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 ...

Measurement of TOC in High-Salt Sample

The quantity of organic matter in seawater is important in the research and monitoring of marine pollution as an indicator of organic pollution. The salt content in seawater is typically about 3.5 %, but using the Shimadzu total organic carbon analyzer, it is possible to measure the TOC directly without dilution or other pretreatment procedures. Here, we introduce an example of measurement of ...

Regulatory dispersion modelling in Finland

We present a review of regulatory atmospheric dispersion models and their application to environmental impact assessment (EIA) in Finland. The following regulatory models are available: the urban dispersion modeling system, models for dispersion of vehicular pollution, the air pollution information system, and the dispersion model for odorous compounds. All of these models are connected to a ...

How to turn human waste into disease-free fertiliser

Poor sanitation can contaminate drinking water, especially in rural areas. Unless properly dealt with, faeces and other human waste can pollute the soil and eventually wells, causing diseases such as diarrhoea. The EcoSanitation method provides a safe way to dispose of human waste. Today, a research project in Tanzania examines the potential of combining this system with a composting technique ...

Clearing the Air: Reducing Diesel Pollution in West Oakland

Diesel exhaust — the black smoke coming out of buses, trucks, trains, and ships — is the number one toxic air pollutant in California.1 Chemicals in diesel pollution can cause cancer, harm the reproductive system and aggravate or cause asthma. New research shows that West Oakland, California, a neighborhood surrounded by freeways and bordered by the Port of Oakland, suffers from far more than its ...

Research on applying a water-lifting aerator to inhibit the growth of algae in a source-water reservoir

A new hydraulic, water-lifting aerator was developed for ameliorating water quality. It aims at mixing lower and upper water bodies, controlling algae growth, increasing dissolved oxygen concentration in water and inhibiting the release of pollutants from sediments. This new device was applied to control the algae growth in surface water of the water source of Tianjin. It was found that the ...
