Delno D. Malzahn, CIH, FAIHA
Principal Scientist
Occupational & Environmental Health Risk Assessment
  • Detroit

Mr. Malzahn has more than 40 years of experience in environmental engineering, industrial hygiene and building materials exposure assessment. He has managed and conducted hundreds of exposure studies for wide variety of industries including oil and natural gas, manufacturing, food processing, asphalt, iron and steel and construction. In addition, his expertise includes indoor air quality and mold investigations in residential and commercial buildings. He has extensive management and technical expertise related to EPA and OSHA compliance matters. He has also designed and conducted exposure simulation studies for reconstruction of past occupational asbestos, silica and trace benzene exposures.
