate disposal of phthalate-containing products [29].…”

DBP and DEHP are two of the most common plasticisers used in modern industries, which have aroused a major concern over their ubiquitous occurrence and hazardous environmental effects. This study presents the first data of phthalates occurrence and distribution in Maltese shoreline sand. DBP and DEHP occurrence was investigated in three busy and secluded beaches, respectively. Analytical determination involved quantifying DBP and DEHP from 75 samples using UPLC–MS/MS through triple repeatability. The concentrations ranged between 0.0095 and 0.07034 µg/g and <LOQ and 0.0977 µg/g for DBP and DEHP, respectively. Statistical analysis of the comparison of phthalates in different beaches demonstrated that the occurrence of DBP and DEHP in Maltese shoreline sand varies. The differences in the occurrence of phthalates were attributed to the beach topography and anthropogenic pressures. Analysis of the effects of anthropogenic activities on the occurrence of phthalates showed a positive association. Distribution analysis showed that DBP and DEHP exhibit an uneven distribution along the shoreline. Conversely, different distributions were observed at distances away from the sea. The uneven distributions observed were associated with anthropogenic activities, different chemodynamic properties and wave action. Cluster analysis was performed to prove the interactions between the phthalates concentrations and the characteristics of the beaches.

“…In these previous studies, DnBP and DEHP were the most predominant compounds. DnBP and DEHP concentrations in sediments of the Bohai and Yellow seas were usually 1-3 orders of magnitude lower than those detected in riverine, estuarine and coastal sediments (Adeniyi et al, 2011;Du et al, 2013;Sha et al, 2007;Stewart et al, 2014;Stoppa et al, 2017;Zhang et al, 2018b;Fatoki et al, 2009;Li et al, 2017;Hassanzadeh et al, 2014;Yang et al, 2016). Zhang et al reported DEP, DiBP, DnBP, and DEHP in the Yangtze River estuary, which showed a comparable level in 2017 and a relatively high level in 2018 in comparison to values in this study (Zhang et al, 2017;Zhang et al, 2018b).…”

“…Over the last two decades, CWs have been used in the removal of several EPs [48][49][50]. However, although CWs have been found to be a successful technology for removing a number of EPs, including caffeine [28,29,31,51], there are fewer studies regarding PEs and TCPP [52][53][54][55][56][57]. The current study intends to focus on the fact that these compounds are often discharged into water bodies (coastal, surface and groundwater) as residual concentrations [32,49].…”

We assessed constructed wetland (CW) performance in the removal of six emerging pollutants (EPs) from university campus wastewater. The EPs considered were: diethyl phthalate (DEP), di-isobutyl phthalate (DIBP), di-n-octyl phthalate (DNOP), bis(2-ehtylxexyl) phthalate (DEHP), tris(1-chloro-2-propyl) phosphate (TCPP) and caffeine (CAF). Six pilot-scale CWs, i.e., three horizontal subsurface flow (HSF) and three vertical flow (VF), with different design configurations were used: two types of plants and one unplanted for both the HSF and the VF, two hydraulic retention times (HRT) for the HSF, and two wastewater feeding strategies for the VF units. The results showed that the median removals in the three HSF-CWs ranged between 84.3 and 99.9%, 79.0 and 95.7%, 91.4 and 99.7%, 72.2 and 81.0%, 99.1 and 99.6%, and 99.3 and 99.6% for DEP, DIBP, DNOP, DEHP, TCPP, and CAF, respectively. In the three VF-CWs, the median removal efficiencies range was 98.6–99.4%, 63.6–98.0%, 96.6–97.8%, 73.6–94.5%, 99.3–99.5% and 94.4–96.3% for DEP, DIBP, DNOP, DEHP, TCPP and CAF, respectively. The study indicates that biodegradation and adsorption onto substrate were the most prevalent removal routes of the target EPs in CWs.
