Abstract—When the ecological river restoration projects
using the concrete material are performed, various biological
problems can occur as a result of that water quality degradation
due to strong alkali and heavy metal such as lead and chromium
and exposure of aquatic organisms to toxic environments
during long term. Thus, in this study, biological monitoring
(biomass and community characteristics, etc.) and health
evaluation were carried out by attached algae using application
of vegetation-based polyurethane as non-toxic material for the
ecological restoration of rivers. Experiments are evaluated
ecological property for non-toxic materials using concrete
bricks, coated plant-based polyurethane concrete bricks and
natural stone. In addition, the target river was investigated by
basic biological research.
Index Terms—Non-toxic material, plant-based polyurethane,
ecological health, periphyton, monitoring.
