The toxicity of 78 chemicals and pesticide formulations against the bleak, Alburnus alburnus (Pisces) and the harpacticoid Nitocra spinipes has been tested. The results are expressed as the 96 hr LC(I) 50 i.e. the initial concentration of a substance killing 50 per cent of the test organisms during 96 hours. Among the compounds tested are inorganic and organic compounds (metal salts, solvents and a few more complex compounds such as organotin compounds), pesticide formulations and other industrial chemicals (PCB-substitutes, phthalic acid esters and polychlorinated paraffins). 相似文献

Studies on the effects of a warm sea-water effluent under laboratory conditions required a technique for rearing batches of shipworm larvae from settling stage to maturity, and a way of radiographing adults that would picture them fully extenbed within their tunnels. Ways of infesting small pieces of spruce with the newly-released larvae of Lyrodus pedicellatus Quatrefages, and of radiographing them (enelosed in plastic bags full of artificial sea water) are described in detail, and the fate of a single generation is followed when infested pieces were kept in artificial sea water at two different temperatures. Using these techniques, it was found that the etenidia do not rotate during tunnelling, and that L. pedicellatus depends upon the wood-softening activities of micro-organisms to be able to stay within the wood. 相似文献

2010年2月20日傍晚,山西省晋中、太原、吕梁、长治、阳泉等地相继出现市民顶着寒风走上街头"等地震"的事件,起因则是源于一条网络上流传当地要发生地震的谣言。透过此事我们不难看出谣言只是导火索,公众对于地震和地震预报缺乏科学的认识,以及近年来世界各地频发的大地震给老百姓心中留下的阴影,恐怕才是这场闹剧真正的"炸药包"。近期我们就此事件特别采访了中国地震局地质研究所高建国研究员以及中国地震台网中心孙士鋐研究员,请他们谈谈透过"山西地震谣言"看地震预报与近期地震活动情况。 相似文献
