毒理性

• 非人类毒性摘录

鸟对用味道驱避剂——醋酸铜处理的食物的反应各不相同，这减少了被圈养且容易获得无限替代食物的鸟所消费的处理食物的量，尽管醋酸铜对自由觅食的鸟无效。一旦醋酸铜从食物中移除，食物消耗量就会恢复正常。

Birds varied in their response to food treated with a taste repellent cupric oxalate /which/ reduced the amt of treated food consumed by captive birds having easy access to unlimited alternate food supplies, although cupric oxalate was ineffective against free ranging birds. Once cupric oxalate /was/ removed from food, food consumption returned to normal.

  We present a systematic study of a mild approach for the activation of metal oxides, involving reactivity and self-assembly in the solid state, which enables their solvent-free chemical separation and direct solvent-free and low-energy conversion into coordination polymers and open metal–organic frameworks (MOFs). The approach is inspired by geological biomineralization processes known as mineral weathering
