All trademarks are the property of their respective owners. TI Designs This TI Design provides an analog front-end (AFE) solution for measuring PM2.5 and PM10 particulate matter (PM). The design detects the light scattered by particles suspended in air. A sample software algorithm is provided to convert the analog output of the design into a particle size and concentration measurement. Test res...

The impact on coastal ecosystems of suspended solids, organic matter, and bacteria in shrimp farm effluents is presented. Sites around Bahía de Kino were selected for comparative evaluation. Effluent entering Bahia Kino (1) enters Laguna La Cruz (2). A control site (3) was outside the influence of effluents. Water quality samples were collected every two weeks during the shrimp culture period. ...

Rare earth element (REE) concentrations and neodymium isotopic composition (ɛNd) are tracers for ocean circulation and biogeochemistry. Although models suggest that REE release from lithogenic sediment in river discharge may dominate all other REE inputs to the oceans, the occurrence, mechanisms and magnitude of such a source are still debated. Here we present the first simultaneous observation...

Flue gas conditioning (FGC) systems offer an effective option for control of Particulate Matter (PM) emissions and enhances the performance of the Electrostatic Precipitators (EPs) when using coal of different properties. The increasing environmental awareness and the mandate of the Environmental Protection Agencies (EPA) in various countries to thermal power stations using coal-fired boilers f...

The relationship between light extinction coefficient (kT) and Secchi depth (ZSD), as well as that between these variables and chlorophyll-a concentration (chl-a) and suspended material (SST) was studied in the Sau reservoir between 1995 and 2001. The results show that kT and ZSD are correlated by the equation kT = 1.36 ZSD, although this relationship exhibits a high inter-annual variability. A...

backgrounds and objectives: the dispersion of particulate matter has been known as the most serious environmental pollution of cement plants. in the present work, dispersion of the particulate matter from stack of kerman cement plant was investigated using computational fluid dynamics (cfd) modeling.materials and methods: in order to study the dispersion of particulate matter from the stack, a ...

Air pollution, especially airborne particulate matter, is becoming a major problem in Chiang Mai. The present study reports findings on total suspended particulate matter (TSP) loading as well as its spatial and daily variation in Chiang Mai ambient air. Limited elemental analysis of airborne particulate matter was also performed. Samples were collected at four different sites, representative o...

Monitoring of surface waters is primarily done to detect the status and trends in water quality and to identify whether observed trends arise from natural or anthropogenic causes. Empirical quality of river water quality data is rarely certain and knowledge of their uncertainties is essential to assess the reliability of water quality models and their predictions. The objective of this paper is...
