“…The tested larvae were captured from their wild habitats, mainly from decayed wood stumps, and bred using a commercially available larval substrate, namely the fermented product of dust wood, leaves and soil. For information regarding an overall larva’s handling process and life span, please refer to Shen et al [ 19 ]. The spiked chemicals, namely PCP, PAHs and DLN, were purchased from Sigma-Aldrich, Inc. A 2 mm screen sieved, silt-clay soil separately spiked with PCP, 2 PAHs and DLN at concentrations of 5000, 70,000 and 200 mg/kg-soil, respectively, was mixed in a tumbler for 2 days before use.…”

“…Due to its pest nature, insecticidal compounds, including 22-hydroxyhopane from Adiantum latifolium , have been used in its population control [ 17 ]. On the other hand, two potential roles regarding O. rhinoceros have been reported: one was as the nutritional source of protein [ 18 ] and the other as the bioreactor for pollutant’s decontamination [ 19 ]. In either case, precautions of stopping the larva from escaping need to be known.…”

The potential use of invertebrates as bioreactors to treat environmental pollutants is promising and of great interest. Three types of the persistent organic pollutants (POPs), namely pentachlorophenol (PCP), PAHs (naphthalene and phenanthrene) and dieldrin (DLN), were spiked in soil and treated by using Oryctes rhinoceros larvae, a known pest of coconut trees in southeast Asia, and also the indicators of POP toxicity and the fate and degradability of the ingested POPs were assessed. The larvae were tested at various levels of the POPs and went through an acclimation process. Without acclimation, the tolerance limits of the larvae toward PCP, PAHs and DLN were 200, 100 and 0.1 mg/kg-soil, respectively, yet with acclimation, the tolerance levels increased to 800, 400 and 0.5 mg/kg-soil, respectively. Biodegradation rates of all the tested POPs were >90% by week 2, with <5% and nearly 0% remaining in the feces and body of the larvae, respectively. The results suggest that the use of the beetle larvae in soil POP decontamination is doable.

“…To determine the TPHd level in the water, a 2-mL water sample was extracted using hexane and subsequent centrifugation (company, model) at 10,000 rpm; the centrate was collected and prepared using the internal standard (i.e., 2,4,6-tribromophenol) to qualify its TPH content in a gas chromatography (GC)-mass spectrometry (OP2020 Shimadzu) machine equipped with a Shimadzu Rtx-5MS column. For details of the GC analysis procedure, please refer to Shen et al [17].…”

Conventional pump-and-treat strategies for dealing with groundwater contamination are both energy- and time-consuming. Potential passive biological techniques are of interest to remedy the massive volume of total petroleum hydrocarbon (TPH)-contaminated groundwater worldwide. In this study, novel biopellets made of TPH-acclimated microbes, fermented fruit peel materials, and CaO2 recycled from eggshells were manufactured to treat TPH-contaminated groundwater. The biopellets provided 56 mg of oxygen and achieved a C:N:P ratio by weight of 10:4:1. Moreover, each biopellet was capped with alginate to prolong its floating time in water to 25 days. The mimicked groundwater spiked with 500 mg/L diesel TPHs (TPHd) was treated using our novelly manufactured biopellets. After 8 days of treatment, results showed a 98.8% removal of spiked TPHd at a rate of 64.1 mg/L per day, with a microbial count that increased from nearly zero to 1.0 × 107 CFU/mL. The residual TPHd constituents were mainly C13–C18. Furthermore, microbial consumption of N, P, and oxygen was noted during the 8-day period of TPHd removal. As the TPHd level increased to 1500 mg/L, the removal rate reached 45 mg/L per day, and all TPHd had been removed after 22 days.

“…[2][3][4] Generally, traditional treatment methods for the environmental pollutants can be divided into three categories, including the physical cleaning, [5,6] chemical reaction [7] and biodegradation. [8] The physical method is composed of the separation and recovery of diesel pollutants, however it is difficult to achieve a complete clean. The chemical method is usually conducted on the tackling of diesel pollutants by chemical treatment.…”

A Ternary Photocatalyst with Double Heterojunctionsfor Efficient Diesel Oil Degradation

et al. 2021

The photodegradation is a potential technology to solve environmental issues such as the diesel oil pollution. The titanium dioxide/graphitic carbon nitride (TiO 2 /g-C 3 N 4 ) photocatalyst is widely used for the photodegradation of pollutants. However, the performances of this binary photocatalyst such as the degradation efficiency and cyclic stability are still unsatisfactory for real applications. In our work, we introduce a ptype NiO semiconductor into the binary TiO 2 /g-C 3 N 4 (98: 2) photocatalyst by a simple dipping method. The NiO semiconductor can form double heterojunctions with the TiO 2 and g-C 3 N 4 (dual Z-scheme and Z-scheme + p-n), which can accelerate the separation of photo-generated electron-hole pairs effectively. Thus, the as-obtained ternary TiO 2 /NiO/g-C 3 N 4 (TCN) sample delivers a good photocatalytic performance for diesel oil degradation under a simulated sunlight. Specifically, the TCN (7 : 3) photocatalyst exhibits a 98.94 % degradation efficiency after 2 h of visible-light, largely outperforming the single-component photocatalysts (TiO 2 , g-C 3 N 4 , NiO,) and the binary TiO 2 /g-C 3 N 4 (98 : 2) photocatalyst. The free radical capture test manifests that �O À 2 is the major factor on the degradation. This work presents a typical example to boost the photodegradation performance via a ternary catalyst design, which will provide valuable insight for the future high-performance diesel oil degradation.
