TL;DR: Soil microorganisms are the first living organisms subjected to the impacts of metal contamination, and changes in microbial biomass, activity, and community structure as a result of increased metal concentration in soil may be used as indicators of soil contamination or soil environmental quality.

TL;DR: The results indicate that S. alfredii has an extraordinary ability to tolerate andhyperaccumulate Cd and this is the first report of the new Cd hyperaccumulator S.–alfred ii Hance, which provides an important plant material for understanding the mechanisms of Cd/Zn co- Hyperaccumulation and for phytoremediation of the heavy metal contaminated soils.

TL;DR: Once the rate-limiting steps for uptake, translocation, and detoxification of metals in hyperaccumulating plants are identified, more informed construction of transgenic plants would result in improved applicability of the phytoremediation technology.

TL;DR: It is expected that recent advances in biotechnology will play a promising role in the development of newhyperaccumulators by transferring metal hyperaccumulating genes from low biomass wild species to the higher biomass producing cultivated species in the times to come.

TL;DR: In this paper, the authors provide information on recent research progresses and regulation efforts regarding land application of biosolids, including forms and types and nutrient values of bio-solids, environmental and health concerns, and related best management practices (BMPs), with emphasis on its land application in agriculture.
