Introduction
Protecting the environment is one of the issues of today that is receiving
most attention.
Many articles are published in the national and international press to demonstrate
the interest in ecological problems, which are continuously debated among the
authorities, opinion leaders and public figures, as well as by the man in the street.
Pollution is present in all areas of our daily lives: at work, during our free time,
during the day, at night, in our food, drinks and in the environments we act within.
This is a universal problem, affecting the atmosphere and, as a chain reaction,
plant growth, the sea and of course all of the earth’s inhabitants.
One of the most serious forms of pollution, and one most considered in our
cities, concerns atmospheric pollution, found in the air we breathe in every
day. Vehicle exhaust gases, domestic heating, polluting emissions from
industry, all create dust particles that are deposited on the ground together
with other residues, and constitute a serious threat to the health of its
citizens.
The issue that our company has been concentrating on over the years is the
effect of road sweeping on atmospheric pollution, and especially on particulate,
now referred to generically within public opinion as PM10, which causes serious
damage to our health.
Studies carried out in Berlin (Germany) by the DTM were the first to highlight the
devastating effects of road sweeping, done in the German capital using suctiontype machines.
These studies, published by the UBA and carried between 1992 and 1994 with
the aim of maintaining air cleanliness, in fact showed how from an indicative
calculation that the 100 sweepers used daily in the German capital re-emitted into
the air a total of 200,000 kg of dust sucked up from the road surface!!!

Where it comes from…
PUBLIC HEALTH…
EU-Enviromental comisinar Dimas published a study that through the emmisions in
Europe 310.000 human dies. And of it only in Germany 65.000 deadth.

The danger…
The effects on human health
Their danger for health is due to the fact that this fine dust can be inhaled and reach the inner lung, interfering with the
respiratory activity of the bronchioles and pulmonary alveoli.
They often contain many micro pollutants that are very harmful to man, including traces of heavy metals and aromatic
polycyclic hydrocarbons, which can lead to inflammation, fibrosis and cancer.
Results show that mortality rates increase hand in hand with the increase in the number of particulates with a diameter
of less than 2.5 microns: for each “bracket” of 10 micrograms per cubic metre, there is an increase of between 11 and 17
percent in the risk of death from any cause whatsoever . Smaller then 0,1 particular matters goes into our blood.
Particels and where it effects…

EU - Regulations…
Regulations governing the presence of PM in the environment.
The regulation of the European Council Directive no. 1999/30/EC sets limits and, where opportune, alarm
thresholds for the concentrations of sulphur dioxide, nitrogen dioxide, nitric oxide, particulate and lead in the air in
order to avoid, prevent or reduce their harmful effects on human health and more generally on the environment.

The details…
Hístorical regulated dust control:
- Industry (Fixed installations / engines like Step II / Step II)
- Vehicles (a.e. Engines with Euro 2, 3, 4... )
Street Cleaning machines:
- Engines (Euro 3,4 & 5) and dust outlet
There is NOT existing an official regulation for the fine dust
outlet of street cleaning machines, BECAUSE there is no regulation for
a measuring procedure for the emission of these kind of equipment.
Institution / Association that are working on a measuring procedure:
1.
EUnited (private ass. of all manufactures of street cleaning
machines) They started a labelling „PM10 certificated“ based on a
unscientific measuring procedure with the GRIMM
laserspectograph, without taking care of environmental parameters
(wind, street condition, fine dust material on ground)
2.
VDIA (Verein Deutscher Ingieneure).
The question now ….
What will be swept and effectively filtered?

The details…
How does the SUCTION MACHINE filter the fine dust?
Sieve filter of a suction machine for recycling to filter
the fine dust through the water.
What's wrong with this?
This method does not consider the great use of water, which
is in itself becoming a precious resource, nor the re-emission
into the atmosphere of all those PM10 fractions particles
which, being so small, are not weighed down by the water.
It is precisely for this reason that the fine dust particles
collected from the road surface are returned into the
atmosphere at very high speeds and cause an increase in
the PM10 levels measured by the control units.

First row shows the actual capacity of the considered machines during work, rather than the nominal capacity.
Second row shows the PM10 fraction particulate material (from PM0 to PM10) in micrograms measured per cubic metre
given off by the suction turbine(s).
Third row shows the micrograms of particulate material multiplied by the machine capacity in cubic metres, obtaining a
result of grams of PM10 fraction dust emitted in one hour of machine operation.
Fourth row shows the grams of PM10 fraction given off by the machine in one hour of operation multiplied by the average
number of hours swept in one year, consequently giving the Kg of dust re-emitted into the atmosphere over a period of
365 days.
Fifth column compares the emissions of PM of a vehicle with more than 3.5 tonnes, Euro 4 engine in an urban cycle
(average speed 20 Km/h) with the PM emissions from the air given off by a sweeper.
