Are these 6 Common Environmental Hazards Hiding in Your Early Learning Classroom?

Did you know that many common items found in day care and early learning classrooms can pose environmental hazards to the children in your care? These pesky, dangerous hazards hide in plain sight and are found in some of the most common everyday products.

Products containing chemicals and heavy metals linked to childhood asthma, learning disabilities, and increased risk of cancer are found in classrooms worldwide. Luckily, you can help prevent harmful environmental exposures by identifying potential hazards in your classroom!


Peeling paint on window sillLead exposure, even in small amounts, is now known to affect children’s brain development resulting in reduced intelligence quotient (IQ), behavior changes such as reduced attention span and increased antisocial behavior, and reduced educational attainment. Lead exposure also causes anaemia, hypertension, renal impairment, immunotoxicity and toxicity to the reproductive organs.

Unfortunately, lead can be found in many homes and daycares due to the previous widespread us of lead paint. Lead paint could be present on walls and doors, as well as on toys and ceramic dish ware. Carpets and other fabrics can collect lead dust and chips over time and become highly concentrated sources of lead exposure.

Household Cleaners

Irritated eyes and skin, asthma, allergies, and the risk for poisoning when consumed are all health risks associated with common household cleaners. A growing number of scientists also claim that certain chemicals, including organophosphates and phthalates, are likely linked to brain damage and hormone disruption.

Plastic Products

Brominated fire retardants, phthalates, and BPA are among the most commonly found toxic chemicals. These chemicals have been linked to disrupted hormone systems, endocrine disruption, and effects on the brain and behavior.

Exposure to mold produces an array of symptoms, with respiratory issues being the most common. Children can experience congestion, sore/itchy throat, coughing, shortness of breath, wheezing, and increased risk of asthma. More serious symptoms of prolonged exposure to toxic molds include circulatory symptoms, vascular problems, and neurological symptoms.

Art Supplies

Lead, asbestos and organic solvents are sometimes used in common art supplies. These toxic ingredients can trigger asthma, allergies, headaches and nausea, especially if used in a poorly ventilated area. While children may not necessary be exposed to harmful substances when using art products properly, ingestion, inhalation, and skin contact can lead to serious health effects.

All of these potential hazards may sound scary and overwhelming, but there are many free to low-cost steps that can be taken to reduce and eliminate common environmental hazards in child cares.

Here are 5 easy steps you can take today to reduce the environmental hazards in your classroom:

1. Choose eco-friendly, green cleaning products

2. Remove old carpets or other fabric products from the classroom

3. Provide close supervision and open the windows during art projects

4. Ensure that children wash hands with soap and water immediately after art projects

5. Reduce the need for chemical pesticides by storing food and drinks in tight containers, keeping surfaces clean and dry, and removing trash and compost regularly
