Bioremediation00:46

Bioremediation

20.0K
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.

Comparative Excretory Systems

23.5K
Animals have evolved different strategies for excretion, the removal of waste from the body. Most waste must be dissolved in water to be excreted, so an animal’s excretory strategy directly affects its water balance.

Quality of Water

184
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...

Environmental Applications of Microorganisms

222
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...

Adaptations that Reduce Water Loss01:57

Adaptations that Reduce Water Loss

26.3K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

The Nitrogen Cycle01:49

The Nitrogen Cycle

54.1K
Nitrogen atoms, present in all proteins and DNA, are recycled between abiotic and biotic components of the ecosystem. However, the primary form of nitrogen on Earth is nitrogen gas, which cannot be used by most animals and plants. Thus, nitrogen gas must first be converted into a usable form by nitrogen-fixing bacteria before it can be cycled through other living organisms. The use of nitrogen-containing fertilizers and animal waste products in human agriculture has greatly influenced the...

Área de la Ciencia:

  • Ciencias del medio ambiente
  • Ciencias Agrícolas
  • Ecología

Sus antecedentes:

  • Las pequeñas masas de agua son cruciales para el ciclo de nutrientes en los paisajes agrícolas.
  • Su capacidad de eliminación de nitrógeno (N) a gran escala no se comprende bien.
  • Los campos de arroz son fuentes importantes de emisiones de nitrógeno.

Objetivo del estudio:

  • Evaluar la eficiencia de eliminación de nitrógeno de las tuberías de arroz en las regiones productoras de arroz de China.
  • Evaluar el potencial de las SAE para mitigar la contaminación por nitrógeno procedente de la agricultura.
  • Identificar las estrategias óptimas para mejorar la eliminación de nitrógeno por parte de los SWB.

Principales métodos:

  • Se utilizó un modelo de eliminación de N que incorporaba factores biogeoquímicos.
  • Se han analizado datos de 1,75 millones de SAO (<0,33 ha) en las regiones productoras de arroz de China.
  • Se evaluó el impacto de la distribución de SWB y la cobertura de macrófitos en la eliminación de N.

Principales resultados:

  • Los SWB potencialmente eliminan 169.97 kt N anualmente, el 23.62% de las emisiones nacionales de N de los cultivos, con beneficios económicos de $ 1.68 mil millones de dólares estadounidenses.
  • Existe un desajuste espacial entre la distribución de SWB y los puntos calientes de emisión N.
  • Los aumentos específicos de SWB en áreas críticas y una mayor cobertura de macrófitos (25-50%) pueden mejorar significativamente la eficiencia de la eliminación de N.

Conclusiones:

  • La optimización de la distribución SWB y el aumento de la cobertura de macrófitos son soluciones eficaces basadas en la naturaleza para la contaminación por nitrógeno.
  • La colocación estratégica de los SWB ofrece una mayor eficiencia de eliminación de N que un aumento uniforme.
  • Estas estrategias maximizan los beneficios ecológicos y económicos bajo las limitaciones de los recursos de la tierra.
