Determination of phthalate ester plasticizers in the aquatic
INTRODUCTION Phthalate esters are among the most common in- dustrial chemicals. They are needed in the production of various plastics (including PVC), in insect repel- lant preparations, cosmetics, decorative ink, muni- tion, and lubricating oils.
Determination of phthalate ester plasticizers in the aquatic
The separation and detection method for analysing phthalate esters was carried out using a high performance liquid chromatography (HPLC) equipped with diode array detector. The column used in this work was waters C-18 column (250 mm × 4.6 mm, 5 μm). The mobile phase used was acetonitrile and 0.05% orthophosphoric acid in water (92:8, v/v).

Determination of phthalate esters in the aquatic environment
The use of solid phase extraction and capillary GLC provides the basis for selective determination of phthalate ester plasticizers in rivers and marine water samples. Of the several solvent ratios
Determination of Phthalate Esters in the Aquatic Environment
The rivers and marine water samples are grossly polluted as several phthalate esters, for example, dimethyl (DMP), diethyl (DEP), dibutyl (DBP) and diethylhexyl (DEHP) were found present at 0.03 – 2 306 ± 9.4 m gl-1. A study on uncontaminated water was done to establish bank levels. South African Journal of Chemistry Vol.54 2001: 69-83 PDF
- Do plastic products release phthalate esters?
- Plastic properties and external environmental factors can affect the release. Phthalate esters (PAEs) are predominant additives in plastics, their widespread contamination in aquatic environments has raised global concern. Here, twelve plastic products were prepared as microplastics to investigate their release behaviors of PAEs.
- What are phthalate esters (Paes)?
- Phthalate esters (PAEs) are one of the predominant additives extensively integrated into consumer products as plasticizers (Staples et al., 1997). Over 11 tons of PAEs are produced worldwide per minute for the manufacturing of plastic products (Theworldcounts, 2021).
- Do water chemical properties affect the migration of Paes from microplastics?
- Water chemical properties such as pH and salinity could affect the migration of PAEs from microplastics in aquatic environments. The pseudo-first-order model fits well with the leaching behavior of PAEs from microplastics into water.
- Are microplastics a potential source of Paes in aquatic environments?
- This study revealed that microplastics are the potential source of PAEs in aquatic environments, with the estimated annual mass loads between 57.8 and 16,100 kg. Six out of the 15 PAEs, including DMP, DEP, DiBP, DBP, DEHP, and BBP, were detected in water after 14 days of incubation. The leaching abilities of PAEs were plastic type-specific.
- Does water pH affect the leaching of Paes from microplastics?
- Microplastics were added to these solutions and incubated for 14 days. To understand the effects of water pH on the leaching of PAEs from microplastics, the background solution was adjusted to pH 3.0, 5.0, 7.0, 9.0 and 11.0 ± 0.1 using negligible volumes of HCl and NaOH (1 M) solutions, and incubated with microplastics for 14 days.
- Do Paes release into water bodies from plastic products?
- Additionally, it could be speculated that PAEs may also directly release into water bodies from plastic products during their use in contact with water, such as laundry bag (PET), shoe brush (PP), bath ball (PE) and drain pipe (PVC).
