After sugarcane bagasse and maize straw, rice straw (RS) is globally the third largest form of agricultural residue while, in India, it residue. In north-western states India wheat taken as a rabi crop surplus focal issue associated with storage removal entire from field, very little time between cultivation hence burning becomes cheap, quick efficient way for preparing bed sowing wheat. Open k...
To better understand the characteristics of biomass burning in the northern Indo-Gangetic Plain (IGP), total suspended particles were collected in a rural site, Lumbini, Nepal, during April 2013 to March 2014 and analyzed for the biomass burning tracers (i.e., levoglucosan, mannosan, vanillic acid). The annual average concentration of levoglucosan was 734± 1043 ng m−3 with the maximum seasonal ...
The impact of crop residue burning in northeastern China on South Korean PM2.5 concentrations was assessed via weather conditions, air quality modeling (AQM), and composition data during two cases exceeding 35 µg·m−3 November 2015. concentration simulations Case 1 differed from observations by 3.7–17.6 µg·m−3, overestimating the levels 6–36%; however, 2 varied 20.0–59.8 observations, with a 53–...
In this study, we integrated a remote-sensing fire product (MOD14A1) and land-use (MCD12Q1) to extract the number of crop-residue burning (CRB) spots radiative power (FRP) in China from 2001 2018. Moreover, conducted three trend analyses two geographic distribution quantify interannual variations summarize spatial characteristics CRB on grid (0.25° × 0.25°) regional scales. The results indicate...
in this study, the effect of nanoclay particles content on the physical properties and flammability of composite made of high density polyethylene and wood flour was investigated. for this aim, wood flour was combined with hdpe at 50% by weight, and nanoclay was used in 0, 2, 4 and 6%, also 2% of mape as the coupling agent was used in all formulations. the samples were made in injection molding...
Returning residue to soils is not only an effective nutrient management method, but also can reduce the air pollution caused by burning, which has become important factor in global warming. However, it clear whether returning soil affect nitrogen mineralization and cycle process, environmental impact loss gaseous forms. Therefore, a pot experiment was conducted study effects of placement on tur...
