Impact of Nanoparticles on Plants under Drought Stress
Drought is a chronic abiotic stress affecting crop growth and development, accounting for approximately 70% of the potential loss of global crop yield and productivity. Drought hinders agriculture and forestry worldwide, due to very little rainfall or significant differences in moisture. The current trends of global warming are causing a major impact on the moisture levels of the soil and the environment, and are increasing the intensity of droughts. Plants are subjected to various stresses during their growth, and the morphology of plants is affected at all stages of development due to drought stress, with productivity losses expected to reach 30% globally by 2025.

Impact of Particles on Pulmonary Endothelial Cells
Due to particle sizes ranging from the nanometre to the millimetre scale, these particles can be easily inhaled or absorbed by the skin, reaching the cells of the pulmonary alveoli and finally entering the bloodstream, which can lead to health adverse effects. Endothelial cells (ECs) guarantee permeability for the passage of blood, hormone fluids, macromolecules and platelets through arteries, veins, arterioles and venules and controls blood flow and vascular relaxation and constriction. The function of pulmonary endothelial cells (PECs) is not very different from vascular endothelial cells; they regulate blood flow but also control the passage of liquid and macromolecules between the interstitial space, the vessels and the smooth muscle cells.

Impact of the Pandemic and War on Energy
The COVID-19 pandemic and Russia’s war on Ukraine have impacted the global economy, including the energy sector. The pandemic caused drastic fluctuations in energy demand, oil price shocks, disruptions in energy supply chains, and hampered energy investments, while the war left the world with energy price hikes and energy security challenges. The long-term impacts of these crises on low-carbon energy transitions and mitigation of climate change are still uncertain but are slowly emerging. Both crises initially appeared as opportunities for low-carbon energy transitions: the pandemic by showing the extent of lifestyle and behavioral change in a short period and the role of science-based policy advice, and the war by highlighting the need for greater energy diversification and reliance on local, renewable energy sources. However, the early evidence suggests that policymaking worldwide is focused on short-term, seemingly quicker solutions, such as supporting the incumbent energy industry in the post-pandemic era to save the economy and looking for new fossil fuel supply routes for enhancing energy security following the war. As such, the fossil fuel industry may emerge even stronger after these energy crises creating new lock-ins. This implies that the public sentiment against dependency on fossil fuels may end as a lost opportunity to translate into actions toward climate-friendly energy transitions, without ambitious plans for phasing out such fuels altogether.

Impact of Tritium on Living Organisms
Tritium is a byproduct of many radiochemical reactions in the nuclear industry, and its effects on aquatic organisms, particularly low-dose effects, deserve special attention. The low-dose effects of tritium on aquatic microbiota have been intensively studied using luminous marine bacteria as model microorganisms. Low-dose physiological activation has been demonstrated and explained by the signaling role of reactive oxygen species through the “bystander effect” in bacterial suspensions. The activation of microbial functions in natural reservoirs by low tritium concentrations can cause unpredictable changes in food chains and imbalances in the natural equilibrium. The incorporation of tritium from the free form into organically bound compounds mainly occurs in the dark and at a temperature of 25 °C. When tritium is ingested by marine animals, up to 56% of tritium is accumulated in the muscle tissue and up to 36% in the liver. About 50% of tritium in the liver is bound in non-exchangeable forms. Human ingestion of water and food products contaminated with background levels of tritium does not significantly contribute to the total dose load on the human body.

Impacts of Biowaste with Mitigation Efforts in Cities
In many cities, huge quantities of biowaste solid matterials are generated, making it a big challenge to keep our cities smart/clean without creating health issues. The second challenge is to mitigate solid biowastes from municipalities, and it needs systematic valorization/conversion approaches to transform/generate them into clean/least carbon-emitting fuel sources. This effort can help make smart cities with additional amounts of energy generation that can be used by each citizen for their daily energy needs. In the cities, biowastes are reported as food waste (from domestic kitchens and restaurant/hotel), green plant residues (from parks and other cleaning activities), and other miscellaneous sources.

Impacts of Blue Economy on Deep-Sea Ecosystem Services
The deep-sea is the most extensive environment on the Earth and is defined as the water column and seafloor below 200 m water depth. The ecosystem services (E.S.) concept comprises ecological functions (e.g., climatic adaptation) and social and economic values (e.g., food security, job creation) that promote human well-being. Deep-sea E.S. comprise the provisioning of services such as industrial agents and fish catch, regulating services such as climatic and biological regulation, and cultural services such as aesthetics and inspiration for the arts. Several studies have shown that deep-sea ecosystems support a large variety of habitats and a wide array of faunal communities with various functions. These complex communities are threatened by the growth of human activities targeting precisely these provided ecosystem services.

Impacts of Brick Making on Environment
The brick making industry, despite its contribution to environmental pollution, plays a major role in the economic growth of many nations, with the traditional technology accounting for a significant proportion of the total clay brick production. This writeup gives an overview of the origin of brickmaking, its socioeconomic importance, the environmental impacts and improvements made in the art of brickmaking over the years. The environmental impacts from brickmaking cannot be overruled, however, this impacts could be minimized and managed  through the adoption of more sustainable and environmentally friendly firing innovative.

Impacts of COVID-19 on the Aquatic Environment
The COVID-19 pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), resulted in ecological changes of aquatic ecosystems, affected the aquatic food supply chain, and disrupted the socio-economy of global populations. Due to reduced human activities during the pandemic, the aquatic environment was reported to improve its water quality, wild fishery stocks, and biodiversity. However, the sudden surge of plastics and biomedical wastes during the COVID-19 pandemic masked the positive impacts and increased the risks of aquatic pollution, especially microplastics, pharmaceuticals, and disinfectants.

Impacts of Exotic Pests on Forest Ecosystems
Pests (e.g., insects, pathogens) affect forest communities through complex interactions with plants, other animals, and the environment. While the effects of exotic (non-native) pests on trees received broad attention and were extensively studied, fewer studies addressed the ecosystem-level consequences of these effects. Related studies so far mostly only targeted a very few dominant pests (e.g., hemlock woolly adelgid—HWA, beech bark disease—BBD, and spongy moth—SM) and were limited to aspects of the complex situation such as (1) pests’ direct physical disturbance to forest ecosystems, (2) altered geochemical elements of soils, water, and air (e.g., excretion), and (3) feedback effects from the alteration of ecosystems on plants, native insects, and present and future pest invasions. New studies also show that, in general, planted forests appear to be more prone to exotic pest invasions and thus suffer greater impacts than natural forests. Integrated studies are critically needed in the future to address (1) direct/indirect interactions of pests with ecosystem elements, (2) both short- and long-term effects, and (3) feedback effects. The implications of the new findings and corresponding management strategies are discussed.
