SILICA CRYSTALLINE - QUARTZ
WARNING:
For inhalation exposure ONLY: This substance has been classified by the IARC as Group 1:
CARCINOGENIC TO HUMANS
The International Agency for Research on Cancer (IARC) has classified occupational exposures to
respirable
(<5 um) crystalline silica as
being carcinogenic to humans . This classification is based on what IARC considered sufficient evidence from epidemiological studies of
humans for the carcinogenicity of inhaled silica in the forms of quartz and cristobalite. Crystalline silica is also known to cause silicosis, a
non-cancerous lung disease.
Intermittent exposure produces; focal fibrosis, (pneumoconiosis), cough, dyspnoea, liver tumours.
STYRENE
The material may cause skin irritation after prolonged or repeated exposure and may produce a contact dermatitis (nonallergic). This form of
dermatitis is often characterised by skin redness (erythema) and swelling the epidermis. Histologically there may be intercellular oedema of
the spongy layer (spongiosis) and intracellular oedema of the epidermis.
WARNING:
This substance has been classified by the IARC as Group 2B: Possibly Carcinogenic to Humans.

For silica:
The literature on the fate of silica in the environment concerns dissolved silica in the aquatic environment, irrespective of its origin
(man-made or natural), or structure (crystalline or amorphous). Indeed, once released and dissolved into the environment no distinction
can be made between the initial forms of silica. At normal environmental pH, dissolved silica exists exclusively as monosilicic acid
[Si(OH)4]. At pH 9.4 the solubility of amorphous silica is about 120 mg SiO2/l .
