BACKGROUND

Romania became a member of the EU in 2007

Romania transposed the Directive 2008/50/EC of the European

Parliament and of the Council on ambient air quality and

cleaner air for Europe

through a Law (no 104/2011), adopted by the

Romanian Parliament in May 2011

The new law on air quality transposed also the provisions of the

Directive 2004/107/EC

of the European Parliament and of the

Council, relating to arsenic, cadmium, mercury, nickel and

polycyclic aromatic hydrocarbons in ambient air

Through this law were established, at national level, 13

agglomerations, defined as zones that are either

conurbations with a population in excess of 250 000

inhabitants, or, where the population is 250 000 inhabitants

or less, with a density of 3000 inhabitants per km

Also were defined 41 zones for air quality assessment and

The design of the Romanian national air quality

monitoring network

The National Air Quality Monitoring Network (NAQMN) was

established in the period 2005-2007 taking into consideration the

criteria foreseen in the daughters directives and, at the first stage,

included 117 monitoring stations ;

In present, the NAQMN includes:

142 fixed monitoring stations ;

41 laboratories for analysis endowed with necessary

equipment,

42 centers for data processing (1 center at the level of each

zone and 1 national centre for data validation).

(5)

The design of the Romanian national air quality

monitoring network

Monitoring stations are located in accordance with the provisions

of the Directive 2008/50/EC in:

24 traffic locations;

57 industrial locations;

37 urban background locations;

15 suburban background locations;

6 regional background locations;

3 EMEP locations.

(6)

The design of the Romanian national air quality

monitoring network

A traffic station assesses the traffic influence on air quality ;

The measured indicators are: sulfur dioxide (SO2), nitrogen oxides

(NOx), carbon monoxide (CO), ozone (O3), volatile organic

compounds (VOC) and particulate matters .

(7)

The design of the Romanian national air quality

monitoring network

 An industrial station assesses the influence of industrial activities on air quality;

 The measured indicators are: sulfur dioxide (SO2), nitrogen oxides (NOx), carbon

monoxide (CO), ozone (O3), volatile organic compounds (VOC), particulate matters and meteorological parameters (wind speed, wind direction, atmospheric pressure, temperature, solar radiation, relative humidity, precipitations).

(8)

The design of the Romanian national air quality

monitoring network

 An urban background station assesses the influence of integrated contributions from

all sources upwind of the station;

 The measured indicators are: sulfur dioxide (SO2), nitrogen oxides (NOx), carbon

monoxide (CO), ozone (O3), volatile organic compounds (VOC), particulate matters and meteorological parameters (wind speed, wind direction, atmospheric pressure, temperature, solar radiation, relative humidity, precipitations).

Responsibilities of the authorities under NAQMN

LEPAs (local agencies for environmental protection) manage the

local networks for air quality monitoring (at county level) :

measurement, data validation, local air quality assessment, report to

NEPA (National Environment Protection Agency), public information;

NEPA (National Environmental Protection Agency) is in charge with:

data base, data certification, air quality assessment at national level,

report to the MoEF (Ministry of Environment and Forests);

MoEF reports to European and international institutions according to

The design of the Romanian national air quality

monitoring network

The air quality data received from all the 142 fixed monitoring stations as well as meteorological data received from the 119 fixed monitoring stations are sent to the local centers.

The air quality data received from the stations are also sent to panels for public information.

At national level there are 107 panels for public information distributed as follows:

 48 external panels located in highly populated areas from cities or in

pedestrian areas;

 59 internal panels located in the building of public administration office (city

halls, environmental protection agencies, etc).

Also, the air quality data at national level can be accessed on internet webpage :

Overview of data flow system: where and how data are reported

A monitoring station using EDA application: - acquires data;

- executes an automatic preliminary data validation;

- transmits data to local EDAC Center (hourly it establishes an automatic GPRS connection with the local server (EDAC) where it transmits hourly average values and alarms).

EDAC Center stores data from affiliated stations and monitors, manages and integrates all local raw data.

Raw and validated data are transmitted to a central server (from NEPA) using a special software and a high-speed network. Here, the data are viewed by the public or registered web users.

Encountered difficulties :

At national level there is a minimum acceptable number of fixed

sampling points but nevertheless the costs for network’s maintenance

in optimal parameters are very high;

At the network installation were encountered some difficulties in

location of the station mainly due to the owner of the land that

corresponded to the criteria for locating (foreseen in directives)

because private owners or some public institutions could not be

constrained to accept a monitoring station located in their area;

The closing of some industrial facilities implied the relocation of some
