Monitoring of heavy metals in agricultural soils of the Republic of Khakasia

Iron (Fe) is one of many heavy metals that is corrosive resistant, dense, and has a low melting point. If accumulated in the body, the metal can cause some medical conditions, such as irritation to skin and eyes, breathing problems, and in the long term, cancer. This research aims to know generally the spread of metallic iron (Fe) in the river Pasar in Belangwetan, Klaten. This study was conducted using an observational method in which researchers did not examine the effects of interventions. Sampling was done using purposive sampling method taken from three points, namely the upper, middle, lower. Determination of iron levels by Atomic Absorption Spectrophotometer (AAS) obtained a positive result, and the data was processed using SPSS to determine the Mean and Standard Deviation. Of the research result, it could be known the Mean score was 2.33 ppm and SD was 0.0352. The result of this research indicated that the levels of iron in the river Pasar in Belangwetan were 2.33 ppm. It means that the levels violate the regulation of the Minister of Health of the Republic of Indonesia, which is not more than 1mg/L (1ppm) in the clean water

The Republic

Global climatic changes have a negative impact on the development of all sectors of the economy, including agriculture. However, the very production of agricultural products is one of the most important sources of greenhouse gases entering the atmosphere. Taking into account the need to reduce the “carbon footprint” in food production, a special place is occupied by the analysis of the volume of greenhouse gas emissions and the development of measures for their sequestration in agriculture. One of the main directions for reducing emissions and immobilizing greenhouse gases is the development of special techniques for their sequestration in the soil, including those used in agriculture. Adaptation of existing farming systems for this task will significantly reduce the “carbon footprint” from agricultural production, including animal husbandry. The development of carbon farming allows not only to reduce greenhouse gas emissions, but also to significantly increase the level of soil fertility, primarily by increasing the content of organic matter in them. As a result, it becomes possible, along with the production of crop production, to produce “carbon units” that are sold on local and international markets. The paper analyzes possible greenhouse gas emissions from agriculture and the potential for their sequestration in agricultural soils. The role of various elements of the farming system in solving the problem of reducing the “carbon footprint” is considered and ways of developing carbon farming in the Republic of Tatarstan are proposed

Agricultural management with chemicals may contaminate the soil with heavy metals. The objective of this study was to apply Principal Component Analysis and geoprocessing techniques to identify the origin of the metals Cu, Fe, Mn, Zn, Ni, Pb, Cr and Cd as potential contaminants of agricultural soils. The study was developed in an area of vineyard cultivation in the State of São Paulo, Brazil. Soil samples were collected and GPS located under different uses and coverings. The metal concentrations in the soils were determined using the DTPA method. The Cu and Zn content was considered high in most of the samples, and was larger in the areas cultivated with vineyards that had been under the application of fungicides for several decades. The concentrations of Cu and Zn were correlated. The geoprocessing techniques and the Principal Component Analysis confirmed the enrichment of the soil with Cu and Zn because of the use and management of the vineyards with chemicals in the preceding decades.
