Study of particulates and metallic elements at a farm sampling site in central Taiwan

The total suspended particle (TSP) concentration, dry deposition and wind speed were measured with a PS-1 sampler, a dry deposition plate and a Weather Monitor II (#7440), respectively, at the Experimental Farm of Thunghai University in Taiwan. Taiching Industrial Park, Taichung Cong Road (traffic) and a hospital incinerator are close to the sampling site. The sampling time was from August 2001 ...

Characteristic study of particulates and metallic elements at an urban sampling site in Taichung, central Taiwan

Atmospheric total suspended particulate concentrations and metallic element concentrations were measured at three locations, characteristic of urban, suburban and rural sites. The sampling period was from July 2000 to August 2000. The results indicated that the urban sampling site had the highest total suspended particulate concentrations (average 108.61µ1m³), followed by the suburban site ...

A study of atmospheric particulate matter in a city of the central region of Brazil using time-series analysis

Uberlandia is an important city of the Brazil central region. In this work, the Total Suspended Particles (TSP) and particles smaller than 10 μm (PM10) were sampled from 2003 to 2006. The Geostatistical technique was used to evaluate the temporal dependence and the time-series analysis with 2004 and 2005 data was used to predict 2006 values. The selection of the best model was conducted using ...

Distribution of pyrethroid insecticides in secondary wastewater effluent

Although the freely dissolved form of hydrophobic organic chemicals may best predict aquatic toxicity, differentiating between dissolved and particle bound forms is challenging at environmentally relevant concentrations for compounds with low toxicity thresholds such as pyrethroid insecticides. We investigated the distribution of pyrethroids among three forms: freely dissolved, complexed with ...

Pollution, natural resource and economic growth: an econometric analysis

Theoretical arguments imply that an inverted U-shaped relationship may be quite plausible. It is still not clear from the empirical literature whether the relationship of income and environmental degradation is linear or inverted U-shaped. This paper utilises a more global representative sample, than previous EKC studies, and re-evaluates the environmental Kuznets curve (EKC) of sulphur dioxide, ...

Variations of carbon transport in the Yellow River, China

The Yellow River is the second largest river in China. Carbon transport by the Yellow River has significant influence on riverine carbon cycles in Asia. In order to monitor seasonal and spatial variations of carbon concentrations and to estimate carbon exports, water and suspended solids were sampled every 10 days at three representative stations (Qingtongxia, Tongguan, and Luokou) along the ...

Differentiation of Mass and Flow Limited Rainfall-Runoff Events for Overland Flow from Small Urban Catchments

ABSTRACTWater quantity and quality are coupled phenomena in urban rainfall-runoff. These rainfall-runoff quantity and quality relationships have been significantly altered by the built environment and associated anthropogenic activities. Understanding the relationship between quantity and quality of urban overland flow for a given catchment facilitates development of in-situ wet weather control. ...

Feasibility Study of an Express Assessment Protocol for the Indoor Air Quality of Air-conditioned Offices

It is costly to sample all major toxic pollutants in community air. Sampling should be conducted based on an assessment strategy and monitoring planning. Assessment methods that rely on monitoring some representative pollutants have been proposed variously at different times. In Hong Kong, the Environmental Protection Department (HKEPD) launched an Indoor Air Quality (IAQ) certification scheme to ...

Chlorine Disinfection of Blended Wastewater Effluents

KeywordsBlended Wastewater, Disinfection IntroductionFlow to publicly owned treatment works (POTWs) increases during wet weather events, due to intrusion of storm water into sanitary collection systems and use of combined sewer systems. When such flows exceed the hydraulic capacity of a POTW alternate flow management techniques must be employed to ensure that ...

Sedimentation of chlorophylls in an Arctic fjord under freshwater discharge

Sedimentation of chlorophylls was studied during summer 1997 in Adventfjorden (Spitsbergen, Arctic). During the period of study, the water column was found to be well stratified by a freshened surface layer (salinity ...

Bioavailability and fate of Phosphorus in constructed wetlands receiving agricultural runoff in the San Joaquin Valley, California

Elevated nutrient concentrations in agricultural runoff contribute to seasonal eutrophication and hypoxia in the lower portion of the San Joaquin River, California. Interception and filtration of agricultural runoff by constructed wetlands may improve water quality of return flows ultimately destined for major water bodies. This study evaluated the efficacy of two small flow-through wetlands (2.3 ...

Ambient air quality levels in Tehran, Iran, from 1988 to 1993

The objectives of this study were to describe trends in ambient air quality in Tehran between 1988 and 1993, to determine if these levels exceeded the World Health Organization (WHO) guidelines, and to discuss possible health effects related to exposure for these particular pollutants. Data were acquired from Iran's Environmental Protection Agency (IEPA) and the Ministry of Health (MH). These ...

Dust monitoring

Generally, two different approaches are used to measure the amount of dust deposited on a surface; Determination of the soiling of a surface, by a change in its properties; Determination of the quantity of dust deposited, by weight. WHAT IS DUST? Dust is a generic term used to describe fine particles that are suspended in the atmosphere. Dust comes from a wide variety of sources, including soil, ...

Data Requirements for Soil, Sediment, and Sludge

Site soil conditions frequently limit the selection of a treatment process. Process-limiting characteristics such as pH or moisture content may sometimes be adjusted. In other cases, a treatment technology may be eliminated based upon the soil classification (e.g., particle-size distribution) or other soil characteristics. Soils are inherently variable in their physical and chemical ...
