Pollution emission monitoring:
I. Port waters pollution monitoring

Port of Gdynia Authority S.A. upon many years has been carrying out port waters quality measurements to control pollution levels in Port of Gdynia. However, due to lack of legal regulations on reference measurements of seawater has always caused problems with classification of port waters quality.
To have more accurate port waters quality results the measurements were carried out in different seasons of the year, on various depth and concentrations of different chemical substances were checked.

	Chart 2. Concentration of chemical substances in port sea water
	Chart 3. pH value in port sea water

In port waters there were following parameters checked:

colour, pH value, odour, suspended solids, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), sulphurs, phosphates, nitrate nitrogen, ammonium nitrogen, total Kjeldahl nitrogen, chlorides, phosphorus, cyanides, fluorides, phenols, aromatic hydrocarbons, oily substances, ether extract, lead, chromium, copper, manganese, iron.

2001-2003 average values are presented below in graphical form.

Above data present concentration levels of particular parameters in port waters. The graph does not include data from water basin no. IV, because during this period there was modernised port sewage system in the area of water basin no. IV and finally connected with municipal sewage system.

Presented data confirms minimal influence of loading and re-loading operations on the water quality.

Since 1st January 2004 there is in force Regulation of Ministry of Infrastructure dated on 23rd January 2003 (Dz.U.2003.35.308) - on the requirements of pollution and energy emission levels measurements that shall be carried by managing authority of the road, rail road, tram road, airport and seaport.

The Regulation determines new reference methods of periodical pollution emission levels measurements in port waters as well as criteria for localisation of measurement points.

The Regulation determines also types of chemical parameters which shall be checked in connection with port operations and they are as follows:

- Biological Oxygen Demand, (BOD)
- Chemical Oxygen Demand, (COD)
- pH value
- dissolved substances
- suspended solids
- Lead
- Zinc
- Cadmium
- oily substances

Port of Gdynia Authority S.A. has already started to carry out port waters quality measurements accordingly with the new regulation.

Pollution emission monitoring:
II. Seabed sediments pollution monitoring

Port of Gdynia Authority S.A. is obliged to check once in every five years the quality of seabed sediments within its water basins. In 2003 the control measurements were carried out according to the procedure given in a Regulation by Ministry of Environment, dated 16th April 2002, on the types and concentration of substances polluting seabed sediments. Before measurements, the Maritime Office in Gdynia had approved the proposal schedule with 116 sample points and there were checked concentrations of below given substances:
metals : - arsine, - chromium, - zinc, - cadmium, - cooper, - nickel, - lead, - mercury; organic compounds: 1) - polycyclic aromatic hydrocarbons (PAHs) benz[a]anthracene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[ghi]perylene, benzo[e]pyrene, dibenz[a,h]anthracene, indeno(1,2,3-c,d)pyrene; - polichlorinated biphenyls (PCBs) 2) Polichlorowanych bifenyli (PCB) sum of following congeners: 28, 52, 101, 118, 138, 153, 180.

Pollution emission monitoring:
III. Air pollution monitoring

Within the area of the Port of Gdynia there is a variety of installations (owed either by Port Authority or private companies) and sources of outdoor air pollution.
The main source of pollution are loading and re-loading operations of bulk cargo within the East Port what results in higher concentration of suspended particulate matter (SPM).
However, in case of the loading and re-loading of bulk cargo Port of Gdynia applied the best available technologies to minimize the emission to the atmosphere.

Port of Gdynia Authority S.A. as well as all remaining port members have got all required by Polish law environmental permissions and documentation concerning air emission, have systematically been monitoring of emitted chemical substances and compounds and regularly pays all environmental fees to Marshal's Office of Pomorskie Voivoship in Gdańsk.

Among the air pollutants there are, owned by Port of Gdynia Authority S.A. and situated all over the port, thermal power plants. In previous five years we closed up all of thermal power plants where heat generations is based on coal burning what resulted in about 40 % reduction of emission to the atmosphere.

Also, Port of Gdynia Authority S.A. is one of the donors of air monitoring equipment for ARMAAG Foundation (Agency of Regional Air Quality Monitoring in Gdańsk) which continuously carries out pollution emission measurements to control the air quality. It provides information of air condition in Gdansk agglomeration and Tczew. Information data are rendered in real time from the automatic measurement network. All measurements results as well as air quality and weather reports are presented on-line (www.armaag.gda.pl). ARMAAG Foundation is a member of European environment monitoring network - EOINET.

In 2002 there were 10 ARMAAG local stations of regional monitoring and one the mobile station for measurements of traffic pollutants DOAS 2000. Station no. AM10 in Gdynia (Wendy Street), where is the highest emission from port and shipyard area following parameters are monitored: nitrogen dioxide (NO2), ammonia (NH3), particulate matter (PM-10) and BTX aromatic hydrocarbons (benzene, toluene, xylene).

Average concentration of nitrogen dioxide (NO2), as given by station no. AM10 (10 [mg/m3]), was just 25% of maximum concentration, thus much lower than maximum concentration (40 [mg/m3]).

Average concentration of particulate matter (PM-10) was about 47,1 [mg/m3] and was exceeded (maximum concentration of particulate matter (PM-10) - 40 [mg/m3]). The analysis of the cause of high particulate matter concentration showed the two main sources of pollution - thermal power plants of Municipal Hospital and NAUTA S.A. Repair Shipyard, where heat generation is based on coal burning.

Maximum concentration of toluene and xylene occurred while north-east and north-west winds. NE and NW directions indicates as sources of pollution Gdynia S.A. Shipyard, Naval Shipyard and NAUTA S.A. Repair Shipyard. Average concentration of benzene was 2 [mm/m3], when maximum concentration of benzene in air is 5 [mg/m3].
