Macroplastic and microplastic contamination levels were assessed in the Saigon River – a tropical river-estuarine system transverse by Ho Chi Minh city, a megacity with dense population and industrial activities, especially textile and apparel industries. Microplastics were assessed in the Saigon River and in four urban canals by sampling bulk water for anthropogenic fiber analysis and 300-m mesh size plankton net exposition for fragment analysis. Fibers and fragments are highly concentrated in this system, 172,000 to 519,000 items m-3 and 10 to 223 items m-3, respectively. The one year and half monthly survey evidenced that variations of concentrations of anthropogenic fibers were not related to rainfall, water discharge or abiotic factors and the estimated annual emission of anthropogenic fibers from the river to the downstream coastal zone of 115 to 1641012 items yr-1. The analysis of floating debris collected daily on the Nhieu Loc – Thi Nghe canal by the municipal waste management service showed that the plastic mass percentage represents 11% to 43%, and the land-based plastic debris entering the river was estimated from 0.96 to 19.91 g inhabitant-1 d-1, namely 350 to 7,270 g inhabitant-1 yr-1. Floating macroplastics in the Saigon River were assessed by visual counting coupled with trawl net sampling showed that the top 5 floating plastic items found were single used plastics such as PS foam food containers and fragments. A 9-month monitoring campaigned showed that total annual transport 1.4–1.6×103 t/y and there no clear relation between plastic transport and rainfall or annual tidal range variation in the Saigon River.
On 22/10/2015, CARE has organized the meeting of the Scientific Council with the chairmanship of Dr. Nicolas Gratiot - Director and Chairman of the Scientific Council, Assoc. Pro. Vo Le Phu (on behalf of Assoc. Pro. Nguyen Phuoc Dan - Deputy Chairman)
Project description The availability of High Resolution Imagery (spatial, spectral, and radiometric) with an increased time revisit (Landsat-8 and now Sentinel-2) opens the way to a more detailed observation of coastal zones and inland waters (large rivers, lakes and reservoirs)
The pretty work, a monography collection of 15 megacities in the world about "Water, megacities and Global Change”, has been published by UNESCO. The CARE Lab-HCMUT Researchers are honored to represent Ho Chi Minh City by contributing an article
CARE Lab-HCMUT is pleased to present you our publication of the monography "Ho Chi Minh City growing with water-related challenges".
CARE Lab-HCMUT and PADDI, a member of the Ho Chi Minh City delegation, participated in the 26th Environment exhibition POLLUTEC, Lyon (France), which took place from 30/11 to 02/12/2016.
