Abstract
Rawapening Lake is located in Semarang Regency, Central Java Province, Indonesia, and is the center of various activities, including agriculture, fisheries, sources of electrical energy, raw water, tourism, and culture. A 100-cm-long sediment sample was extracted from Rawapening Lake to reconstruct the dynamics of environmental change by observing the preserved diatoms. Diatoms are sensitive to changes in water quality, so their pattern of existence can reflect changes in lake conditions. The sampling location is located at the mouth of the Tuntang River, the only outlet of Rawapening Lake, which has 20 inlets as water sources. Sediment cores were sliced at 1-cm intervals for diatom analysis. Diatom slide mounts were prepared from about 5 grams of dry sediment using 10% hydrochloric acid
期刊介绍：
One of the most important challenges facing the contemporary scientific world are problems connected with environmental protection. Intensive development of industry and agriculture has led to a rise in living standards on one hand, but an increase in environmental degradation on the other. This degradation poses a direct threat to human health and life. Solving these ever-increasing problems which seriously endanger our civilization require the united efforts of scientists and field researchers of many branches.
The "Polish Journal of Environmental Studies" publishes original papers and critical reviews on the following subjects:
-Basic and applied environmental pollution research, including environmental engineering
-Pollution control of atmospheric, water (marine and fresh), soil and biological materials
-Determination of harmful substances, including their metabolic breakdown patterns
-Analytical methods for metabolic breakdown patterns or other chemical degradation patterns in the environment and in biological samples
-Development of new analytical methods, instruments and techniques for controlling pollutants
-Circulation of pollutants in the environment and their effect on living organisms
-Environmentally oriented catalysis
-Hazards to human health and safety
-Waste utilization and management
-Land reclamation
-Conference reports, scientific and technical reports and book reviews
