Scientist
Oakland

Dr. Xinze Peng is an Air Quality Scientist in Exponent with five years of experience in air quality related environmental health research and air quality monitoring. He has technical expertise and experience in exposure chamber studies with animals, field test projects with both indoor air quality and ambient air monitoring. His research projects in collaboration with the UC Riverside School of Medicine had discovered brain responses associated inhaled nano-particles for the first time and the significant underestimation of previous medical studies using the traditional intranasal treatment.

Prior to joining Exponent, Dr. Peng received his Ph.D. degree in Chemical & Environmental Engineering with a specialization in Air Quality Engineering from the Center for Environmental Research & Technology (CERT) at UC Riverside, where he conducted his research in multiple ambient air monitoring studies, evaluation of Secondary Organic Aerosol (SOA) formation from both marine vessels and passenger vehicles, Diesel Exhaust Particles (DEPs) sampling and collection and inhalation exposure studies of animals in a large scale environmental chamber. He also received his B.S. in Architecture Environment and Equipment Engineering from the University of Science & Technology, Beijing.

Project Experience

  • Collected and analyzed samples of fire residue from a waste and recycling center

Three types of samples were collected after meteorological data analysis. Total of ~200 samples were collected, including Tape Samples and Bulk Samples for Optical Analysis, Tape Samples for Scanning Electron Microscopy (SEM) analysis and Wipe Samples for VOC analysis

  • Fence line and permit compliance monitoring

Conducted fence line monitoring in a landfill site for PM10 and NOx from construction work of heavy duty diesel operation vehicles. Meteorological stations were setup along with continuous PM10/NOx monitoring with all data transmitted via wireless connection.

  • Conducting studies on health effects of atmospheric contaminants on mice

A 540 L complex chamber system made of transparent acrylic sheets was built to conduct whole-body aerosol exposure experiments on mice with multiple air pollution sources. The system provides for controlled and well characterized whole animal exposures where dosage is by inhalation.

  • On-road real-time testing and data mapping for HONDA R&D North America

A mobile laboratory based on a cargo van was built for conducting real time atmospheric contaminants measurements and GIS data mapping. This mobile laboratory was brought to Long Beach industrial area/Pacific Coast Highway(PCH), dairy farms in Eastvale and Southern California freeways to measure the real-time concentration with coordinates of these atmospheric pollutants for evaluation of potential damage on the fuel cell car engine.

  • Estimation of SOA formation aged from generator emissions using B100 and D2 diesel fuels in a Teflon chamber for Air Pollution Models

Diluted diesel generator exhaust was injected into a smog chamber along with H2O2/O3/Surrogate Chemicals to see SOA yield and product composition under UV lights.

  • Collected Diesel Exhaust Particles (DEPs) with a large size impactor collector for health studies in UCLA

Diesel PM was collected from a back-up generator (BUG) exhaust through a dilution tunnel at different engine loads, a total of 1-gram Diesel PM in 3 different sizes was collected.
