Nanoparticles are being used in more and more consumer products. They can make materials stronger and lighter and make surfaces cleaner and more wear-resistant. They are increasing the performance of road vehicles, and are increasingly used in medicine to increase the efficacy of medication.
As these products reach their end of life, it will be very difficult to prevent the release of nanoparticles into the environment. As the size of these particles allows them to interact strongly with biological structures, there are all sort of potential human and environmental health issues associated with the build up of nano-waste in ecosystems.
Studying Nanoparticles in the environment
Studies of real nanoparticle concentrations in the environment are few and far between. A Swiss study published in 2010 attempted to model the concentrations of some common types of nanoparticles which end up in the environment. Their results agreed with the limited real-world data which is available.
The study found that the destination of the nanoparticles depends on their usage
Long ago there was a village where there was no disease at all because there was no deforestation. There were many trees and the villagers understood its importance. They lived harmoniously.
One day a woodcutter came to the village. The villagers did not understand what was happening and the woodcutter decided to use this to his advantage. The village did not have a president.
So the wood cutter decided to be the village president and the people accepted him. But then he started to cut the trees there. If anyone opposed him, they would be locked up in jail. So no one opposed him. The village was soon struck by diseases.
Enhancing science in coastal management through understanding its role in the decision making
There is an obvious need for comprehensive interdisciplinary and multidisciplinary research programs that can assist in the management of marine and coastal environments. An ongoing problem is to how to integrate this research into the ongoing development and evaluation of policy and management plans. A large scale systematic research program focused on the Ningaloo Coral Reef and its coastal terrestrial environment has been conducted. Many specific research projects were undertaken varying from bathymetry and fish behaviour to the needs and attitudes of tourists. Over fifty research projects were included. Integration of the findings is being achieved through a series of modelling activities of varying complexity including simple fish population models to a whole-of-system model
This paper provides an understanding of how this research fitted with the overall social system of interaction between decision makers and local stakeholders, and how the information could reach and be made relevant to all roles in regard to the management of Ningaloo. A network approach was developed through interviews and the construction of ego networks. The results of this study revealed clusters of groups that performed particular roles for reef management, and showed that the science cluster demonstrated the characteristics of the
