Vulgaris to magnetic treatment The Superoxide anion in algae cell increased and antioxidant ability was declined by a suitable magnetic treatment. There was different response of the enzymic component-Superoxide dismutase , Catalase , and peroxidase enzyme, and their activities were induced to increase. There was no much response for the nonenzymic component-glutatnione to the magnetic treatment, while content of carotenoid was reduced remarkably with the increasing magnetic intensity and time.

Mineral magnetic parameters, including magnetic susceptibility, frequency dependent susceptibility, isothermal remanent magnetization, anhysteretic remanent magnetization, temperature-dependence of susceptibility, were measured on quartzite and surface soil derived from quartzite. The results in combination with the microscope observation indicated little magnetic mineral in quartzite but a few magnetite, maghemite, iron oxyhydroxides in surface soil. The magnetic grains were mainly superparamagnetic and stable single domain. Maghemite is secondary mineral formed in the process of pedogenesis.
