Limestone is a naturally occurring mineral complex that contains varying quantities of quartz (crystalline silica). In its natural bulk state, limestone is not a known health hazard. Limestone may be subject to various natural or mechanical forces that produce small particles (dust) which may contain

acid rain acid rain Effects on humanmade structures: Acid deposition also affects humanmade structures. The most notable effects occur on marble and limestone, which are common building materials found in many historic structures, monuments, and gravestones. Sulfur dioxide, an acid rain precursor, can react directly with limestone in the presence of water to form gypsum, which eventually ...

Limestone dust: Immediately flush with plenty of water for at least 15 minutes. Hold eyelids apart. Occasionally lift the eyelid(s) to ensure thorough rinsing. Beyond flushing, do not attempt to remove material from the eye(s). Get medical attention if irritation develops or persists. Limestone dust: Rinse mouth and drink plenty of water.
Water reacts with many substances, including but not limited to alkali metals, hydrides, strong halogenating agents, and chlorosilanes. These reactions can be hazardous and may result in flammable or toxic gas production, or generation of excessive heat that may cause pressurization to occur. Another reactive hazard is heat of mixing.

Systematic experiments were done to examine the effect of pH on surfactant retention and the geochemical reactions in limestone by adding ammonia and sodium hydroxide to the chemical solutions. The addition of alkali significantly reduced the surfactant retention from mg/grock without using alkali to mg/grock using wt% ammonia to mg/grock using wt% sodium .
