Abstract:

Organochlorine pesticides (OCPs) were extensively applied in agriculture, industry and public health programs for decades. Based on the persistence and the lipophilicity of OCPs, these chemicals are ubiquitous in the environment and can be accumulated in fatty tissues of animals through the food chain. Even being restricted for years, OCPs are still detected in human bodies. In this thesis, analytical methods for the determination of OCPs were developed and applied for the analysis of cord serum samples. The evaluation of prenatal exposure to OCPs and its effects on birth outcomes as well as t

Abstract:

The Trinity River passes through the Dallas-Fort Worth metroplex receiving point and non-point source contaminant loadings. Lepomis spp. were collected at twelve sampling locations in the Trinity River in August 1987 and September 1988 and analyzed for organochlorine pesticides and heavy metals. Results from the study were compared to existing U.S. FDA action and tolerance levels, LC50s, and historical data. Various longitudinal trends and some concentration patterns were observed. Continual study of pesticide and metal body burdens in fish allow testing for trends, and thereby, lead to a bett

Abstract:

In the past, it was widely assumed that deep drainage and the resultant movement of salts, nutrients and organochlorine pesticides was negligible in Vertosols (self-mulching grey and brown clays, and black earths) of the Lower Namoi Valley, New South Wales, Australia. Recent research however has shown that in fact deep drainage does occur. The main concern, therefore, is their movement beyond the reach of crop roots. Groundwater systems in the Lower Namoi Valley have been reported to be declining, suggesting that deep drainage is not reaching groundwater. Accumulation of salts, nutrients and

The aim of this study is to assess the biological accumulation of pesticide residues in aquatic organisms in Sai Gon - Dong Nai (SG-DN) estuary. Fish and mollusks were collected directly at the Soai Rap and Long Tau estuary of the SG-DN river system, washed and separated for taking the tissue. The organochlorine compounds from the tissue were then extracted and analyzed by gas chromatography system. The results showed that, the concentration of OCPs in Tegillarca granosa, Meretrix lyrata, Margaritifera auricularia and Bostrychus sinensis varied from 6.4 to 59.9 μg/kg, 7.2 to 322 μg/kg, 4.5 to

The level of contamination by organic pollutants were detected in 20 samples, 9 samples were sediments from the river Jevišovka, which is located in the South Moravia and 11 samples represented arable soil samples and were collected in the vicinity of this river. In the theoretical part are characterized both groups of s

Abstract:

Byla provedena studie bioakumulace POP v potravním řetězci a historických trendů hladin POP v sedimentech Brněnské přehrady. Současné úrovně kontaminantů byly stanoveny v jelci tloušti z řeky Svratky a rovněž byla posouzena hygienická kvalita ryb z rekreačního rybolovu. Současné úrovně POP v terestrickém ekosystému byly posouzeny pomocí analýz jehličí jako přirozeného indikátoru znečištění. Studium jedinců tří druhů dravých ptáků z ČR bylo zaměřeno na zhodnocení kontaminace těchto vrcholných predátorů POP. S pomocí analýz vybraných druhů ryb ze Záhlinických rybníků byl rovněž studován proces b

Abstract:

In this study, the Persistent Organic Pollutants (POPs) specifically<br>17 Organochlorine Pesticides (OCPs) and 19 Polycyclic Aromatic Hydrocarbons (PAHs) were evaluated in the sediment samples of Balikesir (Ikizcetepeler) Dam Lake. Sixteen sampling points were chosen for determination of concentrations of OCPs and PAHs After ultrasonic bath extraction of the sediment samples GC-MS was used as analytical tool. Extraction efficiencies changes from 63.8 to 87.4% depending on the type of the POPs. Average OCP concentration was found in the range of 3.33-379 &micro<br>g/kg a, average PAH

In the present work, POPs were determined in honey samples from different geographic regions, evaluating both the quality and safety of honey as food, and the environmental contamination of the studied regions. Organochlorine pesticides were analysed in 186 samples from t

O objetivo deste trabalho foi a seleção de bactérias capazes de biodegradar os pesticidas organoclorados dieldrin, DDD e PCP. Inicialmente, foram realizados os ensaios de tolerância visando à seleção das bactérias degradadoras; posteriormente foram realizados os ensaios de biodegradação em meio liquido utilizando a bactéria selecionada. Dentre as 14 linhagens bacterianas isoladas testadas, selecionou-se a linhagem Pseudomonas aeruginosa L2-1 por apresentar maior tolerância a todos os pesticidas. Os ensaios de biodegradação foram realizados em diferentes meios de cultura, variando-se a concentr

Abstract:

Os compostos organoclorados causam grande impacto na natureza devido a três características básicas: persistência ambiental, bioacumulação e alta toxicidade. Os mamíferos marinhos estão entre os organismos mais vulneráveis à toxicidade crônica desses contaminantes porque, além de concentrá-los em grande quantidade, a fêmea transfere parte de sua carga ao filhote durante a gestação e a lactação. Assim, o presente trabalho teve como objetivos otimizar uma metodologia para determinação de organoclorados (pesticidas e PCBs) em matrizes gordurosas e verificar a ocorrência dos mesmos na gordura subc

Abstract:

The impact of multiple anthropogenic stressors on the marine environment has increased to large extents within the past few decades. Piscivorous fish can bioaccumulate pollutans to significantly higher concentrations than those found in the water or sediments, due to the lipid solubility and resistance of these compounds to numerous degenerative processes. The use of fish from different hydrological settings as bio-indicators represents a useful complementary choice to evaluate the levels and responses of marine organisms to pollutans, and to assess the global marine status.

Para além do contacto direto com produtos onde estes contaminantes são aplicados, a exposição ocorre principalmente porque estes químicos se libertam destes materiais e acumulam-se no ambiente, tornando-se desta forma disponíveis para serem consumidos involuntariamente pelos humanos. Durante muito tempo a alimentação foi considerada como a principal via da exposição dos humanos a diversas classes de contaminantes, i
