Mit pubmed-Suche (ich glaube, das ist dasselbe wie medline) und den Stichwörtern "hair-coloring brain tumor" habe ich noch ein bisschen was gefunden.
In dem oben angegebenen Artikel steht extra, dass sich für andere künstliche Haarfarben ausser Schwarz kein erhöhtes Risiko ergeben hat. Man müsste also die "schwarzen" rausrechnen, dann könnte man in dem folgenden Artikel vielleicht in den Daten etwas finden. Zudem geht es um die Gefährdung der Kinder in der Schwangerschaft, und das ist doch recht indirekt.
Zum Thema Nitrosamine: Es muss irgendwas sein, was den Fettstoffwechsel im Gehirn richtig stört, wie z.B. Benzin oder Terpentin oder andere Lösemittel. Trifft das auf die Nitrosamine zu?
Wenn du den obigen Artikel liest, dann geht es eher um die Kohlefarben, die in Verdacht sind.

We conducted a matched case-control study to investigate risk factors for the two most common types of brain tumors in children, astrocytic glioma and primitive neuroectodermal tumor (PNET). Since the study focused on gestational exposures, we restricted it to young children because these exposures would be expected to act early in life. Parents of 155 astrocytic glioma cases, 166 PNET cases, and controls identified by random digit dialing completed telephone interviews. Few associations occurred with the hypothesized risk factors, which were gestational exposure to alcohol, hair coloring products, farms, and substances containing N-nitroso compounds (passive smoking, makeup, incense, new cars, pacifiers, baby bottles, beer). Of the products studied that contain N-nitroso compounds, only beer was associated with a significantly increased risk of either tumor type [odds ratio (OR) for PNET = 4.0; 95% confidence interval (CI), 1.1-22.1; P = 0.04]. Elevated ORs for PNET were observed for farm residence of the mother during the pregnancy (OR = 3.7; 95% CI, 0.8-23.9; P = 0.06) and of the child for at least a year (OR = 5.0; 95% CI, 1.1-46.8; P = 0.04). Significant associations with astrocytoma were observed for mother's use of kerosene (OR = 8.9; 95% CI, 1.1-71.1; P = 0.04) and birth by Caesarean section (OR = 1.8; 95% CI, 1.1-3.2; P = 0.03). History of miscarriage was associated with a lower risk of PNET (OR = 0.5; 95% CI, 0.3-0.9; P = 0.02).(ABSTRACT TRUNCATED AT 250 WORDS)
