Final answer:
Pharmaceutical residues from veterinary and human use can bind with bioresins, affecting soil and water sources.
Step-by-step explanation:
When it comes to drugs binding with bioresins, one example is pharmaceutical residues. These residues, which can come from excretions during veterinary treatment or human pharmaceutical use, may bind strongly to soil particles. Lipid-soluble pharmaceutical residues have little tendency to leak out to ground water or surface waters, while more water-soluble residues can be washed out with rain or melting snow and reach both ground water and surface water streams.
