Respirable
Suspended Particulates
RSP are the
proportion of total suspended particulates
of a size smaller than 10 micrometres and they have the ability
to penetrate deeply into the lungs. Depending on their source and
the existing meteorological conditions, RSP can be made up of a
number of different constituents.
Particulates
constituents
There are a
number of chemicals that may form part of RSP. Two important constituents
are lead and aromatic hydrocarbons.
A number of constituents of RSP and their sources are given in the
table below.
