چکیده
What a life! No end of changing and building up and pulling down again and jumping about. Such a lot of work may turn out to be really harmful. Oh, I'm dejected just to think of all the people who work and buzz and bumble about, and what it all leads to. I had a cousin once who studied trigonometry until his whiskers drooped, and when he had learnt it all a Groke came and ate him up. Yes, so wise he was while lying in the Groke's stomach!

Impact of pulp and paper mill effluent on egg hatchability of pike (Esox lucius L.).
Toxicants affect reproduction often at concentrations well below lethal levels. Also, the acidification of fresh waters has been shown to cause extinction of teleost fish populations usually through a failure of recruitment from younger generations. Both field and laboratory studies have documented that the greatest susceptibility to low pH occurs in the early developmental stages (e.g. Lee et ...

متن کاملBiological activity of bleached kraft pulp mill effluents before and after activated sludge and ozone treatments.
Eucalyptus bleached kraft pulp production, an important sector of the Brazilian national economy, is responsible for generating large volume, high pollutant load effluents, containing a considerable fraction of recalcitrant organic matter. The objectives of this study were to quantify the biological activity of the effluent from a eucalyptus bleached kraft pulp mill, characterize the nature of ...
متن کاملEffect of pulp and paper mill effluent (BKME) on physiological parameters of roach (Rutilus rutilus) infected by the digenean Rhipidocotyle fennica.
Physiological parameters were measured after experimental infection of roach (Rutilus rutilus L.) with Rhipidocotyle fennica Gibson, Valtonen et Taskinen, 1992 (Digenea) cercariae. The fish were caught from two lakes: a eutrophic bleached kraft mill effluent (BKME)-contaminated lake and an oligotrophic unpolluted lake. The intensity of infection was followed up to 10 days post infection (p.i.) ...
