Bisphenol A
(
BPA
) is an environmental endocrine disruptor that seriously threatens ecological systems. Plants are the primary producers in ecological systems, but little information is available concerning the toxic effect of
BPA
on plants. In the present study, the effects of
BPA
on the growth and nitrogen nutrition of roots of soybean seedlings were investigated by using a root automatic scan apparatus and biochemical methods. It was found that when soybean seedlings were treated with 1.5 mg/L
BPA
, the growth of roots was improved, the content of nitrate in roots was increased, the content of ammonium in roots was decreased, and the activities of nitrate reductase and
nitrite reductase
in roots were not changed. The opposite effects were observed in roots treated with 17.2 mg/L and 50.0 mg/L
BPA
, except for an increase in the content of nitrate in roots treated with 17.2 mg/L
BPA
and a decrease in the activities of nitrate reductase and
nitrite reductase
in roots of soybeans seedlings. Statistical analysis indicated that the change in the nitrogen nutrition of roots of soybean seedlings treated with
BPA
was one reason why the growth of roots was changed. The authors suggest that the potential environmental and ecological risk of
BPA
to plants should receive more consideration.
