In areas where river deltas inject organic material and dissolved trace elements into the sea, for instance, it's not clear how all of the intricately related processes will affect water chemistry.
Tunable diode laser absorption spectroscopy has been applied in the fields of atmospheric chemistry and monitoring pollutant gases as a new method of measuring trace gases.
Urbanization has caused a large amount of emissions of trace gaseous pollutants, aerosols and ozone precursors, inducing the disturbance in regional atmospheric chemistry circulation.
