Recognizing the increasing threat of acid deposition inn soil through the reaction of NOx and SO₂ pollutants with water in Spain, the authors investigates the effects of Al(NO₃)₃ concentrations on the health of Allium sativum. By tracking its mitotic index, they found a negative exponential correlation between Al(NO₃)₃ concentrations and the mitotic index of A. sativum.

In this study, the authors determined whether tautomerization dynamics in protic and aprotic solvents displayed differences in reaction rates and in the proportion of the keto and enol tautomers present.

Androgens are natural or synthetic steroid hormones that control secondary male sex characteristics. Androgens are excreted in cattle urine and feces, and can run off or seep into nearby waters, negatively impacting aquatic life and potentially polluting human water sources. Here, the authors investigated the effectiveness of soil as a natural barrier against androgen flow into vulnerable waterways. Their results, obtained by testing diffusion patterns of luminol, an androgen chemical analog, indicated that soil is a poor barrier to androgen diffusion.
