Distribution of lead in the waters, sediment, rice and vegetable crops in the basin of the river Bregalnica

摘要

During the period from January to December 1999 year and 2000, 2007 and 2008 field research has been made at 20 measuring points on the river Bregalnica together with its tributaries. The research made during these year on the territory of East Macedonia had an aim to establish the degree of water pollution in the river Bregalnica with its tributaries, and distribution of lead in the sediment, rice and vegetable crops in the basin of the river Bregalnica pollution with heavy metals as a result of direct release of waste water from lead-zinc mines “Zletovo” and “Sasa” as well as from copper mine “Bucim”. From the results acquired research while the annual an seasonal dynamics of the lead content in the river Bregalnica with its tributaries was monitored, it can be seen that there is a variation in the values of a relatively wide range between respective measuring sites, monthly variations, which id the consequence of anthropogenic influence upon the living environment.
