We hypothesize that 1) ibuprofen will decrease snail growth, movement, and reproduction by affecting energy allocation due to oxidative stress and neurotoxicity, 2) microplastic exposure will impair metabolic processes (i.e., digestion through physical blockage), reducing growth, movement, and reproduction, and 3) combined exposure will have a greater negative effect on these endpoints than ibuprofen or microplastics alone
