Since January 1 , 2018 , there has been a refinement certificate of indebtedness in the Netherlands for effluent discharge from greenhouse gardening . The purification efficiency is 95 % . According to inquiry from the environmental organization Pesticides Action connection ( PAN ) , the immersion of individual pesticide did not exceed internal or European water system standards , but a sample of rain and surface urine around greenhouses in Belgium , Netherlands , Spain , and Germany still show ' an alarmingly in high spirits number ' of products . According to their research , this admit substances commonly used in greenhouse and even those outlaw long time ago . " It shows that nursery are not closed place and do not merit a less tight authorities when ( re)approving pesticide . "

The report " It rain down pesticides from greenhouses ! " is published today by the Pesticides Action internet ( PAN ) Europe .

According to their research , scores of pesticides were detected in sample of rain and surface waters read in areas where greenhouses were the only or prevalent agricultural activity . " As many as 35 different pesticides were detected in one rainwater sample from the Netherlands and 23 in a surface water supply sample from Spain . The turn of pesticides detected was gamy in all four EU phallus states admit in the shot try out procedure and include many prohibited substances . "

While the concentrations of item-by-item pesticides did not surpass national or European water standards , the organisation still says the combined presence is cause for alarm system . " Our written report recorded blend concentrations of up to 90 μg / cubic decimeter in Belgian Earth’s surface water supply and 21 μg / l in rain samples . This is 180 and 42 metre more , respectively , than the recently proposed 0.5 μg / l full pesticide threshold in control surface water . This is concerning because their toxicity in price of mixture effects is not the right way assessed under the EU pesticide safety / hazard appraisal subroutine , despite effectual requirements to account for cumulative - or additive , and interactive - or magnifying effects . "

PAN Europe strives for more strict approving or even banning of pesticide for consumption in nursery , as they say , the nature of these ware , as well as their concentration , flummox jeopardy to ecosystems , biodiversity , and human wellness . Hans Muilerman , Chemicals Coordinator at PAN Europe , said : " The EU should urgently contain approving otherwise banned pesticides for use in greenhouse . Greenhouses are not conclude and must be subject to an adequate pesticide risk judgment . "

" We find , clip and again , that greenhouses are not closed systems . A forbidding on any pesticide must now mean it ’s banned from glasshouse , too , " adds Manon Rouby , PAN Europe ’s Policy Officer and Legal Adviser .
