High blood levels of lead have been linked to a wide variety of health problems, including severe gastrointestinal, neuromuscular, and neurological symptoms. [ 5 ] [ 6 ] These problems are especially significant in children, and childhood lead poisoning can lead to behavioral problems, developmental disorders, and permanent decreases in IQ.
Between the blood lead levels of 5 and 35 μg/dL, an IQ decrease of 2–4 points for each μg/dL increase is reported in children. [42] However, studies that show associations between low-level lead exposure and health effects in children may be affected by confounding and overestimate the effects of low-level lead exposure.

Aquatic plants are used to give the freshwater aquarium a natural appearance, oxygenate the water, absorb ammonia, and provide habitat for fish, especially fry (babies) and for invertebrates. Some aquarium fish and invertebrates also eat live plants. Hobbyists use aquatic plants for aquascaping, of several aesthetic styles.
The Food and Drug Administration followed up with a warning against 17 ground cinnamon products found to contain high levels of lead. Short-term exposure to very low levels of lead may not result ...
Additionally, the regulation lowers the action level of lead contamination to 10ppb from the current limit of 15ppb. [62] [63] Other incidents of widespread lead contamination include the Pittsburgh water crisis (started in 2014, discovered in 2016, ongoing in 2018) [64] and the Newark water crisis (in schools, 2016–2019).

The district's standard of 5 ppb is more strict compared to the state and federal guidelines of 15 ppb, which the U.S. Environmental Protection Agency set as the action level for lead in drinking ...
A 24 ounce Owala was tested by Lead Safe Mama in 2022 and deemed lead-free. S'well There's no indication of lead use in the manufacturing of S'well bottles on its website.
The lead levels required WASA to conduct a wider survey of their water quality. By the fall of 2003, it had tested more than 6,000 homes in the District, finding that two-thirds tested had more than 15 ppb of lead in their water. [3] The survey showed that over 4,000 homes served by WASA had lead levels exceeding the acceptable level. [7]
