Natural sand has eroded from mountain rock and is mined from where it was deposited. The host rock determines the exact mineral composition, but most sand is composed of silica from broken down quartz crystals. This type of sand is extremely resistant to weathering and breakdown due to its chemical hardness and will last longer as arena footing.
toxic materials (e.g., lead paint, silica) that are hazardous to workers. • Silica sand (crystalline) can cause silicosis, lung cancer, and breathing problems in exposed workers. • Coal slag and garnet sand may cause lung damage similar to silica sand (based on preliminary animal testing). • Copper slag, nickel slag, and glass (crushed
