Ecological monitoring in gas field Molve

Technological process of exploration, production, transport, processing and refining of the natural gas in the gas-condensate fields of Podravina, northwestern Croatia, has been conceived with the tendency to hinder in full environment pollution. In addition to this, by ecological monitoring the possible impact of the oil mining on the environment is being controlled. During the last twenty years, according to the Program on determination of the environment condition that has been implemented in cooperation with great number of researchers of different skills, the risks of the oil industry on human health and environment have been determined and by improvement of technological processes decreased. A great number of the scientific institutions and individuals take part in the preparation and implementation of ecological researches and analyses, processing and interpretation of results. This paper comprises the part of these activities and ecological researches with a special emphasis on the air quality control. The results of the mean annual concentrations of the hydrogen sulphide and mercaptan in 1991, 1996 and 2002 were shown with the commentary about the decrease of the concentrations during 1996 and 2002 as compared to 1991 ; a part of results of research of mercury in the air from 1995 to 1997 and from 1999 to 2000 has also been shown.
