Biomass allocation is an important plant trait that responds plastically to environmental heterogeneities. However, the effects on this trait of pollutants owing to human activities remain largely unknown. In this study, we investigated the response of biomass allocation of Phragmites australis to petroleum pollution by a ¹³CO₂ pulse-labelling technique. Our data show that plant biomass signifi...

An oil spill is the accidental or intentional discharge of petroleum products into the environment due to human activities. Although oil spills are actually just a little percent of the total world oil pollution problem, they represent the most visible form of it. The impact on the ecosystems can be severe as well as the impact on economic activities. Oil spill cleanup is a very difficult and e...

In recent decades petroleum pollution in the tropical rainforest has caused significant environmental damage in vast areas of the Amazon region. At present the extent of this damage is not entirely clear. Little is known about the specific impacts of petroleum pollution on tropical vegetation. In a field expedition to the Ecuadorian Amazon over 1100 leaf samples were collected from tropical tre...

Following a 120-h exposure period to 3 concentrations of oil dispersions (0.022 mg L(-1) , 1.8 mg L(-1) , and 16.5 mg L(-1) , plus controls) generated from a North Sea crude oil and a subsequent 21-d recovery, mortality, and several reproduction endpoints (egg production rates, egg hatching success, and fraction of females participating in reproduction) in Calanus finmarchicus were studied. Con...

Plant-microbe interactions are considered to be important processes determining the efficiency of phytoremediation of petroleum pollution, however relatively little is known about how these interactions are influenced by petroleum pollution. In this experimental study using a microcosm approach, we examined how plant ecophysiological traits, soil nutrients and microbial activities were influenc...

UNLABELLED BACKGROUND Petroleum pollution is a global disaster and there are several soil cleaning methods including bioremediation. METHODS In a field study, fugal strains were isolated from oil-contaminated sites of Arak refinery (Iran) and their growth ability was checked in potato dextrose agar (PDA) media containing 0-10% v/v crude oil, the activity of three enzymes (Catalase, Peroxid...

abstract petroleum pollution is one of the most common and dangerous pollutions that is due to petroleum industries such as refineries, and consequently of oil pipes and tanks leak causing environmental pollutions. one of the newest born technologies in this area is phytoremediation, in which plants are used for decreasing of petroleum pollution. this technology is used for remediation of soil,...

In the Spill o Llibre de les dones, the 15th century writer and physician from Valencia, Jaume Roig, uses the motif of pilgrimage to attack earthly women, particularly women healers. Roig undermines the salutary function of medieval pilgrimage in order to expose worldly women in their effort to harm male pilgrims. Since men cannot rely on earthly women, they must seek a healing encounter with t...

The short-term effects of oil spills on marine species and communities are well known and predictable. However, concerns are often raised about possible longer-term ("sub-lethal") population effects through, for example, low levels of residual oil affecting the ability of certain species to breed successfully. In fact, extensive research and detailed post-spill studies have shown that many comp...
