For the record

摘要

1.Due to an editing error, we cited Tamara Galloway's paper in Environmental Health Perspective (DOI: 10.1289/ehp.l002367) as a source for the average exposure for BPA. In fact, this paper reports her team's results for endocrine changes in men exposed to the chemical (23 October, p 26). 2.The toxic red mud that escaped a Hungarian mine contained calcium hydroxide, not oxide as we stated (16 October, p 6). 3.We placed New Orleans in entirely the wrong place in the map that accompanied our article on the aftermath of the Deepwater Horizon oil spill (9 October, p 8). The city is actually on the Mississippi river and much closer to the coast.
