Diverse environments are generated from the mixing of various matters from individual Earth System components (lithosphere, atmosphere, hydrosphere and biosphere) at a local scale along with addition of anthropogenic (human/industrial) activities. They are substantially influenced by natural environmental processes (photoinduced, microbial and physical mixing processes) that varied depending on the space and timescale. In such diverse environments to identify biogeochemical consequence/fact and its mechanism, it is important to find out “Selective Characteristic Sample” from each individual source to ascertain specific source matter/elements. Characteristic sources and transformations of fluorescent organic matter, identified by EEM-PARAFAC modeling, could be used to exemplify on individual natural system, environmental key processes and human/industrial activities to outline diverse environments. These results therefore imply that understanding ‘Selective Characteristic Sample’ based on individual all environmental factors at local scale and sampling as accordingly are important to find out any biogeochemical phenomena in diverse environments.
