Answers
Answer:
Inorganic acids are of prime importance in the chemical and metal industries.
They are used as raw materials in the manufacture of a wide range of chemicals,
as well as in refining, electrolysis and extraction in chemical processes. Inorganic
acids are widely used in the pickling processes of electroplating, in vehicle
production plants and in steel producing plants.
The present document concerns the effects of four inorganic acids: sulphuric
acid (H2SO4), hydrochloric acid (HCl), nitric acid (HNO3) and phosphoric acid
(H3PO4). It does not consider sulphur dioxide, nitrous gases, or phosphorous
compounds such as phosphorous pentoxide and red phosphorus, which may be
converted to phosphoric acid.
A previous NEG document published in 1993 described the effects of aerosols
of these four acids (142). The biological effects of H2SO4 are relatively well
investigated, whereas the documentation concerning the effects of the other three
acids, discussed in this document, is limited.
Acid concentrations are given in mg/m3
. Data originally reported in units of
ppm have been converted to units of mg/m3
by using the conversion factors given
in Table 2. Occasionally, the originally reported ppm values are also given.
