Airborne Lead and Hillsboro Airport The Impact on our health and what can be done The Hillsboro Airport is the single largest The Center for Disease Control and Prevention industrial emitter of airborne lead in Oregon. (CDC) warns that "children are more vulnerable This was reported by Environmental Protection to lead poisoning than adults... Even at much Agency (EPA) 2014 National Emissions lower levels of exposure, lead can affect a child's Inventory (NEI) released in February 2018, the mental and physical growth... Exposure to lead is most recent year that NEI data is available. more dangerous for young and unborn children. According to the EPA, the Hillsboro Airport Unborn children can be exposed to lead through releases 1,211 pounds of lead annually into the their mothers. Harmful effects include premature air at 3355 NE Cornell Road in Hillsboro. births, smaller babies, decreased mental ability in the infant, learning difficulties, To put airborne lead pollution and reduced growth in young from Hillsboro Airport in children." perspective, of all the foundries, lead smelters, steel The US Department of Health mills, battery manufacturers, and Human Services Public airports, mines, chemical Health Statement reports lead plants, and military bases in exposure is caused by either the United States, Hillsboro breathing in lead or swallowing Airport ranks 65th worst out it. According to the ATSDR, of 35,804 sources of airborne shortly after lead enters the industrial lead pollution body: "... it travels in the blood watched by the EPA. to the ‘soft tissues’ and organs AIRPORT (such as the liver, kidneys, Lead, whether inhaled or lungs, brain, spleen, muscles, ingested, is dangerous.

The CDC published laboratory 1,500 feet from an airport that used avgas had reported blood lead levels from 1987 to 2013 blood lead levels 2.1% higher than children who using data from 41 states. The CDC concluded didn't live by an airport. Kids living within 500 "evidence indicates that lead exposure at low meters of an airport where avgas is used had doses can lead to adverse cardiovascular and blood lead levels 4.4% higher than kids living kidney effects, cognitive dysfunction, and away from an airport. adverse reproductive outcomes." According to research Due to the danger to human published by the Natural health, lead was phased out Resources Defense Council, "At of automotive gas in the US least 3,200 students who attend beginning in 1973.

Emissions during into the air on flights over the community and local flying are more likely to influence air and consequently can be inhaled or ingested. soil concentrations of lead in the vicinity of the airport because they occur near the airport." It is not just workers at lead mines and battery factories who risk getting dangerous levels of Each year there are three times as many "local" lead into their blood. A 2011 study of blood lead flights at the Hillsboro Airport as there are flights levels of 125,197 children, including 13,478 used for transportation according to Federal children living near airports, indicates that Aviation Administration (FAA) records. It is the "living within 1,000 meters of an airport where local flights - those that are not being used for avgas is used may have a significant effect on transportation - using small aircraft fueled by blood lead levels in children." The three avgas. Airborne lead pollution from airports is researchers Miranda, Anthopolos, and Hastings, preventable — it is not caused by commercial whose study was published in Environmental passenger or freight flights. Hillsboro Airport's unusual problem with lead is largely due to Of the 134 airplanes using 100LL leaded avgas at discretionary flight training and recreation Hillsboro Aero Academy, 111 could switch to flights using small piston-engine planes and UL94 Unleaded Avgas according to FAA helicopters. These small aircraft are using avgas Registry data. Of those eligible to use unleaded which contains amounts of lead similar to the avgas, 84 can use it immediately with no leaded gas used in cars back in the 1970s. additional paperwork required; 27 of their planes require a Supplemental Type Certificate, For example, Hillsboro available through a quick Aero Academy flies more and easy application. than 68,000 miles per year with most flights just Lead pollution from circling the Hillsboro commercial use of small airport.
