Abstract
Dit rapport presenteert de resultaten van de in 1996
uitgevoerde metingen van de chemische samenstelling van neerslag in
Nederland. De metingen zijn uitgevoerd op 4-wekelijkse monsters verkregen
uit het Landelijk Meetnet Regenwatersamenstelling. Op 15 stations werden
monsters verzameld voor analyse op hoofdcomponenten en op anorganische
microcomponenten (zware metalen). In de monsters van de hoofdcomponenten
werden de concentraties van vrij zuur (hydronium/waterstofcarbonaat),
natrium, kalium, calcium, magnesium, fluoride, chloride, nitraat, sulfaat en
fosfaat bepaald. Voorts werden van deze monsters de geleidbaarheid en de pH
bepaald. De monsters voor zware metalen werden geanalyseerd op cadmium,
koper, lood, ijzer en zink. Bovendien werden de monsters van twee stations
geanalyseerd op arseen, chroom, nikkel en vanadium. Daarnaast werden op
twee stations aparte monsters verzameld voor analyse op het
bestrijdingsmiddel lindaan (g-HCH) en kwik en op een station werden monsters
verzameld voor analyse op een aanvullende set bestrijdingsmiddelen. Deze
set bestaat uit 2,4-D, 2,4,5-T, atrazin, bentazon, cyanazin,
desethylatrazin, desisopropylatrazin, dichloorprop, MCPA, mecoprop,
metolachloor en simazin.
This report presents the results of the chemical composition measurements of precipitation in the Netherlands in 1996. Measurements were performed on 4-weekly samples obtained from the National Precipitation Chemistry Monitoring Network. Samples from 15 stations were analysed for main components and inorganic micro-components (heavy metals). Analysis of the main component samples determined the concentrations of free acid (hydrogen ions/hydrogen carbonate), sodium, potassium, calcium, magnesium, fluoride, chloride, nitrate, sulphate and phosphate, along with conductivity and pH value. The samples for heavy metals were analysed for cadmium, copper, iron, lead and zinc. Arsenic, chrome, nickel and vanadium were also determined in samples from two stations. Additionally, separate samples were taken at two stations for analysis of the component mercury and the pesticide lindane (g-HCH) and at one station for analysis of a supplementary set of pesticides. This set consists of 2,4-D, 2,4,5-T, atrazine, bentazone, cyanazine, desethylatrazine, desisopropylatrazine, dichlorprop, MCPA, mecoprop, metolachlor and simazine.
