Unveiling Nature's Warning: Biotic Indicators Of Water Pollution

Bioindicators are living organisms that are used to assess the health of the natural ecosystem in the environment. They are important in indicating water quality and pollution levels. Plankton is a good example of a biotic indicator of polluted water, as it responds rapidly to changes in the surrounding environment and acts as an important biomarker for assessing the quality of water.

Macroinvertebrates are indicator species for freshwater pollution

Macroinvertebrates are insects, crustaceans, and molluscs that play a crucial role in assessing the health of freshwater ecosystems. They serve as biotic indicators of polluted water, providing valuable insights into the overall health and pollution levels of aquatic environments.

These macroinvertebrates are sensitive to changes in water quality, making them ideal indicators of pollution. The Trent Biotic Index, for instance, is a widely used biotic index that assigns tolerance values to different macroinvertebrate species based on their known sensitivity to pollution. By sampling macroinvertebrate communities in rivers, scientists can determine the relative abundance and diversity of pollution-sensitive and pollution-tolerant species. This data is then used to calculate the Trent Biotic Index score, which provides an assessment of water quality and pollution levels.

A high Trent Biotic Index score indicates a healthy and less polluted ecosystem, as it suggests the presence of a diverse community of pollution-sensitive macroinvertebrates. Conversely, a low score indicates poor water quality and higher pollution levels, as pollution-tolerant species dominate the community.

Macroinvertebrates are essential in evaluating the level of water pollution and helping to monitor the impact of pollution on aquatic ecosystems. Their sensitivity to pollution makes them valuable tools for assessing water quality and guiding conservation efforts and water management strategies.

Plankton is an early warning signal for water pollution

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.

Higher biotic index values indicate cleaner or less polluted waters, whilst lower values indicate higher pollution levels. For example, the Trent Biotic Index is a widely used biotic index for assessing freshwater pollution. It focuses on macroinvertebrates (insects, crustaceans, molluscs) as indicator species. The index assigns tolerance values to different species based on their known sensitivity to pollution. By sampling macroinvertebrate communities at various sites in a river, the relative abundance and diversity of pollution-sensitive and pollution-tolerant species are determined. These data are then used to calculate the Trent Biotic Index score, which provides an assessment of water quality and pollution levels in the river. If the Trent Biotic Index score for a particular section of the river is high, it suggests a healthy and less polluted ecosystem, as it indicates the presence of a diverse community of pollution-sensitive macroinvertebrates.

Bioindicators play an important role as Bioindicators and help to evaluate the level of water pollution. In freshwater communities, along with fish, they are the main food supplement to many other marine species (Walsh Citation1978). They are assumed to be a vital part in indicating water quality, eutrophication, and production of a freshwater body. In order to determine the status of a freshwater body, it is necessary to measure seasonal variations and presence of zooplanktons (Zannatul & Muktadir Citation2009). Differing varieties of species, biomass diversity and wealth of zooplankton groups can be utilized to determine the strength of a biological system.

If more detailed information on pollution levels is required, non-living indicators can be used instead. For example, dissolved oxygen meters and chemical tests can be used to very accurately determine the concentration of dissolved oxygen in the water and can be used to show changes in levels of water pollution over time.

There are many different types of biotic indices that can be calculated to study different types of water pollution. For example, the Fine Sediment Sensitivity Index can be calculated to help identify occurrences of sediment pollution in freshwater systems. These biotic indices provide a valuable means to evaluate and monitor the impact of pollution on aquatic ecosystems, aiding in conservation efforts and guiding water management strategies.

Higher biotic index values indicate cleaner or less polluted waters, whilst lower values indicate higher pollution levels.

A biotic index is a tool used to assess the overall health and pollution levels of an ecosystem based on the presence, abundance, and diversity of indicator species within a community. It provides an indirect measure of pollution by evaluating the impact on different species according to their tolerance, diversity, and relative abundance.
