Environmental toxins and synthetic chemicals can disrupt thyroid function in multiple ways. These substances may interfere with hormone synthesis, secretion, transport, metabolism, and receptor activity. Common toxins impacting the thyroid include PCBs, dioxins, perchlorate, and heavy metals such as mercury and lead. Such disruptions can lead to conditions like hypothyroidism or hyperthyroidism, which can significantly affect an individual's health and well-being.
