Extending Regulatory Biokinetic Lead Models towards Food Safety: Evaluation of Consumer Baby Food Contribution to Infant Blood Lead Levels and Variability.

The U.S. Food and Drug Administration released proposed lead (Pb) action levels for foods intended for babies and young children in January 2023 based on the agency's interim reference value of 2.

Evaluation of potential gastrointestinal carcinogenicity associated with the ingestion of asbestos.

The inhalation of asbestos, depending on the fiber type and dose, may be associated with the development of mesothelioma and other asbestos-related diseases. However, little is known about the potential adverse effects associated with the ingestion of asbestos. Evidence of asbestos fibers released from asbestos-cement pipes used in water distribution systems has led to concerns of potentially contaminated drinking water.

Characterization of background concentrations in upper Manhattan, New York apartments for select contaminants identified in World Trade Center dust.

Residential indoor concentration of asbestos, lead, synthetic vitreous fiber (SVF), crystalline silica, calcite, gypsum, dioxin, and polycyclic aromatic hydrocarbons (PAHs) were measured in 25 residences and 9 building-interior common areas in upper Manhattan, NY. This was done to characterize the background levels of contaminants, identified in dust related to the collapse of the World Trade Center towers, at locations that were minimally impacted by the dust fallout. The study was initiated due to the paucity of background concentrations on building-related materials and combustion byproducts in urban residential dwellings.

Evaluation of vacuum and wet-wipe methods for removal of World Trade Center dust from indoor environments.

The destruction of the buildings at the World Trade Center (WTC) complex dispersed dust and debris into the surrounding area. Pulverized building material made up most of the fallout and was intermixed with combustion byproducts of the aircraft and building contents. A study was conducted to confirm the effectiveness of several cleaning procedures in removing WTC-related contamination from lower Manhattan residences.
