since industrial revolution heavy metals such as lead (pb) and cadmium (cd) have been extensively dispersed in environment which, unknown biological effects and prolong biological half-life make them as a major hazard to human health. in addition, the sharp increase in multiple sclerosis incidence rates has been recorded in iran. the propose of this study was to measuring blood lead and cadmium...

Heavy metal contamination in crops is a worldwide problem that requires accurate and timely monitoring. This study is aimed at improving the accuracy of monitoring heavy metal stress levels in rice utilizing remote sensing data. An assimilation framework based on remote sensing and improved crop growth model was developed to continuously monitor heavy metal stress levels over the entire period ...

heavy metals are aggressive environmental pollutants. they are easily taken up by plants and they are strong stress factors for plant metabolisms. heavy metals influence includes also disturbances in plant mineral nutrition by competition with other nutrients. the specific objective of this research work was to study whether elevated cr (vi), cd and pb contamination caused an unbalanced nutriti...

Remote sensing can actively monitor heavy metal contamination in crops, but with the increase of satellite sensors, the optimal scale for monitoring heavy metal stress in rice is still unknown. This study focused on identifying the optimal scale by comparing the ability to detect heavy metal stress in rice at various spatial scales. The 2 m, 8 m, and 16 m resolution GF-1 (China) data and the 30...

The use of remote sensing technology to diagnose heavy metal stress in crops is of great significance for environmental protection and food security. However, in the natural farmland ecosystem, various stressors could have a similar influence on crop growth, therefore making heavy metal stress difficult to identify accurately, so this is still not a well resolved scientific problem and a hot to...

today, biosphere pollution has accelerated strongly with start of industrial revolution by toxicity of heavy metals. one of existing pollution is soil pollution. unfortunately, soil pollution by metals is as intensive environmental stress for plant hence for human. plants, which are able to store heavy metals in their organs, can be used for phytoremediation of polluted soils and utilization of...

Heavy metal (HMs) pollution is currently one of the serious issues for the environment and agriculture as it has a direct impact on the production yield. This situation has gained a rapid momentum in the present era due to the population pressure, industrialization, and various anthropogenic activities which in turn lead to oxidative ...

An effective method to monitor heavy metal stress in crops is of critical importance to assure agricultural production and food security. Phenology, as a sensitive indicator of environmental change, can respond to heavy metal stress in crops and remote sensing is an effective method to detect plant phenological changes. This study focused on identifying the rice phenological differences under v...

Accurate monitoring of heavy metal stress in crops is of great importance to assure agricultural productivity and food security, and remote sensing is an effective tool to address this problem. However, given that Earth observation instruments provide data at multiple scales, the choice of scale for use in such monitoring is challenging. This study focused on identifying the characteristic scal...
