Dioxins are chemical compounds produced by combustion processes involving chlorine. They are found in incineration, manufacturing chlorinated chemicals like PVC, and other chlorine-using processes like paper bleaching. Dioxins can cause reproductive, developmental, and health issues like cancer and interfere with hormones. Animal products are a major source of dioxin exposure for humans. Reducing consumption of fatty animal products and having a balanced diet can help prevent overexposure to dioxins, which are very persistent environmental pollutants.
