ClearPhytoremediation Mechanism for Emerging Pollutants : A Review
This review covers how plants can be used to clean up emerging pollutants, including microplastics, pharmaceuticals, and personal care product chemicals from contaminated soil and water. Plants absorb these pollutants through their roots and either break them down or store them in their tissues. Phytoremediation offers a cost-effective and environmentally friendly strategy for addressing the growing problem of emerging contaminants in the environment.
Microplastic Ingestion in Aquatic Animals in South East Asia
This review examined microplastic ingestion by aquatic animals across Southeast Asia, documenting widespread contamination from environmental breakdown and waste imports, and surveyed physical, chemical, and biological remediation technologies for reducing microplastic concentrations in water.
Comparison of Microplastic Pollution in Beach Sediment and Seawater at UNESCO Can Gio Mangrove Biosphere Reserve
Microplastic concentrations in beach sand and seawater were compared across sites in the UNESCO Can Gio Mangrove Biosphere Reserve in Vietnam, with higher concentrations in sediments near boat traffic corridors and tourist areas, confirming that even protected biosphere reserves are contaminated and that local human activity drives spatial distribution patterns.
Unraveling microplastic pollution patterns in sediments of a river system: The combined impacts of seasonal changes and waterway differences
Microplastic concentrations in Saigon River and tributary sediments ranged from 140 to 1,200 items/kg, with fiber particles dominant; rainy season flows from tributaries elevated microplastic levels, while the main river showed more dilution effects.
Investigating the Correlation of Microplastic Pollution Between Seawater and Marine Salt Using Micro-Raman Spectroscopy
Micro-Raman spectroscopy was used to investigate the correlation between microplastic contamination in seawater and marine salt from the same source waters, finding that the polymer profiles of microplastics in salt broadly reflect those in the seawater from which the salt was produced.
Application of fluorescent microscopy and Fourier-transform infrared spectroscopy for analysis of microplastics in Can Gio seawater
Researchers validated the combined use of fluorescent microscopy and Fourier-transform infrared spectroscopy for detecting and identifying microplastics in marine environmental samples. The dual-technique approach improved detection sensitivity and chemical identification accuracy compared to either method used alone.
A DPSIR Assessment on Ecosystem Services Challenges in the Mekong Delta, Vietnam: Coping with the Impacts of Sand Mining
Researchers applied the DPSIR (Driver-Pressure-State-Impact-Response) framework to assess the ecosystem services challenges posed by intensive sand mining in the Mekong Delta, Vietnam. The analysis identified urbanisation-driven sand demand as the primary driver, with the resulting river bed incision and sediment deficit threatening delta biodiversity, agricultural productivity, and coastal stability.
Application of fluorescent microscopy and Fourier-transform infrared spectroscopy for analysis of microplastics in Can Gio seawater
Researchers validated a dual-method approach combining Nile Red fluorescence microscopy with infrared spectroscopy to detect microplastics in seawater, achieving recoveries of 88-97% across five plastic types. Applying the method to 27 samples from Can Gio Sea near Ho Chi Minh City, Vietnam, they found polyethylene and PET were the most abundant plastics — contributing new data from an understudied coastal region of Southeast Asia.
A Regional Approach For Health Risk Assessment of Toxicants in Plastic Food Containers
A study in Vietnam assessed health risks from chemical exposure through plastic food containers, surveying 309 people and testing 59 samples. Researchers found that many containers leached hazardous chemicals at levels that posed a potential health risk, especially for children. The findings highlight the need for stricter regulations on plastic food packaging in developing countries.
The impacts of some plant protection chemical OCPs on two crustacean species \(\textit{Daphnia magna}\) and \(\textit{Moina macrocopa}\)
Researchers evaluated the acute toxicity of the organochlorine pesticides DDT, alpha-chlordane, and gamma-chlordane on two crustacean species, Daphnia magna and Moina macrocopa, measuring 24-hour and 48-hour LC50 values. Results showed that D. magna had a 24-hour LC50 of 20.8 µg/L and M. macrocopa 13.5 µg/L for DDT, with values decreasing substantially after 48 hours, indicating time-dependent toxicity and species-level differences in sensitivity.
Assessing Microplastic Prevalence and Dispersion from Saigon Urban Canals via Can Gio Mangrove Reserve to East Sea by Raman Scattering Microscopy
Researchers used Raman scattering microscopy to assess microplastic prevalence and dispersion along a transect from Saigon urban canals through the Can Gio Mangrove Reserve to the East Sea, characterizing how urban plastic pollution travels through mangrove ecosystems into coastal marine waters.
Assessing microplastic dispersion from Saigon urban canals via Can Gio Mangrove Reserve to East Sea in Vietnam by Raman scattering microscopy
Researchers used Raman microscopy to trace microplastics from Ho Chi Minh City urban canals through the Can Gio Mangrove Reserve to the East Sea, detecting common polymers including PE, PET, PA, PP, PVC, PS, and PMMA throughout. The study demonstrates how urban plastic waste can travel from inland waterways into coastal and marine ecosystems in Vietnam.
Assessing microplastic dispersion from Saigon urban canals via Can Gio Mangrove Reserve to East Sea in Vietnam by Raman scattering microscopy
This study traced the movement of microplastics from urban canals in Ho Chi Minh City through the Can Gio Mangrove Reserve to the East Sea using Raman scattering microscopy. Results confirmed that urban plastic pollution is transported through mangrove-lined coastal waterways to the open ocean.
