Separation of emitted and photochemical formaldehyde in Mexico City using a statistical analysis and a new pair of gas-phase tracers
Photochemical pollution control strategies require an BOOKS understanding of photochemical oxidation precursors, making it important to distinguish between primary and secondary sources of HCHO.Estimates for the relative strengths of primary and secondary sources of formaldehyde (HCHO) were obtained using a statistical regression analysis with time
