Two youngsters born after 1997, will not be able to sue the authority because Judge Mr Justice Akenhead ruled there was no negligence after this time.
This is the first time that, following the negligent release of toxic material into the atmosphere, a court has found that this material can be inhaled and ingested by pregnant women and is capable of causing serious birth defects to their children.

The judge wholey accepted the claimants' parents' account of the conditions in Corby during the works to redevelop the former steal works site.
He described the parents as wholey honest, giving their evidence in a dignified way.
Corby Council had denied that it was negligent during the works at Corby's former British Steel plant between 1985 and 1999 and that there was a link between the removal of waste to a quarry north of the site and deformities affecting hands and feet.
Council chief executive Chris Mallender said: "We are obviously very disappointed and very surprised at the outcome of this trial.
"Our position has always been that there was no link between the reclamation work that was carried out in Corby in past decades and these children's birth defects. That is still our position."
He said the council recognised mistakes were made and accepted some of the criticism but said they had still not seen evidence to confirm a causal link between the work and the defects.
He added: "However, now is not the time for a knee-jerk reaction.
"In the next few days we will be reading the lengthy judgment very carefully and talking to our legal advisers before we decide what our next steps should be."
The legal bill for the council so far has been £1.9million but the authority now faces a £4.7million bill from the claimants' legal teams.
A decision over whether to appeal the decision will be made by the full council at a later date.
In a statement issued after today's judgment, the council's legal representatives Berrymans Lace Mawer said they were surprised by the findings of the court.
The statement said they were asked to advise on an appeal but had over 400 pages of judgment to review and also their client, Corby Borough Council, had to consider its position. The firm said it would be a few weeks before it has instructions.
The statement added: "There are however some clear points to note at this stage.
"The case involves reclamation work going back to the 1980s. The judge concluded that this contamination affected pregnant women. A child, so affected, has 21 years from birth to make a claim and thus any work since the late 1980s which has not met the standard of care indicated in this judgment could be challenged in this way.
"For both local authorities and developers alike this is a significant concern because the standard of care has been drawn very highly, and could cause a rethink of the way that reclamation is carried out in the UK even though the facts of the case are historic."
The claims have been described as the British Erin Brockovich and the ruling is considered to be a land mark one.
In his lengthy judgment - which ran to 919 paragraphs - the judge said there was a "statistically significant" cluster of birth defects between 1989 and 1999. Click here to read more.
