Florida Children’s Environmental Health

Florida Children's Environmental Health

Florida, the only state in the continental United States with a tropical climate zone, is celebrated for its vast, sunny coastline and diverse wetlands, including the famed Everglades. This unique geography supported a booming citrus industry in the early 20th century, and with the addition of ambitious rail and highway projects, stoked both rapid population growth and an ever-growing tourism sector. The 1971 opening of Walt Disney World Resort defined Orlando as the “Theme Park Capital of the World,” and in 2023, Florida welcomed a record 156.9 million out-of-state visitors.

The low-lying peninsula makes the state extraordinarily vulnerable to climate threats, which have become a growing part of life in Florida in recent years. Greening disease and citrus canker have crippled the citrus industry, while major hurricanes in 2017, 2018, 2022, 2023, and 2024 continued to batter the agricultural industry generally. Rising seas and the growing risks of flooding storms have helped push home insurance premiums to the highest in the country, with some major insurers exiting the state entirely.

Toxic algal blooms, fueled by sewage spills and fertilizer runoff, all contribute to water quality and pollution concerns for Floridians, with children being particularly vulnerable. The state’s environmental policy has focused on PFAS contamination in water and soil, including the 2022 passage of HB 1475 which requires the Department of Environmental Protection to adopt statewide rules for cleanup target levels in soil and groundwater by particular dates as well as HB 5001, an appropriations bill with nearly $30 million for testing and remediation for PFAS.

In the profile below, you’ll find a set of key children’s environmental health indicators that illuminate Florida’s environmental risks, children’s exposures, and emerging trends in child health and development.

Children's Environmental Health Indicators Selection Criteria

Each headline indicator should be a clear, understandable indicator of children’s environmental health, with broad relevance for a range of audiences at the state level – with relevance to the national level.

The indicators as a package should provide a representative picture of children’s health and relation to the environment.

Each indicator should be calculated using an agreed-upon (and published) method and accessible and verifiable data.

Each indicator should be calculated regularly (at least biennially), with a short lag between the end of the period and publication of the data.

The available data needed for the indicator must be sufficiently robust, reliable and valid.

Indicators must be comparable across all or very nearly all 50 U.S. states.

Air Pollution

In this profile, counties with “unhealthy” levels of air pollution are those receiving a grade of F for ozone and/or short-term particle pollution (PM2.5), and/or a grade of “Fail” for year-round particle pollution (PM2.5) in the American Lung Association’s 2024 State of the Air report. According to the report, 10.88% of Florida children under age 18 live in counties that received a failing grade for at least one pollutant. This only considers the 35 counties where air quality data is monitored, collected, and sufficient (out of 67).

American Warming

Warming matters — it drives most of the hazards associated with climate change such as extreme weather, heat days, droughts, and heavy downpours. Children are more vulnerable to harm from extreme heat and to the other cascading effects of warming temperatures.

Toxic Release Inventory

EPA’s Toxics Release Inventory (TRI) tracks the management of certain toxic chemicals that may pose a threat to human health and the environment. Certain industrial facilities in the U.S. must report annually how much of each chemical is disposed of or released on- and off-site. Many of these chemicals are known carcinogens, developmental toxicants, and neurotoxicants, such as arsenic, lead, and mercury, that adversely impact children’s health.

Neurodevelopmental Notes

Mounting scientific research links environmental exposures with risk of Attention-Deficit Hyperactivity Disorder (ADHD), Attention-Deficit Disorder (ADD), and Autism Spectrum Disorder (ASD). Neither genetics nor changing diagnoses or other artifacts fully account for the increased incidences of these conditions. ADHD, ADD, and ASD data are for California children aged 3-17 years.

Asthma prevalence

A wealth of research links exposure to poor outdoor air quality, including high concentrations of ground-level ozone, with the exacerbation of children’s respiratory illnesses, including asthma. Several studies link it with the onset of childhood asthma.

Childhood Blood Lead Surveillance Data

According to the Florida Department of Health, 11.04% of Florida children under age 6 were tested for blood lead levels (BLLs) in 2023. Of those tested, 2.89% had a BLL ≥ 3.5 μg/dL. Often the most vulnerable children are not tested, and not all who are tested get reported, so this is likely an underestimate of the true scope of children’s elevated blood lead in Florida. There is no safe level of lead exposure for children. A potent neurotoxicant, lead reduces IQ and impairs other cognitive, behavioral, and developmental functions. In 2021, the CDC lowered the BLL reference value from 5 to 3.5 μg/dL, but much of the available data still categorizes “elevated” BLLs as being 5 ug/dL or higher.

Pediatric Cancer Indicator Notes

Although cancer in children is rare, the rate of pediatric cancer has been increasing since the 1970s. It is the leading disease-related cause of death past infancy in U.S. children. Neither genetics nor improved diagnostic techniques can explain the increased rate.

According to the President’s Cancer Panel’s 2008-2009 Annual Report, “the true burden of environmentally induced cancer has been grossly underestimated.”

All children deserve and need a safe and healthy environment to grow and develop. They need clean air to breathe, safe water to drink, nutritious food to eat, and healthy places in which to live, learn, and play. Early exposure to harmful agents can lead to acute and chronic adverse outcomes. Infants and children are especially vulnerable to environmental exposures because they breathe, eat and drink more, in proportion to their body size, than do adults, and because their bodies and brains are still developing.

A blueprint for Protecting Children’s Environmental Health Network set out to identify a set of CEHIs that can be used to provide an understanding of children’s environmental health at the state level. Through this process, CEHN found that robust, valid, and regularly updated state level data–that are comparable across most states–were not readily accessible. States need adequate funding and capacity to collect and make accessible reliable CEHI data in order to set goals and track progress towards improving children’s health.

Children are our future – society has a moral obligation to protect them. Exposure to environmental hazards can and must be prevented. Prevention requires strong environmental regulations, fully funded and supportive public and environmental health programs and a robust workforce.
