“…This result might be explained by "cold condensation" theory, some semi-volatile organic compounds with high vapor pressure condense at cold latitude or altitude . The OCP concentrations in fish muscles in this study are comparable with those in fish from European high mountain lakes (Vives et al, 2004(Vives et al, , 2005). Pearson's correlation of the concentrations of ∑HCH, ∑DDT and HCB are significantly correlated with each other (HCB and ∑HCH: r = 0.901, p b 0.01; HCB and ∑DDT: r = 0.939, p b 0.01; ∑HCH and ∑DDT: r = 0.778, p b 0.05), which may suggest a similar origin.…”

Organochlorine pesticides and heavy metals were analyzed in fish from remote mountain lakes and Lhasa River in Tibetan Plateau. Concentrations of ∑HCH, ∑DDT and HCB in fish muscles were in the range of 0.13-2.6 ng/g, 0.78-23 ng/g, 0.31-3.2 ng/g based on wet weight, respectively. Heavy metals were routinely found with different levels in fish. The Cu and Zn levels were relatively high with the maximum concentrations reaching 2.0 and 6.9 μg/g, respectively. Accumulation of OCPs and heavy metals are quite different in tissues and organs. Gill seems to accumulate more OCPs due to absorption by its larger surface per tissue. Heavy metal levels were generally high in liver, eggs and gill, and low in brain and muscle. Results from this study demonstrate that the Tibetan Plateau functions as a regional contaminant convergence zone by long-range atmospheric transport and orographic cold trapping.

“…Although many of the most toxic substances introduced into the environment by human activity have been banned or restricted in use, many persist, especially in soils and sediments, and either remain in contact with food chains or can be remobilised and taken up by aquatic biota (Catalan et al, 2004;Vives et al, 2005). High levels of metals (such as mercury, Hg, and lead, Pb) and persistent organic pollutants such as polychlorinated biphenyls (PCBs) are present in the tissue of freshwater fish in arctic and alpine lakes (Grimalt et al, 2001;Vives et al, 2004a).…”

It is now accepted that some human-induced climate change is unavoidable. Potential impacts on water supply have received much attention, but relatively little is known about the concomitant changes in water quality. Projected changes in air temperature and rainfall could affect river flows and, hence, the mobility and dilution of contaminants. Increased water temperatures will affect chemical reaction kinetics and, combined with deteriorations in quality, freshwater ecological status. With increased flows there will be changes in stream power and, hence, sediment loads with the potential to alter the morphology of rivers and the transfer of sediments to lakes, thereby impacting freshwater habitats in both lake and stream systems. This paper reviews such impacts through the lens of UK surface water quality. Widely accepted climate change scenarios suggest more frequent droughts in summer, as well as flash-flooding, leading to uncontrolled discharges from urban areas to receiving water courses and estuaries. Invasion by alien species is highly likely, as is migration of species within the UK adapting to changing temperatures and flow regimes. Lower flows, reduced velocities and, hence, higher water residence times in rivers and lakes will enhance the potential for toxic algal blooms and reduce dissolved oxygen levels. Upland streams could experience increased dissolved organic carbon and colour levels, requiring action at water treatment plants to prevent toxic by-products entering public water supplies. Storms that terminate drought periods will flush nutrients from urban and rural areas or generate acid pulses in acidified upland catchments. Policy responses to climate change, such as the growth of bio-fuels or emission controls, will further impact freshwater quality.Key words climate change; water quality; rivers; catchments; lakes; estuaries; ecology; hydrochemistry Une revue des impacts potentiels du changement climatique sur la qualité des eaux de surface Résumé Il est maintenant admis qu'un certain changement climatique d'origine anthropique est inévitable. Les impacts potentiels sur l'alimentation en eau ont fait l'objet de nombreuses attentions, mais peu de connaissances sont disponibles sur les changements associés en termes de qualité de l'eau. Les changements prévus en termes de température de l'air et de précipitations pourraient affecter les écoulements des rivières et par conséquent la mobilité et la dilution des substances polluantes. Une augmentation des températures de l'eau affectera la cinétique des réactions chimiques et, par combinaison avec les dégradations de la qualité, l'état écologique des hydrosystèmes. Une augmentation des écoulements aura pour conséquences des changements dans la puissance des cours d'eau et donc aussi des charges sédimentaires qui pourront altérer la morphologie des rivières et le transfert de sédiments vers les lacs, ce qui aura des impacts sur les habitats hydrobiologiques dans les systèmes lacustres et fluviatiles.

“…Al estar debajo de la superficie, el plaguicida puede difundirse hacia la superficie o ser transportado por la humedad del suelo antes de que pueda escapar hacia la atmósfera, provocando daños ambientales a largo plazo, dentro de los cuales están la degradación de los suelos, la contaminación irreversible de los mantos freáticos, aguas continentales y costeras, la acumulación de los plaguicidas en las cadenas tróficas y el desarrollo de resistencia en los organismos como insectos, hongos o roedores (Edwards, 1976;Miglioranza et al, 1999;Dan et al, 2001;Barry y Warren 2004;Vives et al, 2005;Albert et al, 1989;Jiménez et al, 2005;Helberg et al, 2005;Ólafsdóttir et al, 2005;Thomas et al, 2012;Morales et al, 2017;Varol et al, 2017).…”

ResumenRecientemente se han reportado residuos de plaguicidas en el ambiente como resultado de las aplicaciones de estos productos durante varias décadas. A nivel mundial se presentan problemas atribuidos a los efectos de la contaminación por plaguicidas sobre los recursos naturales; sin embargo, en México, no existen suficientes estudios de contaminación por plaguicidas. El objetivo fue evaluar la presencia de plaguicidas en suelos de siete localidades de cinco municipios de la Comarca Lagunera en el estado de Coahuila, se realizó un muestreo de suelos a cinco profundidades (0-8, 8-23, 23-38, 38-53 y 53-68 cm) a razón de una muestra compuesta por hectárea para determinar el grado de contaminación del suelo por plaguicidas. Se utilizó el método soxhlet para la extracción de plaguicidas en la muestra y un Kuderna Danish, para la concentración. Se utilizó un cromatografó de gases. Se encontró que el díeldrin fue el único plaguicida organoclorado presente en los suelos estudiados; las capas superficiales del suelo (0-8 y 8-23 cm) mostraron las mayores concentraciones de díeldrin. El AbstractPesticide residues have recently been reported in the environment as a result of applications of these products for several decades. Globally, there are problems attributed to the effects of pesticide contamination on natural resources; however, in Mexico, there are not enough studies of pesticide contamination. The objective was to evaluate the presence of pesticides in soils of seven localities of five municipalities of the Comarca Lagunera in the state of Coahuila, a soil sampling at five depths (0-8, 8-23, 23-38, 38-53 and 53-68 cm) at the rate of a composite sample per hectare to determine the degree of soil contamination by pesticides. The soxhlet method was used for the extraction of pesticides in the sample and a Danish Kuderna for the concentration. Gas chromatography was used. It was found that dieldrin was the only organochlorine pesticide present in soils studied; the superficial layers of the soil (0-8 and 8-23 cm) showed the highest concentrations of dieldrin.
