“…High N0 3 -contents in spinach were found with low light intensities, with low soil-moisture contents, and with high temperatures. NO,-contents increased with increasing K-dressing (less so with KCl than with K. 2 SOA but decreased with increasing soil pH. In pot experiments, positive results were obtained with sulphur-coated urea, with farmyard manure and with pigmanure slurry.…”

3. Gezien de relatief grote spreiding in nitraatgehalten van b.v. spinazie mogen stikstofbemestingsadviezen die erop gericht zijn het overschrijden van een bepaald nitraatgehalte in het geoogste gewas te voorkomen niet gebaseerd worden op de gemiddelde nitraatgehalten die in bemestingsproeven per stikstoftrap worden gevonden.Dit proefschrift.4. Verschuiving van de oogst van spinazie van 's ochtends vroeg naar een later tijdstip op de dag leidt niet noodzakelijkerwijs tot lagere nitraatgehalten en biedt in verband met de verdere verwerking van het produkt eerder na-dan voordelen.5. De overwegend hoge nitraatgehalten van kasgroenten in de wintermaanden zijn eerder een gevolg van de heersende lichtomstandigheden en het kasklimaat dan van het gevoerde bemestingsbeleid.6. In het kader van de nitraatproblematiek is het aanbevelen van een gevarieerde voedselkeuze en het opstellen van richtlijnen ten aanzien van het bewaren en bereiden van bepaalde groenten vooralsnog zinvoller dan het aan een maximum binden van het nitraatgehalte van een aantal 'probleem'groenten.7. Bij de huidige stand van kennis omtrent het verband tussen voeding en kanker is het opstellen van globale richtlijnen ten aanzien van voedselbereiding en -gebruik juister dan het selectief uitsluiten dan wel aanbevelen van bepaalde voedingsmiddelen. page 55, heading of Table 11: read "on" for "in" page 61, equation in section 5.4.1: read "(0-60 cm)" for "(6-60)"and "(0-6 cm)" , "harvested" for "havested"Woord vooraf Een speciaal woord van dank wil ik richten tot de heer Matser voor de voortreffelijke wijze waarop hij het tekenwerk heeft verricht.Alle anderen die op een of andere wijze aan het onderzoek hebben bijgedragen en hier niet met name zijn genoemd wil ik bij deze ook bedanken.Tenslotte wil ik alle instellingen die faciliteiten hebben geboden om de in dit proefschrift beschreven proeven uit te voeren hartelijk danken.

“…Nitrates are normal constituents of plant materials; there is a considerable amount of analytical data in the literature (Achtzehn and Hawat, 1969;Ashton, 1970;Fogden and Fogden, 1969; Jackson et ai, 1967; Rooma, 1971) on average values and ranges for many of our foodstuffs, including prepared infant foods. Of the common vegetables beets, celery, endive, kale, radishes, lettuce, spinach, turnips, and broccoli are usually reported to exceed 1000 ppm of nitrate (fresh basis), and infant foods containing these vegetables may be correspondingly high in nitrate.…”

“…We estimated the nitrate and nitrite contents of the food groups asked on the NCI DHQ based on a literature review of published studies and reports. We used twenty-six studies or reports published between 1967 and 2008 ( 1 , 23 , 25 , 26 , 35 – 56 ) (see online supplementary material, Table S1). This range of publication years was chosen based on the time frame of our dietary intake assessment, particularly because the allowed levels of added nitrate and nitrite in processed meats have changed in past decades.…”

Objective Nitrate and nitrite are probable human carcinogens when ingested under conditions that increase the formation of N-nitroso compounds. There have been limited efforts to develop US databases of dietary nitrate and nitrite for standard FFQ. Here we describe the development of a dietary nitrate and nitrite database and its calibration. Design We analysed data from a calibration study of 1942 members of the NIH–AARP (NIH–AARP, National Institutes of Health–AARP) Diet and Health Study who reported all foods and beverages consumed on the preceding day in two non-consecutive 24 h dietary recalls (24HR) and completed an FFQ. Based on a literature review, we developed a database of nitrate and nitrite contents for foods reported on these 24HR and for food category line items on the FFQ. We calculated daily nitrate and nitrite intakes for both instruments, and used a measurement error model to compute correlation coefficients and attenuation factors for the FFQ-based intake estimates using 24HR-based values as reference data. Results FFQ-based median nitrate intake was 68·9 and 74·1 mg/d, and nitrite intake was 1·3 and 1·0 mg/d, in men and women, respectively. These values were similar to 24HR-based intake estimates. Energy-adjusted correlation coefficients between FFQ- and 24HR-based values for men and women respectively were 0·59 and 0·57 for nitrate and 0·59 and 0·58 for nitrite; energy-adjusted attenuation factors were 0·59 and 0·57 for nitrate and 0·47 and 0·38 for nitrite. Conclusions The performance of the FFQ in assessing dietary nitrate and nitrite intakes is comparable to that for many other macro- and micronutrients.
