Health Effects of Exposure to HDQ Neutral

The document details the health hazards of HDQ Neutral, a quaternary ammonium compound (QAC) containing DDAC and ADBAC. Acute exposure can cause respiratory damage, skin blistering, and digestive burns, while chronic exposure is linked to asthma in humans and severe reproductive and developmental defects in animals. The report expresses concern over reports that HDQ Neutral is sprayed every 15-30 minutes at the Adelanto ICE detention facility, urging a review of the legality and safety of such practices.

• Acute exposure to HDQ Neutral can lead to various adverse health effects depending on the route of contact: inhalation may cause nasal discomfort, coughing, and respiratory mucosal membrane damage; skin contact can cause redness and blistering; and ingestion can lead to digestive tract burns, nausea, vomiting, and diarrhea.
• Short-term inhalation of ADBAC in mice is associated with severe lung inflammation, irritation, and altered breathing. Additionally, exposure to ADBAC at environmentally-relevant doses may be genotoxic, causing DNA damage in both human and animal cells.
• Chronic exposure to quaternary ammonium compounds (QACs) is associated with asthma in healthcare workers. In animal studies, chronic exposure to the QAC mixture in HDQ Neutral caused reproductive issues including altered female reproductive cycles, difficulty conceiving, lower birthweights, and decreased sperm count and motility in males.
• Exposure to the QAC mixture during pregnancy in rodents is linked to an increase in late-gestational fetal deaths and neural tube defects (NTDs), such as spinal malformations and incomplete facial closure. These NTDs persisted in subsequent pregnancies even after exposure ceased.
• The document highlights concerns regarding the Adelanto ICE detention facility in California, where reports indicate HDQ Neutral is sprayed every 15-30 minutes, potentially exposing detainees—including children and people of reproductive age—to unsafe levels of the chemical.
