Comparative study on the fraction changes of the Cd immobilized in the soils with simulated acid rain

In-situ passivation is considered safe and effective for moderately and poorly polluted soil, according to a table on remediation of heavy metal pollution in soil. The leached Cd increased and then decreased in a single location and then gradually decreased; AC and CS revealed better passivation capability in HP than in GF soil; and, the addition of CS delivered more CP in HP than in GF soil; and, the oxidized and reduced states of Cd to the residual and oxidized states of Cd to the vaporized states of Cd. According to a comparative analysis, two passivators in GF soil had higher application value than those in HP soil.

Complex effects of different types of acid rain on root growth of Quercus acutissima and Cunninghamia lanceolata saplings

Abstract Background Soil acidification owing to acid rain can damage plant roots, which in turn negatively impacts plant growth. Results As the AR S/N ratio and pH decreased, the height, development rate, total root length, and total root surface area of C. lanceolata decreased, while Q. acutissima's TRL and TRS remained the same, but the TRL and TRS of Q. remained unchanged. When the NO3 u2212 concentration in AR was elevated, the root cause, superoxide dismutase, and catalase activity of C. lanceolata roots showed a downward trend; however, the root of Q. acutissima and the perma enzyme activity of C. lanceolata roots revealed upward trend. Plant root growth was affected by the AR S/N ratio, according to our results. The root systems of many tree species of different tree species had varying responses to AR, and plant root growth was influenced by plant root growth.

Arbuscular mycorrhizal fungi protect a subtropical tree species exposed to simulated acid rain by accelerating photosynthetic ability, antioxidant enzymes and osmolyte accumulation

However, the mechanisms by which AMF shields Zelkova serrata, an economically vital tree species in southern China, from AR stress remain unclear. We conducted a greenhouse experiment in which Z. serrata plants were inoculated with AMF species Rhizophagus intraradices and Diversispora versiformis, either alone or as a mixed culture, or with a sterilized inoculum. In addition, the benefits from AMF symbionts depended on the identification of AM fungal species and the severity of AR stress. AM fungi protect Z. serrata against AR stress by synchronously activating photosynthetic ability, antioxidant enzymes, and osmolyte accumulation, according to our results. In southern China, a mixture of R. intraradices and D. versiformis could be a more suitable option for culturing Z. serrata.
