"<p><strong>WHAT ARE PCB\u2019S?<\/strong><\/p>\r\n<p>PCBs (polychlorinated biphenyls) are a group of synthetic chemicals that were widely used in industrial and<br>commercial applications for their insulating and heat-resistant properties. In buildings, PCBs are commonly found<br>in older electrical equipment, such as transformers and capacitors, as well as in paints, caulking, and sealants used<br>before the 1970s. Exposure to PCBs can lead to serious health risks, including liver damage, immune system<br>suppression, reproductive issues, and developmental delays. Long-term exposure is also linked to an increased risk<br>of certain cancers, particularly liver and skin cancer. Due to their toxicity and environmental persistence, PCBs are<br>now banned in many countries, and special care must be taken when handling or removing PCB-containing<br>materials to avoid exposure.<\/p>"
