“…Furthermore, this dilution gradient suggests the efficient dispersal of additives in the sediments across the Rhône's discharge area. Total PAE (∑ PAEs) concentrations (DEP, DiBP, DnBP, BBP, DCHP, and DEHP) were reported at similar levels (1.37 to 24.6 ng/g DW) in the sediments from the Bohai and Yellow Seas (Mi et al, 2019), and at slightly higher levels (17-530 ng/g DW) for the Jiulong River (Li et al 2016). The highest concentrations…”

“…3a). DEHP was also shown to be the most abundant PAE in the sediments of the Bohai and Yellow Seas (with maximum DEHP concentrations of 15.9 ng/g DW and 15.6 ng/g DW, respectively, Mi et al, 2019), as well as in the sediments of Taihu Lake, China (Wang et al, 2003), of the Qiantang River, China (Sun et al, 2013), and of the Pearly River, China (Liu et al, 2014) where concentrations were 10 times higher.…”

Seven phthalate (PAEs) and nine organophosphate esters (OPEs) were measured in surface sediments across the Gulf of Lion (NW Mediterranean Sea) at twelve stations characterized by different anthropogenic signatures. ∑PAEs and ∑OPEs concentrations ranged from 2 to 766 ng/g DW (av. 196 ng/g DW) and from 4 to 227 ng/g DW (av. 54 ng/g DW), respectively. Our analysis of the potential sources of these organic plastic additives in sediments of the Gulf of Lion suggests that the dominant factors affecting their occurrence and environmental distribution are portbased industrial activities and urban pressures. Indeed, the highest ∑PAE and ∑ OPE concentrations were found close to the ports of Toulon and Marseille (Estaque) and at the sites impacted by the Marseille metropolitan area (i.e. at the outlets of the waste water treatment plant at Cortiou and at the mouth of the Huveaune River). The lowest levels were generally found in protected areas (e.g. Port-Cros) and at sites relatively far from the coast. DEHP was seen to be the most abundant PAE while TDCP, TEHP and TiBP were the most abundant OPEs in the area. Our results also expose the contribution of additives entering the Gulf of Lion via sedimentary material from the Rhône River, with positive correlations 3 between the total organic carbon (TOC) content in the sediment and the ∑PAEs and ∑OPEs concentrations. However, additive concentrations decreased from shore to offshore in the Rhône River discharge area, indicating an efficient dilution of the contaminants accumulated at the river mouth area.

“…In light of the above, an array of literature has investigated the temporal and spatial distribution of these compounds in different aquatic ecosystems to demonstrate the presence and distribution of these compounds in different countries globally (Paluselli et al, 2018;Abtahi et al, 2019;Mi et al, 2019;He et al, 2020;Ai et al, 2021). Furthermore, studies in the past decade that have reported the presence of PEs in aqueous and edaphic matrices including their concentration levels as reported in Tables 2, 3.…”

Phthalate esters (PEs) are by far the most produced and extensively used synthetic organic chemicals with notable applications in many industrial products such as vinyl upholstery, adhesives, food containers, packaging materials, printing inks, adhesives, cosmetics, paints, pharmaceuticals munitions, and insecticides among other. PEs have long been recognised as ubiquitous organic pollutants of prime environmental concern, with urbanisation amongst the main cause and source of these compounds. Due to their notoriety, these compounds are known to pose devastating effects to living organisms including humans. The presence of PEs and their metabolites in the aquatic ecosystems is of concern primarily due to their endocrine disrupting and carcinogenicity properties. Several research studies have reported prevalence, exposure pathways, toxicity, and impacts of PEs in aquatic ecosystems and humans. Their principal routes of exposure could be direct or indirect, of which the direct route include contact, eating, and drinking contaminated foods, and the indirect route constitute aerosols, leaching and other forms of environmental contamination. PEs find way into water systems through means such as effluent discharges, urban and agricultural land runoff, leaching from waste dumps and other diffuse sources. High-end instrumentation and improved methodologies on the other hand have resulted in increased ability to measure trace levels (μg/L) of PEs and their metabolites in different matrices and ecological compartments of water or aquatic ecosystems such as lakes, oceans, rivers, sediments, wetlands and drinking water samples. In light of the above, this article provides an informed and focused information on the prevalence of phthalate esters in aquatic systems and related effects on living organisms and humans. Furthermore, techniques that have enabled the extraction and analysis of these PEs in aquatic samples are also explained. Future research outlooks and needs are also highlighted in this manuscript. This information will be used to better understand their temporal and spatial distributions in the aquatic systems and aid in devising prudent means to curtail their ecological footprints.

“…Due to Chinese rapid urbanization and industrialization, rivers are increasingly threatened by all kinds of pollutants (Zhao et al, 2018). Riverbed sediments as important sinks and sources for pollutants, the concentration of pollutants in it has a great impact on aquatic organisms and the water environment, even in uence the entire ecosystem (Mi et al, 2019;Hu et al, 2020).…”

Distributions and compositions of six phthalic acid esters (PAEs), eight phenol compounds and seven heavy metals in riverbed sediments of the Xihe River in Shenyang, China. The ecological risks of these typical pollutants were investigated and evaluated based on the risk quotient (RQ) and potential ecological risk index (PERI) methods. The concentrations of total ∑6PAEs, ∑8phenols and ∑7heavy metals in sediments varied from 92.83 to 293.66 μg/g dw, 8.87 to 83.73 μg/g dw and 0.46 to 419μg/g dw. The main pollutants in Xihe River sediments are DEHP, DIBP, phenol, P-methylphenol and Cd. More than half target PAEs and phenol compounds in sediment of the Xihe River exhibited medium or high ecological risk. Cd poses a very high ecological risk to the Xihe River Basin. It is imperative to take some effective measures to reduce the pollution of those contaminants.
