Single pollution index ( Yang et al., 2014 ) was used to find the heavy metal pollution level in all the three experimental sets at 60 days as per the following equation-. Yang et al., 2011. Individual variable assessment is performed regarding TPH ( Pinedo et al., 2013 ) to find out the number of locations classified as seriously contaminated which is as follows:. C i f is the single pollution index ( Guo et al., 2010.

Heavy metal accumulation as a threat to the endangered Egyptian vulture (Neophron percnopterus L.) in Turkey

tailieu.vn

Heavy metal pollution is one of the most important threats to marine (Ling et al., 2018), freshwater (Abdelhady et al., 2019), and terrestrial (Belskii and Mikryukov, 2018) biodiversity. Exposure to heavy metals has resulted in growth and developmental abnormalities, detrimental effects on productivity, and death in animals (Migliarini et al., 2005. Hargitai et al., 2016. Pavlaki et al., 2016. Zeng et al., 2019)..

Study on the potential to absorb heavy metal (FE, CU, MN) in contaminated water by Centella asiatica

tailieu.vn

In this study shows that after 10 days, Centella asiatica’s metal processing started to stabilize.. The ability accumulation of Centella asiatica with Cu is biggest (equal 62.5%) compared to Mn (equal 30%) and Fe (equal 22.5. In addition, Centella asiatica also helps to create conditions to increase the pH of the water, which is an important condition for metal treatment processing in the limited financial investment and also reducing secondary pollution.
