Determination of aerosol strong acidity losses due to interactions of collected particles: Results from laboratory and field studies
(Elsevier, 1992-04)
Existing methods of measuring atmospheric aerosol strong acidity adequately prevent neutralization of fine-particle acidity by removing course alkaline particles and gaseous ammonia from air samples. However, these techniques ...
Application of tracer techniques to continuous-flow toxicity testing
(Elsevier, 1987-10)
Frequent toxicant analyses are essential for good quality data in long-term continuous-flow tests. Due to the time consuming and costly chemical analyses, exposure levels are measured at best on a daily basis. These ...
Modelling regional waste water treatment systems
(Elsevier, 1973-04)
The economies of scale of waste water treatment plants favor regional systems. This paper presents a mathematical formulation of this problem, and suggests an algorithm for solution. Several case examples are shown.
