Exposures occur to a limited extent in horticultural uses and in other occupations.
The general public may be exposed to the particulates emitted from chimneys when domestic heating fuels are burned. 5.2 Experimental data Coal soot was tested in two experiments in mice by whole-body exposure, but the studies were inadequate for evaluation. Coal-soot extracts applied to the skin of mice produced skin tumours in two studies. A wood-soot extract applied to the skin of mice was inadequately tested. An extract of fuel-oil soot was inadequately tested by application to the skin of mice.
