Seminar of ANSO MORATOXA Projet for indoor dust collection strategy

On October 17th 2024, the online seminar of “Monitoring and Risk Assessment of Toxic Chemicals in the Air (MORATOXA)” program supported by ANSO was successfully held online. About eight experts and students attended this seminar, including Dr. Zhao Shizhen from GIGCAS, four students from GIGCAS (William, Kun, Yuwei and Weiru) Dr. Simion Bartilol from the University of Nairobi in Kenya, and two students from the University of Nairobi, to discuss on indoor dust collection strategies.  This seminar was chaired by Dr. Shizhen Zhao.

After Dr. Shizhen and Dr. Simion introducing the participants, they discussed about the difficulties in indoor dust sampling. In order to better support the sampling, Weiru shared the review of collected samples, the basic requirements of household dust sampling and three strategies of dust collection. After discussion, we clarified the follow-up sampling details, and determined the supplies we could provide. This online meeting will lead to further progress in the project.

Weiru’s six-day travel in Malaysia

From August 3 to 8, Wang Weiru visited the University of Malaya  per invitation by Dr. Bong Chui Wei(黄翠薇). This mobility is an element of the Research Project of the Alliance of International Scientific Organization (ANSO) – Monitoring and Risk Assessment of Air Toxicants (MORATOXA). The main goal of the visit was to promote substantial cooperation between the two sides, as well as to bring the air samples, dust samples and hair samples back to Guangzhou the base of the ANSO project. Dr. Bong and her students fully supported Weiru in the collection of the hair samples. They also demonstrated the high quality atmospheric sampling and preservation in Kuala Lumpur which are dedicated to MORATOXA.  At last, a total of 21 air samples (including one field blank), 36 hair samples and 35 house dust samples were retrieved and brought back. The samples are well stored in the fridge now.

During the visit, Weiru was also entertained by Dr. Bong’s students to taste the local food, learn about the local languages and visit the zoo.

It was an efficient and enjoyable visit. We all look forward to further progress on this project soon!

Pilot Study in Futian Mangrove National Nature Reserve

On Jan 8th, a group of us (Shizhen, Jianchu and Weiru) went to Futian mangrove national nature reserve for pilote study. It was the first time that they need to recognize species of trees for sampling. With the help of Dr. Gao from Guangdong Academy Of Forestry, they successfully collected young leaves and old leaves of kandelia candel (秋茄), aegiceras (桐花), bruguiera (木榄) and acanthus ilicifolius (老鼠簕), which are usually found in mangrove forests of coastal areas of Southeast Asia and southern China. Also, they collected one paired of surface water sample and sediment sample as well as two tree ring samples of kandelia cande.

The reason why mangrove is so called “red forest”: Tannins appear red when oxidized.

We were collecting the leaves.
