The Chemistry of Eggs & Egg Shells

It makes sense to start from the outside of the egg and work our way in, so let’s begin with the egg’s shell. It’s made primarily from calcium carbonate, the chemical compound which also makes up the majority of sea shells, as well as chalk and limestone. Nanoparticles of calcium carbonate are arranged into ordered crystals by proteins, eventually forming the calcite mineral that makes up the shell. The shell isn’t actually completely solid – it has thousands of tiny pores, around 9,000 on average, which allow gases to pass in and out. As we’ll see later, this can have implications for cooking.

WHAT ARE PFAS CHEMICALS? Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that includes PFOA, PFOS and GenX chemicals. Since the 1940s, PFAS have been manufactured and used in a variety of industries around the globe, including in the United States. PFOA and PFOS have been the most extensively produced and studied of these chemicals. Both are very persistent in the environment and in the human body. Exposure to certain PFAS can lead to adverse human health effects.

Working in heat can be hazardous and can cause harm to workers

Infographic | December 18, 2019

You must do everything reasonably practicable to eliminate the risks of working in heat. Where the risk cannot be eliminated, it must be minimised as much as reasonably practicable. Different workers may react differently to heat conditions. 5 Heat is not just a hazard when working outdoors on hot days. Consider the conditions inside your workplace and what hazards may be present.
