Lead poisoning Lead poisoning is a type of metal poisoning caused by lead in the body.[2] The brain is the most sensitive.[2] Symptoms may include abdominal pain, constipation, headaches, irritability, memory problems, inability to have children, and tingling in the hands and feet.[1] It causes almost 10% of intellectual disability of otherwise unknown cause and can result in behavioral problems.[2] Some of the effects are permanent.[2] In severe cases anemia, seizures, coma, or death may occur.[1][2]
Flint water crisis The Flint water crisis first started in 2014 when the drinking water source for the city of Flint, Michigan was changed from Lake Huron and the Detroit River to the cheaper Flint River. Due to insufficient water treatment, lead leached from the lead water pipes into the drinking water, exposing over 100,000 residents. After a pair of scientific studies proved lead contamination was present in the water supply, a federal state of emergency was declared in January 2016 and Flint residents were instructed to use only bottled or filtered water for drinking, cooking, cleaning, and bathing. As of early 2017, the water quality had returned to acceptable levels; however, residents were instructed to continue to use bottled or filtered water until all the lead pipes have been replaced, which is expected to be completed no sooner than 2020.
