These seven (7) things are all that come to mind and I'm not sure if any, all or a combination of them could cause the lymph nodes under my jaw to become moderately sore and swollen. Again, they are not huge, hot to the touch, red, etc and there is no tracking.
Lichens and Air Pollution. One of the most common indicator species used to measure air pollution are lichens. Lichens are similar to fungi and algae, and absorb water and minerals from the air to grow on living and nonliving surfaces.As such, lichens absorb all the pollutants in the environment, and some varieties of lichen survive better in the presence of pollution than others.ichens and Air Pollution.

Some plants and plantlike organisms have developed other pigments to compensate for low light or poor use of light. Cyanobacteria and red algae have phycocyanin and allophycocyanin as accessory pigments to absorbe orange light.rown algae have the pigment fucoxanthin in addition to chlorophyll to widen their absorption range. These red and brown algae grow to depths around 270 meters where the light is less than 1% of surface light. But the most advanced plants are the land plants, which have the least advanced system for gathering light!
