Concentrations of major and trace elements in the soils, edible parts of crops and urine of farmers in agroecological communities. The relationship between soil and health is important for populations that depend on the local environment to meet their nutritional needs. This study aimed to evaluate the concentrations of major and trace elements in the soils, edible parts of crops and urine of farmers in agroecological communities. We collected samples of soil, edible parts of crops and urine of farmers and family members in 23 crop fields in agroecological communities from northeast Brazil. These samples were analyzed to concentrations of Al, As, Ca, Cr, Cu, Fe, Hg, Mg, Zn, and Pb in urine and discriminant analysis and principal component analysis were used to assess the data.

Trace Elements in Soils and Plants

Soil is a major source of nutrients needed by plants for growth. The three main nutrients are nitrogen N , phosphorus P and potassium K. Together they make up the trio known as NPK. Other important nutrients are calcium, magnesium and sulfur. Plants also need small quantities of iron, manganese, zinc, copper, boron and molybdenum, known as trace elements because only traces are needed by the plant.

Robin D. Graham, James C. There are similarities between mammals and plants in the absorption and transport of trace elements. The chemistry of trace element uptake from food sources in both cases is based on the thermodynamics of adsorption on charged solid surfaces embedded in a solution phase of charged ions and metal-binding ligands together with redox systems in the case of iron and some other elements. Iron uptake is the most studied of the micronutrients, and divides the plant kingdom into two groups: dicotyledonous plants have a turbo system that is an upregulated version of the constitutive system, which consists of a membrane-bound reductase and an ATP-driven hydrogen ion extrusion pump; and monocotyledonous plants have a constitutive system similar to that of the dicots, but with an inducible system remarkably different that uses the mugeneic acid class of phytosiderophores PS.

Trace Elements in Soil—Plant—Animal Systems discusses the adverse effects or the essentiality of trace elements in soil, plants, and animals under field and laboratory conditions. The book explores the chemistry, biochemistry, and physics of the availability of trace elements to several organisms, as well as their functions in cell metabolism. Organized into six parts encompassing 24 chapters, the book starts with an overview of the chain of events whereby trace elements are released from different soil and rock sources.

The accuracy of the measurements have been evaluated by analyzing a number of plant and soil reference materials, precision have been estimated by triplicate analysis of the sample as well as that of the reference material. The obtained accurate and reliable data of some trace elements on microgram level for plants and soil will serve as baseline values and will be helpful to monitor the changes in the trace element content of soil and plant leaves.

Ноги несли его с такой быстротой, на какую, казалось ему, он не был способен. Когда он влетел во вращающуюся дверь, прозвучал еще один выстрел. Стеклянная панель обдала его дождем осколков.

Trace Elements in Soil-Plant-Animal Systems

Да будь они прокляты, эти криптографы. Ничего не понимают в системах безопасности. Присяга, которую Чатрукьян принимал, поступая на службу в АНБ, стала непроизвольно прокручиваться в его голове. Он поклялся применять все свои знания, весь опыт, всю интуицию для защиты компьютеров агентства, стоивших не один миллион долларов. - Интуиция? - с вызовом проговорил .

Звон колоколов оглушал, эхо многократно отражалось от высоких стен, окружающих площадь. Людские потоки из разных улиц сливались в одну черную реку, устремленную к распахнутым дверям Севильского собора.

Каждой единице информации присваивался уровень секретности, и, в зависимости от этого уровня, она использовалась правительственными чиновниками по профилю их деятельности. Командир подводной лодки мог получить последние спутниковые фотографии российских портов, но не имел доступа к планам действий подразделений по борьбе с распространением наркотиков в Южной Америке. Эксперты ЦРУ могли ознакомиться со всеми данными об известных убийцах, но не с кодами запуска ракет с ядерным оружием, которые оставались доступны лишь для президента. Сотрудники лаборатории систем безопасности, разумеется, не имели доступа к информации, содержащейся в этой базе данных, но они несли ответственность за ее безопасность. Как и все другие крупные базы данных - от страховых компаний до университетов, - хранилище АНБ постоянно подвергалось атакам компьютерных хакеров, пытающих проникнуть в эту святая святых.
