Bioindicators: the natural indicator of environmental pollution

Abstract

Bioindicators are living organisms such as plants, planktons, animals, and microbes, which are utilized to screen the health of the natural ecosystem in the environment. They are used for assessing environmental health and biogeographic changes taking place in the environment. Each organic entity inside a biological system provides an indication regarding the health of its surroundings such as plankton responding rapidly to changes taking place in the surrounding environment and serving as an important biomarker for assessing the quality of water as well as an indicator of water pollution. Even the health of aquatic flora is best reflected by plankton, which acts as an early warning signal. In this review we have tried to explain the concept behind Bioindicators and plankton, with particular emphasis on their potential to be used as Bioindicators for water quality assessment and outcomes relating to this.

Frog as Sentinel of Human Cancer Incidence in Southern Italy’s So-Called ‘Terra dei Fuochi’

“…Other studies were conducted on hair and blood from healthy pet dogs, assaying the concentration of heavy metals [55]. Likewise, we suggest concentrating investigations on DNA damage in wild animals closer to legal and illegal waste dumping, and they represent a previous step to the disease on human populations [56]. This result is a further confirmation of how our animal (Pelophylax kl.…”

Comparing the functional recognition of aesthetics, hydrology, and quality in urban stream restoration through the framework of environmental perception

“…The growth in environmental indicators often reflects variations in the objective values of stream restoration (Machado, ). Thus, water quality and water temperature are often used to evaluate river restoration projects in the short term (Parmar, Rawtani, & Agrawal, ). Residents consider that stream restoration is necessary because most of the streams that are scheduled to be restored are suffering from pollution in the river ecosystem.…”

Duality of Seasonal Effect and River Bend in Relation to Water Quality in the Chao Phraya River

“…In comparison, the microbial communities of rivers and streams have been studied relatively rarely [11]. Moreover, phytoplankton plays a central role in the functioning of freshwater ecosystems, such as nutrient cycling, and thereby can serve as bio-indicator of environmental changes, since its assemblage is always influenced by environmental factors [12,13]. Thus, efforts to combine chemical, bacterial, and phytoplankton information will certainly deepen our understanding of water quality variation and lead to better river management.…”
