The potential for phosphorus (P) recovery from various sources in Southern Vietnam has been assessed in this study. Five types of waste were studied, namely sediment from catfish pond, manure from cattle and pig farming, and also sludge from domestic and rubber-latex processing wastewater-treatment plants. The study identifies P-reserve and assesses factors related to P recovery from waste sources such as distribution, collection, transportation conditions, and composition of wastes. P-reserve from catfish farming is estimated about 17.7 kt yr-1 while reserve from pig farming is the highest, about 21.7 kt yr-1. Total P-reserves from studied wastes are estimated about 50 kt yr-1, equivalent to 37% of Vietnam’s imported nutrient P quantity in 2019. Generated sludge from rubber-latex processing wastewater-treatment plants has the highest potential and favorable properties for P recovery. It turns out to be feasible to collect and recover P from this waste source under Vietnam’s current conditions.

“…Heavy metals in contaminated soils can be accumulated by earthworms, simulating the effects of vital substances in the body and resulting in illness (Seribekkyzy et al, 2022). Earthworms have a tremendous potential for rehabilitating soil that has been contaminated with heavy metals (Sizmur and Hodson, 2009;Ahadi et al, 2020;Yuvaraj et al, 2020).…”

Heavy metals are a serious problem that caused several health problems in humans and animals. They also affect the diversity of soil fauna as well as the environment. The proper management of heavy metal concentrations can be managed by the inoculation of earthworms in their habitats. Through bioaccumulation of heavy metals in their body, earthworms reduce the toxic level of heavy metal concentration. Lampito mauritii is common earthworm species that accumulate heavy metals in its body tissues. Heavy metal concentration was observed in different animal dung with municipal solid waste (MSW) and final vermicompost as well as in earthworm bodies. A significant decrease in heavy metals concentration such as cobalt (Co), chromium (Cr), lead (Pb), nickel (Ni), and cadmium (Cd) was observed in all the combinations of different animal dung with MSW after vermicomposting by earthworm Lampito mauritii. A significant reduction of cobalt (Co) was observed in the vermicomposts obtained from buffalo dung, whereas cow dung only has a significant maximum reduction in the level of chromium (Cr) (91.48%, 0.072 ± 0.002 mg/kg). The maximum reduction of lead (Pb) concentration was observed in the vermicomposts obtained from the combination of buffalo dung with municipal solid waste in the ratio (1:1) (96.61%, 0.060 ± 0.003 mg/kg). There was a significant decrease in the concentration of nickel (Ni) in vermicomposts of all combinations of animal dung with municipal solid wastes. Whereas, the concentration of cadmium (Cd) is significantly reduced in the vermicomposts obtained from goat dung (95.62%, 0.017 ± 0.005 mg/kg). The result of this study clearly illustrated that during vermic-activity, Lampito mauritii considerably decreases different heavy metals in the final vermicompost and can act as a biological indicator of soil quality. With the help of this technique, MSW can be managed effectively while also being protected from toxic levels of heavy metal contamination in the human diet.

“…Nonetheless, earthworm abundance and network shape are dependable signs to evaluate soil infection and also can repair infected soil through bioaccumulation [17][18][19][20]. For example, greater probably poisonous factor elimination in earthworm-assisted treatment of municipal wastewater, manure, and different probably poisonous factors-wealthy natural wastes had been reported [21][22][23][24]. However, the systematic evaluation of earthworms' ability to potentially toxify elements and treat infected soils is limited, and only some opinions have been published on the use of earthworms to treat infected soils [25,26].…”

The earthworm is the most beneficial organism for assessing metallic contamination due to the fact that critical high-quality correlations have been determined between earthworm steel concentrations and soil cadmium, copper, lead, zinc, and mercury concentrations. The mercury compounds are very poisonous for most organisms. Here, we investigated the ability of earthworms (Lumbricus terrestris) to HgCl2 (below laboratory conditions). A study of the effect of five different salt concentrations of mercury chloride (HgCl2) 1 ppm, 5 ppm, 10 ppm, 50 ppm, and 100 ppm was studied on worm survival and calculation of the concentration required to destroy half the number of worms (LC50). The results showed that there is an inverse relationship between these salt concentrations and the time required to perish 100% of worms. It was found that the concentration of 100 ppm is the lethal concentration of half the number (LC50) of the earthworm (Lumbricus terrestris). The effects of the salt concentrations used confirmed their effect on the experimental worm weights as well, so the concentration of 50 ppm was the most influential on earthworm weights of the type of Lumbricus terrestris, as it caused a reduction 12% of worm weights with a significant difference, while the concentrations 1 ppm and 100 ppm were the least effective, as they caused the worms to decrease by only (5%), while the remaining two concentrations 5 ppm and 10 ppm caused their effect to decrease by 7% only. Thus, it can be concluded that lower worm weights have nothing to do with the lethal concentrations of the heavy metal salt (HgCl2). The histological study also showed that low concentrations of mercury chloride salt have less effect on earthworms’ skin tissue compared to higher concentrations.
