AI-based recognition systems, and smart security video networks have led to a paradigm shift in the architecture of security video systems.

Thanks to the intervention of Cloud-based tech tools, professionals no longer need to visit their offices to engage in business transactions.

While Amazon Web Services, or AWS, and Microsoft are restructuring some large contracts on a case-by-case basis, according to people familiar with the decisions, smaller companies aren’t receiving the same flexibility.

Small and medium-sized enterprises (SMEs) in India are set to benefit from a $30 million global "anti-COVID" programme that Alibaba Cloud, the data intelligence backbone of Chinese e-commerce giant Alibaba Group, launched on Thursday.

Land-dwelling and charismatic animals, such as birds and mammals, receive greater attention in conservation research than other species. How does this bias affect those that are not so well known or loved? A new study suggests that African species in freshwater habitats may suffer as a result.

How can ecotourism be managed so that tourists' visits are compatible with the protection of species and their habitats? In a new study, researchers developed a tool to calculate the trade-off between tourism and the protection of an endangered bird in an Austrian national park, in order to optimise conservation and visitor management.

Converting grassland to arable land can reduce the diversity of nematodes, predatory mites, earthworms and enchytraeid worms in the soil, according to a study by Dutch researchers. However, they found that restoring arable land to grassland did not fully restore the diversity of these four groups during the course of the four-year study.

Biodiversity experts working in governance and science have called for greater integration of policy sectors, geographical levels and academic disciplines, in a stakeholder workshop. This would help ensure policy decisions realistically reflect complex relationships between ecological and governance processes in order to meet future biodiversity targets.

Species surveys should be standardised across Member State borders to assess conservation status accurately, a new study concludes. The researchers assessed the conservation status of the Eurasian otter across the Republic of Ireland–UK border, finding that it was favourable for the whole island of Ireland. This provides a case study of surveys designed to provide data that is comparable across borders, say the researchers.

Small mammals clearly benefit from a UK agri-environment scheme (AES), a recent study concludes. Numbers and diversity of voles, shrews and mice were found to increase on and around farmland with 6 m wide field margins and patches of semi-natural habitat - features encouraged under the government-led AES.

With over half of Europe’s species dependent on agricultural habitats, protecting ‘high nature value’ farmland is vital to biodiversity conservation. However, the identification and assessment of such farmland requires careful co-ordination, concludes a recent study. The researchers present a framework to help with this process and make a set of key recommendations.

Only about two or three small birds are killed by wind turbines each year for every 225-300 houses supplied with renewable energy, new research suggests. The study collated data from 116 US and Canadian studies on 156 species of passerines (small birds). The study suggests some species are affected more than others, but that wind turbines generally have only a minor impact on these small-bird populations.

Assessing threats to biodiversity is necessary for effective spatial planning and balancing sustainable development with conservation. This study details a fine-scale assessment of the effect of a range of threats to coastline habitats within a Marine Protected Area (MPA) in the Mediterranean Sea. The study provides an example of how local-scale assessments can contribute to national conservation policy.

Natura 2000 sites have, on average, 10% more carbon in their topsoil than non-protected areas, according to new research. They also generally have lower economic value for agriculture. The results suggest that there is significant potential to develop win-win biodiversity conservation and climate change mitigation efforts within the EU.

This study is one of few to assess the genetic diversity of crops in an agroecosystem over several years. Researchers analysed the genetic makeup of oilseed rape plants within and outside crop fields over four years. They found similarity between cultivars of field plants in one year and those of feral plants (unplanted) in the following year. They also found persistence of the cultivars within the feral plants, which suggests that feral populations with genetically modified (GM) traits might result from persistent GM traits within field seed banks. The researchers say their findings could aid impact assessments of GM crops.

Invasive alien species (IAS) pose a threat to native European biodiversity and cost the EU annual damages worth EUR 12 billion as a result of IAS effects on human health, damaged infrastructure, and agricultural losses. IAS are the focus of Target 9 of the Convention of Biological Diversity (CBD) and Target 5 of the EU Biodiversity Strategy: ‘By 2020, IAS and their pathways are identified and prioritised… pathways are managed to prevent the introduction and establishment of new IAS.’ The EU framework for action against IAS is set out in a Regulation adopted in 2014. This provides for the adoption of a list of IAS of Union concern that will be subject to restrictions across the EU. The first step in order to consider a species for listing is to undertake a risk assessment.

Almost a quarter of the world’s non-polar land surface experiences light pollution, and there is concern that this adversely affects illuminated ecosystems. Currently there is a global move from yellow sodium lighting to white LED lighting, which emits different wavelengths of light. A recent study found that LED artificial light at night (ALAN) reduced the biomass of periphyton by 62% in a freshwater drainage ditch in Westhavelland Nature Park, Brandenburg, Germany.

New research has supported a more thorough integration of toxic mixture assessments into two major pieces of EU legislation: REACH and the Water Framework Directive. It recommended constructing a database of harmful chemicals in the environment which, among other uses, could assess mixture toxicity using a 'Concentration Addition' method.

