Mining Emissions Effectively Monitored with Micro Pulse LiDAR Technology

Mining operations include blasting, excavating, scraping, and sifting large amounts of dirt. These activities create dust and other emissions that are transported by air currents to surrounding areas. It is easy to say that dangerous particulate matter (PM) generated by mining should be monitored and kept to a minimum; however, it is very challenging to measure the levels of contaminants in the ...

7 Disadvantages of Implementing an Activated Sludge Process For Your Municipality or Company

Biological treatment processes are an important component in many wastewater treatment systems. They are one of the most efficient and effective ways of reducing organic material in wastewater. There are quite a few of them that have been researched and used over several decades. However, one of the most widely used conventional biological treatment process is the activated sludge process (ASP). ...

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 ...

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, ...

Top 5 Differences between Micro Pulse LiDAR and Ceilometer Technology

If you are evaluating backscatter LiDAR sensors for measuring aerosols, cloud vertical structure, and planetary boundary layer (PBL) heights, what factors should you consider in your comparison? It really comes down to a choice between the traditional analog technology used in ceilometers and the more recent advanced technology found in Micro Pulse LiDAR (MPL) sensors. ...

Multiple Instruments Work Together for a Better View of Air Quality

Accurately identifying and quantifying particulate matter (PM) in the atmosphere is key to determining air quality. Researchers are particularly interested in PM that have a diameter of less than 2.5 micrometers because they are believed to contribute to heart and lung disease in humans and animals. These tiny particles are invisible to the naked eye and originate from power plants, fires, and ...

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 ...

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 ...

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 ...

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 ...

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 ...

Trends of lead in suspended particulate matter in Zagreb air

Monitoring of lead in Total Suspended Particulate Matter (TSPM) started in Zagreb, Croatia in 1971 at three measuring sites. Monitoring of lead concentrations in PM10 started in 1999. This paper presents the trends of annual mean values for lead concentrations in TSPM and in PM10 particles. The obtained data showed a decreasing trend of lead in TSPM, especially during the last ten years when the ...

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 ...
