AbstractTraditional breeding techniques, applied incrementally over thousands of years, have yielded huge benefits in the characteristics of agricultural animals. This is a result of significant, measurable changes to the genomes of those animal species and breeds. Genome editing techniques may now be applied to achieve targeted DNA sequence alterations, with the potential to affect traits of interest to production of agricultural animals in just one generation. New opportunities arise to improve characteristics difficult to achieve or not amenable to traditional breeding, including disease resistance, and traits that can improve animal welfare, reduce environmental impact, or mitigate impacts of climate change. Countries and supranational institutions are in the process of defining regulatory approaches for genome edited animals and can benefit from sharing approaches and experiences to institute progressive policies in which regulatory oversight is scaled to the particular level of risk involved. To facilitate information sharing and discussion on animal biotechnology, an international community of researchers, developers, breeders, regulators, and communicators recently held a series of seven virtual workshop sessions on applications of biotechnology for animal agriculture, food and environmental safety assessment, regulatory approaches, and market and consumer acceptance. In this report, we summarize the topics presented in the workshop sessions, as well as discussions coming out of the breakout sessions. This is framed within the context of past and recent scientific and regulatory developments. This is a pivotal moment for determination of regulatory approaches and establishment of trust across the innovation through-chain, from researchers, developers, regulators, breeders, farmers through to consumers.

Glyphosate [N-(phosphonomethyl) glycine] (GPS) is currently the most commonly applied herbicide worldwide. Given the widespread use of glyphosate, the investigation of the relationship between glyphosate and soil ecosystem is critical and has great significance for its valid application and environmental safety evaluation. However, although the occurrence of glyphosate residues in surface and groundwater is rather well documented, only few information are available for soils and even fewer for air. Due to this, the importance of developing methods that are effective and fast to determine and quantify glyphosate and its major degradation product, aminomethylphosphonic acid (AMPA), is emphasized. Based on its structure, the determination of this pesticide using a simple analytical method remains a challenge, a fact known as the “glyphosate paradox.” In this chapter a critical review of the existing literature and data comparison studies regarding the occurrence and the development of analytical methods for the determination of pesticide glyphosate in soil and air is performed.

The purpose of this article is to present a new calibration procedure for spectroscopic measurements using an infrared focal plane array (IRFPA) spectrometer on highly opaque middle-wave infrared (MWIR) media. The procedure is based on the properties of the IRFPA camera and especially the integration time (IT), which is the main parameter that can be adjusted to control the sensitivity of the measurements. The goal of the paper is to experimentally validate this dependence with the direct reference intensity light coming out of the IR monochromator in order to predict the spectrum shape and intensity level in a range out of the camera saturation. This method allows determining spectrum used as background for transmittance calculation. It has been applied in the case of measurement of water transmittance, which is a highly opaque medium and whose measurement requires high ITs. The main result is the ability to take an IR spectroscopic imaging measurement through 300 µm of water and the determination of its transmittance with sufficient sensitivity due to the proposed calibration procedure. This procedure allows the possibility of transitory studies in heterogeneous aqueous media.

Objective: In this paper, we evaluate the effectiveness of agricultural approaches and manufacturing techniques that can be applied to reduce nicotine content of tobacco to minimally addictive levels (< 0.4 mg/g). Methods: Using a semi-structured approach, we searched scientific and grey literature including patents and internal industry documents, using keywords like tobacco, nicotine, alkaloids, denic(otinized) tobacco, reduced nicotine content, very low nicotine tobacco. Results: Nicotine can be reduced via genetic modification or traditional breeding techniques. Contents and emissions are similar to regular cigarettes, but consumers rated them as less satisfactory. Extraction techniques yield less palatable tobacco too, due to co-extraction of favor components in tobacco. Microbial and enzymatic degradation lead to other, mostly undesirable, changes to tobacco. Supercritical extraction resulted in a taste most similar to regular cigarettes, but still failed in the marketplace. Conclusions: Most of the available techniques are successful in reducing nicotine levels, sometimes to levels lower than 0.4 mg/g. However, in almost all cases, the resulting tobacco leads to a less satisfactory smoking experience. Although reduction of nicotine to a non-addictive level is feasible from a technical perspective, it is not clear whether such measures could be successfully implemented.

