Understanding the behavior of organic compounds in these interfaces can help
assess the identity, distribution, transfer, bioavailability, and environmental risks of
these compounds in the environment. It may also be useful to develop techniques
and/or to choose a technique for changing the distribution and transfer of organic
compounds in these interfaces which will have useful results (Gariazzo et al. 2005).
For example, a plant or microbe with a high capacity to accumulate and degrade
organic compounds can be selected and grown to remediate contaminated soils.
Furthermore, an additive can be added to the contaminated soil to accelerate the
absorption of organic compounds into the soil particles in order to sequester it in the
soil and to reduce their concentration in the soil water and its accumulation by the
roots, which will contribute to greater food safety produced from these plants that
grow on contaminated soils (Beliaeff and Burgeot 2002).
1.2 Environmental Degradation vs. Technological
Development Progression
There have been a number of encouraging trends in environmental protection in the
last decade: greenhouse gas emissions are declining; the share of renewable energy
sources is increasing; certain indicators of air and water pollution show significant
improvements worldwide, although this does not always result in with good air and
water quality; and material use and waste generation, while still growing, are growing at a slower rate than the economy.
A number of environmental issues reflect key features of systemic risk:
• Many of the environmental problems, such as climate.
• Changes and biodiversity loss are related and have a complex and often global
character.
• They are closely related to other challenges, such as the unsustainable use of
resources, which extend to the social and economic sphere and undermine the
services of the ecosystem.
• Environmental problems are becoming more complex and intensified, even
related to social problems, which increases the risks that arise from them.
1.2.1 General Climate Change Issue
The global climate has been extremely stable for the last 10,000 years and has provided the conditions for the development of human civilization, but today there are
clear signs that the climate is changing (Conway et al. 1988). This is widely recognized as one of the most significant challenges facing humanity. Measurements of
global atmospheric greenhouse gas (GHG) concentrations show an evident increase
over the pre-industrial period, with carbon dioxide (CO 2 ) levels well above the natuB. Balabanova
