“…Although the use of OC pesticides is restricted to a few activities by the Ordinance No. 329 dated 9/2/1985 (ANVISA, 1985) due to their persistence, metabolites can be found mainly in the soil, sediments, and water (Tian et al, 2015;Garrison et al, 2014).…”

ABSTRACT:The knowledge of pesticide residual concentrations in the environment is important to understand the threats to the environment and human health, especially when natural resources are used for human consumption. In this context, this study aimed to assess the potential ecological risk and respective sources of sediment contamination by organochlorine and organophosphorus pesticides. The study site was an urban lake located in Cascavel city, western Paraná state, Brazil, where the history of land use and occupation in the urban environment is typically agricultural. Surface sediment samples were collected every three months from April 2010 to June 2013 at five different collection points, totaling 65 samples. Analyses showed that contamination by organochlorine pesticides is related to agricultural activities in the past, with a low ecological risk to benthic organisms. Conversely, organophosphorus pesticides presented a recent and continuous contamination from urban activities, with a risk coefficient, especially for disulfoton, indicating a significant potential adverse effect on organisms. However, in general, the obtained results did not indicate an immediate risk to public health.

“…Important for the microbial degradation are the strength of the bonding and the degree of incorporation into the geo-polymers. Toxic effects are reduced due to limited bio-availability of bound pollutants resulting in a higher persistence and modified degradation fates relative to laboratory model systems (Garrison et al 2014). Sequential chemical treatments are applied to selectively release compounds depending on the character of incorporation (Semple et al 2003;Schwarzbauer et al 2003;Kalathoor et al 2015).…”

Sediment contamination of an urban canal—a case study approach for an integrated assessment of organic sediment contamination

Purpose The pesticide DDT and its metabolites represent a contamination risk for the aquatic environment, especially the polar metabolite DDA. The study provides a quantitative assessment of long-term pollution risks from sedimentary DDT residues with a special focus on DDA. It presents an overview of the contamination range of different DDX compounds in the sediments of a canal in Berlin (Germany), resulting from a former industrial point source that has implications for drinking water resources in the nearby area. The comprehensive analysis scheme provides information on free accessible and potentially metabolized precursors also in the non-extractable residues. This allows a quantitative assessment of the DDA pollution potential derived from the sedimentary DDT residues. Materials and methods The area was investigated for fine-grained sediment by means of a geo-electric mapping. Twelve sediment cores were taken in four areas (three in each section). A wider range of precursor metabolites has been included due to their transformation potential to the polar metabolite DDA. The sediments were analysed quantitatively for extractable and easily releasable fractions by application of a variety of degradation techniques as well as a dispersion extraction procedure on the sediment samples. These extracts were fractionated and subsequently analysed by GC-MS. Results and discussion Concentrations were obtained for extractable and bound metabolites. Different scenarios for the calculation of the amount of contaminated sediment are displayed as a tool for contamination assessment. The formation potential of DDA as the water-soluble metabolite is presented. Several precursor metabolites, e.g. DDD and DDMS, extractable from the sediment organic matter, revealed a high potential for a long-term formation of DDA, especially in the easily releasable fraction (via hydrolysis) with a mean concentration of up to 11,000 μg g−1 dry sediment. The resulting DDA contamination potential represents a significant pollution risk for the groundwater from a downstream waterworks area and by remobilisation into the whole ecosystem and adjacent rivers. Conclusions The application of the presented methods provides a tool for a quantitative assessment of the long-term release potential of DDA under different scenarios by a comprehensive analysis of contaminated sediments (and soils). This approach can be transferred to pollutants that are also characterized by a complex metabolism accompanied by bound residue formation.

“…(Cuadro 3) representan una preocupación por ser considerados compuestos orgánicos persistentes, caracterizados por potencialidad de bioacumulación y toxicidad, además, son frecuentes en sedimentos de sistemas acuáticos en Brasil y en algunas regiones de Norteamérica (Venkatesan et al, 2010;Hunt et al, 2016). Estos compuestos son insecticidas organoclorados con potencial disrupción endocrina en humanos y altamente lipofílicos, lo que los hace bioacumulables y mediante procesos de biomagnificación son movilizados por las redes tróficas (Garrison et al, 2014). Sus residuos pueden persistir en el ambiente por periodos prolongados (7-30 años) (Yu, Tsunoda, & Tsunoda, 2011).…”

La cuenca del Lago de Tota ha sido modificada por diversas actividades humanas, como deforestación, piscicultura y el monocultivo de cebolla larga (Allium fistulosum) con un elevado uso de agroquímicos y gallinaza cruda, causando deterioro de las características ecológicas del sistema léntico de alta montaña más grande de Colombia. En este trabajo se implementaron pruebas de toxicidad para determinar posibles efectos deletéreos sobre H. attenuata y D. magna. Se aclimataron los organismos y validaron los ensayos de toxicidad en condiciones de laboratorio, posteriormente se realizó la evaluación de agua y sedimentos (elutriados) provenientes de afluentes de la cuenca del lago: Hato Laguna, El Tobal, Los Pozos y Agua Blanca, durante dos periodos hidroclimáticos contrastantes. Se evidenció una mayor sensibilidad con los ensayos en H. attenuata, ya que señalan que aguas y elutriados de Hato Laguna, El Tobal y Los Pozos generaron respuestas de subletalidad (Kruskal-Wallis; P < 0.05) y letalidad. Se registra presencia positiva de al menos cinco plaguicidas no cuantificados antes en la cuenca (clorotalonilo, aldrin, dieldrin, DDT y congéneres). Estos resultados indicarían una potencial influencia negativa de las actividades antropogénicas sobre organismos acuáticos nativos, con posibles consecuencias sobre la composición, estructura y función de las comunidades hidrobiológicas.
