Industry Group Profile - Lead Exposure. Inorganic lead is a malleable, blue-gray, heavy metal that occurs naturally in the Earthâs crust. Lead was one of the first metals used by humans and consequently, the cause of the first recorded occupational disease (lead colic in a 4th century BC metal worker).

Razor burn is a temporary skin irritation caused by shaving. Different people get razor burn for different reasons, but most of the time, it has to do with shaving too closely, too forcefully, or with a dull razor. It is usually identifiable by the itchy red bumps it leaves behind, and in most cases, only lasts for a few days.
Razor bumps are also referred to as razor burns or ingrown hairs. Razor bumps establish usually on the neck, but they can occur in any location that is shaved such as the cheeks, underarms, pubic area, arms and legs. Razor bumps take place frequently in people who have snugly curled or spiral hair strands.
