Abstract Parmotrema austrosinense (Zahlbr.) Hale lichens were collected from the Pretoria central business district (CBD), as well as three sites to the east of Pretoria; the National Botanical Gardens, the CSIR campus and the suburb of Lynnwood, with the aim of utilising these lichens as biomonitors of air quality to determine the effects of the phasing out of leaded petrol and the simultaneous introduction of manganese anti-knock additives to fuel in South Africa. In addition to lichens, roadside dust and soil samples were collected from the CBD and CSIR campus, and all samples were analysed

Abstract The thesis consists of regional forest condition studies, using different biomonitors. Heavy metal deposition was investigated in 1985–2000 on the basis of the heavy metal concentrations (As, Cd, Cr, Cu, Fe, Hg, Ni, Pb, V, Zn) in mosses in Finland. A comparison on the suitability of mosses, epiphytic lichens and pine bark as biomonitors of heavy metals was also carried. Bark was also used to study the dispersal of emissions from the Kola Peninsula into northern Finland. The occurrence of green algae on conifers in Finland was investigated in 1985 and 1995.

Abstract:

Many antrophic activities release pollutants to the marine environment. Among them heavy metals are of great importance, since they are conservative pollutants, which can be accumulated through trophy chains. Sometimes, the liberation to the marine waters is acute and drastic, leading to massive mortalities. However, more often, the liberation is by means of low and chronic concentrations. The main objective of the present thesis is to analyze the sponge responses in face to sublethal concentrations of heavy metals and to determine, if it is possible, whether they can be used as biomonitors of

Abstract:

In assessing the health risks posed from heavy metals in a contaminated site, it is important to determine when the contamination occurred and when the metals become available to the surrounding biota. Trees and plants growing in the vicinity of a contaminated site may provide such a historic record. There have been few studies on their role as biomarkers to identify metal mobility or bioavailability for continuous monitoring purposes. The aim of the study was to evaluate the role of plants as biomonitors for site characterisation and risk assessment purposes and to see if there was any select

Uncertainty is a phenomenon that cannot be avoided in the assessment of environmental impacts, due to the inherent stochasticity of environmental systems, as well as a lack of adequate empirical data related to specific cause and effect relationships. A primary constraint associated with generation of adequate data from experiments is that environmental research is expensive, and conclusive results may take several years to obtain.

Abstract:

Por aproximadamente 40 anos, o Rio Ribeira de Iguape recebeu resíduos da mineração: rejeitos das plantas de concentração mineral (enriquecidos em Cu, Cr, Pb, Ag e Zn) e escórias de uma unidade de metalurgia (enriquecidas em Cu, Zn, Cr, Fe, Pb e As), produzidos e descartados pela empresa Plumbum S/A, localizada em Adrianópolis (Paraná). Para verificar a contribuição destes resíduos na contaminação deste rio, como também identificar a possibilidade de depuração natural ou não no mesmo, definiu-se a necessidade de avaliar três compartimentos: resíduos, sedimentos e organismo biomonitor.

Abstract:

L'exposició a la contaminació ambiental és una de les principals amenaces per a la salut dels ecosistemes i les poblacions silvestres. L'estrès produït per la contaminació pot causar importants alteracions a la fauna, especialment als depredadors com les aus rapinyaires que, d'altra banda, s'utilitzen com espècies sentinelles del seu ecosistema. Comprendre el mecanisme mitjançant el qual els organismes fan front a l'estrès ambiental i s'adapten a un ambient canviant és crucial per a la seva conservació. Amb aquest propòsit, les hormones d'estrès (corticosterona en aus) s'han utilitzat com a bi

Abstract:

Biomonitoring has become an important component in bioassessment programs. It is used to maintain high water quality standards, and determine contaminant levels and biological affects in areas that have been heavily disturbed. The objectives of this research were 1) to improve and apply certain modern biomonitoring techniques and 2) to locate possible contaminant sources affecting the flora and fauna of the Green River and of Mammoth Cave. Actinonaias ligamentina (Lamarck, 1819), a freshwater mussel, was used for interpretation of these impacts as well as refinement of biomonitoring techniques

Abstract:

O presente estudo foi desenvolvido para caracterizar a área de influência dos corredores de tráfego, através do monitoramento da concentração de elementos-traço em cascas de árvores. Amostras (n = 98) de cascas de árvores de diversas espécies foram coletadas em cinco parques urbanos da cidade de São Paulo. Para controle, foram coletadas cascas de árvores numa zona rural de Embu-Guaçu, longe de tráfego ou de indústrias. As concentrações de Ba, Co, Cr, Cu, Fe, Ca, Pb, S e Zn foram determinadas nas amostras de cascas de árvores por espectrometria de fluorescência de raios-X. Amostras coletadas no
