Pathways of Exposure at the Hunters Point Naval Shipyard — view from an unfortified chain metal fence line separating a neighborhood with the cities largest childhood population from the radiation and chemical contaminated regions of the southern shoreline.
Interactions and passage of heavy metals between the maternal circulation and the fetus through the placenta. The placenta acts as a filter to block the passage of harmful chemicals to protect the fetus from exposure to pollutants. The placental barrier is not impermeable and heavy metals have been detected in placental tissues, amniotic fluid and umbilical cord blood.

Mass spec is an analytic technique in which atoms or molecules are ionized using a high energy electron beam and then separated based on their mass to charge ratios. The results are presented as a mass spectrum which shows the relative abundances of the ions on the y-axis and their m/z ratios on the x-axis. Calculating the exact mass of multiple molecules in a sample allows scientist to precisely identify each one. This is called aggregate analysis.

The Hunters Point Naval Shipyard ranks at the top of the National Priorities List of contaminated federal Superfund sites following decades of commercial and industrial use as “The world’s greatest shipping yard.” In 1946 the United States Naval Radiological Defense Laboratories established a radiation research campus on the southern shore of the shipyard that includes a 46 acre industrial landfill. The southern shoreline drains into the South Basin of San Francisco Bay and travels westward in a channel of water called Yosemite Slough that extends within half a mile from a residential neighborhood, Bayview Park, MLK swimming pool, the Southeast Health Center and a high volume McDonalds fast food restaurant.
The Historical Radiological Assessment Volume II details GRAM use at the Hunters Point Shipyard. The final HRA was published in August of 2004. The transfer of shipyard Parcel A began in January of 2004 when the Chronicle reports speaker Nancy Pelosi “strong armed’ the transfer of the property over concerns by military leaders that it was too radiation contaminated for residential development.
The Genova Diagnostics Comprehensive Urine Elements Profile screening is a low cost, simple to process test kit that can be easily collected at the point of community or occupational exposure. It is capable of detecting 35 toxic and nutrient elements with a 10 day turn around upon receipt of the biologic sample shipped by FedEx delivery.

Uranium was detected in a concentration almost double the maximum allowable for the reference concentration:

Demolition, remediation, excavation and development on a contaminated federal Superfund site complicated by radioactive soil fraud exposes a nearby community to toxic metals and radioactive elements that are being detected by the Hunters Point Community Biomonitoring Program. Manganese and vanadium have been detected universally in urinary screenings conducted on residents and workers within a one mile buffer zone.
Hope and “Faith/Black survivors of breast cancer share inspirational stories in Bayview Calendar. The Bayview Imani Breast Cancer Support Group emerged in 1999. A 2002 calendar featuring photos and stories of 24 breast cancer survivors is called “Faith” Margie is Ms. June.

Deep soil excavations on a federal Superfund site at the fence line on the Hunters Point hilltop.
Serpentine soils contain high concentrations of heavy metals including chromium, iron, cobalt and nickel along with the fibrous mineral chrysotile asbestos. More importantly the excavation of tons of serpentinite rock beginning in 2006 and resumed in June of 2020 generates fine particulates linked to a spectrum of cardiopulmonary diseases and increased infant mortality rates.

The unfortified fence line separating the radiation contaminated southern shoreline of the Hunters Point Shipyard from a residential community 0.5 miles west. The building in the backdrop is the radiation contaminated enlisted men’s quarters.
View of Building 815 situated on Crisp Road at its juncture with the heavily contaminated southern shoreline. This photo is taken from a simple chain metal fence separating dense residential neighborhoods, parks, playgrounds and other sensitive receptors to the west from the shipyards southwestern panhandle region.
Revere Avenue at Ingalls Street is within 500 feet of the radiation contaminated southern shoreline of the Hunters Point Naval Shipyard and the Parcel E-2 landfill — federal Superfund properties.
Building 815 is the windowless iconic historical remnant of NRDL operations from 1946–1969. The six story building contained laboratories and administrative offices. The Atomic Energy Commission allowed NRDL scientists to pour effluents of radioactive waste into laboratory drains and to dump radioactive objects and irradiated animal carcasses into a 46 acre industrial landfill called Parcel E-2 on the shoreline. On a hot day in August 2000 the landfill erupted into multicolored flames and was not fully extinguished for months. An ATSDR report concluded volatile organic compounds including benzene and elevated levels of manganese were detected in air monitoring conducted over 30 days after the landfill fire erupted.
Fence line at Revere Avenue east of Ingalls Street separating the radiation contaminated Parcel E-2 shoreline and industrial landfill from residences within 500 feet according to Google maps. There are no dust barriers and the dangerous shoreline can be easily accessed by the public via breaks in the chain metal fence line at the north shore of Yosemite Slough.
The heavily contaminated southern shoreline of the Hunters Point Naval Shipyard drains into the South Basin and travels west toward the residential neighborhood via a horizontal channel of water called Yosemite Slough. In 2016 it was designated a federal Superfund site by the EPA. The subject of this case report lived in three locations less than a mile from this shoreline from 1990 to 2006.

The chemical and radiation contaminated shoreline is designated Parcel E-2 and includes an industrial landfill. Gilman playground marks Gilman Avenue where our subject lived with her oldest child for four years.
US Navy Remediation Document Parcel F Feasibility Study documents extent of radiation contamination of the southern shoreline.
Traffic proximity and lead based paint exposure are determined to be major environmental impacts using the EPA EJScreen.
Urinary toxic exposure screening conducted on 12 year old special needs child with global developmental delays, allergic asthma and environmental sensitivities. Note the match in profile elements detected in mother and son. Arsenic is detected in both in concentrations of 30 ug/g [50 ug/g is TMPL]. Cesium, rubidium and thallium and copper are detected in high normal concentrations while tin, tungsten, manganese and vanadium are toxic. Uranium is detected in a concentration five times higher than maximum allowable levels and manganese exceeds the upper limit of the reference range.
Breast milk can transfer harmful chemicals but is still the healthiest food source for infants.
Cai and Wang found a reduced offspring body weight and survival rate in offspring of female mice exposed by airway or oral routes to nanoparticles of heavy metals.
“ We’ve also found that looking at neurodevelopmental screening in the first year of life, is that these children have slower development in many of the domains that are tested, and they see this really at 10 months of age is where it’s pretty obvious. Another concern is that there seems to be an increase in autism spectrum disorder.” Doctor Discusses Research Showing High Levels Of Uranium in Navajo Women and Babies
Laboratory experiments indicate swaddled babies sleep more, have reduced levels of motor activity in response to stimulation, fewer startles and lower heart rate variability. Reports are reported on an ethological study of cradleboard use among Navajo Indians.

  1. Was the child directly exposed to radioactive metals resulting in a body burden higher than the mothers?
  2. Was the child exposed via the intrauterine route to radioactive metals that bioaccumulated resulting in a body burden of uranium higher than the mothers and five times higher than allowable for the reference population?
  3. Was the child exposed during lactation to radioactive metals that bioaccumulated in the mother during a year of prolonged exposure?
  4. Is the finding of uranium levels five times higher than reference range in a child with growth retardation and global developmental delays born three years after the mother relocated out of the contaminated region, the cumulative impacts of prolonged maternal/child transmission due to both intrauterine exposure and breastfeeding?
