William A. Larson appeals from summary judgment entered in the district court 1 dismissing his claim for damages against Missouri prison officials based upon his alleged excessive exposure to cigarette smoke while imprisoned. For reversal, Larson argues that the district court erred in granting summary judgment, in denying his motion for preliminary injunction, and in granting Gary Kempker, director of the Missouri Department of Corrections’ motion to exclude testimony. We find no reversible error and affirm.
I. Background
In 1982, William A. Larson was convicted of capital murder and sentenced to life imprisonment. In 1997, Larson was transferred to the Crossroads Correctional Center (CCC) where he remains incarcerated. In August 1998, Larson filed a complaint regarding inmate smoking but never received a response. Larson filed a second complaint in November 2000. The second complaint was converted to a grievance and denied. Larson’s appeal was lost, requiring him to refile his appeal. Larson’s appeal was then denied. In September 2001, Larson filed a third smoking complaint, which was denied and converted to a grievancе. The grievance was denied as was Larson’s appeal. Larson then filed this suit in the district court under 42 U.S.C. § 1983 and the Prison Litigation Reform Act, 42 U.S.C. § 1997.
In addition to Kempker, Larson sued George Lombardi, director of the Missouri Division of Adult Institutions, and Michael Kemna, superintendent of CCC (collectively referred to as Kempker). Larson’s suit alleged the defendants did not adequately protect' him from exposure to second-hand smoke. 2 Larson has not been diagnosed with an allergy to environmental tobacco smoke (ETS) or with any current respiratory illness, diseаse or defect. Larson tested negative for coronary artery disease. Larson testified that years ago he was diagnosed as suffering from Asper-ger’s Disorder, making him antisocial and necessitating that he be placed in a one-man cell. However, there is no medical record documentation for Asperger’s Disorder or documentation connecting it with ETS. Larson believes there is such a connection. Larson sought an injunction as well as damages for infliction of cruel and unusual punishment a'nd for denial of due process.
Following discovery, Kempker moved to exclude Larson’s expert, Dr. A. Judson Wells from testifying on the basis that Dr. Wells’ testimony failed to meet the requirements of Federal Rule of Evidence 702 or those of
Daubert v. Merrell Dow Pharmaceuticals, Inc.,
In a single order, the district court granted Kempker’s motion for summary judgment and Kempker’s motion to exclude Dr. Wells’ testimony and denied Larson’s motion to file a second amended complaint and Larson’s preliminary injunction. From that decision Larson appeals.
II. Discussion
A. Standard of Review
We review a district court’s decision to grant summary judgment
de novo.. Bowen v. Mo. Dep’t of Soc. Servs.,
B. Eleventh Amendment Immunity
We first address whether the Eleventh Amendment bars this suit as contended by Kempker against the defendants in their official capacities.

Larson’s original complaint stated that he was suing two of the defendants in their official and individual capacity. However, when Larson filed a First Amended Complaint and added Lombardi as a defendant, the complaint failed to indicate that he was suing the defendants in their individual capacities. Technically, Larson’s complaint had to “contain a clear statement of his wish to sue defendаnts in their individual capacities.”
Egerdahl v. Hibbing Community College,
Here, however, this omission is not fatal to Larson’s claim. In his complaint, Larson named the defendants individually without reference to the State of Missouri. We have held that “[o]ver the years ... important exceptions to state' immunity from suit have bеen recognized which allow citizens to vindicate rights infringed on by the state. If a state official is named as
*940
a defendant instead of the state or one of its agencies, the Eleventh Amendment status of the suit is less straightforward.”
Nix v. Norman,
seeking to impose a liability which must be paid from public funds in the state treasury, ... courts may order injunctions to prevent or remedy a state officer’s conduct.... Courts may also award a wide range of prospective relief which serves to bring an end to a present violation of federal law ... even though accоmpanied by a substantial ancillary effect on the state treasury.
Id. (internal quotations and citations omitted). We hold that the district court had the discretion to order injunctive relief.
C. Denial of Preliminary Injunction on Eighth Amendment Claim
Larson contends the district court misapplied
Helling v. McKinney,
The district court found that Larson failed to meet the objective test and denied his requested injunction. Our review confirms the finding of the district court that Larson failed to put forth objective evidence that he was subjected to unreasonably high levels of ETS. Larson’s expert performed no scientific tests to establish the levels of ETS in Larson’s cell. Furthermore, Larson did not present any other reliable basis to estimate thе levels of ETS to which he is exposed or specific evidence concerning how those levels of ETS would affect his future health. The district court was correct in denying Larson’s motion for a preliminary injunction. The evidence is insufficient to establish Larson was subjected to an unreasonable risk of harm from ETS. Having determined that Larson failed to satisfy the objective element of an Eighth Amendment claim, we need not address the subjective element.
