Our group is researching, “Which . macroinvertebrate. has the most mercury when compared throughout the trophic pyramid?” . Macroinvertebrates. are insects without a backbone that can be seen with the naked eye.  Mercury is an element that can be found in water, air and soil or sediment. There is more than one specific type of mercury like inorganic, organic, elemental, and metallic (metal). Mercury can also give off toxic vapors which is dangerous for the environment because they are clear, odorless, and invisible, so we don’t even know they are evaporating because we can’t see or smell them.

This stream is a great resource for the UWEC science classes and is used for many field labs and research projects. But is this heavy use damaging the stream and the populations of benthic Steffen Aagaard Sørensen. 1. , . Thomas . Haugland Johansen. 2. , . Juho. . Junttila. 1. .. 1. Department . of Geoscience, .
