Phthalate Risks and Alternatives | Center for Advanced Life
Also, DINP, DIDP, and DNOP would also be essentially banned with the new restrictions. In 1999, a risk assessment of DINP, DEHP, DBP, and BBP showed that DINP had essentially no reproductive risks associated with it. Even though there is evidence to support the low risk of DINP, the EU has unanimously decided to ban the phthalate from toys.

- Do alternative plasticizers contaminate Lake and coastal sediments?
- DEHP, DEHTP, and DiNP predominate in lake and coastal sediments. Contamination patterns of alternative plasticizers depend on the type of industries. Mass inventories of plasticizers in lake sediment were 25 times higher than in a bay. Hydrophobicity was a major factor for mobility of plasticizers in the aquatic environment.
- Which lake in Korea has the highest replacement ratio?
- Although contamination by plasticizers was relatively low, Lake Sapgyo had the highest replacement ratio (2.3) in sediments, followed by Lakes Hwaseong (1.4), Namyang (1.3), Asan (0.7) and Asan Bay (1.1). Lake Sapgyo is influenced by the manufacturing of LCDs and automobiles, which are major export products in Korea.
- Are sedimentary plasticizers transported from lakes to the Bay?
- The profiles of LPs and APs in sediment from the lakes and bay were similar to each other. This suggests that sedimentary plasticizers are transported from the lakes to the bay, based on the dilution effects. Among LPs, DEHP was a predominant compound in all sediment from the lakes and bay due to higher consumption trends and hydrophobicity.
- Does DEHP contamination affect benthic ecosystems?
- Our findings imply that DEHP contamination is much riskier to benthic ecosystems in aquatic environments compared with other LMM phthalates, such as DnBP. The SQGs in our study were proposed because of adverse health effects on benthic organisms dwelling in coastal waters.
