Dibromoacetic acid (DBA) exsits in drinking water as a by-product of disinfection as a result of chlorination or ozonation processes. Hippocampus and pre-frontal cortex are the key structures in memory formation and weanling babies are more sensitive to environmental toxicant

Water disinfection by-products, such as dibromoacetic acid (DBA), are formed when drinking water is treated with chlorination, bromination, or ozonation. Epidemiological studies have linked these byproducts to adverse effects in humans such as cancer, developmental defects, and reproductive toxicities. DBA
