Biomonitoring of metal(oid)s in mining-affected Borcka Dam Lake coupled with public health outcomes
(Taylor & Francis Inc, 2018)
Due to increased anthropogenic activities, the aquatic environment is exposed to pollutants much more than ever. These pollutants go into the food chain and can pose a health risk to human. Correlatively, Borcka Dam Lake, ...
Contribution to the pollen morphology of Tragopogon (Asteraceae) in Turkey
(Magnolia Press, 2018)
The pollen morphology of 25 Tragopogon L. taxa (including four subspecies and four varieties) distributed in Turkey was studied under light and scanning electron microscopy. It was observed that pollen grains of the examined ...
