“…A contemporary example is genetic engineering for disease resistance, which is now feasible for some pathosystems, and is a technology available in many countries but restricted in Europe. At the same time, tighter rules around chemical pesticides will result in fewer pesticides being available to control many pathogens on crops such as cereals and potatoes [34,35]. The consequence is that disease control in Europe can depend less on technological fixes and must rely more on preventative actions to reduce and contain the risk of disease spread.…”

Plant diseases threaten both food security and the botanical diversity of natural ecosystems. Substantial research effort is focused on pathogen detection and control, with detailed risk management available for many plant diseases. Risk can be assessed using analytical techniques that account for disease pressure both spatially and temporally. We suggest that such technical assessments of disease risk may not provide an adequate guide to the strategies undertaken by growers and government to manage plant disease. Instead, risk-management strategies need to account more fully for intuitive and normative responses that act to balance conflicting interests between stakeholder organizations concerned with plant diseases within the managed and natural environments. Modes of effective engagement between policy makers and stakeholders are explored in the paper, together with an assessment of such engagement in two case studies of contemporary non-indigenous diseases in one food and in one non-food sector. Finally, a model is proposed for greater integration of stakeholders in policy decisions.

“…Various harmful organic compounds have ended up in to the environment since the advent of industrialization. Many anthropogenic compounds in the environment and in food are the focus of interest due to their possible adverse health effects 1–7. Chemical analysis of these compounds is often needed to estimate the risk that they pose to humans and wildlife, and to support decision‐making about protection and legislation.…”

“…Chemical analysis of these compounds is often needed to estimate the risk that they pose to humans and wildlife, and to support decision‐making about protection and legislation. The compounds of interest include, for example, pharmaceuticals,8 components of personal health‐care products,9 pesticides,5 polycyclic aromatic hydrocarbons (PAHs),10 polychlorinated biphenyls (PCBs),6 brominated flame retardants11, 12 and polyfluorinated chemicals 13. The samples to be analyzed are often complex, such as soil, sewage sludge, plant parts, or animal tissue.…”

Desorption atmospheric pressure photoionization-mass spectrometry (DAPPI-MS) is a versatile surface analysis technique for a wide range of analytes, especially for neutral and non-polar analytes. Here, a set of analytes typically found in environmental or food samples was analyzed by DAPPI-MS. The set included five polyaromatic hydrocarbons (PAHs), one N-PAH, one brominated flame retardant, and nine pesticides, which were studied with three different spray solvents: acetone and toluene in positive ion mode, and anisole in negative ion mode. The analytes showed [M + H](+), M(+*), and [M-H](-) ions as well as fragmentation and substitution products. Detection limits for the studied compounds ranged from 30 pg to 1 ng (from 0.14 to 5.6 pmol). To demonstrate the feasibility of the use of DAPPI-MS two authentic samples - a circuit board and orange peel - and a spiked soil sample were analyzed. Tetrabromobisphenol A, imazalil, and PAHs were observed from the three above-mentioned samples, respectively. The method is best suited for rapid screening analysis of environmental or food samples.

“…1). The removal of HCHs and DDTs from soil using natural bioremediation is not an uncommon concept and has been reported in previous studies [32][33][34]. Indeed, indigenous microorganisms in aged contaminated soils are able to metabolize HCHs and DDTs, and some species of microorganisms are able to enhance degradation in soil.…”

Four pilot-scale test mesocosms were conducted for the remediation of organochlorine pesticides (OCPs)-contaminated aged soil. The results indicate that the effects on degradation of hexachlorocyclohexanes (HCHs) and dichlorodiphenyltrichloroethanes (DDTs) were in the following order: nutrients/plant bioaugmentation (81.18 % for HCHs; 85.4 % for DDTs) > nutrients bioaugmentation > plant bioaugmentation > only adding water > control, and nutrients/plant bioaugmentation greatly enhanced the degradation of HCHs (81.18 %) and DDTs (85.4 %). The bacterial community structure, diversity and composition were assessed by 454-pyrosequencing of 16S recombinant RNA (rRNA), whereas the abundance of linA gene was determined by quantitative polymerase chain reaction. Distinct differences in bacterial community composition, structure, and diversity were a function of remediation procedure. Predictability of HCH/DDT degradation in soils was also investigated. A positive correlation between linA gene abundance and the removal ratio of HCHs was indicated by correlation analyses. A similar relationship was also confirmed between the degradation of HCHs/DDTs and the abundance of some assemblages (Gammaproteobacteria and Flavobacteria). Our results offer microbial ecological insight into the degradation of HCHs and DDTs in aged contaminated soil, which is helpful for the intensification of bioremediation through modifying plant-microbe patterns, and cessation of costly and time-consuming assays.
