Chironomus

Sediment Toxicity. Because of their low solubiUty ia water and lipophilic nature, phthalates tend to be found ia sediments. Unfortunately httle work has previously been carried out on the toxicity of phthalates to sediment dwelling organisms. Eor this reason ECPI has commissioned some sediment toxicity studies designed to measure the effect of DEHP and DIDP ia a natural river sediment on the emergence of the larvae of the midge, Chironomus riparius. [Pg.133]

Gertain cells of insects, eg, Chironomus, contain giant chromosomes that have been repficated for ten cycles without separation of daughter chromatids. These copies of DNA fine up side by side in precise register and produce a banded chromosome containing regions of condensed chromatin and fighter bands of... [Pg.316]
