Isotachophoresis using coupled capillaries (ITP) and ion chromatography (IC) – two analytical procedures for the determination of anions in atmospheric wet deposition – were compared. Both techniques were used for the determination of anions in small volume samples of dew, rime and fog deposition. IC was characterized by lower limits of detection and quantitation. The wide dynamic range of the technique...
Organometallic compounds are widely used in almost all sectors of industry. As a result of emissions from natural and anthropogenic sources they are released to the environment, where they undergo a variety of conversions and interactions. Some organometallic compounds exhibit high toxicity. Organometallic compounds of mercury, tin, lead, selenium and arsenic are among the most common and hazardous...
Our paper discusses many types of samplers used for collecting samples from precipitation and atmospheric deposits (fog and cloud water, dew, hoarfrost and rime). Equipment of various degrees of automation is presented. The paper also presents bibliographical information on the concentration range of inorganic and organic compounds in precipitation and atmospheric deposit samples, the storage and/or...
All chemical compounds may undergo a variety of processes resulting from chemical, biological or photochemical reactions. Depending on the environmental compartment in which organic compounds are present (e.g. soil, benthic sediments, surface and ground waters), they can undergo slow changes resulting from different chemical, physical, biological or photochemical processes. The problem of intermediate...
Transport and accumulation of large amounts of natural and man-made substances takes place in the Odra River. The river is a significant source of pollution for the Baltic Sea. The presence of toluene in the samples of benthic sediments collected after the flood in 1997 was an unexpected find made within the framework of the International Odra Project (IOP). At that time, the origin of toluene, which...
An analysis of concentrations of phenols in runoff in the area of Gdańsk was performed during one month of heavy rain. Five sampling places localised along streets of heavy traffic were selected. Phenol and 3,4-dimethylophenol were most often found in samples, while concentrations of phenol (120.3 – 911.6 ng/l), chlorophenol (613 ng/l) and p-nitrophenol (469.4 ng/l) were the highest.
The paper presents the results of determination of concentrations of chloride, sulfate, phosphate, ammonium, sodium, potassium, calcium and magnesium ions along with total nitrogen, pH and electrolytic conductivity for precipitation collected in nonindustrialized regions near Gdansk (Poland). A station used for the collection of samples of precipitation consisted of two substations, on of which was...
