Abstract
Het Landelijk Meetnet Bodemkwaliteit (LMB) heeft als
primaire doelstelling de trendmatige veranderingen na te gaan in de
kwaliteit van de bodem ten gevolge van diffuse belasting van de bodem. Het
object van onderzoek is de toplaag van de bodem (0-10 cm); daarnaast wordt
ook een diepere bodemlaag en het bovenste grondwater onderzocht. Het LMB
wordt in samenwerking met LEI-DLO en AB-DLO uitgevoerd. Jaarlijks worden
een 2-tal combinaties van bodemgebruik en grondsoort bemonsterd, bestaande
uit ca. 20 locaties per combinatie. In 1993 is gestart met de bemonstering
van landbouwgrond op zandgrond. Voor het bodemgebruik landbouw is het
bedrijf de schaal van de locatie. De categorieen die in 1994 zijn
onderzocht, zijn melkveehouderijbedrijven met een groot aandeel intensieve
veehouderij op zandgrond en bos op zandgrond. Naast algemene
kwaliteitsparameters zijn parameters onderzocht die gerelateerd zijn aan de
milieuthema's vermesting en verspreiding. Vermestingsparameters zijn
fosfaat (bodem en grondwater) , nitraat, kalium en ammonium (grondwater).
Voor verspreiding zijn zware metalen onderzocht (bodem en grondwater).
Voorts zijn bodemgehalten aan PAK en een aantal
organochloorbestrijdingsmiddelen (OCB) bepaald.
This report contains the results of the National Soil Monitoring Network of the Netherlands in 1994, the second year of sampling. The network represents a cooperative effort of the National Institute of Public Health and the Environment (RIVM), the Agriculture Economics Research Institute (LEI-DLO) and the Research Institute for Agrobiology and Soil Fertility (AB-DLO). The primary objective of the network is to identify changes in soil quality over time. The network's secondary objective is to identify the actual quality of soil and upper groundwater. Attention is focused primarily on rural areas. The monitoring program involves sampling 40 locations yearly over a period of five years. In 1993 the network started by sampling the soil and upper groundwater on 35 dairy-cattle farms in the sandy regions of the Netherlands. In 1994, 20 intensively managed cattle farms (i.e. farms with a high phosphate production) and 20 forest sites (deciduous, pine and mixed vegetation) on sandy soils were sampled. Concentrations of heavy metals, polycyclic aromatic hydrocarbons (PAHs), organochlorine pesticides and triazines in the topsoil (0-10 cm) and the litter layer of the forest sites have been reported. Concentrations of macroparameters, nutrients and heavy metals in the upper groundwater are also presented. The measured concentrations are compared with the Dutch objectives for soil and groundwater quality (target values).
