This spike has been attributed to occupational exposure (often by tradies) to socalled engineered or artificial stone products often used for kitchen benchtops.

grinders, and highspeed polishers, have some of the highest silica dust exposures in the countertop manufacturing, finishing and installation industries. These exposures come from dry cutting, grinding, edging, and contouring stone, and may occur in shop environments as well as on job sites where finishing work is completed.
Silica is found in both natural and manmade substances. It is existent in three types: quartz (most common), cristobalite and tridymite. Materials including sand, concrete, brick, concrete block, stone, sheet rock, tile, grout and mortar all contain one of the above types of crystalline silica.
Engineered stone is 93% quartz based on weight; the rest is a mix of resin, glass, dyes ect. It starts off as a powdered mix and is pressed into slabs. While there are several brand names of engineered stone on the market today, most are generally made using the Breton machinery.
Because of workexposure to silica dust, silicosis is an occupational hazard to mining, sandblasting, quarry, ceramics and foundry workers, as well as grinders, stone cutters, stone countertops, refractory brick workers, tombstone workers, workers in the oil and gas industry, pottery workers, fiberglass manufacturing, glass manufacturing, flint .
These cleaning tips for quartz, travertine, porcelain, engineered stone, granite, marble, and soapstone (and even butcherblock) will help keep your countertops looking spotless You've invested in your kitchen, bath or whole house remodel.
Silica is expressed as a mass concentration of the contents of a total dust sample. To determine the silica content of an aerosol, a sample is weighed and analyzed by a lab to determine what amount of silica is present. If the sample only contains respirable dust, than the silica contained within is respirable silica.
Share A Beginner's Guide to OSHA's Final Silica Rule. Author: John F. Martin (Washington DC) Published Date: April 4, 2016 On March 24, 2016, the Occupational Safety and Health Administration (OSHA) announced its final rule on occupational exposure to respirable crystalline rule was published in the Federal Register .
Yet, silica dust hazards are real for masons who craft natural or engineered stone countertops. In fact, OSHA and NIOSH recently released a Hazard Alert on worker exposure to silica during countertop manufacturing, finishing and installation .

Common construction material containing silica includes: Concrete, including readymix concrete; Stone products; Bricks; Structural clay; Glass products; Certain types of paint and coatings . When these products are drilled, crushed, cut or abraded, they release silica dust in the air.
Studies have reported reductions in the range of 60% to 86% for respirable silica and dust in various applications including stone crushing, construction, mining, and manufacturing industries. Health Effects of Crystalline Silica
does engineering stone have silica. Flotation Machine With the development of mining industry, investors present various requirements of the features of flotation machine.
To prevent the engineered stone from these weathering deteriorations, the silica sand and aggregates were carefully washed producing salt free mixtures, and all mixtures were vibrated during casting to reduce voids in the stone.
