Banning lead in gas worked. The proof is in our hair (attheu.utah.edu)

Article summary

A study by University of Utah scientists found that lead levels in human hair have decreased significantly since the 1970s, when the Environmental Protection Agency (EPA) began regulating lead in consumer products. The researchers analyzed hair samples from 48 individuals and found that lead levels were 100 times higher before the EPA regulations. The study highlights the importance of environmental regulations in protecting public health. The findings also note that lead rules are being weakened by the Trump administration, which could have negative consequences for public health.

What commenters say

• The reduction of lead in gasoline has led to a significant decrease in lead exposure and associated health problems, including decreased impulsivity and aggression.
• The study's findings underscore the importance of environmental regulations in protecting public health, and weakening these regulations could have negative consequences.
• Coal power is no longer a viable or economical option for energy production, and it should be replaced with cleaner alternatives such as solar, wind, or nuclear power.
• The phase-out of lead in consumer products has had a positive impact on public health, and similar efforts should be made to reduce other environmental pollutants, such as mercury.
• Some argue that the benefits of environmental regulations are outweighed by the economic costs, and that a more balanced approach is needed.
• Others contend that the transition to renewable energy sources is not happening quickly enough, and that more needs to be done to address the environmental and health impacts of fossil fuels.
• There is a need for a nuanced discussion of the trade-offs between different values, such as cost, reliability, and climate impact, in the context of energy production and environmental regulation.
• The use of propaganda and education can be effective in promoting environmental awareness and behavior change, but it must be done in a way that is accurate and nuanced.
