Filtration and Urine Formation01:32

Filtration and Urine Formation

53.2K
The function of the kidneys is to filter, reabsorb, secrete, and excrete. Every day the kidneys filter nearly 180 liters of blood, initially removing water and solutes but ultimately returning nearly all filtrates into circulation with the help of osmoregulatory hormones. This process removes wastes and toxins but is also crucial to maintain water and electrolyte levels. Most of these functions are performed by the tiny but numerous nephrons contained within the kidneys.

Bioremediation00:46

Bioremediation

22.0K
Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Environmental 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...

Filtration00:53

Filtration

4.8K
Filtration is a physical separation process that involves passing a suspension through a porous medium to separate solids from fluids. During filtration, solids collect on the porous medium while liquids, also collectively known as the filtrate, pass through. The filtration medium is selected based on the filtration purpose, quantity, and nature of the precipitate. The general criteria for a suitable filtering medium are that it is inert, mechanically strong, nonabsorbent toward dissolved...

Biofilms01:29

Biofilms

1.1K
Biofilms are complex communities of microorganisms encased in a self-produced extracellular polysaccharide matrix attached to surfaces. These microbial consortia can include single or multiple species, providing enhanced survival benefits by forming organized, multilayered structures.The formation of biofilms occurs through four key stages: attachment, colonization, development, and dispersal.During attachment, free-swimming planktonic cells adhere to a surface, often facilitated by...

Area of Science:

  • Environmental Science
  • Environmental Chemistry
  • Urban Hydrology

Background:

  • Microplastic pollution is a growing concern in urban environments.
  • Bioretention filters are potential solutions for treating contaminated urban stormwater.
  • Understanding microplastic pathways in these filters is crucial for effective management.

Purpose of the Study:

  • To identify the occurrence and pathways of microplastics in bioretention filters.
  • To analyze microplastic types and concentrations in soil and stormwater.
  • To evaluate the efficiency of bioretention filters in microplastic removal.

Main Methods:

  • Collected soil and stormwater samples from urban bioretention filters.
  • Analyzed microplastics (>10 µm) using Thermal Extraction and Desorption Gas Chromatography-Mass Spectrometry (TED-GC/MS).
  • Analyzed larger microplastics (>27 µm) in stormwater using pyrolysis PYR-GC/MS.

Main Results:

  • Polyvinyl chloride (PVC), polyethylene terephthalate (PET), and polystyrene (PS) were the most common polymers.
  • Higher concentrations of polar polymers like PET were found in water samples, indicating differential retention.
  • Microplastic concentrations were highest in the upper soil layers, showing effective capture.

Conclusions:

  • Bioretention filters are efficient in reducing microplastic spread from impervious surfaces.
  • The filters effectively accumulate microplastics in the soil, preventing release into surface waters.
  • Further research is needed to optimize bioretention systems and address analytical uncertainties.
