Exposure and risk estimation for pesticides in high-volume spraying

During twenty applications with a spray pistol of methomyl to chrysanthemums, inhalation exposure as well as potential and actual dermal exposure were monitored using the 'whole-body'-method. On the basis of the exposure data, in terms of exposure to the liquid formulation and the spray liquid, the possible health risk for methomyl and thirteen...

Exposure to methyl bromide during greenhouse fumigation on Crete, Greece

In agricultural areas where greenhouses and dwellings are intermixed, the general population as well as the professional applicators may be exposed to pesticides. In a field study on Crete, exposure to methyl bromide during soil fumigation was assessed. Exposure of applicators (both contractors and farmers) were measured with personal air...

Oriënterend onderzoek naar blootstelling aan stof bij ondervloerders

In de bouw brengen ondervloerders op het beton een afwerklaag van zandcement aan om elektriciteits- en verwarmingsbuizen te bedekken en een egale ondergrond te verkrijgen. Ondervloerders worden blootgesteld aan een aantal werkomstandigheden, zoals fysiek zware belasting, een slecht klimaat, huidaandoeningen en stof. In dit onderzoek is de...

Exposure to pesticides during and after application in the cultivation of chrysanthemums in greenhouses: Health risk and risk management

Exposure to pesticides: Pt. III Application to chrysanthemums in greenhouses

During 20 applications with a spray pistol of methomyl to chrysanthemums, inhalation exposure as well as potential and actual dermal exposure were monitored. Inhalation exposure during mixing, loading and application averaged 5.1 microgram/hour. Dermal exposure of the hands during mixing and loading, and application was 13.1 mg/hour, and 0.8 mg...

Dissipation of aerosols from greenhouse air after application of pesticides using a low-volume technique implications for safe re-entry

The application of pesticides using Low-Volume (LV) techniques (volume rate < 50 l/ha) is of growing interest for crop protection in greenhouses. An important LV-technique is the Low Volume Mister (LVM), generating fine droplets (volume mean (aerodynamic) diameter varying from 14 up to 32 μm). Field experiments in a commercial greenhouse have...

Inhalation exposure to 1,3-dichloropropene in the Dutch flower-bulb culture. Part I. Environmental monitoring

Respiratory occupational exposure to the Z- and E-isomers of 1,3-dichloropropene (DCP) of twelve commercial applicators was assessed. The time-weighted average (TWA) concentrations of DCP ranged from 1.9 to 18.9 mg/m3. On 30% of the observed working days the Dutch occupational exposure limit of 5 mg/m3 was exceeded. Short-term exposure levels...

Het verdwijnen van bestrijdingsmiddelen uit kaslucht na toepassing met een laag-volume techniek

Dit rapport doet verslag van een onderzoek naar het mogelijke gezondheidsrisico bij het herbetreden van kassen na toepassing van bestrijdingsmiddelen met een neveltechniek, de zogenaamde Low Volume Mister (LVM)-techniek. Voor twee bestrijdingsmiddelen, het vluchtige dichloorvos en het niet-vluchtige thiofanaat-methyl, werd het verloop van de...
