Threshold Reaction of Soil Arthropods to Simulative Nitrogen Deposition in Urban Green Spaces

Frontiers in Ecology and Evolution, 2021
Sustained nitrogen (N) deposition has a wide-ranging impact on terrestrial ecosystems. However, still little attention has been paid to responses of urban soil fauna to the increasing N deposition.

Effects of wastewater treatment plant pollution on in-stream ecosystems functions in an agricultural watershed [PDF]

, 2009
We studied the effect of point-source and non-point-source pollution on the retention capacity of the stream and its link with the metabolic state (primary production and respiration) and invertebrates assemblages in a third order Mediterranean stream ...

Phase Field Modeling of Anisotropic Tension Failure of Rock-Like Materials

Frontiers in Physics, 2021
The tensile fracture is a widespread feature in rock excavation engineering, such as spalling around an opened tunnel. The phase field method (PFD) is a non-local theory to effectively simulate the quasi-brittle fracture of materials, especially for the ...

Nitrogen Dynamics and Environmental Sustainability in Rice–Crab Co-Culture System: Optimal Fertilization for Sustainable Productivity

AgriEngineering
Rice–crab co-culture systems (RC) represent promising sustainable intensification approaches, yet their nitrogen (N) cycling and optimal fertilization strategies remain poorly characterized. In this study, we compared RC with rice monoculture system (RM)

Improvement on Management of Non-point Source Pollution for Reasonable Implementation of TMDL - Focusing on Selection of Non-point Source Pollution Management Region and Management of Non-point Source Pollutant -

Journal of Korean Society of Environmental Engineers, 2014
For effective implementation of total maximum daily load (TMDL), this study presented the improving plans of nonpoint source pollution management including the classification of non-point source pollution, calculation of non-point source pollution load (generated, discharged), selection of non-point source pollution management regions and management of

Impacts of Non-Point Source Pollution Regulations on Mississippi Agriculture [PDF]

Journal of Agricultural and Applied Economics, 1979
The Federal Water Pollution Control Act of 1972, PL92-500, established the goals of making the nation's streams and lakes swimmable and fishable by 1983 and eliminating both point and non-point pollution discharge by 1985. Implementation of this act, even if carried out uniformly and on the basis of scientifically determined information, could have far-
