Analisi delle Acque
Per quanto riguarda l'acqua potabile i limiti di legge sono 0,1 mg / l per ogni pesticida o 0,5 mg / l considerando la somma di tutti i pesticidi (Dir. 2009/90/CE).
Per le acque superficiali, in relazione ai tipi di pesticidi, i valori variano tra 0,3 mg / l (es. Chlorpyrifos) a 4,0 mg / l (es simazina).
I limiti di legge per gli antiparassitari nei prodotti alimentari variano in relazione al tipo di cibo e al tipo di pesticida, con valori compresi tra i 50 mg / kg (ad esempio il latte) a 100 mg / kg (frutti).
