Physico-chemical analysis of the sediment samples collected from Thane Creek of Maharashtra, India

Thane Creek is one of the most important ecosystems around Mumbai and Thane, and the mangroves surrounding the ecosystem form the vital green lung for the residents. It is also an important feeding and breeding ground for fishes. Locals have been living in harmony amidst this ecosystem for ages, but in recent past, man has misused this ecosystem by way of releasing sewage, dumping solid waste, ...

Bulked segregant analysis using the goldengate assay to locate the Rpp3 Locus that confers resistance to soybean rust in soybean

Few resistance loci to soybean rust (SBR), caused by Phakopsora pachyrhizi Syd., have been genetically mapped and linked to molecular markers that can be used for marker assisted selection. New technologies are available for single nucleotide polymorphism (SNP) genotyping that can be used to rapidly map traits controlled by single loci such as resistance to SBR. Our objective was to demonstrate ...

A geochemical and statistical approach for assessing heavy metal pollution in sediments from the southern Caspian coast

Abstract: The nearshore marine environment of the Caspian sea is a major repository for toxic metals originating from various sources. Since the persistent toxic metals pose serious health risks this research concentrated on investigating the concentrations and spatial distribution of metals in the nearshore sediments along the Iranian coast of the Caspian sea. Fourteen sampling sites were ...

A statistical examination of the integration of biotechnology in the Indian pharmaceutical sector

From the beginning of the 1970s a number of Indian pharmaceutical firms had invested in gaining technological competence without having "formal R&D centres"; and through efficient "reverse engineering" had slashed the prices of products otherwise sold by Western multinationals. However, their knowledge base was founded on the chemical technology of creating bulk drugs and ...

Elucidation of Exopolysaccharide Isolated from a Dow Wastewater Treatment Facility

ABSTRACT A UNOX wastewater treatment facility in a Dow Chemical site has experienced major operational challenges as a result of a microorganism producing copious amounts of slime in the activated sludge flocs believed to be involved in viscous bulking. Viscous bulking within the clarifying basin causes the rake arms to freeze due to high sheer stress, resulting from poor compaction and ...

Feasibility of Soil Dust Source Apportionment by the Pyrolysis-Gas Chromatography/Mass Spectrometry Method

This study tested the feasibility of using pyrolysis (Py)-gas chromatography (GC)/mass spectrometry (MS) to obtain organic chemical species data suitable for source apportionment modeling of soil-derived coarse particulate matter (PM10) dust on ambient filters. A laboratory resuspension apparatus was used with known soils to generate simulated receptor filter samples loaded with 0.4 mg of PM10 ...

Comparing Gravimetric and Centrifugal Spin Data: Accuracy of Suspended Solids Results and Process Control Calculations

ABSTRACT: The Carbondale Wastewater Treatment Facility is located on the banks of the Roaring Fork River at the intersection of Highway 82 and Highway 133 on Colorado’s western slope. Samples for total suspended solids (TSS) were analyzed by gravimetric analysis with 45 mm filter papers and by centrifugal spin for three years. While there is a clear correlationbetween centrifuge and ...

Time is of the essence in plastics

Introduction Determining the moisture content in plastics is an important step in the extrusion and molding process of many industrial resins. Excessive moisture content can lead to microscopic steam pockets that can blister or weaken the integrity of the molded product. Plastic pellets in a saturated or ‘wet’ state can also mislead buyers of bulk plastic since ...

Asbestos in Dusts Can Pose Health and Safety Issues for Building Occupants

Asbestos was used heavily in many building materials in the United States up until the mid-1980s. According to the U.S. Environmental Protection Agency (EPA), “Asbestos fibers may be released into the air by the disturbance of asbestos-containing material during product use, demolition work, building or home maintenance, repair, and remodeling.” The EPA goes on to report, ...

The use of aquatic plant Elodea canadensis to assess toxicity and genotoxicity of sediments of the Yenisei River

We estimated toxicity, cyto‐ and genotoxicity of bulk sediments from the Yenisei River in laboratory bioassay based on using several endpoints of aquatic plant Elodea canadensis (Elodea). The samples of bottom sediments (BS) were collected in the Yenisei River upstream and downstream of the sources of chemical and radioactive contamination. The testing revealed different sensitivities of ...

Composition and Contaminant Loads of Residual Household Waste Part III: Physico-Chemical Properties and Contaminant Concentrations

Abstract. Physico-chemical properties of residual waste are key factors for disposal standards. Reliable input data for treatment plants (MSWI) need to consider the heterogeneity and variability of waste composition. This requires thoroughly designed sampling schemes, a consistent separation of bulk waste into uniform fractions, and adequate methods for sample preparation and analysis. The ...
