The articles in this issue take us from the antebellum United States to a Soviet museum in Chelyabinsk in the wake of World War II, from the shores of a Guatemalan lake to ballast piles along Canada’s eastern seaboard. Along the way, readers encounter toxic legacies and courtroom drama. The issue begins with a forum on toxics and toxicants organized by Iris Borowy. Originally slotted for the April issue, production complications delayed its publication until now. Drawing together articles that span four continents, the forum underscores just how difficult it is to assign blame or trace causality in an increasingly toxic world. It is followed by five original articles that challenge readers to rethink some untested assumptions.

本期文章将我们从内战前的美国带到了二战后车里雅宾斯克的苏联博物馆，从危地马拉湖岸到加拿大东海岸的压载桩。一路上，读者会遇到有毒的遗产和法庭戏剧。问题始于 Iris Borowy 组织的关于毒物和毒物的论坛。最初定于 4 月发行，生产复杂性将其出版推迟到现在。该论坛汇集了跨越四大洲的文章，强调了在一个日益有毒的世界中归咎于或追踪因果关系是多么困难。接下来是五篇原创文章，挑战读者重新思考一些未经检验的假设。
