Copper exposure can cause immediate symptoms such as irritations to the eyes, nose, and mouth, headaches, stomach aches, dizziness, vomiting, and diarrhea, while chronic toxicity targets the liver, leading to conditions like Wilson disease and cirrhosis syndromes. The study emphasizes the importance of ongoing research and monitoring to identify pollution sources and implement effective measures, facilitating the restoration of the Imus River. The study aims to detect copper concentration in sediment samples from the Imus River using Flame Atomic Absorption Spectroscopy (FAAS) and compare it to EPA limits. The findings revealed consistently elevated copper concentrations in sediment samples collected between July 2 and August 20, surpassing the EPA’s threshold of 50 ppm. This persistent exceedance underscores the basis for the need for further assessment.
