Special Issue Information

Dear Colleagues,

This Special Issue will be devoted to healthy farming and environmental pollution. We call for papers focused on the state of the science in the prediction of health farming, livestock waste treatment, health impacts, risk assessment and pollution control and management strategies.

The livestock and poultry breeding industry is an important part of agriculture, which not only guarantees the demand of people all over the world for livestock and poultry products but is also the pillar industry of the agricultural economy in many countries. As a contradiction between the production and consumption demand of livestock and poultry products, the protection of breeding land and cultivated land, livestock waste pollution and ecological environment maintenance have become increasingly serious, and healthy farming has become an urgent matter in the development of animal husbandry globally. In recent years, many insiders have mentioned and promoted "healthy farming". Overall, healthy farming requires the unified and coordinated development of animal health, product safety and environmental protection to form sustainable ecological agriculture. A good environment is also a prerequisite for the healthy and sustainable development of livestock farming. The production of livestock waste (livestock feces, wastewater, biogas residue, etc.) is huge, which poses a great threat to the environment (water quality, soil, air, etc.), and can cause atmospheric odor pollution, water pollution, soil pollution and biological pollution. Livestock waste contains a large amount of nutrients (N, P, etc.), thus having enormous potential in resource utilization. The United States has adopted the combination of agriculture and animal husbandry to prevent and control breeding pollution by forming a "forage, feed and fertilizer cycle" system inside farms. 

This Special Issue of the International Journal of Environmental Research and Public Health (IJERPH) focuses on the current state of knowledge on the links between healthy farming and environmental health. Short communications, original papers and review articles are welcome to this issue.

The topics of interest include, but are not limited to, the following:

  1. Impact of livestock waste on health and the environment;
  2. Livestock waste management processing technology;
  3. The fate and health risk of emerging pollutants (antibiotics, ARGs, etc.) in livestock farming environments;
  4. Environmental impact and control of malodorous gases from livestock and poultry farms;
  5. Influence and risk assessment of livestock manure on farmland ecological environments;
  6. Management strategies and technical means for safe utilization of livestock manure and fertilizer.

Little is known about the fate of heavy metals in the recycling system of animal manure–black soldier fly larvae (BSFL) transformation-larval frass application. In this work, BSFL-transformed pig manure with different concentrations of exogenous cadmium (Cd) (0, 3, 15, 30 mg kg−1), and the obtained BSFL frass fertilizer were further used in pot experiments of maize planting to explore Cd migration during the whole recycling system. Results showed that Cd addition to pig manure had no significant effects on BSFL growth or BSFL transformation performance. The Cd concentrations in BSFL frass were 10.9–19.8% lower than those in pig manure, while those in BSFL bodies were 2.3–4.0-times those of pig manure. For maize planting, only 30 mg kg−1 of Cd treatment significantly inhibited maize growth. The BSFL frass application (under exogenous Cd treatment) enhanced Cd contents in the aboveground and underground parts of maize (3.3–57.6-times) and those in soil (0.5–1.7-times) compared with CK (no Cd addition). Additionally, 61.2–73.5% of pig manure-sourced Cd was transformed into BSFL frass and the rest entered BSFL bodies. Only a small part (0.31–1.34%) of manure-sourced Cd entered maize plants. BSFL transformation decreased the proportions of weak acid-dissolved Cd from 44.2–53.0% (manure) to 37.3–46.0% (frass). After frass application, the proportions of weak acid-dissolved Cd in soil were further decreased to 17.8–42.5%, while the residual fractions of Cd increased to 27.2–67.7%. The findings provided a theoretical basis for the rational application of BSFL frass fertilizers sourced from heavy-metal-contaminated manure. Full article

Dairy manure is a nutrition source for cropland soils and also simultaneously serves as a contamination source of antibiotic resistance genes (ARGs). In this study, five classes of antibiotics including aminoglycosides, beta-lactams, macrolides, sulfonamides, and tetracyclines, were spiked in dairy manure and incubated with soil for 60 days. The high throughput qPCR and 16S rRNA amplicon sequencing were used to detect temporal shifts of the soil antibiotic resistomes and bacterial community. Results indicated dairy manure application increased the ARG abundance by 0.5–3.7 times and subtype numbers by 2.7–3.7 times and changed the microbial community structure in soils. These effects were limited to the early incubation stage. Selection pressure was observed after the addition of sulfonamides. Bacterial communities played an important role in the shifts of ARG profiles and accounted for 44.9% of the resistome variation. The incubation period, but not the different antibiotic treatments, has a strong impact on the bacteria community. Firmicutes and Bacteroidetes were the dominant bacterial hosts for individual ARGs. This study advanced our understanding of the effect of dairy manure and antibiotics on the antibiotic resistome in soils and provided a reference for controlling ARG dissemination from dairy farms to the environment.

In order to improve the phosphate adsorption capacity of Ca-loaded biochar at a wide range of pH values, Ca (oyster shell) was loaded as Ca(OH)2 on the tobacco stalk biochar (Ca-BC), which was prepared by high-temperature calcination, ultrasonic treatment, and stirring impregnation method. The phosphorus removal performance of Ca-BC adsorption was studied by batch adsorption experiments, and the mechanism of Ca-BC adsorption and phosphorus removal was investigated by SEM-EDS, FTIR, and XRD. The results showed that after high-temperature calcination, oyster shells became CaO, then converted into Ca(OH)2 in the process of stirring impregnation and had activated the pore expansion effect of biochar. According to the Langmuir model, the adsorption capacity of Ca-BC for phosphate was 88.64 mg P/g, and the adsorption process followed pseudo-second-order kinetics. The Ca(OH)2 on the surface of biochar under the initial pH acidic condition preferentially neutralizes with H+ acid-base in solution, so that Ca-BC chemically precipitates with phosphate under alkaline conditions, which increases the adsorption capacity by 3–15 times compared with other Ca-loaded biochar. Ca-BC phosphate removal rate of livestock wastewater (pig and cattle farms) is 91~95%, whereas pond and domestic wastewater can be quantitatively removed. This study provides an experimental basis for efficient phosphorus removal by Ca-modified biochar and suggesting possible applications in real wastewater. Full article

Antibiotics are used extensively throughout the world and their presence in the environment has caused serious pollution. This review summarizes natural methods and enhanced technologies that have been developed for antibiotic degradation. In the natural environment, antibiotics can be degraded by photolysis, hydrolysis, and biodegradation, but the rate and extent of degradation are limited. Recently, developed enhanced techniques utilize biological, chemical, or physicochemical principles for antibiotic removal. These techniques include traditional biological methods, adsorption methods, membrane treatment, advanced oxidation processes (AOPs), constructed wetlands (CWs), microalgae treatment, and microbial electrochemical systems (such as microbial fuel cells, MFCs). These techniques have both advantages and disadvantages and, to overcome disadvantages associated with individual techniques, hybrid techniques have been developed and have shown significant potential for antibiotic removal. Hybrids include combinations of the electrochemical method with AOPs, CWs with MFCs, microalgal treatment with activated sludge, and AOPs with MFCs. Considering the complexity of antibiotic pollution and the characteristics of currently used removal technologies, it is apparent that hybrid methods are better choices for dealing with antibiotic contaminants.
