The German government has denounced experiments funded by German carmakers in which humans and monkeys reportedly inhaled diesel exhaust fumes.
German media say the health impact research was done by EUGT, a body funded by Volkswagen, Daimler and BMW.
On Thursday the New York Times reported that the EUGT research was designed to counter a 2012 decision by the World Health Organization to classify diesel exhaust as a carcinogen.
It said that in 2014, EUGT had exposed 10 monkeys to fumes - in an air-tight chamber - from several cars, including a diesel VW Beetle. The testing took place at a lab in Albuquerque, New Mexico.
Then at the weekend Germany's Stuttgarter Zeitung and SWR radio reported that 19 men and six women had inhaled diesel fumes in another EUGT experiment.
During a month of tests at a lab in Aachen, west Germany, they were exposed to various concentrations of diesel fumes, which contain toxic nitrogen oxides (NOx). The BBC has not seen the study itself, but German media say it was published in 2016.
