Naphthalene exerts substantial nontarget effects on soil nitrogen mineralization processes in a subalpine forest soil: A microcosm study
Fig 5
Soil enzyme activities in subalpine forest soil microcosms treated with and without naphthalene.
The values represent the means ±the standard error (SE) (n = 5). Asterisks indicate significant (*P<0.05) differences between the treatments with naphthalene and without naphthalene at the same sampling time.
