Effects of insecticides on survival and reproduction of microarthropods in African and European soils

New publication: Effects of insecticides on survival and reproduction of microarthropods in African and European soils

In many parts of Africa, pesticides are used indiscriminately. Yet, ecotoxicological data relevant for the protection of soil organisms have usually been obtained under temperate conditions. In order to assess the effects of three commonly used insecticides (deltamethrin, dimethoate, chlorpyrifos) on microarthropods in African soils, uncontaminated natural soils were collected from Nigeria and Tunisia. In […]

Assessing the long-term effects of the selected nanomaterial titanium dioxide – adaptation of testing procedures

Effects of the nanomaterial titanium dioxide NM-105 were studied in a sediment/water system with Lumbriculus variegatus according to OECD test guideline 225. Test media were prepared by mixing NM105 suspensions and the sediment-overlying water. Nominal test concentrations were confirmed by chemical analysis of Ti concentrations in the test media. Effects of titanium dioxide (NM-105) were […]
