Sustainable management practices can be applied to the remediation of contaminated land to maximise the economic, environmental and social benefits of the process. The Sustainable Remediation Forum UK (SuRF-UK) have developed a framework to support the implementation of sustainable practices within contaminated land management and decision making. This study applies the framework, including qua...

Phytoplanktons are the first bio- indicators of pollution in aquatic ecosystems. Phytoplankton assemblage and aquatic ecosystems are always influenced by environmental factors therefore these environmental changes and threats must be understood in any ecosystem. Phytoplankton are inexpensive and readily available bio- indicators. In the present study, phytoplankton were used to study the Sefid ...

Typically, population-based sequencing of HIV does not detect minority variants present at levels below 20-30%. Single genome amplification (SGA) and sequencing improves detection, but it requires many PCRs to find the optimal terminal dilution to use. A novel method for guiding the selection of a terminal dilution was developed and compared to standard methods. A quantitative real-time PCR (qR...

Environmental changes and heavy metal pollution are some of the consequences anthropogenic activities. Many ecosystems, including edaphic suffer from effects pollution. The accurate assessment soil contamination leads to better approaches for remediating soils. exploration different ways, biological methods, conduct environmental monitoring is still ongoing. Here, we focus on reviewing potentia...
