US EPA Test method 12 or a lab can also obtain results from Method 29.
No lead (which would be harmful to you), but some air conditioners emit small quantities of eco-destructive CO2, which the EPA has limited the distribution of in the last 10 or 15 years.
The EPA is the name of the federal agency responsible for monitoring air quality. EPA stands for the Environmental Protection Agency.
Environmental Protection Agency (EPA)EPA
The purpose of the EPA is to protect the land, water and air of the country, to keep them clean and healthy for the people and the natural environment.
Method of transportation
The EPA phased out the use of leaded gasoline primarily due to the severe health risks associated with lead exposure, particularly in children, including developmental and cognitive impairments. Leaded gasoline was also a significant contributor to air pollution, which posed environmental and public health hazards. The phase-out, initiated in the 1970s and completed by 1996, significantly reduced lead levels in the environment, leading to improved air quality and public health outcomes.

In the area of air quality: (1) More than half of the large cities now meet air-quality standards; (2) emissions of common air pollutants have dropped by an average of 24 percent; and (3) blood lead levels in children have declined by 75 percent.
400 mg lead in each kilogram of soil.
Reduction or Elimination of waste
The uranium-lead method is a radiometric dating technique used to determine the age of rocks and minerals. It relies on the radioactive decay of uranium isotopes to lead isotopes in minerals. By measuring the ratio of uranium to lead in a sample, scientists can calculate the age of the sample.
