The Research Progress of the Influence of Agricultural Activities on Atmospheric Environment in Recent Ten Years: A Review

Abstract

In recent years, the industrial emission of air pollution has been reduced via a series of measures. However, with the rapid development of modern agriculture, air pollution caused by agricultural activities is becoming more and more serious. Agricultural activities can generate a large amount of air pollutants, such as ammonia, methane, nitrogen oxides, volatile organic compounds, and persistent organic pollutants, the sources of which mainly include farmland fertilization, livestock breeding, pesticide use, agricultural residue burning, agricultural machinery, and agricultural irrigation. Greenhouse gases emitted by agricultural activities can affect regional climate change, while atmospheric particulates and persistent organic pollutants can even seriously harm the health of surrounding residents. With the increasing threat of agricultural air pollution, more and more relevant studies have been carried out, as well as some recommendations for reducing emissions. The emissions of ammonia and greenhouse gases can be significantly reduced by adopting reasonable fertilization methods, scientific soil management, and advanced manure treatment systems. Regarding pesticide use and agricultural residues burning, emission reduction are more dependent on the restriction and support of government regulations, such as banning certain pesticides, prohibiting open burning of straw, and supporting the recycling and reuse of residues. This review, summarizing the relevant research in the past decade, discusses the current situation, health effects, and emission reduction measures of agricultural air pollutants from different sources, in order to provide some help for follow-up research.

Chemical Characteristics and Cytotoxicity to GC-2spd(ts) Cells of PM2.5 in Nanjing Jiangbei New Area from 2015 to 2019

“…Straw burning had long been banned, but this phenomenon persisted in the suburbs. In addition, crop residues were often used as kitchen firewood in rural areas, which contributed to the emissions from biomass burning source [ 82 ].…”

A synergistic combination of 2D MXene and MoO3 nanoparticles for improved gas sensing at room temperature

“…Based on this literature survey, in this work, we have developed a Ti 3 C 2 T x -MoO 3 system for ammonia gas sensing. Ammonia is one of the primary gases which is released by industries and agricultural functions as an air pollutant [33,34]. Inhalation of this gas has many consequences, from minor to severe [35].…”

Assessing the Influence Factors of Agricultural Soils’ CH4/N2O Emissions Based on the Revised EDGAR Datasets over Hainan Island in China

“…CH 4 and N 2 O, also known as noncarbon-dioxide greenhouse gases (GHG-NCO 2 ), have warming potentials 25 and 298 times greater than CO 2 over a 100-year period, respectively [8]. In recent years, GHG-NCO 2 have received significant attention in the fields of atmospheric science and ecology due to the challenges associated with accurately calculating emissions and the wide range of sources of these gases [9,10].…”

“…Agriculture is a significant contributor to greenhouse gas (GHG) emissions in the atmosphere [10]. Globally, agricultural activities account for 24% of total GHGe [11].…”
