由于环保压力和疲软的锡价，造成了一些锡冶炼厂停业，而那些还在继续生产的冶炼厂一般依靠收高品位的锡精矿来满足环保要求，以便走出经济困境。卡农（Ｃａｍｏｎ）管理机构成功地走在了市场变化的前面，并努争取生产更纯的锡精矿。在过去的１２年期间，该选矿厂的细粒锡石精矿品位从含锡５％提高到了６０％，如果锡精矿品位未能提高，则该公司就不可能在此期间继续推其产品。

A significant increase of all pro-inflammatory cytokines vs basal levels was observed in the supernatant after 24 h of whole blood cultures in patients, but not in controls. In contrast, IL-10 increased significantly in the supernatant of cultures only in patients with mild AP. Cells showed a statistically significant functional reserve for all IL in patients with mild, but only for pro-inflammatory cytokines in patients with severe ***: A marked activation of immune system may be observed in patients with AP, being balanced between pro- and anti-inflammatory cytokines in patients with mild but not severe AP. A reduced functional reserve for the synthesis of IL-10 may be observed in patients with severe AP, which might lead to a worst prognosis.

Other crises, for instance at the end of the Toarcian （-180 My） correspond to a minor extinction. Nevertheless, all major （and many secondary） mass extinctions are correlated with
