Pyrrolizidine alkaloids (PAs) and their N-oxides (PANOs) are novel contaminants in tea. However, the source of PA/PANO contamination in tea remains unclear. In this study, 15 PAs/PANOs were extracted from plant samples (tea, fresh tea leaves, and weeds) with 0.1 M sulfuric acid and from soil with...

In today's industrialized world, contamination of soil and water with various substances has emerged as a pressing concern. Bioremediation, with its advantages of degradation or detoxification, non-polluting nature, and cost-effectiveness, has become a promising method due to technological...

Lithium (Li), gallium (Ga) and indium (In) are industry-critical metals, with no known plant species that (hyper)accumulate these metals to any substantial degree. We hypothesised that sodium (Na) hyperaccumulators (i.e., halophytes) may accumulate Li, whilst aluminium (Al) hyperaccumulators may...

In order to explore the relationship and the current situation between the geological background of tea garden and the content of heavy metal elements in tea, the rocks, soil and tea in Mengku tea garden and Jingmai tea garden in Yunnan Province were selected as the research objects. The contents...

Soil acidification is common in some Chinese tea plantations, which seriously affected growth of tea trees. Hence, it is essential to explore soil remediation in acidified tea plantations for sustainable development of the tea industry. We sought to determine how different fertilizers affect...

Purpose: Phytoremediation is a cost-effective and environment-friendly method to remove heavy metals from soils, but there is a bottleneck with the low solubility and bioavailability of metals. To overcome this barrier, tea saponin (Ts) and plant growth-promoting rhizobacteria (PGPR) were used to...

Three kinds of fortifiers, polyaspartic acid (PASP), aminotriacetic acid (NTA), and tea saponin (TS) were applied in strengthening the phytoremediation efficiency of nickel by Bidens pilosa L. (B. pilosa) in nickel-pyrene-contaminated soil. The growth of B. pilosa, Ni distribution in B. pilosa,...

Perfluorobutane sulfonate (PFBS) has been found in increasing concentrations in the environment. However, its effect on litter decomposition in soils is still unclear. Therefore, the effect of PFBS on the decomposition of various litter types was tested, as well as on selected aspects of soil...

To explore the effects of exogenous tea polyphenols on Pb stress in tobacco, a pot experiment was conducted to simulate soil lead (Pb, 750 mg/kg) pollution to study the effects of pouring tea polyphenols (TP, 0, 300, 600, 900 mg/kg) on the key indicators of antioxidation and nitrogen metabolism in...

The pervasive use of pyrethroids is seriously hazardous to the environment and even human health. Enzymatic bioremediation is potentially a rapid and environmentally friendly technology to combat the pollution of pyrethroid pesticides. The hydrolysis of ester linkages is the initial and critical...