Comparative toxic assessments across regions and countries are needed to minimise human exposure to harmful chemicals associated with consumer products. A new study has developed a US version of the EU Toxic Potential Indicator (TPI) and compared the two models for over 500 chemicals. Differences in results exist, indicating a need for more harmonisation between regulatory thresholds and guidelines.

Applying a low voltage to polluted river sediment can boost microbes’ natural ability to degrade harmful polychlorinated biphenyl (PCB) contaminants, according to a new study. The approach could be a cost-effective, sustainable strategy to bioremediate polluted sites.

Recent research has found that silver nanoparticles in sewage sludge, which is used on agricultural land as a fertiliser, can be toxic to soil microorganisms. The researchers calculated that a maximum of 30mg of silver nanoparticles per kilogram of sludge can be applied to land before harm occurs, based on typical application rates in Germany of five tons per hectare of farmland every three years.

A risk-based tool built using multi-criteria decision analysis has been developed to rank environmental contaminants, giving each a level of concern. It can be used by decision makers to prioritise areas for further assessments, based on expected human health impacts.

Fish fed polystyrene nanoparticles are less active and show changes to their brains and metabolism, according to a study by Swedish and Danish researchers. The findings suggest that nanoparticles in the environment could have a major impact on fish and aquatic ecosystems.

Environmental risk assessment is challenging because of the complexity of the physical and ecological systems around us. Natural disasters, the spread of dangerous substances, ecosystem changes leading to food and health security issues, and the emergence of new materials, new events and new knowledge make it essential to update our understanding continually, to be able to identify threats and opportunities for timely action. This Thematic Issue presents some collaborative and integrated paths towards forward-thinking assessment and management of environmental risks.

New research has combined two different techniques for identifying hazards and assessing risks into a single dynamic risk assessment process. The new approach fills a gap in many current risk assessment techniques as it can be applied throughout the lifetime of a process, not just during its design phase, taking into account new information to update risk assessments and calculations systematically.

A methodology for assessing ‘chemical footprints’ has been developed by researchers to evaluate human pressures and the impact of chemicals released by the production and consumption of goods. The study integrates a life-cycle approach with different methodologies, such as those developed in the context of environmental risk assessment and sustainability science, with the aim of assessing the extent to which chemicals impact on ecosystems beyond their ability to recover (i.e. surpass planetary boundaries).

Chemicals regulation in Europe could be improved through integrated risk assessment, says an EU project. The project team presents a range of perspectives on how the integration of hazard, exposure and socio-economic assessments can be promoted and implemented.

Lithium production has increased dramatically during the past decade. A new study has found that exposure of rainbow trout to lithium results in fast accumulation in plasma and the brain, along with decreased concentrations of ions such as sodium.

To assess the risk posed by metals in the aquatic environment, Biotic Ligand Models (BLMs) were developed, and are now considered suitable for use in regulatory risk assessments. This study reviews the advantages of BLMs and BLM-based software tools, providing examples from across the EU, and offers recommendations for their widespread implementation.

The use of two methods to systematise evidence-evaluation methods is reviewed in nine EU regulations dealing with chemicals risk assessment. The majority of frameworks were found to promote the use of ‘weight of evidence’ or ‘systematic review’-style approaches, but the study found a lack of structured, consistent and detailed guidance for these approaches. The researchers recommend this guidance is developed collaboratively by European regulatory agencies and points to best practice for this guidance.

Pollutants have been shown to alter the structure of bacterial communities in the coastal waters around the Alang-Sosiya shipbreaking yard in north-west India. The research analysed seawater from two sites near Alang-Sosiya and from pristine sea water taken 10 km from the coast. The results provide a clearer idea of changes to the microbial ecology near a large ship recycling yard.

Nanotechnology is a key enabling technology predicted to have many societal benefits, but there are also concerns about its risks to the environment. This study reviewed the effects of nanoparticles on soil microorganisms, showing that toxicity depends on the type of particle. The researchers make recommendations for improving environmental risk assessment, including performing experiments in soil and over longer time periods.

Chemicals are everywhere and new substances are regularly being introduced to the market. However, only some pose a risk to the environment. How do we decide which of them to monitor? A new study using a database of chemicals found in fish in the Baltic Sea has assessed which chemicals are commonly monitored. The researchers suggest that monitoring is biased towards known, already regulated hazardous chemicals, and recommend changes to address other chemicals.

A method for developing ecological scenarios for assessing pesticides’ risks to aquatic wildlife has been developed. It is based on the selection of vulnerable taxa according to biological trait information, exposure conditions and environmental properties. The method should help decision makers define what to include in ecological models used for future pesticide risk assessments and is proposed as a way to increase the ecological realism of pesticide risk assessment.

