During International Year of Chemistry 2011, the role chemistry plays in telling us about changes in the world around us is the focus of a seminar at Charles Sturt University (CSU) in Wagga Wagga on Monday 18 July. The seminar, entitled Chemistry in the real world – from nanotechnology to freshwater ecology, will showcase research in chemistry in the University’s School of Agricultural and Wine Sciences. Senior lecturer Dr Paul Prenzler said the study of chemistry helps us to have a better understanding of what is happening in the real world. “Underlying our health as humans and the health of the environment around us are chemical processes that can take place at very small or ‘nano’ levels or large scales, such as water quality in rivers,” he said. The seminar will discuss antioxidants and human health, river and soil health, along with wine colour and quality.
