Project Details Environmental Chemistry - Development of Three Technical Symposia at the 46th IUPAC Congress, Sao Paulo 2017

Project No.:
Start Date:
13 March 2017
End Date:
02 May 2018


The project aim is to coordinate and organize three symposia to be included in the ‘Energy, Water and Environmental Science’ theme in the 46th IUPAC World Chemistry Congress 2017 in São Paulo and to organize the best Environmental Chemistry Poster competition.

The symposia proposed are: (Symposia ‘EE’ or 5 in the Congress program)
5.10 E-waste – an emerging global environmental challenge and
—– Global Environmental Challenges of Nanomaterials
5.9. Fate of Pesticides in Latin American Environments

These symposia will enable scientific and professional exchange related to themes and topics associated with the work and expertise of Division VI membership.


The scientific program for the Sao Paulo 2017 IUPAC congress has recognized the importance of the link between chemistry and the environment. The proposed symposia contribute towards the ‘Energy, Water and Environmental Science’ theme and include topics that are relevant to the work and expertise located in the IUPAC Division on Chemistry and the Environment (Div VI).

The Division sponsors a number of active projects focused on issues related to industrial activities, agriculture, and naturally occurring materials of toxicological significance as well as aspects of environmental monitoring, environmental risk assessment and chemical aspects of remediation technology and can bring as invited lecturers a series of project team leaders and members representing several of these projects from a variety of countries. It is therefore proposed that the Division coordinates and organizes 3 symposia to be in included under the ‘Energy, Water and Environmental Science’ theme and the environmental impact of emerging technologies and the fate of pollutants in the environment.

• E-waste – an emerging global environmental challengecoordinator: Diane Purchase
E-wastes contain potential contaminants that are distinct from other forms of wastes; there is a paucity of information on their long-term impact and management strategy. This section of the symposium aims to:

a. disseminate the findings from the IUPAC funded e-waste project;
b. bring together global expertise to exchange the latest research on the chemical analysis of e-waste, their environmental and health impact and related risks, and treatment and recycling of e-waste; and
c. provide recommendations on how to tackle this 21st century global environmental challenge.

• Global Environmental Challenges of Nanomaterialscoordinator: Sherine Obare
New trends in the determination of contaminants in various environmental compartments – new analytical methods for emerging pollutants, monitoring emerging pollutants in the environment; Bioavailability and risk assessment – bioavailability and risk assessment of emerging pollutants, risk of contaminants of emerging concerns
Reducing the environmental impact – alternative environmental-friendly technologies, alternative solvents, new technologies for soil/water remediation; Increased usage of nanoparticles in industrial processes as well as in commercial products continues to raise global concerns about their adverse impact on the environment and on human health.

The symposium will focus on reporting the most recent strategies that have resulted in systematic methods to develop an understanding of the toxicity, bioavailability, and environmental fate and transport of nanoparticles. It will also focus on studies that advance our understanding of the environmental health and safety concerns of nanoparticles relative to their method of preparation and their properties that arise as a result of preparation techniques. The symposium will be of particular importance to:
1. Regulatory agencies including government and research laboratories concerned with the risks of nanoparticle disposal and exposure.
2. Chemical industries that use and/or manufacture nanoparticles.
3. Toxicology, ecological risk assessment and health groups aiming to understand the behavior and impact of nanoparticles in the environment.

• Fate of Pesticides in Latin American Environmentscoordinator: John Unsworth
Agriculture is an important industry in Latin America with a correspondingly significant use of pesticides. As the world population increases towards the predicted 9 billion in 2050 it is essential that there is an increase in food production, with a subsequent increase in the use of pesticides to minimize crop losses particularly, for Latin America, on export crops such as cotton, bananas, plantains and pineapples. Export of agricultural products is a major source of income today for some Latin American countries and is likely to remain or become more important in the coming years. It is important that the pesticides used do not pose a risk to human health and the environment. The symposium will focus on the fate of commonly used pesticides in Latin America, general and local models for environmental risk assessment and means of minimizing or mitigating risk in using pesticides. The symposium will be of particular interest to:
1. government regulatory officials
2. industry scientists involved in safety studies for chemicals, including pesticides
3. academics and students involved in studies on environmental impact of chemicals, including pesticides


July 2017 update – As part of the symposia series presented by Division VI (Chemistry and the Environment) in the IUPAC 46th World Chemistry Congress, Sao Paulo, Brazil, the task group has organised a symposium on ‘Environmental impact of emerging technologies: E-waste- an emerging global challenge’. Our panel of international speakers explored a number of issues, including: management and regulations of electronic waste in developed and developing countries, the resulting environmental and health impacts, development of a sustainable alternative electronic component and valorisation of electronic waste. The abstracts and photos of the e-waste symposium can be access via these links.

May 2018 update – A report covering the 3 symposia is published in Chem Int Apr 2018, pp. 46-51 <>.
