Burns also discussed the trend in respirable crystalline silica data, after July 2020 saw a modification to the exposure standard, limiting the acceptable level of silica dust in the air to 0.05mg per cubic metre. An expected jump in exceedances by quarries was seen after the reduction took hold, but not as much as may have been expected.

Silicon dioxide (SiO2), commonly known as silica, is a mineral that constitutes 59% of the Earth's crust by mass. It can be found in various natural sources such as soil, sand, granite, and concrete, and over 95% of known rock types on our planet. Silica exists in two primary forms: crystalline and non-crystalline, also known as amorphous.
