We measured eight metabolites of four parent compounds: monobenzyl phthalate (MBzP, a metabolite of BBzP); four metabolites of DEHP [mono(2-ethylhexyl) phthalate (MEHP), mono(2-ethyl-5hydroxyhexyl) phthalate (MEHHP), mono(2-ethyl-5-oxohexyl) phthalate (MEOHP), and mono(2-ethyl-5-carboxypentyl) phthalate (MECCP)]; monocarboxyoctyl phthalate (MCOP; a metabolite of DiNP); monocarboxynonyl phthalate (MCNP; a metabolite of DiDP); and mono(3-carboxypropyl) phthalate (MCPP; a metabolite of several HMW phthalates and a minor metabolite of dibutyl phthalate).
All the investigated calibration curves were obtained by the acceptable correlation coefficients ([R.sup.2] > 0.99) at five concentrations ranging from 0.05 to 5 [micro]g/g for DBP, BBP, DEHA, DEHP, DNOP, and DOTP and from 0.15 to 15 [micro]g/g for DINP and DIDP, respectively.
In the most recent one, described in the journal Hypertension online July 9, the investigators report a "significant association" between high blood pressure and the presence of DINP and DIDP levels in study subjects.
The rate of absorption of the petroleum-derived plasticizers was dependent on their molecular weights; TOTM was the slowest to absorb (4 min at 50 phr), DOP was the fastest to absorb (2 min at 50 phr; 3 min at 83 phr), and DIDP fared in-between (3 min at 50 phr).
Low molecular weight phthalates, for example di-methyl phthalate (DMP), DBP, are present in cosmetic products (nail polish, perfumes, facial creams, shampoos, body lotions ...), while high molecular weight phthalates, for example DEHP, BBzP, DNOP, DINP, DIDP, are present in plastic containers, adhesives, clothes of raincoat type and plastic products with polyvinyl chloride which is added in order to improve flexibility [4].

Although inhalation is not the primary exposure pathway for SVOCs, dermal exposure and oral ingestion depend strongly on concentration of gas-phase SVOCs, so the air change rate still has a strong influence on total exposure for relatively light SVOCs (DBP, BBP and DIDP in Figure 3).
The health department on Monday said tests revealed the British firm s Augmentin antibiotic tablet contained several plasticisers, including diisodecyl phthalate (DIDP), raising "quality concerns."
Batches of the drug were recalled in the Hong Kong and Taiwan as they were said to contain an unsafe chemical additive, known as diisodecyl phthalate (DIDP) which could induce adverse side-effects in children.
The agency also mentioned that the Hong Kong government had said that tests done on Augmentin syrup -- a joint British, French product -- contained unsafe plastic products known as DIDP.
