What is the problem?

Chemicals are all around us in the form of the objects we touch, the air we breathe, the products we use, and the food and liquids we consume.

Some chemicals are of concern because of the negative health impacts they have, such as lead, arsenic, and other naturally-occurring heavy metals on cognitive function and behaviour.

These are especially concerning when exposures occur at sensitive periods of development, such as during pregnancy or in childhood.

What have we found?

• We are routinely exposed to a wide range of environmental chemicals from foetal life through adulthood
• Exposure to heavy metals and chemicals can negatively impact on behaviour, blood pressure, respiratory health, and liver function in children
• Some chemicals found in foods, or formed when foods are cooked, can have harmful effects for our health
• Individuals can lower their exposure to some chemicals by swapping out plastic food storage containers and choosing alternative personal care products

What has changed as a result?

Our findings have helped increase our understanding of how our everyday exposures can impact on our health and the health of our children.

This has prompted a human study to understand whether feasible and effective interventions can be created to reduce our exposures to chemicals found in our cosmetics and personal care products.

Our work has also contributed to national, international, and US changes in guidelines to reduce exposures to acrylamide.
