Streszczenie:

Birds have been widely used as bioindicators. In this study we face the use of birds as bioindicators of metal pollution in two different scenarios of contamination: one that takes place in an aquatic environment, the Ebro river basin, and a second that occurs in a terrestrial environment, the Bolivian Andes. In the case of the Ebro river basin, the pollution threat is a factory located at the river bend, close to Flix, that due to its long operational activity and along with the construction of a dam next to the plant around 1960, resulted in the accumulation of 200,000–360,000 tons of in

Streszczenie:

The distribution of heavy metals between soil and soil solutions is a key issue in evaluating the environmental impact of long term applications of heavy metals to land. Contamination of soils by heavy metals has been reported by many workers. Metal adsorption is affected by many factors, including soil pH, clay mineralogy, abundance of oxides and organic matter, soil composition and solution ionic strength. The pH is one of the many factors affecting mobility of heavy metals in soils and it is likely to be the most easily managed and the most significant. To provide the appropriate level of p

The global human population is expected to exceed 9 billion individuals by 2050, putting greater strain on the natural resources needed to sustain such a population. To feed this many people, some expect agricultural production will have to double and agrochemical use will have to increase anywhere from two- to five-fold relative to the turn of the century. Although industrial agriculture has provided many benefits to society, it has caused declines in biodiversity, both directly (e.g., through conversion of habitat) and indirectly (e.g., through contamination of adjacent natural habitats).

Mercury poses a public health burden worldwide. In parts of the developing world, Hg-use during artisanal and small-scale gold mining (ASGM) is pointed at as the source of elevated Hg in the environment. However, Hg from other sources including soil erosion associated with land cover and land-use change (LCLUC) may also contribute to local Hg pollution. </p><p> Stable Hg isotope profiles of sediment cores, surface sediments, and soils from t

Previous research on Honolulu streams indicates that contamination by trace metals from automobile usage is a significant problem, especially Cu (copper), Pb (lead), and Zn (zinc).

Enrichment ratios (ERs) indicated that the Nuʻuanu watershed is significantly polluted in the lower, urbanized reaches, with maximum ER values of 444 (road sediments) and 74 (stream sediments) for Pb.

Anthropocene is the current era in which human activities modify various environmental properties, which have implications for many coastal processes. Anthropogenic stressors increasingly affect coasts and push these environments to a new altered equilibrium state. However, monitoring such pollution is a challenging task because coastal systems are highly dynamic and integrate the physicochemical forces at work on freshwater bodies, estuaries and lagoons with the oceanographic characteristics of adjacent seas.

Throughout the world, increased use of agrochemicals, warrant urgent measures to minimise their impacts on the aquatic environment. Monitoring is the usual practice to identify and quantify pollutants, however, it is an after-the-fact occurrence, and monitoring over large spatial scales is not feasible. Mathematical models provide an alternative to monitoring and can be used both to forecast future pollution and to investigate the impacts of potential control measures. This thesis is therefore focussed on catchment scale modelling of pesticide pollution of rivers. Data from a 142-ha agricultur

Streszczenie:

Thesis (MTech (Horticulture))--Cape Peninsula University of Technology, 2012.<br>The Diep River is approximately 80 km in length and runs through agricultural land and urban parts of greater Cape Town, South Africa before entering the Atlantic Ocean, via an estuary. Generally, metal pollution in South African rivers is not well documented and using plants to monitor metal bioaccumulation is even less documented. The aim of this study was to investigate aluminium, iron, copper and zinc metal pollution in the Diep River and bioaccumulation of these metals in the leaves and stems of the subm
