The paper presents atmospheric stability description by the use Richardson number (Ri). The calculation was done for two types o f weather: sunny days (24h) and cloudy days (24h). In accordance with Oke (1987) stability static was divided as follows: unstable stability a-fully forced convection, b-mixed convection, c-free convection; d-neutral stability; stable stability e-fully forced convection,...
Modern methods allows accurately analysis of quality and quantity of particulate matter suspended in the air. Measurement particulate matter PM10 was done in Ursynów-WAU since January 2002 by the use of dust sampler. Ana ysis of the results shows permissible level D24 was excced 8 times in the period since January to December 2002. Th e most high concentrations was recorded during inflow northen and...
Measurement carbon monoxide (CO) conceniration was done in Ursynów-WAU since February 2001. The primary sources of CO in Ursynów are motor vehicles and local emission. The annual and 24h mean concentrations CO in 2001, 2002 accounted for 40-56% of air quality standards. The 8-hour carbon monoxide concentration exceeds lower threshold evaluation in November 2002.
The paper presents meteorological data in the station Ursynów -WAU 1998 and characteristics of oxygen content (O2) in the air: means, maximum, minimum, range, standard deviation (Tab. 1, 2). Partial correlation coefficients of oxygen content in the air and temperature, vapour pressure, air pressure are: -0,998; -0,834; 0,999 for January and -0,999; -0,993; 0,997 for July.
Tlen jest pierwiastkiem odgrywającym szczególną rolę w środowisku. Bierze udział w procesach życiowych i reakcjach chemicznych organizmów, dlatego zmiany jego zawartości w powietrzu mogą stanowić zagrożenie dla ich odpowiedniego przebiegu. Głównym celem pracy było określenie zmian zawartości tlenu w powietrzu atmosferycznym (w przebiegu dobowym miesięcznym i rocznym) aglomeracji warszawskiej. Do analizy...
