Effect of Silicon on Micronutrient Content in New Potato Tubers.

Since silicon can improve nutrient uptake in plants, the effect of foliar silicon (sodium metasilicate) application on micronutrient content in early crop potato tuber was investigated. Silicon was applied at dosages of 23.25 g Si∙ha or 46.

Assessment of the nutritional safety of new potatoes imported to Poland using an ascorbate-nitrate index.

Background: New potatoes are imported to Poland mainly from the Mediterranean countries. In climate of the Mediterranean Basin potatoes can be grown twice a year. The different environment conditions during plant growth have effect on the tuber quality.

Activity of cesium 137Cs and potassium content in new potatoes imported to Poland.

Background: Potatoes are an important component of the human diet. In addition to components which determine the nutrition and dietary values, potato tubers also contain anti-nutritional substances, inter alia radioactive elements. Natural and artifical radionuclides are released to the environment as a result of antropogenic activity, in a controlled or uncontrolled manner, and they are transferred to the human body through the food chain.

Nitrates and nitrites in selected vegetables purchased at supermarkets in Siedlce, Poland.

Background: Vegetables constitute a vital part of the human diet, being the main source of minerals, vitamins, dietary fibre and phytochemicals. They however, also contain nitrates and nitrites, which adversely affect human health.

Objective: To determine nitrate and nitrite content in selected vegetables purchased at supermarket chains in Siedlce and to assess their impact on consumer health.
