Multivariate analysis used for evaluation of the bioavailability of heavy metals in various composts
Summary.

Background. Sewage sludge is an urgent environmental problem, which can easily cause secondary pollution. Therefore, it is very important to handle it properly. Composting is a rational method of sewage sludge handling. Composts are valuable sources of nutrients, but at the same time they may pollute the environment with heavy metals. There are various methods of analysis of heavy metals, but there is no method which would provide reliable information about the bio­availabity of heavy metals in various composts.

Materials and methods. The experiment was conducted on 4 different composts made from sewage sludge and bulking agents. The data were analysed by means of multivariate statistical techniques such as MANOVA, Tukey’s test for multiple comparisons, principal component analysis and cluster analysis.

Results. The aim of the study was to verify whether multivariate techniques could evaluate the usability of different extractants for assessment of the bioavailability of heavy metals in various composts.

Conclusions. Multivariate statistical techniques help to interpret complex data, where compost, metals and extractants can be analysed in combination. It helps to understand the influence
of extractants and metals in the study of sewage sludge.

Key words: bioavailability, composts, heavy metals, extractants, multivariate statistical analysis
