Effekter af pyrethroidet lambda-cyhalothrin på biologisk struktur, funktion og rekolonisering i vandløb
Bilag C
Taxon sammensætningen af smådyr i bladpakker udlagt i Stavis Å på dag 0. Halvdelen af de udlagte bladpakker var forud for udlægningen behandlet med lambda-cyhalothrin (5,0 µg l-¹) i en periode på 90 min.; den øvrige halvdel af bladpakkerne var ubehandlede (kontroller). De udlagte prøver blev indsamlet efter hhv. 3, 7, 15, 30 og 60 dage. Tallene angiver gennemsnitligt antal individer pr. bladpakke (N=10).
