PER CURIAM:


1
This appeal challenges the district court's refusal to permit plaintiffs-appellants to proceed as a class under the provisions of Fed.R.Civ.P. 23(c) (1) to recover damages and obtain injunctive relief from air and noise pollution allegedly caused by defendants-appellees industries' chemical manufacturing activities.

We conclude that our jurisdiction cannot be supported under the "death knell" concept, Korn v. Franchard Corp., 2 Cir. 1971, 443 F.2d 1301, Green v. Wolf Corp., 2 Cir. 1968, 406 F.2d 791, cert. denied 395 U.S. 977, 89 S.Ct. 2131, 23 L.Ed.2d 766, Eisen v. Carlisle and Jacquelin, 2 Cir. 1966, 370 F.2d 119, cert. denied 386 U.S. 1035, 87 S.Ct. 1487, 18 L.Ed.2d 598, or under the so-called "collateral order" exception of the statute, Cohen v. Beneficial Industrial Loan Corp., 1949, 337 U.S. 541, 69 S.Ct. 1221, 93 L.Ed. 1528.  The district court's ruling is not a final judgment under 28 U.S.C.A. Sec. 1291, Gosa v. Securities Investment Company, 5 Cir. 1971, 449 F.2d 1330.


3
Dismissed for lack of jurisdiction.
