Historical timeline human biomonitoring in the U.S. — the 1993 NHEXAS research opened the door to a modern era of human biomonitoring for an aggregate of chemicals being detected by the Hunters Point Community Biomonitoring Program in 2021

The National Research Council 1991 report, Human Exposure Assessment for Airborne Pollutants concludes “monitoring the environment by identifying and measuring concentrations of chemicals in media (e.g. air, water and soil )is not -by itself- an adequate basis for assessing human exposures. HBM offers an improved understanding of potential health risks through the detection of “biomarkers” of exposure that indicate the progressive response to exposures in the human body that lead to disease… before disease occurs.”

The Radium Girls…they paid with their lives…their fight was for justice!

Pierre & Marie Curie — their remains are so radioactive they are interred in one inch thick lead coffins to prevent radium 226 exposures from harming visitors to the Pantheon.
Amelia “Mollie” Maggia and The Radium Girls — the exhumed bodies of factory workers exposed to radium glowed in their coffins.
Gamma scanning conducted by the California Department of Public Health detected over 200 above background gamma emitting soil anomalies on Parcel A of the Hunters Point Naval Shipyard.
EJSCREEN: Environmental Justice Screening and Mapping Tool/US EPA
EJSCREEN mapping of air toxics cancer risk identifies Bayview district risks in the 87th to 100th percentile. The Hunters Point Shipyard is off line to mapping but the EJSCREEN Standard Report identifies an 87th percentile ranking for NATA cancer risk for the federal Superfund site and neighboring Yosemite Slough.
EJSCREEN Standard Report for the Hunters Point Naval Shipyard and South Basin Region. The majority of variables exceed the 90th percentile for the US population.
HP Biomonitoring conducted a urinary screening on a doctor diagnosed with multiple brain, lung and auditory nerve tumors mapped in the South Basin Cluster. Arsenic, gadolinium and manganese are detected in toxic levels. Rubidium, thallium and copper are detected in high normal to potentially toxic concentrations.

Bar graph comparisons of emergency department visits and hospitalizations shows the disproportional impacts the 94124 zip code faces for a range of cardiopulmonary diseases linked to air pollution that include congestive heart failure, adult and childhood asthma, COPD and pneumonia.
EJSCREEN mapping of fine particulate exposure documents the entire southeast region to be blanked in PM 2.5 in the 90th percentile of exposure compared to the US population.
Hunters Point Shipyard hilltop homeowner for 20 years underwent urinary screening during an asthma attack triggered when she “sees dust” in her environment. Soil elements documented to be present in Parcel A soils are detected in high normal to toxic concentrations including cadmium, cesium, nickel, rubidium, thallium, tungsten, copper, lithium, manganese, vanadium, zinc and potassium.
All elements detected on urinary screening of a hilltop resident during an asthma attack are listed by the EPA or HRA as chemicals or radionuclides used at the shipyard except tungsten and lithium. Tungsten is used in heavy metal alloys such as high speed steel from which cutting tools are manufactured. Tungsten is also used in superalloys to for wear wear resistant coatings. Lithium is an element present in trace amount in virtually all rocks and it’s detection in a urinary screening conducted on a resident who is not prescribed lithium salts for psychiatric illness is proof of exposure to airborne soil elements.

.Solid Waste Disposal Area or SWDA on Treasure Island is an acronym for a military burn pit. The VA Airborne Hazards and Open Burn Pit Registry describes symptoms of exposure that are the same as the TI resident reported when seeking biomonitoring evaluation and screening.

At least two Solid Waste Disposal Areas are located on Treasure Island. One was an incinerator located on the eastern perimeter of the island. In 2019 4,000 cubic yards of toxic soil was excavated from the Northpoint SWDA. The most dangerous region of the island is Halyburton Court designated a SWDA by the Navy and fenced off from the remainder of the island.

Bouagnon is a second year UCSF medical student and scientist with a PhD who assisted the launch of HP Biomonitoring. Dr. Bouagnon was introduced by Arieann Harrison — daughter and scion of Marie Harrison — Mother of the Environmental Justice Movement in Bayview Hunters Point
