This study was undertaken to determine the concentration of Pb in liver and muscle tissues of Platycephalus indicus fish collected from two creeks Jafari and Behad (Musa estuary, northwestern Persian Gulf) and was conducted to survey influence of total length and sex on accumulation of Pb in fish tissues during Agust 2010. Concentration of Pb in sediments was also measured. Total number of fish...

The environmental changes by human activities lead to contamination of natural ecosystems and agricultural lands to heavy metals such as cadmium (Cd), which enumerates the most important environmental pollutants. This experiment was conducted for study of cadmium and mycorrhizal symbiosis effects on growth and physiological parameters as well as cadmium accumulation in Black seed (Nigella sativ...

a study of physiological responses of different wheat cultivars to saline conditions can lead to an identification of the main mechanisms in salt tolerance. seven bread wheat cultivars differing in salt tolerance with varying ability of sodium accumulation in their different tissues were employed to assess ion distribution and sodium accumulation under saline conditions. ion distribution and na...

Background: The presence of lead in the industrial fumes, sewage, and also in industrial paints, ceramic, and printing materials, make this element as one of the most common environmental contaminant. Lead can enter the body through respiratory and digestive tracts as well as through the skin and with progressive accumulation can have a destructive effect on several organs in the human body. Bl...

Accumulation of Cu, Zn, Cd, and Pb in the sediment of seagrass ecosystems was examined using mesocosm experiments containing Zostera marina (eelgrass) and reference pools. Lead was approximately 20-fold higher in the surface sediment in the eelgrass pool than in eelgrass leaves and epiphytes on the eelgrass leaves, whereas zinc and cadmium were significantly lower in the surface sediment than i...
