DITCHES AND PONDS CAN BE THE SOURCES OR SINKS OF NON-POINT SOURCE POLLUTION: OBSERVATIONS IN AN UPLAND

Frontiers of Agricultural Science and Engineering 2023, Volume 10, Issue 4, Pages 607-626 doi: 10.15302/J-FASE-2023517

Abstract:

As the common features of agroecosystems, ditches and ponds benefit the irrigation and drainage, asFirst, the changes in ponds in the catchment were analyzed using high-resolution remote sensing data.The rate of change in nutrient concentrations in the ditches and ponds were mostly from −20% to20%, indicating ditches and ponds can be both sources and sinks for agricultural pollutants.of ditches and the overflow of ponds in upland areas.

Abundance, spatial distribution, and physical characteristics of microplastics in stormwater detention ponds

Frontiers of Environmental Science & Engineering 2023, Volume 17, Issue 10, doi: 10.1007/s11783-023-1724-y

Abstract: Urban stormwater detention ponds are suitable environments to study the impact of stormwater on the environmentalHerein, we investigate the longitudinal and vertical distribution of MP within two detention ponds withOur findings show that MP are retained more near the inlet of the ponds, and MP of larger sizes were
