development of a green belt with suitable plant species around the source of emission can mitigate the atmospheric contamination. selection of such plant species are required to combat air pollution based on their tolerance level. present study was undertaken to evaluate the tolerance level of higher plants in east of esfahan city, iran, during 2011 in terms of assessing air pollution tolerance...

Background: Considering the toxic effects of heavy metals and microbial pathogens in industrial wastewaters, it is necessary to treat metal and microbial contaminated wastewater prior to disposal in the environment. The purpose of this study is to assess the removal of heavy metals pollution and microbial contamination from a mixture of municipal and industrial wastewater using membrane biorea...

This paper presents the results of theoretical analyses conducted to investigate potential of various particle removal techniques. The purpose is to limit the extent of cross contamination caused by the small particles generated through in situ handling and processing of the simulated Martian rock. Since the same hardware would be used to process several rocks, the cross contamination is define...

Baihua Reservoir in Guizhou Province, China, experienced serious Hg contamination from Guizhou Organic Chemical Plant (GOCP) between 1971 and 1997. However, the biogeochemical cycling of Hg in this reservoir is not well studied. Sediment cores were collected in fall 2002, spring 2003 and in spring and fall 2004. THg and MeHg concentrations in all sediment profiles ranged from 0.26 to 38.9 mg/kg...

Abstract In the field of failure analysis and in particular molecular particulate contamination, being able to detect any trace contaminants during integration an orbital spacecraft is crucial. this context, fluorescence allows not only but also discriminate contaminants. We studied response two epoxy adhesives, typical sources contamination orbit with a portable broadband hyperspectral instrum...

Scatterometer Contamination Mitigation

Development of a green belt with suitable plant species around the source of emission can mitigate the atmospheric contamination. Selection of such plant species are required to combat air pollution based on their tolerance level. Present study was undertaken to evaluate the tolerance level of higher plants in East of Esfahan city, Iran, during 2011 in terms of assessing Air Pollution Tolerance...

OBJECTIVE To study the association between environmental factors, prevalence of asthma and respiratory morbidity in relation to air quality levels in a mega city. To study modifiable environmental factors in people with diagnosed asthma and increased respiratory morbidity. METHODS Cross sectional survey of population (N-3233) from 6 localities near air quality stations was done to study preva...

Heavy metals and dyes are major contributors in contamination of water streams. These contaminants enter into our eco- system, thus posing a significant threat to public health, ecological equilibrium and environment. Thus a combined discharge of these contaminants results in water pollution with high chemical oxygen demand, biological oxygen demand, color, particulate matter, suspended particl...

The healthcare industry is challenged with meeting stringent quality requirements regarding the manufacturing of drug products. Packaging components are critical to this operation. Because of these requirements, each final container processed for parenteral preparation must be inspected thoroughly for the presence of visible particulates. According to USP 32-NF 27, “Each final container of all ...
