Maceira, Alba published the artcileOccurrence of plastic additives in outdoor air particulate matters from two industrial parks of Tarragona, Spain: Human inhalation intake risk assessment, SDS of cas: 121-00-6, the main research area is plastic additive industrial park human inhalation intake; Air particulate matter samples; Gas chromatography-mass spectrometry; Human inhalation exposure; Outdoor air; Plastic additives.
Plastic additives include several kinds of chems. that are added to the polymer matrix to improve the final product quality and prevent deterioration effects. They are used in a large quantity of materials, so their presence in the environment is expected. This study has developed and validated a method based on gas chromatog.-mass spectrometry after pressurized liquid extraction to determine sixteen plastic additives including UV-stabilizers, aromatic and phenolic antioxidants and some of their degradation products in particulate matter (PM10) from outdoor air. Apparent recoveries were above 85% for most of compounds and low detection limits (pg m-3) were achieved. This is the first study to determine these types of contaminant in the PM10 of outdoor air from two locations surrounded by different industries. Various compounds were found in almost all samples; BHT, BHT-Q, 2,4-DTBP, BHT-CHO, UV320, UV328, Irgafos168 and Iragonx1076, with concentrations ranging from < MQL to 2860 pg m-3. Estimated daily intakes (EDIs) via ambient inhalation were calculated for each polymer additive and for different subpopulation groups classified by age. Two possible exposure scenarios (low, based on geometric mean, and high, 95th percentile) were simulated, and 0.51 ng kg-1bw day-1 was the EDI in the worst case scenario for children. Journal of Hazardous Materials published new progress about Air pollution. 121-00-6 belongs to class ethers-buliding-blocks, name is 4-Hydroxy-3-tert-butylanisole, and the molecular formula is C11H16O2, SDS of cas: 121-00-6.
