Residents and former residents at the Love Canal toxic-waste site in Niagara Falls, N.Y., are no more likely to have suffered chromosomal damage than residents elsewhere in the city, a Government study concluded today. The study, conducted by the Centers for Disease Control in Atlanta and two major national laboratories, contradicted a disputed 1980 study that spread fear among the residents and led to the removal of hundreds of families to protect their safety. The latest study found ''no increase in abnormalities'' among 46 residents or former residents of the area surrounding the canal compared to 50 residents of a control area roughly a mile away. ''This suggests that no specific relationship existed between exposure to chemical agents in the Love Canal area and increased frequency of chromosome damage,'' the study asserted.

An article in Business Day on May 7 about oil exploration attributed to the wrong Phillips Petroleum official a remark about the ''investment climate most attractive'' for exploration projects. The speaker was Edward Morse, director of international affairs for Phillips.

The House of Representatives voted overwhelmingly today to repeal the withholding of taxes from dividends and interest payments. Despite the vigorous opposition of both the Reagan Administration and Speaker of the House Thomas P. O'Neill Jr., Democrat of Massachusetts, the repeal bill passed by a vote of 382 to 41, a margin that would be sufficient to override a veto by President Reagan. The President has threatened in the past to veto any attempt to repeal or postpone the withholding, which is to go into effect July 1. But at his news conference last night, Mr. Reagan stopped short of repeating this threat. ''I'm going to wait and see what they come up with up there on the Hill,'' he said.

After President Reagan lobbied lawmakers with last-minute phone calls, the MX missile narrowly survived another test vote in Congress today and headed for a showdown on the floor of the House and Senate. The House Appropriations Committee voted, 30 to 26, in favor of a resolution that would free $625 million for development and testing of the missile that Congress blocked last year. Most politicians expect the funds to be released, but the outcome is by no means settled. After the committee action, Representative Norman D. Dicks, a Washington Democrat who supported the missile, said, ''The closeness of the vote clearly indicates that the Administration has got a lot of work to do on Capitol Hill.''
