    加拿大DSL清單修訂,涉及145種聚合物(附完整清單)

    2023916日,加拿大政府發布了一則通知,根據《加拿大環境保護法》的規定,擬對加拿大本國物質清單(DSL)進行修訂,將在145種聚合物的物質標識符中添加字母“P”。此修訂提案目前正處于意見征詢期,將持續120天。

    背景

    《加拿大本國物質清單》(DSL)記錄了在加拿大以商業規模生產或進口的物質清單。未列入DSL清單的物質被視為新化學物質。根據《加拿大環境保護法》,在對其進行人類健康和環境的潛在影響評估之前,新化學物質不得進口至加拿大或在加拿大制造。新化學品和聚合物的通報要求在《新物質通報法規(化學品和聚合體)》中有詳細規定。

    一般情況下,DSL清單上的化學物質不受通報的約束,但當DSL清單上某一化學物質的物質標識符后面附帶監管標志(即字母“S”“S prime”“P”)時,在某些情況下,該物質將受到通報的約束。

    字母“P”的含義:

    字母“P”表示這些聚合物經過評估,符合法規中降低法規要求(RRR)聚合物的標準。符合降低法規要求(RRR)聚合物標準的物質被認為是低關注度的,其監管要求會比不符合降低監管要求(非RRR)的聚合物要少。

    修訂原因:

    目前,不符合RRR聚合物標準的這些聚合物的任何形式都不需要根據法規進行通報。因此,擬議在這些聚合物的物質標識符中添加字母“P”,以明確只有RRR形式的這些聚合物根據其評估包含在DSL清單中,而非RRR形式的并不包括在內。添加字母“P”將允許在其進口或在加拿大制造之前對不符合RRR聚合物標準的這些聚合物的任何形式進行環境和人類健康風險評估。

    物質名單:

    一、建議對國內物質清單(DSL)第1部分進行修訂,在以下物質標識符中添加字母“P”:
