Environmental Monitoring and Assessment
|November 25, 2025
Summary
Shrimp effectively indicate water pollution levels by accumulating contaminants. Examining these benthic organisms provides a more reliable assessment than water sampling alone, especially considering environmental variability.
Area of Science:
- Environmental Science
- Marine Biology
- Biomarker Research
Background:
- Increasing water and marine pollution necessitates reliable assessment methods.
- Traditional water sampling can be unreliable due to atmospheric influences.
- Benthic organisms like shrimp can accumulate pollutants, offering an alternative assessment approach.
Purpose of the Study:
- To systematically investigate the utility of shrimp as bioindicators for assessing water pollution.
- To evaluate the effectiveness of shrimp in reflecting the true extent of aquatic contamination.
Main Methods:
- Conducted a systematic literature review by searching scientific databases.
- Screened and selected 17 relevant manuscripts for full data extraction.
- Analyzed studies focusing on protein biomarkers and enzyme activities in shrimp.
Main Results:
- Protein biomarkers (e.g., metallothionein) and enzymes (e.g., cholinesterases) were key indicators in shrimp.
- Trace metals and Polycyclic Aromatic Hydrocarbons (PAHs) were the most commonly studied pollutants.
- Shrimp bioaccumulation provides a valuable measure of pollutant levels.
Conclusions:
- Shrimp serve as effective bioindicators for monitoring water and sea pollution.
- Biomarker analysis in shrimp offers a robust method for environmental pollution assessment.
- This approach overcomes limitations associated with direct water sampling.

01:19Quality of Water
In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...
01:14Testing Water Quality
When the quality of water for concrete preparation is uncertain, its impact on the setting time of cement and compressive strength of mortar is assessed by comparison with de-ionized or distilled water benchmarks. American Society for Testing and Materials (ASTM) C1602 requires the setting times to be within 90 minutes of the control, British Standard (BS) 3146:1980 allows a 30-minute variance in the initial setting, while British Standards European Norm (BS EN) 1008 specifies initial setting...
01:30Environmental Applications of Microorganisms
Microorganisms play a pivotal role in maintaining ecosystem balance by recycling essential elements such as carbon, nitrogen, and phosphorus, as well as supporting processes like bioremediation, wastewater treatment, and biofuel production.Microbes in Elemental CyclesIn the carbon cycle, microorganisms decompose organic matter, releasing carbon dioxide via aerobic respiration. This carbon dioxide is subsequently used by photosynthetic organisms to synthesize organic compounds, closing the...
01:30Biological Treatment of Effluent and Waste Water
Biological wastewater treatment relies on the metabolic activity of microorganisms to remove pollutants from sewage. In modern treatment systems, this process is organized into sequential stages that progressively reduce solid material, dissolved organic matter, and microbial contamination. Each stage plays a distinct role in improving water quality and preparing the effluent for safe discharge or reuse.Primary and Secondary TreatmentPrimary treatment is a physical process that removes large...
