Metals in China: protecting the environment

20.09.2006
A new international collaborative research project that seeks to protect the environment from metal contaminants will be launched next Monday (18 September) in Beijing, China.

The project will be launched at the Society of Environmental Toxicology and Chemistry Asia/Pacific Conference. It will bring together scientists from CSIRO, the Chinese Academy of Sciences (CAS) and the Chinese Academy of Agricultural Sciences (CAAS), and is sponsored by Rio Tinto, the International Copper Association and the Nickel Producers Environmental Research Association.

Co-Director of the CSIRO Centre for Environmental Contaminants Research, Professor Mike McLaughlin, says the project aims to develop robust scientific guidelines for safe levels of copper and nickel in Chinese soils.

“South-East Asia is booming. Amid rapid industrialisation and expansion of urban populations, we need to ensure the environment is protected,” Professor McLaughlin says.

“Use of metals is increasing. Consider the manufacturing and industrial expansion currently underway in Asia, where the pace of development has outstripped the advancement of relevant policies and regulatory guidelines.

“We need sound local data that builds on recent scientific advances in the understanding of metal behaviour and toxicity in soils.”

In the first instance, a series of field and laboratory experiments will be established for a range of soils and environments in China, to examine the behaviour and toxicity of copper and nickel in Chinese soils.

This data will be combined with data already collected in European Union and Australian research programs, and CSIRO data from other South East Asian countries, to develop models that explain toxicity across a wide range of environments.

Data from previous projects conducted by CSIRO in Malaysia, Thailand and Vietnam has suggested that soils in the region have generally low background metal concentrations, but are very sensitive to metal additions as indicated by effects on plant growth and soil microbial functions,” Professor McLaughlin says.

The cooperation of Australian and Chinese governments and the global metals industries reflects a shared desire to provide science-based metals guidelines in China. The collaboration also recognises the importance of joining local knowledge with global experience in such complex scientific undertakings.

The ongoing scientific research is being endorsed by China's State Environment Protection Agency (SEPA) for guidance on revising metals standards in Chinese soils.

Research in China is being led by Professors Yibing Ma (CAAS) and Yongguan Zhu (CAS) in collaboration with CSIRO.

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Im Focus: Repairing defects in fiber-reinforced plastics more efficiently

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.

Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
