What does the PCBs stand for and what is it?
PCBs stand for polychlorinated biphenyls, which are a group of man-made chemicals that were used in various industrial applications such as insulating fluids and in sealants. PCBs are now banned in many countries due to their toxic effects on human health and the environment.
How many people are affected by PCBs in America?
Everyone is affected by PCBs, in the US and otherwise. PCBs are most commonly stored in the fat of large fish, so anyone who has consumed fish has probably consumed at least minute quantities of PCBs.
What type of oil is in old ignition coils?
They would contain transformer oil if they have an oil filling. Old transformer oil (made before 1979) included PCBs as a fire retardent. PCBs have been found to cause many health problems including cancers and are now banned from transformer oils.
Why are PCBs - polychlorinated biphenyls - dangerous?
Polychlorinated biphenyls (PCBs) are a class of organic compounds with 1 to 10 chlorine atoms attached to biphenyl which is a molecule composed of two benzene rings each containing six carbon atoms. The chemical formula for all PCBs is C12H10-xClx. PCBs were used as coolants and insulating fluids for transformers and capacitors, stabilizing additives in flexible PVC coatings of electrical wiring and electronic components, pesticide extenders, cutting oils, flame retardants, hydraulic fluids, sealants (used in caulking, etc), adhesives, wood floor finishes,[1] paints, de-dusting agents, and in carbonless copy paper.[2] PCB production was banned in the 1970s due to the high toxicity of most PCB congeners and mixtures. PCBs are classified as persistent organic pollutants which bioaccumulate in animals.
How America recovers ozone hole?
America is trying to recover ozone hole. CFC's have been banned there.
Are PCBs poisonous?
PCBs have serious poisons which have been shown to cause damage to the reproductive, neurological and immune systems of wildlife and humans and are known to cause cancer so yes they are poisonous.
Has Barney been banned?
it has not been "banned".
Why was color purple banned?
Banned from what? To my knowledge, it hasn't been banned, and has been on TV.
Why is calling pcb?
Printed circuit boards (PCBs) are the boards that are used as the base in most electronics – both as a physical support piece and as the wiring area for the surface-mounted and socketed components. PCBs are most commonly made out of fiberglass, composite epoxy, or another composite material.Most PCBs for simple electronics are simple and composed of only a single layer. More sophisticated hardware such as computer graphics cards or motherboards can have multiple layers, sometimes up to twelve.There are several overall types of PCB boards each with their own particular manufacturing specifications, material types, and usages: Single-layer PCBs, Double-layer PCBs, Multi-layer PCBs, Rigid PCBs, Flexible PCBs, Rigid-Flex PCBs, High-frequency PCBs, Aluminum-backed PCBs.
Does anyone import the Norinco JW-15 rifle?
No, not into America, it's been banned from import to punish the Chinese.
Why was The Bible banned in America?
The Bible was never completely banned in America. However, there have been instances of certain translations or versions of the Bible being challenged or restricted due to concerns about separation of church and state or controversy over specific content.
What are the effects of exposure to PCBs?
Exposure to PCBs can lead to various health effects, including skin conditions, liver damage, and reproductive issues. Long-term exposure has been linked to cancer and impacts on the immune and nervous systems. PCBs are considered a serious environmental hazard due to their persistence and ability to bioaccumulate in the food chain.
