Abstract
Abstract: Typha latifolia leaves act as sensitive barometers for trace heavy metal pollution, as revealed
by their pronounced anatomical responses in a constructed wetland. Monthly water samples and
Typha latifolia leaf tissue were collected over three consecutive months in 2018 from the Burgas
Lake wetlands (Taoura), northeast Algeria. While physical and chemical parameters improved after
treatment, atomic absorption spectrometry (Perkin Elmer A Analyst 800 AAS) detected persistent
trace levels of cadmium, chromium, and lead in both the treated water and leaf tissue, highlighting
the need for continued phytoremediation efforts. Microscopic examination of leaf tissue exposed
to these metals revealed distinct anatomical adaptations, including shrunken vascular bundles,
altered cell shapes, and stomatal closure. These findings underscore Typha latifolia’s effectiveness in
accumulating heavy metals and its potential as a highly sensitive biomonitor for persistent pollution
in lake ecosystems.
