Phytoremediation for Arsenic-Contaminated Gold Mine Waste
Arsenic (As)-contaminated gold mine waste is a global problem and poses a significant risk to the ecosystem and community (e.g., carcinogenic, toxicity). Research is investigating environmentally sustainable techniques to remediate As-rich mine waste. Biological techniques involving plants (phytoremediation) and soil amendments have been studied to bioaccumulate As from soil (phytoextraction) or stabilise As in the rhizosphere (phytostabilisation).

Phytoremediation
Phytoremediation is defined as the use of plant species as a means of purifying polluted soil, water, and air. The term derives from the Greek word phyto (“plant”) and the Latin word remedium (“to correct or remove an evil”). Phytoremediation is a more economically feasible and efficient remediation option than other techniques, such as washing, flushing, or solidification.

Phytoplankton as Indicators of Climate Change
Phytoplankton represent a taxonomically diverse group of photosynthetic, mostly single-celled aquatic organisms that drift with the current. Phytoplankton also play an important role in influencing the Earth’s climate and the functioning of the biological carbon pump. The biological carbon pump is a major component of the global carbon cycle and refers to the process by which atmospheric CO2 is transferred by primary producers (mostly phytoplankton) from the eutrophic zone of the ocean to the underlying sediments.

Phytoplankton
Phytoplankton (/ˌfaɪtoʊˈplæŋktən/) are the autotrophic (self-feeding) components of the plankton community and a key part of oceans, seas and freshwater basin ecosystems. The name comes from the Greek words φυτόν (phyton), meaning "plant", and πλαγκτός (planktos), meaning "wanderer" or "drifter". Most phytoplankton are too small to be individually seen with the unaided eye. However, when present in high enough numbers, some varieties may be noticeable as colored patches on the water surface due to the presence of chlorophyll within their cells and accessory pigments (such as phycobiliproteins or xanthophylls) in some species. About 1% of the global biomass is due to phytoplankton.

Phyto-Beneficial Traits of Rhizosphere Bacteria
Beneficial interactions between plants and some bacterial species have been long recognized, as they proved to exert various growth-promoting and health-protective activities on economically relevant crops. As well, rhizosphere bacteria direct activity against some phytopathogenic fungal species (such as Aspergillus and Fusarium spp.) have been also observed, resulting highly interesting since these pathogens cause major yield losses in cereal crops and are well-known mycotoxin producers.

Physical, Chemical, and Environmental Properties of Phthalates
Phthalic acid esters (PAEs), commonly named phthalates, are a class of dialkyl or alkyl/aryl esters of phthalic acid (1,2-benzenedicarboxylic acid) structured in one benzene ring linked with two aliphatic ester groups, most commonly in the ortho configuration.

Physical-Chemical Properties of Nano-Sized Phyllosilicates: Recent Environmental and Industrial Advancements
Phyllosilicates are common minerals that include the most widely known micas and clay minerals. These minerals are found in several natural environments and have unique physical-chemical features, such as cation exchange capacity (CEC) and surface charge properties. When phyllosilicates are nano-sized, their physical-chemical properties are enhanced from those of the micro-sized counterpart. Because of their unique crystal chemical and physical-chemical features, kinetics, and particle size, nano-sized clay minerals (i.e., kaolinite, montmorillonite/illite) and micas (i.e., muscovite) are of great interest in several fields spanning from environmental applications to engineered materials. This paper aims to overview the recent developments of environmental protection and technological applications employing nano-sized natural micas and clay minerals. Emphasis is given to the role that the unique physical-chemical properties of montmorillonite, vermiculite, kaolinite, and muscovite play in nanoparticle formulations, manufacture, and technical performance.

Physical and Chemical Aspects of Fog Water
Fog water have been rapidly increasing due to its negative impacts on different environmental processes. However, fog water harvesting has become beneficial in various countries to overcome water scarcity. Accurate fog forecasting remains a challenging issue due to its spatio-temporal variability and uncertainties despite the development and efforts made to understand its chemistry and microphysics. The literature proved that the decrease in fog frequency over time in most countries is mainly attributed to the improvement in air quality or the change in regional climatic conditions.

Phum Snay
Phum Snay (Khmer: ភូមិ ស្នាយ) is an Iron Age archaeological site discovered in May 2000 in Preah Neat Prey District, Banteay Meanchey Province, Northwest Cambodia, around 80 km (50 mi) from the temple ruins of Angkor. The site was excavated between 2001 and 2003 by primary excavators Dougald O’Reilly of the Australian National University, Pheng Sitha and Thuy Chanthourn. The excavation was intended to discover more about Iron Age life in Cambodia.
