Matter Concentration

Total suspended particulate matter concentration and grain size spectra, total and living particulate carbon, and dissolved nitrogen and carbon were measured at stations along the length of Petpeswick Inlet and over several tidal cycles. Distinct particle populations were associated with the water at the head and at the mouth of the inlet. Mixing of water masses and temporal periodicities cause variance in particle concentration and spectral shape which correspond to seasonal, tidal, and seiche variations. To explain the last, a process of transformation of organic matter between dissolved and particulate states by aggregate formation and breakup in response to turbulent changes is proposed.Key words: Petpeswick Inlet, Nova Scotia, particulates

Positive Effect

The subject of the paper is the influence of atmospheric circulation on the content of suspended PM10 in the air in Konin. For this purpose dust concentrations from the period 2012–2016 were generally characterized. PM10 particulate matter concentration average hourly data were obtained from the Main Inspectorate of Environmental Protection website. Based on these data, long-term, seasonal and daily changes in the PM10 concentration in the atmosphere were investigated. The study analysed the daily variability of the PM10 suspended particulate matter concentration to present seasonal differences (in hot and cold seasons). In order to determine the influence of atmospheric circulation on the PM10 particulate matter concentration, the concentration levels data were compared with the types of circulation prevailing on the same day. In this study according to synoptic maps the days with maximum and minimum concentrations PM levels were analysed. It was found which type of meteorological circulation is conducive to higher levels concentrations of particulate matter PM10, and which has a positive effect on the quality of the air in Konin.