The percentage of solid waste services Denpasar City in 2013 reached 51,8 percent, the limited number and capacity TPS in Denpasar not meet the needs of waste management services in denpasar. The study was to examine the relevant strategies appropriate to the criteria and requirements related to the determination of the location of TPS and the land need. The position of the study is Part Of The City (BWK) Central in Denpasar. Analysis of technical aspects will evaluation garbage production in order to know the ideal needs of TPS, the evaluation of TPS placement based on the function of the area and the land needed. Environmental aspect will analyze the environmental risk due to the presence of a TPS. Analysis of public opinion and the behavior of people will use a questionnaire in the collection of data to be analyzed with qualitative methods as a consideration in determining the location and design of a TPS. Institutional aspect will be evaluated about the understanding DKP (Office of Cleaning and Gardening Services) employees of the City of Denpasar in the management of garbage, especially in the TPS. As for determining the direction and strategy of the management of garbage SWOT analysis was used.Based on the analysis, the need for the addition of TPS to improve the capacity of TPS, the shape of TPS had comply standard of SNI and environmental safety factor. Additions and changes in the shape of TPS also effect land requirement, the total area of land that must be reserved for TPS is 0,40 hectares. Determining the location of TPS is based on the need of the type of TPS over the spatial pattern. Analysis of public opinion on the determination of the location of TPS, it is obtained that the distance of a TPS with the source must be relatively close and the land use is a vacant land. It is also suggested optimizing the role of the DKP of Denpasar by increasing socialization and community development programs in waste management.

Astronautical mutagenesis is a new and security agricultural breeding technique in recent decades. There are very large differences in physical environment between space and ground. After returning to the ground, new varieties are bred by the conventional breeding techniques. There are rich genetic types in mutagenesis. In this paper, “Longmu 801” alfalfa seeds were carried by “Shijian-8” recoverable satellite and some new types were selected and bred. The genetic variation of 11 mutated lines and their CK were identified by RAPD analysis, determination of leaf protein concentrates (LPC) and crude protein. For genetic identification, 100 primers were tested and 19 primers were selected in RAPD amplification. The amplified bands and polymorphic sites were rich. Polymorphism points and ratios of polymorphism point were statistical in detail. They were 326 and 15.04% respectively. For quality identification, it was compared with yields of alfalfa LPC and crude protein contents. The results showed that the range of yields of LPC was 6.52%-7.65%, range of nitrogen content was 43.79%-52.38%. Comparing with CK, variation ranges were -3.99%-+12.99% and -4.45%-+12.49%.

Analytical limitations have constrained the determination of nanopollution character from real-world sources such as nano-enabled products (NEPs), thus hindering the development of environmental safety guidelines for engineered nanomaterials (ENMs). This study examined the properties of ENMs in 18 commercial products: sunscreens, personal care products, clothing, and paints—products exhibiting medium to a high potential for environmental nanopollution. It was found that 17 of the products contained ENMs; 9, 3, 3, and 2 were incorporated with nTiO2, nAg, binaries of nZnO + nTiO2, and nTiO2 + nAg, respectively. Commonly, the nTiO2 were elongated or angular, whereas nAg and nZnO were near-spherical and angular in morphology, respectively. The size ranges (width × length) were 7–48 × 14–200, 34–35 × 37–38, and 18–28 nm for nTiO2, nZnO, and nAg respectively. All ENMs were negatively charged. The total concentration of Ti, Zn, and Ag in the NEPs were 2.3 × 10−4–4.3%, 3.4–4.3%, and 1.0 × 10−4–11.3 × 10−3%, respectively. The study determined some key ENM characteristics required for environmental risk assessment; however, challenges persist regarding the accurate determination of the concentration in NEPs. Overall, the study confirmed NEPs as actual sources of nanopollution; hence, scenario-specific efforts are recommended to quantify their loads into water resources.

The Arctic is of great importance for the development of the country’s economy. At the same time, the active entry of industry into this region brings with it environmental risks. The most difficult issues for reducing environmental stress in this zone are the elimination of accumulated environmental damage, prevention and elimination of accidents. The important decisions made in the development of the Arctic provide for the implementation of environmental protection measures based on the national project “Ecology”. Large industrial enterprises located in the Arctic will play a significant role in this. To ensure conditions for the further development of the economy in this zone, it is necessary to intensify the work on cleaning up the contaminated areas, including the completion of a project for the ecological improvement of the Franz Josef Land archipelago. The issue of assessing and eliminating the consequences of accidents is relevant for the Arctic, but in this direction it is necessary to improve the regulatory and methodological base. Based on the results of the study, specific measures are proposed to improve the environmental situation in the Arctic, including: to organize scientific research to assess the accumulated and current and environmental damage in the Arctic, to form a separate subprogram “Elimination of accumulated environmental damage in the Russian Arctic for the period 2022–2030”; to prepare proposals for the allocation of directions in the structure of the Arctic Development Fund for environmental safety and elimination of accumulated and future environmental damage; to develop a modern regulatory and methodological base for the determination of damage; to settle issues of a regulatory and methodological nature in terms of assessment and elimination of the consequences of accidents to develop proposals on the use of public-private partnership mechanisms with state funding of measures aimed at the rehabilitation of environmentally unfavorable territories, the elimination of environmental damage in the Arctic.
