Trace Element Composition in Forage Samples from a Military Target Range, Three Agricultural Areas, and One Natural Area in Puerto Rico

چکیده
Information about trace element composition in vegetation from tropical environments is scarce. Trace elements were evaluated on vegetation samples collected at the Atlantic Fleet Weapons Training Facilities (AFWTF) in Vieques, agricultural areas in Vieques and mainland Puerto Rico, and at the Guánica State Forest. Analyses were conducted using atomic absorption after dry-ashing of samples and extraction with acid. Crops in Vieques contained more lead (p < 0.05) and cadmium (p < 0.10) than in mainland Puerto Rico. Similar results were observed for lead and cobalt in Syringodium filiforme, Calotropis procera, and Sporobolus virginicus from the AFWTF. The presence of similar trace element profiles in distant terrestrial and marine plant species suggests the presence of different environmental conditions.

Longitudinal survey of lead, cadmium, and copper in seagrass Syringodium filiforme from a former bombing range (Vieques, Puerto Rico)
Trace element composition in plant biomass could be used as an indicator of environmental stress, management practices and restoration success. A longitudinal study was conducted to compare Pb, Cd, and Cu content in seagrass Syringodium filiforme collected at a former bombing range in Puerto Rico with those of a Biosphere Reserve under similar geoclimatic conditions. Trace elements were measure...
متن کاملTrace Elements Analysis in Forage Samples from a US Navy Bombing Range (Vieques, Puerto Rico)
Plants are good environmental sensors of the soil conditions in which they are growing. They also respond directly to the state of air. The tops of plants are collectors of air pollutants, and their chemical composition may be a good indicator for contaminated-areas when it is assessed against background values obtained for unpolluted vegetation. Both, aquatic and terrestrial plants are known t...

Background and Objective: Rangeland forage is the main source of feed for sheep and goats in many countries and the concentration of heavy metals in these plants is very important. Bushehr province is also affected by environmental pollution due to its proximity to the Persian Gulf, the occurrence of different wars and the existence of different oil and gas resources. The environment and rangel...

Three grass species, Agropyron desertorum (Agde) and Agropyron elongatum (Agel) and recently, Bromus tomentellus (Brto) are mainly used for range improvement as mixed seeding in semi-arid areas of Iran. Because there is little information about management of these grasses, this study was conducted at the Sisab Research Station in northern Iran to evaluate their responses to grazing management a...