A recent study has evaluated frameworks and tools used in Europe to assess the potential health and environmental risks of manufactured nanomaterials. The study identifies a trend towards tools that provide protocols for conducting experiments, which enable more flexible and efficient hazard testing. Among its conclusions, however, it notes that no existing frameworks meet all the study’s evaluation criteria and calls for a new, more comprehensive framework.

Judging whether to replace a hazardous conventional chemical in a product with a nanomaterial — i.e. to assess which is the safer alternative — is challenging for many reasons. A new study suggests that chemical-alternative assessment frameworks could be adapted to better assess engineered nanomaterials with the help of new tools which provide data on hazards of, and exposure to, nanomaterials.

Evaluating the level of danger to human health from exposure to multiple chemicals in contaminated sites is a complex task. To address this difficulty, researchers have developed a new screening tool that can be incorporated into public health risk assessment, which may include polluted former industrial plants, waste dumps, or even land where pesticides have been used. This ‘hazard index’ approach indicates when risk to health is high, which organs are most affected, and where further evaluation should be conducted in the context of environmental or occupational exposure at such sites.

According to most EU legislation, regulatory assessment of chemicals should make use of all available and relevant studies. However, in practice, assessments tend to be predominantly based on research sponsored and provided by industry as part of their legal obligations to show safety of their products, rather than on independent peer-reviewed findings. To bridge this science–policy gap, a team of Swedish researchers, in combination with regulators at three Swedish governmental agencies, have published a list of recommendations aimed at increasing the regulatory usability and impact of academic research. This advice is aimed at researchers, for whom it clarifies relevant regulatory data requirements and quality criteria. However, it is also relevant to policymakers, in that it highlights the advantages and availability of relevant, reliable peer-reviewed research for use in the regulatory assessment of chemicals. The study’s recommendations contribute to the formulation of more science-based, sustainable policies.

Environmental pollution is putting amphibians and reptiles at risk, yet these animals are not included in regulations regarding the environmental risk assessment (ERA) of pesticides. The extent to which other species already used in pesticide toxicity assessment (including fish, birds and mammals) can serve as effective surrogates is currently under debate. This study conducts a systematic review of the available literature. The results reveal a positive correlation between toxicity recorded on fish and aquatic amphibians, but indicate that birds and mammals are generally not good surrogates for reptiles and terrestrial amphibians. Moreover, some chemical-dependent trends were detected, with a number of insecticides found to be more toxic to amphibians or reptiles than to potential surrogates. These findings highlight an urgent need for further research to reduce uncertainties and contribute to future policymaking regarding the protection of amphibians and reptiles from potentially harmful pesticides.

Silver nanoparticles present in the effluent from waste-water treatment plants could have toxic effects on aquatic organisms, new research suggests. The lab-based study tested the effects of nanoparticle-containing effluent on several crustacean and algae species. The researchers observed that epibenthic crustaceans (those living in or on sediments at the bottom of water bodies) were the most sensitive; notably, a 20–45% higher death rate was observed compared with those exposed to nanoparticle-free effluent.

Despite some criticisms about the Clean Development Mechanism (CDM), a new study has indicated that CDM projects in China could be making sizeable improvements to air quality. The research predicted, in particular, that the projects' associated SO2 reductions would make up 13-14 per cent of the reductions in 2010 towards the national target level.

Croatian researchers have developed new indicators that can be used to analyse photochemical pollution and smog caused by ozone. The indicators are based on simple mathematical formulae and could make it easier for those who monitor pollution levels to make meaningful comparisons between different sites.

A new study has compared treatments to reduce odour from wastewater treatment plants, and has suggested that biotrickling filtration and activated sludge diffusion are the two most promising technologies. These appear to perform best on a combination of environmental, economic and social indicators.

Using hydrogen as an energy carrier can help reduce air pollution and greenhouse gas (GHG) emissions associated with fossil fuels, according to recent research. However, if used on a large-scale, it is important that hydrogen does not leak significantly into the atmosphere as it might have some negative environmental effects, such as increasing the lifetime of methane, increasing climate effects and causing some depletion of the ozone layer.

Increased black smoke pollution was associated with increased mortality rates almost a month after exposure in a recent study. The researchers studied death rates in relation to pollution concentrations over a 22-year period in the city of Glasgow, UK, and found significantly higher mortality rates among residents at 13-18 and 19-24 days after increased exposure to black smoke.

Citizen scientists have helped to map pollution across the Netherlands using their smartphones. Their results, produced by thousands of volunteers, are presented in a study which shows how a combination of mass participation and smartphone technology can be a powerful approach to environmental monitoring.

The chances of a child developing Autism Spectrum Disorder (ASD) are higher if the mother is exposed to high levels of fine particulate air pollution during pregnancy, a recent study suggests. This increased risk was associated specifically with exposure in the last three months of pregnancy, the researchers found.

Health impact assessments (HIAs) provide information on the potential health impacts of policies, and are important for developing regulation on air pollution. In this study, researchers evaluated the metrics currently used in air quality HIAs to provide recommendations for their use in policy.
