When major accident scenarios are considered, the effects of major events which give rise to a serious, immediate or deferred danger to human health or the environment, inside or outside the production or storage area due to the presence in high quantities of one or more dangerous substances are being considered. Events of this type, except in exceptional cases, have always had important consequences...

Nanoremediation technologies are based on the injection of reactive nanomaterials into the subsurface to promote in situ degradation of the pollutants. At present, it appears as a valid and very promising alternative to traditional and already established remediation technologies, such as Pump&Treat, In-Situ Chemical Oxidation (ISCO), air sparging and permeable reactive barriers. Due to their small size, nanoparticles (e.g. nanoscale zerovalent iron) presents a high reactivity and can be exploited to generate a reactive zone to treat a wide...

The wide spreading of vertical greening systems brought to the development of new systems and technologies able to improve urban areas quality. Several benefits derive from the installation of these systems: energy savings for air conditioning during summer, thermal comfort improvement indoor and outdoor, urban heat island mitigation, biodiversity increase, protection of building façades with consequent...

Caves are one of the most important and well-known geological features in the world, an environmental and cultural heritage, as well as an important economic resource for many countries. Their scientific and aesthetic value is often threatened by tourism, which unfortunately exposes them to a series of risks of degradation and, sometimes, irreparably changes. Therefore, the study of underground environment...

The objective of this review is to analyse the risks associated with the use of fluids in chainsaws
operations, comparing traditional and eco-friendly materials.
We chose to investigate operations involving the use of portable equipment, particularly those that still use internal combustion engines. Indeed, they pose a high risk to operators due to their proximity to the machine. The scientific literature concerning fuel mixtures and chain oils was studied.
Correlating the examined activities, equipment and machines and their materials,...
