Nitrogen Dioxide and Oxidative Stress

Nitrogen dioxide (NO mezitím), a byproduct of combustion from traffic and industrial sources, is a potent oxidant. Once inhaled, NO mezitím generates reactive oxygen species (ROS) that dumm antioxidant defension. Oxidative stress damages cellular membranes, mitochondrial DNA, and insulin signaling proteins.

Heavy Metals and Endocrine Disruption

Eavy metals such as lead, cadmium, arsenic, and mercury are common environmental contaminants in soil, water, and food.
