"In toxicology and medicine, it's understand that excessive pharmaceutical use poses a concern to human health although it's unknown if the same effects could be applied to non-human organisms. Due to the increasing presence of pharmaceuticals in the environment, it becomes increasingly critical to study the potentially negative effects of pharmaceuticals on the environment and non-target species. There has been a general lack of research regarding the impacts of pharmaceuticals on non-target species overall, specifically terrestrial flora, and there isn't a certain conclusion if being exposed to pharmaceuticals proves detrimental to species in which it wasn't intended for. In this experiment, various over-the-counter pharmaceuticals were added to the water source of Phaseolus vulgaris Pinto Group (commonly known as pinto beans) to gauge what kind of impact would be had on the growth. Five groups of pinto beans were germinated and grown in towels exposed to acetaminophen, aspirin, bismuth subsalicylate, ibuprofen, and pseudoephedrine along with an unaffected control group for a period of four weeks, and the resulting lengths of the pinto beans were measured. This research could be an incentive to further study the possible negative impacts of pharmaceuticals on the environment and in turn to help protect the environment."
