The pollution indices of microplastic content in bottled water from South Eastern Nigeria were evaluated. Microplastic contamination factors, load and risk index, polymer and...

There are many potential risks to human health from heavy metal contamination of vegetables resulting from wastewater irrigated sites. This study was carried out to assess the concentration of chromium (Cr) and the risk to human health by chromium through the intake of locally grown vegetables collected from wastewater irrigated agricultural fields. Twenty-seven samples of 9 (nine) different ty...

This paper presents a novel method for determination of insulator contamination (IC) level. ICs caused some problems in electric networks. Some faults occur in electric system due to ICs. These faults sometimes log to a sudden and serious damages to the systems. So ICs reduce power quality and reliability indexes. Usually insulator washing is a solution for this problem and its events. Insulato...

objective: metal concentrations in 53 soil samples of shahr-e-babak were determined.  methods: assessment of enrichment factor and geo-accumulation index revealed higher degree of contamination of cd, pb, and cu in soil samples. moreover, results of metal fractionation study revealed high amount of cd and pb are associated in weakly bounds may lead to environmental risk of these metals.  result...

UNLABELLED   Previously, the author proposed a 'fungal index' that quantifies the capacity for fungal growth in a test environment where a device (fungal detector) encapsulating spores of a xerophilic sensor fungus Eurotium herbariorum was placed. It was also found that an extremely xerophilic fungus, Aspergillus penicillioides, was suitable as a sensor fungus at sites with lower relative humid...

Solanum nigrum L. has a delightful prospect as hyperaccumulation plant for cadmium pollution remediation, and microplastic is new type of that received wide attention. In this study, the effects polyethylene microplastics (LDPE) (0.135, 0.27, 0.81 1.35 mg·kg-1) (20 on growth indexes soil physical chemical properties were investigated in 17-day microcosm experiment. The results showed single LDP...

We assessed the spatial and temporal variations of pollution indicators and geochemical and trace metal parameters (23 in total) from water and sediment (144 samples) of three different eco-niches (beach, fishing harbor, and estuary) in larger coastal cities of southern India (Cuddalore and Pondicherry) for one year. A total of 120 marine Pseudomonas isolates were challenged against different c...

This article is the second of a three-part series that investigates the application of the ventilation equations to designing and testing cleanrooms. This part is concerned with the decay equation. The recovery test, described in ISO 14644-3 (2005) is discussed, and improvements recommended. The application of the decay equation to the ‘clean up’ requirement given in the EU GGMP (2008) is also ...
