MEMORANDUM **

California state prisoner Clifford L. Jackson appeals pro se from the district court’s judgment dismissing his 42 U.S.C. § 1983 action alleging unconstitutional conditions of confinement arising from asbestos exposure. We have jurisdiction under 28 U.S.C. § 1291. We review de novo dismissal for failure to state a claim. Cousins v. Lockyer, 568 F.3d 1063, 1067 (9th Cir. 2009). We affirm.

The district court properly dismissed Jackson’s 42 U.S.C. § 1983 claims against all defendants because Jackson failed adequately to allege physical injury and thus his claim for damages was barred under *120 the Prison Litigation Reform Act. See 42 U.S.C. § 1997(e)(e); see also Oliver v. Keller, 289 F.3d 623, 625-28 (9th Cir. 2002) (the physical injury requirement applies to pre-trial detention claims and requires more than de minimis physical injury).

We do not consider Jackson’s contentions regarding judicial bias because they were not raised in his opening brief. See Brown v. Cal. Dep’t of Corr., 554 F.3d 747, 752 n. 3 (9th Cir. 2009) (issues not raised in the opening brief are waived). We do not consider Jackson’s contentions related to the Comprehensive Environmental Response Compensation and Liability Act and other claims not raised before the district court. See Campbell v. Burt, 141 F.3d 927, 931 (9th Cir. 1998) (issues not raised before the district court are waived on appeal).

We have reviewed Jackson’s remaining contentions and find them unpersuasive.

AFFIRMED.
