Moss Biomonitoring of air pollution with chromium in Croatia

Biomonitoring of air pollution by using moss samples is widespread in Europe. More investigations and surveys were carried out in order to examine air quality. Croatia participated twice in a moss survey in the framework of the International Cooperative Programme on Effects of Air Pollution on Natural Vegetation and Crops with Heavy Metals in Europe (UNECE ICP Vegetation). For the first time Croatia participated in 2006 and the second time in 2010. During the summer and autumn of 2010, moss samples were collected from 96 sites evenly distributed over the country. Chromium was determined by using atomic emission spectrometry with inductively coupled plasma (lCPAES) after previous microwave digestion of moss samples. The median value of chromium content (1.83 mg kg, l) was found to be lower than the same value in 2006 (2.8 mg kg· I). Chromium content ranges from 0.41 mg kg· 1 to 7.78 mg kg· l. Maps of distribution of chromium from the surveys in 2006 and 2010 will be compared. Some anthropogenic sources in/around Zagreb, Sisak and Kutina were found.
