Polycyclic Aromatic Hydrocarbons (PAHs) are fused-ring hydrocarbon compounds that are highly recalcitrant under normal conditions due to their structural complexity and strong molecular bonds. These groups of petrochemicals are mainly found in petroleum-refining plants, accidental oil spills and pipe leakages, and rainwater run-off from roadway. Improperly managed and disposed PAHs can cause en...

risk of microbial contamination in the cosmetic products and transmission to consumers especially in smuggled preparations is very high. according in this study, the microbial content and pollution some of the sunscreen creams in the market and one sample in official market as witness were evaluated. the microbial content (bacterial total count, fungal count, and presence of pseudomon asaerogin...

From the last few years, the inclusion of microbial phytase in poultry diets has increased significantly, mainly in response to heightened concerns over phosphorus pollution of the environment and as cheaper means to make phosphorus available to birds from phytate. Phytate is the major form of phosphorus, abundantly found in cereal grains, beans and oilseed meals used in poultry diet but the mo...

The virtual elimination of the principal point sources of human bacterial pollution through advanced treatment systems has not produced 100% compliance with microbial standards at all UK bathing water locations where they have been installed. This is partly explained by the existence of diffuse bacterial pollution derived from agricultural activities within catchments draining to the bathing zo...

The microbiological quality of coastal or river waters can be affected by faecal pollution from human or animal sources. An efficient MST (Microbial Source Tracking) toolbox consisting of several host-specific markers would therefore be valuable for identifying the origin of the faecal pollution in the environment and thus for effective resource management and remediation. In this multidiscipli...

Groundwater pollution is a serious worldwide concern. Aromatic compounds, chlorinated hydrocarbons, metals and nutrients among others can be widely found in different aquifers all over the world. However, there is a lack of sustainable technologies able to treat these kinds of compounds. Microbial electro-remediation, by the means of microbial electrochemical technologies (MET), can become a pr...

Use of synthetic pesticides causes some unfortunate consequences such as environmental pollution, pests/ vector resistance and toxicity to other non-target organisms including human beings, biological pesticides from plant, microbial origin are environmentally safe pesticides. Microbial insecticides are especially valuable because their non-toxicity to non-target animals and human beings. Labor...

The risk of microbial contamination in the cosmetic products especially in smuggled preparations and transmission of it to consumers is very high. In this study, the microbial content and the pollution of some sunscreen creams in the market and one sample in official market as witness were evaluated. The microbial content (bacterial total count, fungal count, and presence of Pseudomon asaerogin...

The present study is imported to solve two critical problems we face in our daily life which are microbial pollution and colon cancer. One pot green synthesis of a water soluble polyelectrolyte complex (PEC) between cationic polysaccharide as N,N,N-trimethyl chitosan chloride (TMC) and anionic polymer as poly (acrylic acid) (PAA) in presence of silver nanoparticles to yield (TMC/PAA/Ag) nanocom...

17 Nitrogen pollution affects many peatlands with consequences for their biodiversity and ecosystem 18 function. Microorganisms control nutrient cycling and constitute most of the biodiversity of peatlands 19 but their response to nitrogen is poorly characterised and likely to depend on the form of deposition. 20 Using a unique field experiment we show that ammonia exposure at realistic point s...
