Environmental+Contaminants

NORTH HIGH SCHOOL:

Current research looking at impact of environmental contaminants (herbicide, Isoxaben) on growth and development of //Xenopus laevis// tadpoles. We are measuring time to and size at metamorphosis. Tadpoles were reared in treatment concentrations of 0, 25, 50, 100, or 200 micrograms isoxaben/ liter moderately hard water. There are three replicate tanks for each treatment level, with 30 tadpoles per tank.
