🛑 CADMIUM: An Extremely TOXIC and Very USED Metal! Find out why Cadmium is Dangerous! 🛑
🛠️ Speak up, Engineering Lovers! 🛠️
Did you know that while you worry about lead and mercury, you may be ignoring one of the most toxic metals around us? We're talking about Cadmium! This metal, which is found naturally in zinc ores, can be hidden in the foods you consume daily. 🌱🥕 Let's unravel the mysteries behind cadmium and understand why it is so dangerous for our health!
In this video, you will discover:
🔹 What is Cadmium: Learn about its chemical and physical characteristics, such as the symbol Cd, atomic number 48, and its similarity to zinc and mercury. Did you know that cadmium is soft, silvery white with a bluish tinge, and chemically similar to zinc and mercury? Let's explore how it is found in nature and why it is such an intriguing metal.
🔹 Properties of Cadmium: Discover why it is so used in various industries, from batteries to solar energy. Cadmium is ductile, malleable, corrosion resistant and has a low melting point, making it perfect for various industrial applications. Additionally, its ability to absorb neutrons makes it valuable in nuclear reactors.
🔹 History of Discovery: Find out how and when cadmium was discovered by German chemist Friedrich Stromeyer in 1817. Let's go back in time and understand how Stromeyer isolated cadmium from sphalerite, a zinc ore, and the importance of this discovery for chemistry and industry.
🔹 Industrial Applications: Understand how cadmium is used in batteries, pigments, steel coatings and solar cells. Let's explore how nickel-cadmium batteries revolutionized electronics and how cadmium is still crucial in making efficient, low-cost solar cells.
🔹 Where to Find Cadmium: Discover the world's main cadmium deposits, including locations in China, Canada and the United States. We will show how China leads the world in cadmium production, followed by large deposits in Canada and the USA, and the relationship between zinc mining and cadmium extraction.
🔹 Health Impacts: Learn about the dangers of cadmium, how it can cause kidney and respiratory problems, bone damage and even cancer. Prolonged exposure to cadmium can have severe health consequences, including kidney dysfunction, lung disease and cancer risks. Let's discuss how to protect yourself from these risks.
🔹 Cadmium in Food: See how cadmium contamination can reach you through vegetables such as carrots and lettuce. The use of fertilizers and pesticides containing cadmium can result in its presence in the food we consume. Learn how to avoid this unwanted exposure and keep your food safe.
