A new analysis of national poison control records, hospital surveillance data, and academic research reveals a fragmented and increasingly strained chemical safety landscape in the United States. The study, compiled by Anidjar & Levine, shows that young children face widespread exposure to hazardous substances in their homes, communities, and even before birth. The findings point to a systemic problem that extends far beyond isolated accidents and reflects gaps in prevention, monitoring, and public awareness.
The scale of the issue is clear in the national numbers. In 2023, U.S. Poison Control centers handled nearly 2.1 million human exposure cases. Forty percent involved children under the age of six. While most exposures were unintentional, the volume and severity of incidents show that current safety systems are not keeping pace with the risks children face in modern environments.
Fatalities Have Risen to Levels Not Seen in More Than Three Decades
Although child chemical fatalities remain far lower than in the 1970s, recent years show a sharp reversal of earlier progress. Fatalities increased from 34 in 2019 to 97 in 2022, before decreasing slightly to 90 in 2023. These numbers represent the highest unintentional chemical fatality rates for children since 1991.
Pediatric Fatalities From Chemical Exposure (2019 to 2023)
- 2019: 34
- 2020: 43
- 2021: 59
- 2022: 97
- 2023: 90
The substances linked to these deaths reveal additional concerns. Analgesics were the leading cause of fatal exposures between 2019 and 2024. Fumes and gases, stimulants and street drugs, batteries, and unidentified drugs also contributed to fatalities. Deaths involving narcotics and psychodysleptics doubled between 2021 and 2023, rising from 33 to 66 cases.
These trends suggest that children are increasingly exposed to substances that were once considered adult‑only risks, including prescription medications and illicit drugs.
Children Carry Dozens of Chemicals in Their Bodies Before Kindergarten
One of the most striking findings in the report comes from a UC Davis Health study that analyzed urine samples from 201 children across four states. Researchers detected 111 chemicals in the samples, including substances from plastics, cosmetics, food packaging, dust, and air pollution.
The study found:
- 96 chemicals detected in at least five children
- 48 chemicals detected in more than half
- 34 chemicals detected in more than 90 percent
Nine of the chemicals detected are not currently tracked in national health surveys, which suggests gaps in federal monitoring systems. The chemicals included phthalates, parabens, bisphenols, benzophenones, pesticides, organophosphate esters, polycyclic aromatic hydrocarbons, and bactericides.
The study also found that unborn children often carried higher levels of certain chemicals than their mothers. These included two phthalates, bisphenol S, and pesticide biomarkers. This indicates that exposure begins before birth and continues through early childhood.
While levels of some chemicals declined over the study period, others, including newer pesticides and plasticizers, increased. Firstborn children had lower chemical levels than younger siblings, and two‑year‑olds often had higher levels than three‑ or four‑year‑olds, likely due to increased hand‑to‑mouth behavior.
Emergency Department Data Shows a Persistent and Growing Burden
Hospital surveillance data from the National Electronic Injury Surveillance System shows that unintentional chemical poisoning among children under five resulted in:
- 62,600 emergency department injuries in 2021
- 68,600 in 2022
- 67,000 in 2023
Across the three years, the average annual total was more than 66,000 injuries. In 2023, 72 percent of incidents occurred in the home. Most children were treated and released, but 13 percent required hospital admission or transfer. Boys accounted for 54 percent of cases.
Age Breakdown of 2023 Emergency Cases
- Under 1 year: 6 percent
- Age 1: 36 percent
- Age 2: 29 percent
- Age 3: 18 percent
- Age 4: 11 percent
These numbers show that the highest risk occurs between ages one and two, when children are mobile but lack awareness of hazards.
Household Products Drive the Majority of Exposures
The top products linked to pediatric poisonings in 2023 were common household medications and cleaners. These included:
- Blood pressure medications: 5,800 cases
- Dietary supplements: 5,200
- Acetaminophen: 4,900
- Bleach: 3,600
- Antidepressants: 2,800
- Ibuprofen: 2,400
- Illegal drugs: 1,900
- ADD medications: 1,800
Laundry detergent packets also appeared frequently, though national estimates were not available. The presence of both prescription medications and everyday cleaning products in the top categories highlights the range of risks inside the home.
Fentanyl Exposure Has Increased at an Alarming Rate
One of the most dramatic trends involves illicit fentanyl. Poison Control centers recorded only 10 cases of fentanyl exposure in children under six in 2016. By 2023, the number had risen to 539, representing a 5,290 percent increase. More than 80 percent of these exposures occurred in the home.
This increase reflects the broader national rise in fentanyl availability and underscores the vulnerability of young children in households where the drug is present.
Geographic Patterns Reveal Uneven Risk Across the Country
Between 2020 and 2025, children under six were involved in 436,444 poison control cases. The states with the highest call volumes were Texas, California, and Florida. The District of Columbia, Vermont, and Rhode Island had the lowest numbers.
These differences reflect population size but also point to regional variations in exposure patterns, product use, and reporting practices.
Ingestion Remains the Dominant Route of Exposure
Between 2020 and 2025, children were exposed to chemicals through:
- Mouth: 3,485 cases
- Mouth and skin: 138
- Eye: 122
- Inhalation: 17
- Injection: 9
- Multiple combined routes: 108
The dominance of ingestion highlights the importance of secure storage and child‑resistant packaging.
A Systemic Problem That Requires Systemic Solutions
The study by Anidjar & Levine concludes that 99 percent of chemical exposures in young children are unintentional. The data suggests that improved product safety standards, stronger monitoring systems, and better household practices could significantly reduce injuries and deaths.
