The
present information is about a description of the equipment and
procedures used in the permanent monitoring of dioxide of sulfur
and meteorological information, developed in the city of Ilo being
focused to evaluate the contamination of the air for the presence
of SO2, due to its impact in the public health. |

The
city of Ilo is located in the south coast from Peru to 1250 Km of
Lima and 200 Km. to the north of the frontier with Chile.
One of the main environmental problems in the city is the atmospheric
contamination.
The continuous monitoring has as purpose to measure the pollutants
coming from the industry miner just as the SO2, these obtained data
are part of the database of quality of air, the same ones that are
using in the elaboration of the study of monitoring of quality of
the air in the Zonal Gesta of Air in order to improve the quality
of air in Ilo. |

To reach the data to the government and such involved institutions
as: Ministry of Health, General Address of Environmental
Health, Ministry of Energy and Mines among other
that which has been good to regulate the standards
of quality of air in our country, such it is so starting from June
of the 2001 they exist Standard of Quality of Air for the Peru,
approved with D.S. 074 –2001 –PCM. |

| The
Permanent Monitoring of Quality of Air has five automatic analyzers
of SO2, that carry out a continuous monitoring and they are distributed
strategically in the whole city of Ilo, it covers the rural and urban
area. |
|
|
|
In
this study we use 5 automatic analyzers of SO2 Thermo Environmental
Instruments Model 43W of ultraviolet absorption that measure
the concentration of SO2 continually in the atmosphere. The analyzing
suck the air of the atmosphere through a funnel and a teflón
hose, which are located to the atmosphere, to not less than 3 meters
on the level of the floor. The air enters to the camera of mensuration
of the automatic monitor of SO2 and it emits a sign in Volts, to
a system of acquisition of data. The system of acquisition of data
is installed in a computer. The card of data, transforms the voltage
into real values of concentration of SO2 in microgrames for cubic
meter (µg/m3) and then the computer records the data in the
hard disk. |

Simultaneously
the data are recorded in the DATALOGGER and correspondents to the
central office through the modem. This way of transmission of the
information, allows us a control easy of the operation of the equip,equipments,
and it also allows us to implement a system of protection environmental
denominated Plan of Contingency. These monitors receive maintenance
and calibration every 15 days, for those that are used standard
of calibration to two concentrations: 0 and 5 PPM SO2. Also it is
carried out a calibration multipoint monthly what will give the
dependability of the linely of the equipments, according to protocols
of the EPA (EPA, 1994), what will allow us a calibration of more
precision. |