D. Exclusion of Expert Testimony
Next, Larson argues that the district court erred by excluding the testimony of Dr. Wells under Fed.R.Evid. 702.We review a district court’s decision to exclude expert testimony for abuse of discretion.
Meterlogic, Inc. v. KLT, Inc.,
The district court excluded the testimony of Dr. Wells after determining that Dr. Wells did not have the education or training in any field that would permit him to testify about second-hand smoke. The district court stated “[h]e may have read what other experts have written on the subject, but this does not qualify him to speak with authority on the subject; at best, all he can say is what experts in the field have written on the topic.” We hold the district court erred in excluding Dr. Wells’ testimony.
Admission of expert testimony is guided by the principles of
Daubert v. Merrell Dow Pharm., Inc.,
Scientific “implies a grounding in the methods and procedures of science. Similarly, the word knowledge connotes more than subjective belief or unsupported speculation.”
Id.
at 590,
A key question in determining whether knowledge is scientific is whether a theory or. technique can or has been tested.
Id.
at 593,
The district court did not believe that Dr. Wells’ testimony would aid the jury becausе he “cannot describe the specific health effects of varying levels of ETS,” nor can he testify “about the levels of ETS to which [Larson] is exposed.” The court found that Dr. Wells’ calculations and conclusions were not accuraté and therefore not based “оn sufficient facts or data as Rule 702 requires.” Finally, the district court concluded it would have granted Kempker’s motion for summary judgment even considering Dr. Wells’ testimony because the testimony failed to “provide the jury with the information necessary to permit a verdict in [Larson’s] favor and would not create a factual dispute sufficient to preclude summary judgment.”
“As a general rule, the factual basis of an expert opinion goes to the credibility of the testimony, not the admissibility, and it is up to the opposing party to examine the factual basis for the opinion in cross-examination.”
Hose v. Chicago NW Transp. Co.,
*942 We hold that Dr. Wells was qualified as an expert to testify regarding the deleterious health effects of ETS. Dr. Wells has over twenty-three years of ETS experience. He has a Ph.D. in physical chemistry from Harvard University and was a principal consultant to the Environmental Protection Agency (EPA). Dr. Wells authored the EPA’s 1992 report on secondhand smoke and respiratory diseases, including lung cancer. Dr. Wells has served as a consultant to the Occupational Safety and Health Administration and was one of three United States experts to advise the Ontario Tobacco Research Unit of the University of Toronto in its report “Protection from Involuntary Exposure to Tobacco Smoke in Ontario: a Review of the Evidence, for the Ontario Ministry of Health.” He has testified before the Subcommittee on Natural Resources, Agriculture Research and Environment and the Committee on Science and Technology, United States House of Representatives, and before a Delaware legislative committee regarding second-hand smoke. Additionally, Dr. Wells has written scientific articles that have been cited by other experts.
Although we hold that the district court abused its discretion by not admitting Dr. Wells’ expert testimony, the error is nonetheless harmless because Larson still cannot meet Helling’s objective requirement of showing that he was exposed to unreasonably high levels of ETS and that it poses a risk that, in the Supreme Court’s words, “is not one that today’s society chooses to tolerate.”
III. Conclusion
We affirm the decision of the district court granting of summai-y judgment in favor of Kempker.
Notes
. The Honorable Ortrie D. Smith, United States District Judge for the Western District of Missouri.
. CCC has a policy of prohibiting smoking inside any building, including inmates’ cells. Records show that between Septеmber 2001 and December 2003, 126 conduct violations for smoking were issued to prisoners. Since December 1999, Larson has been housed in a two-man cell with an inmate who does not smoke. Some of Larson's prior cellmates did smoke. The evidence fails to show when Larson wаs housed with the various cell mates who smoked. The evidence indicates that the prohibition on smoking is not strongly enforced or is often circumvented.
. Kempker argues that the Eleventh Amendment prohibits the present suit because the state has not consented to 'be sued. Eleventh Amendment immunity bars a § 1983 lawsuit against a state agency or state official in official capacity even if the entity is the moving force behind the deprivation of the federal right.
