<strong>Summary:</strong> A comprehensive review published in The Lancet states that exposure to plastic chemicals during childhood can cause lasting damage to the heart, reproductive, respiratory, and nervous systems, significantly increasing the risk of chronic diseases later in life.</p>

<h2>Overview of the Research</h2>

<p>On September 21, 2025, the journal <em>The Lancet Child & Adolescent Health</em> published a sweeping review from NYU Langone Health. The study synthesized hundreds of recent scientific findings to systematically assess the long-term health effects of early-life exposure to common plastic chemicals.</p>

<h2>Key Health Risks Identified</h2>

<p>The report pinpointed three major classes of chemicals found abundantly in plastic products as the primary sources of risk:</p>

<ul>

    <li><strong>Phthalates:</strong> Used to make plastics soft and flexible, found in toys, food packaging, and vinyl flooring.</li>

    <li><strong>Bisphenols (like BPA):</strong> Used to make plastics hard and clear, found in water bottles, food can linings, and receipts.</li>

    <li><strong>Per- and polyfluoroalkyl substances (PFAS):</strong> Used for heat resistance and to repel water and grease, found in non-stick cookware, food packaging, and stain-resistant fabrics.</li>

</ul>

<p>These chemicals can leach from everyday items like food packaging, cosmetics, and receipts and be ingested by the body. The research shows they can <strong>disrupt hormonal function</strong>, trigger <strong>body-wide chronic inflammation</strong>, and impair <strong>brain development</strong>. The health problems linked to exposure include:</p>

<ul>

    <li>Heart Disease</li>

    <li>Obesity</li>

    <li>Infertility</li>

    <li>Asthma</li>

    <li>IQ Loss, Autism, and Attention-Deficit/Hyperactivity Disorder (ADHD)</li>

</ul>

<h2>Expert Recommendations for Prevention</h2>

<p>The study's lead author, pediatrician Dr. Leonardo Trasande, offered practical steps for families to reduce plastic exposure:</p>

<ul>

    <li><strong>Swap Containers:</strong> Replace plastic food containers and water bottles with alternatives made of glass or stainless steel whenever possible.</li>

    <li><strong>Avoid Heating:</strong> Never microwave food in plastic containers and avoid putting plasticware in the dishwasher, as heat accelerates chemical leaching.</li>

</ul>

<p>On a policy level, the researchers call for stricter regulations to reduce non-essential plastic use, particularly in low-income communities that often face greater exposure and health disparities.</p>

<h2>Context and Significance</h2>

<p>This review provides robust scientific evidence for the ongoing United Nations' Global Plastics Treaty negotiations, highlighting that plastic pollution control is not just an environmental issue but an urgent public health crisis for future generations.</p>

<p>The authors note that plastic remains essential in specific medical contexts (e.g., ventilators, nebulizers). The study challenges unnecessary plastic use in daily life, not its critical role in healthcare.</p>
